If you were given the information by your hosting provider, verify that it's correct compared to what you have in /etc/rc.conf Where did you get your IP addy? You should have been provided a netmask in the same document/conversation/whatever. Also, based on some other replies to this thread, could you post your /etc/rc.conf to the list. It may help sort out what's up. Background: netmasks of ffffffff (i.e. 255.255.255.255) are normally used only for 1) point-to-point connections 2) IP aliases (when a NIC has more than 1 IP addy) Using it on a broadcast NIC (such as ethernet) pretty much ensures that no networking will go nowhere. Basically, you're telling the IP software that the only IP that can be reached via that card is the one the card already has: thus the routing software can't determine where to send packets. Another thing you can do is simply change it to 255.255.255.0 and see if things start to work. It's possible that that number is wrong, but it will break _less_ networking than using 255.255.255.255, so you'll be able to tell if you're on the right track or not: ifconfig fxp0 netmask 255.255.255.0 -- Bill Moran Potential Technologies http://www.potentialtech.com
