RE: A problem with OpenSSH 3.8.p1-1 - ssh-agent

["Karl M" <karlm30 at hotmail dot com>]

Hi Andrew...

Please keep this on the list so that it gets archived for others to search.

I'm not seeing this problem. I use win-2k and xp machines.

You mentioned that you use a script to launch ssh-agent. I use keychain 
(also a script to launch ssh-agent) for that. I launch it from a service, so 
the agent stays aroung from reboot to reboot. If I launch it from within my 
~.profile it only stays around for one login session. You also mention that 
you launch it from profile.d...Is that part of the sysvinit stuff?

I'm attaching the script I use to launch keychain and the script that 
installs the service with cygrunsrv in case you want to try that. The rm -rf 
in the launch script keeps the ssh-???? folders from accumulating.

HTH,

...Karl
