Starting SSH in UNIX

I have been working on my UNIX box for just over 1 month.
The issue I am having, I cannot get my SSH to start on the system.
I have a few rsync programs that are depending on SSH.

Can anyone please let me know how to get SSH started back?

Any assistance will be much appreciated.

Thanks

Which UNIX? The answer differs a lot between different implementations and distributions.

In addition to what Corona688 already said: notice that SSH is a client-server system. It won't help to run the SSH-client on yours and the other system doesn't have the server started.

To really analyze what is going wrong we need a specification of ALL the involved systems and what they already run (or don't run).

I hope this helps.
