Original GitHub issue: https://github.com/GameServerManagers/LinuxGSM/issues/487

Running fresh Ubuntu 14.04 in a VPS.
Have done apt update and upgrade.

Error

create session failed: ./srcds_linux -game insurgency -strictportbind -ip HIDDENIP -port 27015 +clientport 27005 +tv_port 27020 +map ministry +servercfgfile ins- server.cfg -maxplayers 16: No such file or directory

I have the latest insserver lgsm from github. There seem to be some problems with certificates at the moment affecting the script install but I have added --no-check-certificate in the relevant wget parts.

I initially had the tmux user not in group problem but rant he command usermod -G tty insserver and now get tty❌5:insserver.

Everything seems to be installed fine but it wont start as No such file or directory.

Installed to default /home/insserver

I think there is something wrong with tmux.
If I type tmux as insserver user I get:

insserver@zzgg:$ tmux
insserver@zzgg:$ 6c

So it prints 6c as if I had typed it myself.

If I do it as root I get the normal tmux screen with a green bar.

I've updated to tmux 2.0 via the ppa with no result (clutching at straws...)

SOLVED:

Ok so it turns out there can be a number of problems that cause this issue. Basically Google "unable to run tmux as user other than root" or something similar for a good starting point.

The best way to find the problem is:

strace -f -e trace=file tmux

Then look for errors that say permission denied / no such file or directory errors right before it exits.

In my case I had the following:
[pid 512] open("/dev/ptmx", O_RDWR) = -1 EACCES (Permission denied)
[pid 512] open("/dev/ptyp0", O_RDWR) = -1 ENOENT (No such file or directory)
+++ exited with 0 +++

I compared the permissions on /dev/ptmx from my KVM VPS to this OVZ VPS.

KVM was 666
OVZ was 600

I chmod the OVZ /dev/ptmx to 666.

tmux now worked perfectly and I could start the server.

I'm told this is the standard default configuration for OVZ VPS servers.
