Internet's fine but can't ping!
I recently noticed that I couldn't send out emails from Evolution via either Smtp or sendmail. I used PING and traceroute to check the network and no trace or packet gets sent. Even on the localhost. Retracing my steps, I found this started occuring when I set my Linux box to activate internet connection at boot up to allow my non-root users access to the net.
I googled on this and even found this useful Network troubleshooting HOW-TO but don't know how to proceed from there. http://ubuntuforums.org/showthread.php?t=25557
So internet works, can receive emails but cannot send or ping any site local or otherwise.
Network gurus: any help would be appreciated
