This one should be easy for you wizards, but it seems to elude me. I have installed RedHat 4.1 and updated the kernel to 2.0.27. The kernel was built with networking turned on as per instructions. I followed all the instructions in the kernel and Net-2/3 HOWTO files to the letter, but I am still unable to perform any net operations beyond pinging localhost.
When I try to ping or telnet to my own machine (which I have called jeh.linux.org), I get a message saying that the node is unreachable; this is the same message I get if I use DIP to try to establish a PPP connection to another host, so I am assuming that I have something set up wrong amongst all the /etc files. Ifconfig and route show only the local loopback.
My system is about as uncomplicated as you can get, networkwise. I have no Ethernet, and have enabled only TCP/IP in the kernel build (not IPX, Appletalk, ISDN, etc. etc). All I really need to do is to be able to establish PPP connections to my ISP (a university) and my employer, all of which I was able to do on Slackware 2.3 before I upgraded to RedHat 4.1.
What I would like is a succinct, step-by-nauseous-step guide to setting up the essential files to make this trivial setup work. What kernel build options do I need? Which /etc (and other) files need to contain what information about my system, routes, servers, gateways, networks, etc? Do I need to run any daemons besides inetd?
