[Nagiosplug-devel] Patch for check_ntp when checking against cisco ios ntp servers

[David Sullivan]

In it's current form check_ntp assumes it's talking to a unix ntp server and expects the 
following output from ntpq:

*192.168.1.1  .GPS.            1 u   12  256  377    14.50    0.016    2.17

Whereas the cisco ios NTP implementation returns the following:

*192.168.1.1  .GPS.            1 -  392 1024  377    22.31   -4.749    2.29

The following patch modifies the regexp to recognise - for field 5 as well as l u m or b 
returned by "normal" ntp servers.
