Thanks in advance. rfc1323 is supported, and is enabled by default. Edit /etc/rc.conf and set tcp_extensions="YES"to make sure. Luigi Rizzo has patches to enable SACK on 2.1.0 at http://www.iet.unipi.it/~luigi/sack.html. I updated his patches to work on 2.2 and 3.0. The 2.2 patches apply cleanly to 2.2.8 (I emailed them to soemone who says they work). 3.* has changed enough that my patches no longer apply cleanly to 3.2. -Dan Nelson dnelson@emsphone.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
