can ping only with sudo
lately i inadvertently did 'chmod 777 -R /dev' on my system (as root, of course!). now i find that to ping anyone i have to do it as sudo, else i get: ping: icmp open socket: Operation not permitted could the two things be connected? thanks, tom arnall -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

I attempted to run an strace (sometimes those can be useful to see what devices and files it is trying to read - look at access() and open() functions in particular) but I get the same error as you if I try to do an strace on ping. Otherwise, ping runs normally. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

Otherwise, ping runs normally. I believe this is because it won't run setuid under strace. As Tom says in the other reply, the OP's problem is most likely that /bin/ping has lost its setuid bit.
