--- title: "Check installation" date: 2019-12-30 weight: 40 description: > 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 ``` Now you should be able to ping our server! ```bash $ oping -n ouroboros.rocks.oping ```
