Although the script worked flawlessly locally, I had to edit it as follows to correct the logic:
if [[ "$eroutes" -eq "2" ]]
then
echo "OK - All 2 tunnels are up an running"
exit $STATE_OK
elif [[ "$eroutes" -gt "2" ]]
then
echo "WARNING - More than 2 ($eroutes) tunnels are up an running"
exit $STATE_WARNING
else
echo "CRITICAL - Only $eroutes tunnels from 2 are up an running - $(location)"
exit $STATE_CRITICAL
fi
Besides this, I had to do the following to fetch the results via NRPE plugin remotely:
chown nagios /var/run/pluto/pluto.clt
Now I'm able to view the proper results over my NAGIOS monitoring console.
Hope this helps someone.

Hi,
we want to use this script to remotely check VPN tunnels' status, executing this script with NRPE on an IPcop host.
But there is no command which in our IPcop v2.1.9, although http://www.cobin.de/binary.php has a locate addon. We therefore replaced "which " with the full paths of files in check_ipcop2.sh.
Also, in the scripts function check_connection(), in the line:
eroutes=`$IPSECBIN whack --status | grep -e "IPsec SA established" | grep -e "$2" | wc -l`
we believe the $2 should actually read $1.
With these modifications, we were able to use the script locally:
$ /var/ipcop/addons/nrpe/plugins/check_ipsec2_mod.sh -c tunnelname
OK - tunnelname Connection is up and running
Sadly, the same check done remotely on the Nagios host, with that same commandline above defined for NRPE as command check_tunnelname, does return a different result:
/usr/local/nagios/libexec/check_nrpe -H ipcop-hostaddr -c check_tunnelname
CRITICAL - tunnelname Connection is down
This may only be a user rights problem, as the local test was done as root, but the nrpe service runs as user nagios. But there is no command su or sudo in our IPcop v2.1.9 (hence no /etc/sudoers), and we know of no suitable addon.
