Difference between LUKS drives with cryptsetup and Disks?

[Joerg Desch]

I've created a LUKS partition which I mount on demand. This partition was 
created using cryptsetup. While mounting the partition, GNOME asks me 
first for the passphrase and than for the "admin" password.

A while ago, I've created a LUKS partition on an USB thumb drive using 
GNOME Disks. In this case, mounting requires only the passphrase. And 
that doesn't depend on the used computer!

What is the difference? Can I change the behavior of my older LUKS 
partition too?

Most probably this is a permissions problem.  Mount the partition
which you encrypted with cryptsetup and do a

ls -ld /path/to/mountpoint

there you will see the owner (probably root) and the permissions
set for this mount point.

If this is the case you may change the owner like this:

sudo chown -R youruserid:youruserid  /path/to/mountpoint

GNOME uses udisks2 to manage devices.  udisks2 treats removable devices
(can mount as regular user) and system devices (can only mount as admin)
differently.

One can find the actions udisks2 uses PolicyKit for in
/usr/share/polkit-1/actions/org.freedesktop.udisks2.policy: the
interesting ones probably are:

  org.freedesktop.udisks2.filesystem-mount
  org.freedesktop.udisks2.filesystem-mount-system
  org.freedesktop.udisks2.filesystem-fstab

  org.freedesktop.udisks2.encrypted-unlock
  org.freedesktop.udisks2.encrypted-unlock-system
  org.freedesktop.udisks2.encrypted-unlock-crypttab

The default permissions allow the active user to use 'filesystem-mount'
(that is mount removable devices) and 'encrypted-unlock' (unlock
removable devices).  The other actions are only allowed for
administrators with a password prompt (`auth_admin` or
`auth_admin_keep`).

As you only want to manage a single partition, I would try to use the
'filesystem-fstab' and 'encrypted-unlock-crypttab' actions which should
only apply to specific devices instead of the '*-system' actions: add
the 'x-udisks-auth' option to the /etc/fstab and /etc/crypttab entries
and allow using them by the active user without a password prompt:

+---
| [Allow active user to mount x-udisks-auth filesystems]
| 
Action=org.freedesktop.udisks2.filesystem-fstab;org.freedesktop.udisks2.encrypted-unlock-crypttab
| ResultActive=yes
+---[ /etc/polkit-1/localauthority/50-local.d/x-udisks-auth.pkla ]

See man:pklocalauthority(8) for documentation of the *.pkla files.

Note that I haven't used PolicyKit that much, so some details might not
be quite correct.

Ah, and I just noticed that the "Identity=" is not optional.  So that
needs an additional

  Identity=unix-user:*

(Or a username instead of "*".)

The button you mentioned is the only way I know of to initiate a large
message download.

You'll probably get a better response on the Claws Mail mailing list.

They're likely to ask are whether this happens with only one mail

certainly mention that v3.9 is quite old, and that an upgrade might be

Hi Brad,

Thanks for your suggestions. In the meantime, I discovered a way to do what I 
wanted.
It's not a very elegant solution but workable. See below.

The file ~/.claws-mail/uidl/ACCOUNT_NAME seems to contain a list of the 
messages on the
server in a format like this:

732016110406345739451478266525  0
732016110406551661351478266525  0
732016110409085573471478266525  0
732016110409410406441478268386  0

The last field usually contains a 0 or 1 (I'm assuming '0' might mean 
'retrieved' and '1'
might mean 'not fully retrieved'). But if the 'Mark for Download' button is 
activated,
the entry for that message changes to something like:

732016110409410406441478268386  #mh/path/to/inbox:2180

where 2180 is the filename assigned by claws mail for that message. (I use 
maildir
format.) Knowing this, I can now manually edit the entry with the correct 
parameters and
claws mail retrieves the entire message without a hitch, at least it did for 
the one I
tried it on.

This would be somewhat awkward if I'd need to do it every day, but it works for 
getting
me out of an occasional pickle.

This needs a correction, if I'm not mistaken:

aptitude -F "%p" search ~i | sort | \
(aptitude -F "%p" search ~Aunstable ~Atesting | sort -u | \

All installed packages should be checked, not all available from stable.

Hi,

Elinks has an interactive configuration system accessible with
F10. What you need here is this:

F10 -> "Setup" -> "Options manager" -> "Protocols" (expand options
list with the '+' key) -> "HTTP" -> "User-agent identification" and
then push the "Edit" button. There you can craft your own
user-agent header. Setting it to " " causes Elinks to send no
user-agent header at all.

Or just with aptitude:

aptitude -F "%p" search '!~Atesting!~Aunstable~i'

At least on my system it produces the same list of packages.

as to the specifics that cindy-sue asked about, i'm thinking more about 
cyber-security and hardening systems.  one of the reasons that i'm looking at 
pen testing is for this, understanding the vulnerabilities of a system and then 
be able to tighten them up, maybe throw some cryptography in there.
also, when i did have my server, i was more interested in making sure that i

Problem attempting to use xorriso

[Richard Owlett]

Due to limited bandwidth I purchase complete sets of Debian 
install DVDs.
I had successfully created *.iso files for 12 of the 13 DVDs for 
version 8.6.
[The MD5SUM of one DVD does not match list at 
http://cdimage.debian.org/debian-cd/8.6.0/i386/iso-dvd/MD5SUMS]


I attempted to follow the example given by Thomas Schmitt in 
https://lists.debian.org/debian-user/2015/09/msg00421.html He had 
suggested:


  for i in /media/distributionA/DVD*.iso
  do
xorriso -osirrox on:auto_chmod_on -overwrite nondir \
-indev "$i" \
-extract /pool /media/distributionA/poolA
  done

To account for my current directory structure I had modified it 
to bee:


  for i in /media/root/jessie-dvds/dvd8_*.iso
  do
xorriso -osirrox on:auto_chmod_on -overwrite nondir \
-indev "$i" \
-extract /pool /media/myrepo/pool
  done

My running copy of Debian is on /dev/sda9 and had ~4GB of 10GB used.
When my run crashed it had no free space left.

Looks like the filesystem to which you copy is full.

Determine the device file and mount point of the destination by

  df /media/myrepo/pool/main/n/ns3

or if missing by the lowest existing directory above that path.

It should tell you something like

  Filesystem 1K-blocks Used Available Use% Mounted on
  /dev/sda3  490205312 23072576 442208680   5% /

but with "Use%" 99% or 100% and possible a mount path longer than "/".
That's where you would have to make room.


Have a nice day :)

Trivial script will NOT execute

[Richard Owlett]

Today I've been having weird problems executing scripts.
As I have no valuable data on the partition containing Debian, I 
wiped it and did a fresh install of Debian Jessie (8.6.0) MATE 
desktop environment from a purchased set of DVDs. Earlier today I 
had had reason to create an *,iso of DVD1 of 13 using xorriso. 
The ISO had a MD5SUM matching the one at debian.org .


More than a half-century of trouble shooting *screams* 'operator 
error' ;[

But what? [Caja reports the execute bit is set ;]

Cut-n-paste from MATE terminal:
root@full-jessier:~# #!/bin/bash -x
root@full-jessier:~# cd /media/root/myrepo
root@full-jessier:/media/root/myrepo# RCO
bash: RCO: command not found
root@full-jessier:/media/root/myrepo# ls
lost+found  new file  RCO  x2  xtract2 (copy)
root@full-jessier:/media/root/myrepo#


The content of RCO [with Linux line endings] is:

F='dvd8_'
N=0
E='.iso'
echo ""
while true
  do
read -p "press Enter (Ctrl+C to exit)" dummyvar
let N=N+1
FILENAME=$F$N$E
echo $FILENAME

By default for security reasons the current directory is not in the
PATH environment variable on Linux. Perhaps in your previous install
you had manually added it to your environment, but in a fresh
installation with an empty home directory (or at the very least
without restoring dotfiles in your home directory) it will not be
present.

You can add it to PATH via:

export PATH=$PATH:.

in the current shell. You can also add that line to your ~/.bashrc
to make that permanent. (Note that you appear to be running this as
root, so ~ means the home directory of the root user here, typically
/root.)

Please be aware of the security implications of this though; while
adding it to the end of PATH (as my line above does) is not quite as
bad as adding it in the front, this could lead you to potentially
running programs from untrusted sources. (Example scenario: you have
a command line open in a directory which contains an executable or a
script with the name of something you want to execute, you
accidentally removed the command a month ago during a system update;
in that case typing in that command will execute the binary/script
from the current directory - and if the current directory comes from
an untrusted source, because it's on an external pendrive that you
don't trust, for example, then it could lead you to executing
malicious code.)

Alternatively, what most people do is not add the current directory
to PATH explicitly. Because there's another way to call a script or
binary from the current directory, by explicitly telling the shell
what you want - in this case by prepending './'. In your case, you
can do

./RC0

and that will execute the script "RC0" in the current directory. It
will also be explicit that you are executing something from the
current directory and not a system command - which is why I prefer
to do it this way instead of tinkering with PATH here.

As a side note: your script RC0 doesn't appear to start with a
shebang line. In that case the script will be executed via /bin/sh,
so it will work regardless, but I would suggest to make that
explicit by having the script start with #!/bin/sh. (Or #!/bin/bash
if you need bash features in the script.)

Try specifying the full path name to the script, as in:

root@full-jessier:~# /media/root/myrepo/RCO

or

root@full-jessier:~# cd /media/root/myrepo
root@full-jessier:/media/root/myrepo# ./RCO

upgraded testing and now gpg is not working

[H.S.]

I upgraded my testing box last night and now my gpg decryption does not 
work anymore.


I have a file encrypted for myself which I have been using. Till 
recently I was able to decrypt it successfully for years.


After last night's upgrade, I get the following:
$> gpg -d somefile.txt.asc
gpg: encrypted with 2048-bit ELG key, ID , created 2012-02-01
  "my name and email here"
gpg: public key decryption failed: Timeout
gpg: decryption failed: No secret key

Is something broken in the updated GPG related package in testing?

Thanks.

I will never again permit "." in my $PATH since the day I tried to run

at the front of root's $PATH, so /etc/init.d/killall ran (part of the 
shutdown process) and left the system in an unusable hung state, 
requiring me to obtain physical access, perform a hard reset, and go

+1 for ./scriptname or scripts installed in well-defined bin directories 
that have a well-considered order on the $PATH.

I actually found out about the path issue as a brand new UNIX user
(OSF/1, to be exact) in 1994 (I was a die hard DOS user before that).
To this day, I have "." in my path, but last and only on my personal
account (never as root).

I do have ffmpeg, perhaps from jessie backports.


I thought I marked this thread resolved days ago.
I got it from backports, all set now.

Until a couple of months ago, gpg was gpg1. It's gpg2 now and you need 
to specify gpg1 explicitely if you want to use the 'classic' version. 
You may have to install the gnupg1 package first. This provides 
/usr/bin/gpg1 and I seem to remember it didn't get pulled in 
automatically on my testing machine.


gpg2 can't find your secret keys because it stores them elsewhere. For 
gpg1 they are in the secring.gpg file and gpg2 looks at the files in the 
private-keys-v1.d directory. If this directory does not exist inside 
your gnupg directory (probably ~/.gnupg), then the automatic migration 
failed somehow.
