Try this: + + 12. I'm using sPPP. I can connect to my ISP but no TCP/IP services work. HELP! + ============================================================================== + + This is probably because you have the RFC1323 - TCP Extensions for High + Performance - support turned on and your ISP (or some router in the loop) + is discarding the extensions. + + This can easily be checked by doing ``sysctl net.inet.tcp.rfc1323''. If the + result is 1, then the RFC1323 support is turned on. + + Turn this off by doing ``sysctl -w net.inet.tcp.rfc1323=0''. + + For FreeBSD make sure that tcp_extension="NO" is in your /etc/rc.conf + (/etc/defaults/rc.conf with more recent versions of FreeBSD) !! --- Gary Jennejohn Home - garyj@muc.de Work - garyj@fkr.dec.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
