Re: [Ssh-sftp-perl-users] sftp to a Microsoft server regularly hangs

Solution!

I found a google hit about not having the GMP library
properly installed, causing SFTP to go into a much slower mode.

I had to track down a permissions problem in my perl install
directory tree, but eventually I found it.  

Now the negotiations are going much faster, more like
what I see with the sftp commandline tool.  Maybe
even faster than that.

I've done a little more research on this but still
could use help.

The remote server is an F-Secure 3.2.0
and I've seen some google hits about it being in some
ways incompatible with OpenSSH keys.  But otherwise
I haven't found any particular indictment of the
F-Secure server with perl SSH or SFTP.

When I use my command line SFTP took it works fine.
When I try my perl SFTP script it rarely gets through
and when it does it takes a very long time in negotiation.

I'm trying to use perl sftp to connect with a remote site
and upload/download some files.  The remote server says
it is SSH Windows NT Server using protocol version 2.0.

If I do this in the middle of the night, presumably things
are quieter,  it usually goes through without a problem.
If I run my script during the day it gets through a few
steps (I have debugging turned on) but eventually just
seems to peter out during the negotiations, frequently
while doing something about "NEWKEYS".

Is there anything I can do on my end to make the protocol
negotiation and all of this stuff go more quickly?  in
the hopes of getting the connection established and 
my traffic completed in a reliable fashion.
