You could probably rig something up using a fixed agent socket path. E.g. IdentityAgent ~/.ssh/.agent-sock Match !canonical exec "check-and-start-agent.sh" # Will start agent at ~/.ssh/.agent-sock if not already running. The agent socket is AFAIK only opened after configuration processing completes, so this should work. It might also be possible to skip the Match block using some socket activation trick. -d _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
