ssh-probe2(1)ssh-probe2(1)NAME
ssh-probe2, ssh-probe - Locates Secure Shell servers from the local
network
SYNOPSIS
ssh-probe2 [-t timeout] [-r] [-s] [-d debug_level] [addresses ...]
OPTIONS
The amount of time (in seconds) that the ssh-probe2 command waits for
server replies before exiting. Makes the output more readable than the
raw list format suitable for scripts. Inhibits output. The success of
the ssh-probe2 command can be concluded only from the exit value. In
this mode, the -r option has no effect. Prints extensive debug infor‐
mation to stderr. The debug_level is either a number, from 0 to 99,
where 99 specifies that all debug information should be displayed, or a
comma-separated list of assignments (i.e., ModulePattern=debug_level).
This should be the first argument on the command line.
DESCRIPTION
The ssh-probe2 command sends a query packet as a UDP datagram to
servers and displays the address and the Secure Shell version number of
the servers that respond to the query.
RETURN STATUS
The ssh-probe2 command returns one of the following exit values. This
can be useful in scripts. The broadcast was sent, and at least one
reply was received. The broadcast was sent, but no replies were
received. An unspecified error has occurred. This is for errors not
listed previously.
