Sounds like a bad routing table. Like the resolve file is set right but the return route for the packets is bad. Had something similar with a win2k box and Pcanywhere. It would receive the first packet but couldn't return them.

Addresses that work: www.google.com www.is.co.za www.anazi.co.za Addresses that do not work: www.yahoo.com www.apple.com An attempt to resolve the packet looks like this: [EMAIL PROTECTED] root]# dig www.yahoo.com @196.4.160.2 ; <<>> DiG 9.2.1 <<>> www.yahoo.com @196.4.160.2 ;; global options: printcmd ;; connection timed out; no servers could be reached When tcpdump is used to sniff the connection, the following is shown: 14:21:55.641265 168.209.124.18.32839 > 196.4.160.2.domain: 57497+ A? www.yahoo.com. (31) (DF) 14:22:00.653797 168.209.124.18.32839 > 196.4.160.2.domain: 57497+ A? www.yahoo.com. (31) (DF) Two packets go out, nothing comes back. When the next hop router is sniffed, it shows the packets go out, and it shows packets being returned - the Linux box (or something) is dropping the return packets before they reach tcpdump. Anyone seen anything like this before?
