Hi Peter,

Ever look at Opengear? They have a lot of nice OOB management devices 
(modem/3G/4G/LTE) that give you full access to the underlying Linux OS.

Happy customer.

Best,
Will

Subject: [lopsa-discuss] Out-of-Band Management Solutions

Howdy, fellow sysadmins:

We are looking for any feedback members of the list might have regarding a 
pretty common problem: reliable out-of-band access to our network when WAN(s) 
and/or site2site links go down. We currently have multiple connections at each 
office but we've run into situations where being able to use a third link to 
sneak into the network and bring things back up would have been much easier.

Currently we've been reviewing a number of different solutions -- all-in-one 
devices that are purpose-built for OOB-access to devices that are basically the 
network portion of a car computer.

We are wondering if there are any products out there that folks from the list 
could recommend we focus on that might work well for this OR could recommend we 
stay away from. We're just as happy to know what products to avoid as to dig 
into further.

Here's our list of minimum requirements:
1. Some kind of appliance that actually does the OOB connection over cellular 
3G/LTE/etc
   -- we're not opposed to using something like a NUC + MiFi, just wanted to 
avoid building custom out of the gate if there's something better and more 
reliable
   -- we're planning to put a small linux device (we're leaning Pi or NUC) to 
serve as a jump box and for features that the device itself might not have

2. must be reasonably low on power usage (<100W)
   -- this is so we can have a dedicated UPS that isn't obnoxiously large and 
still get 1+ hr runtime

3. must have a good security track record since it will live on a public 
connection unfirewalled
   -- we once ran into a small appliance that had a recursive DNS server and 
happily forwarded internal DNS queries externally and you couldn't turn it off; 
this kind of thing is simply a deal breaker for us

4. One of our offices is in London so the device must be compatible or modular 
enough that we can get on international cell networks

Nice to haves, not required:
1. central management (if it's a turn-key solution)
2. built-in vpn options
3. minimal licensing headaches preferred

Some of the product we've looked at are made by these companies:
1. Peplink
2. Cradlepoint
3. Sierra Wireless

Any thoughts from the list?  I appreciate any feedback you can provide!

Pete
