ok ... what cant you do then?
you shouldnt have to worry about permissions to a nic. more likely you have 'bad' permissions to your programs. when are you getting this problem?
netscape, galeon, gaim, ftp?
try "ncftp carroll.cac.psu.edu" from the console if you get ncftp: command not found try "ftp carroll.cac.psu.edu" and see if you get a connection. if you do then its the permissions on the programs you are trying to use if not .... ummm Are you behind a firewall?
