Troubleshooting and Solution

  • Tried connecting manually with ssh command
    • Same result
  • Error: No Route to Host even they can ping or traceroute the server
  • Contacted Fermilab Service Desk and opened a new ticket as incident
  • Problem solved once Network Services updated the ACL router to accept hostname as
    • 200.1.20.169…nat-sj-labinf2.campus.utfsm.cl
  • This is a temporary solution, we need to find a way to generate constant hostname everytime
