What are the effective ways to exchange files on different servers with Shell Script?

Question

I want to update some file in a server, with an automated script and the target files on a different server. Haven't started yet, but I think there will be authorization and connection issues during the process. Any suggestion on how I could approach?

Thank you

Answer 1

Set up ssh keys so that you do not need a password. You can then use scp or rsync.

More sophisticated systems:

• chef
• capistrano

Answer 2

• Easiest solution is cross-mounting the filesystem (e.g. NFS) across servers.
• If your servers support rcp/rsh, you can use .rhosts file to allow automated connection.
• If only ssh/sftp/scp is available, Google for automated ssh/sftp - it is doable but trickier to set up.
