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.

no. The default port is fine. Changing the default port does nothing for security. It only stops some basic crawler, when you are scared by crawler, then you should not host anything on the internet.
The volume on 22 will be a lot higher than a non default port. With 22 open my router was basically getting DDOS’d at times
Agreed. Anyone who thinks it's ok to just expose ssh on 22 to the internet has never looked at their logs. The port will be found in minutes, and be hammered by thousands of login attempts by multiple bots 24/7. Sure you can block repeat failed logins, but that list will just always be growing.
Then using something like fail2ban to block bad acting connections is far more effective and you even get a security benefit out of it.
Also, when a few scripts try to connect via ssh DDOS your router then something is messed up. Either a shitty router from 20 years ago or you have a Bandwidth lower than 100kbps.
I have fail2ban running on the server itself, also it was a lot more than “a few scripts”
It's not fine. Easiest way to rack up utilization on your server is getting hits on all the default service ports. Change that port to any unprivileged port to avoid that somewhat. Not every bot crawler is doing port scans on random non-commercial and unidentified IP space.
What you're describing is security through obscurity, but switching from the default port has other benefits like the above.
Getting "hit" is nothing to worry about by automated scripts. All it does is keep your logs a little bit cleaner. Any attack you should actually worry does not care if your ssh is running on 22 or 7389.
