What exactly is outbound ssh? How to use it and what are the benefits of having it?

Could you add some context to the question? Where are you seeing this? –  David Mackintosh Nov 24 '10 at 17:50
    
I am just trying to understand the differences between regular (inbound) ssh and outbound ssh. –  hari Nov 24 '10 at 17:56

The difference is direction. One isn't really more "regular" than the other. In fact, any given cross-network ssh connection is both -- it's just a matter of where you're standing. –  mattdm Nov 24 '10 at 18:50
    
Thanks, mattdm! –  hari Nov 24 '10 at 22:34

That would be ssh traffic originating from your site and connecting to other sites.

You would use it to securely connect to those sites, generally for interactive shell login but possibly also for file transfer, batch-style commands, or port forwarding/tunneling.

This is opposed to inbound ssh, where someone (you at home, or your customers, or whatever) would connect to a service you run.

You might block it if you want to strongly restrict what people can do from your network.
