Neglected for years, compatability problems, buggy

The NSCA addon has been ignored and neglected for years. For passive checks, try NRDP instead.

I can’t imagine why NSCA is still a featured plugin on the Nagios Exchange when it hasn’t received an update in over 3 years.

The NSCA addons work, but they are buggy, crash too often and will lead to false positives on your Nagios server.

The 2.9 branch and 2.7 branch are not compatible. The 2.7 branch is still in wide use due to these compatibility issues, but it hasn’t received an update since 1997. The 2.9 branch hasn’t received an update since 2012.
