NX> 1004 Error: NX Agent exited with exit status 1.
Note to self — Always have the selinux troubleshooter running. It's invaluable when random applications fail to start. F.ex. I was struggeling trying to get FreeNX running on a RHEL5 system. It was simply complaining:
NX> 1004 Error: NX Agent exited with exit status 1.
and after a while I found these in the audit.log:
type=AVC msg=audit(1185437241.015:6449): avc: denied { execmod } for pid=17465 comm="nxagent" name="libXcomp.so.2" dev=dm-0 ino=1509560 scontext=user_u:system_r:unconfined_t:s0 tcontext=system_u:object_r:lib_t:s0 tclass=file
type=AVC_PATH msg=audit(1185437241.015:6449): path="/usr/lib/nx/libXcomp.so.2"
The troubleshooter would have alerted me immediately, if I had been running it.. Instead I wasted time thinking this was a problem with me not knowing how to set up NX. The workaround was of course to label the libXcomp.so-libraries as textrel_shlib_t:
# semanage fcontext -a -t textrel_shlib_t "/usr/lib/nx/libXcomp.so(.*)" # restorecon /usr/lib/nx/libXcomp.so.2*
