[Planetlab-users] Large number of network errors

[Bowman, M. <mic...@in...>]

All,

We've been noticing on some machines with e100 and e1000 cards that the
full/half duplex negotiation is incorrect. In particular, we have
documented several cases where the Dell 650 e1000 card is running half
duplex connection to a full duplex switch. The result is a large number
of errors and collisions on a connection that should have none. We're
going to look for a fix. Does anyone know of a good programmatic test to
determine if the settings are correct/optimum?

In the meantime, I thought I would at least publish the list of nodes
with the number of network errors (as reported in /proc/net/dev). This
is not measured against uptime so variance is expected.
