In all likelihood you do NOT want sshd to kill your shell because you loose connection for a while. Let me repeat: you do NOT want that. Really? Should I call Red Hat, SUSE, Debian and Ubuntu and all the others and tell them they've been doing it wrong all these years? That's *exactly* how every Linux I've ever used works. You want the ability to reconnect to that session once the physical connection is reestablished. screen gives you that ability. I know about screen. I use it regularly. But screen is off-topic. Unless there is some way screen can re-connect to a dangling bash session; I thought screen could only re-connect to screen. If it has that ability I'd like to be educated to it. Some days ago I brought up a GUI session to a remote W2k3 box, ran task manager and almost fell out of my chair to see bash.exe listed nearly a dozen times. I thought the thing had been rooted or something. Surely there is some actual solution to this. It works splendidly on Linux. And when I am doing something critical that doesn't need to be interrupted, then our mutual friend screen is always there waiting. Can anyone offer some help? Please?

Bash process hangs around forever after ssh disconnect
I'm seeing this on several systems... I'm logging in to a W2k server via cygwin sshd and using Putty as my terminal emulator. If my ssh connection gets dropped for any reason the bash.exe process on the host just stays there forever. Also, anything I was running in bash (e.g. vim) will stay there forever. I'm having to use taskman to clean this up periodically. Anything that can be done about this?

Re: More pipe problems (was Re: [Fwd: 1.5.11-1: sftp performance problem])
This solution is problematic as the Unisons avail with Cygwin are beta versions 2.9.2 or 2.10.2 whereas the latest stable unison is 2.9.1. Normally this wouldn't be a problem except these versions will not run with a 2.9.1 version at the other end (Unison seems somewhat unique in that regard - requiring the exact same version at both ends). And it's simply not always possible to control what version is available at the other end.

Bingo. As I was reading your message, I thought he should check that he
has system mounts. You've just confirmed that you don't. Re-mount all
of your mounts as system, and your services will work.
David, this is definitely an FAQ, but there is nothing in the FAQ about
services (other than the how do I install snapshots entry). Should we
add something along the lines:
Why don't my services work?
Most Windows services run as the SYSTEM user. If you installed Cygwin
for Just Me, the SYSTEM user won't see the mount table. You need to
re-mount all of your mounts as system for services to work.
We could even include the recipe for remounting as system (e.g., from
http://cygwin.com/ml/cygwin/2003-05/msg00487.html), or tell them to run
setup.exe again and select All Users on the Install For screen (and
use the Keep view, so that nothing gets upgraded accidentally).
Thank you (all) ever so very much.
I had no idea what it took to re-mount all your mounts as system but I
did the {eval `mount -m | sed -e 's/ -u / -s /g' -e 's/$/;/'`} from
the msg referenced above and it now works like a charm.
(There are some occasional other users of this machine and I don't
really want them to have access to something as powerful as cygwin so
re-installing for all users was definitely not the preferred solution.)
Hmmm. I wonder if this will help another installation where Task
Scheduler jobs don't seem to have access to windows network drives.
Worth a try.

It does this regardless of all-powerful exclusions that would cause it to skip over pagefile.sys. Even touching that file enough to realize to exclude it evidently causes it problems.
