SSH-PROBE2(1) SSH2 SSH-PROBE2(1)
NAME
ssh-probe2 - seeks Secure Shell servers from the local
network
SYNOPSIS
ssh-probe2 [-t timeout] [-r] [-s] [-d debug_level] [-V ]
[addresses...]
DESCRIPTION
ssh-probe2 sends a Secure Shell server query packet as a
UDP datagram to the given broadcast addresses. Servers
that allow UDP queries respond to the query and ssh-probe2
prints the addresses and version numbers of these servers.
OPTIONS
-t timeout
Timeout in seconds. This is how long the program
waits for server replies before exit.
-r Makes the output of the program more readable than
the raw list format suitable for scripts.
-s Inhibits output. The success of the command can only
be concluded from the exit value. In this mode
option -r has no effect.
-d debug_level
Prints extensive debug information to stderr.
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
of the format ModulePattern=debug_level, for example
"*=10,sshd2=2". This should be the first argument on
the command line.
-V Print version information.
RETURN STATUS
ssh-probe2 returns one of the following exit statuses.
This may be useful in scripts.
0 The broadcast was sent, and at least one reply was
received.
1 The broadcast was sent, but no replies were
received.
-1 An unspecified error has occurred. This is a
catch-all for errors not listed above.
