I think I set it up right ?

main olive Sep 13, 2019, 6:02 AM

#

missing spaces

#

line 10, should be if [[ "${UID}" -ne 0 ]]

#

[[ is actually a separate shell token, which behaves just like a command (so it needs to be separated with spaces)

#

in fact, the regular [ is a separate binary

I recommend this site to lint your shell scripts https://www.shellcheck.net/

ShellCheck finds bugs in your shell scripts

green sigil Sep 13, 2019, 6:07 AM

#

oh ok thank you @main olive

#

thank you @warped nimbus

#

I'm using atom to write them

green sigil Sep 13, 2019, 6:38 AM

#

ok hmm

#

I changed the spacing, and script seems to be running slow

main olive Sep 13, 2019, 6:40 AM

#

slow?

#

if you add set -x to the top of the script, it will show you exactly what commands are being executed (and what are slowing it down)

green sigil Sep 13, 2019, 6:41 AM

#

okay I'll try

#

set -x

#This script creats a new  user on the local system.

# You will be prompted to enter the username (login), the person name, and a password.

# The username, password, and host for the account will be displayed

#Make sure the script is being executed with super user privileges.
if [[ "${UID}" -ne 0 ]]
then
  echo 'Please run with sudo or as root'
  exit 1
fi

#Get the username(login).
read - p 'Enter the username to create: ' USER_NAME

# Get the real name (contents for the description field).
read -p 'Enter the name of the prson or application that will be using this account: ' COMMENT

#Get the password.
read -p 'Enter the password to use for the account: ' PASSWORD

#Create the account.
useradd -c "${COMMENT}" -m ${USER_NAME}

# Check to see if the useradd command succeeded.

# WE don't want to tell the user that an account was cretaed when it hasn't been.
if [[ "${UID}" -ne 0 ]]
then
  echo 'The account could not be created.'
  exit 1
fi

# set the password
echo ${PASSWORD} | passwd --stdin ${USER_NAME}

if [[ "${?}" -ne 0 ]]
then
  echo 'The password for the account could not be set.'
  exit 1
fi

#Force password change on first login
passwd -e ${USER_NAME}

#Display the username, password, and the host where the user was created.
echo
echo 'username:'
echo "${USER_NAME}"
echo
echo 'password:'
echo "${PASSWORD}"
echo
echo 'host:'
echo "${HOSTNAME}"
exit 0

#

like that ?

#

this is what I'm getting now ```+ [[ 1000 -ne 0 ]]

echo 'Please run with sudo or as root'
Please run with sudo or as root
exit 1```

#

what does set -x do ?

main olive Sep 13, 2019, 6:48 AM

#

it prints out every line of the script that's being executed

#

also, it's checking if your uid is 0 (which it isn't - it's 1000)

#

so you need to run the script as root

#

ie using sudo

green sigil Sep 13, 2019, 6:49 AM

#

i'm running it like this sudo ./add_local_user.sh

#

that should work right or should I sudo su ?

main olive Sep 13, 2019, 6:50 AM

#

that should indeed work

#

hol up

#

what

#

i'm not sure what's going on here

#

oh, of course

#

sudo leaves $UID to the original executing user

#

you need to change that to $EUID instead (effective uid)

green sigil Sep 13, 2019, 6:51 AM

#

oh my my spacing and everything is bad

main olive Sep 13, 2019, 6:51 AM

#

if [[ "${EUID}" -ne 0 ]]

green sigil Sep 13, 2019, 6:52 AM

#

yeah I'm using the site that mark suggested. I started to write the script in VIM

#

and then I was like this causing mistakes and switch to Visual Studio Code

#

read -p 'Enter the username to create: ' USER_NAME
^-- SC2162: read without -r will mangle backslashes.```  I don't understand this error from the site  that Mark provided

#

why do I have to use -r ?

main olive Sep 13, 2019, 6:54 AM

#

you probably don't need to worry about that

green sigil Sep 13, 2019, 6:54 AM

#

When I'm putting it in the script on shellcheck it's making the errors go away

main olive Sep 13, 2019, 6:54 AM

#

if you don't use -r, backslashes (\) will be interpreted instead of being read raw

green sigil Sep 13, 2019, 6:55 AM

#

so always use -r for read ?

main olive Sep 13, 2019, 6:55 AM

#

actually, scratch that

#

backslashes will be stripped entirely

#

which is actually exactly what you want when adding passwords, you don't want anyone entering newlines as their password

linter warnings can generally be considered a suggestion instead of a rule and you should choose to follow the suggestion only depending on your use case

in this case, the linter is wrong

green sigil Sep 13, 2019, 6:58 AM

i'd personally not, no

green sigil Sep 13, 2019, 6:58 AM

thank you for helping @main olive

np dude

green sigil Sep 13, 2019, 6:59 AM

#

@main olive how long did the script take you to run ?

#

It's not outputting anything to me

main olive Sep 13, 2019, 7:01 AM

#

you have an error

#

read - p 'Enter the username to create: ' USER_NAME

#

there's an extra space, needs to be -p

green sigil Sep 13, 2019, 7:01 AM

#

oh ok thank you

main olive Sep 13, 2019, 7:02 AM

#

also, my passwd does not have an --stdin flag

#

might be different for you, but that line doesn't work for me

green sigil Sep 13, 2019, 7:02 AM

#

like this one ? # set the password echo ${PASSWORD} | passwd --stdin ${USER_NAME} ?

main olive Sep 13, 2019, 7:02 AM

#

yeah

green sigil Sep 13, 2019, 7:03 AM

#

#Force password change on first login
passwd -e ${USER_NAME}``` this one should have the  ```--stdin``` ?

main olive Sep 13, 2019, 7:03 AM

#

no, what I'm saying is that my passwd binary doesn't understand --stdin at all, and throws an error

green sigil Sep 13, 2019, 7:04 AM

#

ah ok but I fixed the spacing and stuff it's working now

#

and asking for user name input

#

learned a lot

main olive Sep 13, 2019, 7:04 AM

How to Force User to Change Password at Next Login in Linux

In this article, we will explain two different ways to force a user to change his/her password at the next login in Linux using passwd and chage commands.

#

also, you could just run the passwd command interactively after useradd instead of using read

#

since the user running the scirpt will be typing the password anyway

I'm a networking noob. Is there a way of having floating IPs inside of VPNs without a dedicated router? I define the routes manually (in WireGuard, via AllowedIPs) and while they're usually exact.ip/32, from my understanding I would need /24 on all servers here, which doesn't quite work..

loud wave Sep 17, 2019, 1:00 AM

#

@silver gate Hey, saw you left TPH, but wanted to give you a solution anyways...simplest thing is to use cut:

#!/usr/bin/env bash

IFS=$'\n'
file_array=($(ls -lS "$PWD" | grep -v "^d" | awk '{ print $9, $5 }'))
nb_array="${#file_array[@]}"
printf "%-30s %-20s\n" "File name" "File size"
for (( i=0; i < "$nb_array"; i++ )); do
    name=$(echo "${file_array[i]}" | cut -d ' ' -f 1)
    size=$(echo "${file_array[i]}" | cut -d ' ' -f 2)
    printf "%-30s %-20d\n" "$name" "$size"
done
unset IFS

robust cave Sep 17, 2019, 2:47 AM

#

@loud wave I don't know much bash, so I'm primarily just curious, but is your above code not equivalent to something like this?

printf "%-30s %-20s\n" "File name" "File size"
ls -lS "$PWD" | awk '!/^d/ { printf "%-30s %-20d\n", $9, $5 }'

just wondering if your code takes care of some edge case I've forgotten about

loud wave Sep 17, 2019, 3:21 AM

#

nope, that'll do it

#

not as experienced with awk though so I don't remember simple things sweating

warped nimbus Sep 17, 2019, 5:34 AM

#

awk is crazy

#

it's a turing complete language

robust cave Sep 17, 2019, 5:38 AM

#

it's awksome

silver gate Sep 17, 2019, 6:12 AM

#

@loud wave Holy cow, I like your determination, thanks a lot

warped nimbus Sep 17, 2019, 6:47 AM

#

Horrifically awesome maybe BlobSweatAnimated

boreal kestrel Sep 17, 2019, 3:14 PM

#

That script won't handle file names with spaces well. It will print only the prefix of the first space. So for example if you have two files named "I am a file" and "I am another file", then you will get two rows named "I"

#

@loud wave

#

Although I don't see the conversation context for requirements so maybe that's not a big deal? @silver gate

#

#!/usr/bin/env bash

IFS=$'\n'
for file in $(find ./ -maxdepth 1 -type f -printf '%f\n')
do
        printf '%s\t%s\n' "$(stat -c%s "${file}")" "${file}"
done

Output uses tabs instead of spaces, but it will play a lot nicer with other GNU coreutils because of it. Importantly, using find instead of ls to get the filenames

tall coyote Sep 17, 2019, 5:05 PM

#

there are times when I pipe stuff like ss -tp | less and the format gets screwed up

#

is there any argument to make it work and fill the width of my terminal properly? I know ANSI colors can work with an argument after all

boreal kestrel Sep 17, 2019, 7:15 PM

#

Programs like ss are the exact opposite of GNU coreutils. Instead of using the standard \t to separate columns, ss decides to columnate stuff itself. So who knows exactly how wide each column should be and you can't just pass it through cut.

At least it's not as bad as apt or nmcli which completely changes output if it's being piped somewhere (!@#$ that). So at least you can fix ss output by changing spaces to tabs:
ss -tp | tr -s ' ' '\t'. If you're only interested in specific columns, you can then pipe it through cut:
ss -tp | tr -s ' ' '\t' | cut -f 5,6 would give you remote peers and the local process info using it

#

That of course could break if any of the columns includes a space in the data for the column (for example, if the process name has a space...)

So I got a 2nd SSD, so I can put Ubuntu on there and dual boot Windows 10. Now, I have 480GB of free space. All of it is for Ubuntu, so how much should I allocate to root, home, and swap?

main olive Sep 18, 2019, 5:57 AM

#

I usually have 1.5x of my memory as the swap size

#

as for root/home, depends on how much stuff you're going to be installing

#

I'd personally go 100G for root (just to be safe), rest for /home

warped nimbus Sep 18, 2019, 5:10 PM

#

I want to use a pihole as my DHCP server. However, when the pihole's old lease from my router runs out, the pihole basically drops off the network and now my entire network has no DHCP.

#

The rpi disappears from the connected devices on my router and I'm unable to access the pihole admin panel or ssh into the rpi

#

I have to enable DHCP on my router to be able to do that

#

I don't know why this happens. I configured my rpi to use a static IP: ```
source-directory /etc/network/interfaces.d

auto lo
iface lo inet loopback

auto eth0
allow-hotplug eth0
iface eth0 inet static
address 192.168.0.12
netmask 255.255.255.0
gateway 192.168.0.1

#

Is there anything else I have to do (maybe in my router?)

uneven silo Sep 18, 2019, 5:48 PM

#

maybe tell your router to assign the pi a static ip

warped nimbus Sep 18, 2019, 5:52 PM

#

Yeah I've already done that though I don't think it even matters. My router is not a DHCP server and the pi is not configured to use DHCP. I think that static IP setting is only in effect when DHCP is being used

main olive Sep 18, 2019, 6:37 PM

#

hmmm

#

if you try manually renewing the lease from the pi after it's timed out, what happens? (not sure how you'll accomplish this, maybe a timed script or use serial access)

#

ie by reupping the network interface or something

warped nimbus Sep 18, 2019, 6:39 PM

#

I don't have a way to do that. If the pi is off the network I have no way to communicate with it

#

I don't have the cable to hook up my monitor to it

#

I rely on ssh working

#

I have tried restarting the pi and replugging the ethernet cable but that does nothing

#

I'm not understanding why the pi is reliant on DHCP. I thought if I set a static IP then DHCP wouldn't matter. Why does the DHCP lease expiring have an effect on it

#

Oh you know what I just remembered reading I should disable the dhcp services but never did that

boreal kestrel Sep 18, 2019, 6:53 PM

#

@warped nimbus did you get it figured out? the tl;dr is you should only have one dhcp server for a given network segment. If you have a router and a pihole both responding to dhcp requests, you're going to have a bad time

warped nimbus Sep 18, 2019, 6:54 PM

#

Not yet. I know that I should only have one DHCP server and that is how I had it set it. Disabled the router's and enabled the pihole's

#

It's just that the pi was still relying on the router's old dhcp lease

#

I think I disabled dhcp now on the pi though. dhcpd service not running

#

no dhclient process

#

now I wait a day and see if it still works

boreal kestrel Sep 18, 2019, 7:40 PM

#

Why wait a day?

warped nimbus Sep 18, 2019, 8:03 PM

#

That's when it would stop working

#

I am pretty certain it's not using DHCP anymore anyway though

boreal kestrel Sep 19, 2019, 1:12 AM

#

I would have simply forced a dhcp lease reset then reboot the pihole

warped nimbus Sep 19, 2019, 1:23 AM

#

How could a lease reset even be forced when DHCP is disabled?

#

And yes I did reboot

boreal kestrel Sep 19, 2019, 1:32 AM

#

Ahh indeed. I keep my pihole on dhcp, and just statically assign an address to the MAC, and other hosts' dhcp responses include the pihole as their first and only DNS server.

warped nimbus Sep 19, 2019, 1:33 AM

#

Then you are not using pihole as the DHCP server?

#

Cause that's what I'm doing

boreal kestrel Sep 19, 2019, 1:35 AM

#

Nope. I run pihole in a Docker container on the same host as the services it's protecting. Then I can see per-host or per-network pihole stats too.

main olive Sep 19, 2019, 3:45 AM

#

@warped nimbus have you configured your DHCP server on the pihole so that the pi itself is unmanaged and has a static IP?

warped nimbus Sep 19, 2019, 3:46 AM

#

Well yeah, that's what the network config I showed does, right?

main olive Sep 19, 2019, 3:47 AM

#

that's just suggesting the DHCP server that you don't want to be assigned a dynamic IP - it's up to the server itself to implement that. Some servers ignore that and assign you an IP anyways

#

for example, I actually have to add rules in my router for static routes, just modifying the network interface settings on the client device itself doesn't work

warped nimbus Sep 19, 2019, 3:49 AM

#

I see. I've not done that, no. I didn't think the pi would try to use itself as a DHCP server after I've disabled dhcpd

main olive Sep 19, 2019, 3:50 AM

#

You might be surprised. IIRC last time I used pihole, there was a "static DHCP leases" section

#

have a look at that

warped nimbus Sep 19, 2019, 3:50 AM

#

Yeah, I've configured that for other devices but not the pi itself

#

I guess adding it wouldn't hurt

main olive Sep 19, 2019, 3:51 AM

#

another one of my routers very aggressively hands out dynamic IPs even if the device has any sort of DHCP requests disabled

#

just, like, in response to a new mac appearing on the network

warped nimbus Sep 19, 2019, 3:52 AM

#

So it's completely up to the router whether it wants to respect the clients' wishes to not be assigned an IP dynamically?

main olive Sep 19, 2019, 3:52 AM

#

Yep

#

implementation wise, it'd not be very sane not to respect those wishes, but... god damn have I seen some dumb shit over the years

warped nimbus Sep 19, 2019, 3:54 AM

#

Well if anything pihole will likely be more sane than than my old cheap router's dhcp server

main olive Sep 19, 2019, 4:09 AM

#

@warped nimbus I think it was mikrotik who actively didn't add static IPs to the routing table unless explicitly set in the DHCP rule list, as to "reserve" the IP and guarantee that the DHCP server doesn't assign it to someone else, possibly causing problems

timid mist Sep 19, 2019, 4:13 AM

#

@warped nimbus What you said earlier is confusing to me, “_ I want to use a pihole as my DHCP server. However, when the pihole's old lease from my router runs out, the pihole basically drops off the network and now my entire network has no DHCP._” So, you are using dhcpd on the pihole to serve addresses to your network, but the pihole is receiving an address from your router’s dhcpd. If you then set a static IP address on the pihole, it probably won’t match the address the router assigned ==> no connectivity. Am I understanding your setup correctly?

main olive Sep 19, 2019, 4:14 AM

#

did I not read that he disabled DHCP on his router?

#

I'm assuming his router has assigned the pihole the static ip

#

as long as the gateway is not acting as the dhcp server it should be fine

#

man FUCK networking

timid mist Sep 19, 2019, 4:15 AM

#

So long as the address assigned in the router matches the one in the pihole, of course

#

dhcp in both is fine as long as they are assigning different ranges of addresses.

main olive Sep 19, 2019, 4:17 AM

#

as long as the subnets don't collide yeah

warped nimbus Sep 19, 2019, 4:17 AM

#

I started off with my router being the DHCP server. Therefore the pi had an active lease when I connected to it to go and switch the pi to being the sole DHCP server. So even with DHCP enabled on the pi and disabled on the router, the pi still had an active lease from the router.

#

And it worked until the lease ran out

#

At least that's what I think was going on

#

My pi was still relying on DHCP for some reason and the solution was to disable the dhcpd service

#

when I did that it seems to truly be using a static IP now

#

And the problem wasn't that it had a different address. It had no address. I couldn't see it on the network at all lol

timid mist Sep 19, 2019, 4:22 AM

#

It’s OK to rely on a chain of dhcp servers. Consider a home cable modem typically gets its IP from the network dhcp server, but the same cable modem (router) serves up IP addresses to all the devices in your house. As xx said above, must be different subnets.
What IP’s are you using?

warped nimbus Sep 19, 2019, 4:25 AM

#

I'm not relying on a chain of DHCP servers. I'm trying to replace one DHCP server (my router) with another (my pi)

timid mist Sep 19, 2019, 4:26 AM

#

Where was the router getting its IP from?

warped nimbus Sep 19, 2019, 4:26 AM

#

Itself?

timid mist Sep 19, 2019, 4:26 AM

#

No

worn apex Sep 19, 2019, 4:26 AM

#

er

#

the router generally has different addresses on both subnets

#

its own IP is typically static e.g. 10.0.0.1 or 192.168.0.1

timid mist Sep 19, 2019, 4:27 AM

#

What was the IP of the router’s gateway?

warped nimbus Sep 19, 2019, 4:27 AM

#

192.168.0.1

timid mist Sep 19, 2019, 4:27 AM

#

That’s its local IP

warped nimbus Sep 19, 2019, 4:27 AM

#

It's also the gateway is it not

worn apex Sep 19, 2019, 4:27 AM

#

you should configure the pi with a static ip address too

timid mist Sep 19, 2019, 4:28 AM

#

There is a different IP towards the Internet

worn apex Sep 19, 2019, 4:28 AM

#

@timid mist i'm not sure why you think the public IP matters

warped nimbus Sep 19, 2019, 4:29 AM

#

Oh I thought you were speaking locally

worn apex Sep 19, 2019, 4:29 AM

#

anyway, you should configure the pi with a static ip address. a real static ip address, not a fixed dhcp assignment

warped nimbus Sep 19, 2019, 4:29 AM

#

@worn apex Yeah, I thought I did. Does this look good to you? https://discordapp.com/channels/267624335836053506/491523972836360192/623929355038359552

hmm

timid mist Sep 19, 2019, 4:30 AM

#

See where I’m going @worn apex ?

worn apex Sep 19, 2019, 4:30 AM

#

can you run arp -a on one of the other client machines

#

do you know the MAC address of the pi?

warped nimbus Sep 19, 2019, 4:31 AM

#

Yeah

worn apex Sep 19, 2019, 4:31 AM

#

I really don't see where you're going, @timid mist , the problem seems confined to the local network segment (though obviously the router will still need to be used as a gateway)

warped nimbus Sep 19, 2019, 4:32 AM

#

Just to be clear I think I solved the problem

#

But I am not really sure

#

I just assumed dhcp was the issue here

#

Cause everything seemed to point to it being the issue

timid mist Sep 19, 2019, 4:33 AM

#

@warped nimbus your old router has one IP address towards the Internet and a different IP address for your local network. Your rpi needs to have a similar configuration. The IP config you posted makes it look like you put 192.168.0.12 IP address towards the Internet and it should be towards your local network.

worn apex Sep 19, 2019, 4:34 AM

#

he's not replacing the router, only the DHCP server

#

the router will still act as switch and gateway

warped nimbus Sep 19, 2019, 4:34 AM

#

Yes, that's correct

Just DHCP

timid mist Sep 19, 2019, 4:34 AM

#

Ah, didn’t catch that part!

worn apex Sep 19, 2019, 4:34 AM

#

"routers" these days are kind of all-in-one boxes so it's confusing to talk about

warped nimbus Sep 19, 2019, 4:36 AM

#

Oh and here's that arp command you asked about ```
arp -a
_gateway (192.168.0.1) at a4:2b:8c:b7:da:3a [ether] on ens33
raspberrypi (192.168.0.12) at dc:a6:32:24:eb:17 [ether] on ens33

worn apex Sep 19, 2019, 4:36 AM

#

so it can see the pi, allegedly

#

can you ping it

warped nimbus Sep 19, 2019, 4:36 AM

#

Well I can ssh into it

worn apex Sep 19, 2019, 4:36 AM

#

ok so what exactly dropped out

warped nimbus Sep 19, 2019, 4:37 AM

#

Well i think it's fine now since I disabled the dhcpd service on the pi

worn apex Sep 19, 2019, 4:37 AM

#

oh nevermind you said you fixed it by disabling dhcpd

warped nimbus Sep 19, 2019, 4:37 AM

#

yes

worn apex Sep 19, 2019, 4:37 AM

#

wait, dhcpd?

#

do you mean dhcpcd?

warped nimbus Sep 19, 2019, 4:37 AM

#

maybe

#

yeah, oops

worn apex Sep 19, 2019, 4:38 AM

#

dhcpd is the server itself, dhcpcd is the client

warped nimbus Sep 19, 2019, 4:38 AM

#

not enough vowels in these acronyms lol

worn apex Sep 19, 2019, 4:40 AM

#

i'm used to desktop machines with network manager

#

where you can't have something accidentally configured as both static and dynamic at the same time

#

it is a royal pain to configure without a gui though

warped nimbus Sep 19, 2019, 4:41 AM

#

I think I could have disabled dhcp by changing the config file for the interface instead of disabling the service

timid mist Sep 19, 2019, 4:41 AM

#

If you have turned off the dhcp server in the router, and you turned off dhcpd in the pi, then no one is getting IP addresses automatically assigned.

warped nimbus Sep 19, 2019, 4:41 AM

#

Yeah, I meant dhcpcd

timid mist Sep 19, 2019, 4:42 AM

#

OK

warped nimbus Sep 19, 2019, 4:42 AM

#

pihole doesn't use dhcpd for its server

#

I believe it uses dnsmasq

#

keep messing up the names...

worn apex Sep 19, 2019, 4:43 AM

#

did you restart the network/networking service after editing interfaces?

#

(what os is the pi)

timid mist Sep 19, 2019, 4:44 AM

#

So, I agree with you, turning off dhcpcd will stop interfering with your statically assigned IP

warped nimbus Sep 19, 2019, 4:44 AM

#

@worn apex Yeah I always did that but it wasn't enough. It really wanted dhcpcd off too.

worn apex Sep 19, 2019, 4:45 AM

#

weird

warped nimbus Sep 19, 2019, 4:45 AM

#

It's raspbian so basically debian

worn apex Sep 19, 2019, 4:45 AM

#

had you restarted dhcpcd? maybe dhcpcd itself still thought the interface was configured as dynamic

warped nimbus Sep 19, 2019, 4:45 AM

#

Not exactly but I restarted the pi itself multiple times

worn apex Sep 19, 2019, 4:45 AM

#

like maybe it doesn't need to be off off but it needs to know from reading interfaces that it isn't managinging the interface

#

weird

warped nimbus Sep 19, 2019, 4:45 AM

#

and it wouldn't show up as a connected device

#

There's probably some config I could have done but I don't care about dhcp on it so it's easier to just disable it

#

and if that didn't work I would have gone even further and uninstalled it

worn apex Sep 19, 2019, 4:46 AM

#

there has to be a way, and i can't think of how else it would be other than the interfaces file

warped nimbus Sep 19, 2019, 4:46 AM

#

I'm not well versed in network configs. The interface config is just what I saw mentioned

worn apex Sep 19, 2019, 4:47 AM

#

ok found it

#

https://superuser.com/questions/985082/is-there-a-way-to-disable-the-dhcp-client-in-raspbian-linux-on-a-rasperry-pi

#

apparently dhcpcd no longer uses /etc/network/interfaces for configuration and instead does its own thing

#

...this is why i like network manager, it's one program that controls everything instead of a bunch of different things that don't always talk to each other right

main olive Sep 19, 2019, 4:48 AM

#

I think the obvious solution here is to nuke dhcpcd

#

just yeet that off the pi

worn apex Sep 19, 2019, 4:49 AM

#

right

warped nimbus Sep 19, 2019, 4:49 AM

#

Disabling it seems good enough

#

Maybe if I need the disk space

worn apex Sep 19, 2019, 4:49 AM

#

you'd need a better solution if you had a more exotic scenario

#

for example, if you were building a gateway/router that needed to do DHCP over the ISP network and have a static IP on the local network, you would need a DHCP client

warped nimbus Sep 19, 2019, 4:50 AM

#

I don't know what debian uses but I found systemd-networkd to be nice on arch

#

Good enough for my basic needs anyway

worn apex Sep 19, 2019, 4:50 AM

#

yeah i keep talking about network manager but tbh it is a bit heavyweight

#

it's what all the polished gui configuration windows in the desktop environments use

#

and while it has a command line client, it's not pleasant to use that way

main olive Sep 19, 2019, 4:51 AM

#

nmtui is ok, as is nmcli once you get used to its strange opinions on command syntax

warped nimbus Sep 19, 2019, 4:51 AM

#

I prefer configs over a gui I think

#

If things aren't so fragmented

worn apex Sep 19, 2019, 4:52 AM

#

i don't think i ever heard of nmtui when this was actively a problem for me

main olive Sep 19, 2019, 12:56 PM

#

Iam getting the error "No module named 'numpy'". Wondering what the problem is, and how I can fix it. Something I need to download?

#

so you want Felonies, but not 6?

#

@main olive

#

like this?

Name: Billy Schneider

Felonies:

#

if so,

sed -E 's/(Felonies:).*/\1/' <filename>

formal schooner Sep 20, 2019, 5:14 PM

#

or do you just want the "6"?

#

use cut -d ' ' if you want to split on spaces and not tabs

I am trying to get minecraft working on linux since my windows is broke, forge universal won't load (i think its because it uses an older verison of java than what I am running) I did java -verison and got openjdk version "11.0.4". I read that forge uses java 8, wouldnt I have to use JRE instead of JDK? Since I am not developing?

#

java -version only shows the jdk

#

although it shows 8 too

#

https://gyazo.com/d76b34a20133af08431cf21c66f02875

tried running forge with java8;

#

#

same error tho;

#

no main manifest attribute, in forge-1.14.4-28.1.0-universal.jar

any ideas would be amazing

distutils.errors.DistutilsOptionError: error in setup.cfg: command 'build' has no such option 'i18n'

Anyone knows how to get rid of this error?
I get it every time I try to upgrade pip or wheel, but also when I try to run the setup.py file from the ubuntu-tweak tool (I'm on Ubuntu 18.0.4)

lucid harbor Sep 21, 2019, 10:02 AM

#

partially solved: replaced the raise ... with a pass (i.e. the function was just setting the elements of a dictionary as attributes to an object)

#

nothing broke and it works fine

#

however when you try to install ubuntu-tweak with the setup.py file it still gives the same error

#

cannot fix it because it's probably in a binary file

formal schooner Sep 21, 2019, 11:42 AM

#

@lucid harbor you probably need to install a python dep

#

Let me check what it might be called

#

Maybe https://pypi.org/project/setuptools-i18n/

PyPI

setuptools-i18n

Plugin for setuptools to build and compile i18n files

Ok... pihole issues round 2

#

This time DNS stopped working on the pihole itself

#

so it cannot resolve anything

#

etc/resolv.conf just has nameserver 127.0.0.1

#

If I understand correctly, that means pi is using itself as a DNS server

#

But that seems like a catch 22 because pihole cannot work without the pi being able to resolve things

#

Restart the pi fixed it but I don't know why this happened in the first place

#

Before rebooting, I tried specifying some nameservers in /etc/network/interfaces but had no luck. It seems I couldn't get resolvconf to update resolv.conf (it still only shows 127.0.0.1 even after rebooting)

#

I tried some of the suggestions here too https://askubuntu.com/a/225100/589656

#

I'd like to get to the bottom of this and prevent it from happening again

I think you should go back to source folder from python and install it with --with-ensurepip=install

@main olive when you run ./configure you put that flag there

main olive Sep 22, 2019, 12:12 PM

so i should reinstall python?

yea, but with the flag --with-ensurepip=install as well

ok

sudo ./configure --enable-optimizations --with-ensurepip=install

like that?

no sudo needed

to open what?

get-pip.py?

i can make the file.py into file.exe and open it into terminal with file.exe

that's not how binary works

#

wdym by make the file.py into file.exe?

main olive Sep 22, 2019, 12:54 PM

using pyinstaller

#

i can make it into .exe and run it in terminal

#

and skip the pip usage

lucid harbor Sep 22, 2019, 12:54 PM

but maybe you'll need pip later

@main olive Did you use ./configure --enable-optimizations --with-ensurepip=install last time?

#

and why doesn't it have _ctypes?

main olive Sep 22, 2019, 1:02 PM

#

yes i used that

lucid harbor Sep 22, 2019, 1:06 PM

@main olive well, I'm out of ideas. maybe you should post your problem again so if someone more experienced than me sees it, he/she can help you

@main olive is this a custom build of Python? You probably need the header files for libffi

#

that being said doing custom builds of Python is generally a terrible idea unless you really know what you're doing, you should probably use pyenv instead

@main olive that usually means compilation failed

@warped nimbus set up unbound and openresolv

#

check out https://wiki.archlinux.org/index.php/unbound

Unbound

warped nimbus Sep 23, 2019, 5:31 AM

#

Alright I will look into that

#

thanks

main olive Sep 23, 2019, 5:33 AM

#

alternatively, if you can't be fucked...

#

modify /etc/resolv.conf to point to a valid DNS server, and then chattr +i /etc/resolv.conf

main olive Sep 23, 2019, 7:19 AM

#

@warped nimbus how's it going?

warped nimbus Sep 23, 2019, 7:19 AM

Tomorrow I will let ya know

main olive Sep 23, 2019, 7:20 AM

#

fair enough :)

warped nimbus Sep 24, 2019, 12:29 AM

#

I'm using pihole so it has its own DNS server. I'm not really understanding why I would set up unbound, unless DNS resolver and DNS server are different things.

#

openresolv just seems to be an alternative to resolvconf

#

But I can try to set it up

#

If you think it'd help

grave jolt Sep 24, 2019, 1:12 AM

#

@warped nimbus its likely that your dnsmasq settings are messed up.
the local resolver will read those resolvconf settings to know who is your intended first stop for dns resolving.
the forwarder/server those settings point to then do the actual work. that forwarder/server uses different settings to know what upstream dns servers/server to query.
pi hole seems to use dnsmasq, which is a forwarder. itll forward any dns requests it doesnt understand to an upstream server that is separately configured. any domains it knows about or intentionally blocks will be handled locally

warped nimbus Sep 24, 2019, 2:17 AM

#

I knew pihole uses dnsmasq and that it forwards dns requests

#

Would pihole/dnsmasq be my local resolver then?

#

The issue here is things go wrong when pihole goes down. Was I right in saying it's likely trying to use itself to resolve?

#

I know the pi does use pihole for local requests when pihole is running

#

But what happens when pihole is off?

#

If dnsmasq is misconfigured what steps could I take to fix it? What would I be looking out for? I've only configured it via the basic settings pihole offers in the admin site

#

Like setting which dns to forward to

#

I'm not entirely sure why pihole couldn't start. I knew that the entire pi was unable to resolve anything, but why does pihole need an internet connection to start? Possibly checking for updates? I feel like if I could circumvent that and start it up, things would have probably been fixed. But still that is not an ideal situation to get myself in. I don't even know why it randomly failed in the middle of the day either.

main olive Sep 24, 2019, 6:45 AM

#

@warped nimbus "Unless DNS resolver and DNS server are different things"

#

they are

#

DNS resolver resolves using a DNS server

#

ie, a DNS resolver connects to 1.1.1.1 (a DNS server) to resolve names to IPs

grave jolt Sep 24, 2019, 6:57 AM

#

@warped nimbus what did you use as your upstream dns server? was it like cloudflare/google or did you use your router?

warped nimbus Sep 24, 2019, 4:25 PM

#

I chose google

grave jolt Sep 24, 2019, 7:16 PM

#

hm ideally dnsmasq is configured to work even if the pihole service is down but maybe not.
personally i dont use pihole, i just have my router download a dns block list from the same lists pihole uses

#

if pihole assumes an always on internet connection that could cause issues when yours goes down.
the system might be set up with pihole as a required dns step

#

@warped nimbus

warped nimbus Sep 24, 2019, 7:34 PM

#

How can I configure it to use something else with pihole is down

#

I described earlier how I tried and failed to set the nameserver with resolvconf

#

I could edit resolv.conf manually like xx suggested

#

I didn't try unbound yet because I don't fully understand how it helps

boreal kestrel Sep 24, 2019, 8:36 PM

#

just set a secondary DNS server?

grave jolt Sep 24, 2019, 8:47 PM

#

i would leave your resolve conf on localhost, since many distros run dnsmasq locally these days and it looked like the pihole setup did that too
can you share your current dnsmasq config? if its pointing to pihole locally then you could prob update it to fallback to google.

#

unfortunatly im not 100% sure how pihole's part of the software really works

#

according to https://docs.pi-hole.net/ftldns/dns-resolver/ they might actually just be running a fork of dnsmasq

warped nimbus Sep 24, 2019, 9:25 PM

#

Well here it is https://paste.pythondiscord.com/ojopohabah.py

#

/etc/dnsmasq/conf just points to /etc/dnsmasq.d/

#

which has three files

#

01-pihole.conf  02-pihole-dhcp.conf  04-pihole-static-dhcp.conf

#

I shared the first 1

#

other two do not seem relevant

grave jolt Sep 24, 2019, 9:39 PM

#

it sounds like on bootup the pihole software changes your resolveconf settings so that it points to localhost
as far as what changed it away i am not sure.
looking at this file and the pihole documentation, I think that you will always lose dns if pihole goes down because its a required step in your dns chain and pihole always resets the systems dns to point to itself unless you disable it as mentioned here https://discourse.pi-hole.net/t/how-do-i-disable-pi-hole-automatic-add-127-0-0-1-in-resolv-conf/18248/9
it also sounds like resolveconf always tries the first entry first. so in theory you could disable that autoupdate and make localhost the first dns server, then an upstream dns server the second option in case the pihole service goes down

#

however it would be better if it never went down. you could also increase the logging verbosity and check on it in case it goes down again

warped nimbus Sep 24, 2019, 9:52 PM

#

however it would be better if it never went down

Indeed. I just don't know what even happened. At the least here I was trying to make it recoverable without needing to reboot the pi.

#

It'd just be more convenient since the admin panel has a button to stop/start it.

#

But to restart pi I think my only options are to ssh or do it physically

#

However, I will look into disabling that autoupdate. My understanding is that resolvconf subscribes to certain services (e.g. dnsmasq and networking) in order to know which nameservers to set

grave jolt Sep 24, 2019, 9:56 PM

#

if they use systemd or something to start it on boot you could set the service to autorestart if it crashes

#

but i feel like something else must be going on if it does crash so maybe improve the logging settings

warped nimbus Sep 24, 2019, 9:56 PM

#

The problem with restarting pihole is that it cannot restart

#

I believe it tries to check for updates and if that fails (which would happen when DNS isn't working) it'll just completely fail to start

#

so that's why it's a catch 22

#

Maybe it's not checking for updates

#

but it does something that requires DNS to already be working

grave jolt Sep 24, 2019, 9:58 PM

#

hmmmm thats annoying

warped nimbus Sep 24, 2019, 9:59 PM

#

Regarding the logging, I tried to look but I didn't really know what I'm looking for and nothing stood out. I would love to figure out why it crashed

#

So far it has not happened again though

#

there are a lot of pihole-related logs too...

#

I'll look harder next time, if there is a next time

grave jolt Sep 24, 2019, 10:02 PM

#

looks like it does read your interfaces on startup, so if something is funky/missing there it might crash

#

eg if for some reason your network device didnt exist yet

warped nimbus Sep 24, 2019, 10:04 PM

#

Are you saying that's why it initially crashed or why I could not restart it?

#

It initially crashed when it was already running fine for many hours

grave jolt Sep 24, 2019, 10:06 PM

#

i was thinking of reasons why it might fail to restart

#

it looks like it checks a lot of stuff when the process starts, so if any of those caused it to crash it prob wouldnt be able to start back up

#

similarly if it crashed but didnt actually go away, its possible it couldnt restart because a process still had a port open

blazing wolf Sep 25, 2019, 2:53 AM

generally when i want to download something, (im on ubuntu mate) ,there is no diff section for ubuntu derivaties, so basically i download the version given for just ubuntu?

warped nimbus Sep 25, 2019, 2:54 AM

No experience with Ubuntu but presumably it would work since MATE is just a different desktop environment

blazing wolf Sep 25, 2019, 2:55 AM

ubuntu mate is debian based?

which is the best monitoring tool?

pgadmin?

cold pagoda Sep 25, 2019, 1:13 PM

something like that

green sigil Sep 26, 2019, 6:37 AM

#

oh weird

main olive Sep 26, 2019, 6:37 AM

you're not putting & anywhere are you

#

anyways, if it gives you a pid like that, you should be able to use fg to foreground it

green sigil Sep 26, 2019, 6:37 AM

#

charm. &

#

that's how you run it right ?

main olive Sep 26, 2019, 6:38 AM

#

that puts it in the background

#

remove the &

#

and the dot

green sigil Sep 26, 2019, 6:38 AM

I'm running this using wsl

#

by the way

main olive Sep 26, 2019, 6:39 AM

ok, but do what I said anyways

green sigil Sep 26, 2019, 6:39 AM

#

-bash: /mnt/c/Program: No such file or directory

#

but it's in the path I provided it

main olive Sep 26, 2019, 6:39 AM

#

escape spaces with a backslash \

#

so it's Program\ Files\ $x86$

green sigil Sep 26, 2019, 6:40 AM

#

alias charm="/mnt/c/Program Files/JetBrains/PyCharm Community Edition 2019.2.3/bin/pycharm64.exe"

#

that's what my alias looks like

main olive Sep 26, 2019, 6:40 AM

#

yes

#

like I said, escape the spaces

#

all of them

green sigil Sep 26, 2019, 6:40 AM

#

escape the spaces I understand now

#

is there a tool for something like that ?

main olive Sep 26, 2019, 6:41 AM

#

otherwise it will try executing /mnt/c/Program only and pass everything else as an argument, not a full path

#

just put \ before every space

green sigil Sep 26, 2019, 6:42 AM

#

ok

#

how do you tell a space in bash ?

sharp shell Sep 26, 2019, 6:42 AM

#

you can escape it (as xx said in his previous message with the backslash)

main olive Sep 26, 2019, 6:42 AM

#

??? what

sharp shell Sep 26, 2019, 6:42 AM

#

or you can quote the path

main olive Sep 26, 2019, 6:43 AM

#

before every space, put \. Program Files becomes Program\ Files

green sigil Sep 26, 2019, 6:43 AM

#

so would it be something like this alias charm="/mnt/c/Program Files/JetBrains/PyCharm\ Community\ Edition\ 2019.2.3/bin/pycharm64.exe"

main olive Sep 26, 2019, 6:43 AM

#

you missed the "program files"

#

but otherwise, yes

green sigil Sep 26, 2019, 6:43 AM

#

oh ok thank you

sharp shell Sep 26, 2019, 6:43 AM

#

does an alias need escaping like that when it's quoted?

main olive Sep 26, 2019, 6:44 AM

#

yep

sharp shell Sep 26, 2019, 6:44 AM

#

must be a config thing

#

weird

green sigil Sep 26, 2019, 6:44 AM

#

oh ok I'll keep that in mind I thought it didn't with quotes

main olive Sep 26, 2019, 6:44 AM

#

alias blindly replaces charm with whatever is in the quotes

#

this is by design, so you can alias arguments

green sigil Sep 26, 2019, 6:44 AM

#

oh ok @main olive

tall coyote Sep 26, 2019, 6:44 AM

you're not really escaping spaces there

@green sigil yes. You need to add the backslashes before the spaces, not replace the spaces

#

bash is better than sh

main olive Sep 26, 2019, 6:50 AM

@sharp shell zsh gang

green sigil Sep 26, 2019, 6:51 AM

oh so add two back slashes ? @main olive ?

sharp shell Sep 26, 2019, 6:51 AM

#

haha

#

so add a \ in front of a space, yeah

#

\ is an escape

#

meaning it assumes it's part of the arg still

not that the space means another arg is starting

which is the default

when i was on winblows though i used 4 spaces in place of tabs

at least i could highlight and distinguish when they're used that way

you can put it in bashrc

vim is one choice which is fine

it's a personal choice

is there a good app for path swaping ?

or dealing with this ?

tall coyote Sep 26, 2019, 7:16 AM

#

what do you mean?

green sigil Sep 26, 2019, 7:16 AM

#

like taking a windows path and converting

#

to a unix path

#

or dealing with spaces

tall coyote Sep 26, 2019, 7:19 AM

#

for spaces you can use quotes instead

#

my\ path is the same as "my path"... actually, what you're doing is telling what's part of a single argument

#

a program would take "my" and "path" as different arguments, if you want an explanation

green sigil Sep 26, 2019, 7:21 AM

#

oh ok

#

so there would be no way to automate this ?

tall coyote Sep 26, 2019, 7:24 AM

#

about the spaces, I don't know really, I'm not that savy on bash

green sigil Sep 26, 2019, 7:25 AM

hey all quick question yesterday I got really good help here. I was able to make a lot of progress. for fun I'm setting up a wsl environment

#

I'm running into a weird issue Cannot find file '\\wsl$\Ubuntu\home\

#

I'm not sure where to actually go about fixing this

#

I'm looking up stuff on google not sure how the fixes apply to me

#

I basically made aliases

#

I'm trying to make a file with my alias that launches pycharm charm app.py

#

I'm wondering if it's actually trying to find file instead of creating it

#

I can create files like vim app.py

uneven silo Sep 26, 2019, 10:42 PM

looks like pycharm is freaking out trying to resolve the wsl links

#

any ideas ?

warped nimbus Sep 27, 2019, 4:10 AM

#

You may need to install tkinter as a separate package

#

It doesn't always come with python I believe

#

https://packages.ubuntu.com/search?keywords=tkinter&searchon=all&suite=bionic&section=all

#

Probably what you want is python3-tk

green sigil Sep 27, 2019, 4:16 AM

oh ok I'll try that Mark

#

thank you

@warped nimbus Can do you that sudo apt-get install python3-tk ?

Which Python version does Ubuntu 18.04 come with by default?

green sigil Sep 27, 2019, 4:18 AM

#

I think it's 2.7

warped nimbus Sep 27, 2019, 4:18 AM

#

I don't think it's Python 3.7, is it?

green sigil Sep 27, 2019, 4:18 AM

#

It' s not 3.7

warped nimbus Sep 27, 2019, 4:18 AM

#

Yeah it has 2.7 and also some version of 3

#

Rightttttt

#

So

#

How did you get Python 3.7?

#

Did you build from source?

green sigil Sep 27, 2019, 4:18 AM

#

I think so

#

don't remember the command for that one

#

here's I made 3.7.4 default by aliasing python

#

I'm actually not sure how to get tkinter on 3.7

green sigil Sep 27, 2019, 4:19 AM

#

to python 3

warped nimbus Sep 27, 2019, 4:19 AM

#

I dunno if it's like just an extra build option when building Python, to also build tkinter

#

or if it's separate

green sigil Sep 27, 2019, 4:20 AM

#

oh ok

#

so how should I approach ?

warped nimbus Sep 27, 2019, 4:21 AM

#

Do some research online about how to install it if you've build Python from source

green sigil Sep 27, 2019, 4:21 AM

#

I've been reading this https://stackoverflow.com/questions/5459444/tkinter-python-may-not-be-configured-for-tk

warped nimbus Sep 27, 2019, 4:21 AM

#

Or you could be less specific and just search for how to get it with 3.7 on Ubuntu

green sigil Sep 27, 2019, 4:21 AM

#

I'm not sure how do a TCL/ Tk like they suggested

#

even this Mark https://stackoverflow.com/questions/6084416/tkinter-module-not-found-on-ubuntu

warped nimbus Sep 27, 2019, 4:23 AM

#

That first link mentions installing tk-dev then building Python from source (and yes in your case that means re-installing Python I believe)

#

That sounds like a good lead

green sigil Sep 27, 2019, 4:24 AM

#

I'll look up how to re install python on linux ?

#

I'm removing both 3 and 2.7

#

to have a fresh start

warped nimbus Sep 27, 2019, 4:32 AM

#

You should not do that

green sigil Sep 27, 2019, 4:32 AM

#

ok

warped nimbus Sep 27, 2019, 4:33 AM

#

I don't know the specifics of Ubuntu but typically the Python versions that a distro comes with are actually needed by the distro itself

#

or some tools that you use

#

You can uninstall and re-install 3.7 safely since that did not come with the distro

green sigil Sep 27, 2019, 4:34 AM

#

ok thanks for the tip

yep cleaning up things now

green sigil Sep 27, 2019, 5:09 AM

I thought Linux wasn’t Unix?

linux is the name of the kernel & most/all unix os's run on it

main olive Sep 28, 2019, 1:31 PM

#

@edgy minnow no

#

@ionic swift correct. Linux is Unix-like, as in it behaves mostly like a Unix system

#

IIRC BSD is more closely related to Unix as it's based off actual Unix code, and not just its design principles

#

although I get your point... why is the channel named "Unix" if we ever only talk about Linux - not even other Unix-like systems such as BSD or MacOS

? linux is the kernel. even if its become common to say linux to mean both kernel and os/gnu

sage solar Sep 28, 2019, 1:45 PM

#

but you also said that most unix like operating systems use linux

#

and thats just wrong

#

there are all the BSD ones, there is max os which runs upon darwin, there is solaris, there is the Hurd kernel by GNU

#

linux is just one out of many

#

@edgy minnow

#

@main olive and about your question, considering im bascially working with openBSD day in day out now, maybe thats gonna change ^^

main olive Sep 28, 2019, 1:49 PM

@edgy minnow yeah, I'm not saying it isn't. I'm commenting about "all Unix OSs run Linux", which is just... wrong in so many ways

main olive Sep 28, 2019, 1:52 PM

#

Unix is a real operating system, first made in 1970. Many operating systems derived from Unix (ie the actual code). Linux isn't even one of them. Furthermore, all "Unix OSs" don't run Linux. MacOS is more Unix than Linux and it runs the Darwin kernel

#

ye

uneven silo Sep 28, 2019, 1:52 PM

#

mac is mach + unix iirc

sage solar Sep 28, 2019, 1:52 PM

#

mac is a darwin kernel + apple userland

formal schooner Sep 28, 2019, 1:53 PM

#

"XNU" which i guess is ~~based on darwin~~ the kernel in Darwin

#

fun fact, XNU is open source although it's not very useful as just a kernel https://opensource.apple.com/source/xnu/

sage solar Sep 28, 2019, 1:53 PM

#

but even though all of them are unix theyre still so different on very basic things

#

for example partitioning on BSD systems is such a weird thing to do

formal schooner Sep 28, 2019, 1:54 PM

#

so Darwin + some kind of miniml userspace = XNU, and XNU + all the fancy proprietary Apple stuff = macOS

#

isnt unix basically a syscall convention at this point

sage solar Sep 28, 2019, 1:54 PM

#

in linux you have like

/dev/sda sdb sdc for your device

on bsd its

/dev/sd1 2 ....

and then those are split into slices from a to something with some of the letters having special meanigns, for example

/dev/sd3c is the raw device of sd3 you would dd to if you were to flash an image to it

#

so even though they all descend from the same very basic things are still thought of vastly differntly

main olive Sep 28, 2019, 1:57 PM

#

eh, POSIX doesn't exactly dictate a device naming convention apart from some basic rules iirc

sage solar Sep 28, 2019, 1:57 PM

#

yeah

#

and sadly posix doesnt dictate tools like fdisk as well

#

so fdisk -l is gonna list partitions on linux, on OpenBSD its doing some block related things

#

posix doesnt seem to care much about hard disks in general tbh

main olive Sep 28, 2019, 2:02 PM

#

why are you working with bsd systems?

#

or what exactly is the nature of your job

#

if you don't mind me asking

it would be nice if the code for the product im currently working on wasnt a (with the exception of our modified openbsd and linux kernel) perl code base initially started in the 90s yes

although to be fair, maybe im a little biased, the featuer im working on touches our installer so its probably one of the oldest scripts on there

you basically just go to python.org, download the source tarball which should be somewhere in the downloads section, unpack it go into the directory you unpacked it into do a

./configure
# if you want to install your binary to a custom location, instead do a ./configure --prefix=/path/to/my/location

make
make test
sudo make install # for a custom location for example in your home directory sudo wont be necessary

and you are done

If u upgrade to Ubuntu mate 19, will I have to reinstall everything?

sage solar Sep 30, 2019, 12:28 PM

Nope, Ubuntu ist usually gonna trigger a mass rebuild for all their packages for the next version, then scream at the owners of whichever packages didn't build properly and when they don't get there in time do a release without them (which doesn't mean the owners can't still update it) so it's unlikely you'll run into any issues

(Well that's actually the fedora release process, I can't tell you exactly what Ubuntu does but I'd imagine theyd do it similar)

#

I'll be working with it, so I want to know what to expect

#

Well, technically, by naming this channel to #unix, we welcome all users of UNIX-like systems, including FreeBSD users and users of other open systems similar to Linux.

#

Generally, most of the hacks and tools on Linux are common to all POSIX systems, including Mac OSX.

So, I'm following RHEL8.0 134, and it asks to edit sysstat-collect.timer

#

problem: there is no sysstat-collect.timer

#

I've installed sysstat using yum install sysstat -y, as per exercise, but nothing.

#

I've even rebooted.

#

I can't do systemctl start sysstat-collect.timer because there isn't a file named that

#

what would be a noice distro for a 4gig i3-5005U nvidia 920M that kinda overheats?

#

rn I'm running fedora

sage solar Oct 1, 2019, 4:16 PM

#

We're running fedora on weaker workstations at work....well the older ones

#

The thing which makes it overheat right now is probably gnome

#

So uhm just look for another de or wm I guess
