Greetings, all, and Happy New Year.

For out-of-band access, we have a few of these in some data centers
and they work nicely:

They solve three use cases:

1) They allow us to ssh into our servers over 3G/4G when the standard
network is down.
2) If there are iDRACS or managed power, we can get console access
and/or power management, again, when the normal network is down.
3) They they allow us to remotely control our networking gear, having
full access while we swap configs or reboot.

These devices are handy, but can be a bit pricey.  So these devices
tend to be used more by our mid- to high-end clients.

Yet, we have clients with simple setups, just one or two servers,
maybe in a data-center or maybe stuffed under someone's desk.  For
them, I would imagine a cell phone with a USB tether would work
sufficiently to ssh into their servers remotely.  That assumes the
cell phone can run an ssh server or connect to a VPN.  Just ssh into
cell phone then ssh to server, or even just do port forwarding
straight to the server.

A small step up would be an older netbook, running SSH or a VPN, again
tethered to a cell phone and connected to the server over both
ethernet and serial.  For console access or power control, the netbook
can be connected to a single server KVM, like the Spider:

Has anyone done something like that or know of similar solutions for
remote OOB access to servers?

Regards,
- Robert
