Hello:

Try with landamin in order to know the administrative and operational statuses of the interface.

Have you checked the link level with linkloop command?

Take a look too lanadmin -x to check the current speed and duplex mode.

Hi,

I'd try this test:
(assuming that lan0 is presenting problem)

#lanadmin -x 0 -> to know the speedy/duplex of tour lan.

#linkloop -i 0 0x0011855F5FCA -> to test the fisical conectivity with another hp-ux machine (0x0011855F5FCA is hw address of another hp-ux machine)

->Swap the cable used on MP with the cable used on lan0. If MP is still acessible, then the cable/switch port are proprably ok.

-> Verify the arp cache #arp -a

-> reconfigure the lan:
#ifconfig lan0 down
#ifconfig lan0 unplumb
#ifconfig lano 192.168.0.1 netmask 255.255.255.0 up

try to ping the Default Gateway from the server.
when you cant ping any server when you are logged in through MP, this gives to think about server connectivity.
try to do the traceroute on any other server or your machine.

Nejad,
Another test tha you can do is to use a cross cable to connect your server with a notebook for ping testes, taking out the network infraestructure.

Are u checked the connectivity through linkloop ,....suspecting prblm with the cable .

Hi Nejad,

You can check the lan statistics:
'lanadmin' - 'lan' - 'dis' will show you your settings.
After this 'Press to continue' appears, after you'll see the network stats - if there are 'FCS Errors' (not equal zero) then you've the problems at the network connection of your box.

Any firewall running on your PC?

This may prevent the "ping".

Also make sure all your NICs are on different subnets.

and the FCS = 0 what is the problem?
thanks
