This sounds very much like an MTU issue. Perhaps something with path MTU discovery changed? I would try disabling it (echo 1 > /proc/net/sys/ipv4/ip_no_pmtu_disc, I believe) or lowering your interface MTU (ifconfig eth0 mtu 1400). This causes TCP to advertise a lower mss. I did try verifying the MTU path to www.usenix.org, and it's clean until the handoff from MCI. In your traffic dumps, were the MSS's advertised with FC1 and FC2 the same? -Kevin -- TriLUG mailing list : http://www.trilug.org/mailman/listinfo/trilug TriLUG Organizational FAQ : http://trilug.org/faq/ TriLUG Member Services FAQ : http://members.trilug.org/services_faq/ TriLUG PGP Keyring : http://trilug.org/~chrish/trilug.asc
