Our 2100, running DU 4.0D, has two NICs. One is 10Mb/s, another is
10/100 Mb/s. Only the 10Mb/s was connected to our LAN. About 2 weeks ago
we decided to use the 100MB/s NIC. So we deconfigured the 10Mb card and
configured the new 100MB card. Everything worked fine. This Monday we
changed the IP address which was a Class C address to a private Class A
address. Put the old address as an alias. Everything looked fine. We
didnot have problems to ping outside machines. About 10 Min after we
finished the reconfig, we canot telnet /rlogin to the machine. All users
became invalid. login in on the console hangs. Failed to reboot, we
booted to single user mood. Deconfigured the 100Mb NIC, the machine
rebooted.
Then reconfigured the 100MB card with the old IP address, no problem to
ping the IP address, but canot ping outside machines. Donot know what to
do, we deconfigure the 100MB card and go back to the old 10MB card.
Everything works. Looks like the problem is related to the 100Mb card.
We are planing to do two more tests:
1. switch the two cards
2. replace the 100Mb card with a new one.
Any suggestions, clues are highly appreciated!
