>Release:        FreeBSD 2.1.0-Development i386
>Environment:

	SLIP connection to an annex (and possibly other) terminal server.
	VJ header compression might be a factor.

>Description:

	rfc1323 and rfc1644 negotiation can make TCP communication to other
	FreeBSD machines on the other side of a SLIP link impossible.  This
	is not a FreeBSD bug, but a bug in many terminal servers.

	During install, I would highly recommend that these two commands be
	run before any type of network installation:

	sysctl -w net.inet.tcp.rfc1323=0
	sysctl -w net.inet.tcp.rfc1644=0

	It would not look good to not be able to ftp the distribution from
	one of our own machines.  There should also be a big warning about
	this in the install notes and possibly even during installation.

>How-To-Repeat:

	If you want to see it in action, just let me know, and I'll turn
	rfc1323 and rfc1644 negotiation back on for narnia.hip.berkeley.edu.

>Fix:
	
	Make the install program disable these features during network 
	installations.
