Networking :: Notebook dialup

I successfully logged onto my dialup internet server from my Fujutsu notebook 790Tx's modem using a live DSL 3.3 CD, but Firefox and other internet protocols were unable to recognize internet addresses, only ip numbers. During the dialup I got two suspicious messages, "Jul 16 22:40:02 box local2.warn pppd[1353]: Unsupported protocol 0x8207 received" and "Jul 16 22:40:02 box local2.err pppd[1353]: Cannot determine ethernet address for proxy ARP". I don't know if these messages are related to the problem. The same dialup server worked properly when tested from a desktop PC using a KNOPPIX live CD (which required more RAM than was available on the laptop). Any suggestions?

The first error means your company tried to talk with Cisco Discovery Protocol. It's harmless.

Were you assigned DNS server addresses?

DNS is usually supplied by your ISP during the dial up exchange.
If not, you can manually add them to /etc/resolv.conf and then add that file to your backup.
