Yeah, I gave strace another shot and this time I got what I needed: 4513 getppid() = 1 4513 readlink("/proc/1/exe", 0xbf824ddc, 512) = -1 EACCES (Permission denied) A grep after getppid in the sources of pidgin showed me the line of interest ;-) Thanks Michal and Stephen for your suggestions. cheers, Stefan -- This message was distributed to subscribers of the selinux mailing list.
