I posted the following question to comp.unix.bsd.freebsd.misc and mailed it to questions@freebsd.org. Joerg Wunsch kindly responded and examined the log files (on both sides) during a connection. However, he suggested that I mail this to freebsd-hackers to see if I could find someone else interested in helping me resolve this problem. Note that the PPP server and the client are running FreeBSD 2.1R user-ppp. In my debugging session with Joerg, I also switched to the standard 'pppd' server. Same problems. Can anyone help me here? I'm forced to use Win95 (eiiik!) until I get this resolved. -Randy --- snip --- From: cfr@infoborg.dmacc.cc.ia.us (Charles F. Randall) Newsgroups: comp.unix.bsd.freebsd.misc Subject: Win95 & FreeBSD2.1R vs 2.1R user-PPP server Date: 11 May 1996 10:23:39 -0500 Message-ID: <4n2bdr$662@infoborg.dmacc.cc.ia.us> Reply-To: "Charles F. Randall" <crandall@dmacc.cc.ia.us> Background: At the time of the last FreeBSD 2.1 snap (fall 1995), I configured a 2.1-snap machine in my office as a user-ppp server. At the same time, I configured my dual-boot 2.0.5R/Win95 machine at home for PPP (with a static IP address) using the built-in dial-up networking for Win95 and user-ppp for FreeBSD. This worked just great (and I felt triumphant over a co-worker who has a $1200 Shiva Net modem for PPP in his office). I even documented the process and sent the results to doc@freebsd.org to be added to the FreeBSD Handbook (which doesn't cover a user-ppp server). Foreground(?): I decided to upgrade both the machines at work and at home to 2.1R. Diligently following my own instructions (and using the old configuration files as a second reference), I re-configured the user-PPP server at work and the user-ppp client at home. The server is configured for proxy arp and ip-forwarding. The Win95 client works. The FreeBSD client doesn't. Grr. The PPP link is established. Analyzing the ppp.log file on the server shows almost identical connections between the Win95 connection and the FreeBSD connection. Upon further investigation (scripts running on the server periodically checking things like arp entries, routing tables, etc.) everything seems to be configured correctly. However ... >From home, I try to ping the ppp server (always using IP addresses) and the send light on my modem flashes - nothing comes back. From the server, I try to ping my home machine and the recv light flashes - nothing is sent back. Using the same user-ppp client configuration , I can connect to my co-worker's Shiva Net-modem and everything works great. So much for that triumphant feeling. :^( The routing table on the FreeBSD client is the same when connected to either the Shiva Net-modem or the FreeBSD user-ppp server. So, did something in the proxy arp, ip-forwarding, or user-ppp code change between the last 2.1 snap and 2.1R? I'm going crazy trying to figure this out. Any suggestions would be greatly appreciated. I can provide extensive information to anyone willing to look at it. -Randy -- Charles F.
