I have a problem with PowerEdge 1850 Dell. Second NIC can be seen in CentOS3.4: I can ping and ssh when I inside of my server, but from outside can not get any connection. Connection LED is green, but activity LED is not flashing and not lighting. Cables and network are OK, since all works for first NIC.
ifconfig command shows all ok for both NICs, during start up there no error messages, but no connection. IPs are in the range and differs by last number only:
Linux does not complain and from OS point of view it sees all...
Have you folk any idea?
