At about the same time last year, we announced that we were locking off our LInux lab “proxy” addresses behind the firewall. Due to a number of factors, this task was postponed and we are finally going to make the change on Wednesday, Sep 11.

Read the included message for details.
Note, existing CS login servers (ada/babbage/quizors) are not affected. Just the proxy addresses for the various Linux labs.

Subject: [Cat-announce] Moving Linux Lab proxies behind the firewall
To: cat-announce

In recent years, most of our Linux “lab” systems (ie: computer lab systems running Linux) have been moved behind the firewall. That means that you need to be on the VPN to connect to them directly from off campus (using ssh, for instance).

Our Linux Lab proxies function much like “aliases” that let you log into a proxy group address that lets you connect to a random computer within that group. We currently support the following proxies to computer lab Linux systems:

Proxy Name

What it gives you

particlelab.cs.pdx.edu

random system in CS Particle Lab (FAB 88-09)

penguinlab.cs.pdx.edu

random system in CS Penguin Lab (FAB 88-10)

linuxlab.cs.pdx.edu

random system in CS Penguin or Particle labs

fab-linux.cecs.pdx.edu

random Linux system in FAB 55-17

intellab-linux.cecs.pdx.edu

same as fab-linux.cecs.pdx.edu

As a legacy behavior, these proxies are currently directly accessible from the Internet, although the computers they access are behind the firewall.

We will soon be moving these proxies behind the firewall. This means that in the future, you will need to be on the VPN to directly connect to them from off campus.

Note: this will NOT affect the current remote access capabilities of:

  • linux.cs.pdx.edu
  • ada.cs.pdx.edu
  • babbage.cs.pdx.edu
  • linux.cecs.pdx.edu
  • ruby.cecs.pdx.edu
  • rita.cecs.pdx.edu
  • quizor systems
