nonstandard ports, continues anyone have a shell server I can use for a test?

[Linux for blind general discussion]

Hi Folks,
This adventure is reaching a new chapter.
As it stands every single location I try visiting produces the same dh key 
error, save for one.
here at shellworld we use a different port from 22 ssh and 21 sftp.
There is a slight chance that my dsl provider has made security changes 
that prevent me from  using my non windows setup to reach servers  on the 
standard ports.
In order to find out I need,
a, to borrow someone's existing server for a few tests. or
b, the name of a company  other than shellworld who provides their shell 
services on a nonstandard port.  Some do for security reasons.
Any ideas?
Thanks,
Karen
