Debugging the Clients

The ssh2 application can be debugged by using the -d option. The scp2 and sftp2 applications can be debugged by using -D option.

Debug level 4 is usually sufficient. For more detailed information, debug level 7 can be used.

Debugging Interactive Sessions

When using interactive sessions from OMVS, Telnet, or SSH shells, debug information is displayed on screen. Debug option is entered to the used command, for example:

ssh2 -d 4 user@server

sftp2 -D 7 user@server

Debugging Non-Interactive Sessions

Similar options can be entered also to JCLs. When running clients from JCL, debug information is stored to a defined STDERR file.
