for serial lines

- "the other host in the same rack" with ethernet + serial cross-connected

Do note that OOB is only fully OOB if you can mess up prod completely and still reach your OOB devices, that means if a switch is involved in your IPMI setup, it should not be the main switch, but a separate one (so that one can kill the main one, and use the OOB to fix it again). That also means that you need separate connectivity (borrow an IP from a friendly ISP in the same rack) or use 4G/5G if available in the DC.

If using 4G, remember that one can do a wireguard mesh OOB to a non-own VM somewhere for OOB too. Ensure that you have ACLs and static IPs to connect from them too. Tor is also a fine option for low-bandwidth access in more hostile networks, then people need to know the onion fingerprint to get to your SSH.

In DCs you will also find opengear or airconsoles btw.

As noted, depends on requirements, budget and many more things.

Greets,

Jeroen

Hi all,

I am starting a small project with a student of the Technical School in Lausanne ETML-ES (for his diplom work), it will end up as a mobile kit for remote staging.
I would like to collect some experience from you folks, will be kept 100% anonymous.
If you agree, can you drop me an email directly and answer these questions:

- do you have Out-of-Band console management for your network equipment ?
- if no : how do you manage your network equipment ?
- if yes: which product (brand/model) ?
- if yes: which interfaces on the equipment side ? (RJ45, USB, etc..)

Thanks in advance.
For the people providing answers: I will send you the survey result without company or people's names.

Best regards
