Hpn-ssh? #4

Hey there, a colleague saw your presentation at PEARC and sent me a link. Have you looked at hpn-ssh in terms of mscp? If not please take a look GitHub.com/rapier1/openssh-portable. I'd be interested in talking to you if you like.

@rapier1

Yes, I have tested mscp with HPN-SSH, and it improves throughput per connection. The result is not included in our PEARC paper because of space limitations, but our paper references your paper of course.

If you don't mind, I would send you our paper and slides presented in PEARC (is hpn-ssh at psc.edu ok?). I'm also interested in your comments.

I thought I had replied to this but I seem to have failed in that. I would love to get a copy of your work. Please send them to rapier at psc.edu as that's the best option.

Have you considered porting this directly to openssh or hpnssh? Depending on how thing go I wouldn't mind seeing mscp as possible offering in hpnssh.

I sent you materials!

Currently No. mscp implementation depends on libssh. So, porting mscp to openssh or hpnssh requires effort. In addition, I think mscp provided as an independent package is easy to install than building/installing out-of-tree openssh for users (until merged, or ever).

This would be very interesting, supporting hpn-ssh could potentially increase the transfer speed by disabling encryption after authentication to transport non-sensitive bulk data.
