direct links of old sources may well be a few messages off.


if I were you I would first test my network conection on intensive traffic.

Try using IPERF (http://dast.nlanr.net/Projects/Iperf/). Start iperf
with "iperf -s" at the first node a them "iperf -c node1 -s 30" on the
second. If everything goes OK, them increase the test time (-s 30 = 30

This will tell you if your having any problems with the
driver/kernel/NIC/cable systems. You could also check your firewall
rules for any climit/limit rule.

Best regards,
Daniel Colchete
