Table 20 lists the information that is displayed for the -v, -vv, and -vvv debug options.
Table 20 Debug Information for -v, -vv, and -vvv Options
Details DisplayedDebug Option
-v
• The Identity File
• The “Authentication succeeded” message
-vv
• All the -v messages
• The private key bit set
-vvv
• All the -v and -vv messages
• Details such as authmethod_lookup and authmethod_is_enabled
The following sample debug messages show the level of detail displayed for the same HP-UX
Secure Shell connection, using the -v, -vv, and -vvv debug command-line options.
• Following is the output for the -v command-line option:
debug1: Reading configuration data /opt/ssh/etc/ssh_config
debug1: Connecting to localhost [127.0.0.1] port 1111.
debug1: Connection established.
debug1: permanently_set_uid: 0/3
debug1: identity file /.ssh/id_rsa type 1
debug1: identity file /.ssh/id_dsa type -1
debug1: Remote protocol version 2.0, remote software version OpenSSH_4.4p1-hpn
• Following is the output for the -vv command-line option:
debug1: Reading configuration data /opt/ssh/etc/ssh_config
debug2: ssh_connect: needpriv 0
debug1: Connecting to localhost [127.0.0.1] port 1111.
debug1: Connection established.
debug1: permanently_set_uid: 0/3
debug2: key_type_from_name: unknown key type ’-----BEGIN’
debug2: key_type_from_name: unknown key type ’-----END’

debug1: Connecting to localhost [127.0.0.1] port 1111.
debug1: Connection established.
debug1: permanently_set_uid: 0/3
debug3: Not a RSA1 key file /.ssh/id_rsa.
Interpreting the Debug Output
Use the HP-UX Secure Shell debug output to analyze problems. The debug output describes the
various stages of an HP-UX Secure Shell connection.
This section provides sample debug output for an HP-UX Secure Shell client that uses public-key
authentication.
NOTE: Annotations are highlighted in bold and marked with >>>>. HP-UX Secure Shell does
not display these annotations on the console as part of the debug output. Annotations included
here are for your information only.
When an HP-UX Secure Shell client connects to the HP-UX Secure Shell server in verbose mode,
the following output is displayed:
# ssh -v <server_name>
