Heh. Those of us on NANOG have seen yet another explosion of traffic and rehashed arguments and digressions on this over the past month. https://mailman.nanog.org/pipermail/nanog/2021-November/thread.html -- Julian Y. Koh Director, Telecommunications and Network Services Northwestern Information ...

We aren't doing exactly what you describe at the moment. However, on one of our previous VPN platforms, we were using the Pulse Secure (previously Juniper, previously Netscreen, previously Neoteris) VPN posture assessment features (at least at the time it was called Host Checker) to do validation of ...

I'm with Hunter with respect to the fact that running servers in the residence halls back when I was a student in the 1990's was a huge boost toward my career in IT as well. But that was the 1990's - students don't need a wired port to do that anymore. Not only are there services like ngrok, but academic ...

If we have an ATS in play, it's because there's a generator in the mix. For access layer closets and such, the UPS typically feeds one set of power supplies in the closet switches, and we run utility power to the other set of power supplies, as my Big Ten brethren also just said. :) -- Julian ...

We deactivated all of our residence hall wired ports a couple summers ago and went with activation on request. Student Affairs is restricting activations only to members of the eSports club as well. Prior to that for a few years, residence halls that were brand new construction or undergoing gut rehabs/renovations ...

We've switched from the Blackboard Connect service to RAVE. Seems to work fine. If you'd like to talk to the folks in our Public Safety department who drove that all forward let me know. -- Julian Y. Koh Director, Telecommunications and Network Services Northwestern Information Technology 2020 ...

Just closing the loop here - yesterday we completed our last upgrades to the 8.7.1.6 GA code from Aruba, and all has been going well. We've got all telemetry/monitoring/DPI/firewall functions turned back on at this point too. Thanks again to everyone for help and input on this one! -- Julian Y. ...

Adding a little more detail to Chris' message: We've been running eduroam successfully for years now in parallel with the "Northwestern" branded SSID. We can assign local NU users to the same role across both SSIDs, and the same auth method is used for both. We started pushing people to make the switch ...

C Build means a custom build that is usually rolled for a specific customer or subset of customers to address an emergent issue. Typically C builds haven't gone through the full suite of regression / field testing that a GA (general availability) build goes through. Our understanding is that 8.7.1.6 ...

Dang, Richard beat me to first post for this group on the new platform. :) :) :) As of early this morning, we have our entire Chicago and Evanston campuses all upgraded to the 8.7.1.5 C build from Aruba, and things have been working very nicely in terms of load balancing across controllers. 8.7.1.5 ...

If you're already looking for text in the subject line, "Cybersecurity :" seems to work fine as a matching string. And heck, if this new system gets rid of all the subject line munging that other systems do with respect to adding [EXTERNAL] and [EXT] and all of that other stuff, I'll consider that an ...

OK, I tried to respond without top posting with the following: My filters for all the EDUCAUSE groups didn't really change that much. Each group has a distinct string in the subject, so just matching on the From: address and then adding a condition to look for the string in the subject appears to ...
