Connecting to the IRTF Networks

1. Introduction

   RJ45 connections are available for IRTF observers & guests at HP and the summit.

   Contact the telescope staff for your connection on the summit. To avoid conflicts with other observing groups, contact the staff before to connecting your computers to the IRTF network.

   Please check with IRTF support astronomers or computer people before adopting a guest IP, to make sure it isn't already in use.

   10baseT connections are available at HP (in the offices with the workstations "wien" and "helmholtz") and the summit (ask the telescope operator).

   /usr/sbin/ping 128.171.71.60
