Right, forget -v option :-)

Well, this is the output of "version 2" in my case:
Server:/usr/local/bin# check3.sh
/usr/sbin/sshd on port 22/tcp from package openssh-server (version 1:5.1p1-5)
/usr/lib/postfix/master on port 25/tcp from package postfix (version 2.5.5-1.1)
xargs: echo: terminated by signal 13
/usr/sbin/monit on port 80/tcp from package monit (version 1:5.0.3-3)
xargs: echo: terminated by signal 13
/usr/sbin/mysqld on port 3306/tcp from package mysql-server-5.0
(version 5.0.51a-24+lenny2)
xargs: echo: terminated by signal 13
/opt/splunk/bin/python2.6 on port 8000/tcp from package splunk
(version 4.0.3-65638)
xargs: echo: terminated by signal 13
/opt/splunk/bin/splunkd on port 8089/tcp from package splunk (version
4.0.3-65638)
xargs: echo: terminated by signal 13
/usr/local/bin/ruby on port 10000/tcp
xargs: echo: terminated by signal 13
/usr/local/bin/ruby on port 10001/tcp
xargs: echo: terminated by signal 13
/usr/local/bin/ruby on port 10002/tcp
xargs: echo: terminated by signal 13
/usr/sbin/collectd on port 32918/udp from package collectd (version 4.7.2-1)

is this "xargs: echo: terminated by signal 13" the output it should be?

thanks once
