Re: ping: Operation not permitted
Is your ethernet 0's IP 192.168.1.1? If so, you have a default gateway of yourself... I don't thing that will work?

It sure does. What's the output of '/sbin/ifconfig eth0'? Kevin Traas wrote: I'm doing this as root. Does that make a difference? Later, Kevin On Mon, 18 May 1998, Jens B.

Re: ping: Operation not permitted
Sounds like more setuid trouble. To send an ICMP packet (ping uses the ICMP ECHO-REQUEST) you need a raw socket. Only root can create a raw socket. For this reason ping must be setuid root.
