Hi,
We had some problems that showed up to be caused by TCP options. Briefly:
Director:
ipvs: 0.2.5, 0.2.6 (tested with both)
kernel: 2.4.2
Real servers:
Kernels: 2.4.0-0.99.23smp, 2.2.16
Symptom:
TCP connections are not esatblished. The 3rd packet from the 3-way handshake
is rejected by Linux-based clients. Exactly the same configuration has been
used for tests, on a different network, and it didn't show up these symptoms.
The symptom diappears if all the following sysctl options are set to 0:
net.ipv4.tcp_timestamps, net.ipv4.tcp_sack, net.ipv4.tcp_window_scaling
Has anyone had similar symptoms ? Is there any reasonable explanation for
this ?
