Table 24 LogLevelFacility Values (continued)
DescriptionValue
Specifies a higher degree of debug level than debug1. Specifying DEBUG1
is similar to specifying a -dd or -vv on the command line, while invoking
sshd.
DEBUG2
Specifies a higher degree of debug level than DEBUG2. Specifying DEBUG2
is similar to specifying a -ddd or -vvv on the command line, while invoking
sshd.
DEBUG3
The DEBUG and DEBUG1 arguments are equivalent. The DEBUG2 and DEBUG3 arguments specify
higher levels of verbose output.
The default setting is INFO.
For example:
LogLevel FATAL
MACs
Use this directive to specify the Message Authentication Code (MAC) algorithms in order of
preference. SSH-2 uses the MAC algorithm for data integrity protection. Multiple algorithms must
be comma-separated.
The default setting is hmac-md5,hmac-sha1, [e-mail],hmac-ripemd160,
hmac-sha1-96,hmac-md5-96, hmac-sha2-256,
hmac-sha2-256-96,hmac-sha2-512,hmac-sha2-512-96.
For example:
MACs hmac-md5, hmac-md5-96
NoHostAuthenticationForLocalhost
Use this directive to specify whether the home directory is shared across hosts. In this case,
localhost refers to a different host on each of the hosts, and the user receives warnings about
changed host keys. However, this option disables host authentication for localhost.
The default setting is yes.
For example:
NoHostAuthenticationForLocalhost yes
NumberOfPasswordPrompts
Use this directive to specify the number of times HP-UX Secure Shell prompts before it stops trying
to authenticate the users.
The default setting is 3.
For example:
NumberOfPasswordPrompts 3
PasswordAuthentication
Use this directive to specify whether to use password-based authentication.
The default setting is yes.
For example:
PasswordAuthentication yes
PermitLocalCommand
Use this directive to specify whether to allow local command execution through the LocalCommand
option or use the ! Ns command escape sequence in ssh(1).
The default is no.
