Re: Printer not working.
Did you try to power off the printer, remove the plug from the wall, wait 1 minute, then plug in the printer and turn it back on? I have a different hp model, but that works for me. My printer, hp 9020, complains vociferously if I just unplug it and plug it in - it wants to be turned off first, then unplugged.

Re: Looking for some WiFi AP Security Advice
My experience with self signed certs is not that great. Browsers don't like them and balk at accepting them. When added to the keyring, they disappear after a while (maybe an upgrade messes with them?) and just create lots of issues when accessing a site. I would prefer some other encryption method that can be set up and used without a lot of fiddling every time a user wants to use them.

Re: Looking for some WiFi AP Security Advice
Thanks, Anthony. I will see if the tp-link has a white list capability. If not, I will look into another AP device. There is another safety feature I forgot to mention. A physical disarm switch on the launcher, so the ignition circuit is disabled when it is engaged. However, one can forget to do that (maybe only once!), but I also don't want an attacker launching the rocket at any point. Is there anyway to encrypt the traffic between the cell phone and the web server on the Pi? To prevent someone from monitoring the various passwords?

Looking for some WiFi AP Security Advice
I am working on a project and need some security advice. The project is a wireless model rocket launcher. It consists of a Raspberry Pi 2 W (Debian Buster) connected to a daughter board with circuitry to control the current to ignite the igniter, a TP-Link Wifi AP, and a cell phone. There is a web site (apache and flask) running on the Pi that allows the user to control the circuits on the daughter board to launch the rocket. The typical location for launching the rockets is in a large field far from any buildings or trees. Typically, there is no Internet connectivity even on cell phones, but there are quite a few people attending the launch. There are also times when this launcher will be used in a more urban environment (like a high school), and I want to make the system "unattractive" to the high school students who think it would be cool to hack the launcher during a launch. I want to set up some sort of secure connection between the cell phone and the web site running on the Pi. My main concern is an attacker connecting to the web site and igniting the rocket while the user is connecting the wires to the igniter. Model rocket motors generate an exhaust gas with a temperature of ~3,000 F. Also, the igniter needs 2-4 A dc for 300 - 500 msec to ignite the rocket motor. I thought about SSL, but I would have to use a self signed certificate (assuming no Internet), and I have read that it is not that secure. I am using a long password to access the AP, a password protected login to the web site, and another password as a launch key to enable the igniter circuit and launch the rocket. I am not a network security guru, so I am not really sure what my options are. Do you have any other suggestions on how I can make this system more secure? Thanks!

I know there are a lot of articles about configuring OpenVPN on the Internet, but I am having trouble finding one that fits my situation.

The client file has this configuration, and then a lot of certificates: client dev tun proto udp remote x.hopto.org y # resolv-retry infinite nobind persist-key persist-tun I use Cox as my Internet provider, so the remote x.hopto.org y should take care of my changing IP from Cox. Is that correct? I have an account with no-ip to track my changing IP from Cox. Should proto also have TCP? What should I call this file? Is it enabled by default since it is in the clients folder? 2. Do I need to set up any special routes on my router to get from the outside to my server on port 22 for ssh? 3. In the gnome settings panel there is a VPN drop down under networking. Do I have to do anything with that? 4. What command do I use to connect to my server using the vpn?

Looking for Advice: mount --bind or symbolic link?
I tried to upgrade my computer from Ubuntu 18.04 to 20.04, and something messed up. No worries, I had a backup, so I wiped out the old 18.04 and installed 20.04. I have 2 drives in the system: 1 TB and 4TB. The 1 TB has 20.04 installed and the 4 TB has the backup from the old 18.04 system. I mounted the 4TB drive at /4TB. I think I have 2 options: * In /etc/fstab: mount /4TB/backup/home/mark /home/mark none bind * create a symbolic link from /home/mark to /4TB/backup/home/mark (assuming /home/mark is empty) Which would you recommend? Not sure if it matters, but what do I do with the system? Python development in virtualenvs (some machine learning as well), Java development, video editing, graphics editing, spreadsheets, documents, browsing, etc. Thanks!

It turns out I bought a HDD and not a SSD for the backup. Once I replaced
the HDD with a SSD, the backup only took a couple of hours.

Trouble Installing Ubuntu 22.04 from USB Stick
I have an older System 76 laptop running 18.04 in a lvm across 2 disks (1 TB and 2 TB). I have backed up all the data, and would like to install 22.04 just on the 1 TB SSD, and then replace the 2 TB with a 4 TB and the backed up data (/home/mark). I downloaded 22.04 desktop iso, verified it, installed it on a USB drive, and booted the USB drive. 22.04 comes up and I can "try" it. When I try to install it, I get as far as the 5th screen, Installation Type, where I select the 1 TB drive and hit continue. Nothing happens after that. I had selected normal installation, download updates, and erase disk. I know nothing is happening because after waiting 10 minutes on that screen, I can still boot into the old 18.04 installation, so the 1 TB drive has not changed. I did this multiple times with different iso downloads, different USB drives, and created the bootable USB on different computers. Could this have anything to do with the lvm currently installed across the two drives? Should I go into the "try" part of the USB drive, open gparted, and reformat the two internal drives, then start the installation again? All I have connected to the computer is power, an Ethernet cable (verified to be working), the USB boot drive, and a USB mouse (the internal trackpad is broken). Thanks!

Re: Electrical costs to run a home web server
Keith, All things being equal, I would use the laptop. You can disable the screen and even close the lid, although I leave mine up about 30% for cooling. There will come a time long after you install the OS that something will happen and the computer won't boot. You then need to (1) find that old monitor; (2) find the right cable; (3) find the right mouse; (3) pull out the computer from whatever corner it has been relegated to since you haven't touched it in, maybe years?; (4) hook up the monitor, mouse, etc. and diagnose the problem. With the laptop, just fold up the screen, reboot, hit f-something to get into safe boot, and diagnose the problem. The fun part is when your partner donates that old monitor to Goodwill in an effort to "clean up the clutter"if ssh doesn't work, now you are shopping at Goodwill for an old monitor. This story is based on real life experiences. Only the names were changed to protect the innocent.

OT: Looking for FOSS Recommendations for Telephone Speech to Text Devices for the Hard of Hearing
My 90+ year old mother-in-law wears hearing aids, but can not hear a phone call, even with amplification in the headset. I have seen the speech to text phones on Amazon, but the reviews say they can be slow and there is a human operator listening in on the call typing the messages. I was wondering if there are any FOSS solutions for converting speech from a phone call to text so that we can communicate with her on the phone. She does not have a cell phone and does not want to learn how to use one, so texting is not an option. She has internet and wifi in her apartment and a phone line. It would have to be super easy to use, as she is not tech-savvy. She is local, so I could set it all up for her. Thanks!

OT: Looking for Some WiFi Networking Advice
I need to upgrade my home wifi network with a high speed mesh network (primarily for better phone coverage in my house - I make a lot of video calls to the UK). I have Cox Gigablast on my wired network. The issue I am running into is that the "base" unit of the eero units and other vendors' boxes have to connect to either (1) the cable model or (2) the router and not the switch. My modem, router, and switch are all in a cabinet above my desk in the office, so (1) I don't need wifi in the office and (2) I don't relish the thought of having a wifi transmitter sitting 3 feet from my head 12 hours a day. I want to connect the wifi boxes to my wired network in a couple of different rooms away from the office. Eero (and other vendors) says the "base" unit has to act as a gateway (my router does that now), so it cannot be after the switch. Any suggestions on how I can get a high speed mesh network in my house and not take a daily showert in 2+ GHz radiation? I also want to use the wired network as the backhaul channel. Please don't start a discussion on the health effects of wifi radiation. Just assume I am so unscientific and superstitious that I believe in wifi gremlins and I don't want them invading my head.;) Thanks!

OT Need Some Help With Git
I need some help from a git user to unravel a git issue I am having. I have a local repo and a private remote repo in the cloud (not github). I am the only user. I have been using these two for a couple of years with no issues. However, I inadvertently included some large test files in some commits, and the repo grew to over 8 GB and started having issues. I went through the local repo and removed the unnecessary files using BFG repo cleaner, and now it is down to 145 MB. I thought I could just wipe out (i.e. delete) my remote repo, make a new one, and then push my local to remote and be done with it. It did not work out as I planned. I posted a detailed question on stackoverflow - https://stackoverflow.com/questions/64055979/issues-with-updating-a-fresh-remote-git-repository?noredirect=1#comment113275077_64055979 and got one suggestion, but I don't really understand what the person is suggesting. I also found this article, which seems to relate, but it is not detailed enough for me to follow it. https://www.nickang.com/2017-09-30-replace-git-branch-code/ I am hoping someone on the list who has some experience with git, can help me fix this problem.
