OK - so something else, somewhere, must have been starting ssh-agent without

am asked for the password, though, every time I transfer files. There
doesn't seem to be a conf file where you can set the key to remain active for
a specific time, as there is with gpg.
These are also good resources, if you'd like to learn more about the SSH
agent:

I dislike keychain, personally, but if you find that it's secure
*enough* for your environment, then it may be useful.
I prefer to use ssh keys with no passphrase, bound to a single command
on the remote host using this syntax:
command="do something specific" ssh-rsa ....
