Hello, |
2 |
I'm quite desperate and have tried just about anything. |
3 |
I'll try to explain it... |
4 |
|
5 |
I connect to the net through eth0 and have a masquerading through eth1 |
6 |
to my other computers, using shorewall. |
7 |
My server never had any problems of this kind and all was fine until a |
8 |
couple of days ago. I'm experiencing some heavy packet loss when |
9 |
pinging different hosts. |
10 |
I have isolated the problem (at least I think I did) and got to the |
11 |
conclusion that issuing a simple 'ifconfig eth1 down' and leaving eth0 |
12 |
up, the packet loss vanishes. |
13 |
Tests were made with all services down (shorewall, sshd, apache2, |
14 |
mysqld, proftpd, sendmail, ...) and with the network cable unplugged |
15 |
from eth1 (so no traffic is being generated through eth1 that could |
16 |
cause packet loss) |
17 |
Here are the statistics: |
18 |
|
19 |
- eth1 up - |
20 |
# ping -c 200 google.com |
21 |
|
22 |
--- google.com ping statistics --- |
23 |
200 packets transmitted, 104 received, 48% packet loss, time 208227ms |
24 |
rtt min/avg/max/mdev = 152.388/229.520/2016.847/279.805 ms, pipe 3 |
25 |
|
26 |
- eth1 down - |
27 |
# ping -c 200 google.com |
28 |
|
29 |
--- google.com ping statistics --- |
30 |
200 packets transmitted, 200 received, 0% packet loss, time 199175ms |
31 |
rtt min/avg/max/mdev = 147.197/169.978/193.949/8.384 ms |
32 |
|
33 |
Both network cards are using the same chipset (RLT8139) loaded as a |
34 |
module in the kernel (2.6.11-hardened-r13). |
35 |
I have tried to replace the network card (with one also using RLT8139) |
36 |
and changing it from IRQ but with no effect. |
37 |
Please help, I've runned out of ideas... |
38 |
|
39 |
Thanks in advance! |
