Re: a dh keys question?

1.
I am not using Linux, but an ssh client compiled from a combination of 
tools, Linux and otherwise, including putty.
I have been very firm in not stating that I use Linux at all.
In fact the first sentence of my question stated that while the issue is 
complex, the question, where dh keys are generated, was simple.
2. I can state firmly that the port number  has absolutely a great  deal 
to do with my issue.
best evidence?  your getting this e-mail at all.
I am writing using a shell service that uses Ubuntu 16.04 as its 
platform...same as dreamhost.
we do not use port 22 here, and I can use my ssh client to reach my 
workspace..doing such as we speak..
Likewise  an associate who hosts their  own servers created a temp account 
for   me, using port 4460...worked perfectly.
I respect other factors might  be involved, but my goal is the swiftest 
solution that lets us move our services from dreamhost somewhere else to 
which I can ssh from my desktop.
If choosing a location with a port other than 22 solves the issue, it is 
good enough for me.
