Debugging the HP-UX Secure Shell Client
One of the best tools for troubleshooting the HP-UX Secure Shell client is the verbose option,-v.
With the -v command-line option, the HP-UX Secure Shell client displays helpful messages such
as the version number of HP-UX Secure Shell, type of authentication methods it is attempting,
and the authentication method that has succeeded.
In addition to the HP-UX Secure Shell client, the -v debugging command-line option is available
for the following HP-UX Secure Shell commands:
• ssh-keyscan
• sftp
• scp
• ssh-keygen
Debugging Option
The HP-UX Secure Shell client provides the following debugging command-line option:
-v Indicates the verbose mode. When ssh is run in the verbose mode, ssh prints debugging
messages about its progress. This is helpful in debugging connection, authentication, and
configuration problems. Multiple -v options increase the verbosity of the debugging
messages.
Running ssh in Debug Mode
Following is the syntax to run the HP-UX Secure Shell client in verbose mode:
$ ssh -[v vv vvv] [2> <outputfile>]
