I wrote a patch to make the number of times and and the delay between retries
that ssh attempts to talk to ssh-agent configurable. This patch is
indispensible when running multiple ssh sessions in parallel from a script
(e.g. to run commands on a large number of hosts); without the patch, many ssh
sessions simply fail because they cannot contact the agent, rendering the
mechanism unusable.
If there is sufficient interest to incorporate this patch into a future
OpenSSH version I'll post it here.

We start between 50-100 ssh sessions within a short time period, and they all race to connect to the agent socket. Some of these ssh processes fail so they have to back off and retry. We could also have put the retry mechanism in the tool but in our case it seemed to make more sense to put this functionality in ssh. -- Jos Backus _/ _/_/_/ Santa Clara, CA _/ _/ _/ _/ _/_/_/ _/ _/ _/ _/ josb at cncdsl.com _/_/ _/_/_/ use Std::Disclaimer;
