linux - how to configure the bash session timeout
Red Hat Linux version 8.3 - In a bash terminal session, it's annoying after every few minutes when I have to retype my password. How to configure the timeout variable or whatever it's called?
(I'm in a gnome environment, in case that's significant.)
Thanks

Local session at the computer, or remote? If remote, via telnet or SSH?

Actually, I'm running this instance of linux within a VMWare environment. Might it be possible that the short timeout window has something to do with VMWare ESXi? I don't think so.

It's a console session within the RHEL vm in Vmware
Graphical or Terminal?
See https://access.redhat.com/discussions/2973871 for an example, check display related preferences/settings.

So since I'm in a terminal session, I assume the screensaver solution above is not my answer?
How do you enter the password? Does it follow the "sudo" command? if so add the following to your /etc/sudoers file:
Change the timeout of "20" according to your needs. A reboot may be required for the new setting to get registered.
Defaults env_reset,timestamp_timeout=20

It would surprise me if a variable for (I assume) all bash sessions would be set in the sudoers file ... but I'm trying it.

I think it may be a vmware thing.
I figured out that if I'm just in the console session, it times out. But if I do ctrl+alt+F3 for example to go to tty3 - it doesn't time-out. I may have solved this. So I'm guessing this isn't a bash thing at all.

Try to see if env variable TMOUT is set for you:
echo $TMOUT
This variable defines the ideal timeout for session.
You can change this by running
N is time in seconds.
You may change it to 0 to disable timeout.

You can change this by running
export TMOUT=N

Try
export TIMEOUT=0

setterm --blank 0 will stop your VT from blanking out, if that is your problem
For BASH it is called TMOUT and you can configure it in ~/.bashrc or in /etc/profile ...
TMOUT If set to a value greater than zero, TMOUT is treated as the default timeout for the read builtin. The select command terminates if input does not arrive after TMOUT seconds when input
is coming from a terminal. In an interactive shell, the value is interpreted as the number of seconds to wait for a line of input after issuing the primary prompt. Bash terminates after waiting for that number of seconds if a complete line of input does not arrive.
How are you connected to that RH server? Are you perhaps using PuTTY? In PuTTY settings you can enable keep alive settings so you don't get disconnected. Those settings are not configured as default.
The asker is connected to the Console 9f a VMWARE virtualized RH VM.

I'll close this question tomorrow. Thanks so much to everyone for their help.

Folks ... I've searched .bashrc as well as /etc/profile - I can't find anything setting TMOUT or TIMEOUT
Which doesn't mean of course that those comments are invalid - but it's not in my environment.
Meanwhile, I did solve the problem by just going into a different tty. It appears that my VMware console will timeout; but the tty sessions do not.

ls -l //etc bashrc profile login etc are system wide settings.
in the local user .bashrc .login .profile see whether it sources other files.
try echo %TMOUT
please clarify on the console, using the key to toggle to another "session"?
console login as regular user or as root?
If not mistaken, the option might be set in the console/listening event/handler.

echo $TMOUT probably works better than echo %TMOUT (at least on any UNIX/Linux)
If you ony checked /etc/profile you may have missed it see also advice like this:

Yes, incorrect deference of a variable
