Scalix mit Debian Etch

Vorbereitung

Ich habe Scalix in einer XEN-DomU installiert. Das ist natürlich optional. Ausserdem verwendet Scalix sendmail anstatt Exim als smtp-daemon. Analog zur Exim Installation habe ich sendmail in einer Dual-sendmail Konfiguration zusammen mit amavisd-new installiert, welche spamassassin und clamav als Spam- und Virenscanner integriert.

Etch Installation in XEN DomU

Ich starte mit der Installation auf einer frischen Etch-Installation unter XEN. Der Einfachheit halber benutze ich die xen-tools.

apt-get install xen-tools

Konfigdatei /etc/xen-tools/xen-tools.conf:

#
# ...
lvm = vg
debootstrap = 1
#
##
#  Disk and Sizing options.
##
#
size   = 4Gb      # Disk image size.
memory = 256Mb    # Memory size
swap   = 512Mb    # Swap size
# noswap = 1      # Don't use swap at all for the new system.
fs     = ext3     # use the EXT3 filesystem for the disk image.
dist   = etch     # Default distribution to install.
image  = full     # Specify sparse vs. full disk images.
#
# Uncomment and adjust these network settings if you wish to give your
# new instances static IP addresses.
#
gateway   = 192.168.2.1
netmask   = 255.255.255.0
#
# Uncomment this if you wish the images to use DHCP
#
#dhcp = 1
#
# Default kernel and ramdisk to use for the virtual servers
#
kernel = /boot/vmlinuz-2.6.18-6-xen-686
initrd = /boot/initrd.img-2.6.18-6-xen-686
#
# The default mirror for debootstrap which can be used to install
# Debian Sid, Sarge, and Etch.
#
mirror = http://ftp.de.debian.org/debian/
# ...

XEN-DomU (Etch) erstellen, die DomU starten und die Netzwerkkonfiguration der DomU vornehmen:

xen-create-image --hostname=scx --ip=192.168.2.51

vi /etc/xen/scx.cfg               # XEN-Config Anpassungen

xm create -c /etc/xen/scx.cfg     # DomU starten
scp xen1:/usr/sbin/ethtool /usr/sbin  # ethtool aus der Dom0 in die DomU kopieren
aptitude install ethtool locales

/etc/network/interfaces: IP, DNS, Gateway etc. konfigurieren

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
 address 192.168.2.51
 gateway 192.168.2.1
 netmask 255.255.255.0
 dns-nameservers 192.168.2.20
 dns-search zuhause.lan
 post-up  ethtool -K eth0 tx off

# The commented out line above will disable TCP checksumming which
# might resolve problems for some users.  It is disabled by default
#

Zusätzliche Pakete installieren

Jetzt die für Scalix zusätzlich notwendigen Pakete installieren:

• Apache, Sendmail
• Postgres
• Kerberos
• SASL2
• diverse Libraries
• Sun Java, python
• gawk, wget, elinks, ethtool, less, host
• libmilter0 (ab 11.4.2, wird aber nicht unbedingt verwendet)

apt-get install -u apache2 sendmail sendmail-doc
apt-get install -u postgresql
apt-get install -u krb5-config krb5-doc krb5-user libkadm55 libkrb53
apt-get install -u libsasl2-modules libsasl2-gssapi-mit sasl2-bin libssl0.9.7
apt-get install -u libxml2 libglib2.0-0 libstdc++2.10-glibc2.2 libstdc++5
apt-get install -u sun-java5-jre python
apt-get install -u gawk elinks wget w3m less ethtool host bzip2
apt-get install -u libmilter0

Folgendes habe ich anschliessend angepasst (siehe unten):

• Sendmail-Dual Konfiguration
• Smarthost, MasqueradeAs
• Amavisd-new, Clamav, Spamassassin integrieren

Ich fange mit Sendmail, Amavisd-new, Spamassassin und Clamav an. Für Spam- und Virenfilter verwende ich das volatile Repository, da diese Programme häufig zu aktualisieren sind und die alten Versionen aus stable teilw. Fehler produzieren (Clamav 100%CPU).

Sendmail unter Debian Etch

Unter Debian ist standardmässig Exim als Maildaemon installiert. Scalix verwendet und konfiguriert sendmail.

Hier beschreibe ich meine sendmail Installation unter Debian Etch zusammen mit amavisd-new, clamav und spamassassin.

Wenn die Email-Konfiguration mit sendmail funktioniert, kann Scalix installiert werden. Die Scalix Installation passt die sendmail Konfiguration so an, dass Emails an den Mail-Server Scalix ausgeliefert werden.

Scalix Installation

Sourcen laden

Sourcen laden (82MB) und unter /usr/src auspacken:

cd /usr/src
wget http://downloads.scalix.com/.community/11.0.4/scalix-11.0.4-GA-debian-intel.tgz
tar xvzf scalix-11.0.4-GA-debian-intel.tgz

bzw. bei den neueren Versionen (inkl. Stand heute 11.4.3)

wget -c http://downloads.scalix.com/.community/11.4.2/scalix-11.4.2-GA-debian-intel.bin
sh ./scalix-11.4.2-GA-debian-intel.bin

Installation

Das Pakage von 11.0.4 war bei mir korrupt, in einem Tomcat-Paket ist ein Syntaxfehler. Den behebe ich zuerst:

cd /usr/src/scalix-debian-11.0.4-GA/software/scalix_server
mkdir -p new/DEBIAN old
mv scalix-tomcat_5.5.16-263_all.deb old 
dpkg -x old/scalix-tomcat_5.5.16-263_all.deb new
dpkg -e old/scalix-tomcat_5.5.16-263_all.deb new/DEBIAN

vi new/DEBIAN/postinst
# ... Zeile 21 die überflüssige ')' entfernen
    /opt/scalix-tomcat/bin/sxtomcat-create-instance ""
# ...

dpkg -b new scalix-tomcat_5.5.16-263_all_patched.deb

Jetzt kann man die Scalix-Pakete installieren (update einer vorhandenen Installation siehe hier):

Jetzt sollte man sich in o.g. URL als sxadmin und dem vorher definierten Password einloggen können. Als sxadmin kann man in der Scalix Admin Console (SAC) neue User anlegen.

Zuerst sollte man dem Scalix Mailserver zusätzlich die richtige (externe) Mail-Domain beibringen. Das trägt man unter "Einstellungen - Administration - Lokale Domains" ein. Bei mir sind 2 Einträge vorhanden

• neobiker.de
• Zuhause.xx

Um Ressourcen zu sparen, kann man den Speicherbedarf des Tomcat etwas zügeln (das ist im install-skript bereits eingebaut):

/etc/opt/scalix-tomcat/scalix-tomcat.conf

# Configuration file for Scalix Tomcat

# The directory where Java is installed
# (determined from /usr/bin/java managed by update-alternatives
# by default, change to hardcoded path if needed):
JAVA_HOME="`/opt/scalix-tomcat/bin/determine-java-home`"

# Additional arguments to be passed to Java:
JAVA_OPTS="-server -Xms40m -Xmx40m"

# Maximum number of file descriptors
ULIMIT_NUM_FILES="1000"

Webmail per DMZ-Proxy und SSL-Zugriff

Gesicherten Zugriff auf den Webmail Client von Scalix realisierte ich über einen Apache-Server in meiner DMZ. Hierzu installiert man das scalix-tomcat-connector Paket in der DMZ. In der Firewall muss Port 8009 von der DMZ zum Scalix-Server freigeschaltet werden.

dpkg -i scalix-tomcat-connector_11.0.4.25_all.deb

        ProxyPass /webmail ajp://scx.neobiker.lan:8009/webmail
