Description gibbs 1995-04-01 15:30:01 UTC 
	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.

Fix: 

Make the install program disable these features during network 
	installations.
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.

State Changed
From-To: open->closed

As mentioned in the PR, this isn't a bug in FreeBSD and the decision on 
this is that TCP options negotiation should remain enabled.
