 Because the munin server client model is so basic you can find node software for most operating systems.
 I've run it successfully on [freeNAS](https://www.truenas.com/community/threads/install-munin-node.79224/#post-549934) but you can try a [windows](https://github.com/munin-monitoring/munin-node-win32) node as well.
 
+When I say *simple* I mean *really simple*.
+For those who like digging a bit deeper, you can connect to the munin node over telnet.
+From a terminal on the master, or any IP address that is in the allow list of the node, you can do the following.
+
+```
+waldek@muninserver:~$ telnet 10.8.0.1 4949
+Trying 10.8.0.1...
+Connected to 10.8.0.1.
+Escape character is '^]'.
