[Mumble] Issue with multihomed server interfaces

[ncronin]

I can't seem to figure this out, I've tried many different ports (and ips) and isolating it to it's own user but it doesn't seem to want to start on the specified port. Any help would be greatly appreciated! ♥

Error: [ FAIL ] Starting mumble-server: Unable to start Mumble Port 64738

I am using a single user because I'm a horrible person. There's 1 rust, 11 TF2, 6 CS:GO, and 6 CS:S servers on this machine all running LGSM on their own IP w/ default port.

Usually when a port doesn't bind, it's due to the port being already in use (which you say isn't the case), or the IP address not being bound to the machine (198.27.120.24 bound to an interface). Have you double-checked the IP address?

If that's not the case, push your murmur.ini to pastbin (strip any credentials), along with the results of ./mumbleserver debug. Additionally, post the output of netstat -atunp | grep murmur and make sure that your IP address is listed in ifconfig -a | grep "inet " | awk '{print $2}'.

murmur.ini: http://pastebin.com/gvK4bdSQ

Output of netstat:

tcp        0      0 198.27.120.24:64738     0.0.0.0:*               LISTEN      29303/murmur.x86

IP addresses are definitely listed.

Debug output?

[ncronin]

Got this error when running the command:

./server debug
Unknown command: ./server debug
Usage: ./server [option]
Mumble - Linux Game Server Manager - Version 290716
https://gameservermanagers.com/server

[cedarlug]

Is process 29303 a rogue process? If so, kill it with kill -9 290303 and see if mumble would start.

(./mumbleserver debug) Edit: Ah - no debug for mumble. Gotcha

[cedarlug]

Follow-up: Your mumble server is running (I've connected to it). So it may be misreporting by the "details" output as being OFFLINE.

What happens when you kill the murmur process (above), re-examine netstat (seeing NO murmur process), and restart the mumble server. If the details output still shows it as offline then there may be a bug with the process detection in the script.

[ncronin]

That's very odd. It does seem like the script misreporting it. I also would like to add that the script requires you to add ip="" in mumbleserver or else it throws an error. This isn't required though as it's set in murmur.ini

Seems to be working nonetheless so I'll wait for a bugfix and continue on, thanks! :)

[UltimateByte]

Huh, i'll need to gett back into it. Unless you solve it before... I had it working 100% like 2-3 weks ago, but many commits happened since.

[cedarlug]

This appears to be an issue which pops up when there are multiple IP addresses on the server.

There are some options here as to what the correct behavior is.

• Option A is to allow the default mumble behavior - listen on 0.0.0.0 and change check_ip.sh to ignore mumble (just as it ignores TeamSpeak)
• Option B is to force "host=" (not ip=) to be set in murmur.ini to be one of the IP addresses on the server, and to change check_ip.sh to honor the "host=" setting of murmur.
• Option C is something other than the above which I might not be considering.

Thoughts?

[jach11]

Most users will probably expect IP addressing to be set within the script if they already use lgsm for other servers. I think for the sake of consistency it should be set within the script and just ignore mumble.

[UltimateByte]

Well, it's working OK for me with one interface. I'm worried about warnings about libstdc packages that i need to make go away.

We need to ignore it through check_ip.sh first, then see if it's fixed. Can't really test as i got only one interface and won't bother simulating a virtual interface or something.

So https://github.com/GameServerManagers/LinuxGSM/blob/master/lgsm/functions/check_ip.sh#L11

if [ "${gamename}" != "TeamSpeak 3" ]&&[ "${gamename}" != "Mumble" ]; then

Can you test it out already ?

[cedarlug]

Yes - that fixes the issue on a multihomed system with the exception of the details output printing out a fixed IP when it's listening on 0.0.0.0.

Pushed to master.

[cedarlug]

@jach11 What you're suggesting is problematic because murmur doesn't accept IP specifications on the command line, only from the ini file. So there's not a good way to pass it from the lgsm script other than to pre-process the ini file (with a quick "sed -i "s/host=.*/host=${ip}/" ${inifile}) before invoking the murmur.x86 binary.

[jach11]

Ah i see that now, and by the looks of how they already have everything setup they won't ever change that, which kind of sucks.

[dgibbs64]

@jach11 Yes it can be difficult to keep thinks consistent when all the servers work differently :P. Over all LGSM manages to do that though :)

[UltimateByte]

Alright, i guess it's solved ? Close ? Or we try to improve the details output when no IP is set too ?

[cedarlug]

Closing. Revisit the details output separately.

[ncronin]

Sorry to bump, while the script works and starts the server fine. The error "cannot bind to port {whatever port is set}" still appears.

This is fine but in order to stop or restart the server you need to kill the process.

[cedarlug]

@ncronin - can you give a bit more details? Is this after the "./mumbleserver stop" or "./mumbleserver restart"? Where is the server process not being killed correctly?

[UltimateByte]

Yeah, and where does that error occur ? What log / command ?

[UltimateByte]

Is this still a thing ? @ncronin

[dgibbs64]

I believe the addition of graceful shutdown to most servers may of resolved this issue.
