Restrict Access by Remote IP Address¶
The extension configuration of the TYPO3 Nagios® extension contains an input field that holds a comma-separated list of IP addresses and/or fully qualified hostnames of all Nagios® servers which may retrieve information about the TYPO3 instance.
Comma-separated list of IP addresses
Comma-separated list of fully qualified hostnames
If the IP address or fully qualified hostname of the Nagios® server which initiates the requests to TYPO3 is not listed here, an access denied message appears (and the Nagios® server interprets this as a WARNING, CRITICAL or UNKNOWN condition, depending on its configuration):
# Nagios TYPO3 Monitoring Version 2.1.3 – https://schams.net/nagios # ACCESS DENIED MESSAGE:access denied
Access to the output of the extension is also denied, if the input field has been left empty, or an insecure value such as
*.*.*.* is used.
