Hi, I just want to bring to your attention the below talk (I am too lazy to re-write the whole email for this slightly different audience). Takeaway: We'll see a lot of ECN enabled traffic in a few months. This shouldn't be a problem. I've been doing it to all my machines for 3-5 years with

Setting Up a Looking Glass

What's out there for setting up your own looking glass? I saw lots of lists of dead projects or projects that hadn't received any love in years. Being as most the people I work with don't run Cisco, Juniper, etc. for routers, likely having those capabilities with the LG would be nice. -

Re: Setting Up a Looking Glass

I totally agree, it would be awesome if it had routing table lookups / BGP queries. We also have a LG running the original system, https://github.com/telephone/LookingGlass. It would probably be pretty simple to add in BGP options. There's a nice system called bgplg that is part of OpenBSD.

Hi everyone, I know this is slightly off-topic, but since it's still related to the list, I thought I'd give it a try. I am wondering what systems are out there (open source, preferably) for data collection and processing of hardware health data (temperature, CPU clock, fan speeds, etc). Ideally b
