All machines are connected together via a LAN (crossing over different subnets). Okay, that eliminated anything having to with a modem, ISP time out, or other external factors.
Does the target machine have a timeout for inactivity? As far as I know, none of the Unix machines (Solaris) have any type of timeout or time limitation for telnet connections. Do they time out if you log on directly, and stop using them for a long time? It's not necessarily related to telnet, but to login. Keywords (if you're asking someone else) are "idle time" or "inactivity".
I've tried timing these disconnects, but I haven't gotten any hard timings. Usually the disconnects happen after I've been doing some work on another machine and then go back to using the Suse box. Ok, that's a clue. It's probably not a timeout. Timeouts should be pretty consistent.
I'm using KDE2 with Suse 7.3 running Konsole for telnet sessions. Then it's probably not an application problem.
Over the last couple of days, I've begun to think that maybe there is not a problem with Suse 7.3 per se, but a problem with the way I've got my hardware setup. For work, I use two machines (a Win2K box and a Suse 7.3 box) with a Sun monitor and Belkin Omni Cube KVM switch. I use the <Scroll Lock> key to toggle the monitor over from Win2K to Suse and I really notice the problem when I use the Win2k box for a long period of time. If I use Win2K for let's say 30 minutes, then toggle back to the Suse box, the monitor LED just blinks until I hit something like the <spacebar>. When I hit the <spacebar>, the monitor clicks and hums, then displays my KDE desktop. Do you think that this has any bearing on the problem? Is it possible the Linux machine is powering down? Do you have energy saving features turned on? So it goes into a low power state and turns off the network card. I'm kind of guessing here. A more formal experimentwould be: 1) Telnet from Linux. 2) Use Windows for 45 minutes. 3) Jump back to Linux. 4) Check the telnet session - it should be disconnected.
If you can do that twice in a row, with the same result, then it's probably the culprit. -- Robert Wohlfarth rjwohlfar@galaxyinternet.net "Is not life more important than food, and the body more important than clothes?" -- Matthew 6:25b
