You can simply verify your connection by doing the following:

ssh mahmoud@

If this doesn’t work, then you need to check that you can connect  
to the host using SSH. Then you’ll need to verify that you’re using  
the correct credentials.

If it does work, then you’ll need to check that you’re the correct  
credentials within your Capistrano configs.

Good luck,

The above command is to be performed at the command line.
