Hi everyone, When using Slackware 4.0 (kernel 2.2.12) I had a C program like: -----change_route.c---- #include <stdlib.h> main (void){ system("/sbin/route del default"); system("/sbin/route add default gw 1.1.1.1"); } ----------------------- compiled, and suid root, any user could run it... On Slackware 7.1 (kernel 2.2.16), it gives me: SIOCDELRT: Operation not permitted SIOCADDRT: Operation not permitted when I try to run it as a simple user, even if the program has the same permissions as before (-rwsr-sr-x 1 root staff). Any ideas? bogdan - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.linux-learn.org/faqs
