I currently experience network problem. I run FreeBSD 4.6.2 with ipfilter
3.4.27 with 5 ethernet interfaces (all 3C905). I think we have a problem
with a card xl0. It have 43698 inputs packets with 2424 input errors
packets. I think this is problem with ethernet packets (probably checksum
errors) ?
I plan to change the card tonight. Does anybody experience this kind of
problems ?
Another question, does the total of packets (<Link#1>) should match the
total packets of each ip alias ? If it's not the case, the difference of
packets aren't for IP protocol ?
Thanks
