+Have you ever wanted a proxy server that you can run on a toaster (literally)? Well, enter today's setup, Microsocks on NetBSD. Microsocks is a simple, fast and efficient SOCKS5 server. NetBSD is a highly portable UNIX system that you can literally run on a toaster.

+
+## Prerequisites
+* Something running NetBSD
+* Internet connection
+
+## Getting microsocks
+Microsocks is not in the NetBSD repositories as far as i can tell, so we'll just compile it.
+```
+git clone https://github.com/rofl0r/microsocks
+cd microsocks
+make
+make install
+```
+And now we have installed Microsocks. Yay! You could just run it in a `screen` or something, but that's not very practical and actually pretty lame, so we'll setup an rc script.
+
+## Setting up the rc script
+Firstly, open /etc/rc.d/microsocks with your preferred editor (I use `Vim` BTW) and add the script below
+```sh
+#!/bin/sh
+#
+# PROVIDE: microsocks
+# REQUIRE: DAEMON
+
+. /etc/rc.subr
+
+name="microsocks"
+rcvar=$name
+command="/usr/local/bin/microsocks"
+pidfile="/var/run/${name}.pid"
+start_cmd="microsocks_start"
+stop_cmd="microsocks_stop"
+
+microsocks_start() {
+    if [ -f "$pidfile" ] && kill -0 $(cat "$pidfile") 2>/dev/null; then
+        echo "$name is already running."
+    else
+        echo "Starting $name..."
+        ${command} &
+        echo $! > "$pidfile"
+        echo "$name started with PID $(cat "$pidfile")."
+    fi
+}
+
+microsocks_stop() {
+    if [ -f "$pidfile" ]; then
+        echo "Stopping $name..."
+        kill -TERM $(cat "$pidfile") && rm -f "$pidfile"
+        echo "$name stopped."
+    else
+        echo "$name is not running."
+    fi
+}
+
+load_rc_config $name
+run_rc_command "$1"
+```
+
+Direct your attention towards line 10. There we have the command that starts Microsocks. It doesn't necesarrily need arguments, as such, we can leave it as such, but that's not reccomended. Consult [this page](https://github.com/rofl0r/microsocks/blob/master/README.md#command-line-options) for more information on what arguments you can use.
+
+Now to test everything is working, you can use this command:
+```
+service microsocks onestart
+```
+If you're able to connect to your proxy, you've configured it properly. We can now enable it in `/etc/rc.conf`, where we'll append:
+```
+microsocks=YES
+```
+And now we can restart and you'll see that our proxy is still alive.
+
+## Conclusion
+NetBSD is pretty cool.
