Server Dropping???? 1

[juggers]

Hi all,
We had a netwrok problem where users suddenly can not reach the sun server E250 (solaris 2.6). We are searching for a loop in the netwrok. I am having doubts that the Server himself is dropping from the network. Is there any way that i can chek that?? the check should be done on the server itself becuae the network is not reliable.

Thanks in advance.

You can try running dmesg to see if you network port is going offline.

In the /var/adm/messages (which dmesg interrogates) look for the string (link up) you should see at least one for when the machine booted.

If you see the string link down, then this indicates the server itself lost it's network connectivity. for the period until the next link up message.

Lastly use ifconfig(1M) to check your NICs.

cheers,

Dave.

to clarify no brackets.

dmesg | grep -i link

Just run the above.

SOlaris 2.6 is very old, are you able to upgrade?
