AuxTel Remote Computer Access

Instructions

Computer setup

  1. Send MAC addresses for computers you want to install in the AuxTel dome to Patrick Ingraham. He will create a Jira ticket (you can do this instead, if you're comfortable with Jira tickets) asking for DHCP reservations on RubinObs-LHN wifi.
    1. Note: it is worth adding your personal computer to RubinObs-LHN as well, because then you won't have to VPN into nublado or Chronograf while you're on the summit.
  2. Someone will complete the ticket, giving you a password to log onto the wifi, and your static IP address.
    1. Note: if it takes a while for this step to be completed, you can log into the computer into LSST-WAP using your personal credentials, and ssh in remotely on the summit or using VPN. This isn't a permanent solution, but it can work for a few days if you want to take data right away.
  3. Log onto RubinObs-LHN. The DHCP reservation should automatically fill in the new IP address.
  4. You can now remotely access the computer using a summit wifi network or a VPN when you're not on the summit. 
    1. For instance, with the Mac mini 2 listed below, this looks like: 

      ssh stubbslab@auxtel-macmini02.cp.lsst.org

VPN setup

  1. Submit a jira ticket asking for VPN access using the procedure described here: https://ittn-045.lsst.io
  2. Once the ticket is complete, you will be sent an email with the VPN config file you're supposed to use and you will follow the instructions here: VPN DOC.pdf
