I am using the 3Com Etherlink III Combo ethernet cards. I configured the cards with the 3Com utility as described in the mailing list archive. I have my pentium tower set up as a gateway and a 486 tower as a host (Using 10.0.1.x for IP addresses). The following files were set up: - /etc/hosts - /etc/host.conf - /etc/rc.conf - /etc/resolv.conf Here's the problem. I am running tcpdump on the pentium system to view traffic on the interface (unfortunately I can't run tcpdump from the 486 until I can recompile a new kernel). I can attempt to ping the pentium from the 486 and no traffic shows up on tcpdump. Pinging from the pentium to the 486 does show the ICMP echo requests but the 486 doesn't answer. I then can attempt to ftp or telnet from the 486 to the pentium and I *do* see a few exchanges on the interface via tcpdump. I can get as far as a login prompt and password but then it just hangs and eventually times out. Telnet and ftp from the pentium to the 486 both get the connected message but then hang before the login prompt. Sometimes I don't even see the connected message. The /etc files are set up correctly above because a co-worker took the 486 tower home last night, hooked it up to his network and it worked correctly the first time. The routing tables are correct when I do a "netstat -rn" on both machines and "ifconfig -a" shows that the interface is up. I don't understand why ping requests from the 486 don't show up at all. I would greatly appreciate any help you could give me. Thanks! Jeff Henning jeh@anubis.network.com
