Steps for setting up openairinterface on orbit

1. hostnames
   1. append the following lines to /etc/hosts:

      127.0.1.1 nano.orbit-lab.org nano
      127.0.1.1 hss.orbit-lab.org hss
      

   2. set /etc/hostname to nano
   3. hostnamectl may be a workaround
   4. to check, you must use getent hosts name
      1. getent uses gethostbyname, while host and nslookup query DNS directly
   5. use script to append items to db
      1. mmeidentity for user must match index of mme used
      2. imsi specified for both user and pdn
      3. specify user key with UNHEX function
      4. edit line at bottom of hss.config to enable 001 01 plmn
         1. fqdn defined in spec
