Outsource DNS server for rootserver

May 19, 2008 in linux, operating systems | No comments

If you’re running an own rootserver you often are in the situation that you need to make changes on your DNS settings mainly through a web interface of your provider. One main issue is that worldwide update of all DNS servers can easily take over 48 hours.

Zoneedit.com solves this issue. Just connect once your DNS server settings to zoneedit and you’re done. Make all necessary changes then on your zoneedit.com account (for instance rooting of emails to google.com etc.). All these changes are updated in a minute and give you all the freedem you need for all your plans you have with your dedicated rootserver.

Rootserver upgrade to Debian Etch

May 2, 2008 in linux, operating systems | No comments

As of February 2008 1&1 has still only Debian Sarge (3.1) in their standard portfolio for initial installation.
But the move to Debian Etch (4.0) is quite easy. Find below the major steps:
First you need to make a complete installation of the old Debian Sarge stable 3.1 system 64-bit via your 1&1 ControlCenter link.
After first login you can check your Kernel-Version with the following command:

:/# uname -mrs
Output: Linux 2.6.20.21-071108a x86_64

Check the installed Debian Version as follows:

:/# cat /etc/debian_version
Output: 3.1

Updating from Sarge (3.1) to Etch (4.0) - I prefer aptitude nowadays to ‘apt-get’, but apt will work as well.

:/# aptitude update:
:/# aptitude dist-upgrade
:/# vi /etc/apt/sources.list

Insert the following:

deb http://ftp.de.debian.org/debian/ etch main
deb-src http://ftp.de.debian.org/debian/ etch main
deb http://security.debian.org/ etch/updates main

Then type the following commands into your terminal

:/# aptitude update
:/# aptitude dist-upgrade
:/# shutdown -r now

After successfully reboot you should configure the timezone and continue to install all the stuff you want to have on your brand new Debian Etch 64-bit Server.

:/# tzconfig
:/# aptitude install php5 apache2 mysql-server

Rootserver kernel upgrading

April 10, 2008 in linux, operating systems | No comments

Last Update: 2nd November 2008

Connect to your server via ssh and then download the latest kernel version. Best practice is to look first via ftp for the correct file.

Type within your terminal:

ftp update.onlinehome-server.com
User: anonymous
Password: guest
cd local-updates/kernel/deb/
ls
exit

The filename of the latest version is: linux-image-2.6.27.4-20081028a_rootserver.1_amd64.deb
Let’s download this version:

wget ftp://update.onlinehome-server.com/local-updates/kernel/deb/linux-image-2.6.27.4-20081028a_rootserver.1_amd64.deb

Now we have to install the kernel by the following command.

dpkg --install linux-image-2.6.27.4-20081028a_rootserver.1_amd64.deb

Either you check the pointer of vmlinuz to your new kernel in /boot/

ln -sf /boot/vmlinuz-2.6.27.4-20081028a /boot/vmlinuz

Please replace vmlinuz-2.x.y.z by the release you want to add!

or you change /boot/grub/menu.lst accordingly. For the above mentioned kernel it has to look somehow like this:

serial –unit=0 –speed=57600
terminal –timeout=10 serial console

default=0
timeout=5

title linux with serial console
root (hd0,0)
kernel /boot/vmlinuz-2.6.27.4-20081028a ro root=/dev/md1 console=tty0 console=ttyS0,57600

title linux.old
root (hd0,0)
kernel /boot/vmlinuz.old ro root=/dev/md1 console=tty0 console=ttyS0,57600

### BEGIN AUTOMAGIC KERNELS LIST
## lines between the AUTOMAGIC KERNELS LIST markers will be modified
## by the debian update-grub script except for the default options below

## DO NOT UNCOMMENT THEM, Just edit them to your needs

## ## Start Default Options ##
## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
