connection keeps dropping

George_Dodds — Thu, 13 Oct 2005 06:31:37 GMT

Hi

I have an L2000 running 11.00.

when using putty to connect to the server i keep losing the connection, other users have reported the same and i have a script that rpc's files from another server that has been failing.

I've checked the logs but cant see anything useful in there.

The network admin has checked his side out and we cannot see any issues. we arent getting any packet loss on pings and there arent any interface problems.

This is all on one lan so there is no firewall involved, all other servers are ok.

Any ideas??

Enable syslog. inetd -l

What are the messages do you get?

Interface settings are ok and there isnt any great amount of network traffic as this is a cold spare server for our prod setup.

I have enabled connection logging, but it doesnt show the disconnects and the reason for them.

The length of time till i get disconected varies.

Sometimes i lose connection withing 2 minutes, other times it's 10+ minutes.

I've noticed that when i telnet to the box it sometimes takes 2 attempts to establish connection.

Could be a duplicate IP address on the LAN?

Also have a look at the statistics for your lan card using lanadmin - are you seeing any errors?

Have you restarted Inted ?

lanadmin shows no errors and the server was rebooted this morning to sort out a db issue.

There was a linux box that used to mimic the HP server for a previous issue, it looks like the interface details were not deleted.

When the linux box was rebooted a yesterday the virtual interface came up so it was in conflict with the HP server.

The Linux admin has deleted the interface and all is well.

THanks folks :)
