+### Smallnet
+
+A very simple UI for managing a small /24 network. More info at this [blog post][ateijelo-smallnet]
+
+#### Sendhup
+
+For security reasons Smallnet delegates the task of reloading the configuration of *freeradius* and *dnsmasq* to a small setuid binary.
+
+To compile it, run:
+
+~~~
+g++ -o sendhup sendhup
+~~~
+
+And make it owned by root and setuid like this:
+
+~~~
+sudo chown root: sendhup
+sudo chmod 4755 sendhup
+~~~
