Hello,
My system is a Linux with two network devices, one of them
has a real direction, and the other has a private direction, both are
the same model REALTEK 10100. My version of linux is SUSE 5.3, it is a
firewall, it has a proxy server, it is a mail server (sendmail and pop3
).
When there are some people connect to it, for example
reading the mail or navigating in Internet, the interface with the
private direction, has many problems. From the linux I can ping only to
the private direction, I cannot ping to the other direction of the LAN,
and from all the directions of the LAN, I cannot ping the Linux's
private direction. So there isn't comunications between my LAN and the
exterior.
When it happen, some messages like this appear in the
/var/log/messages file:
Transmit timeout, status 0d 0000.
eth0: Tx descriptor 0 is 0008203c. (queue head)
eth0: Tx descriptor 1 is 0008203c.
eth0: Tx descriptor 2 is 100825ea.
eth0: Tx descriptor 3 is 0008022f.
I know that it is'nt a fail in the hardware ( network device
) because I have changed it yet and the same problem has happened
again.
Please, ¡ help me !,
I'm sorry because my english is horrible, Thank you very
much.
