Remotely connecting to HP-UX poses a lot of problems
2)ip of the hp-ux machine is rrr.rr.199.rrr
3)i need to access this hp-ux machine remotely from a windows machine on the same subnet,as in from a windows machine that has an IP address set to rrr.rr.199.***
4)I use putty or xmanager to connect to the Hp-UX machine remotely.
5)The issue i am facing is , the hp-ux machine comes into the network and goes out of network randomly as in i can connect to the hp-ux machine remotely once from windows, but the network connection gets disconnected after 2-3 minutes.I have a lot of Non windows machines(RHEL,Solaris) in the network, they do not give me this problem.
If i try to re-connect it says connection refused.
any help would be greatly appreciated
Thank you

also check the netconf files and also routing tables.

Re: Remotely connecting to HP-UX poses a lot of problems
I think the problem is with your windows system's network. Try to do a continuous ping from windows to the HPUX system. Hope there will be intermittent request timed out.

Re: Remotely connecting to HP-UX poses a lot of problems
Login to the HP-UX machine vi the console or iLO and do a continuous ping out to a known stable network device. If you notice an interruption in the ping, check your hardware and cabling for link lights etc. At the same time check the HP-UX LAN status using ifconfig and lanadmin.
On another thought is it possible another machine is using the same IP as the HP-UX machine?

> refused.
"Connection refused" normally means that you
can talk to the remote system, but that the
program which should be handing the
connection request has gone missing, somehow.
If you're really seeing "connection refused",
I'd be looking more at the software than at
the network hardware. (Although I can
imagine a case where a network problem might
confuse a server program thoroughly enough to
keep it from answering the next connection
request, I've never seen that happen.)

Connect how, exactly? SSH? Telnet? X?
Any evidence collecting in the log files?

Re: Remotely connecting to HP-UX poses a lot of problems
Windows network may not be a problem since we have as many as 200 machines which are stable.
Problem is appearing only when we connect to hp-ux, solaris and Linux do not provide a problem.
>>check the lan speed set on the network card. change it to autonegotiate
how do i accomplish the above.sorry to ask this, i am a QA guy and am not completely aware of sys admin internals of hp-ux.

It is SSH.
There is no firewall on windows machine

Re: Remotely connecting to HP-UX poses a lot of problems
The physical connection is not up to standard or bad contact. This may cause the LAN to negotiate with the LAN switch for the right LAN speed again. This can be solved by setting a dedicate LAN speed on either the server or the switch.
The command should be similar to the following:
lanadmin -X 100FD 1
where 1 is the NMID you get from lanscan for that particular LAN card. Do a man on the lanadmin.
