I have all the code, just need to get it working

vale narwhal Nov 27, 2022, 3:33 PM

#

expected? what did you expect?

#

why did you expect that?

tight chasm Nov 27, 2022, 3:50 PM

#

Hello @vale narwhal

#

I'm not sure honestly, I'm trying to figure it out

#

I'm trying to understand why I can't get it running

#

I compiled TalkClient.c, Retrieve.H and DieWithError.c into one file
and
I compiled TalkServer.c, Retrieve.H and DieWithError.c into another one
I'm getting that error when using it

vale narwhal Nov 27, 2022, 3:53 PM

#

does say 'it'. be specific.

tight chasm Nov 27, 2022, 3:56 PM

#

Sorry, I'm trying to understand how to use the client
I think I'm using it appropriately based upon syntax
When I enter
"./client 10.182.0.2 hello user1" on the client side,
I get
"----------------------------------------------------------------
Segmentation fault"

#

Would you be able to compile the files like I did, and see what you get on your end?

vale narwhal Nov 27, 2022, 3:59 PM

#

seg fault is a memory issue.. that's just bad coding. i thought you were ok coder, but just didn't read sendto() docs properly.

tight chasm Nov 27, 2022, 3:59 PM

#

Sorry, I guess my first issue is that I'm confused on the usage for the client
When I run it, and attempt to check it
it returns
"Usage: ./client <Server IP> <Echo Word> [<Echo Port>] <UserID> <TCP Port>"
So I'm not sure if I'm using it correctly

#

Can you tell me if I'm using it properly?

vale narwhal Nov 27, 2022, 4:01 PM

#

too much src. run it in debugger, and find the line that segfaults

tight chasm Nov 27, 2022, 4:02 PM

#

Do you mind if we go over the usage of client first?

vale narwhal Nov 27, 2022, 4:04 PM

#

i see piles of functions without error checking; nonsense statments like while(1), when while takes a bool expression. teh code needs to be completed first.

#

lots of un-init'd vars 😦

@tight chasm Has your question been resolved? If so, run !solved :)

@vale narwhal
The code is now working, however it is not working as intended
2 clients connected to the server are unable to communicate with each other

vale narwhal Nov 27, 2022, 4:59 PM

#

my internet is due to go offline in 30 sec for 1hr.

tight chasm Nov 27, 2022, 4:59 PM

#

ok

#

Can you help me later?

vale narwhal Nov 27, 2022, 5:00 PM

#

maybe.

#

you took code links away

tight chasm Nov 27, 2022, 5:00 PM

#

Oop, let me paste

#

https://srcb.in/fCqLFTy7ao - talk client
https://srcb.in/hN9X0NC64E - talk server
https://sourceb.in/ZPuECGsr64 - diewitherror
https://srcb.in/Kzn0R7dJMn - retrieve.h
compile TalkClient.c, Retrieve.H and DieWithError.c into one file (client)
compile TalkClient.c, Retrieve.H and DieWithError.c into one file (client)
compile TalkServer.c, Retrieve.H and DieWithError.c into another one(server)
run server in one ssh
run client in another ssh
run client in another ssh

error text suggests a misunderstanding of how TCP works

#

there is no "message"

#

there is only a stream of bytes.

#

sometimes 1, sometimes all of them

#

sometimes 1/2 of them, then a delay, then the other 1/2 in the next call

tight chasm Nov 27, 2022, 5:04 PM

#

I'm not getting an error though...

vale narwhal Nov 27, 2022, 5:05 PM

#

probably only by chance

tight chasm Nov 27, 2022, 5:05 PM

You're not very helpful

Hi

pine loom Nov 27, 2022, 5:15 PM

#

Don't you dare telling someone "You're not very helpful" just because you're dissatisfied with their resolve.

tight chasm Nov 27, 2022, 5:15 PM

#

Hello, can I please have some help?

bronze dirge Nov 27, 2022, 5:15 PM

#

At this point please ask a new question.

tight chasm Nov 27, 2022, 5:15 PM

ShadowDragon is being mean

#

Ok

Firstly, don't ping moderators because you aren't happy with the help you were given

tight chasm Nov 27, 2022, 5:16 PM

#

No, it wasn't that
I felt attacked

bronze dirge Nov 27, 2022, 5:16 PM

#

tight chasm ShadowDragon is being mean

He was not really out of line.

barren dome Nov 27, 2022, 5:16 PM

#

You're not being attacked, but you aren't helping yourself get helped either

#

Read the snippet above on how to ask a good question

tight chasm Nov 27, 2022, 5:16 PM

#

Sure thing

bronze dirge Nov 27, 2022, 5:16 PM

#

And please be patient with people trying to help

tight chasm Nov 27, 2022, 5:18 PM

#

I felt like his remarks were mean and out of line, but my apologies
I asked for help and he just verbally assults me, is how I felt

barren dome Nov 27, 2022, 5:18 PM

#

I mean, you're the first one that started throwing out-of-line comments

#

"You're not very helpful" and "!NOTRESOLVED"

pine loom Nov 27, 2022, 5:18 PM

#

People can feel whatever they want. If you're one of the unfortunate "minorities", this place is not for you, a narcissist.

tight chasm Nov 27, 2022, 5:19 PM

#

This is what I meant

barren dome Nov 27, 2022, 5:19 PM

#

Calling people narcissists is also out of line

bronze dirge Nov 27, 2022, 5:19 PM

#

Not sure what minorities have to do with anything here
