today, when I came to office. I saw that our production server is not seen
by any tcp/ip connection. Moreover, i could not connect the outside world
...But i could ping the machine own IP and it has found himself..
As you can see our production server has 2 NICs
1- ethernet (10 MBit, copper wire): only LAT conections is done over it (NO
ip address is defined on it)
2- ATM (fiber medium): only TCP/IP connections are done over it.
What is written on the console window is this :

- I still could not resolve the network problem.
Can you recommend anything to resolve this problem ....
- or How can I understand the problem is from network or from our unix host
- And moreover,
what I thought as another solution is to ;
define an IP address on ethernet card ... I hope this will work ...
But I dont know how to define an IP address on such an ethernet card.. and I
dont want to bother LAT connections..
can you help me .. ?
TIA...
