There is a commercial version, but this code is open source: https://github.com/saltstack/salt I wasn't saying we use their code - although if the licence says that other open source projects can use it, then it is worth considering. It looks like it's using the Apache licence.
Kind regards,

...And looking even closer at saltstack, it's a commercial product, leading to a possible trigger of "that's ours! cross our palms with MUCH silver" (probably based on OSS, but thats' never stopped anyone).
Taking me back to "do it outside of xymon" for cleanliness sake.

The way Salt Minions authenticate and their keys have to be accepted on the Salt Master works pretty well. I don't believe they expire. It's been a while since I looked at it, so I couldn't tell you exactly how it works, but there's some information here: https://docs.saltstack.com/en/getstarted/system/communication.html Anyway, that model would probably work pretty well for Xymon, so long as the reporting client is not ephemeral.
Kind regards,

People always go for certs... And then they expire and stuff startsbreaking or alerting right and left all at once. GACK!
For real hilarity, make them expire ten years out. By that time, noone even remembers that certs were even installed or what they're for. As the home loan industry said right before the big crash, IBG, UBG (I be gone, you be gone).
From one who has had to deal with such mass silliness, take it fromme, it's NO FUN and REALLY tedious to fix.
"But I'll just use the cert for tunnel authentication" I hear yousay... If in-authentic communication (even self signed) isn't denied, do we care if it's signed really? If we do care then we deny communication/ignore messages. Now we've lost reporting links and visibility.
Some form of message authentication is probably a good idea though.Just something that doesn't expire and can be revoked as needed. gpg/pgp keys maybe, but then we get the issue of gpg/pgp key distribution/signing. Key per monitored system... Anyone want to manage THAT?
