Steps for setting up openairinterface on orbit

1. kernel
   1. install kernel 4.7.7
   2. issues with changing kernels on xen vm
2. 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. GENI workaround
      1. on every boot:
         1. append to etc/hosts
         2. delete etc/hostname
         3. run hostnamectl set-hostname nano
         4. logout and back in
3. 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
