The second to last line ScriptAlias / /usr/lib/cgi-bin/mailman/listinfo is optional; it makes that when you go to http://lists.example.com/, you will be redirected to http://lists.example.com/listinfo. This makes sense if you don't have any files to serve in the document root /var/www/lists.

Next create the document root /var/www/lists, enable the lists.example.com vhost configuration and restart Apache:

mkdir /var/www/lists
a2ensite mailman.conf
/etc/init.d/apache2 restart

Because we are using a vhost here (lists.example.com), we need to adjust the following variables in /etc/mailman/mm_cfg.py:

VBoxHeadless - Running Virtual Machines With VirtualBox 4.0 On A Headless CentOS 5.6 Server

If your server has more than 4 GB of RAM, make sure you install the Linux PAE Kernel.

sudo apt-get install linux-generic-pae linux-headers-generic-pae

Add thinserver to the Windows Domain

Before we add thinserver to the domain, we're going to have to install Samba along with some other packages.

sudo apt-get install samba smbclient winbind libpam-cracklib krb5-user

Make sure that thinserver is named correctly.

hostname

If the hostname command doesn't return thinserver.domain.internal, rename it to thinserver.domain.internal.

hostname thinserver.domain.internal

Edit the /etc/resolv.conf to use dc.domain.internal as the primary DNS server.

search domain.internalnameserver 10.0.0.10

On your domain controller create a host (A) record in your DNS for thinserver.

Verify that thinserver can resolve domain.internal:

# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

Securing OpenVPN With A One Time Password (OTP) On Ubuntu

"-lpam"

Save the file and lets proceed, shall we?We need to compile this, so thats easy:

make

No errors? Good. It might be that you get an error about "displayQRCode". If so, you will need to make some changes to the makefile. If everything went as it should, you can just proceed.

find /usr/lib -name libdl.so

In the makefile, replace all 3 references to "/usr/lib/libdl.so" with the path you got (e.g. "/usr/lib/i386-linux-gnu/libdl.so").Save it up, and re-run make. You should now be able to proceed just fine.

If it was compiled succesfully, proceed with installing it: make install

We're done, let's proceed shall we?

Configuring OpenVPN to use PAM

Open up /etc/openvpn/server.conf and add the following line:

plugin /usr/lib/openvpn/openvpn-auth-pam.so openvpn

This will use PAM to provide additional means of authentication.The last part (openvpn) is the file in /etc/pam.d we'd like to use. Since we do not want it to interfere with other services (e.g. SSH or sudo) we just use a new file.

Restart OpenVPN to have it re-read the config file.

Configure PAM to authenticate using Google Authenticator

Create the file /etc/pam.d/openvpn:

cp /etc/pam.d/common-account /etc/pam.d/openvpn
vim /etc/pam.d/openvpn

Add the following line:

auth required pam_google_authenticator.so

If you are using encrypted homedirectories, you will need to change that to:

VMWare Image Clone Problem: eth0 Renamed As eth1

After cloning a VMWare image I had noticed that my CentOS Linux server renamed eth0 as eth1, eth1 as eth2 and so on. This is due to wrong or duplicate mac address. To fix this problem login to your CentOS Linux server using console and type the following commands:

# cd /etc/udev/rules.d
# cp 70-persistent-net.rules /root/
# rm 70-persistent-net.rules
# reboot
This file was automatically generated by the /lib/udev/write_net_rules program, run by the persistent-net-generator.rules rules file. Simple delete it and reboot the system to recreate the same. This should fix the problem:

Synaptic Removed From Ubuntu Linux v11.10

Synaptic is a front-end for the apt package management system. The program allows you to perform all actions of the command line tool apt-get in a graphical environment such as installing, upgrading, downgrading and removing of single packages or even upgrading your whole system. The upcoming Ubuntu Linux version 11.10 (code named Oneiric Ocelot) has removed Synaptic Package Manager.

To be frank, I never used Synaptic or so called the Software Center. I use apt-get all the time to install, remove, and update the system or apt-cache to search required packages. Synaptic is fine tool and I'm not sure why Canonical decided to remove the same. Canonical is making lots of new decisions and no one in the enterprise environment like new changes.

Script For Automatically Setting Up A Perfect Server On OpenSUSE 11.4 And Installing ISPConfig 3

, and in the end it also installs ISPConfig 3.

Please note: do not execute this script on an already working server, because this script may overwrite configuration files and break the running system. It is only meant to be used on a fresh installation of OpenSUSE 11.4.

If you are installing on OpenSUSE 11.2 or OpenSUSE 11.3, please be sure to use another version of this script (also available on www.howtoforge.com).

There are few things missing from the tutorial, as I have found it. I have made a script, based on the tutorial, that prepares a system, and which contains several steps that, if not done, leave the system unfinished in some way.

Notable additions:

fail2ban configurationSuSEfirewall2 enabled
Pure-ftpd configuration change (allow renames, change passive ports and permissions) Postfix certificate generation Apache SSL certificate generation, and switching ISPConfig to HTTPSFix of NameVirtualHost apache config with OpenSUSE (important for Apache to recognize multiple domains from ISPConfig) Setup of rdiff-backup with cron Fixed dovecot configuration to enable SSL and support courier-compatibilityFixed pam_mysql to work on 64-bit systemsFixed amavis to find clamd socketInstalled eAcceleratorFixed apache custom errors pathInstall and configure awstatsConfigure apache and awstats to use mod_logio for correct bandwidth measurement

The script is imperfect in the fact that it requires manual entries twice - when mysql_secure_install is run, and when ispconfig_update_svn is run. (I use svn, because ISPConfig latest SVN looks much nicer, but one can type stable as well - on production systems, you should use stable!)

zypper update

and

reboot

before running this script.

Also better change host name (file HOSTNAME) manually with yast2 before running this script, so that OpenSUSE will put a proper name into Postfix configuration.

This script requires two manual actions:

First - when mysql_secure_install is run.
Second - for ISPConfig3 update, if SVN update is chosen, one may need to say 'y' to enable SSL, while for all other options - one can choose a default value by just pressing ENTER.

You should change the following variables in the script before you run it:

THIS_PLATFORM: Either x86_64 or i586.

MYSQLROOTPASS: Please change MYSQLROOTPASS, and be sure to enter it verbatim during the installation of mysql_secure_install.

MY_HOSTNAME, MY_DOMAIN: Change this to your server name. By default it's configured to server1.mydomain.com. If your web site hosts a complete domain, such as domain.com, still leave something for MY_HOSTNAME. server1 or host is a good name.

ISPCONFIG_TAR_GZ: Make sure that ISPCONFIG_TAR_GZ holds the latest available ISPConfig 3 version. Beware, that automatic piping to answer all the questions is set up to work with ISPConfig 3.0.3.3, and you may need to change that part of the script, if ISPConfig is of a later version.

Save the script on your server (e.g. /root/opensuse_ispconfig3.sh):

vi /root/opensuse_ispconfig3.sh

#!/bin/sh

# OpenSUSE 11.4 Perfect Server ISPConfig script by George Yohng (georgesc#oss3d.com)
# Script Version 2.1

# Do zypper update and reboot before running this script

# Also better change host name manually with yast2 before running this script.

# This script requires two manual actions.

# First - when mysql_secure_install is running. One should type a new mysql password, the same as here
# Second - for ISPConfig3 update. One should type 'svn' when the update type is asked
# For both of scripts, all other options are default, one can just press ENTER.

# Also, please change MYSQLROOTPASS below, and be sure to enter it verbatim
# during the installation of mysql_secure_install.

# Important: When setting an MX entry, point it to mail.yourdomain.com rather than
# just to yourdomain.com, and create a CNAME entry for mail. Otherwise it doesn't
# seem to work somehow.

# Platform is x86_64 or i586

Starting with version 4.0, VirtualBox has introduced so called "extension packs" and has outsourced some functionality like remote desktop connection support (VRDP) that was part of VirtualBox packages before version 4.0 into these extension packs. Because we need remote desktop connections to control our virtual machines, we need to install the appropriate extension pack now. Go to http://www.virtualbox.org/wiki/Downloads, and you will find a link to the following extension pack:

VirtualBox 4.0.6 Oracle VM VirtualBox Extension Pack
Support for USB 2.0 devices, VirtualBox RDP and PXE boot for Intel cards.

Download and install the extension pack as follows:

# cd /tmp
# wget http://download.virtualbox.org/virtualbox/4.0.6/Oracle_VM_VirtualBox_Extension_Pack-4.0.6-71344.vbox-extpack
# VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-4.0.6-71344.vbox-extpack

(Make sure you grab the latest version from the VirtualBox web site.)

(Make sure you run the last command with root privileges - # VBoxManage extpack install ... - because otherwise you will get an error like this:

administrator
