The following message is a courtesy copy of an article
that has been posted to comp.security.ssh as well.
I have sshd (from openssh 1.2.3) running on my home machine (Debian
GNU/Linux 2.2), and when I'm at work I like to start an Emacs like
this:
ssh -f -l offby1 my.home.machine.net emacs
(At work I use ssh 1.2.27 from http://www.cs.hut.fi/ssh on RedHat
6.2.)
This works fine, except: often, after iconifying Emacs and then not
using it for a while (an hour or two), I will restore it, and it will
then vanish. At the shell prompt from which I started the ssh client,
I will see a message that says `read from my.home.machine.net:
connection reset by peer'. There will be no log message on the server
machine to indicate what went wrong.
I've tried restarting the daemon with the line `KeepAlive no' in
/etc/ssh/sshd_config, but that made no difference.
I haven't yet tried running the daemon with debugging turned on.
Until I do that, though, can anyone suggest why this might be
happening?
Thanks

Is the home machine on a dialup connection? Is the connection going down and then back up? -- jim knoble | jmknoble at jmknoble.cx | http://www.jmknoble.cx/ Circa 2000-Jun-21 17:06:03 -0700 schrieb Eric Hanchrow: : The following message is a courtesy copy of an article : that has been posted to comp.security.ssh as well. : : I have sshd (from openssh 1.2.3) running on my home machine (Debian : GNU/Linux 2.2), and when I'm at work I like to start an Emacs like : this: : : ssh -f -l offby1 my.home.machine.net emacs : : (At work I use ssh 1.2.27 from http://www.cs.hut.fi/ssh on RedHat : 6.2.) : : This works fine, except: often, after iconifying Emacs and then not : using it for a while (an hour or two), I will restore it, and it will : then vanish.

There are often implicit timeouts which can clobber long running but quiescent TCP connections. -d -- | "Bombay is 250ms from New York in the new world order" - Alan Cox | Damien Miller - http://www.mindrot.org/ | Email: djm at mindrot.org (home) -or- djm at ibs.com.au (work)
