gregor-e,

Just to point out what you probably already know, I compared the 'good' and 'bad' outputs you provided, and 'bad' shows that you received 'channel 1: rcvd eof' from the remote server. Someone more familiar with Net::SFTP may give a hint on why the remove server is acting differently on 'cron' or 'at now'.

I use 'rsync' with public/private keys and 'ssh' to encrypt the session. It's not a pure-Perl solution, but has worked for years. Maybe answer this post on Monday, when it may be picked up in RAT, and more monks are available. Things that you could look into:

• Configuration parameter about timing ( cron maybe faster then the shell??? )
• You may want to look at http://www.perlmonks.org/?node_id=977128"> which talks about '...Net::SSH2 was designed to replace the old sftp and ssh module..." (again through super seacrch).

Good Luck!
