#but no files
# same with https

I presume the culprit is a firewall, but the keepers of the firewall
are not very responsive to change requests.

I do not have an account on the the server and so can't ssh.

Is there an alternative?

The only system I can access outside the firewall is my home machine
(from which the first line works fine); maybe I could tunnel 3690
through it?  Even if it works the connection will be very slow.

Thanks.
