If I correctly read the links you sent, the latest kernel has that CVE covered. But another remote host seems to have the same problem. Each host comes from a different provider and had slightly different default pinnings in '/etc/apt/sources.list'. I'll double-check my pinnings. -Tom

Solution for KVM via a cat 5 connection
Has anyone had experience using a KVM setup (at least one HDMI and two USB ports) and using cat 5/6/7 between user and the computer? I don’t need to handle multiple computers or high-def video movies, just programming and office work. I need a bit more distance from my computer which must stay in a closet, and conventional KVM equipment won’t work. If so, I would appreciate knowing what brand and model devices you are using. Thanks so much. -Tom

Yes, I've investigated that a bit. I had the same trouble with my labels at a local UPS store. The owner insisted his printers are in top shape.

Set my desired path for users in file /etc/environment $ cat /etc/environment PATH=/opt/rakudo/bin:/opt/rakudo/share/perl6/site/bin:/usr/local/bin:/usr/bin 2. I put the identical path in the usr PATH entry in file /etc/profile 3. I copied my .profile file to .xsessionrc. The result was, regardless of login method, as a normal user I had the same PATH (plus any changes from my ~/.profile file). 4. I modified the root PATH entry in file /etc/profile When I became root via "sudo -s" I got root's path from /etc/profile. When I became root via "sudo -i" I got the desired PATH change from root's ~/.profile. So far, I'm a happy camper! ANOTHER LESSON LEARNED While I was experimenting with the desktop settings, I stupidly and blindly added an exit line to cut out some 20-year old cruft in the end of the .profile file and all of a sudden I lost my xterms and couldn't find a way to edit the broken file. Fortunately, I had emacs as one of my menu items: I chose the GUI version and was able to repair the .profile file successfully. Maybe another editor would have worked, but I'm not going to experiment with that any time soon! -Tom

You do not understand the problem, Andy: Debian's package version of raku is over two years old, and it is NOT installed by default. My script uses that raku as a bootstrap to update to the latest release provided as a Debian package format similar to the manner in which PostgreSQL can be maintained in its latest state with an out-of-Debian package location. Perl, on the other hand, is very current, installed as a default Debian package, and not changing as fast as raku (improved releases almost every month). Python is its own weird thing which I ignore as much as possible. Cheers! -Tom

I failed to say my program is a bit more complicated: 0. It's executed by 'root'. 1. It uses 'raku'. 2. During its operation, the location of the 'raku' version to be used after it completes changes from '/usr/local/bin' to '/opt/rakudo-pkg/bin'. 3. Due to requirement 2, I don't think it's safe to attempt to overwrite current executables with a symlink to new executables of the same basename. I think I need to have the program change all the path-affecting files specified by Greg and others so that PATH includes both locations with the new location coming before the original location. Then the script can safely remove the original version. -Tom

I'm trying not to be a fool--that's why I'm checking with the Debian community. I'm sure I was too casual in my comments.

In effect, I will doing that. I'm in the process of automating non-package installation of Raku on modern Debian hosts.

Their support is active (last release was this year), so I'm hoping for a fix. In the meantime, I do have the two alternatives: (1) scan to USB drive or (2) use my Windows box. Since I'm unhooking my KVM switch setup to make my wife happy (she's a neat freak and I'm not), I'll have to manually unplug KVM cables from the Debian box to hook up them up to the Windows box, so laziness and the desire for weening from Windows will probably dictate option 1. -Tom

I apologize. I was not referring to stealing, and I haven't read the details in the terms of use. What I should have asked was: "is a single query in the script okay?"

memtest86
Here I am again seeking help. I have used memtest86 long ago when I burned it on a CDROM disk. I see that it's a Debian package, and I installed it. Now I see memtest86 on my boot choice screen, but selecting memtest86 does nothing. I assume I probably have to add something to the grub2 menu to use it. I have searched for how to do that, but all I've been able to find are instructions on how to use it from a bootable USB thumb drive. My grub/boot foo has disappeared. Any help on using the installed memtest86 is greatly appreciated. As a fallback, I will go the USB route if I have to, :-( Cheers! -Tom

We have a Raku module that uses "xclip" during use on a computer with a monitor. We need to test it with Github workflows which does not have a graphics device.

Yes, and they are uncommented and set to 'no'. So far all seems to be working. Now I need to study and understand those sleep options. I also realize I didn't report some other details. I have three hosts (Debian PC, Window PC, and Debian laptop) connected to a single monitor, keyboard, and mouse via a KVM switch. The other day, when I finally emailed for advice, I had noticed the following: When switching the KVM between the Win and Deb hosts, I could see the mouse was not getting power (no sensor light) nor was the keyboard or monitor screen. So that is probably why I could not wake up the Debian PC by stirring the mouse or hitting a key. My conclusion: I need to find out which sleep modes turn off power to the external input devices. -Tom

Sleep: out of control
My main Debian host is going to sleep and I can't awaken it without holdiing the power button down for some period. We have had some neighborhood power issues recently, and I have been manually powering down while away for a few short trips (no UPS yet, either, but my Windows box next to the Debian host [same power source] is solidly running). A search of the logs shows entries for power from various system sources on a daily basis (syslog)::, but I haven't seen anything about overheating or such. I know the internal motherboard thermal sensors work (don't ask), so I'm not worried about real overheating. Is there a way to definitely deactivate all OS-related power changes so the power button has only two functions (on/off)? Note: The systemd "/etc/systemd/sleep.conf" file has all entries commented out. Thanks for any ideas. -Tom

I'm pretty sure on my latest host the debian installer used /dev/sda (and partions 1 and 2) instead of a label or UUID. Of course I do want to add drives eventually, so maybe I do need to change to do that safely. Thanks. -Tom

When I get a multi-user system working with Raku as I want it to, I'll post it on this thread for your critique. On the original thread you kept wanting me to describe in detail my use case. The problem was (and still is) how to handle the following requirements: 1. Have root install the Raku executable for all users 2. Have the root user install modules for himself, but have normal users see and use them in their normal path. 3. Allow normal users to install their own modules which, for them only, would override the global version. This is somewhat analogous to Perl, but zef, the equivalebt Raku installer, is a bit pickier than cpanm about overrides. Best regards, -Tom P.S. Note Debian does have a Raku package, but most real users would rather use the latest and greatest. The language is under heavy development and there are real advantages for power users to stay current (a new version is normally release monthly). There is a painless Debian package system provided by our community similar to those provided by the PostgreSQL community. Do not think the syntax or user-space is changing due to the fast pace. Certain older things are deprecated and announced automatically when using them. Old code is usually compatible with new releases. A new release is always back-compatible until a new version is released. Raku is on its second version since its initial stable version release in December 2015. The third version, v6.e, is in the wings. And a user can always install an older release if all else fails.
setting paths for sudo (revisited)
For Greg: I'm trying to get my muscle memory to use "sudo -i" and "sudo -s" as you said to become root user for more work (thanks for the great explanation). One more question: when I need a one-liner as root, do I also use the '-i' or '-s' with sudo to get the desired path? Thanks, -Tom

Wow, another Garamond lover! I do, too, love it (and bought a copy of Adobe's version). I think Dr. Donald Knuth was the first person I may have heard mention it. How do you "set type" now? I have been "setting type" with Perl and raw PostScript (then converting it to PDF) for many years. I am now using Raku PDF modules to "set type" directly in PDF documents. All CLI products. -Tom

Roy, and many others, thank you for a voluminious set of helpful and timely responses. I need to assemble a spreadsheet to evaluate it all. I'm sure I have enough to make an informed decision.

Recommendations for a UPS?
I used to use UPS units from APC back when you could replace the battery. I haven't had an UPS (but always on a surge protecter) for awhile, but electricity (now FPL) is not as reliable in my new location and I need one. All the reviews I've seen on Amazon for smaller capacity UPSs for APC and Tripp Lite are not that great (I usually concentrate on the one- and two-star reviews). Any recommenndations from fellow Debian folks? Thanks. -Tom

Any way, I found the python script I prefer, so I'm heading in that direction. My visit to the fontforge IRC (#fontforge) was met quickly by a helpful person. The fontforge website, code, and documentation are daunting. I just wish they has used Perl instead of Python. I did think of symlinks, but I haven't spent much time on the script yet (I keep getting interrupted with "honey dos." -Tom P.S. I did read your signature--and enjoyed the visit (I have also visited several times over the years). I also used your blog on network manager when I was bringing up a couple of new hosts last--thanks! P.P.S. Do you know Bill and Carol Mantey?

I should have mentioned in OP the logs are in a dir under my own apache installation dir, and they are text files. I’ll try to get “logrotate” to take them over. Best regards, -Tom

Apache logs and systemd
I’ve been running httpd for many years, long before systemd came along. Somewhere in the various upgrades over the years I lost the old rotating logs. Now I would like to initiate the rotating logs again. Can I do that with systemd somehow? Thanks, -Tom

You can feel the difference Larry Wall and his many helpers released Perl 6 (now Raku) on Christmas Day, 2015. It is a much more modern language than Python, and it was designed as a "one-hundred year language." Check it out at https://Raku.org. -Tom
