Or, if your OS supports it, check the return code from nc -z a.b.c.d 22 to check if ssh is listening.

NAME
sa-check_spamd - spamd monitoring script for use with Nagios, etc. SYNOPSIS
sa-check_spamd [options] Options: -c secs, --critical=secs Critical ping response threshold -h, -?, --help Print usage message -H hostname, --hostname=hostname Hostname of spamd service to ping -p port, --port=port Port of spamd service to ping --socketpath=path Connect to given UNIX domain socket -t secs, --timeout=secs Max time to wait for a ping response -v, --verbose Verbose debug output -V, --version Output version info -w secs, --warning=secs Warning ping response threshold DESCRIPTION
The purpose of this program is to provide a tool to monitor the status of "spamd" server processes. spamd is the daemonized version of the spamassassin executable, both provided in the SpamAssassin distribution. This program is designed for use, as a plugin, with the Nagios service monitoring software available from http://nagios.org. It might be compatible with other service monitoring packages. It is also useful as a command line utility or as a component of a custom shell script. OPTIONS
Options of the long form can be shortened as long as the remain unambiguous (i.e. --host can be used instead of --hostname). -c secs, --critical=secs Critical ping response threshold in seconds. If a spamd ping response takes longer than the value specified (in seconds) the program will exit with a value of 2 to indicate the critical status. This value must be at least as long as the value specified for warning and less than the value specified for timeout. -h, -?, --help Prints this usage message and exits. -H hostname, --hostname=hostname The hostname, or IP address, of the spamd service to ping. By default the hostname localhost is used. If --socketpath is set this value will be ignored. -p port, --port=port The port of the spamd service to ping. By default port 783 (the spamd default port number) is used. If --socketpath is set this value will be ignored. --socketpath=path Connect to given UNIX domain socket. Use instead of a hostname and TCP port. When set, any hostname and TCP port specified will be ignored. -t secs, --timeout=secs The maximum time to wait for a ping response. Once exceeded the program will exit with a value of 2 to indicate the critical status. The default timeout value is 45 seconds. The timeout must be no less than 1 second. This value must be greater than the values specified for both the critical and warning values. -v, --verbose Display verbose debug output on STDOUT. -V, --version Display version info on STDOUT. -w secs, --warning=secs Warning ping response threshold in seconds. If a spamd ping response takes longer than the value specified (in seconds), and does not exceed the critical threshold value, the program will exit with a value of 1 to indicate the warning staus. This value must be no longer than the value specified for critical and less than the value specified for timeout. EXIT CODES
The program will indicate the status of the spamd process being monitored by exiting with one of these values: 0 OK: A spamd ping response was received within all threshold times. 1 WARNING: A spamd ping response exceeded the warning threshold but not the critical threshold. 2 CRITICAL: A spamd ping response exceeded either the critical threshold or the timeout value. 3 UNKNOWN: An error, probably caused by a missing dependency or an invalid configuration parameter being supplied, occurred in the sa-check_spamd program.
