I can have 50-60 users logged on via x2go. Sometimes I need to logout many users. I use the following utility to list and match x2go sessions.
Using the -r switch will run x2goterminate-session against the matched sessions.
Others may find this useful, so I post my script here.
Running the script without arguments will simply list all x2go sessions.
The -h switch will show usage.
I've attached the file but I suspect that will it be lost in the mailing list archives.
Since it's short I also cut and paste here:
------------------------------ cut ------------------------------ #!/usr/bin/perl # List (and terminate) x2go sessions use strict; use warnings; use v5.10; use Getopt::Std;
my %opts; getopts('hjqr', \%opts); my $help = defined $opts{h} ? $opts{h} : 0; my $printjob = defined $opts{j} ? $opts{j} : 0; my $quite = defined $opts{q} ? $opts{q} : 0; my $run = defined $opts{r} ? $opts{r} : 0;
my $x2goterminate = '/usr/bin/x2goterminate-session'; my $x2golistsessions = '/usr/sbin/x2golistsessions_root';
if ($help) { print STDERR <<EOT; Usage: $0 [-hjqr] [[pattern] .. pattern] Runs $x2golistsessions and outputs in a more readable format Only print x2go sessions that match the pattern[s] If no pattern is given, lists all x2go sessions -h This message -j print job command to terminate matched sessions, not session information -q quite, don't print anything -r Terminate the matched sessions with $x2goterminate EOT exit 1; }
