I use ssh a lot. I always have windows open to many of different
systems. I make extensive use of ssh keys, ssh-agent, etc. This makes
for very convenient yet secure communications. I sometimes code in emacs
and use tramp mode to edit remote files. I tunnel svn (and soon hg) over
ssh also. To reduce the latency of transactions over ssh I use ssh's
ability to tunnel multiple sessions over one ssh tunnel. I accomplish
this by putting the following in /.ssh/config:
Host *
ControlMaster auto
ControlPath ~/.ssh/[EMAIL PROTECTED]:%p
But this has been bugging me for a while and the problem seems to be
getting worse:
[EMAIL PROTECTED] ~]$ svn ls
Control socket
connect(/home/treed/.ssh/[EMAIL PROTECTED]:22): Connection
refused
ControlSocket /home/treed/.ssh/[EMAIL PROTECTED]:22 already
exists
svn: Connection closed unexpectedly
svn tried to connect to svn.copilotco.com to take a look in the
repository and it tried to do it over the control socket which exists
where the local ssh client which first connected to svn.copilotco.com is
supposed to be listening and willing to tunnel additional sessions. But
it isn't listening for some reason. Probably because I don't have any
other sessions existing. This is a stale socket. For some reason the ssh
client is not cleaning up after itself. I can do:
rm /home/treed/.ssh/[EMAIL PROTECTED]:22
and then it will work. There is a bug filed on this in debian:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=352830
but I don't see if it was ever fixed. The openssh version I am running is:
OpenSSH_4.7p1, OpenSSL 0.9.8b 04 May 2006
and I am up to date on FC8. Anyone else ever seen this or know if it was
fixed in more recent openssh?
