If you use SuSE and you care a _lot_ about local security you must edit /etc/rc.config and set PERMISSION_SECURITY="paranoid". That way gnuplot would _not_ be suidroot. See the contents of /etc/permissions.paranoid: root@laser:/home/andrea# grep gnuplot /etc/permissions.paranoid # WHY ON HELL was gnuplot suid root !!!!! /usr/bin/gnuplot root.root 755 Using PERMISSION_SECURITY="secure" was just installing tvscreen _not_ suidroot. Using PERMISSION_SECURITY="easy" (and note: you are asked to set "easy" instead of "secure") is very riskious in a envinronment that has to be secured, but you asked for that so don't complain (e.g. about xtvscreen). I just tried once to fix the disinformation on the list about SuSE xtvscreen suidroot but Aleph One didn't accepted my email. I don't know why Aleph One didn't accepted my first email. Aleph?
