Hi

 after scouring thru the list archives, I'm still no closer to solving my
problem - Im contiunually getting RX errors and TX overuns.

Her's my setup:
P-90
Linux 2.2.16
Driver version (err.... May 2000 ?)
2x Intel 100B adapters.
Running gated
about 10 "ipchains" rules 

Here's the output from ifconfig
[root@ug-gw /root]# /sbin/ifconfig -a
lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Bcast:127.255.255.255  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:3924  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0
          TX packets:0 errors:0 dropped:0 overruns:0

eth0      Link encap:10Mbps Ethernet  HWaddr 00:90:27:35:22:1A
          inet addr:XXX.XX.XXX.X  Bcast:XXX.XX.XXX.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:1068178 errors:2093 dropped:0 overruns:0
          TX packets:0 errors:0 dropped:0 overruns:185393
          Interrupt:12 Base address:0x2000 Memory:30-0

eth1      Link encap:10Mbps Ethernet  HWaddr 00:90:27:35:22:1D
          inet addr:XXX.XX.XXX.X  Bcast:XXX.XX.XXX.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:324341 errors:2421 dropped:0 overruns:0
          TX packets:0 errors:0 dropped:0 overruns:1099560
          Interrupt:11 Base address:0x4000 Memory:30-0

Ive tried tweaking values mention, like the packets/interrupt to 800, changed
the rx copy size to 20, and increased the FIFO buffers to 128.

Bandwidth testing with pings gives results of around 30-50Mbps (set to
100f/d), but a reasonable TCP transfer across max'es out at 2Mbps. THis is
fine for most cases, but Id still like to sort out these RX errors and TX
overruns. The TX packets entry from ifconfig NEVER budges from 0.

Any ideas?

Cheers,
Peter
