I have encountered a possible bug in the implementation of the PPP on FreeBSD 2.0, both the "RELEASE", and in all of the following snapshots, including 950210. The problem can best be described as a failure of the PPP link, but only when certain network applications are executed. The best repeatable examples that I have noted are during FTP sessions to "ftp.mcom.com", and during the startup of IRC-II. The modem connection is usually lost as well. There are never any error messages reported, either to the console, or to /var/log/messages. The only possible way to resolve the problem is to kill pppd, and then restart it, assuming that the connection is not lost. SLIP works fine. The command line used to invoke pppd was: pppd crtscts defaultroute /dev/cuaa0 57600 The connection is made to my employer's network. We use Xylogics Micro-Annex terminal servers, equipped with both SLIP and PPP. I have attached my machine's configuation data, as well as a copy of the my kernel configuration file for the 950210 snapshot. I would appreciate any advice on how to resolve the problem. ( It's actually not a huge problem, but I'd like to have a working PPP ) Other than this, the latest snapshot appears to be more stable than any of the previous. The only other bug that I know of involves non-working menus in some of the simple apps such as "xman" that are included with X. ( I'm assuming that this is probably a bug in the Athena Widget Set that is included with XFree86 3.1.1 ) Finally, I would like to thank the entire FreeBSD development team for producing such a great OS.
