Capistrano was working extremely well until a few weeks back. We have
been unable to determine what change has caused our sudden connection
failures. When the SSH command is run manually on the command line, it
succeeeds without complaint. When the exact same command is run via a
task, it fails:
[EMAIL PROTECTED]:/var/www/brews> cap -S deploy_type=dr deploy:cron:show
* executing `deploy:cron:show'
* executing "crontab -l"
servers: ["host2.domain.net", "host3.domain.net"]
connection failed for: host2.domain.net (Net::SSH::Disconnect:
connection closed by remote host), host2.domain.net
(Net::SSH::Disconnect: connection closed by remote host)
[EMAIL PROTECTED]:/var/www/brews> ssh host2 "crontab -l"

Even more interesting, the Capistrano task will succeed if it is
executed by some account OTHER than "tools," following a standard
password prompt.
Capistrano v2.4.3
Net::SSH v2.0.3
This one is making me crazy!
