[X2Go-User] Change TMPDIR from /tmp to /app

[Sherry Leithner]

x2go creates large files in /tmp/.x2go-username when a session is saved. This is causing us difficulty because /tmp is filling up and no users can log in. Our /tmp directory is too small and I don't have access to increase it. We need to change the default tmp directory from /tmp to /app.

I have set TMPDIR in my .profile, /etc/profile and also in /etc/x2go/Xsession to /app

.profile
 export TMPDIR=/app/

Xsession variables

initialize variables for use by all session scripts
OPTIONFILE=/etc/x2go/Xsession.options

SYSRESOURCES=/etc/x2go/Xresources

USRRESOURCES=$HOME/.Xresources-x2go

SYSSESSIONDIR=/etc/x2go/Xsession.d

USERXSESSION=$HOME/.xsession-x2go

USERXSESSIONRC=$HOME/.xsessionrc-x2go

ALTUSERXSESSION=$HOME/.Xsession-x2go

ERRFILE="${HOME}/.xsession-x2go-${cur_hostname}-errors"

TMPDIR=/app

The session still creates the tmp files in /tmp

The x2go process which is running:

leithner 16137 1 0 11:23 ? 00:00:00 sshfs -o idmap=user,uid=1007,gid=1001,default_permissions,ServerAliveInterval=300,IdentityFile=/home/leithner/.x2go/ssh/key.p14092,UserKnownHostsFile=/home/leithner/.x2go/ssh/key.p14092.ident SLeithne at 127.0.0.1:/cygdrive/C/Users/SLeithne/X2GO~1/S-2E61~1/spool /tmp/.x2go-leithner/spool/C-leithner-50-1643045018_stDXFCE_dp32 -p 50660

leithner at entrada:/app$ echo $TMPDIR
 /app

Where should I be changing this variable? Can it be changed?

Thank you for any help.
