dropping dtr/getty

[Kenn Kantola]

I want to monitor dial in ports and drop dtr or reset the getty if a device has been inactive for so long. Is there a simple way to do this?

If you were just interested in telnet sessions, you can use nettune to set the inactive timer for closing idle connections.
However, it appears you want to close off direct (tty) connections.
The best way I have heard of doing this, is to install idled (pronounced "idle-dee").
The author does not specify if it is shareware or freeware, but you can read up on it and download it from the following location:

However:
Do you really want a port logged out due to inactivity, even if it has files or databases open?

[Kenn Kantola]

yes, these are direct connect modems. What they do on the current system is call a UNIX untility from the database programs after they close the files. So they will do the same on the HP, I just need to give them a command to execute, and I didn't want them using kills on pids. Thanks.

You asked for a simple way to do it; if issuing a kill is not an option, I think you have non-simple options.
You are looking for inactivity on a device rather than a process, right?
And it is currently allocated/open by a process which you do not want killed.

If you can determine that the device is idle by some other means, you can issue the command
stty 0

[Kenn Kantola]

Yes, on the device. I did download idled and am looking at that, but the stty command looks like it will work very well. Thanks for the help.

Glad I could help.

By the way, have you read the forum's notes on assigning points to answers?

It's not mandatory, but very helpful to the other forum users if you do.
