I am trying to write a script that syncs files from source to destination. I have one centralized server that can ssh to any servers without pw. Now when I run the script, it can ssh to source server perfectly fine, but you need to enter password for destination server. Was wondering how I can clean this up before I start using case statements
Your server is not sshing to $S and $DS, your server is only sshing to $S and then telling $S to ssh to $DS. $S needs to be able to ssh into $DS without a password if you want it to work as written.
I do not believe rsync will allow you to sync between two remote systems without a direct ssh connection between them. You'll either need to set up ssh keys between your source and destination servers and use your code as-written, or do the sync in two steps using your centralized server as a neutral 3rd party:
rsync -av root@$S:/dir $S/dir
rsync -av $S/dir root@$DS:/dir

I was just thinking about setting up ssh keys between the two source and destination servers. And I think the man page for rsync specified that you cannot sync between two remotes. Besides that, I don't know any other way to sync between two remote servers without pw prompt. This is so that if there are any big moves, I don't want to be up all night watching the progress of it.
