+  Check if ouroboros works.
+draft: false
+---
+
+To check if everything is installed correctly, you can now jump into
+the [/docs/Tutorials](tutorials) section, or you can try to ping this
+webhost over ouroboros using the name _ouroboros.rocks.oping_
+
+Our webserver is of course on an IP network, and ouroboros does not
+control IP, but it can run over UDP.
+
+To be able to contact our server over ouroboros, you will need to do
+some IP configuration: to tell the ouroboros UDP system that the
+process "ouroboros.rocks.oping" is running on our webserver by adding
+the line
+
+```bash
+51.38.114.133      1bf2cb4fb361f67a59907ef7d2dc5290
+```
+
+to your /etc/hosts file (it's the IP address of our server and the MD5
+hash of _ouroboros.rocks.oping_).
+
+Here are the steps to ping our server over ouroboros:
+
+Run the IRMd:
+
+```bash
+$ sudo irmd &
+```
+Then you will need find your (private) IP address and start an ouroboros UDP
+daemon (ipcpd-udp) on that interface:
+```bash
+$ irm ipcp bootstrap type udp name udp layer udp ip <your local ip address>
+```
+
+Now you should be able to ping our server!
+
+```bash
+$ oping -n ouroboros.rocks.oping
+```
