At this point (with firewalls temporarily off) I was able to ssh to and from host and VM guest using their respective IP addresses. After adding a static route on my wireless router: 192.168.200.0/24 via 192.168.1.100 (to paraphrase the web form) I installed apache2 on the VM guest and was able to access http://192.168.200.151 from my phone over wifi, and websites on the host from the VM guest. Firewalld actived on host with ssh and https services allowed - ssh and web browsing worked as before. No nf/iptables jiggery-pokery, but static route on router required. Perhaps not the most efficient solution, but I try to avoid too many firewall rules because they make my head spin :) Don't think I've omitted any steps. Does that help? Best wishes, Gareth

Ah, I hadn't seen Geert's reply, which I think is closer to the mark :) This gives a routing-based approach: https://www.linux-kvm.org/page/Networking This creates an isolated network between host and guest, which without routing presumably is additional to the default network, and the (Ubuntu-based) netplan stuff needs substituting with /e/n/i adjustments: https://www.nodinrogers.com/post/2022-01-06-enabling-kvm-host-to-vm-communcation/ All of which I have yet to test but have been meaning to look into this again.

Hi Stephen, That might suggest NAT is still operative for the VM. Did you do the "optional" part of the tutorial in your link too, re KVM network config? What is the output of # nmcli con show # nmcli device # virsh net-list --all # virsh net-dumpxml yourNetworkName I don't have a network cable to hand to test this at the moment (wifi NIC bridging is complex if possible with KVM [1] and apples and oranges and all that) but will do later if your problem is not solved. I think the presence of enp2s0 in /e/n/i (which your attachment seems to be) prevents NM from managing it, but if I'm wrong about that, could it be getting an address (static or otherwise) from NM?

With an Alpine client (and no "tools") I get less than optimal scaling from virt-manager - some black space at the horizontal edges, but there is a scaling of sorts going on, just not entirely using the available window space. Are you using the stock version of virt-manager? $ apt policy virt-manager virt-manager: Installed: 1:4.1.0-2

The only Linux VM I have in virt-manager used the spice display manager by default.

Is Bookworm the VM client too? With GUI? Does this happen for all clients, just one, or one type? Off the top of my head, I think the scale always option may disappear if the guest display doesn't support it - I seem to recall VirtualBox Guest Additions being required for this functionality for some guests in VirtualBox (which I acknowledge you are not using, I'm just saying...) so I don't think it's "straightforward" functionality

I hadn't twigged that "status tray" was a separate thing to "notification plugin" in XFCE (hence my earlier nomenclature) though on inspection, there it is indeed!

Hi David, Starting from Mate DE only and some old (bookworm) XFCE config files, if I: $ sudo apt install task-xfce-desktop then log out and into XFCE, I get an XFCE desktop with wallpaper, desktop icons, panel, main menu, launchers, window buttons, notification area. Then I: $ mv ~/.config/xfce4 ~/.config/xfce4.old then logout and into XFCE again, I get wallpaper, desktop icons, panel, main menu, window buttons, notification area, but only non-functional launcher placeholder icons. $ diff ~/.config/xfce4 ~/.config/xfce4.old Common subdirectories: /home/user/.config/xfce4/desktop and /home/user/.config/xfce4.old/desktop Only in /home/user/.config/xfce4.old: panel } Only in /home/user/.config/xfce4.old: src } <-- these are subdirectories Only in /home/user/.config/xfce4.old: terminal} Common subdirectories: /home/user/.config/xfce4/xfconf and /home/user/.config/xfce4.old/xfconf Common subdirectories: /home/user/.config/xfce4/xfwm4 and /home/user/.config/xfce4.old/xfwm4 $ (though there probably wasn't much there to start with) I'm not sure what would cause this difference in behaviour (though wonder if this might suggest more amiss with your XFCE installation) and I will watch this thread with interest. Also I just "rediscovered" that reinstalling task-xfce-desktop doesn't reinstall those packages which it brings in in the first place, though I'm sure you knew that :) Sorry I couldn't be of more help.

There is apparently a long history of nm-applet/XFCE panel-related issues (and not many great answers), as evidenced by such as https://bbs.archlinux.org/viewtopic.php?id=161998 https://forum.xfce.org/viewtopic.php?id=6105 https://superuser.com/questions/900490/networkmanager-icon-on-notification-area-is-not-present If you get ps output like this directly after a reboot: >>>>> $ ps aux | grep nm-applet >>>>> dpchrist1518 0.1 0.2 426500 35380 ?Sl 16:06 0:00 >>>>> nm-applet then I don't think the issue is with the starting/running of nm-applet itself, but rather some issue with the notification plugin, which I'm not sure how to begin troubleshooting. I reluctantly abandoned XFCE partly due to panel instability some time ago. The advice in the final link to rm -rf ~/.config/xfce* might be a bit extreme, but I might try renaming it to force a rebuild on next login, and possibly reinstall task-xfce-desktop (or selected packages) Would be interesting to hear from anyone with XFCE panel troubleshooting experience.

Hi Mick,
With the qualification that it's been years since I've done anything much with
Perl...
$ apt search perl-tk
perl-tk/stable,now 1:804.036-1+b2 amd64 [installed,automatic]
Perl module providing the Tk graphics library
$ apt search tkpng
tkpng/stable 0.9-3+b1 amd64
PNG photo image support to Tcl/Tk<--- isn't this "not for perl"?
I couldn't find any reference to "tkpng" in
https://metacpan.org/dist/Tk
but there is:
Tk::PNG - PNG loader for Tk::Photo
(in the table there is no hyphen but wider gap)
Someone had a similar problem with Strawberry Perl on Windows. Does this help?

This excludes it appearing in any of the /dev/disk/by-*/ identifiers, which I have also checked separately just in case. I git cloned grub to see if I could make sense of how grub.cfg is generated. $ git clone https://git.savannah.gnu.org/git/grub.git According to NEWS for v1.97: > * update-grub is replaced by grub-mkconfig So after making some sense of grub-mkconfig.in, it turns out the 16-digit hex number is returned by # grub-probe --device /dev/sda3 --target=fs_uuid 9cbef743dfafd874 Given that the above command fails with --device /dev/sda4 (which is the running system's /), gpt3 appears to be sda3, ie. the boot partition, so --set=root in the grub.cfg search line presumably relates to the root of /boot. I'm still curious as to why it doesn't seem to appear anywhere else, how it was applied, and what exactly it applies to - a filesystem? This is not aiui the usual form of a UUID either. grub-probe.in or grub-install.c might hold answers. I will reply again if I discover anything informative. Thanks, Gareth
/boot/grub/grub.cfg hex number reference
Does anyone know what the 16-digit hex number (truncated below to 9cbe...)
refers to in /boot/grub/grub.cfg, where it makes several appearances?
# grep 9cbe -A2 -B2 /boot/grub/grub.cfg
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt3
--hint-efi=hd0,gpt3 --hint-baremetal=ahci0,gpt3 9cbe... <---
else
search --no-floppy --fs-uuid --set=root 9cbe... <---
fi
That suggests perhaps something to do with an FS UUID, but it doesn't seem to
appear in the output of any of
# blkid
# lsblk -o MODEL,NAME,LABEL,WWN,UUID,SERIAL,PTUUID,PARTUUID
# zfs get all bpool|grep 9cbe
# zfs get all rpool|grep 9cbe
# zpool get all bpool|grep 9cbe
# zpool get all rpool|grep 9cbe
The previous hex number appeared in a grub error ("no such device: ")
after a failed update-grub, either after recreating the boot partition or the
ZFS boot pool on it, or both. This caused a delay during boot of approx 10s
while being invited to "press any key to continue" immediately.
After running update-grub, the hex number was replaced with another in
grub.cfg, and the error message and boot delay disappeared.
For info:
There is currently a bug in grub whereby if a ZFS boot pool is snapshotted at
the top level, the compression type "inherit" can result in the grub error
"compression algorithm inherit not supported", and a broken boot process, which
is what I was sorting out when I noticed this.
https://github.com/openzfs/zfs/issues/13873
https://savannah.gnu.org/bugs/index.php?64297
According to some comments on github, it doesn't seem to be definitively fixed
in grub 2.12, not that I have tried.
Snapshotting boot pool datasets is said to be OK.
Thanks,
Gareth

You want the 'history -r' command, "explained" by `help history`. After you end the script, you're back in the bash instance you ran 'script' from. When you ended the script & therefore the bash being run in that script, that bash wrote its commands to ~/.bash_history; but the bash you're running, which is the one you ran script from, hasn't read that ~/.bash_history. Running 'history -r' will cause it to do so. BTW I've got some kind of email configuration problem that usually prevents me from posting to debian-user, even though I can usually email individual users. Gareth, if you get this, and it's the correct solution to your original problem, perhaps you could post it to the list; this email is CCd to debian-user, but I expect the CC to bounce.

Hi Max, Thanks for links and suggestions. It seemed to me initially (as I should perhaps have stated) that man script was suggesting that csh was a component or depedency (of script), which seemed to be contradicted by it not being installed. On reflection, possibly, it's just a way of doing things in script. The reference in man script now seems to imply the latter. The fact that script scripts bash on my machine made me not think about the fact that it probably scripts whatever shell it's running from, and was doubtless written with one in mind/as inspiration - csh might make a certain sense in that respect. script runs in bash if run from csh run from bash, but I suppose csh in that chain of shells isn't a proper [do I mean login?] shell. (Got that? :p) The function of the "a" option in History Substitution in man csh seems different in the bash version.(under "Word Designators" in man bash/gnu online manual) It'll be interesting to test when I can make sense of it :p Anyway, my orginal question has been answered. Thanks all. Gareth

The update in bookworm-backports to 2.2.2-3 allegedly fixes this issue.
I have installed it and at least rebooted :)
I have had ZFS on root since Buster, and have upgraded to each new stable
release since then.
I had wondered recently if the Debian wiki's recommendation [1] of installing
from "stable-backports", and the statement that
"Upstream stable patches will be tracked and compatibility is always maintained"
was to suggest use of the actual "stable-backports" repo, and that the
compatibility guarantee meant that they cater for any potential ZFS issues
arising for non-upgraded systems after new release time. On closer inspection,
the line the wiki provides to add this to sources.list actually adds the
codename-backports repo (currently "bookworm-backports"). "stable-backports"
also appears to be an alias that apt understands as referring to
{codename}-backports for whatever current stable is, and use of the actual
"stable-backports" repo is not recommended or implied.
Is the Debian wiki advice re installing ZFS from backports applicable in all
circumstances? What would be the suggested approach for installing with ZFS on
root or re-pointing apt at backports for ZFS immediately after [upgrading to] a
new stable release? Do backports even exist at that point? If so, after a
release upgrade, can you install the same version of eg. zfs-dkms from
backports as a sort of special case for the purposes of changing the repo? Or
do you just have to watch and wait for new ZFS backports?
OpenZFS instructions [2] for root on ZFS suggest using bookworm not
bookworm-backports, so I wondered if an initial lack of backports might be the
reason.
Thanks,
Gareth

Re: The bug (was: Is it safe to install Bookworm on a new machine now?)
Can anyone please explain: 1. Why upgrades of stable into a potentially seriously compromised state were allowed to continue, twice, rather than pulling the upgrades? or... 2. Why the best temporary solution isn't to revert the kernel to the last known good version so upgrades-other-than-kernel can continue? There may be some versioning jiggery-pokery needed, but doesn't the +deb12xxx (or other) naming convention take care of that? I'm sure I've seen packages previously with names like foo-1.3-really-1.2 This really doesn't seem to have been handled well from an official mitigation/communication pov. There only seems to have been a debian-announce announcement re 12.3 issues. I'm inclined to think there must be reasons why things that seem obvious have not been done, and keen to understand why, if so. Do 1 or 2 above involve disproportionate effort? Were there backwards-incompatible changes to other things (such as filesystems) in the latest kernel(s), so reversion = breakage for some upgraded systems unaffected by recent issues? Thanks, Gareth

Hi Tom,
I find Atril and Okular to be capable viewers, both with CLI options detailed
in
$ man {atril|okular}
I sometimes find Atril less than snappy in displaying (and repainting)
graphic-intensive PDFs.
> A bonus would be one with documented CLI use with CUPS printers.
What do you want to do that can't be done with (for example)
$ lp file.pdf
?
I'm not sure what you mean by "CLI use with CUPS printers".
$ man evince
includes
"Print preview options [...]
--print-settings %s %f
This sends the full path of the PDF file, f, and the settings of
the print dialog, s, to evince."
If that was what you meant, I note there seems to be no equivalent documented
for atril or okular, but I don't quite understand how "%s" is to be
identified/specified etc. Some other application's print dialog?
Perhaps you or other(s) can enlighten me.
Thanks,
Gareth

Hi David, In general, outside of certain relatively niche use cases, I believe software raid is to be preferred due to comparable performance and lack of future hardware compatibility/availability issues. See for example (if with some contradictions) https://www.techtarget.com/searchstorage/tip/Key-differences-in-software-RAID-vs-hardware-RAID Debian supports software raid, in the form of MDRAID. I seemm to recall this is usually combined with LVM. OpenZFS may be of interest, possibly root on ZFS too. https://en.m.wikipedia.org/wiki/OpenZFS https://openzfs.org/wiki/System_Administration https://openzfs.github.io/openzfs-docs/Getting%20Started/Debian/index.html There doesn't seem to be documentation for root on zfs for bookworm yet. I imagine the bullseye instructions, suitably adapted for repositories etc, might suffice, but I upgraded a root on ZFS installation from Buster to Bullseye to Bookworm (following the release notes in each case) so haven't tried to install from scratch in years. You will need to turn hardware raid off in either case (MDRAID or ZFS) If you have actual raid controller cards, that may not be possible iiuc - I'm sure someone (maybe even me) could advise if you provide details of raid hardware if relevant.

Clearing this file solved the problem." 2. "I noticed that when I change UsePAM yes to UsePAM no then this issue is resolved." There may be security (or other) issues with (2). To avoid the risk of locking yourself out of VPS I would Copy /etc/ssh/sshd_config elsewhere Amend the copy to include UsePAM no $ sudo /var/sbin/sshd -f /path/to/sshd_config_copy -ddd -p1235 (NB use new port number if previous command still running) then see if you can ssh to it. If the issue is not solved by either of the above, please give any sshd debug output that seems relevant for a few lines before/after the wait. To view the systemd journal, see man journalctl You may however like to install rsyslog to get /var/log/syslog back. Not sure if it's retro-active though. HTH Gareth

Stephen said this happened "when [he] logged in." Stephen, assuming you actually logged in before the issue occurred, did you log in to a login/display manager such as LightDM or did you log in to a console/CLI prompt and subsequently run startx, whereupon the issue occurred? If the former, either X or Wayland is running at the point of "login screen", isn't it? At some "standard" (high-ish, working) resolution?

My previous message suggested xrandr -q but this https://unix.stackexchange.com/questions/651209/how-change-monitors-from-terminal-xrandr-cant-open-display suggests xrandr expects to run from within a running X session.

Buster / Google Remote Desktop
It seems Google Remote Desktop, a Chrome extension, does not work properly with Buster + Mate. I haven't tried with Bullseye, which is not an option in the environment concerned due to CUPS bugs, but in Buster there is about 5 seconds of remote-mouse-movement then no more. Does anyone know of a way to fix this, or any other approach that might work through a mobile broadband router (at the 'controlled' end) where there is no option to fwd ports? Thanks, Gareth

The only reference to this error I could find was this https://bbs.archlinux.org/viewtopic.php?id=168485 which (a long time ago) seems to have been resolved by using matching cups versions. I find my Brother MFC-L2740DW is only detected on Bullseye if both devices use the same wifi band (the printer supports only 2.4GHz). I'm sure this was never a thing in Buster, but I may have switched bands at some point and forgotten about having done that. I imagine it could conceivably be due to a dodgy ISP router firmware update too.

Brandeis > Genes Web page <http://geneslinuxbox.net:6309/> Hi Gene, Not sure if CUPS debugging may be helpful, see eg. https://sysadminera.com/2020/09/10/linux-how-to-enable-and-capture-cups-debugging-logs/ But first, I seem to recall you removed avahi and cups-browsed from Bullseye machines. Is that correct? Do the Buster machines have either or both of those installed? What are the exact models of the Brother printers "missing" from Bullseye systems? Do other printers appear on Bullseye systems? Thanks, Gareth

Sorry, the point I was getting at didn't quite emerge!
I meant the fact that there are blank lines in the example
https://www.rfc-editor.org/rfc/rfc2049#page-15
before each boundary, as well as after all of the part field headers, it being
a conformance example, initially suggested requirement to me. But I now
realise that the example's blank lines before the part boundaries are there for
readability purposes, and form part of the sections including the text
preceding them. So the example leaves that at least for the reader to
interpret correctly.
I discovered last night that the BNF for the formal definitions, which you have
to string together to generate a blank line from concatenating CRLFs, appears
in RFC 2046. This isn't named or linked to in 2049's Abstract, as the other
docs in the latest MIME "set" are. I was skimming a bit and didn't see the
other references to it.

That quote was from 1521:

>> " 7.2 ... Each part ..."
- whereas afaics, 2049 only offers the note in Appendix A, from which the
necessity for a blank line following part headers can be deduced, but you have
to think about it, and know that it needs to be thought about. I thought the
idea of RFCs was at least partly to explain thing

Hi David,
It doesn't, save for one mention in the appendix, and that was sort of my
point...

Well... I meant "suggests" literally, because...
At the time of writing the message you refer to above, I had taken the Appendix
A example in RFC2049 ("[MIME] ... Conformance criteria and examples") to be
prescriptive by example (a "conformance example"!), given blank line
requirements are less than definitively spelt out there.
RFC1521, obsoleted by 2049, includes:
" 7.2 ... Each part
starts with an encapsulation boundary, and then contains a body part
consisting of header area, *a blank line*, and a body area ...
NO header fields are actually required in body parts. A body part that
starts with a blank line, therefore, is allowed ..."
https://www.rfc-editor.org/rfc/rfc1521
but this text does not appear in RFC2049, where the notion is merely implied in
a bracketed note in an example in an appendix, which also contains the only
appearance of "blank".
"Appendx A -- A Complex Multipart Example
[...]
MIME-Version: 1.0

Subject: A multipart example

This is the preamble area of a multipart message.
Mail readers that understand multipart format
should ignore this preamble.
If you are reading this text, you might want to
consider changing to a mail reader that understands
how to properly display multipart messages.

--unique-boundary-1
Content-type: text/enriched
This is enriched.
as defined in RFC 1896"
https://www.rfc-editor.org/rfc/rfc2049.html#page-15
There are blank lines between part header fields and content - but this
requirement is implied rather than specified in terms, as it is in 1521.
There are blank lines between content and following boundaries - this may be
for readability purposes, but at the time, I thought this suggestive of
requirement.
I read somewhere else (which I now can't find) that a boundary must be preceded
by a CRLF, which is considered part of the boundary - but not necessarily a
blank line.
Best wishes,
Gareth

I wonder if there may be some anomaly in the true source which doesn't make it through "view source", the clipboard, you sending the paste, the mailing list servers, and other people's mail clients.

I think it would be easier to clear the cache and other data (possibly
including history if you wish) automatically when the browsers close. There
are usually settings available to do that.
See below.

If you mean an actual bookmark, clearing the history will not remove this.
For Firefox:
Settings > Privacy and Security
- Delete cookies and site data when Firefox is closed
- History
-- Clear history when Firefox closes [Settings...]
There are options for what to clear if you click the "settings" button, such as
- browsing history
- cookies
- cache
So there seem to be two ways to clear cookies and site data when closing
Firefox, but I'm not sure if the options under History > Settings include all
the "site data" removed by the other setting.

I had assumed no blank line preceding a boundary was required as Tb still processes the boundary without one, but https://www.rfc-editor.org/rfc/rfc2049.html#page-15 suggests this is in fact a requirement. So perhaps a bug. G

If you haven't already tried View > Message Body As > Original HTML when viewing the "empty" plaintext version of the message, I think it should produce the same result as I got from saving the source to a separate file.

It's sometimes necessary to "base64" messages from web-based wrappers to avoid bugs in header/message formatting. I've had this experience with PHPMailer. But the failure of "re-entrance" is because one of the blank lines in the text/plain multipart section of the raw message is interpreted as content, and Tb is displaying it (and more). If I click on the "blank" plaintext version's window in the (would-be) message display area, to give it focus, then select all copy paste into a text editor ...two line breaks are pasted. I'm not convinced *two* line breaks should be pasted, but there we are. I use MATE DE and the Caja file manager. Tb is my default email client. Evolution offers to import the message from mbox format when I: - right-click gene.eml - Open with... > other application > Evolution Mail and Calendar ...and it shows a preview of the HTML version immediately. I'm not sure this is a Tb bug, just perhaps a "purist" way of doing things which avoids "knowing what the user really wants", which (more generally) seems liable to unintended consequences. > Or, is there some option I can set that will enable its display. Much as I seem to recall one, I can't find a way to make Tb display HTML by default if it exists. This rather old forum post suggests that's the way things are, or at least were: "'View' > 'Message Body As' > 'Original HTML' is the setting to display received emails in HTML format" https://support.mozilla.org/en-US/questions/1113744 The reply there refers to a Tb extension "Allow HTML Temp" https://addons.thunderbird.net/en-GB/thunderbird/addon/allow-html-temp/?src=cb-dl-mostpopular?src=cb-dl-mostpopular but from the description, I'm not sure if this does quite what you want.
