# Getting startedBe sure to setup your SSH keys as outlined in the manual; it's betterto log in via a real SSH client to the nodes in your experiment.The Open Air Interface source is located under `/opt/oai` on the enb1and epc nodes. It is mounted as a clone of a remote blockstore(dataset) maintained by PhantomNet. Feel free to change anything inhere, but be aware that your changes will not persist when yourexperiment terminates.To access the UE via ADB, first log in to the `adb-tgt` node, then run`pnadb -a` to connect to the UE. Use ADB commands as per normalafterward. If/when you reboot the UE, be aware that you will need toagain run `pnadb -a` to reestablish the ADB connection; wait a minuteor so for the UE to become available again before doing this.The OAI mobile networking functions should automatically start up whenyour experiment starts up. You can pull up and monitor the OAIprocesses on the `epc` and `enb1` nodes. Execute `sudo screen -ls` tosee what sessions are available. The commands for controlling serviceson these nodes are located in `/local/repository/bin`.
