KB-5452: How to enable debug for PuTTy / SSH clients?

Authentication Service ,

Applies to: All versions of Centrify DirectControl.

How does one enable Putty debug in Centrify Putty/stock Putty?

A) If you are using Centrify Putty or Stock Putty
Configuring PuTTY Debug Logs:
  •    From the PuTTY Configuration, in the left pane, click on  "Logging" under "Session".
  •    On the right, ensure "Log all session output" or "Log SSH packet data" is selected.
  •    Note the path to the log file which needs to be sent along with sshd logs.
B) If you are using Unix/Linux SSH client (as opposed to Putty):
Configuring ssh Debug Logs (at the Unix shell)
  •    Simply add "-vvv" (three "v" 's) to your normal ssh command; for example:
   #ssh -vvv <usual_options>
   where <usual_options> means server name or username@servername.

The debug information is output to the screen; you will need to copy/paste this information.
