Description Nam Duong 2012-02-28 17:05:51 UTC

Description of problem:
One of our users raised the problem that none of the following clients can connect through ssh:
  - sftp
  - WinSCP
  - Putty

I also noticed the same issue with macfusion.

When diving into WinSCP and Putty (more common on Windows than cmdline openssh), I noticed that it didn't support the same ciphers as openSSH.  There is a tool that can be used to generate ssh keys called puttygen.  Tried 2 different approaches that also didn't work:
  - convert the keys generated by openssh
  - create new keys and post them to the domain (via control panel)

Please note that there are 3 users so far, 1 on Mac and 2 on windows whom are having problems.  The workaround is to use command line ssh and scp...

The issue with putty may be related to a key format compatibility issue.

Nod, this isn't a bug with OpenSSH/OpenShift, it's a bug with putty and some of the other windows based ssh clients.  They use a different key format.

Nam, can you create an FAQ that links to Rob's URL (or just re-write the FAQ with similar information.
