Just in case anyone is interested, one way I found to squeeze a few more bytes through your SLIP link is to set "tcp_extensions=NO" in your /etc/sysconfig file. This disables the RFC1323 & RFC1644 extensions, which are really intended for high speed links. In fact, RFC1323 even suggests disabling it on slow links. If you don't normally connect to other hosts that support RFC1323 and RFC1644 then you won't see any difference. To determine if a host you are connecting to supports RFC1323, try examining some traffic to/from that machine with "tcpdump". If it indicates that the "timestamp" option was present, then it is sending the extra RFC1323 data. -- Mike Pritchard pritc003@maroon.tc.umn.edu "Go that way. Really fast.
