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>]
Where:
<outputfile> specifies the file to which the error messages are redirected. You can use this file
to analyze the problem or to send the file to HP support if you are unable to solve the problem.
You can use multiple -v options to increase the amount and detail of the debug messages.
NOTE: You can use a maximum of three -v options to generate different levels of debug messages.
