To figure it out I'd have to either: No, no, it's fine, and if the key isn't loaded or {CYGPORT_}SSH_KEY isn't set it's all the users fault, IMHO. Your description somehow made me think lftp would *always* ask for the passphrase, even if ssh-agent with the correct key loaded is already running. On second thought, that wasn't very rational.

I think it's an okay compromise. Absolutely. Thanks, Corinna -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Maintainer cygwin AT cygwin DOT com Red Hat
