The default settings for external drives is in /lib, offhand I can't
remember where filetypes is taken from (somewhere in /etc ?).  Take a
look at "udisks-doc" if you're interested. Most of udisks, as you've
discovered, is binary.

Another very quick comment as I haven't had a chance to do much Debian
User stuff lately (will get back to this and an Apple udev rule this
evening).

The udisk rule I pointed out above - is fine as it is, it hides
disk/slices that would normally need to be hidden.

I need to finish testing a custom udisks rule for you that changes the
default naming of new devices that have an ntfs file system to
/dev/$Label and a udev rule that runs fuser to automount the drive (to
/media/$Label. It can be done with just udev, but it's a crude hack
(doesn't cleanly umount, creates incrementing /media/usbN). Then you
should get the Thunar support you want for Plex.

Sorry for replying to my own post...

I see now that it's the XFCE's volume management that is initiating the
(hotplug) mount. Some digging found that "udisks" is involved, so I
attached strace to the udisks-daemon and found this:

[pid 29472] 10:58:32 execve("/sbin/mount.ntfs", ["/sbin/mount.ntfs",
"/dev/sdg2", "/media/WinBackup_", "-o",
"rw,nosuid,nodev,uhelper=udisks,uid=1000,gid=1000,dmask=0077,fmask=0177"],
[/* 3 vars */]) = 0

So the mode that I'd like to change is coming from the udisks-daemon (or
its parent). Strace on udevd shows that it's involved but I don't see
any file modes.

That's were I'm at now. I played with udev rules a bit but I've never
worked with them before.

Quick comment (I will get back to this later today or early tomorrow):-
grep ntfs /lib/udev/rules.d/*.rules
/lib/udev/rules.d/80-udisks.rules:ENV{ID_FS_TYPE}=="ntfs|vfat", \

If this does control the effect you note, (which is easy to determine),
then it's simple to create a rule based on it
(/etc/udev.d/$something.rule) that will treat your WinBackup disk
differently


I grabbed the src for udisks, but didn't get very far. It has code that 
checks fstab and uses its entries if found, but that code isn't used. It 
always makes a call to udev_glib instead.

Rick

If you want upstart, you can just install upstart instead of
sysvinit-core.

Runit is not configured to be directly replaced without manual
intervention. Install sysvinit-core or whatever, then run the manual
configuration to run runit as /sbin/init.

shutdown hangs 4+ minutes at "Stopping enhanced syslogd: rsyslog."

[Scott David Sutton]

Hello,

I found your thread and I wanted to add something I found on my system.
If I add additional drives (either network or internal) into the fstab 
file the system hangs for the 4+ minutes stated.

If I do not add the drives the system acts normally during shutdown/restart.

I also noted that if I mount these drives I cannot unmount them.
The system states that only the root can unmount them.
Hope this helps

My understanding of the way the Debian release codenames work / are used
is that current testing (AKA "the current testing release") is codenamed
jessie, and when it changes from being a testing release to being the
latest stable release it will still be codenamed jessie, and the new
testing will be - or, as the case happens to be, has been - given a new
codename.

Replacing systemd in Jessie

[Patrick Bartek]

It seems systemd cannot not be installed in Jessie.  It can only be replaced 
once first installed unless one wishes to create a custom CD with another init. 
 I don't.  Even preseeding won't accomplish this.  Recommended preseeding 
procedures I've seen just automate the replacement process.

Now the strange thing:  I've done some research, and it seems that all the init 
replacement procedures start with first replacing systemd with sysvinit, then 
proceeding with replacing sysvinit with the desired init.  Anyone have info or 
instructions to the contrary? I'd like to be able to just install the desired 
init without an intermediate step.

I'm concerned specifically with runit.

Thanks.

I thought I'd append a bit more and specifically the reason why it87
could not be loaded. In lm-sensors configuration for Wheezy, it said to
put two modules into /etc/modules: coretemp and it87. When lm-sensors
run under my current hardware with Jessie, it only says to add the
coretemp module. When I comment the it87, I no longer the the FAILURE
message during boot. 

My # sensors command no longer provides fan speeds and ALARM, which I'll
have to investigate some other time, but it seems it87 module not
relevant to this.

Linux entropy pool / random number benchmark

[David Christensen]

debian-user:

I found some informative articles about Linux and the Intel Secure Key 
processor feature:



https://software.intel.com/en-us/articles/performance-impact-of-intel-secure-key-on-openssl


http://blog.cloudflare.com/ensuring-randomness-with-linuxs-random-number-generator/


It appears that openssl gives you direct access to Secure Key, while the 
Linux kernel uses Secure Key to stir an entropy pool that is fed into 
SHA-1 to produce random numbers.  So, openssl and /dev/random should 
show speed improvements on a processor with Secure Key, and /dev/urandom 
should have better entropy.



Below please find a Perl script for benchmarking the Linux entropy pool 
and random numbers, and two sample runs on a Wheezy 7.7 i386 machine 
with a Pentium 4 3.4E GHz HT processor (does not have Secure Key):


1.  The first run was with an idling machine and a low entropy pool to 
begin with.


2.  The second run was started after rapidly typing random garbage into 
another terminal and continuing to type during the run.



Could somebody with a Secure Key processor please run the script and 
post the results?



David

The module supports the lm-sensors application that monitors hardware
state such as CPU temperatures and fans. In fact, with the # sensors
command I do get readings for the Jessie box, even though lm-sensors is 
not using the it87 module.

I find that on the reboot that I now connect to wlan0 automatically as
I would expect. Is it possible that removal of consolekit allowed the 
network interface to get the IP address from DHCP?

Thanks for the clarifications,

Haines

I am not qualified to give an answer to that, I usually trust upstream's
or the maintainer's defaults. You will probably receive the best answers
on OpenSSH related mailing lists. Maybe it is even already explained
there.

But, as far as I understand, if the key exchange algorithm is really
unsafe, the risk is probably that someone might eavesdrop on your
connection. This is especially problematic since you are using password
authentication because the password can be read as well (if the key
exchange is unsafe).

Perhaps 'apt-config dump' command helps to find out the proper order.

_netdev with wpa_supplicant dependency doesn't work at shutdown

[Javier Barroso]

Hello,

I'm trying to solve my own reported bug [1]

When I add a curlfs fstab entry via wifi (wpa_supplicant), it get
mount at boot, but it does not umount when system is halting / at
shutdown. Wpa_supplicant stop before than curlftpfs umount the mount
point (xx.mount).

I have been playing with "After  / Before /Requires" parameters both,
but I'm getting tired .. I'm not able to make it work :(

What I have tried:

1. Modify fstab-generator , so xx.mount depends on :
1.1 network-online.target
1.2 wpa_supplicant.service

2. Modify wpa_supplicant.service, so depends on:
2.1 xx.mount
2.2 remote-fs.target

Do you have any hint about this issue ? How can I get it working ?

How can I say to systemd about not stop wpa_supplicant until xx.mount
is umounted ??

Thank you very much

"rc" means you have some configuration files lying around your system.

apt-get purge pulseaudio will remove them.

If you follow the lines you will notice that 'r' means "Desired=Remove" 
and 'c' means "Status=Conf-files". In other words "removed but not 
purged".

You might want to 'apt-get purge pulseaudio' to eliminate the 
possibility that it's conffiles somehow interfere (though I doubt it).

On the other hand, your use-case is exactly what pulseaudio was designed 
to do, so you might want to try installing it instead.

Kind regards,
Andrei

Re: ntpd confusion

[mad]

I found it. It was DHCP. The NTP init scripts checks if there is a file
/var/lib/ntp/ntp.conf.dhcp in which the local router is configured as
only ntp source.

aa-logprof/aa-genprof not working after jessie upgrade

[Simon Brandmair]

Hi everyone,

I recently upgrade to jessie. I noticed now that aa-logprof/aa-genprof
(for apparmor) stopped working. When I try to create a new profile with
aa-genprof it doesn't add any rules while I see them in the logs. Same
with aa-logprof (both worked just fine in wheezy) . I don't know how to
debug this further. Is this a bug in the jessie packages or did I miss
something in the upgrade progress?

Cheers,
Simon

I'm not familiar with the it87 module, but do you actually have the
hardware which it controls?  If not, then it's not too surprising that
trying to load it fails with ENODEV.

No, it probably means that /usr was not mounted in the first place;
systemd-remount-fs expects that /usr is mounted by the initramfs which
is not the case for initramfs-tools in jessie.  This is rather harmless,
though.

This seems to be https://bugs.debian.org/718843.  Maybe you should just
remove consolekit, it's deprecated and replaced by systemd-logind.

No, this does not have anything to to with dbus AFAICS.

That's the problem, but without knowing how you connect to your router
(network-manager, ifupdown…) it's hard to tell why you don't get any
DHCPOFFERS from it.

and select the mesa option.
Or if you have a Nvidia Optimus configuration, try to use the Bumblelee  
drivers:

Statistically speaking, we can't help but have a biased sample unless
the ordinary user decides to take an interest in the problems others
have. Without that interest, they don't participate here, and that's
the reason the sample is biased.

But it would even help reduce the arguing if the ordinary user would
just take an interest in writing code.

Historically speaking, though, I don't think it's getting worse.

Okay, no pulseaudio.

This reference says you get dmix by default
for ALSA, version above 1.0.9rc2. So several
years.

http://alsa.opensrc.org/Dmix

You also want to make sure there is no asoundrc.

Probably you will get better help if you post
to Linux Audio Users mailing list.

It may help to know the output of

lspci

cat /proc/asound/cards

lsmod | grep snd


Hope this helps

Kill your net performance by disabling sg acceleration.  This is going to

Agreed. :)  dpkg -l says:

 dpkg -l |grep pulseaudio
ii  gstreamer0.10-pulseaudio:amd64 
0.10.31-3+nmu4+b1  amd64GStreamer plugin for
PulseAudio
ii  gstreamer1.0-pulseaudio:amd64   1.4.4-2   
amd64GStreamer plugin for PulseAudio
rc  pulseaudio  2.0-3 
amd64PulseAudio sound server

Maybe the 'rc' at the start of that line has a meaning I don't know? 
Anyway - it looks like pulseaudio is not actually present.  I agree, too,
that ALSA should allow mixing without extra configuration.  That's what it
had been doing for years, until a recent update apparently changed
something.

Would you mind just copy-pasting the output of above command?

BTW, interpreting the output of 'dpkg -l' would be easier if one would 
not use grep to strip the header with explanations and use only dpkg's 
built-in pattern support, in this particular case:

dpkg -l '*pulseaudio*'

AIUI, that if pulseaudio is running, your programs are
not getting direct access to ALSA. There is an additional
layer.

My expertise doesn't extend to pulse audio. I recall it adds
some convenience, like being able to provide a separate
volume control for each app, which can help in a GUI
environment. Nothing I need.

ALSA should default to mixing. You shouldn't need any
special asoundrc to get that.

I would be surprised if aptitude and dpkg reported
different status for the same package!

cheers,

Joel

Help understanding error: skb rides the rocket

[SL]

On one of our quite busy (virtual) Debian 6 servers we are seeing a lot of
messages in the syslog like this:

kernel: xen_netfront: xennet: skb rides the rocket: 19 slots

We are seeing some connectivity problems, and I believe it's possibly
related to this. I've tried researching the issue, but can find very little
information (but have confirmed that it can cause packet loss).

Since this is on a virtual machine and we don't have access to the physical
host, one problem is knowing at what level this problem lies.  I've tried
raising this issue with the hosting company in the past, but was basically
told that it wasn't their problem.  So now I don't really know how to move
forward with diagnosis of this issue.

OS: Debian 6, Kernel:  3.15.4-x86_64-linode45

- What might be causing this issue?
- Could this be a problem with the virtual host? (and why is Xen mentioned
here)
- What can I do to stop this happening?

Thank you for any help!

Sorry, no can do. Whenever a resolution by a project is taken with less
than consensus, and the losing party is determined to make an ass out of
themselves by being a very vocal obstructive minority, you will get
lawyering if you have *any* rules at all.

The problem is that some persons decided to use the Constitution in a
toxic manner, not the Constitution itself. This is not a unique problem
to Debian, and short of just shooting all opposition essentially
unsolvable.

Hi, Joel - Thanks. :)  Synaptic says "no" but running the dpkg -l command
indicates pulseaudio 2.0.3 is present. (!)  It isn't, but there's a fair
number of residual files around from some earlier install, including
things like the gstreamer1.0-pulseaudio plugin and PulseAudio client
libraries.  I don't _think_ there's anything there that would cause ALSA
to block...?
