Please fix. The problem is in jlemon's latest commit cleaning up the checksum calculations. I would be interested in seeing what netstat -s says for bad checksums.. I came up with this patch, which fixes my i386 machine.. I dont have an alpha to test. http://people.freebsd.org/~ps/cksum.diff -- Paul Saab Technical Yahoo [EMAIL PROTECTED] - [EMAIL PROTECTED] - [EMAIL PROTECTED] Do You .. uhh .. Yahoo!?

The same setup works today with kernel builded few hours before recent TCP changes. Nothing changed on my side excepting kernel and modules rebuilded from recent cvsup. -- Andrey A.

TCP becomes very broken just now
Some of recent kernel TCP changes cause TCP completely not working, i.e. any network daemon (mountd, sendmail, cfsd) started from "rc" on dialup machine hangs with 3min "Can't connect' timeout and user level "ppp" started than hangs forever even not dialing.
