Change Default Crypto Loaded Algorithm

Hi there!

After my NVIDIA card died I decided it was time to buy an AMD card again (R9 270X), but I didn't think AMD drivers were such a pain in Linux as people said. Of course, in some distros anyway. On Arch, for example, there's no official release because Arch's developers would have to hold Xorg in order to make a closed-source driver available, because AMD's pace isn't in pair with Linux. So in order to install AMD's drivers on Arch I must rely on some guy's unnoficial repositories, but that isn't the whole problem. Even though I'm cool with adding repos and downgrading Xorg, I'm not cool with it not working for a lot of apps, so that's where I decided to try a few distros. Manjaro is a no-go because it installs Flash as default. openSUSE although is a very good distro, is a complete mess when it comes to repositories, specially multimedia ones. Ubuntu/Mint are also a no-go, Ubuntu because after 12.04 they have a spyware by default, and Mint because it contains non-free stuff by default.

So here I come! I ran Debian in the past for a long time (aside from a breaf period last year) and it was lovely, I could easily set up a custom encrypted install, but now I don't remember how to, and it's killing me. I don't like how the installer doesn't show the partitions size as they actually are, and I don't like how the automated encrypted LVM setup doesn't let me chose the encryption algorithm or the timeframe between each passphrase attempt. That's why I must create my install, and here's what I used to do on Arch (the part that really matters), converted to what I use on Debian:

Code:

# modprobe dm-mod

(create one 1GB partition for /boot, unencrypted ; create another big 930 GB formatted as "8e" - LVM - on dev/sda2)
Code:

# fdisk /dev/sda

(chose my ciphers and iter time)
Code:

# cryptsetup -c twofish-xts-plain64 -y-s 512 --iter-time 5000 luksFormat /dev/sda2

(open the luks container on "sda2_crypt")
Code:

# cryptsetup open --type luks /dev/sda2 sda2_crypt

(create physical volume on sda2_crypt)
Code:

# pvcreate /dev/mapper/sda2_crypt

(create volume group "debian" on sda2_crypt)
Code:

# vgcreate debian /dev/mapper/sda2_crypt

(create volumes)
Code:

# lvcreate -L 8G system -n root
# lvcreate -L 60G system -n swap
# lvcreate -l 100%FREE system -n home

After this is done, I go to the "partition disks" page where I select each partition/volume to it's correct destination. I then procceed to installing the base system, configuring apt, and all that. Now, before I install Grub I used to execute the following commands on shell:

Code:

 # nano /etc/crypttab

I used to put something there, but I don't remember what exactly. It's been a long time since I used Debian for long! But here's what I put the

Code:

sda2_crypt /dev/mapper/sda2_crypt none luks

Then I procceeded to instal syslinux (I REALLY don't like GRUB)

Code:

# chroot /target
# apt-get install syslinux

But I get the following error:

Quote:
E: cannot write log (Is /dev/pts mounted?) - posix_openpt (2: No such file or directory).
I'm assuming this is just a non-critical error. But this is not the problem, the problem is when I try to install syslinux:

Code:

# syslinux-install_update -i -a -m

The output:

Quote:
/bin/sh: 2: syslinux-install_update: not found
Then I type "syslinux --help":

Code:

# syslinux -h

I tried literaly every possible combination that would make sense in Arch and yet I can't install it. The Debian documentation on syslinux doesn't help at all, and the Arch's Wiki on Syslinux... well, tells how to make it work on Arch It used to work the same way on Debian, but now it doesn't.

Here's a little list of the errors I get:

Code:

Oh, and also users are still not able to press TAB to get the full command without typing it? And we can't even press the up arrow key that we get "^[[A"? :P Whaat?

What am I doing wrong?

I'm really not with the time to mess with these kinds of things, so either I figure this out REAL SOON or I'll be forced to get back to Windows

Hello all

i need to install ns2.34 in centos 6.6

with this
http://bhavanme2011.blogspot.com/

but i can t install the packages

yum install autoconf
yum install automake
yum install gcc-c++
yum install libX11-devel
yum install libX-devel
yum install libXt-devel
yum install libXmu-devel
yum install xorg-x11-proto-deve
finally
yum update audit

when i execute it

i have this msg

You need to be root to perform this command.

I have made a change to GRUB2 bootloader in etc/default/grub.
Now I need to run 'update grub' for the change to take effect.
However, the 'update grub' command on the terminal is giving this error message:
Code:

root@debian:/# update grub
bash: update: command not found

Can someone please explain why this command is no longer working?

I've had to make a change to grub because I tried to install a new distro which meant I had to alter grub.
The install wasn't successful so I deleted the grub file and then re-installed it.
The re-installed grub needs a change so I can get sound on my pc.
However, I can't add these changes because the 'update grub' command doesn't work.

I've checked the grub file with another debian distro and they are both the same.
So now I don't know if I need to check if a different grub file is the problem or anything else.
Can someone help?

I don't know why I want this, but is there a way the Code:

sudo aptitude install <package>

or Code:

sudo aptitude upgrade

command could bypass the confirmation stage? It's always occurred to me shouldn't there be some command parameter for install/upgrade that does the work?

Let me give an example. Suppose I want to install Variety, the wallpaper changing application. Now, I know that I want to install the software with all the dependencies it requires to install/run - the entire package. So, isn't it obvious that I would press Y when aptitude shows the info what it's going to download/install and asks for permission?

I can't, however, imagine scenarios when seeing that information I'd change my mind and press N to abort the install/upgrade procedure.

I have tried installing a Ubuntu OS onto a partition (sda3).
When I had difficulties with the install, I decided to delete everything from the partition.

But now when I boot the computer, I get taken to the 'grub rescue' prompt.
I have tried to find grub in my other partitions (sda1 and sda2).
However, the command 'ls (hd0,msdos1)/' for example, does not show a grub directory.
It must've transferred grub to sda3 somehow and now I've deleted it.

I have debian live USB and am trying to install grub with:
Code:

apt-get install-grub /dev/sda

But I get the error message:
Code:

bash: grub-install: command not found

So now I don't know what's going on. Can anyone please help?

I use Redhat 6.3 , when I install run "yum install vsftpd" , it pops the following error, does it mean the library is not support , I have to update the kernel ? thanks

How do I install OpenSuse without having a DVD and end up booting from the C: drive?

Hi experts,

so the steps to install kvm is this:

Code:

sudo apt-get install qemu-kvm libvirt-bin bridge-utils virt-manager

according to this webpage: http://www.howtogeek.com/117635/how-...nes-on-ubuntu/

Can I make this simpler?

I want to do just one command: sudo apt-get install kvm, and it should call and install all these packages.

Thanks
