Or don’t. I don’t care. Fuck you. If you decide to not get fucked by too many drives dying and killing your Ceph cluster because you missed SMART errors the command to run to check end-to-end is:

mailcow: Confirmed A record with IP xxx.xxx.xxx.xxx, but HTTP validation failed
Found this happening in my new mailcow installation and could reproduce following the steps here https://docs.mailcow.email/post_installation/firststeps-ssl/#lets-encrypt-out-of-the-box to re-run the ACME plugin. Found lots of others complaining about this and recommendations to disable IP and HTTP checks. Don’t do that! Instead fix your NAT reflection rules so that your containers can talk to your external IP […]
Changing USG-3P WAN static IP aka “There was an error saving the Primary (WAN1) network. IP xxx.xxx.xxx.xxx is used as NAT outband at configuration Default.”
Not sure why this is an issue that Ubiquiti has left out there, but if you try and change the static IP address the UniFi controller will puke with the above error. Apparently there are a bunch of different workarounds, but the simplest (to me at least) seems to be logging into the USG directly […]
Enable GigaBeam SNMP
No idea why Ubiquiti can’t put this into the GUI, but whatever. Thanks to IncrediGeek for the tutorial. https://www.incredigeek.com/home/configure-airos-snmp-settings-over-ssh/ Basic steps:
Don’t be a fuckup; fuckup (that’s not where check_sender_access goes!)
So recently some Russian cunt(s) started relaying email through my postfix server. I finally figured out I had a check_sender_access in my smtpd_helo_restrictions AND smtpd_sender_restrictions. With entire domains listed spammers found one of the domains to send from and then used my server as an open relay. -Don’t put entire domains in sender_access as OK. […]
Honda Odyssey can’t idle on downhill slope
In another absolute WTF; if you have a Honda Odyssey, don’t try and run it on a downhill slope. The fuel pump is installed in such a configuration that the reservoir will empty before it actually pumps more gas from the tank. Net result is the car will stall and cannot be started until you […]
SNMP packet too large
Oh FFS. So I’ve been messing around with LibreNMS and trying to setup a NTP server using a PPS signal and have LibreNMS monitor that. Got stumped on the following error: WTF does that mean? Welp, I didn’t have much luck with the ole Goog aside from reading a RFC. Basically the SNMP agent spits […]
Diag instructions for ice maker
Looks like there are 2 main kinds (at least that I have.) One doesn’t give you much to go on the other has lots of test points. This is obviously the latter.
Some aliases (Docker on M1 Mac, sudo Touch ID, etc.)
Got tired of recreating a docker line so I could run some linux commands (looking at you Yafuflash) from within the terminal. Didn’t seem like a good use of the Compose either. Apple kills this off after every update, but being able to use Touch ID for sudo instead of a password is Tier S […]
Monterey 12.3/12.3.1 Exchange/Office365 calendar stops syncing
WTF Apple? Why is this shit necessary. Anyway you can just add the below to your crontab and you shouldn’t have the problem anymore. Basically it restarts the iCal daemon every hour.
