  • VLANs are an extension of the Ethernet technology, and operate on the link layer (OSI layer 2). They are handled by switches. VLANs can belong to different subnets, and communication between them requires routing, which happens on the network layer (OSI layer 3) on either routers or layer-3 switches, but VLANs themselves are handled by switches.

    I recommend Network Chuck on youtube, his videos are very noob-friendly.


  • It’s definitely a beast at the best of times, but the scriptability is great.

    Just a few weeks ago I used it to deploy a custom Win10 image to several hundred computers in a very heterogenous environment in lite-server mode (basically PXE with extra steps). It took three of us sysadmins several days to figure out why it wasn’t working, several more to write a script that could handle every scenario. Some computers had SATA SSDs, some NVMe, some both, some SSD+HDD, the block device names (sda, sdb…) were never consistent, and some reported its HDDs to sysfs as SSDs. I ended up dissecting the ISO and came up with a solution that only required a single Enter key to start and did everything else automatically.
