-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Dear Members,

I'd like to announce the availability of the first beta release of my
tomld project.

This is a deamon managing fully automatic MAC configuration without any
user interaction.

(supported platforms are: Debian 6 and up, Ubuntu 10.10 and up)

My site:
http://log69.com/tomld_en.html

FAQ:
http://log69.com/help_en.html

Screenshot:

You can also find a video of a quick installation:
http://www.youtube.com/watch?v=8pfjuU94of4
http://log69.com/extras/tomld038_ubuntu1104_install.ogv

The code is in beta status, but I'm already using and testing it in
smaller production environments. Once i have a stable version, I'll get
it into Debian as a package.

Every suggestion and feedback are welcome!


Regards,

Andras Horvath

Somehow, I've had the -k options order reversed in the code
above.  It should've read: … | sort -n -k 1,1 -k 3,3 | …
instead.

Note that there we're sorting numerically on the first field,
too.  If that's undesirable, sort(1) is to be invoked twice,
like: … | sort -n -k 3,3 | sort -s -k 1,1 | ….

I'd like to try this. Can you give some details of what you did?
1. How did you partition the hard disk?
2. Did you put a file system on the partition?  I'm thinking of
using a 100G hard disk that I already have and I'd like to save
most of it for general backup of system files. Can I do this?
Does putting a partition table on it help save some the left
over space?

3. What did you us to write the image? dd ? something else?


I simply used  "dd if=netinst.iso of=/dev/sdX". The image contains a 
partition table and everything.



4. Is there something else that I should be asking about?


Not that I'm aware of. Just install as normal. Have fun :-)

As some of my test systems are very low on memory (32MB), and can't be 
upgraded, I created a swap partition on the rest of the disk, used 
Expert mode and activated swap as soon as I could in order to complete 
the installation. This shouldn't be necessary on a more modern system.

+1 if one has the hardware vm's offer any combo of os's/apps one could want. I 
use 
Virtualbox and run several vm's over multiple monitors, even a Windows NT4, but 
Debian stable is the host with the  most :-)

Unfortunately, the numeric (-n) sort cannot be performed over
the field that contains numbers prefixed with arbitrary strings.
Therefore, it's necessary to split such a field into the
separate prefix and number parts, like (assuming GNU Sed):

$ sed -e 's/^\(\s*\w\+\s\+[^0-9[:blank:]]\+\)\([[:digit:]]\+\)/\1 \2/' 
 238CHO   C10 3617   1.697   5.334   9.317

^D
 238CHO   C 10 3617   1.697   5.334   9.317
 238CHO   C 11 3624   1.665   5.468   9.092
$ 

Then, the output may be sorted on the now-third column, and the
extra space removed.  Thus:

$ sed -e 's/^\(\s*\w\+\s\+[^0-9[:blank:]]\+\)\([[:digit:]]\+\)/\1 \2/' \
  | sort -nk 3,3 -k1,1 \
  | sed -e 's/^\(\s*\w\+\s\+[^0-9[:blank:]]\+\)\s\([[:digit:]]\+\)/\1\2/'

To state it explicitly: I haven't tested X with kernel's i915
and without fbcon — only X without /either/ of i915 and fbcon.

I hope to check whether the respective kernel modules can be
“blacklisted” via modprobe.conf(5) shortly.

--cut: /etc/modprobe.d/blacklist --
# This file lists modules which will not be loaded as the result of
# alias expansion, with the purpose of preventing the hotplug subsystem
# to load them. It does not affect autoloading of modules by the kernel.
# This file is provided by the udev package.
--cut: /etc/modprobe.d/blacklist --

(But I still wonder, is this the hotplug subsystem that loads
the modules in question, or is it the kernel?)

cryptdisks runlevel configuration for lvm2 + encrypted swap file

2011-07-26 Thread Jimmy Wu
Dear List,

I have an encrypted swap file located inside /var, which is on a 
separate LVM2 logical volume from /, but it does not get mounted on 
boot.  Everything I've been able to find either implies my setup should 
work or is geared toward swap partitions, not swap files.  I even put 
aside my reservations about messing with the links in rc.d, (tried 
starting cryptdisks in runlevels 2-5 and other things as well) but since 
it didn't work so I restored everything back to the default before I 
broke anything, and came here to ask for help/advice instead.

I've copied the following relevant info below:
/etc/crypttab contents
relevant /etc/fstab entries
relevant rc?.d symlinks

My system is Squeeze 2.6.32-5-amd64 
Running invoke-rc.d cryptdisks start && swapon -a after boot works.
During the boot process I can see messages on the console that show
"Starting early crypto disks" succeeds, but "Starting remaining crypto 
disks" failed.

I'd appreciate any pointers as to what I am doing wrong or how I can 
better troubleshoot the problem.

Thanks,

Jimmy

Yeah, I've done this in the past, but my experience, especially on
laptops, is that a good configuration is a fragile thing.  Fortunately I
stick with older window managers, but my experiences with GNOME and KDE
changing out from under me have been particularly traumatic.

I actually am pinning stable right now with unstable sources available.
My experience going down that route though is that it's a short trip to
frustration.

I like running Stable machines.  But web browsers need to keep
current.  It would be great if they were in squeeze-updates, aka the
old volatile.  So instead I run a Sid chroot and install Firefox and
Chromium there and run them out of the chroot.  It is a little more
work to set up.  I create the chroot with deboostrap and then install
everything needed.  And it uses a significant amount of disk space.
But it works very well for me to keep my desktop Stable but have the
latest web browsers from Unstable Sid.

It definitely is not on mine.  Not on Lenny, Squeeze, nor Sid.  I just
double checked by doing the tests.  Variable settings in .bashrc are
not available to GNOME.

I didn't say anything about launching GNOME manually.  Not sure where
you read that from.  Although you certainly can do so through xinit or
startx and many do use those to start up X manually.

What I said was that setting shell variables in .bashrc won't normally
have any presence to applications launched by GNOME.  GNOME is
normally started by gdm, as you so noted.  That doesn't come through
either .bash_profile or .bashrc and so variables set there won't be in
effect.

So let's say you have GNOME preferences configured so that the web
browser will be sensible-browser.  In that case it won't get the
BROWSER variable setting in .bashrc and then won't launch the desired
browser.

I think it is actually better to do the variable setting through
~/.xsession.  It certainly isn't an obvious solution though.  In any
case it has been discussed to death on the mailing list previously so
I will avoid it again here.  The 55gnome-session_gnomerc seems to want
those in a ~/.gnomerc file.

I'd like to try this. Can you give some details of what you did?
1. How did you partition the hard disk? 
2. Did you put a file system on the partition?  I'm thinking of
using a 100G hard disk that I already have and I'd like to save
most of it for general backup of system files. Can I do this?
Does putting a partition table on it help save some the left
over space?

3. What did you us to write the image? dd ? something else?

4. Is there something else that I should be asking about?

doubt it.  hasn't happened since I first found the problem - almost 2 days.

looking through old kernel bug reports this program has reared it's ugly head 
more than once.

one person reported that it was reproducible when playing video.

I am almost certain that it was coincident with a web page I had up, just not 
sure which one..

probably flash related being that flash is evil.

Very encouraging.  Not everyone's like this.  I have a Canon and their
support is not good.  Their web site boasts drivers for Linux
(including .deb files) but by following their instructions the printer
is not installed into CUPS and gives an error message (can't remember
what it is).  The Canon support people looked at the problem and the
final response was that "Canon printers are not supported on Linux".
However, there is one guy who has persevered with this and has a
script that will install Canon printers on Debian:

http://radu.cotescu.com/how-to-install-canon-lbp-printers-in-ubuntu/

(Thank you Radu!).  I have verified this for, at least, a Canon
LBP7200C on Debian Lenny and Squeeze.

Agreed about HP.  Once upon a time, their engineering and support was
first-rate, but the modern printers don't match up - there's a lot
better out there.  I had a HP2605dn (colour laser) and only the most
expensive HP toner cartridges worked in it, and they invariably left
around 10% of the toner in the cartridge at failure point.  The design
of the printer is such that dust falls on to the mirrors in the
(Canon!) printing engine and the whole thing has to be dismantled to
clean them - a half-day job for the experienced.  Never again HP!

After I made a post, I phoned Samsung support, just out of curiosity.  
As normal, I faced up a girl from the 1st line support. Yes, she was not

The difference between Brother and Samsung customer support was 
impressive even on this level. I might be wrong, but after such 
experience I would expect to find the same difference on the upper as 
well.

Shame on Brother. I guess this takes their puppy out of my list. Not that 
I really needed their support (except drivers) or counted on it. But I 
get suspicious about quality of the printer itself now. This is how it 
works. :-)

I currently have All-in-One HP OfficeJet 6310. It is my first HP 
printer and probably the last one. I do not like neither the company nor 
their printers. They capitalize on their former reputation for quality. 
But the reality is, their printers today are flimsy, of low specs, and 
over priced, as well as over priced is their supply line. Lately HP seems 
to be mostly concerned of how to prevent their customers to use third 
party supplies. In this they did achieve real heights.

I mostly agree that support for Linux is probably the best due to efforts 
of HPLIP project folks (or it is just one guy?). The driver is very good. 
I print, scan, and fax without any problem. And it has quite nice GUI 
interface too.

Except one thing - manual duplex. The way it makes it is still 
incomprehensible for me. It's not enough that I have to turn manually the 
entire stack in a certain direction, but at the first print out it turns 
each even page in the direction opposite to each odd page. Thus I have 
first to go through the entire stack and turn evens and odds at one 
direction and only after this I turn the entire stack as suggested. Boy, 
I'm even having hard time to describe it now.

I reported it as a bug and never since heard from them, as well as never 
since I tried to use manual duplex with my printer.

Thanks for your suggestions.

Not sure about best practices, I like staying with stable and will use Debian 
backports.  No longer a proponent of apt pinning sid & testing, or other repo's.

Iceweasel (Firefox) 5.x entered Sid recently.  I think once it migrates to 
testing, it will be a candidate for squeeze-backports.

I have squeeze-backports added to my sources.list & /etc/apt/preferences files.

I've recently been made aware of some of the benefits of the Chrome /
Chromium and Firefox.

Running Squeeze, the most recent Chromium release is from May 13, and
Firefox 5 isn't available either.

I'd like to manage either / both from my package repos, but be
reasonably current.

What's best practices?  Method or pointer to docs appreciated.

Thanks.

Well, both of them listed as Perfectly Working, but submitted by user and 
not verified. The OS/distro and its version is not indicated. I've tried 
to use Download .ppd file link. It failed with "servers error" several 
times.

It wasn't much in help, I'd say.

Brother HL-2270DW - PCL6
Samsung ML-2855ND - PostScript3, PCL6, and PCL5e.

Samsung provides an executable installer but I read a .ppd file is

deeply but can be extracted.

Brother I'm not sure, yet

Re: Debian 7 'Wheezy' to introduce multiarch support

2011-07-26 Thread Jerome BENOIT

Hello List:

I have a very naive question regarding the "multiarch" transition:
will the upgrade of Debian box from Squeeze to Wheezy be messy ? or as smooth 
as previous upgrades ?

Debian 7 'Wheezy' to introduce multiarch support

During this years annual Debian Conference DebConf11 made the
introduction of "multiarch support" a release goal for the coming
Debian release 7 "Wheezy" to be released in 2013. Multiarch is a
radical rethinking of the filesystem hierarchy with respect to library
and header paths, to make programs and libraries of different hardware
architectures easily installable in parallel on the very same system.

"Multiarch is a major enhancement to Debian's ability to deliver on
the promise of being a universal operating system" explains Steve
Langasek, driving force of the implementation, "not only will it make
crossbuilding easier, but also enables better support for legacy
32-bit applications on new 64-bit installations and in the future will
even allow live migrations from 32-bit to 64-bit systems."

People interested in the topic can watch the talk by Steve Langasek
"Multiarch in Debian: 6 months (or 6 years) on" today at 16:00 CEST
(14:00 UTC) by using the DebConf web frontend at
http://debconf11.debconf.org/watch.xhtml.

I'm looking to buy one of these B/W Laser printers:

I have no personal experience with printers of these manufacturers and

I've never used a Samsung printer, but their support for phones, hard
drives, and other electronics has been very good.
Brother support is horrible. Their products used to be good, but now
they're awful (just like Dell).


Brother have a driver for the above particular printer. But on their
"Evaluated Distributions" page lists only Debian 5.04 32 bit, while I'm
using Debian 6.02 64 bit.

As long as the kernel has dropped support for it, you should be okay.


It also lists Ubuntu 10.04 both 32 and 64 bit. This is fine but would it
work under the next release/s?

Same as above. Ubuntu, however, is much more user friendly in the sense
that it will download and install proprietary drivers as necessary. On my
Debian machine, I compile my own drivers for my unsuported hardware, not
hard at all if you don't mind searching the net for them.


The Brother customer rep shocked me by not being able even to pronounce
the word Linux, by not knowing what 32 bit is, and by asking at the end
of conversation:"How have you named your OS? Is it a special OS, what is
it?" This is exact quote.

Again, Brother support is horrible. I wouldn't expect them to be
engineers, but to at least have heard of Linux and know that is a kernel
not an OS :)


my priorities are:

- reliability of the driver in terms of its availability and OS support
after upgrade to the next OS version.
- reliability of the printer itself
- build-in duplex printing
- cost effectiveness
- I do not care much about wireless, but if it comes, it comes. :-)

If you can suggest any better printer that I've picked up, please, do.



I've had an HP LaserJet p1102w for almost two years now. I've used it with
Lenny, then Squeeze, and now Wheezy with no problems. Even the wireless
printing works. No duplexing, unless you count manual :) IMHO, HP has the
best support for Linux when it comes to printers

help to choose right printer to buy

2011-07-26 Thread Juan R. de Silva
I'm looking to buy one of these B/W Laser printers:

Samsung ML-2855ND or Brother HL-2270DW.

I have no personal experience with printers of these manufacturers and 
have no idea how good their drivers/support are.

Samsung lists as supported only few distributions of old versions and 
offers so called Universal Pint Driver, about which I've read quite 
controversial things.

Brother have a driver for the above particular printer. But on their 
"Evaluated Distributions" page lists only Debian 5.04 32 bit, while I'm 
using Debian 6.02 64 bit. 

It also lists Ubuntu 10.04 both 32 and 64 bit. This is fine but would it 
work under the next release/s?

the word Linux, by not knowing what 32 bit is, and by asking at the end 
of conversation:"How have you named your OS? Is it a special OS, what is 
it?" This is exact quote.

If somebody uses one of the printers above, or has a general experience 
with printers of either of the companies and can share it with me, here 
are my questions:

1. Does one of the above printers work under Debian 6.02
1. On which company driver/support (support ? :->) is better to rely?
2. Which of the 2 printers above is a better choice, considering my 
priorities are:

- reliability of the driver in terms of its availability and OS support 
after upgrade to the next OS version.
- reliability of the printer itself
- build-in duplex printing
- cost effectiveness
- I do not care much about wireless, but if it comes, it comes. :-)

If you can suggest any better printer that I've picked up, please, do.

VirtualBox: sharing files between the host and guest OS

2011-07-26 Thread Jason Hsu
How do I share files between the host OS and guest OS?  (Both are Linux.)

The version of VirtualBox I'm using is 4.0.8 r71778.

Until recently, I was using an older version of VirtualBox and had no 
difficulty sharing files between the host and guest OS. In VirtualBox 4.0, I 
have yet to successfully do so.

The directory I'm sharing is ~/share under the guest OS and /mnt/host under the 
host OS. When I enter "mount -t vboxsf share /mnt/host", I get the error 
message "/sbin/mount.vboxsf: mounting failed with the error: Invalid argument".

The package dkms is already installed in the guest OS. I also installed the 
build-essential package in the guest OS, but the file sharing still refuses to 
work.

Yes, I have the shared folders set up under the Devices -> Shared Folders menu. 
And both the ~/share folder in the guest OS and /mnt/host in the guest OS exist.

So what little detail am I missing?

It sure seems to be present out of the box on mine (Lenny and Squeeze). 
In addition to the browser export setting, I source my .bash_aliases

Gnome has to be launched manually? Not my experience. On my distros it

That's strange because when I put BROWSER=/usr/bin/firefox && export
BROWSER in my .bashrc it over rode the sensible-browser entry in
/etc/mailcap (I don't use a ~/.mailcap file).

It is hard to argue about the old IBM 1403, a classic line printer.
But just the same those types of chain impact printers were pretty
expensive and weren't everywhere.  My memory is vague on the causality
of each since they were created before I was born.  :-) But I did
routinely use them at the university data center while programming on
the Honeywell and Harris machines using the qed editor on printing
tractor feed paper terminals.  The annoying back and forth head
movement of those is what motivated me to learn to type quickly so
that I could get the next letter onto the paper before the head
retracted, making the just printed character visible.  You see the
timing of the head motion was really quite annoying and if you typed a
little slow then it would bang back and forth and the feedback to the
brain was killer.  But if you could type the next character before the
head retracted then it wasn't so bad.

Yes. Dropping it there had no effect, until I explicitly added the
filename to ca-certificates.conf. Then, it had the same effect as
adding it to /usr/local (I actually went that route before RTFM, as a
good admin should :)

To make matters more interesting, it would appear that fetchmail
accepts the certificate even though openssl still complains that it is
unable to verify the signature. I've now done the same test with
gmail's service, and I get roughly the same result:


$ openssl s_client -connect pop.gmail.com:995 -showcerts
CONNECTED(0003)
depth=1 /C=US/O=Google Inc/CN=Google Internet Authority
verify error:num=20:unable to get local issuer certificate
verify return:0

$ openssl s_client -connect pop.gmail.com:995 -showcerts
-CApath /etc/ssl/certs CONNECTED(0003)
depth=2 /C=US/O=Equifax/OU=Equifax Secure Certificate Authority
verify return:1
depth=1 /C=US/O=Google Inc/CN=Google Internet Authority
verify return:1
depth=0 /C=US/ST=California/L=Mountain View/O=Google
Inc/CN=pop.gmail.com verify return:1


So I guess the original question is solved, "put the certificate
in /usr/local/share/ca-certificates" is really the correct solution.
But then there are two more questions open:
- why does openssl respond differently when I specify a CApath that
should be the system default?
- what is the correct way to check whether a ca-certificate is
installed correctly?

Arno

Yes.  Note that I did say that its history is interesting.  :-) It is
why there is both backspace and delete on the keyboard.  So that you
can backspace to the characters you want to delete and then you can
delete them.  But that meant that when 0x7f characters encountered on
input were ignored since they were characters that had been deleted.

Printable on paper tape, yes, but if you loaded the paper tape back
into the system then you found that the deleted characters had
disappeared. :-)

A fun trip down memory lane...  And in the play of semantics.

This is expected due to the fine grained control exposed in bash.
In the bash man page you will find:

   ~/.bash_profile
  The personal initialization file, executed for login shells
   ~/.bashrc
  The individual per-interactive-shell startup file

A very typical thing to do in the ~/.bash_profile is to source the
$HOME/.bashrc file with a snippet similar to the following:

  if [ -f "$HOME/.bashrc" ]; then
. "$HOME/.bashrc"
  fi

Or this following in ~/.profile which needs to be shell portable:

  if [ -n "$BASH_VERSION" ]; then
# include .bashrc if it exists
if [ -f "$HOME/.bashrc" ]; then
  . "$HOME/.bashrc"
fi
  fi

P.S. I am also using fvwm, right now in fact.

Wow, I just spent the last five minutes laughing.  Even though I don't
feel this is the most productive way to ask for assistance, I must
confess to being able to relate to it due to having felt similar
frustration in the past.

In trying myself to find an answer to how to get an iso for a
usb-stick, I found it was a bit of a maze.  From many of the links on
the issue, I was led to this:
http://ftp.nl.debian.org/debian/dists/squeeze/main/installer-i386/current/images/netboot/mini.iso


(snip)


Anyway, seems confusing to me, too.  Given that some usb-sticks can
store even more material than a dvd, and given that usb-sticks are
commonly the only removable drives on a lot of computer devices today
(IE, laptops), why the links for installing Debian group usb-sticks as
"other images (netboot, usb stick, floppy, etc)", rather than having a
specific entry for it as they do for cdrom, dvd, and even blu-ray, is a
mystery.

So, can the netinst-cdrom image be used with a usb-stick?  And if so,
why the different listing for usb-sticks?  And if not, why not?


I don't know why the different listings exist. Maybe this part of the 
Debian site could do with a partial rewrite.


The Wheezy netinst-cdrom image can certainly be used with a USB stick 
(and a USB hard disk too). I've successfully used this method to install 
a number of test systems recently.

That's interesting.  A while back, when I tossed out gnome and gdm in
favour of fluxbox and startx, I likely also removed automatic mounting
processes in my computer.  So, I had to set up stuff to manually mount
things, which resulted in the fstab entries I used to have.  That
having changed in Squeeze has caused some issues -- IE, it seems the
labelling of all drives became different.  Anyway, to avoid having to
look up the specific UUID each time I insert a new device, it may be
useful for me to look into setting up some sort of automatic mounting
utility (like installing pmount, maybe).

Cool, you should be prepared then.  I'd use menuconfig.  Under
"Processor type and features":

Select Symmetric multi-processing support
Select Processor Family-->Pentium-4/Celeron...
Set Maximum # of CPUs to 2
Select SMT (HyperThreading) scheduler support
Set High Memory Support to OFF or 4GB, but not to 64GB
Unselect Multi-core scheduler support
Unselect PAE

There may be other options you need to tweak here and in other config
areas.  For example you'll probably want to enable lodable module
support, and to build your SATA and ethernet drivers into the kernel.
Personally I build everything I need into my kernels and nothing I don't
need, and I disable loadable module support unless I need iptables
support on a particular box.  I don't use initramfs.  I only use Linux
on headless servers, so I omit things like USB support, and I disable
power management.  I only build in filesystems I will use, which are
ext2 and XFS, ext2 for /boot and the root filesystem, XFS for everything
else.  I build the firmware blob in.  Etc, etc.

check the installation media and booting parts of the installation
manual to see which method fits u the best.

for usb stick booting and installing, it's a one-liner as documented
in the manual[1]
run the command below with root permission.

$cat /path/to/your/debian-stable-amd64-i386-netinst.iso > /dev/sdX

replace /dev/sdX with the path to ur usb device.
make sure that u backup the whole disk, since the partition table will
be overwritten.

if u don't feel comfortable with `cat', use

$dd if=/path/to/image.iso of=/dev/sdX

btw, if u already have *nix installed on the target machine, no
external media is required for installing debian.
fetch the iso file and Grub/Lilo boot files, add the menu entry for ur
bootloader, reboot and you'll see the debian installation interface.
see the manual[2] for details.

debian iso images have native usb stick support.
what u want is a one-liner.
and i won't explain too much to u, in case u get lost in a desert of

backup ur files on the usb stick, then run

What is the nature of the bottleneck, IOPS or throughput?  What is the

Yes.  Identify the workload and required storage space.

LSI/3ware are very good.  I hear the higher quality/price Adaptec cards
are decent as well.  Drivers for all above are in the kernel source
tree.  Steer clear of Areca cards, and steer clear of all fakeraid
cards.  If it doesn't have onboard memory it's a fakeraid card.

I'm going to make a couple of educated guesses before awaiting your
response.  You're currently running 2 mdadm or LVM mirrored disks in
each server, and experiencing an IO bottleneck.  Thus the servers are
likely MTAs in an MX farm.  If so, your bottleneck is insufficient head
seek bandwidth while random writing incoming mail files to the queue
directory.

The best way to solve this problem is running a couple of properly sized
SLC SSDs in an mdadm mirror pair.  Your IOPS will jump from the
~150-300/second you have now with 7.2k or 15k RPM drives, to between
3,000 and 30,000, far exceeding any future need.  Side benefits are
reduced power draw and noise.  A suitable SSD would likely be the Intel
SSD 311:  http://www.intel.com/design/flash/nand/311series/overview.htm

If you'd rather go the mechanical route:
http://www.lsi.com/products/storagecomponents/Pages/MegaRAIDSAS9260CV-4i.aspx
 Includes 512MB flash backed write cache, no BBU required.

Quantity 4

A quality 4 bay 2.5" SAS/SATA hot swap cage that occupies a single 5.25"
bay, w/2 integrated cooling fans:  http://www.icydock.com/goods.php?id=114

As always, disable the individual drive caches in the controller BIOS
and enable the card's 512MB write cache.  Balance the RAID cache for
equal read/write as files written to the MX queue are typically
immediately read back then delivered to a mailbox server.  Configure the
4 drives as RAID10 with the smallest possible stripe size because mail
files typically average less than 32KB in size.  If the controller
offers an 8KB stripe size select it, if not select the smallest offered.
 This will help minimize wasted space due to partial stripe width
writes, and will slightly increase performance.  Due to the 512MB of
RAID cache your queue IOPS will be in the multiple thousands, vs only
600 for the 2 spindle stripe.

Mirrored SSDs will have orders of magnitude greater IOPS and will be
cheaper vs the RAID card/mechanical drive solution, but will have far
less space.  Using larger SSDs drives the cost up quickly.

Install an addon like User Agent Switcher or something like that so you 
can change your user agent string to say firefox.  Or go to
mozilla.debian.net for more updated iceweasel packages.  You could also 
run the FF binary from Mozilla right out of your home directory without
affecting your system install.

Lenny is old stable so you'll stop getting security updates in less than 
a year.  You may want to plan an upgrade to squeeze in the near future.

This isn't about having access to the files at all.  It's about keeping
them, and the best thing to do that is to send them to myself by email.

The times when a 10 or 100MB file was too large to fit on your hard disk
are long gone --- or are you still using hardware that old?

Eventually, yes --- and to be able to do that, I want to keep the
logfiles.  There's no problem with files that are several gigabytes in
size.  You can grep or view them just fine.

You you would have to check the logfiles constantly to avoid surprises.
They can be written to pretty fast.  I don't want to spend all day
watching logfiles.  Running logrotate every minute or so isn't a good
solution, either.

> There is also the idea of using a syslog server that is more easily

That can be a good idea when you want to access logfiles stored
remotely.  The ones I have, I just need them sent to me by email.

In about:config, I have a setting for
'general.useragent.extra.firefox', the value of which I set to
'Firefox/4.0' (I'm using the 4.0 version of Iceweasel).  Perhaps that
setting would help?

Change Iceweasel identification

2011-07-26 Thread mark
HI,

I'm running Lenny with Iceweasel 3.0.6. I understand that I can't 
upgrade the browser without upgrading to sid, which I'm not willing 
to do at this time.

Problem that I am having is that when I access yahoo mail, it tells me 
that in order to use the new version of yahoo mail, I have to use 
firefox (there are some other choices, but I don't want to install 
another browser).  

How can I have sites identify iceweasel 3.0.6 as firefox so that I can 
access the features of sites that are blocked from me?

thanks,

Mark

After I noticed unison had problems with this file, I took another
file, about the same size, in other directory, and did the rsync and
scp experiments with those files. So I don't think it is a problem
with that particular file or disk sector. But I will check your other
suggestions as soon as I can.

Indeed, this is very frustrating, 20M is not a huge file, but it's the
size which is giving me trouble (ok, it could be less, haven't tried,

I thought exactly the same thing, that's why I tried scp after rsync.
One of the machines reports this:

df -h
FilesystemSize  Used Avail Use% Mounted on
/dev/sda1 178G  146G   24G  87% /
tmpfs1007M 0 1007M   0% /lib/init/rw
udev 1002M  172K 1002M   1% /dev
tmpfs1007M 0 1007M   0% /dev/shm

This is the remote machine I'm trying to synchronize with every night.
I will check at home the other one when I can.

What happens if you try to copy this file locally or on some other
device or force reading it with, for example, dd (dd
if=/path/to/yourfile of=/dev/null). Maybe the storage device on which
it is located has some bad blocks. You could also try to run scp
within strace to see where or what hangs.

Is only this one file the problem or maybe other files as well? What
happens if you copy (not move!) that file to another location on your
drive and then try to scp it over? Is the content of the file thus
that you could send it via plain netcat? If so, did you try something
along the lines of:

destination# nc -l yourport | md5sum

source# dd if=/path/to/mysterious/file | nc otherhost.example.org yourport

Please note that I have not tested the commands given here, so you
might want to have a look at the manpages to make sure you got them correct.

Mm, it's a pity, because unison is such a nice program. But if

Hi. I posted an update on this today. Now I don't think it's a problem
with unison, as I detected one particular file which was giving
trouble, but it seems I actually have a problem with large files (20M
is enough to hang it). Which does not make me happy anyway.

I should clarify that I am doing all of this from command lines under a
window manager (fvwm).  When I call startx, the first xterm's settings come
from ~/.bash_login.  But if I call more xterms from there, any settings in
~/.bashrc override those.  This was easily verified by playing with the login
prompt (PS1).

Assume I have no text/html entry in ~/.mailcap and no BROWSER defined in my
settings (as verified by "echo $BROWSER").  If I then call metamail, it calls
sensible-browser, which in turns calls x-www-browser.  I don't know where
that is defined; it's not in /etc/mailcap.  If I define BROWSER as iceweasel
in ~/.bash_login, and then call metamail from any xterm, then sensible-
browser calls iceweasel.  If I only define BROWSER in ~/.bashrc, this doesn't
happen for the first xterm but does from subsequent ones.  In any case, there
are six processes:

26091 26012  metamail z

Linux RAID for Perfomance and supported Card

2011-07-26 Thread Siju George
Hi,

A few of my servers are running on Linux Software RAID 1 and is
meeting disk I/O bottle Neck.
I am considering other RAID Levels to increase Performance as well as
keep the Redundancy.

I guess I should Go for Hardware RAID 10 as per my colleague's advise
after reading through many reviews on the Internet.
Does any body have any ideas or Suggestions?

Also which RAID card is most supported on Linux?

Thanks

Looks promising, Christoph.  But it appears to be all in German,
even when I click on the UK flag.  After all, this is the English
list (debian-user).  And I don't like advertising on Debian sites,
even unofficial ones.  After all, Debian is a non-profit organization.
(That's why its URL ends in ".org" instead of ".com").

Re: Transfering large files (was: Unison hangs on copy)

I'm somewhat surprised, because when I was thinking of large files, I 
was thinking of CD image size files.  (I used to transfer these over a 
33 kbps modem, requiring about 65 hours per image, spread out over 
(typically) 5 nights.  Oh, the good old days ;-)

I don't really have any good thoughts to offer.  I'd be looking to make 
sure that no temporary storage areas have been filled (presumably /tmp 
on either machine), in fact, I'd probably do a df for all partitions on 
both machines and make sure all of them have plenty of space (a nice 
big multiple of 23 MB--I don't really know how much storage rsync, or 
scp need, but I'm just "grasping at straws" looking for possibilities.

While rsync may do some thinking (i.e., pause) during a 23 MB file 
transfer, I don't think scp would, but there still might be something 
that is timing out. 

All from me is just random speculation, however.  Good luck--I hope 
someone else will have some better suggestions for you.

Ummm, earlier printers than that didn't have moveable heads like that. There
was this printer that used a chain with a few sets of letters and 80
hammers. When the right letter moved under the proper hammer, it fired (and
if you asked it to print a row with letters in the 'right' order, the chain
would snap). Point being, a 'head' didn't move to create a space, so that
logic is flawed.

I also don't think space is printable but whatever.

Space is a printable character.  The C isprint(3) function says:

#include 
#include 
#include 

int main() {
  char upper = 'a', lower = 'a';
  for(; upper < CHAR_MAX && isprint(upper + 1); ++upper);
  for(; lower > CHAR_MIN && isprint(lower - 1); --lower);
  printf("lower: %d, upper: %d\n", lower, upper);
  return 0;
}

output:

lower: 32, upper: 126

I don't believe CONFIG_X86_PAE is the cause of Frank's problem.  I
believe it lies in two or more other config options.  It just happens
that he's using a pre-compiled canned Debian kernel that seems to have
other features turned on that are causing his problem.  See below.

I don't believe so.  I doubt Frank is the only person on the planet
using a Northwood C series uni-core Pentium with HyperThreading hardware
and CONFIG_X86_PAE enabled.  He may be one of the few attempting to use
a canned kernel with PAE, SMP, and multi-core enabled in his kernel, on
a CPU that only supports 1 of the 3.

The answer is very simple.  Intel engineered its HT circuitry in a way
that standard SMP code will see two CPUs instead of one.  The code that
is enabled by CONFIG_X86_HT=y wasn't written until after these HT CPUs
hit the market.  Linux with standard SMP support worked fine on such
uni-socket HT CPUs.  But, for obvious reasons, the standard SMP
scheduler did not perform well in this scenario.  The CONFIG_X86_HT=y
code does proper scheduling on HT CPUs.

As I mentioned it is a single core CPU, 8 years old at that.

He does, as I mentioned above and in my addendum to his Debian bug
report.  I don't believe Frank is hitting a Linux kernel bug, or a
Debian bug.  I simply believe he's using the wrong canned kernel for his
Northwood C Pentium IV.  If this is the only Debian x86 kernel going
forward, then Frank should simply forgo using HT, or roll his own kernel.

For close to a decade I've been rolling my own kernels from vanilla
source to avoid problems such as this, and for other reasons.  Given
that Frank didn't know he had an HT, but not dual core, CPU, and has
probably never heard of CONFIG_X86_SMP or CONFIG_X86_HT, he's probably
not a candidate for rolling his own kernels. :(

More than 150 up-to-date Debian howtos & tutorials online (server, virtualization, etc)

2011-07-26 Thread Christoph Pilka
Hi folks,

in the last months I've published more than 150 Debian howtos which
are online now at  http://www.asconix.com/howtos/debian

The howtos are covering the following topics so far:

* Debian as infrastructure (BIND, Samba ...)
* Webservers (Apache2, Nginx, Lighttpd ...)
* Databases (MySQL, PostgreSQL, CouchDB, Redis, ...)
* CMS's (Plone, Drupal, ...)
* Virtualization (Xen, VMware ESX ...)
* Backup (Bacula, rsync ...)
* E-Mail & Groupware (Postfix, Dovecot, OpenXchange, Zarafa ...)
* VoIP (Asterisk, Gemeinschaft ...)
* E-Commerce (Magento, OXID VirtueMart ...)
* Media (XBMC, MediaTomb, Coherence, Fuppes ...)
* Desktop Environments & Window Managers (XFCE, Awesome, XMonad,
StumpWM ...)
* Development (Ruby on Rails, Java, Lua ...)

... and so much more ;-) Few of the howtos are translated, the non-
translated are self-explanatory (I hope so ;-)). And if anyone of you
has time and fun to work on this documentation project, please let me
know. I've some further drafts in my pipeline for the next few weeks
(e.g. Hadoop & Cassandra, Dropbox clone, High Availability etc.). So
stay tuned and please leave comments at the bottom of the howtos.

Cheerio,
Chris
