My daughter has been going to UMCP for two years. The |dorms are wired for direct Network connections via 10-Base-T (RJ-45) He may not be in the dorms. Anyway, I've found that the way to debug a PPP connection is to disable all the optional features, and then enable them one at a time. I discovered that enabling lqr and/or predictor-1 compression with iijppp was a good way to foul a connection. If you connect to TIA or SLiRP instead of a real router, you can do just about anything a real connection can, and your network doesn't need to have valid IP addresses. I do this at home with iijppp->SLiRP. I have an internal IP network using one of the reserved class C addresses. I can telnet, ftp, web-surf, etc., from any machine on my network. Another advantage is that using SLiRP is at least as effective as using a firewall. The disadvantage is that SLiRP latency is higher that router latency on a loaded system. It also won't work for you if you need to provide internet access *to* your network (it can be done, but it's not pretty). - Tim Iverson iverson@lionheart.com
