[SOLVED] server.cfg: bind returned error: Address already in use

Stupid question number 1056:


The configurtaion file server.26001.cfg has this entry
port 26001 // the port used by the server

Start up gives this message.

Code:

Server using port 26000
LHNET_OpenSocket_Connectionless: bind returned error: Address already in use
Server failed to open socket on address 0.0.0.0:26000
Server listening on address 0.0.0.0:26001
LHNET_OpenSocket_Connectionless: bind returned error: Address already in use
Server failed to open socket on address [0:0:0:0:0:0:0:0]:26000
Server listening on address [0:0:0:0:0:0:0:0]:26001
Initializing ClientSide information entities
Error response from keygen server: Not allowed

I thought this was because the startup script parses the distribution server.cfg first and then applies the new server.cfg afterwards, so I removed the distribution server.cfg.

However the same message is displayed

Are you sure server.26001.cfg is executed at all? How do you launch the server?


Also, I edited your post title, as the default reply subject length was above threshold, which presented me with a not very user-friendly message that my subject was too long while I didn't type any.

With this modified startup script.

$ cat /usr/local/xonotic/server/server_linux.26001.sh

Code:

#!/bin/sh

case "$(uname -m)" in
  x86_64)    executable="xonotic-linux64-dedicated" ;;
  *)        executable="xonotic-linux32-dedicated" ;;
esac

cd "`dirname "${0}"`"

if ! [ -x "$executable" ]; then
    if [ -x "../$executable" ] && { [ -f ~/.xonotic/data/server.26001.cfg ] || [ -f ../data/server.cfg ]; }; then
        cd ..
    else
        echo "This script is not properly set up yet."
        echo "Please refer to the instructions in readme.txt."
        echo "In short:"
        echo "- copy server.cfg to the data directory and adjust its settings"
        echo "- move this file to the main directory of your Xonotic installation"
        exit 1
    fi
fi

exec ./${executable} -sessionid lock.26001  +serverconfig server.cfg "${@}"

Oh - I see the problem !!!!

Server is up.

Hehe

Interesting. Although it starts, I got this:

Code:

Note that port 26001 is not yet open on the firewall (still awaiting the firewall guy to make the change)

That output is fine.

Yet, the server still won't display in the list of available servers.
The ports are open:

If the server is public, why are you obfuscating its IP?

Have you tried querying the server directly using that url I showed you earlier?

Code:

http://dpmaster.deathmask.net/?game=xonotic&server=ip:port

I did not read the url you posted. Sorry. I was too quick.

Obfuscated purely out of habit. No need at all. Its public.

Seems like your firewall is still blocking it.

Oh. Groan. Missed this. I seem to be setting a trend here of skim reading and missing the obvious.

I hope they'll amend the f/w tomorrow.

I'm off to bed.
Night.
