You're going to need to provide output from the following, run as root. For the pciconf command, please only include the entry that's relevant to the device in question (em2). You can also XXX-out the MAC address and/or IP addresses if you're worried about security. $ pciconf -lvc $ dmesg | grep em2 $ sysctl dev.em.2 $ uname -a $ netstat -ind -I em2 Thanks. -- | Jeremy Chadwick jdc@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
