Hi. I was referred to this forum from MandrakeLinux for its "friendliness and eagerness to help." We'll see. I am attempting to teach myself some linux networking. I have two identical machines, with identical NICs, connected via a known good crossover cable, both machines running Mandrake 9.2. I was able to initially configure each NIC with a static IP address and netmask. One of the machines has a dialup modem which is working. I was able to ping each machine from the other as well as the ppp0 interface. However, when I did ssh, connection was refused. The mandrake config tool indicated both ethernet interfaces were "up." I used the Mandrake configuration tool to share out the dialup modem internet connection. Now I cannot ping either machine. The one machine with the dialup modem can still dialup and connect to the internet and I can browse web sites. I am having a hard time sorting out default gateways and gateways. What IP address should I assign as the gateway (default gateway?) on the internal machine? What IP address should I assign as the gateway (defaulty gateway?) on the other machine? I appreciate your replies.
