Hardware

hi,

to prepair my project to run m0n0wall on a neoware box i have installed the compaq dual nic in my current m0n0wall box, an cyrix 250mhz box with 256ram and a laptop 1.2gb hd.

the neoware box only has 1 pci slot so i need a dual nic pci card to get 3 interfaces. this project is delayed since the orderd memory didn't came this saturday.

before this nic change this cyrix box had 3 realtek nic's, all working fine. running for weeks with 0/0 on the in/out errors status page. now with this compaq dual nic card i have already:

In/out errors      0/4 on the wan nic (compaq tl0)
In/out errors      36/5 on the dmz nic (compaq tl1)
In/out errors      0/0 on the lan nic (realtek rl0)

what can this be? all is connected with the same hardware / cables / switches / router...

the only thing what is changed is that i removed the 2 pci realtek nics and installed 1 compaq dual pci nic card. changed the drivers in the interfaces (assign) menu and of it went to work after a reboot.

What are your packet counts to go along with those error counts? Depending on what kind of a percentage you're seeing, I may or may not worry about them. Since it's the same cables and switch, it must be either a NIC problem, a driver problem, or maybe a duplex mismatch.

i was thinking that too. it's or a driver problem of the nic it self. i bought this nic on ebay...

on one of my 6513 i have this to compare...

in 105949207077 pkt, 10868101979878 bytes
out 188272898898 pkt, 50029770231137 bytes
0 input errors, 0 CRC, 0 frame, 24300 overrun, 0 ignored
0 output errors, 0 collisions, 1 interface reset.

the m0n0wall compaq nic:

WAN compaq nic
in/out packets      3118166/2866037 (1.35 GB/411.48 MB)
In/out errors    0/4
Collisions    0

LAN realtek nic
In/out packets      1608652/1883865 (175.88 MB/1.24 GB)
In/out errors    0/0
Collisions    0

DMZ compaq nic
In/out packets      2545171/2479337 (368.03 MB/231.63 MB)
In/out errors    96/5
Collisions    0

That's not nearly enough that I'd worry about it. That's like 0.004% and less. I wouldn't worry unless it was more like 100 times that high of a percentage.

Check the port speeds, you can get this if the switch is auto and cards are forced for example. They both should be set to either auto or forced.

No way is that a duplex mismatch as bdearlove suggested - you'd have very high error rates, likely 25% or higher depending on your network load, and serious performance problems.  Error rates of 0.004% and lower says it's definitely not a duplex mismatch.

0 collisions -> full duplex...
