[Techtalk] ssh problems

[Lorne Gutz]

The problem here is a slow connection I would say.  I use a 
64k connection between two sites at work.   Sometimes this
connections exhibits the symptoms you describe.  

There is a lot of necessary overhead when you use ssh.  Its 
the price one has to pay for a secure connection.  I find it slow
even over an ASDL connection at times.   Still I prefer it over
any other type of secure connection.

We also use X forwarding to bring up GUIs and they work fine
but like you say they get slow at times.   You might find that
changing the type of crypto used could help.  Check out the
-c option and play with it.
