[gentoo-user] high packet loss

[gentoo-user] high packet loss

[Eray Aslan]

Hello,

I wanted to change the router/firewall at a small office lan to hardened
gentoo.  The machine in question sits between a consumer grade adsl modem
and 3 different networks (so a total of 4 eth cards on the server).

However, there is a high packet loss (25-50%) between server and adsl
modem.  cat /proc/net/dev reveals high error count on the receive side of
the eth card connected to modem (transmit side has no errors).  I changed
the eth card and the network cable but the problem stays the same.

The same eth card and cable works without any errors with a FC3 server.  I
am beginning to think that the errors are because of a faulty (on my part)
sofware config.

I am out of ideas to try.  Any pointers to possible causes of high packet
loss are highly appreciated.

Thank you

I had something like this a while back, it turned out it was the dsl modem
was picking up RF interference from a dimmer switch.
If the light was full on or full off it was fine, but anywhere in between
and it dropped packets like crazy. I added a choke on the lamp's power line
and it's been fine since. YMMV.
