Re: Does jessie install grub on both raid0 disks?

 Hello:
 I was unable to trace whether new debian installers include for amd64
an option to install grub on both disks of a raid0. If yes, it would be
convenient to carry out a new installation of jessie instead of
dist-upgrading from wheezy. Wheezy - at the time I upgraded to it - had
no such option.

 Thanks

Just in case, my 2 cents.

If there is an option to install the grub boot loader on _every_ disk of
a raid system, it would make sense to do it in a way the systems boots
when sda is dead or missing. Worst case would be, do install the uuid
from the first disk aka /dev/sda on both grub installations as location
for the kernel and initramdisk.

Furthermore I expect that dpkg-reconfigure grub will give me the new
option and I don't need a new installation.

Yours, Ralf

 ... I must confess that I am confused, or my description was unclear. Hope 
 not to bother you, I
summarize my procedure;
 Using the amd64 wheezy beta 4 installer, downloaded Feb 1, 2013, I got
the same situation as described above by fdisk -l.
 That installation ended by asking install grub on /dev/sda?.
 I accepted the proposal, whereby the terminal showed grub-install /dev/sda
 update grub
 At next boot, I run
 grub-install /dev/sdb
 which was accepted without any error or warning message.
 After shutdown -h now, trying to boot, the system entered grub
rescue. ...

Hello debian users,

I can verify the error Francesco reported. I have a Laptop, swapped the
optical drive for a ssd. To test debian 7. There is already windows and
debian 6 on sda with grub installed on sda. The installation was fine an
ended with grub installing two Linux boot entries (sda, sdb) and one
entry for windows on sda (very sad you can't choose the device grub
should install at this point). And it does work well.

As I thought by myself: It would be nice to use the ssd as an emergency
(usb) boot device for other computers, it was mbr formated and the root
partition was marked as bootable. So it should have grub installed to
it, too.

I thought grub-install /dev/sdb should be enough to make the sdb
bootable. Done that without an error message. But ...

I restarted the Laptop, telling the BIOS to boot from ssd (sdb) ... I
get the error: symbol not found: 'grub_divmod64_full'
And all I get is the 'grub rescue' prompt.

On the other hand ... I have a desktop running windows on sda (without
grub) and debian 7  grub on sdb. To boot into Linux, I change the BIOS
boot device to sdb. I have choosen the sdb even before installing Linux.
I assume Linux isn't messed up by this. But on the Laptop (or Francescos
raid1 setup)  it gets confused, because the BIOS (or the lost raid1
drive) changed the numbering of the disks?

But what's the point of installing grub on more than one disk, if it
doesn't boot when one disk is missing?

Thanks

 Which won't help him if he's on stable and doesn't have backports

 $ sudo apt-get install openoffice.org

 And in the backports case you still need -t squeeze-backports:

Hi,

you suggest, that he rents a room, put a table and a chair in it, buys a
computer, printer, phone, Internet connection and hires a secretary?
Could be a valid solution. If he gets a Linux computer we're even on the
track from post one.

Regards,

Ralf

Re: apt: cron.daily necessary?

2009-09-08 Thread Ralf Saalmüller

Hello to all amd64 users,

there is a check in my /etc/cron.daily/apt script that uses  
on_ac_power to find out if it's running on battery. It should _not_  
start when on battery, I guess. Don't know if that runs as it should  
do, I have a desktop.


Something different. There is a sleep command involved. So it takes a  
long time to run but doesn't generate much fuzz on my system. Perhaps  
it isn't red handed?

Hi all,

I would like to discuss and suggest the following thing:

On my 64-bit notebook I am using anacron and (of course) apt. In the  
apt
package included is the file /etc/cron.daily/apt, which contents  
some lines,
which are starting a find process. This find process initiated by  
apt (and I
hope, I am right with this information of the initiation source)  
consumes a
lot of harddrive actions for several minutes after boot, which makes  
the

computer at this time rather slow.

Of course, it is one of the processes started by anacron.

IMO this is an annoying situation for notebook users, as sepeciela ,  
when you
just want to start, wanted to do some things quickly, and then  
shutting down

again - just as many notebook users do!

My suggestion to this problem are these:

1. delete /etc/cron.daily/apt manually

O.k., this can be easily done, but how necessary is this file at all?


2. If this file is not very necessary do not put /etc/cron.daily/apt  
into the
apt-package, but maybe it should be put into some other package (for  
example

cron-apt), or , another opportunity, as a standalone package.


3. put this file to cron.monthly or cron.weekly, or, let it start  
manually

somehow (this third option was just a thought)

What do you think? Is there a way and a chance, to improve things? Any
feedback will be very welcome.


Best wishes

Hans-J. Ullrich

Re: How can I set going more one Tor daemons?

Why?

To torify web browsing, all you have to do is install an add-on to  
firefox.


If you like to share some bandwidth to the tor community, install one  
tor daemon on your internet connection.


A nice combination is a squid server in your local net and link the  
squid to a tor daemon on the same machine. I've set up a cascade with  
tor to privoxy to havp to squid. And if I choose the squid proxy,  
it's routed through through the cascade and leaves through tor. On  
every machine and browser that's configured to use the proxy.


So why would you like to run one tor deamon for every user on one  
machine when one daemon for all users of your local net will do?


As tor is a daemon, why would someone like to start one for every  
user? You don't start a nfs server or a sshd server for every user?


A little bit puzzled.

If it's a matter of life and death you should consider something more
