Re: I need help with my var partition.

[Maureen L Thomas]

OK so I went looking on the net /debian/var to find out why it is 
running out of room.  All I could find is the directions to delete said 
files.  I will put them back, now.

Deleting /var/log etc is at best unhelpful.

I can't think of any procedure that would require deleting those 
directories. Perhaps someone was fooling with you?


Without knowing what else you have done or why, it's probably a good 
idea to recreate the directories


cd /var

mkdir log

mkdir tmp

Before you do a reboot, perhaps explain what else you have done and why?

First of all, please do back-up your *important* data.
Such as pictures, video clips, diary, some text docs, etc.

(Also i'm Debian user with Debian Bullseye under ThinkPad notebook)

Re: Need help to install gnucobol

[Jerry Mellon]

Hi,

I am new to Debian and I would like to install gnucobol. I see it is in 
Debian 10 but not 11. I tried to download the Debian 10 gnucobol, but I 
get a message that the package is broken. Could you tell me where else I 
might obtain a compatible cobol compiler?

I compiled gnu-cobol and have it working. I obtained:

gnucobol-3.1.2.tar.xz

tar axvf gnucobol-3.1.2.tar.xz
cd gnucobol-3.1.2
./configure
make

Probably there were errors which I fixed by installing things. See how
far you get.

Hi, Amine,

Did you run apt update before apt install ?
sudo apt-get update

This command downloads and builds a local cache of the list of available
packages.
When you use the apt install command, apt package manager searches
the cache to get the package and version information and then download
it from its repositories over the network. If the package is not in this cache,
your system won’t be able to install it.

Given these comments, I am not understanding why you are trying to
install from tarball when it appears to me that Tomcat is available in
the Debian repos (at least in Bookworm and Sid):

https://packages.debian.org/search?keywords=tomcat

It looks like 'tomcat10' is the package name you are looking for.

Try booting with Debian 11 Bullseye live images.
https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/11.6.0-live+nonfree/amd64/iso-hybrid/
If
all your hardware works with Bullseye then go with it. Debian testing is
nice but it can from time to time get hosed. Since you have been running
testing since Bullseye was in testing it should be good to go for you.

I have debian testing running on AMD Ryzen 7 4700U with Radeon Graphics
with 16 Gig's of RAM and I have had some shell crashes recently. The
background turns grey and everything freezes except the mouse. I am able to
switch to a command line terminal without issue. TOP and free -h both show
that I have lots of available resources and there isn't any one run away
process using all my resources.

I am also having a problem with KDE's instant messenger complaining that I
do not have kaccounts-integration installed. I tried reinstalling it and it
still reports that it is not installed. Trying to launch "Instant Messaging
Settings" caused the system shell to crash and appear to be locked up. The
mouse still moves just fine.

I would move to Bullseye but I need Firmware in Bookworm to run my Sound
and WiFi. I am not a fan of backports, I have never had a good experience
with it. Installing software with backports is no trouble but keeping them
up to date is an issue because it does not automatically want to install
newer versions even when the package was installed form backports.

Earlier you wrote "I've been using this laptop for the past 3 years
with the same setup with debian testing since its new", which means
that you should be able to run this machine with bullseye.

If you run testing, do full-upgrades, and expect full-upgrades are
going to fix things, then you might be better off sticking with
the stable distribution, assuming you were to go back to Debian.

Cheers,
David.

following the suggestion to try another OS i booted the computer with
ubuntu 22.4 live usb, i'm working with since yesterday with no issues. i
have enough memory so i installed some of the applications i use like
slack,zoom,terminator and more, i even installed intellij idea and worked
on my project for hours. zoom works with video ,slack works, there is no
freeze , the computer is up with ubuntu 22.4 for almost 24 hours and
everything looks ok.
So i guess there is no hardware problem.
So i don't know what to do, I'm thinking to reinstall debian but I'm not
sure the problem will disappear because it may be something with the kernel
of some package.

I tried SysRQ and there is no response when the computer freezes. i tried

and k and it worked. but when the computer freezes there is nothing, no
response.

lspci leads me to wonder if lspci is triggering a hardware flaw
somewhere on the PCI bus. And Zoom might do the same thing: I
conjecture that it looks for cameras on the PCI and USB busses.

Does it always freeze at the same point in the lspci listing? What
happens if you do a verbose listing? 'lspci -v'

Can you get a complete lspci listing using an older version of Linux,
or a live CD version (e.g. finnix)?

I would suggest:

- try to get more debugging info using netconsole[2] (needs wired connection)

laptop freezes randomly - please help!! dell xps 15 with debian testing

[Shalom Ben-Zvii Kazaz]

Hello,
Sorry for starting a new conversation, the previous one didn't help me and
I hope that now I have more details.
I don't have any idea how to approach that, its my workstation and the past
few days I just couldn't really work.
I'm also not experienced with this mailing list and a bit confused how to
reply here. I hope this time I will do it right.

In the past week my laptop freezes randomly, I can say it happens every 2-3
hours. but there are actions that consistently always cause a freeze, like
opening Zoom or executing lspci in Terminator.

Its a dell xps 15 7590, Intel® Core™ i9-9980HK × 16, 64.0 GiB memory, Mesa
Intel® UHD Graphics 630 (CFL GT2),
The laptop is attached to a dell docking station wd19 with an external
monitor and keyboard and external mouse.
It's running Debian GNU/Linux bookworm (debian testing) with Gnome.
I've been using this laptop for the past 3 years with the same setup with
debian testing since its new.
two month ago an official Dell technician replaced the keyboard and fans
and cooling board while still under Dell warranty.

The freeze started a few days ago after I did full-upgrade. Since then I
did full-upgrade again a few times hoping that it's a bug that was fixed
but it's still freezing.

I always have a few projects open in Jetbrains Intellij idea and rider. I
configure Intellij with 20GB memory, always a few browser windows open with
many tabs, usually brave and chromium. I always have a few windows and tabs
open in Terminator. and more.
The freeze always happens as a result of some UI action. examples are when
i tried to open settings, or some action in Intellij idea. It's completely
random and happens with other applications too.
there are actions that always cause a freeze, i tried that again and again
restarting the computer every time and it's always the same result, and
something suspicious with terminator:
trying to open the Zoom app always causes a freeze, I use zoom regularly
and there was never a problem until a few days ago.
trying to execute the command lspci in Terminator always causes a freeze,
everything else in terminator works. executing lspci in Gnome terminal
works, that looks to me very suspicious. I tried that at least 10 times to
make sure that it's not a coincidence and it's always the same, typing
lspci in Terminator and then Enter freezes the computer, but not in Gnome
terminal.

What I did:
As suggested to me here, I connected an ssh session with top and
journalctrl -f  from another computer and waited for a freeze. I have the
latest messages from both at the bottom of this message.

I started the computer with a gnome classic session, same thing, computer
freeze. started with xfce session, same thing.

I ran the Dell pre-boot performance test including a full memory test and
it passed OK.
I removed all the devices connected like external mouse and keyboard and
same thing.
I detached the laptop from the docking station and the computer freezes
when trying to open zoom or execute lspci in Terminator.

I hope someone can help in finding the cause of that freeze.

this is info i collected
This is journalctrl from another computer in ssh session just before the
computer freeze, the freeze was exactly at 16:39

WiFi Debugging Help

[Charles Curley]

In the course of helping (I hope) another user with a WiFi problem, I
stumbled across what could be a useful tool for such issues:

https://wireless.wiki.kernel.org/en/users

In particular, those with Intel WiFi adapters will find this page
useful: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

For other adapters, it might help to have the PCI or USB ID of the
adapter handy.

This might be useful information for the Debian manual.

I have used the following procedure to fix booting from a disk that
causes the system to drop to the grub shell instead of booting normally:

When in the grub shell, type ls, and you will see a list of the available
disks and partitions. You will see items like (hd0,gpt1) which would be
the first gpt partition on the first disk. Then you can list the files in that
partition using 'ls (hd0,gpt1)/'. You should then look for the partition with
the boot/grub/grub.cfg file, and then use the configfile command from
the grub shell to load the grub configuration on the disk from the broken
machine which should allow you to boot the Debian system that is on that
disk. For example, if the grub.cfg file is on (hd0,gpt1), then you do:

grub> configfile (hd0,gpt1)/boot/grub/grub.cfg

Hopefully you will see the normal grub menu giving you the option to
select on OS to boot, and hopefully you will be able to boot the Debian
that is on the disk from the broken machine.

If you can get the Debian system on the disk from the broken machine running,
then you will need to reinstall grub to update your grub so it can boot using 
the
disk from the broken machine without dropping to the grub shell. For example,
If you use efi, you will need to reinstall grub-efi-amd64-bin or maybe
grub-efi-amd64-bin-signed for secure boot, and after that it should boot the
disk from the broken machine without dropping to the grub shell.

Re: Help: disk swap

The second disk would need to be connected to the running linux in some
way either by a disk dock or a disk caddy such that the running linux
could find the second disk using lsblk and blkid.  Once located, parted -a
optimal /dev/xxx and then print to show the partition table then quit on
/dev/xxx could reveal boot partition information.  I have a disk caddy
here for sata disks which has its own power supply and that caddy also
boots external ssd drives once inserted correctly since the connectors for
sata and ssd are identical.

It would certainly be easier to help if that was the situation.

We have been told that both machines were running Debian 10. But a
problem is as yet we don't know if they have similar or different boot
systems. That lack of information makes it very difficult to give advice.

So trying to modify disk "A" to boot machine "B" could be tricky. But
perhaps trying to get disk "A" to boot machine "B" is an XY problem that
can be avoided, if maybe Tony only needs to recover some data off
disk "A" onto disk "B".

Given that Tony is not finding this easy, another approach that might
be easier would be to keep the backup machine "B" intact and working
and booting with its disk "B" connected as previously.
And then use something like this:
  https://www.newegg.com/sabrent-ec-dflt-dock/p/N82E16817366069
to connect disk "A" to machine "B".

And then the desired data can just be copied off it, and that might
meet all Tony's needs.

This method can also reveal evidence of what boot system is used by
both machines, and would permit modifying disk "A" if that turns out
to be necessary.

I find this kind of drive dock very useful for admin flexibility and
rescue tasks. I think they are a versatile and useful general purpose
tool for tinkering. So, a worthwhile investment, in my opinion.

You'd need to provide more information about both your computers and
how they boot in order to get better help. That would include whether
each one boots with EFI or the BIOS, and whether the disks are MBR
or GPT. It would help to know whether A's disk has a separate /boot
partition like B's does.

In the meantime, you could try the following commands from the Grub
Rescue prompt. It's not straightforward as only a subset of commands
will work. It's very likely to fail if the two computers boot in
different ways. All the disk and partition numbers below are just
examples: substitute according to what Grub finds present.

grub rescue> set pager=1

  in case you type a command that produces more than a page of output.

grub rescue> set

  will list the environment. The interesting ones are prefix and root,
  as these are the ones you might need to change.

grub rescue> ls

  should tell you what Grub calls your disk. It might look like:

  (hd0) (hd0,msdos4) (hd0,msdos3) (hd0,msdos2) (hd0,msdos1)

  or ditto with msdos→gpt. If you only see:

  (hd0)

  then you should see the partitions by typing:

grub rescue> ls (hd0)

  If you know the partition layout of the disk, and where
  /boot is, then you can type:

grub rescue> set prefix=(hd0,msdos3)/grub
grub rescue> set prefix=(hd0,msdos2)/boot/grub

  The first is where /boot is separate and on the 3rd partition,
  whereas the second is where boot is in the root filesystem on
  the 2nd.

  Similarly, you need to set the root partition by typing:

grub rescue> set root=(hd0,msdos2)

  You'll notice that that would be appropriate for the second example
  above, where /boot was in the root filesystem.

  Say you don't know the layout of your disk. Then you have to poke
  around with ls, using commands like:

grub rescue> ls (hd0,msdos1)

  which, for a root filesystem, should show bin dev etc lib and so on.

  Once the prefix is set, you should be able to get more of Grub
  loaded by typing these two lines:

grub rescue> insmod normal
grub rescue> normal

  I can't remember if the prompt changes, but you should have more
  commands available now.

  At a minimum you need, for a system where /boot is not separate,
  but in the root (and first) partition:

grub> insmod linux
grub> linux /boot/vmlinuz-… root=/dev/sda1 ro single
grub> initrd /boot/initrd.img-…
grub> boot

  Filename completion should word at …, and note that the kernel
  root parameter uses kernel notation, not Grub's. (Fortunately,
  both count partitions from 1 nowadays.)

  It's possible that you need to insmod more modules, so report
  at which step it fails.

Cheers,
David.

Although it does no harm, "defaults," is unnecessary and can be
omitted there.

Because it specifies defaults.

And defaults are values that are used when nothing is specified.

It can be omitted because "nofail" by itself is sufficient to establish
column 4, so that later values occur in columns 5 and 6.

"defaults" in /etc/fstab should only ever be used by itself, in column
number 4, when a non-default (ie not 0) value is required for one of
the following columns. Its function is to occupy an otherwise empty
column number 4, so that what follows it on the same line occurs
in column 5.

You might not be able to.  I once had a power supply fail
in such a way as to destroy the motherboard and the two
hard drives in the machine.  I lost about 180GB of stuff,
only some of which I was able to replace.  My backups are
_much_ better now.

Let's hope you're luckier than that.

I would look at the UEFI vs BIOS boot options in the "backup" server and
compare it to the "broken" server and make sure they are the same. Also
check for BIOS updates and such.

It could be as simple as striking the right key at POST. If you have two UEFI 
PCs
and the disks were installed in UEFI mode, you might be able to select the 
foreign
disk with a BBS key:

BBS Boot Keys

[*]ASRock   F11
[*]Asus F8
[*]Biostar  F9?
[*]Dell F12
[*]eCS  F10
[*]eMachinesF10
[*]EVGA F7
[*]Gigabyte F12
[*]HP   F9 or ESC or ESC,F9
[*]Lenovo   F12 or F8 or F10
[*]MSI  F11
[*]Toshiba  F12

If one PC was configured to use legacy mode while the other UEFI, you might need
to go into BIOS to enable the other mode.

There are all sorts of reasons possible for your predicament. David's reply 
covers
many ways to minimize or eliminate the inconvenience of a PC or disk failure, 
and
includes your providing information for helping us to help you.

One possible way to encounter your non-recognition situation is to add the other
disk rather than substituting. Swapping SATA cables between the two drives with
both installed at once might work around that issue.

The "name" Gene's reply refers to is called a volume label, easier for mere 
humans
to deal with than the UUIDs Grub uses by default, and referred to by Jude. Use
e2label or tune2fs to assign labels where they don't already exist on EXTn
filesystems. Volume labels are how I do all native Linux filesystem mounting and
booting, never UUIDs.

Have the running linux system on the machine.  Run lsblk to locate the

I don't know what the antipattern is, that openssh doesn't follow.

Perhaps I need to make it clear that:

. I have set a password for root.
. I can login as root at the console, using that password.
. I do not want to login as root by password from any other
  system, be it mine or anyone else's.
. I do not want to force, persuade, or hint that anyone else
  should follow my preferences.

I have. On all my systems, root can login as root, by key,
on any other of my systems. And the same for me as me. Other
users (which includes me) aren't set up to login by key or
password to the root account: they use su.
(Or avoid login with sudo.)

The recipe I posted for the OP doesn't mention or use keys,
or use the root account. The secondary script (unlock-…)
that I use to run the main one does use ssh, but is silent on
the authentication method.

Charles suggested that the OP just run things as root. As
I was posting a script that's really designed for remote
unlocking, I thought it helpful to point out that in an
unaltered Debian system, you wouldn't be able to login as
root. (I see no reason against basing answers on a vanilla
Debian stable system.)

I didn't read the OP's question as necessitating that sort of
configuration. Anyone who thinks to the contrary is free to
add their own reply.

Isn't that what I did: I spelled out the exact limitations
that I impose, with the actual lines from the sudoers file,
complete with their parameters and partial values, including
the fact that after quoting (or not) the password to log in,
they're not expected to quote it again just for sudo.

> What's not to like?

I don't know. I posted a script that does more than what the OP
wanted to achieve (which was to avoid using the root account),
and because it's a real script, I tried to add any information
that explained specifics that might not be immediately understood,
like:

. why it's in .profile,
. what /home/0 is,
. why it prints a line between unlocking and mounting,
. who unlock is,
. why unlocking a system remotely might be attractive,
. why lines were added to the sudoers file.

> What's missing?

Evidently, a discussion on becoming root.

And if you're following along closely, and ignore the likely
circumstances of my script being run, you might point out that
there's no obvious way for user unlock to unmount or lock /home.

Cheers,
David.

Sorry if I was unclear. The point I was trying to make is that
OpenSSH allows you to change the behaviour we are discussing
if you wish so. So it /doesn't/ follow that antipattern.

As to the other points? Well:

 0. if you want to be able to login directly as root, /and/
   with a password, change the server's /etc/sshd_config
 1. if you can be bothered to set up a key for root, use
   that (generally preferrable to 0.)
 1a. you can even limit what a private key owner is able to
   do: e.g. "only backup". So even if someone manages to
   steal your remote backup's private key, (s)he'll only
   able to trigger a backup
 2. if you don't like 0..1a, there's still sudo. You can
   fine-tune what commands (and what parameters go with
   those) each (local or remote) user is allowed to invoke,
   and even whether they're supposed to issue a password
   for that or they get it "password-less".

What's not to like? What's missing?

Well, Charles seemed to have difficulty with understanding my first
paragraph, which I wrote merely to explain that I assume a root
password has been set. It seems odd to get three follow-ups, all of
which centre on the consequences of the ssh configuration chosen
by the Debian developers for a bullseye installation.

When you write a script to unlock and mount a partition, you can
do it in two lines:

# udisksctl unlock --block-device /dev/foo
# mount /dev/bar /baz

but that's useless as it stands, and needs to be embedded into
your ecosystem to be useful, which is why I posted my script,
a real example.

But after two posts about background information on setuid shell
scripts, you now write "the worst antipattern is to misuse tech
to force people to follow some nonsensical rituals". Strong words.

Perhaps you could elaborate on which specific rituals you find
offensive. I can't work out whether you're criticising my script,
or the Debian developers for the way they're now choosing to
configure ssh, or the linux kernel developers for the ban on
setuid shell scripts.

Cheers,
David.

Most sshd configs either prevent root from logging in directly
or prevent root from logging in with a password (ssh key
required).

I assume you know all that you can set "PermitRootLogin yes" in
your /etc/ssh/sshd_config (the default is "prohibit-password",
which fits the behaviour you are describing).

It's not recommended, (for good reasons!), but hey, it's your box,
and you decide what you deem to be "secure enough". After all,
security is context-dependent, and the worst antipattern is to
misuse tech to force people to follow some nonsensical rituals
(it happens far too often, alas, but OpenSSH isn't that sort of
software).

So you can change that, if you wish so. What's your point?

This sequence will be familiar to a lot of people:

$ ssh acer -l root   ➀
root@acer's password: 
Permission denied, please try again.
root@acer's password:   ^C

130 $  /bin/su - ➁
Password: 
bullseye on /dev/sda5 toto05
# ssh acer
Linux acer 5. … …➂
 …  …
Last login: Tue May 10 …
acer # mv -i .ssh/authorized_keys .ssh/hide-authorized_keys  ➃
acer # 
logout
Connection to acer closed.
# ssh acer   ➄
root@acer's password: 
Permission denied, please try again.
root@acer's password:   ^C

130 # 

IOW, though logging in to root by password is ok at the console,
it's not ok when remote. ➀

However, when I'm already root ➁, logging in by key is ok because acer's
root has my public key and I can prove I have the private key. ➂

If acer's root doesn't have my public key ➃, then I still can't login
to acer with ssh because password is all that's left. ➄

I don't give root's public key to other users, where "other" includes me.

I presume that in some respect, your systems differ.

/etc/fstab could mount /home, except for the context:

So any complexity, outside the script itself, arises from:

unlock has a home directory that's not on /home (which is still locked),
unlock can run just one program, and with strictly limited arguments,
unlock doesn't have to authenticate to use that sudo command,
I'm lazy and would rather type unloac than ssh acer -l unlock,
and I'm lazy and would rather type wake-ac than walk 30 yards
and a flight of stairs, plus return, just to press a button.

David.

I think it implies some kind of encryption, requiring a key to mount.

It's certainly what's being suggested by /me/, as can be seen in my:

  sudo udisksctl unlock --block-device "$j"

but that's not how rhkramer (judging by the 12:40:25 response¹) and
I would take Charles' post as meaning, but rather:

  $ su -
  # cryptsetup luksOpen /dev/sd  && /bin/mount \
/dev/mapper/ 

presumably with the command wrapped, as now, in a script.

I do myself, using keys, but only local-root to remote-root. Having an
ordinary user use sudo means that one script suffices to unlock /home
both from a remote machine or at the console. Of course, it's a separate
ordinary user because of their non-/home home directory.

Simplification and generalisation are quite important to me, so as you
can see, the script will work unchanged on any of my hosts, and though
I mentioned unlock-acer, that function is one of several that are
created on the fly, in this case from:

  function unlock- { # unlock /home before logging in or transfers
  ping -c 1 -W 1  | grep 'bytes from' # wake it up first
  date && ssh -X  -l unlock
  }

(The ping seems to help those powerline devices that some hosts use.)

But you *can* typically sudo on the remote system, which is what is
actually being suggested here.  I think.

I may think about that some more, but it is a general aversion to being in 
root, or switching to root while I'm doing "ordinary" things (like accessing 
information on some mounted-on-demand LUKS partitions).

That complicates unlocking partitions remotely because, even if you
can log in as root, you normally can't log in remotely as root.

I use a special user called unlock, whose home directory is on
/var/local/, to unlock my /home partitions:

$ cat /var/local/home/unlock/.profile 
[[ $- = *i* ]] && printf '%s\n' "(This is $HOME/.profile 2022 March 02 on 
$HOSTNAME, $(sed -e 's/.* \([^ ]\+\) *$/\1/;q' /etc/apt/sources.list) on 
$(findmnt -n -o SOURCE,LABEL -M /))"
[ ! -f /home/0 ] && printf '\n%s\n\n' "/home is mounted already" && sleep 1 && 
exit 9
for j in /dev/disk/by-partlabel/*-Home; do
printf 'Unlocking %s\n' "$j"
sudo udisksctl unlock --block-device "$j"
done
printf 'Checking partition\n' # in case there's a pause
mount /home
sleep 1
if [ ! -f /home/0 ]; then
printf '%s\n' "/home is now mounted" && exit 0
else
printf '\n%s\n\n' "/home is NOT mounted" && sleep 1 && exit 99
fi
#
$ 

So after introducing itself (note: my sources.list is doctored),
it checks that /home is not already mounted (note: there's an
empty file called 0 in the /home directory on the rootfs), and
then unlocks any partition whose PARTLABEL ends with -Home.

It then mounts the one that matches the entry in fstab.

Here's how I call it remotely:

$ type unlock-acer 
unlock-acer is a function
unlock-acer () 
{ 
ping -c 1 -W 1 acer | grep 'bytes from';
date && ssh -X acer -l unlock
}
$ 

And, of course, that would normally follow a call to wake-acer
(assuming it's not a laptop):

$ type wake-acer 
wake-acer is a function
wake-acer () 
{ 
wakeonlan 22:44:66:88:aa:cc
}
$ 

If you're not in group sudo (I have a root password), you'd
require lines like these in /etc/sudoers.d/foo:

User_Alias  LOCKER = unlock
Host_Alias  MYHOSTS = …, acer, …
Cmnd_Alias  UNLOCKING = /usr/bin/udisksctl unlock --block-device 
/dev/disk/*/*
Cmnd_Alias  LOCKING = /usr/bin/udisksctl lock --block-device /dev/disk/*/*
Defaults:LOCKER !authenticate
LOCKER  MYHOSTS =   UNLOCKING, LOCKING

Note that all this is running on a home LAN. I would do things
differently in a more open environment.

As for setuid scripts, they haven't been allowed since I started using
Debian in Sept 1996, which was on Debian's first release, buzz, running
2.0 kernels. Allegedly there was a Perl method of doing it that I never
tried out. It was meant to create a Chinese wall between anything that
originated from outside and the rest of the program.

Cheers,
David.

Why the aversion to doing things as root? Why not just run your scripts

Ahh, the (an) obvious (finally ;-) alternate solution is to incorporate the 
luks and mount commands directly in the c helper program, as that at least 
avoids the confusion (to me) of having both a script and a c program for each 
partititon (and I could consider "parameterizing" the partitions).

E.g., in my (typical) c program, instead of 

   setuid( 0 );
   system( "" );

do 

   setuid( 0 );
   system( "/sbin/cryptsetup luksOpen /dev/sd  " );
   system( "/bin/mount /dev/mapper/ " );

I poked around a bit. NetBSD seems to honour it... but grudgingly. Here's
from their sh(1) man page [1]

   BUGS
  Setuid shell scripts should be avoided at all costs, as they are a
  significant security risk.

"At all costs": that's a tall order :-)

Dunno what the other BSDs say. As to the other Unices... which

TL;DR use sudo.

You must have had an outdated kernel version back then, I think.

The setuid bit has been ignored for scripts in Linux since like...
forever. If my memory doesn't fail me, it must have been around
kernel 2.x, perhaps 3.x, so around of before 2010.

I remember writing a setuid wrapper for a specific application
back with kernel 2.0.36, so it must already have been a topic
back then.

There are many places out there as to why -- my search engine
gave me this [1] one.

You can, of course, patch your kernel. You could write a setuid
wrapper (a small setuid C program written to call your script:
a good exercise in writing security sensitive stuff -- did I get
everything right? ;-)

Or you can use a setuid wrapper written for you (called sudo).
Even this one doesn't get everything right from the get-go.
I'd still recommend this latter options. The one I wrote Back
Then [TM] surely has more holes than sudo.

The Linux kernel does not honor the setuid bit on a script.  Any script.
Anything that's executed via a shebang, rather than an ELF header.

This is for security purposes, as there's some sort of race condition
or something.  I forget the exact details, but the point is, you can't
do this.  Find another solution.

Help with suid (bash)

[rhkramer]

Aside: even though this is not a Debian specific question, I often use debian-
user as my first resource in asking Linux questions.

Background: 8 years ago I wrote a set of scripts to help me mount and unmount 
LUKS encrypted partitions as needed and as myself () rather than as 
root. 

Aside: This was (and still is) under Debian Wheezy -- I know I should upgrade.  
I do have installations of Jessie and Buster on other computers and am getting 
ready to install Bullseye on another machine which might replace the Wheezy 
machine (if I can run TDE under Bullseye).  Getting these scripts working as 
intended (that is, using suid) is part of my effort to do that.

Problem: I tried to use suid to allow the scripts to be run by me, but with 
the permissions of root  but I could not get that to work.  

Aside: I do run those scripts with the aid of a (compiled) c helper program 
that switches to root and then runs the appropriate script (setuid( 0 ) and 
then system( "" ). 

The script to mount a partition looks like this (comments deleted, and some 
things shown "generically" for privacy / security):

#!/bin/bash 
/sbin/cryptsetup luksOpen /dev/sd  && /bin/mount 
/dev/mapper/ 

The ownership and permissions that I tried to use (I tried some variations, 
and I have different permissions at the moment) were:

-rwsr-xr-x 1 root  1412 Aug 31  2014 


(I should remove the read and execute permission from all, but that is what I 
had at that time.)

Why can't I run that successfully as myself (), and what could I do 
to make it run?

When I invoke the script with those permissions, including suid, I get a 
response like:

$ 
WARNING!!! Possibly insecure memory. Are you root?
Cannot open device /dev/sd for read-only access.
$

To clarify: when I run these scripts with the aid of the c helper program, the 
scripts work as intended and I get no error messages.

Thanks for any input!

It seems to be more or less consent that you are not advised to run
Debian Testing on a productive system, one of the reasons is security
support. Is this system so new that it requires a kernel from testing?
bullseye-backports has kernel 5.16.12, the  kernel in testing is also a
5.16.x release.
It will probably not take too much time until 5.17.x or 5.18.x will
appear in bullseye-backports.

Exactly as Christian said.  Will like to learn about sound card 
configuration in general as well, so any suggestion is appreciated.

Thanks, and no worries.  The reason I haven't tried testing is that this 
is a semi-production system and I'd like the base system to be stable. 
Also I've seen some success story regarding this type of sound card on 
other Linux distributions with a sufficiently recent kernel (5.15-ish), 
so I'd like to at least try to make it work which will be a learning 
process.  In the worst case I may just wait for bookworm to become 
stable next year :)

Help settings up sound card on Debian stable

[manphiz]

Hi,

I have been trying to set up a Minisforum HX90[1] with Debian stable 
with backports.  Most of the stuff works out of the box except sound, 
bluetooth, and Wi-Fi.  I'll focus on the sound card issue here and use a 
new thread for the latter 2 items (which are related to the same 
MediaTek module.)


I've enabled backports repo and installed the latest backport kernel. 
It looks like the system can detect the device according to inxi output:


```
$ inxi -SMA

```

but note this line: "Device-2: AMD Raven/Raven2/FireFlight/Renoir Audio 
Processor driver: N/A" which seems to suggest that the driver is not 
available.  I tried to list devices using "aplay -l" but got no sound 
card available:


```
$ aplay -l
aplay: device_list:274: no soundcards found...
```

PulseAudio also reports only the dummy sink is available:

```

+1.  Get yourself a big USB HDD.  Learn how to take and restore a raw 
image of the SSD.  Take images on a regular basis (I do this monthly) 
and as needed (such as after a fresh install, before major version 
upgrades, and before decommissioning).  This is in addition to regular 
data backups (e.g. daily).

Looks like sda1 and sda2 are missing from the partition table.

If it's just that then putting that back but changing nothing else is
all that is needed.

I'd use fdisk to do it, but other tools might be easier/less error
prone.


But making a disk level backup first is strongly recommended! It's
really easy to make things worse.

It's not obvious to me why there is a gap between the end of the HFS
partition and the start of sda3. That might be expected or might mean
the sector numbers aren't quite right...

Tim.

Dank. Ik heb `apt-listbugs` uitgeprobeerd.

En op een andere plek leerde ik van `how-can-i-help` ( package naam is
ook `how-can-i-help` ) Dat is het programma wat ik zocht.

Hoi,

Er is een programma dat
- lijst genereerd welke packages je ge-installeerd hebt
- opzoekt welke bugs er van openstaan
- zo laat zien hoe te helpen


Nu ben ik de naam kwijt van dat programma.
Vandaar de vraag: Hoe heet het?

There is also a package "hello" which is intended to show how to package
things. So getting its source and looking around might be helpful, too.

Re: Packaging help: users and directories

[Gavin Henry]

I was given this advice from Arthur, a Debian developer, but I can't find
some of the finer details I'm looking for:

---
I recommend looking at https://wiki.debian.org/UpstreamGuide to some
pointers about how to make it easy to ensure your software can be
easily packaged in Debian.

If you're looking to create a deb package that is ready to be included
in Debian it is best to have your debian/ directory on a separate
branch. I recommend using git-buildpackage, see
https://wiki.debian.org/PackagingWithGit (this is what most
collaboratively maintained packages use now).

For information on how to create Debian packages see
https://www.debian.org/doc/manuals/developers-reference/ (particularly
chapters 5 and 6). If you want to look at more of the background there
is the policy document, see https://www.debian.org/doc/debian-policy/

There are a lot of tools for efficiently building Debian packages. If
you want to test your builds in a more controlled environment you
should probably use pbuilder (of cowbuilder) because those use a clean
chroot to build your packages to ensure you have the correct
dependencies specified.

Hope this helps

Packaging help: users and directories

[Gavin Henry]

Hi all,

Where are some good examples to read about adding a user and group, a
systemd service file, a /etc/default file and creating a
/var/lib/sentrypeer directory to hold an sqlite db file?

Just look at official packages? I've read

This is for:

https://github.com/SentryPeer/SentryPeer

and I've started here:

https://github.com/SentryPeer/SentryPeer/tree/debian-packaging/debian

Thanks for reading,

Most probably it is the stupidity of developers of course, especially if you
are on a new Gnome or KDE or derivative desktop.
Guys did not get it that they are testing for free.

But I admit there might be a chance to be hardware failure ... around 1%.
Few days ago the notebook stopped seeing the monitor. It turned out it is
the HDMI cable or the KVM inbetween - I need another cable to test ... but
luckily I have a PC store and can borrow one from there :D

I hope you have a sense of humor.

If this is on a laptop, for example, the solution could be as simple as

Are you using the unofficial non-free including firmware .iso to install 
from?

I'd suggest starting there:

https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/11.1.0+nonfree/amd64/iso-cd/firmware-11.1.0-amd64-netinst.iso

If you can install via Ethernet before using the wireless interface, I would
suggest that you do so.

I would also suggest installing the network manager package to configure the 
network interface. I find that nmtui is very useful.

Unless you absolutely postitively have to use buster at this point: if you
have it working under Bullseye - Debian 11 - use bullseye on this system.

This is an _old_ adapter 2013-2015, I think? and may not be as capable 
as newer hardware, but in this case I think there is soemthing else?

If you plug it into a bullseye machine and do the same, what do you see?

In any event, use the most up to date software that works.

Hi Steven,

Any particular reason to be using Sid? 

Where did you source your download from?

It sounds like a kernel/audio subsystem interaction problem but we'd need 
more details, I think.

Bug report help

I am having audio problems in Debian GNU/Linux bookworm/sid running on a
Raspberry Pi 4.
Kernel: Linux 5.15.0-1-arm64

I don't know that it is an issue with a package unless it is a firmware
package.

Some of the audio devices cause applications to freeze or will play at a
slower than normal speed. The Default (pulseaudio) device usually works.
ALSA devices are more likely to fail.

Often, after a reboot, pulseaudio will not start. I have to keep rebooting
until it works.

Hello

Thanks for your question. These lists are rather more in English. You
would be better to turn to debian-user-french for an answer in French

www.debian.org and wiki.debian.org also exist: it's quite possible that
one of these two [resources] can give you further support

WSL2 - effectively a layer that sits on Hyper-V shim and can talk to 
Windows subsystems. Allows you to run Debian as a VM, effectively.

Debian WSL2 bundle is maintained by a Debian developer.

Since your knowledge of Linux admittedly is severely lacking, I would
recommend thoroughly researching Linux, in general, and Debian, in
particularly, BEFORE attempting any install. And the first attempt be
on a system you don't mind trashing.

And always keep in mind: Linux is NOT Windows.  So never assume that
the way you did it on Windows will work on Linux.

Welcome to the neighborhood.

You processor has hardware support for virtualization:

Intel® Virtualization Technology (VT-x) ‡ Yes
Intel® Virtualization Technology for Directed I/O (VT-d) ‡ Yes
Intel® VT-x with Extended Page Tables (EPT) ‡ Yes


I recommend that you install Oracle VirtualBox, create a virtual machine 
(VM), and install Debian GNU/Linux into the VM:

I think the o.p. may have got debian linux confused with debian lynx that
makes more sense over here.  Many Linux distros have code words for each
major version of their distributions.  The current stable code word for
debian is bullseye.  I've been installing debian since sarge and remember
no lynx code word attached to any debian version.

How big is the hard drive, and how much space is currently occupied?

I rather guess that "Debian GNU/Lynx, The Unyversl operating system"
is meant. ;-)


Have a nice day :)
