NSCA (Nagios Service Check Acceptor) is a means by which host and check results can be passed into Opsview Monitor from a remote source.
## Installation
The `opsview-nsca` package is available for download from:
| OS | Source |
| CentOS6/RHEL6 | https://s3-eu-west-1.amazonaws.com/opsview-customers/NSCA/opsview-nsca-6.0.0.201902071733-1.ct6.x86_64.rpm |
| CentOS7/RHEL7 | https://s3-eu-west-1.amazonaws.com/opsview-customers/NSCA/opsview-nsca-6.0.0.201902071733-1.ct7.x86_64.rpm |
| CentOS8/RHEL8 | https://downloads.opsview.com/opsview-support/opsview-nsca-6.2.0-1.el8.x86_64.rpm |
| Ubuntu14 (Trusty) | https://s3-eu-west-1.amazonaws.com/opsview-customers/NSCA/opsview-nsca_6.0.0.201902071733-1trusty1_amd64.deb |
| Ubuntu16 (Xenial) | https://s3-eu-west-1.amazonaws.com/opsview-customers/NSCA/opsview-nsca_6.0.0.201902071733-1xenial1_amd64.deb |
After installing the package on either the Orchestrator and/or Collectors you may need to amend your firewall to allow port 5667 through.
If `/opt/opsview/nsca/etc/nsca.cfg` did not previously exist, a password is randomly generated and put into the file. If you need to specify the password, edit this file and set `password` (and any other settings) as appropriate for your needs.
The NSCA daemon will not be started automatically; you need enable the configuration and reload opsview_watchdog:
The NSCA daemon will then be started and available for connections.
