If you're copying the whole directory over, I would recommend using rsync 
instead of scp as it'll reduce bandwidth and server load over the long term and 
the clients generate more data.

You can use rsync's '-e ssh' option to have rsync use ssh instead of rsh and use 
the passwordless login you've set up.

I would try to pass -v to the scp command and run scp from the command line and 
see where it hangs.

It's not clear why it's hanging, just need to do more debugging work.
