Hi Jason,
Thank you for your help but it is a persistant failure. I have tried with
different SSH products, changing the time-frame, extent etc.
I have now contacted our IT person at our department to come have a look.
I thought that because I am trying to access it from our campus, there
might be some kind of block or setting or something on the University's
side that perevents me from connecting to AVISO's server. Do you think
that might be a possible explanation?
Again, thank you,
Mia
