Why the fuck they don’t just have a button to do this like VMware I don’t know. Probably a German thing. Either way there is no GUI way to enable a maintenance mode, BUT there is a sneaky and useable way from the command line. To disable “start at boot” without manually changing the VMs […]
Increase an Ubuntu VM disk size on a Proxmox host live
Step one is to update the disk size for the VM. This is easily done in the GUI. Select your VM on the left, click on “Hardware,” choose the virtual disk you want to resize, and then select the “Disk Action” menu from the top. From here select “Resize” as per the below: This should […]
Talk to CVS pharmacy
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.
Shimo can connect, but does not pass traffic after a while
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 […]
Test your Proxmox email setup!
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 […]
