[Bug 1336663] Re: lightdm uses wrong ccache name on pam_krb5 credentials refresh

2018-02-12 Thread Cédric Dufour
On Debian/Stretch - lightdm 1.18.3 - this issue is still present.

The script mentioned in comment 9 has served us well for the past 3+
years and is "maintained" on https://github.com/cedric-dufour/custom-
conf/tree/master/generic/all/custom-conf-pam-krb5/usr/share/custom-conf-
pam-krb5/config/etc/security/pam-script.d as part of our "standard"
Kerberos/PAM configuration.

2014-12-22 Thread Cédric Dufour
Hello again,

Thanks @Sergio for the krenew tip.

I'd rather not automatically renew a user ticket without having him
supply its password from time to time.

I came up with a *horrible* workaround which I believe does not break
the entire Kerberos security (please correct me if I'm wrong):


In /etc/pam.d/common-auth:
auth optional pam_script.so dir=/etc/security/pam-script.d


In /etc/security/pam-script.d/pam_script_auth:
#!/bin/sh

## Kerberos 5 credential cache (ticket) hack
#  REF: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1336663
sh -c sleep 3; PAM_USER=${PAM_USER} /etc/security/pam-script.d/krb5cc_rename 


In /etc/security/pam-script.d/krb5cc_rename:
#!/bin/sh

## Kerberos 5 credential cache (ticket) hack
#  REF: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1336663

# Parameters
KRB5CC_DIR='/tmp'

# Look for matching - although misnamed - credential cache
# ... retrieve user UID
KRB5CC_UID=$(id -u ${PAM_USER})
[ -z ${KRB5CC_UID} ]  echo 'ERROR: Failed to retrieve user UID'  exit 1
# ... look for user matching/misnamed ticket
KRB5CC_SRC=$(find ${KRB5CC_DIR} -maxdepth 1 -uid ${KRB5CC_UID} -name 
'krb5cc_0')
[ -z ${KRB5CC_SRC} ]  echo 'INFO: No matching/misnamed Kerberos 5 ticket 
found'  exit 0
# ... look for *older* user ticket (do not replace a newer one)
KRB5CC_DST=$(find ${KRB5CC_DIR} -maxdepth 1 -uid ${KRB5CC_UID} -name 
krb5cc_${KRB5CC_UID}_* -not -newer ${KRB5CC_SRC} | head -n 1)
[ -z ${KRB5CC_DST} ]  echo 'INFO: No previous/user Kerberos 5 ticket found' 
 exit 0
# ... check Kerberos principal matches (just to be on the safe side; let's not 
rely only on files ownership)
[ $(klist ${KRB5CC_SRC} | grep '^Default principal:') != $(klist 
${KRB5CC_DST} | grep '^Default principal:') ]  echo 'ERROR: Mismatched 
principal'  exit 1

# Replace user credential cache by matching/misnamed one
mv ${KRB5CC_SRC} ${KRB5CC_DST}
[ $? -ne 0 ]  echo 'ERROR: Failed to rename matching/misnamed Kerberos 5 
ticket'  exit 1
echo 'INFO: Successfully renamed matching/misnamed Kerberos 5 ticket'
exit 0


The 'sh -c sleep 3; ...' is required to handle the fact that the misnamed 
ticket is created only after pam_script is invoked (I guess when pam_end is 
called).

Gut-wrenching... but working :-/

[Bug 1292820] Re: xfce4-panel 4.11 does not honor compiz virtual horizontal size correctly

2014-04-19 Thread Cédric Dufour
Hello,
The problem comes from:
1. the pager does not use the 'wnck_workspace_get_{width,height}' to calculate 
its aspect ratio
2. the pager does not recalculate its aspect ratio when Compiz 
workspaces/viewports settings are changed
Please consider attached patch to fix this behavior.
Once applied, pager size is correct for both Compiz and XFWM4.

[Bug 1292820] [NEW] xfce4-panel 4.11 does not honor compiz virtual horizontal size correctly

2014-03-15 Thread Cédric Dufour
Public bug reported:

Hello,

When increasing compiz virtual horizontal size, xfce4-panel (4.11;
Ubuntu/Trusty) workspace swicther shows the additional workspaces but
without increasing the swicther width accordingly; the width remains as
if a single workspace is used, and compiz workspaces appear squeezed
within the available width (the more so as the virtual horizontal size
is increased).

Reverting to xfce4-panel 4.10 (Ubuntu/Saucy) fixes the issue.

Best,

[Bug 1251991] [NEW] [13.10] 'xfce4-power-manager' should depend on 'systemd-shim'

2013-11-17 Thread Cédric Dufour
Public bug reported:

Hello,

After updating from Ubuntu Quantla (12.10), my system (Dell XPS 12) would:
1. attempt to suspend when lid is clised (even though this behavior is disabled 
in 'xfce4-power-manager' settings); see bug #1222021
2. fail to suspend altogether when called from XFCE's 'Log Out - Suspend' 
button

Even though:
a. 'pm-suspend '(as root) works flawlessly = suspend/resume works
b. 'dbus-send --system --print-reply --dest=org.freedesktop.UPower 
/org/freedesktop/UPower org.freedesktop.UPower.Suspend' (as user) works 
flawlessly = DBus works

I finally tracked it down to the package 'systemd-shim' being missing
from my system.

I recovered a flawllesly working XFCE's suspend/hibernate/resume
behavior by:

A . Installing 'systemd-shim' (which apparently installs the glue
between XFCE's power manager, DBus and 'systemd'

B. Inihibiting 'systemd' behavior (which overrides/bypasses 'xfce4
-power-manager'; see bug #1222021); in '/etc/systemd/logind.conf':

HandlePowerKey=ignore
HandleSuspendKey=ignore
HandleHibernateKey=ignore
HandleLidSwitch=ignore

C. Addind the new 'logind'-related policies for hibernation; in
'/etc/polkit-1/localauthority/50-local.d/hibernate.pkla':

[EnableHibernate:LoginD]
Identity=unix-user:*
Action=org.freedesktop.login1.hibernate
ResultActive=yes
ResultAny=no

Unless I'm mistaken, 'systemd-shim' should be added as a dependency of
'xfce4-power-manager' to avoid some scenari stumbling o the same issue I
did.

Cheers and thanks,

Cédric

[Bug 1104156] Re: Continue to wait, or Press S to skip mounting or M for manual recovery when waiting for LUKS passphrase

2013-03-01 Thread Cédric Dufour
Hello again

I'm currently looking at plymouth source code and trying to find a
solution to elegantly solve the issue mentioned in this bug at the
plymouth level, as Steve Langasek suggests.

Unfortunately, I'm wondering whether this can be achieved.

Plymouth seems to be totally agnostic of where client requests come from
(except to know where to send replies back) and to what purpose (and
thus can not know anything of the logic which may bind some requests to
others). Am I right in this regard?

This means that one could improve the handling of interactive requests
that depend on keyboard input (password prompt, question, waiting for
keystroke) and avoid to display the corresponding prompt message as long
a preceding interactive request is still unanswered (or not canceled).
This is possible (and already dealt with at some level) because keyboard
input can only match the latest pending request.

BUT I don't see how one could filter out messages to be displayed based on 
other interactive requests.
While plymouth should not display mountall boredom messages while cryptsetup 
is waiting for password input, I'm sure there are existing use cases where 
messages from one client must be displayed regardless of the interactive 
request(s) of other(s). How can plymouth tell the difference?

Thank you for your replies

Cédric

[Bug 1104156] Re: Continue to wait, or Press S to skip mounting or M for manual recovery when waiting for LUKS passphrase

2013-02-04 Thread Cédric Dufour
Hello,

In the case of this cryptsetup(passphrase)/mountall(prompt) concurrency,
I agree with you.

Note that this issue also presents itself when not using plymouth
(though the passphrase prompt would hide the mountall boredom until
the 'return' key is pressed). The mountall boredom message will pop up
none the less after the passphrase is (successfully or unsucessfully)
provided.

However, I think that hard-coding a 3-second timeout in the source code
is not a good idea. Timeouts should be configureable.

Thanks and cheers

2013-02-04 Thread Cédric Dufour
Hello Steve,

Thanks for your comments.

As for no case in which plymouth is not used: I'm afraid I grossly 
misunderstand when plymouth is used.
I experimented the command-line behavior I described above when booting in 
recovery mode.
Is plymouth also used in recovery mode or when one removes the 'splash' 
parameter from the kernel boot options?
cryptsetup provisions for when plymouth is not installed/active; in 
'/lib/cryptsetup/cryptdisks.functions', function 'do_luks':
[...]
if [ -x /bin/plymouth ]  plymouth --ping; then
KEYSCRIPT=plymouth ask-for-password --prompt
keyscriptarg=$(printf $keyscriptarg)
else
KEYSCRIPT=/lib/cryptsetup/askpass
fi
[...]

But not a big issue I agree. Merely an esthetic one.

2013-01-31 Thread Cédric Dufour
ERRATA: 'i915.invert_brightness=1' is *not* the way to go. Brightness is
actually handled correclty... but when booting the XPS 12 with 3.8rc5,
brightness is by default set to its minimum value (iow. off). One just
needs to increase it with Fn+F5 to have the panel wake up.

Note that this issue is also solved in the Quantal kernel, which, if I
read correctly, incorporates all the quirks - for the brightness,
trackpad, etc. - that have been developed as part of the Dell/Ubuntu
Sputnik project (for the XPS 13). It appears none of this quirks are
mainstream as per 3.8rc5 :-(

It is impossible to boot, supposedly because of i915/Intel HD4000 issues. 
Normal boot leads to black screen (backlight turns off); Recovery mode 
leads to garbled output.

Should I file a separate bug addressing the this i915/Intel HD4000 with

[Bug 1061190] Re: could not mount /dev/mapper/cryptswap1 M for manual S for skip

2013-01-24 Thread Cédric Dufour
Hello,

On Quantal, I've been trying to get rid of this message on my system
when using LUKS (passphrase-protected) encrypted LVM partitions.

Looking at the source code of mountall.c, it appears the Continue to
wait [...] S to skip or M for recovery (warning) message is triggered
by the (recurrent) boredom (hardcoded) 3-second timeout. When using
passphrase, there are good chances that mountall will get bored (thus
the message). Could it be that this 3-seconds timeout is also reached in
this (bug) case?

In the end, the partition gets mounted and the boot process continues.

I have found no logic in the mountall source code that allows it to detect 
cryptsetup-ped resources and be a little more patient.
I was wondering whether a (fstab) quiet option may be useful to silence 
those boredom messages in mountall. But then, it might not be such a good 
idea to remove the M for recovery option in case something is really wrong 
with the resource. But further on, the M/S keypress will most likely not reach 
mountall when plymouth (or the console) is waiting for a passphrase (cf. the 
crypsetup/askpass script).
Maybe a bepatient (fstab) option would be more appropriate. If mountall gets 
bored on a mountpoint which has that option, we would discard the initial 
boredom message and change the boredom timeout to something bigger (and 
then show the boredom message only after that longer delay).
PS: I also have found no code matching the documented --quiet option of 
mountall.

What do you think? (I'll send a patch if you deem the proposed option(s)
acceptable)

Cédric

[Bug 1104156] [NEW] Continue to wait, or Press S to skip mounting or M for manual recovery when waiting for LUKS passphrase

2013-01-24 Thread Cédric Dufour
Public bug reported:

Hello,

(On Quantal) When using passphrase-protected LUKS encryped partition,
'mountall' shows the Continue to wait, or Press S to skip mounting or M
for manual recovery after the (hardcoded) 3-second BOREDOM_TIMEOUT.

This is:
 - inappropriate as long as a passphrase is being prompted for
 - useless since the prompt intercepts the key presses (and prevents the S or M 
option to be used)
 - inelegant (any potentially misleading)

I first thought of adding a mountpoint-specific option to disable
boredom messages for appropriate mountpoints. But adding yet-another
option to the mountpoint stanza somehow seemed wrong.

On the other hand, if cryptsetup fails after several passphrase attemps,
one should still be given the choice to Skip or Manually recover the
partition.

I don't know how to handle a state tracking between 'cryptsetup' and
'mountall', so that 'mountall' does not get bored as long as a
passphrase is being prompted for.

The best way I found to make that issue less invasive is to allow the
boredom timeout to being extended (globally) when a particular system
setup requires it.

I thus attach a patch that allows to change the boredom timeout to the
dev_wait_time (or ROOTDELAY, if it is undefined) via a new '--be-
patient' option and configuration variables in /etc/default/mountall.

Corresponding patched Quantal 'mountall' package should be available
shortly from https://launchpad.net/~cedric.dufour/+archive/ppa/

Hope it can help.

[Bug 1073108] [NEW] grub-pc fails to boot (system resets after GRUB prompt) on degraded RAID

2012-10-30 Thread Cédric Dufour
Public bug reported:

When a RAID1 system is degraded (e.g. unplug /dev/sdb, leaving obnly
/dev/sda), grub-pc properly enters prompt but system is reset as soon as
one attemps to boot OR one enters the command-line and issue the 'ls'
command.

This bug is known (and presumably fixed) to Debian: 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=626853
Shortly put: adding the 'GRUB_TERMINAL=console' to '/etc/default/grub' (and 
executing 'update-grub' afterwards) allows to circumvent the issue (verified on 
Ubuntu/Quantal 12.10).

I believe this bug is critical because it shows up only when a disk
fails but remains latent on a healthy system.

Cheers

[Bug 1052076] [NEW] Widgets stop responding when enabling gestures on (evdev) multitouch device

2012-09-17 Thread Cédric Dufour
Public bug reported:

Hello,

Using Qt 4.8.2 on Ubuntu/Quantal (amd64) on a touchscreen device
(Samsung XE700, Atmel MaxTouch, stock hid-multitouch+evdev driver), I
found out that all widgets stop to work - iow. react to single-finger
touch (mouse press) - as soon as one enables a gesture - e.g.
grabGesture( Qt::PinchGesture ) - on a widget.

What is weird is that enabling the Tap gesture on a non-responding
widget makes it reponsive again. But one can not go into enabling the
Tap gesture on all widgets in an application (I have an application with
hundreds of them, some I can't even access; e.g. the close button on
QStackWidget tabs)

I attach a simple test case that allows to reproduce the problem
systematically (see README for further details).

Let me know if I can help.

Best regards,

Cédric Dufour

[Bug 901630] Re: multitouch + qt doesn't work (eg fingerpaint demo) with wacom serial touchscreen

2012-09-14 Thread Cédric Dufour
Hello,
Can someone clarify where we stand in regard with this issue and Ubuntu Quantal 
12.10?
I've been following Qt doc to the letter and got QPinchGesture working in a 
QWidget... but as soon as the grabGesture is issued on that widget all other 
widgets (tabs, pushbuttons, lineedits, etc.) stop responding to click (tap).
Where does the problem lie?
Can it be fixed or shall one forget to have that gesture-stuff working along 
evdev (at least as far as 12.10 is concerned)?
Thanks for your answer.

Hello Martin,
Yes indeed, it seems we're bumping is several different issues. Yours - and its 
fix - helped improve the global picture. I have absolutely no understanding of 
how all that X and multi-touch works, so I don't know where to start from (in 
respect with where/how to report the other issues). All I can do is give as 
detailed a report as possible, so those who know can extract what hopefully 
useful information they can (and maybe point some directions for further bug 
reporting and/or testing).
Thanks for keeping up with me so far ;-)

Thank you for looking into this.
When not subscribed to the X.org mailing list, obtaining the patch is kind of a 
hassle (I couldn't find a download option and I'd rather avoid copy/paste). Can 
you post it here too, so we can download/test it? Or will it be included in the

[Bug 1015183] Re: Inconsistent mouse events for Acer T231H multitouch monitor

2012-07-04 Thread Cédric Dufour
Hello,

Thanks Martin for your PPA and the precise packages; unfortunately, I
run amd64 :-/

I first applied only #19 patch (yes, it did require some adjustments) to
the latest precise X.org packages (1.11.4-0ubuntu10.3): behavior remains
the same (at least as far as Compiz plugins are concerned: Expo
triggers the issue systematically, Shift Switcher one time out of
two).

Then I saw Martin's comment and applied patches #11 and #19: behavior
remains the same (as far as Compiz plugins...) AND windows moving
(clicking-holding-dragging) is lost right from the start.

I think we can conclude that #11 triggers the windows moving (clicking-
holding-dragging) is lost issue (since I also bumped into it #17)

Now, I'm wondering whether Compiz might have some problem on its own.
Example given: I loose single/double click as soon as I launch the
Expo plugin and select (double-click on) a viewport. After, no amount
of single/double-clicking does anything (on desktop icons, windows
minimize/maximize/close buttons, panel applets, etc.). BUT, single
/double-clicking still work in Compiz plugin (if I launch the Expo or
Shift Switcher, single/double-clicking works).

I also gave #19 patch (alone) a try without launching Compiz (use metacity 
alone instead) or multi-touch (ginn) stuff. Before, even in that 
(no-compiz/no-ginn) scenario, single/double-clicking got lost rather rapidly. 
Here, I've been clicking and double-clicking around and using applications for 
several minutes without any problem. As soon as I launch ginn again, I start to 
have some problems with the applets icons (most of the time, they don't react 
to single click, though they sometime - rarely - still do). Other 
single/double-clicking still works.
Launching Compiz alone (without ginn), and all problems are back.

Conclusion using patch #19, without patch #11 (cf. windows moving
(clicking-holding-dragging) is lost issue), without Compiz (cf. single
/double-clicking is lost issue) and without ginn (cf. applets react
only whimsically to single-click issue), single/double-clicking at
least seems to work reliably enough to allow the touchscreen to be used
(before, it was a no go), even if sometime, one must (single) click
two time on an icon for the expected behavior to happen.

About that sometime, one must (single) click two time on an icon for
the expected behavior to happen: I can reproduce the behavior
systematically by: 1. clicking on a network-manager icon (menu opens),
2. clicking on the desktop to close the menu (menu closes), 3. clicking
on a network-manager icon again (menu does not open; instead, a
selection rectangle is drawn), 4. clicking on a network-manager icon
again (this time, menu opens again)

Let me know if I can help any further.

I applied the patches in #11 and #12 to the current precise xserver-xorg-core 
source (1.11.4-0ubuntu10.2) and unfortunately, it does not solve the atmel 
maXtouch loss of single click (I can reproduce that behavior systematically 
by calling Compiz's Expo plugin and double-clicking one of the viewport; after 
that single-click is lost).
Worse, drag'n drop does not work anylonger (e.g. to move a window by 
cliking-holding-moving its title bar).
Sorry for the negative report.

[Bug 1016592] [NEW] libnss-ldap should not depend on libpam-ldap

2012-06-22 Thread Cédric Dufour
Public bug reported:

On Ubuntu 12.04, libnss-ldap (264-2.2ubuntu2) should not depend on
libpam-ldap (via ldap-auth-config and ldap-auth-client).

Currently, if one installs libnss-ldap, libpam-ldap also gets installed
through dependencies.

Installing LDAP name services does not - should not, actually - imply requiring 
authentication via LDAP.
On Debian, there is no such dependency.

Thank you for considering this suggestion.

Best,

Cédric

2012-06-22 Thread Cédric Dufour
Thanks for your answer.

We actually have install-recommends disabled in /etc/apt/apt.conf.d

If you look closely, you will see that libnss-lap depends on ldap-auth-
config, which in turn depends on ldap-auth-client, which in turn depends
on libpam-ldap (thus the indirect dependency).

Debian has no such ldap-auth-config package (and thus dependencies).

In the end, maybe the problem lies more with the ldap-auth-config itself
depending on ldap-auth-client. I understand the ldap-auth-config allows
the seeding of the debcond database with the appropriate LDAP parameters
for libnss-ldap to work. So maybe the the issue should be addressed at
the level (by the maintainers) of the ldap-auth-config package rather
than linnss-ldap's. Your call.

Best,

Cédric

[Bug 293311] Re: nautilus thumbnails files on a mounted NFS share

2012-03-13 Thread Cédric Dufour
nfs shares are usually local: this is completely counter-intuitive. NFS = 
Network File System. I think most would agree than a network file system is 
definitely not a local one (and would rightly so, when considering the 
differences in terms of access latencies).
Even on a high-bandwidth LAN (with 10GbE and 500+ Gb/s core switching 
capacity), having Nautilus preview feature enabled by default on NFS shares 
just throws our filers down, thanks to thumbnailing kicking in when users 
browse their 20'000+ (scientific research) videos folder.

[Bug 585092] Re: giant IO delays on unmount

2011-03-01 Thread Cédric Dufour
Hello all,

The fix released to address this bug's issue unfortunately leads to problem for 
those who use the Lustre filesystem (see http://www.lustre.org):
 - kernel hangs when attempting to mount a Lustre filesystem with the wrong 
NID (which fortunately should not happen in normal operating conditions)
 - *huge* amount of warn_slowpath messages in the kernel logs as soon as 
files are created or stat-ed on the mounted Lustre filesystem(s), resulting in 
degraded performances (~30%) and very fast log clogging (kern.log file growing 
to 1.5GB during a single bonnie++ test of 30 minutes); see attached file for 
/var/log/kern.log exerpts

In order to fix those issues, we had to revert the commits mentioned in comment 
44 ; more precisely:
# git clone git://kernel.ubuntu.com/ubuntu/ubuntu-lucid.git
# cd ubuntu-lucid/
# git diff -R fb743c6...a192aa1  2.6.32-28-writeback-revert.patch
(and apply the patch to the Ubuntu/Lucid Linux kernel source package before 
building new kernel packages)

I hope this may help those unfortunates who stumble on the same problem.

Cheers

And I would add to #44, #45 and #46 that Canonical can not honestly
ignore the fact that LTS releases are certainly preferred by
enterprise/production environments, for obvious reasons (well, my

[Bug 608774] [NEW] Nautilus should honor the HAL setting 'storage.automount_enabled_hint'

2010-07-22 Thread Cédric Dufour
Public bug reported:

Binary package hint: nautilus

Hello,

Some use cases (e.g. using a USB key as an authentication token along
with 'pamusb') require automount to be disabled for specific drive(s)
(rather than globally for all drives, using for example 'gconf-editor -
apps - nautilus - preferences - media_automount = false')

This could be achieved using HAL policies. Example given (in 
/etc/hal/fdi/policy/my-policy.fdi):
deviceinfo version=0.2
  device
match key=storage.serial string=some-serial-discovered-with-lshal
  merge key=storage.automount_enabled_hint type=boolfalse/merge
  merge key=volume.policy.should_mount type=boolfalse/merge
  merge key=volume.ignore type=booltrue/merge
/match
  /device
/deviceinfo

Unfortunately, in Lucid Lynx 10.04, this does not seem to work
(anylonger?).

Nautilus should honor (at least one of) the possible HAL settings listed
above.

Or is there a new recommended way to achieve this behavior?

Cheers

2010-07-22 Thread Cédric Dufour
Thanks for the quick feedback.

So, for others who may be lost like me, the new 'udev' way is (in 
/etc/udev/rules.d/99-my-rule.rules):
# Exclude my USB token (cf. pamusb) from automount
# NOTE: use 'udevadm test /sys/block/sdX' to find the ENV{ID_SERIAL} parameter
SUBSYSTEM==block, ENV{ID_SERIAL}=, ENV{UDISKS_PRESENTATION_NOPOLICY}=1

(See http://manpages.ubuntu.com/manpages/lucid/man7/udisks.7.html ,
http://manpages.ubuntu.com/manpages/lucid/man7/udev.7.html, and
http://manpages.ubuntu.com/manpages/lucid/man8/udevadm.8.html for
further info)

[Bug 568082] Re: init: statd main process ended, respawning upstart problem

2010-04-22 Thread Cédric Dufour
Thanx Steve for feedback.
Yes, I do have a separate /var partition (LVM). So I guess all I achieved with 
the networking condition is to add enough delay so that /var is mounted when 
statd starts. Actually, I can confirm the fsck for this /var partition always 
comes after the statd main process ended errors. So I guess it makes this bug 
a duplicate of the other /var related bugs.
OT: can you point me to the way to enable debug/verbosity in the upstart 
process? I search for that feature a lot, to no avail.

Besides - sorry for being slightly off-topic, but - the supplied

[Bug 543838] Re: unable to create filesystem on 7.5TB partition with lucid beta

2010-04-09 Thread Cédric Dufour
In the mean time, I've been able to circumvent this bug and finish the
installation process normally (using the Alternate CD beta-1 amd64 ISO
image) by:

1. creating the physical partitions (fdisk) using the debian-installer's
partition manager

2. [CTRL+ALT+F2] creating the RAID array manually:
mdadm --create /dev/mdX --level=5 --raid-devices=4 --chunk=256 /dev/sd[abcd]X  
# I chose to use 256k chunk size

3. creating LVM volumes manually:
pvcreate /dev/mdX  # NB: LVM seems to recognize the chunk size and align 
optimally, cf. pvs -o +pe_start
vgcreate vg.raid5 /dev/md2
lvcreate -n lv.root -L10G vg.raid5
lvcreate -n lv.var -L10G vg.raid5
lvcreate -n lv.tmp -L10G vg.raid5

4. [CTRL+ALT+F1] Click on Go Back in the debian-installer partition
manager and click on Partition Disks again (partition layout is
refreshed); the error is still there (and the /dev/mdX itself can not be
used directly) BUT the logical volumes are there and available for use.
At the end of the installation, the system reboot and starts flawlessly
(the RAID configuration is created successfully by the debian-installer,
despite the error displayed by 'parted'

5. Create any big logical volumes you need (see 3.) once rebooted

PS: even though LVM was used on top of RAID5, bonnie++ performances
match what can be expected of the setup (120MB/s block write, 300MB/s
block read).

Still a hack, but allows to go through the installation process. Hopes
this helps

[Bug 533029] Re: autofs5-ldap doesn't work immediately after bootup

2010-03-22 Thread Cédric Dufour
I had the same problem and incompletely hacked a solution as in
https://bugs.launchpad.net/ubuntu/+source/autofs/+bug/511245/comments/5.
Maybe it can help.

[Bug 449198] Re: No GUI option to change login theme

2010-03-19 Thread Cédric Dufour
I just found out that all the 'sudo -u gdm gconf-editor  etc.' hacks
were just wiped out by the latest GDM update (because the %gconf...
files in /var/lib/gdm got overwritten).

We need to find a way to allow customization of GDM in a way that
resists update, via a sensible '/etc/gdm/custom.conf' file and without
reverting to horrible hacks like the CTRL-ALT-F1 + sudo + 

While I can live with lack of wallpaper and time format customization
(thought I'd rather not), I must ensure a few other parameters are
enforced, like getting rid of the users list.

Could we imagine some automated script that would get executed when
X/GDM launches (e.g. via '.xsession', IIRC), that would push some
parameters in the GDM configuration from a /etc/gdm/custom.conf file via
'gconftool-2' ?

[Bug 511245] Re: portmap is not started during boot process before autofs and hence autofs does not work properly

2010-03-17 Thread Cédric Dufour
The problem is the same for NIS:
https://bugs.launchpad.net/ubuntu/+source/autofs/+bug/119660

I do agree that porting autofs to upstart would be ideal. Unfortunately,
it seems it requires a good knowledge of Ubuntu's upstart events chain
to do it properly. Maybe someone knowledgeable enough with the latter
can come up with an elegant rewrite of
https://bugs.launchpad.net/ubuntu/+source/autofs/+bug/119660/comments/17

I had in mind something like /etc/init/autofs-ldap.conf (that would be part of 
the autofs5-ldap package):
[...]
start on (started rc-sysinit and started portmap)
[...]
script
  [ -e /usr/lib/autofs/lookup_ldap.so ] || exit 0
  /etc/init.d/autofs restart
end script

Would that do the trick elegantly enough ?

[Bug 511245] Re: portmap is not started during boot process before autofs and hence autofs does not work properly

2010-03-17 Thread Cédric Dufour
After a few reboot, it seems I found the quick-'n-elegant fix for that
issue:

r...@lucid-golden:~ # cat /etc/init/autofs-ldap.conf 
# Restart AutoFS-LDAP after everything has settled
start on (stopped networking and stopped rc RUNLEVEL=[2345])
exec /etc/init.d/autofs restart

Problem with depending on 'portmap' is that it may not be installed
(since 'autofs5' only recommends 'nfs-common' and indirectly 'portmap')
and may not be necessary (it seems one may use autofs-ldap to mount
other-than-NFS network filesystem, e.g. CIFS).

Now comes the issue of a (ported) /etc/init/autofs.conf: should it
necessarily depend on 'networking' (and thus make the /etc/init/autofs-
ldap.conf unnecessary) or can we imagine that autofs may be used for
non-network filesystems (and should thus not depend on 'networking';
/etc/init/autofs-ldap.conf should thus be kept separate, with the
'networking' dependency but without the 'rc' one) ?

Hope this helps. Cheers

[Bug 515678] Re: [needs-packaging] sun-java6 for lucid

2010-03-17 Thread Cédric Dufour
Me too
@Matthias (as a java developer one would develop against a specification, not 
a product): I'd agree with you if we all took the blue pill (and lived in that 
fantasy world where everyone behaves sensibly). Unfortunately, most of us had 
to choose the red pill and live in the real world (as much as it bothers me to 
say so).
Thank you for making sun-java6 available in the partner repo!

[Bug 511245] Re: portmap is not started during boot process before autofs and hence autofs does not work properly

2010-03-11 Thread Cédric Dufour
I'm experiencing the (same?) problem with Lucid (and autofs-ldap).
After rebooting, one time it works... another time not (until autofs is 
manually restarted)
That does sound like an upstart race condition.
Unfortunately, this is quite important for enterprise environments :-(
I guess at the time being, one can live with a dirty hack in /etc/rc.local:
sh -c sleep 15; /etc/init.d/autofs restart

[Bug 432598] Re: Do not show suspend/hiberate related UI if suspend is disabled in polkit

2010-02-14 Thread Cédric Dufour
On Lucid, it would seem the /etc/polkit-1/* folders are not used.

Puting a power.conf file:

[Disable suspend]
Identity=unix-user:*
Action=org.freedesktop.devicekit.power.suspend
ResultActive=no
ResultAny=no

[Disable hibernate]
Identity=unix-user:*
Action=org.freedesktop.devicekit.power.hibernate
ResultActive=no
ResultAny=no

[Disable shutdown]
Identity=unix-user:*
Action=org.freedesktop.consolekit.system.stop
ResultActive=no
ResultAny=no

In:
 - /etc/polkit-1/localauthority/50-local.d
 - /etc/polkit-1/localauthority.conf.d

Does NOT affect the applied policy (cf. pkcheck and Gnome shutdown
dialog)

Modifying the /usr/share/polkit-1/actions/* files DOES lead to the
expected results (cf. pkcheck and Gnome shutdown dialog)

Am I:
 - missing something (like reloading a daemon somewhere)
 - or is this a bug; a sysadmin would expect his custom settings to be in 
/etc/polkit-1 and be honored (and not be erased by some package update) ?

The /etc/polkit-1/localauthority/*.d files ARE honored, provided the

[Bug 434232] Re: cryptsetup prompt is overriden by upstart and xsplash in Karmic

2009-10-31 Thread Cédric Dufour
Well, the EXACT (and USB-disk-proof) syntax is:
  echo 'target=#TARGET#,source=/dev/disk/by-uuid/#UUID#'  
/etc/initramfs-tools/conf.d/cryptroot
(thus leading to a '/dev/mapper/#TARGET#' device; otherwise, you get a 
'/dev/mapper/cryptroot' device)

Also, make sure to add the proper modules in '/etc/initramfs-tools/modules'. 
Mine are:
  dm_crypt
  aes_i586
  gf128mul
  lrw
(this depends on which ciphers you use; 'diff' the 'lsmod' output before/after 
activating the LUKS partition to find out which additional modules may be 
needed)

As for best practices: I personally see no benefits (more like
drawbacks) in encrypting my system libraries, executables, package
cache, etc. on a netbook with a slow CPU...

Cheers
