Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

I only have one issue with the post.
The conclusion says use long random SNMP community strings.
Ideally you should be using SNMPv3 because snmp1/2/2c are all clear text.
Apart from that, nice article
You are absolutely correct, thank you. Sadly a bunch of devices still don't support it, even in 2025 (like my microtik switch) for example. I will absolutely add a note about that though, thank you!
Updated the post to reflect your feedback here. Thank you!
Really? SNMPv3 was ratified in 1998. How does anyone take them seriously without it?
And IPv6 was codified in RFCs and first addresses issued in 1999 but look where we are now. I'd bet your corporate network doesn't use IPv6 still. It's unfortunate, but sometimes the wheels of change are slow.
My home, work, and mobile networks are all dual stacked.
This is a difference in kind. IPv4 live was extended with Nat and cgnat, but nothing equivalent came for snmp.
Hey good for you, that's awesome! My home network is also dual stacked.
You're right about the apples to oranges comparison, but it's not so wildly off, because the commentary is on adoption of new standards, regardless of bolt-on "fixes." Unauthenticated SNMP went through three revisions prior to adding authentication and encryption support.
