Hi guys,
Is there a case for keeping
tcp_extensions="NO"
in /etc/defaults/rc.conf, or are the vast majority of other systems able
to deal with it now?
[ Background -- NetCraft, the server statistics people, are about to start
producing reports where they figure out the uptime of the server's they're
talking to. I was talking to one of their engineers yesterday, and he
mentioned that FreeBSD doesn't work well with this, because most of the
deployed systems keep tcp_extensions turned off, and they use the RFC1323
extensions to do the report. Obviously, if it's still an issue then we
should keep them turned off (and probably prepare some sort of text that
NetCraft can send out with the reports which explains why FreeBSD doesn't
figure very well in the report. Alternatively, if it's not a problem
any more then we should turn them on. ]
