=> ↺ What happened with ASUS routers this morning?
When I woke up today around 6:45 AM PDT, I didn’t seem to have internet service available. My phone told me that I was connected to my Wi-Fi network, but it didn’t have connectivity. “Hmm, that’s weird,” I thought. Maybe a fiber cut in the area or something? I looked at my IRC client on my desktop Windows PC, which is nice because it records timestamps of when I lose my connection: [...]
=> ↺ Static Ad
When you launch a virtual machine on an OpenStack-managed network, the VM generally receives a random address in the active subnet. A researcher at work, however, needed a system for launching instances that have static addresses so he could preconfigure the local /etc/hosts file with all his machines.
The trick is to use set up some networking ports in OpenStack with pre-assigned IPv4 addresses and then launch the instances with the --port option rather than the --network option.
=> ↺ Having metrics for something attracts your attention to it
For reasons beyond the scope of this entry, we didn't collect any metrics from our Ubuntu 18.04 ZFS fileservers (trying to do so early on led to kernel panics). When we upgraded all of them to Ubuntu 22.04, we changed this, putting various host agents on them and collecting a horde of metrics that go into our Prometheus metrics system, some of which automatically appear on our dashboards. One of the results of this is that we've started noticing things about what's happening on our fileservers. For example, at various times, we've noticed significant NFS read volume, significant NFS RPC counts, visible load averages, and specific moments when the ZFS ARC has shrunk. Noticing these things has led us to investigate some of them and pushed me to put together tools to make this easier.
=> ↺ Country Codes in the RIPE Database
The RIPE Database is a public collection of information about who holds particular Internet Number Resources (also called whois records). These records allow network operators to contact each other to troubleshoot routing problems or for other operational needs. Most of the information in the Database is maintained by the resource holders themselves, including the inet(6)num object. However, resources managed by the RIPE NCC also have an associated organisation object, in which the country code attribute is maintained by the RIPE NCC based on the legal registration of the resource holder.
