      If its just the size of the file that's a problem can you possibly just
quota the log file's size?
Manage Log File size on
Ubuntu<http://www.watchingthenet.com/how-to-manage-log-file-size-archive-deletion.html>is
one writeup which gives a lot of detail on how to use LogRotate.
I think this is the Man page for
LogRotate<http://linuxcommand.org/man_pages/logrotate8.html>
.
If you are just trying to figure out how to reduce the number of messages
the above won't help.

Hi Mike,
my problem is solved. As I wrote in my first mail, I tired to connect
from the localhost to the localhost which did not work.
However, I have two more questions:
privileges? The browser plugin?

Is there a way to install the windows client without admin

x2goclient: I suppose no...
x2goplugin: should be possible (like any other ff plugin)
...

Is there a way to run the server admin GUI on gnome? I get the
message that kcontrol is missing. Although kdebase is installed.

since kde4 there is no more debian/ubuntu package called kcontrol. The
replacement of kcontrol in kde4 is called systemsettings (name of the
.deb package).
I am not sure enough if the admin GUIs will plug into systemsettings
in the same way as they do with kcontrol. If so, the developers might
provide a package update with the respective dependencies.
For you a work-around could be to provide a dummy kcontrol package
with equivs-build (check equivs package on Ubuntu/Debian), just to
satisfy dependencies in the x2go packages. However, this is untested...

Alex
Best,
Mike

Hi Paul,
on Tue May 26 11:40:43 CEST 2009 you had this request to the x2go-dev list:
...
Hello,
After installing X2go I see my auth.log is growing.
I see this:
May 25 06:53:22 server sudo:     root : TTY=unknown ; PWD=/ ; USER=root
; COMMAND=/usr/bin/x2gopgwrapper listsessionsroot server
May 25 06:53:22 server su[17628]: Successful su for postgres by root
May 25 06:53:22 server su[17628]: + ??? root:postgres
May 25 06:53:22 server su[17628]: pam_unix(su:session): session opened
for user postgres by (uid=0)
May 25 06:53:22 server su[17628]: pam_unix(su:session): session closed
for user postgres
May 25 06:53:23 server CRON[16311]: pam_unix(cron:session): session
closed for user root
May 25 06:53:28 server sudo:     root : TTY=unknown ; PWD=/ ; USER=root
; COMMAND=/usr/bin/x2gopgwrapper listsessionsroot server
(...)
I did a "/etc/init.d/x2goserver stop" and that helps.
And I can still login on the X2go server!
I see it is checking the database, but I don't understand why exactly.
Is it really necessary to do this every 5 seconds?
echo "select agent_pid, session_id, display, server, status,

to_char(init_time,'DD.MM.YY*HH24:MI:SS'),cookie,client,gr_port,

sound_port,to_char(last_time,'DD.MM.YY*HH24:MI:SS'),uname,

to_char(now()-init_time,'SSSS'),fs_port  from  sessions  

where server='$2'  order by status desc;"|psql -t x2go_sessions
;;
I saw you can change the sleep-time (5 seconds) in this script:
/usr/sbin/x2gocleansessions
but I am not sure this is a good idea...
With regards.
Paul van der Vlis.
have you already found a solution to this??? I experience the same
issue tried to look for a sudo hack to silence log file output but was
not successful...
Any ideas on this?
Greets,

The x2goserver daemon isn't actually the server; it starts the
x2gocleansessions daemon which cleans up after sessions in various
states every five seconds as you note below.  The actual connections to
the server are all driven from the client via ssh by calling various
scripts on the server.

I posted a description of what the various parts of X2Go do to the list
a while ago.  It included a discussion of the session cleanup process if
you would find that helpful.

We did not find a way to silence the logs and, in our case, it was even
worse because we were doing LDAP lookups every five seconds for the
postgres user.  However, we did consolidate to a single, centralized
database for all X2Go Servers.  We also created a single cleanup daemon
to clean up all X2Go Servers so that we didn't have hundreds of daemons
all running every five seconds.  We had the advantage that our X2Go
Servers were built on VServers to the cleanup up script has direct
access to the file systems on all the X2Go Servers.  The routine could
probably be easily hacked to provide the same access via SSH and use a
single cleanup daemon.  I posted the patches and documentation a while
ago.
I have some more changes to post which refine it but have not had the
time to document and post them.  If someone does have the time, the
patches should really be rewritten to be configurable options.  As I
posted them, they are a rip and replace patch - almost more of a fork
which is the last thing on Earth I want to do  . . . well . . . almost
the last thing ;-)  - John
