Want to talk to your local CVS pharmacist, but can’t or don’t want to wade through the endless IVR? Use 8001 through 8005 to ring the pharmacy extension directly as soon as the IVR picks up. 8001 is usually enough, but YMMV.

I cam across this on macOS 13.5 (Ventura). Basically Shimo would connect, but then it could not pass any traffic. A reboot fixed it every time, but was painful at times. First thing I did was check the Preferences and enable “Reset Network Configuration when Shimo is terminated” under the Advanced tab. That and pushing […]

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:

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 […]

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 […]

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:

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. […]

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 […]

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 […]

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.
