So the real question is: how can you manage so that not everything in /proc is world-readable (is that´s possible by design)? [waldner:~] ls -al /proc/ dr-xr-xr-x 3 root root 0 May 16 21:05 1 dr-xr-xr-x 3 root root 0 May 16 21:05 16 dr-xr-xr-x 3 waldner users 0 May 16 21:10 1779 ... [waldner:~] ls -la /proc/1/ dr-xr-xr-x 3 root root 0 May 16 21:05 . dr-xr-xr-x 5 root root 0 May 16 20:10 .. -r--r--r-- 1 root root 0 May 16 21:11 cmdline ... Does really every process have to know about each others commandline? I would´ve imagined that the perms in /proc would depend on the perms of the executed program, but: [waldner:~] ls -la setiathome -rwx------ 1 waldner waldner 328608 Jan 23 20:31 setiathome [waldner:~] pidof ./setiathome 1909 [root:~] su - tina $ ls -la /proc/1909/ dr-xr-xr-x 3 waldner users 0 May 16 21:18 . dr-xr-xr-x 5 root root 0 May 16 20:10 .. -r--r--r-- 1 waldner users 0 May 16 21:18 cmdline ... $ cat !$cmdline cat /proc/1909/cmdline ./setiathome-nice19 Or is there an error in my logic? (I think I´m gonna be more careful now when running something on servers with lots o´ accounts...) &rw -- / Robert Waldner <[EMAIL PROTECTED]> | Phone: +43 1 89933 0 Fax x533 \ \ KPNQwest/AT tech staff | Diefenbachg. 35 A-1150 Wien /
