Telnet timeout terminal session

[Goran Kubelka]

What is the default timeout for terminal connection via telnet and how to change or disable it on HP-UX 11i host

[Robert-Jan Goossens]

Hi,

You can check yout timeout value

# print $TMOUT

where 0 is no timeout
and 60 is 60 seconds.

change
# set TMOUT=XXXX
and add this to your .profile.

Kind Regards,

Robert-Jan Goossens

Which timeout do you mean? There are several TCP timers and there's a shell timeout for disconnecting idle sessions (see man sh-posix and search for TMOUT), TMOUT is disabled by default.

The default timeout is infact notimeout.

i.e.
TMOUT=0
autologout=0

When these values are zero then it is like no timeout for the sessions.

Incase you need to set the timeout value you need to change them.

Thanks

Dear ALL,
Actually I `m using Terminal emulator to establish telnet session to HP-UX host.The shell is ksh. The value TMOUT=0, but I `m still disconected from the host aftr 5-10 min. inactivity. Any idea?

[Robert-Jan Goossens]

Oke,

If you're using reflection
check
Connection
Settings
Field Time Out Settings
120 (my case)

Regards,

Robert-Jan.

At the moment I`m using Power Term 525 , but I have same expirience with other terminal emulators like Humminbird etc.

[John Palmer]

Are you are connecting to the server via a firewall? I've seen this problem where the firewall had an inactivity timer set.

You have to see the " echo $TMOUT ".
To set this value:
/etc/profile

TMOUT=300

For example 300 seconds.

I hope this help you.

[melvyn burnard · Accepted solution]

sounds like you have some form of firewall or other mgmnt system that is detcting inactivity and logging you off.

[Goran Kubelka]

It was definitly Firewall setting

[Steven E. Protter]

I access without a firewall and can leave Hummingbird logged on for days.

That's probably a problem. Though Win2K locks the screen.

I'm setting TMOUT on my new servers and my development server.

Thanks!!!

I would also say it's Firewall settings. I have the same problem, but it happened not only to telnet session, but all remote access(like oracle DBA console etc...) which makes me believe it's not some setting of telnet.

Goran, can you please give me the details of the firewall setting it turned out to be, that corrected your problem? I am having the exact same problem, and would really appreciate some help. thanks!
