HP9000 telnet problem

[Scott McMullen]

I'm new to this!

I have an hp9000 that after i do a reboot i can no longer telnet to i just get a blank window. I have found out that if i hit control B enter the system seems to come alive.

Any suggestions please help?

If you are running this from the system console, be careful about using ^B or ^V as they are special keys to the system eeprom on certain platforms.

Hi,

Check whether you have 'telnetd' running on the system ? Check for inetd daemons too.

Also which server ? which OS ?

Hi,
Try to check telnetd daemon is running?
check /etc/inetd.conf

for following entry

telnet stream tcp nowait root /usr/lbin/telnetd telnetd
(This is a single line)

also check /etc/services

After making changes to /etc/inetd.conf run following command

# inetd -c

this will cause system to reread the modified inetd.conf file.

Thanks,

Sorry about that the os is hp-ux 11.0 and it is control D after telneting and getting a blank window. You only have to do this was and all other telnet session are fine

Scott

What are you telnetting from?

If it is a remote telnet program then have a look at the session settings.

Most telnet sessions will stop upon a server reboot and have to be told to retry.

It is a clean telnet session after the reboot.

Hi,

Okay, firstly, check the /etc/profile and ~/.profile files and see if they have anything in them that would cause a hang like what you describe. Things to look for are unfinished quotes, ie "

Also, try telneting from various machines on the network, especially ones which are in the same subnet as the one you are connecting to.

A control-D signifies an EOF to unix, so it may be something to do with a read or something. Perhaps double check /etc/issue?

Hmm, how long have you left the telnet window trying to connect? Try telneting to the machine but don't type anything, see if there is some sort of timeout after a few minutes. This might give more information.

Also, sometimes X and xterms can have trouble processing .profiles and other things. I can remember once when someone patched his HP-UX workstations and afterwards his xterms on his own machine were blank. He had to do a control-D or something like it to get a prompt. Unfortunately I can't remember what the problem was. Might have been something to do with /etc/gettydefs. Perhaps a later patch fixed the problem.

Hope you find a solution.

Please clrify me onething!

Are you facing this problem of not getting the server login screen by doing a telnet from single node/PC or this is the problem faced by all the nodes/PCs.

If it is specific to a single PC or node check the network connectivity of that PC/node .
May be you can ping the server from that PC /node.
