Linux

For various reasons, sometimes it is useful for a hypervisor to access data served by a virtualized guest system. In this example, it's Proxmox accessing NFS shares on a TrueNAS virtual machine. TrueNAS could just as easily be replaced with Openmediavault or any other NAS server, but the concept of recursive storage access remains the same. NFS in this example could also be replaced with iSCSI, or even SMB.

Recently, I needed an LTE backup at a secondary home location with an unreliable primary internet connection. I was somewhat bewildered by the plethora of options available. I saw a weatherized Seriallink SLK-e940 on eBay for a very nice price, so I looked up the details on it. I found (from the help screenshots) that it appeared to run a modified version of OpenWRT. The image the seller provided showed inside the unit a mini-PCIe Quectel EC25-AF LTE modem, which I knew had good Linux support.
