[Capistrano] Re: SSH Auth Agent failures?

[Jamis Buck]

The Pageant interaction relies on the Ruby/DL library (bundled with Ruby) to call into native C routines and communicate with pageant via the windows interprocess API. I didn't write it (it was contributed), and I don't have any way to test it--can anyone else confirm that these errors are happening to them?

I wonder what would happen, Andrew, if you upgraded your Ruby to the latest 1.8.6.

We have several servers in production which we're managing with
Capistrano.  We do not use public key authentication to connect to
them.  I do use public key authentication to connect to other
machines, so I have Pageant running to hold my key for them.  When I
try to connect to our production servers, I get random errors when
Net::SSH tries to talk to Pageant.  If I try over and over again,
eventually it will work.  If I kill Pageant, the errors go away as
well.  Here is the transcript of a particularly bad session.  I'm
running our "grep_production_log" task to search the log files.
Ultimately, it doesn't find anything.
