| You prefer ssh over paramiko?  In that case, I don't understand how my
example would have worked for you - my example shows the ssh key is not
used to authenticate with Launchpad (hence plink can't connect), but
instead a couple of extra keys seem to be used by paramiko.  Can ssh.exe
connect to launchpad for you?  How about if ssh-agent doesn't have your
personal key loaded?

Yes. ssh.exe will notice that I have a key set up in ~/.ssh/config and
it will prompt me on the terminal to enter the password for it.

I don't know why plink is unable to connect directly to the terminal to
ask questions, and ssh *is* able to do so. It may be that it is a cygwin
program, but both are ultimately running under cmd.exe.

  But I'd expect to see the exact same behaviour if I installed ssh-agent
locally - finding ssh.exe on my path would be enough to prevent use of
paramiko, and lead to the exact same problems.

ssh.exe would skip paramiko, and if your only key is in pageant it
wouldn't work, correct. My only key is in ~/.ssh/id_rsa and has been
configured for ssh.exe to find it. And that works quite well.

The only real problem, atm, is getting the ssh-agent to be recognized
under all open shells. If I start it in one, the SSH_AGENT_SOCK isn't
propagated to all of them. A while back I had it all worked out.

I suppose forcing it to paramiko and manually loading my key would be an
option. I don't really know a way to get pageant to know that there is a
key out there that it *should* be using, and prompting the user for the
passphrase. I've only seen the manual "add this key" for pageant. Which
paramiko (and supposedly putty) can then try to use when connecting.
