Today we release a new extension: shorewall-monitor for Xymon:
If you run shorewall or shorewall-lite on your systems
this may help you monitoring the state of your firewalls. It is installed as a
local extension on the client and reports the state of
metrics about the currently active ruleset (version, hashes, …) and
optionally even the full ruleset.
Especially in environments with many (satellite)
Xymon can serve as a central point of information about their states and
rulesets with this extension.
For more details see the project-page: shorewall-monitor for Xymon.
