>So IMO this would only be useful for private use. i don`t think so - at least i wouldn`t say it`s only usefule for private use if you mean "home use" - think of developing countries where people cannot afford replacing their ram because of just "one bit out of millions" is bad - think of companies with large test/development environments which are not mission critical. we have many boxes out of service contract at work - and we still use them until they die or getting too old - think of a server which constantly crashes during a recover you try with grml - due to bad ram. should you really buy new ram for that machine if it gets replaced, anyway - and you just need it being running stable for the recovery process ? maybe this is just a theoretical scenario, but the discussion about the pro`s and con`s of badram patch is very controversial. anyway - i heard there will be an request for inclusion into mainline soon. roland > -----Ursprüngliche Nachricht----- > Von: Andreas Gredler <jimmy(a)grml.org> > Gesendet: 30.10.06 13:55:46 > An: grml(a)mur.at > Betreff: Re: [Grml] BadRam/BadMem Kernelpatch > On Sun, Oct 29, 2006 at 03:02:15PM +0100, devzero(a)web.de wrote: > > Description: > > > > BadRAM: Linux kernel support for broken RAM modules Summary: This page > > proposes an approach to support RAMs with defective addresses, This > > may open interesting business perspectives, where those RAMs can be > > sold under a white label for less money rather than discarded of > > without any profit. > > If you talk about business...

Starting domain name service bind failed
by T 01 Nov '06

01 Nov '06

Hi I used to use a caching only name server under Debian. When I start the same setting under grml, I get: % /etc/init.d/bind9 restart Stopping domain name service...: bindrndc: connection to remote host closed This may indicate that the remote server is using an older version of the command protocol, this host is not authorized to connect, or the key is invalid. failed! Starting domain name service...: bind failed! What could be wrong? Or, how to setup a caching only name server under grml? Thanks -- Tong (remove underscore(s) to reply) http://xpt.sourceforge.net/

Hello Liste Thank you for the advice I have decided to keep to "grml", so from now the installation will become cleaner and cleaner. What when 0.9 is in the pipeline and comes out? best regards Erich Minderlein

Remastering grml
by Juergen Fiedler 30 Oct '06

30 Oct '06

I think I got the basics of remastering grml down OK: I copy the contents of the squashfs to a writable folder, chroot into it, do whatever I have to do, leave, recompress the image copy it back and rebuild the ISO image. Works well enough. But: The resulting ISO image turns out much bigger than I anticipated. For example, I added a package that takes up about 1.5M on disk, but it increased the size of the ISO by about 14M. I mad sure to call 'apt-get clean' before leaving the chroot and to verify that /var/tmp and /root were empty and yet, there is space wasted that I can't account for. Can anyone give me any pointers as to what I can do to make sure that I don't add unnecessary ballast to my remastered ISO? Thanks, -juergen

BadRam/BadMem Kernelpatch
by devzero＠web.de 30 Oct '06

30 Oct '06

Hello ! Since grml seems to become more and more THE live-cd for admins, and maybe often being used for recovery purpose to save data from more or less "dead" boxes - did anybody think of taking a look at the BadRam Kernelpatch ? http://rick.vanrein.org/linux/badram/index.html --------------------------------------- Description: BadRAM: Linux kernel support for broken RAM modules Summary: This page proposes an approach to support RAMs with defective addresses, This may open interesting business perspectives, where those RAMs can be sold under a white label for less money rather than discarded of without any profit. Objective of the project My objective is to patch the Linux kernel in such a way that it can handle defective RAM modules. With defective RAM, I mean RAM which has some bits wrong at some (known) addresses. Normally, such RAM is considered useless and thrown away; the larger RAMs get, the higher the chances of failing addresses. With ever growing RAM sizes, it would therefore be pleasant to have an alternative to discarding of defective RAM chips. --------------------------------------- Unfortunately, I don`t have personal experience with this patch (yet), but maybe there are people on this list who know that patch already !? It exists for quite some time and a version for recent 2.6.18 kernel is available. Also, there exists a spin-off project "BadMem" at http://badmem.sourceforge.net/ something useful for GRML ? comments ? regards Roland ______________________________________________________________________ XXL-Speicher, PC-Virenschutz, Spartarife & mehr: Nur im WEB.DE Club!

mixing of distributions grml - unstable - testing - sarge for notebook
by Erich Minderlein 29 Oct '06

29 Oct '06

Hallo Liste For the user applications I would like to use as much as possible stable applications, also for a low update rate. (gnome desktop, gdm, evolution...) For the hardware I am forced to use up to date kernel drivers X server etc . I did not succeed up to now to resolve these dependencies. So I cannot use the notebook. Do I need dbus ? it is broken when installing gnome desktop environment. I definitely need udev, but it is also broken. other dependencies may show up when continuing So I cannot use the notebook up to now for user work. how to proceed. best regards -- Erich Minderlein <erminderlein(a)locoware.de> MARC Mannheim Rail Commerce GmbH

config id used in grml-rebuildfstab
by T 29 Oct '06

29 Oct '06

Hi Currently, grml-rebuildfstab executes '"rebuildfstab -v -r -u $fstabuser -g $fstabuser'" where $fstabuser is the user with the UID 1000. Is this UID 1000, GID 1000 configurable somewhere? thanks -- Tong (remove underscore(s) to reply) http://xpt.sourceforge.net/

Hallo When I install a regular debian sarge I am induced to enter a non root user to receive certain mails etc. This user has then uid 1000 gid 1000. Since converting old PCs to debian sarge now I own 3 (three) installations where this is my identity and I use it for my regular work. For a new notebook, which does not work with sarge, I choose to use grml, and have not yet come to the point of installing my user account. I have this for purposes like NIS and nfs and I use it for nfs. this habit should be taken into account An user like grml-rebuildfstab who is doing system work should not have an uid gid in the normal user range, but in the range 1-999 my 2cts worth of brain damage best regards -- Erich Minderlein <erminderlein(a)locoware.de> MARC Mannheim Rail Commerce GmbH
