Re: PowerPC install stuck at dmesg

[Michael Aldridge]

gave it another try this evening, and for no apparent reason, it booted up
to a much furthur place, still not an install, but past memory allocations.
 It had a line that said cut here
followed by a slew of messages, some of which began with 'kernel bug' and a
memory dump.  I attempted to take a picture, but the machine had already
reset by the time I had found a camera.  I am attempting to duplicate that
result now.

If you were to forgo tape as an option, I could recommend luckybackup
(it's in the current Squeeze repos).

I stumbled across it after I found when upgrading to Fedora 17,
mondoarchive no longer worked so that left me looking for something else
to use for local backups (I use rsync for remote ones) on Fedora.

It's basically a frontend for rsync that does incremental backups,
snapshots, etc & it really is more than adequate. I've checked the
restore function & that worked fine, so all in all it does the job that
I ask of it very well. YMMV.

Cheers,

What does stty's iutf8 actually do (effect)?

[Dan B.]

The manual page for stty says that the input setting "iutf8" controls
whether to "assume [that] input characters are UTF-8 encoded."

What does setting actually do?

(I understand UTF-8 and its mapping between byte sequences and characters.
What I don't know is where character decoding and encoding are done in
Linux input and output components (virtual consoles, xterm/etc., tty
devices).)

What does that iutf8 setting actually affect?

Is the terminal (tty?) driver involved in decoding the input byte stream
into characters for the process attached to the tty device?

Or does the driver decode bytes into characters only for its own
checking for special characters (e.g., for stty intf CHAR)?

Thanks,
Daniel

the point of reaver is to show you why wps is *bad* - disable it if

as far as security goes. if you don't like psk stuff, setup radius or

You're correct about not compressing the data. Uncompressed tars are

Thierry, I don't have windows in this machine, neither internet

After googling and researching I'm still in the dark. It looks like
this is the way to go. But I never used it before. Is it like a "PAM"
module that you set up in some config file?

This site tells a lot about configuration, but nothing about WPS or QSS.
http://www.thinkwiki.org/wiki/How_to_install_wpa_supplicant
When using wpa_supplicant, the examples need a passphrase or password.

The man page also does not help:
http://linux.die.net/man/5/wpa_supplicant.conf

This site explains some config files in detail, but I still cant
figure out how to make this thing work.

I bet it is not that hard. After all, it is a quick setup! :)

After trying wpa_cli, I could find a PBC push button! It connected my

FWIW, I gave up backing up to DVD when my data reached about 1/10 of the
size of yours. Too slow, too cumbersome (having to change disks), too
unreliable, to expensive etc.

I suggest to buy one or better two other 1TB usb disks and backup to
them (alternately). You don't need to be a shell programmer, a simple
$ rsync -av /path/to/disk /path/to/backup
followed by
$ cp -al /path/to/backup /path/to/backup-
where  could be a number or a date, should be more efficient (and
cheaper in the long run) than a pile of optical disks.

Occasionally, you could use rsync's -c option to verify that your backup
is ok.

(/path/to/disk is the mount point of your existing disk; /path/to/backup
is mountpoint and path of your backup disk)

My 2ct,

Johannes

Long delay when shorewall/shorewall6 starts/stops

[Nate Bargmann]

This has bugged me on and off most of this year since for some reason
that I can't find, the shorewall/shorewall6 startup scripts have a pause
of about a minute before the system start/shutdown can continue.  Right
now this affects both my desktop and laptop running Sid.

My desktop's network connection is a wired Ethernet that is managed by
the ifup/ifdown scripts.  My laptop's wireless and wired interfaces
are managed by WiCD.

Right now in /etc/default/shorewall|shorewall6 is the variable
'wait_interface' that is undefined.  A bit of testing shows the delay in
the scripts is not related to this variable.  After this I am stumped as
the delay is deeper in Shorewall itself.  This has gotten annoying
enough that I'm seriously considering a firewall alternative.  I like
Shorewall as it is relatively easy to configure for new servers and
such.

Depending on your data, compression may or may not be useful. Video 
and audio data is usually already optimally compressed.


4.5G on a DVD is also not terribly useful if you want to back up 
large amounts of data. BluRay writers are cheap enough these days, 
and BD-RE discs are not too expensive. BD-R discs are even cheaper 
for doing an archival backup.


You don't say what you are backing up. If it is the data on the 
external drive, you may want to consider getting a second drive and 
backing up to that. It's a lot easier than manually swapping discs. 
In this case, you could try Bacula. It's not too difficult to set up 
and quite flexible.



All the folders in my home folder (except "desktop") is a link to a 
folder on the backup drive.  These are: Backups, Documents, Downloads, 
Favorites, Memos, Music, MyPDA, Pictures, Programs, Projects, Public, 
Temp, Templates, Themes, Utilities & Videos. Also, I have the entire 
filesystem for this computer and for a separate Windows 7 computer 
copied in tar.gz format. (I connect the drive directly to the Windows 
box via the usb cable to do that.) There is also a separate "Backup" 
folder on the backup drive where I have a couple of programs running 
backups /home, /opt & /var and where I also back up cells phones for 
friends and relatives (8 at the moment) and things like my camera and 
Palm PDA SD cards.


(Speaking of tar.gz; what is a good format for compression for this 
varied type of info? I've access to about 20 different formats on this 
box.)


This is the type of stuff I want to make a safe backup of.  I've 
already lost all the info on the drive once several months back when 
someone defragged it when it was hooked up to the windows box. I have 
a ton of old CDs collected from about 10 years of use that I was able 
to (with a lot of pain and work) get quite a bit of data back from.


The suggestion of a blue ray drive and disk or a secondary drive sound 
like a good one.


Any other suggestions for things I haven't thought of?


Whether or not optical is a PITA depends on how much data you have to 
back up. If it fits onto a single disc, it's great. Otherwise you may 
want to look at other options. BluRay can hold 24G - 45G depending on 
the number of layers.


I haven't seen BD-RE in double layer yet, so assume 24G for now. For me, 
that's more than sufficient to back up all my work in a year. BD-RE is 
good for a long time, depending on usage, and is simple to use.


I prefer lzma compression for tars. It's a bit slower than some, but 
gives really good compression.


Never rely on a single backup. I keep multiple archives of old work on 
optical discs, in addition to a live copy and a live backup copy on a 
separate file system on the same RAID5 array. That's actually not all 
that safe (the RAID array could fail), but the live backup copy is 
mainly used if I accidentally delete the wrong file.


I don't recommend backing up entire file systems very often. It's your 
data, not the programs, that are critical. You may also want to back up 
/etc since it contains your system settings and is highly compressible.

I did not try this with your SVG graphics as I did not bother to extract
them from the XHTML source but you could probably try librsvg2-bin. The
command rsvg [source] [destination] easily converts SVG to PNG. I also
had some problems with convert's SVG rendering. It was too slow for my
300 MiB svg file and I found that rsvg did this much faster (and also
used a lot more RAM).

Lorenzo -

You may need to install an old version of a distro on your hardware "troppo 
obsoleto".  One of the problems is that modern distros no longer carry the 
old drivers that you obviously need.  When I first started using Linux, it 
prided itself on being backwards compatible, but sadly that is no longer the 
case.

I have isos of various old distros, so could let you have a few to try, if you 
like, if you cannot find anything that might be suitable.  They are mostly in 
English, though I think I have still got one or two German ones.

Incidentally, this is an English speaking list.  I would none-the-less have 
replied in Italian as well as English, but any knowledge I have of Italian is 
passive not active. :-(

There is an Italian Debian users list, which you might find more useful:

I stopped and started the Daemon anyway, but nothing changed.

The Services/Hosts didn't disappear from time to time, only the exact
same host is always shown with it services. The other two are missing,
but I can access their services any time without problems if I go to the
"Hosts" page (status.cgi?hostgroup=all&style=hostdetail).

It's like there is some kind of setting saying "Show only first host".
("Limit Results" is 100 per default but it doesn't matter if I set it to
a higher value.)

you can encrypt /boot as long as grub is aware of the schema iirc.
but, this begs the question - why? do you store your web cache in
/boot, or a db of your cc numbers, or your porn pics, or your kid's
birthday picture? or do you care that someone might recover that you
stored your kernel image on the second partition of the first disk?

i personally don't see the need for full disk encryption. i mean, if
you live in the US, a court order will keep you in jail or force you
to give up the password vs if you have smaller encrypted files that no
one finds (obfuscated in databases of pictures of a small encrypted
file or some such scheme) that someone might now find. or, if you surf
the net in a vm (as you should anyway) and encrypt the vm image, your
browser data is safe if someone steals your computer. fwiw

I really hate to be the old fogey here, but if you've got the $$, tape 
sure does a good job. Use Amanda for both incrementals and fulls, and to 
reduce PITA, get cron to run them overnight. Or over the weekend, if you 
want to backup a lot of data, but infrequently.

Optical disks and hard disks don't last. I have audio tapes from the 1950s 
that are still good. Tape has its disadvantages, but longevity isn't one 
of them...

For backup, though, I'd suggest springing a little more media and telling 
Amanda to write uncompressed tarballs -- for reliability and ease of recovery 
from a major disaster. You can recover from an Amanda backup tape with nothing 
more than plain old tar. A major PITA, but it's possible.

First, the bottleneck is going to be your hardware - laptop disks suck
(they don't spin as fast). Otoh, if this is SSD, you've got other issues to
consider. Ie, if the key is compromised, good luck wiping the data.

Second, what you're describing is a dev box (or more likely a playground).
Now, while it would've been cool if someone had built a formula one track
on my playground I think more toys in the sandbox would've given a better
bang foe the buck. What I'm saying is, who cares? I hear lvm has overhead
anyway, but maybe that's another matter. Maybe you should just go read
about all of the file systems and use the one that gives you the moat warm
and fuzzies. There's the long standing defacto ext, there's the wife
killer's reiser (also on sles iirc), there's the badly licensed zfs, the
old (but very good - made for six ~20 years ago) xfs.

So basically you are planning to use the system for a common desktop 
usage. Considering your hardware the filesystem would be almost 
irrelevant so I'd go for either ext3/4 which has more tools for 
recovering after a disaster and is well tested/supported.

There are some tools for the task. MondoMindi supports CD/DVD though is 
usually for cloning rather than backups. Then there are the usual GUI 
based tools such as dkopp, fwbackups, simple backup, kbackup, box 
backup... and backup2l, backup-manager or backupninja (command line) 
which seem to be specifically for CD/DVD although I would still prefer a 
simple tar script :-)

Sure

My laptop have i5 CPU with 3GB RAM.  I bought a new disk and want to create LVM 
on it, except /boot
And finally transfer all data to that DISK. So I am in search of a filesystem 
which can give me better
performance. The system will have apache+mysql+postfix as well as the desktop 
system KDE.

If you already discarded a problem from the configuration file, I would 
try to stop and then start the service to ensure there's only one 
instance up and running. I say this because I've read some reports from 
users experiencing this problem of hosts/services not showing up when

Yes, I need a file-system for LVM and that's why searching the best combination.
So gar I found at net that ext4 is good for lvm.

The suggestion of a blue ray drive and disk or a secondary drive sound
like a good one.


Hi Emil,

if you choose a second hard drive maybe you want to take a look at 
rsnapshot. It doesn't do compression, but it can also save you a lot of 
space if you want to keep several backups (keeping data for several days 
on a daily backup basis for example). rsnapshot uses hardlinks so that 
files that didn't change aren't saved again but every backup looks like 
a full backup.


Example:

452G/backup/daily.0/
18G /backup/daily.1/
534M/backup/daily.2/
534M/backup/daily.3/
532M/backup/daily.4/
446M/backup/daily.5/
444M/backup/daily.6/
471Gtotal

daily.0 is a full backup from today. daily.1 contains changed files from 
yesterday, daily.2 the files from the day before yesterday, and so on. 
So I can go back 7 days without having to backup 450GB each day.


So you don't have to clean up your backup by hand but still there is 
some time to notice that some files gone lost on your machine.


Bye.

A quick note about this. 

I don't recall what debian flavour you're running but if you finally 
decide to give these applications a chance, ensure you install the latest 
available versions (wheezy/sid should be fine but squeze may include an 
old release; if that's the case, the upstream project usually provide 
updated precompiled packages for many distributions).

Can't comment on the packages themselves, sorry, I never used Lazarus/
Freepascal before but this is what users recommend as a replacement for 
TurboPascal.

Consider installing that big amount of data in a virtual machine instead 
filling up your disk in a very insane way because if you finally don't 
like it, it's easier to delete a VM than having to remove those 
packages ;-)

You will have to "unsusbscribe" for one (normal) and then "subscribe" for

We have been using LVM with ext4 for a variety of workloads (webservers,
fileservers and mailservers) for quite some time, without performance problems.
As others have said, the performance depends most on the workload you will
use than in the "best filesystem".

Mmm... be very cautelous when installing packages from external sources.

I wonder what's the deal in getting the file from Oracle site¹ and 
follow the installation instructions. The only problem can be when 
using a 64 bits OS or browser, otherwise there shouldn't be any 
issue.

Can't tell, but it should be bundled with the package.

:-)

The  tag is mainly used to load another kind of content (java 
applets, multimedia files and all kind of external/non native "plugins", 
in general).

A good source for getting the basics on html and related technologies is 
this site:

Yes, SVG is not well supported in many Internet Explorer versions, for

You're welcome.

Note there's a slight difference when using  and  tags. 
Look, if you open the page:

http://members.shaw.ca/peasthope/Category2.html#Product0x0Test0

Rigth-click over the image and choose "view image info", there's no 
preliminary view, it appears to be broken. This can be good (to avoid 
being scanned by bots) or bad (the web browser cannot cache the source).

I'd go that way.

Another possibilities would be a/ using "hp-toolbox", select the desired 
printer and remove it, b/ using the desktop environment default printer 
applet (if any) or c/ by command line (e.g., "lpadmin -x printer").

Yes, but that's usually a problem coming from the programming side, not

Yes, but the OP already said he tried so but it failed (copy/paste from 
his first post):

The second point is what I think it failed but maybe is that the user did 
not try enough...

Are these videos also flashplayer based movies or different media files

Firefox has its own cache management system but the video you play 
locally is only limited by your system resources and given the specs on 
your computer this shouldn't be a problem. Anyway, you can check for your 
free space with "df -h".

The plugin's included in jre and jdk - if you don't see it in

The debian-way of adding this link is to place an entry called 
mozilla-javaplugin.so to /etc/alternatives :


sudo update-alternatives --install 
"/usr/lib/mozilla/plugins/mozilla-javaplugin.so" "mozilla-javaplugin.so" 
"/usr/lib/jvm/j2sdk1.6-oracle/jre/lib/i386/libnpjp2.so" 3


sudo update-alternatives --config mozilla-javaplugin.so

choose your weapon there if you got multiple solutions
after that consider testing java @ 
http://www.java.com/en/download/installed.jsp - it might complain java 7

Depending on your data, compression may or may not be useful. Video 
and audio data is usually already optimally compressed.


4.5G on a DVD is also not terribly useful if you want to back up large 
amounts of data. BluRay writers are cheap enough these days, and BD-RE 
discs are not too expensive. BD-R discs are even cheaper for doing an 
archival backup.


You don't say what you are backing up. If it is the data on the 
external drive, you may want to consider getting a second drive and 
backing up to that. It's a lot easier than manually swapping discs. In 
this case, you could try Bacula. It's not too difficult to set up and 
quite flexible.



All the folders in my home folder (except "desktop") is a link to a 
folder on the backup drive.  These are: Backups, Documents, Downloads, 
Favorites, Memos, Music, MyPDA, Pictures, Programs, Projects, Public, 
Temp, Templates, Themes, Utilities & Videos. Also, I have the entire 
filesystem for this computer and for a separate Windows 7 computer 
copied in tar.gz format. (I connect the drive directly to the Windows 
box via the usb cable to do that.) There is also a separate "Backup" 
folder on the backup drive where I have a couple of programs running 
backups /home, /opt & /var and where I also back up cells phones for 
friends and relatives (8 at the moment) and things like my camera and 
Palm PDA SD cards.


(Speaking of tar.gz; what is a good format for compression for this 
varied type of info? I've access to about 20 different formats on this box.)


This is the type of stuff I want to make a safe backup of.  I've already 
lost all the info on the drive once several months back when someone 
defragged it when it was hooked up to the windows box. I have a ton of 
old CDs collected from about 10 years of use that I was able to (with a 
lot of pain and work) get quite a bit of data back from.


The suggestion of a blue ray drive and disk or a secondary drive sound 
like a good one.


Any other suggestions for things I haven't thought of?

Is it? Last time I looked it wasn't. If wpa_supplicant handles it now,
then that's a lot easier. (Perhaps updating the apt summary might've

Informazioni per installazione Debian

[Lorenzo Tazzari]

Egr. Sigg.
vorrei installare Linux su una partizione di circa 2gb di un IBM ThinkPad
380XD.
E' un vecchio portatile, che, nella partizione principale, riesce a fare
girare Windows Millenium.
Vorrei sapere quale distribuzione Debian mi consigliate tenendo presente
che vorrei anche usare la porta USB a disposizione del PC per collegarvi
una chiavetta per la navigazione in internet.
La chiavetta viene riconosciuta da Windows Millenium ma il software che la
gestisce funziona solo su Windows Xp, Vista, o Linux.
Ho provato varie distribuzioni da Ubuntu, a Mandrake, a Damn Small, senza
successo.
Le installazioni si bloccavano per incompatibilità con l'hardware molto
probabilmente troppo obsoleto.

Grazie anticipatamente

Cordiali saluti

Lorenzo Tazzari

Why is a brute force attack program needed to use something which is

There is no useful answer to that question. The quality of a filesystem

on the way of encrypting a system, need some help please

[J. B]

Dear list,

I have bought a new HDD. Created 2 partitions.
An un-encrypted 1 GB /boot as a separate partition on the Disk.
And on the rest (2nd partition) an encrypted LVM with root and home as two 
logical volume on it.

Now I like to migrate my running system, the running "/" to the root of logical 
volume, but /boot
( which is actually a folder in my running system) should go to the  
unencrypted /boot of the new disk.
and the running "/home" to the home of logical volume. So that I can get my 
running system on the new encrypted
disk and can boot from there. Obviously I need to modify /etc/fstab and 
/boot/grub/grub.cfg on the
logical volume. How can I proceed ? Any suggestion will be life savior.

TIA.

Yes. From Debian Policy 7.5

If it wasn't for the Conflicts: statement in liboss4-salsa-asound2,
you could create a ‘real’ package libasound2 with a sufficiently high
version number using equivs. Then, you could adapt the control
statements of liboss4-salsa-asound2 to remove the Conflicts:
statement (doable, especially if you run stable and seldomly face
upgrades).

You could also try asking all the maintainers of the packages
depending on libasound2 to please use something like

| Depends: libasound2 (>= a.b) | liboss4-salsa-asound2 (>= c.d)

However, I doubt that this is a viable approach, since OSS is rather
deprecated on Linux (maybe the kFreeBSD folks would like such a
scheme, though) and there are _many_ packages which just depend on
libasound2. But, on the other hand, you could argue that some
packages already do this, for example, java-package, gimp or libao4
(check with apt-cache rdepends libasound2).

Best regards,

Claudius

Default is yes.


Warning: trying to mount an unzeroed logical volume can cause the
system to hang.

Versioned vs. unversioned dependecies

[Klaus Ethgen]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA512

Hello,

firs, please do cc to me as I have not subscribed this list.

I have the problem that I do not have alsa and will never have as it
never worked for me. It is instable, have poor sound ... However, on the
other hand oss4 is working very well for me.

Unfortunately, as sound tools uses /dev/dsp (oss api) in the past, more
and more applications only support alsa today. To make that workable
with oss one has to install the hack liboss4-salsa-asound2. This has a
conflict and a provide for libasound2.

But now it is not possible to deinstall libasound2 (well, it is and
everything except the package management work well without libasound2)
so it is not possible to use this package. The reason seams to be that
every package has a versioned dependency for libasound2 which seems not
to be working with provides.

Is there any way to have liboss4-salsa-asound2 installed on debian? And
is there any way to overwrite the versioned dependencies?

Regards
   Klaus

The generic term for this is "Wifi Protected Setup" or WPS. Support
isn't terribly well integrated into linux's wireless tools at the
moment, but you can install "reaver" (apt-get install reaver), which
should help you get connected.

I have read a link from above, yet can not find solution for
my two, now, problems - according to the links it just should work -
because of the new versions of kernel and ALSA:

. Voice redirection from mic. to speakers (they have mentioned on
simplification of SB circuits - and I believe it is my case - therefore
another mic. type is needed - do not know when - if ever - I obtain
one);

. Can not here my voice back from ekiga test numbers nor from the link
above that You gave. - For both calls I can hear sound but it seems
they do not hear me - though mic. volume meter of ekiga - changes as I
speak, so mic. probably works but either it is not send over network (I
checked my firewall and did not see relevelent droppings in my logs),
or ekiga does not get mic. signal - but as its meter reflects when I
speak, then I suppose it is wrong suggestion.

I guess ekiga people should make a diagnostic tool - that audio/net
problems might be inspected more accurate.


Sthu.

Depending on your data, compression may or may not be useful. Video and 
audio data is usually already optimally compressed.


4.5G on a DVD is also not terribly useful if you want to back up large 
amounts of data. BluRay writers are cheap enough these days, and BD-RE 
discs are not too expensive. BD-R discs are even cheaper for doing an 
archival backup.


You don't say what you are backing up. If it is the data on the external 
drive, you may want to consider getting a second drive and backing up to 
that. It's a lot easier than manually swapping discs. In this case, you 
could try Bacula. It's not too difficult to set up and quite flexible.

Nagios shows only one Host (Services)

[Denis Witt]

Hi,

after upgrade to Wheezy one of my Nagios installation shows only one (of 
three) hosts on "Services"-Page. On the "Hosts"-Page all three machines 
are listed and I can even go to the "Status-Detail"-Page.


Another Nagios instance works fine.

I've uploaded my config here: http://paste.debian.net/184146/

Any ideas?

Thanks!

iscsi debian. suggestion needed

[Muhammad Yousuf Khan]

Dear All,

i am looking into HA (or in other words to minimize restoration
process time) for virtualization in linux. i am using debian as a base
system KVM-Qemu as virtual environment. now i am exploring different
methods of HA. like DRBD, Rsync or ISCSI. so that if main server
hardware fails then other system would serve the purpose. with out
wasting my time in restoring backup.


so is there any one who is using linux ISCI SAN box for their
virtualization rather dell, or any other vendor.

so just wanted to know the pros and cons / stability / complexity .
since i am already dived into Linux so study wont be an issue.

and of course i know that LAN card can only give me around 1GB
throughput. but my data transmit is not that huge. we are a small
company with 25 nodes  and i think more or less 1 GB would be more
then enough.

any suggestion would be highly appreciated.

Thanks,

I'd be thoroughly inspecting the power circuits feeding those servers at
this point.  Do you have the machines set to automatically power back on
after power loss?  If you do, switch that mode so they stay off after AC
power loss.  That should confirm whether the problem is total loss of AC
voltage or a severely deep sag.

If the problem is a less severe sag, however, this test won't isolate
the problem.  For that you must dig into the UPS monitoring interface.
If you don't have a UPS, you'll have to put a tap on the AC circuit and
monitor the voltage.  This will require specialized equipment, as it
must be able to log the sag.  Some of the nicer Fluke meters can log the
lowest voltage, but probably can't tell you the time of day when the sag
occurs.  Thus, you'll need to highly trained electrician with the proper
equipment.

This could also be a thermal issue.  Do you have hardware monitoring
installed and properly configured?  The 'sensors' package?  Over temp
conditions will often cause random reboots.  Do the boxes have plenty of
zero restriction cool airflow?  Less than 25 Celsius intake air temperature?

The odds of having defective hardware in two HP servers causing random
reboots in both machines is extremely low, though possible.  If this is
the case it's a design flaw, not simply two defective parts.

It's also possible you have the wrong memory installed.  Can you provide
the specs on all DIMMs installed in both machines?  Did all of the
memory come preinstalled from HP?  Is it HP memory or aftermarket memory
from Kingston, Crucial, etc?

I guess no.

But, using a wired connection as in paragraph 3.1, 3.2, you should be able to 
use the QSS from the router thru your internet explorer as shown in 4.3 and 
later. Good luck!!!
