How to install Windows Server 2019 from Microsoft on VMWare.
One of our open tickets on MidWest-IX is a member reporting slow speeds on their exchange port. After having them send us some data and a few e-mails back and forth we began looking at their switch port on the fabric. Right away we noticed errors on the port. After a counter reset the errors were still incrementing
19 runts 0 giants 1210 CRC 0 no buffer 1329 input error 0 short frame 0 overrun 0 underrun 0 ignored
This led us to look at our LibreNMS data for this port. A quick look shows on October 31st the port started seeing input errors.
By drilling down we are able to see exactly when this started happening
We now have responded to the customer to see if anything changed that day. Maybe a new switch, new optic, or software upgrade. By having this data available in an NMS we were able to cut down on troubleshooting by a huge margin. We now know when the issue started and are closer to the root cause of this. Without this data, we would be spending more time trying to diagnose and track down issues.
Are you running your own mail server? If so, check out this primer from the folks over at MX Toolbox. Lots of good links here.
Normally on a peering exchange, all connected parties will establish bilateral peering relationships with each other customer connected to the exchange. As the number of connected parties increases, it becomes increasingly more difficult to manage peering relationships with customers of the exchange.
However, by using route servers for peering relationships, the number of BGP sessions per router stays at two, if the IX has deployed redundant servers.
More details and review coming soon. Gi joe for size reference.
Ubiquiti launches the Ubiquiti Speedtest, the first public test network integrated with enterprise network equipment. Ubiquiti Speedtest comprises a network of test servers and built-in speed test capabilities. Reports include uplink/downlink throughput and latency. Sharing the results is easy via email or social media.
It appears you can run this on a Ubuntu server or VM. They have an installer and a docker image. You can do browser-based speed tests or their WiFiman App.
Tests may run over LAN, Wi-Fi, or mobile networks. Ubiquiti Speedtest uses Ubiquiti test endpoints and provides automated and manual test target selection. The automated selection uses a combination of geolocation and latency measurements for determining the best servers. The algorithm may use several parallel endpoints for the best measurement accuracy.
