Vorbereitung

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
vi /etc/xen-tools/xen-tools.conf
#
# ...
lvm = vg
debootstrap = 1
#
##
#  Disk and Sizing options.
##
#
size   = 4Gb      # Disk image size.
memory = 128Mb    # Memory size
swap   = 128Mb    # 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  = sparse   # Specify sparse vs. full disk images.
dhcp = 1
#
# Default kernel and ramdisk to use for the virtual servers
#
kernel = /boot/vmlinuz-2.6.18-4-xen-686
initrd = /boot/initrd.img-2.6.18-4-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/
# ...

Etch-DomU Image erstellen und anschliessend starten 

xen-create-image --hostname=scx
vi /etc/xen/scx.cfg
xm create -c /etc/xen/scx.cfg
...
ethtool -K eth0 tx off
vi /etc/network/interfaces
# uncomment ethtool
# post-up ethtool -K eth0 tx off

Zusätzliche Pakete installieren

Jetzt die notwendigen Pakete installieren:

  • Apache, Sendmail
  • Postgres
  • Kerberos
  • SASL2
  • diverse Libraries
  • Sun Java
  • gawk, wget, elinks, ethtool, less, host
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 saslauthd 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
apt-get install -u gawk elinks wget w3m less ethtool host

Folgendes habe ich angepasst (siehe unten):

  • Sendmail-Dual Konfiguration
  • Smarthost
  • Masquerading
  • Amavisd-new integrieren

Ich fange mit Amavisd-new, Spamassassin und Clamav an.

Sendmail mit Amavisd-New konfigurieren

Nach der Installation muss Amavis die zentrale Spamassassin-Konfigurationsdatei etc/spamassassin/local.cf untergeschoben werden und dem Benutzer clamav die Gruppe amavis zugeordnet werden: 

apt-get install -u amavisd-new clamav clamav-daemon spamassassin
adduser clamav amavis
mkdir ~amavis/.spamassassin
ln -s /etc/spamassassin/local.cf \
~amavis/.spamassassin/user_prefs

Die Amavisd Konfiguration wird angepasst, unter /etc/amavis/conf.d/50-user: 

use strict;

#
# Place your configuration directives here.  They will override those in
# earlier files.
#
# See /usr/share/doc/amavisd-new/ for documentation and examples of
# the directives you can use in this file
#

@bypass_virus_checks_maps = (
   \%bypass_virus_checks, \@bypass_virus_checks_acl, \$bypass_virus_checks_re);

@bypass_spam_checks_maps = (
   \%bypass_spam_checks, \@bypass_spam_checks_acl, \$bypass_spam_checks_re);

$final_virus_destiny      = D_DISCARD;  # (data not lost, see virus quarantine)
$final_banned_destiny     = D_DISCARD;  # D_REJECT when front-end MTA
$final_spam_destiny       = D_DISCARD;
$final_bad_header_destiny = D_PASS;     # False-positive prone (for spam)

#------------ Do not modify anything below this line -------------
1;  # insure a defined return

Amavisd Neustart: 

/etc/init.d/amavis restart

Sendmail-Dual-Konfiguration

Um Amavisd-New mit Spamassassin und Clamav in sendmail zu integrieren verwende ich das Sendmail-Dual Setup (welches der Konfiguration von Exim mit Amavisd-new entspricht).

Auszug aus /usr/share/doc/amavisd-new/README.sendmail-dual.gz: 

The following setup is described in this document:

 loopback interf.| port 10024            |
            .....|.......................|.............
            : $inet_socket_port=10024    |            :
            :                            |            :
            : $forward_method='smtp:127.0.0.1:10025'  :
            : $notify_method ='smtp:127.0.0.1:10025'  :
            :                                         :
            :    amavisd-new                          :
            ...........................................

Die Sendmail Konfiguration ist unter /etc/mail/sendmail-rx.mc und /etc/mail/sendmail.mc definiert.

Sendmail Routing

Lokale Emails (z.B. root) und die Mails meiner externen Mail-Domain (z.B. ich@neobiker.de) sollen nicht an den Smarthost gesendet werden, sondern lokal an den Scalix-Mail-Server zugestellt werden. Die richtige (externe) Mail-Domain und die (internen) Mail-Domains des LAN trage ich deshalb im File /etc/mail/local-host-names ein: 

localhost
scx
Zuhause.xx
scx.Zuhause.xx
Email-Domain.de

Die beiden Domains (hier: Zuhause.xx und Email-Domain.de) müssen in Scalix als Lokale Domain definiert werden (SAC: Einstellungen - Administration - Lokale Domains).

Der Smarthost für ausgehende Emails wird wie folgt definiert, entweder in sendmail.mc (oder z.B. unter /etc/mail/m4/provider.m4): 

define(`SMART_HOST', `smtp.1und1.de')

Das Login / Passwort für den Smarthost definiert man unter /etc/mail/auth/client-info eingetragen: 

AuthInfo:smtp.1und1.de "U:Login" "I:Login" "P:Passwort"

Ein anschliessendes makemap im Verzeichnis /etc/mail/auth erzeugt die zugehörige Hash-Datei /etc/mail/auth/client-info.db. 

cd /etc/mail/auth
makemap hash client-info <client-info

Zusätzlich trage ich einen Alias ein, damit die internen Mails (z.B. für root) an meinen normalen Account auf dem Scalix Server gesendet werden: 

# cd /etc/mail
# vi aliases
root:     neobiker
neobiker: ich@Zuhause.xx

Sendmail starten

Für den zusätzlichen MTA-RX Prozess muss eine Queue-Verzeichnis angelegt werden: 

cp -p /var/spool/mqueue /var/spool/mqueue-rx

Anschliessend kann Sendmail gestartet werden, vorher zur Sicherheit die Konfigdateien aktualisieren: 

cd /etc/mail
make
m4 /etc/mail/sendmail-rx.mc > /etc/mail/sendmail-rx.cf
m4 /etc/mail/sendmail.mc    > /etc/mail/sendmail.cf

/usr/sbin/sendmail -C /etc/mail/sendmail-rx.cf -L sm-mta-rx -bd -qp
/usr/sbin/sendmail                             -L sm-mta-tx -bd -q15m
/usr/sbin/sendmail -Ac                         -L sm-msp-queue -q10m

Sendmail-Dual Initscript

Ich habe das normale Sendmail-Initscript angepasst, damit der 2.te Sendmail-Prozess (MTA-RX zus. zu MTA-TX) berücksichtigt wird. Die Anpassungen sind im wesentlichen aus den normalen Prozeduren kopiert und angepasst. Im Original werden die Variablen MTAL_XXXX verwendet, ich habe für den zusätzlichen MTA-RX Prozess diese einfach als MTAR_XXXX wo nötig ergänzt und eingefügt.

Das Init-Script sendmail-dual steht hier zum Download. /etc/init.d/sendmail-dual -> Ich habe das normale /etc/init.d/sendmail File ersetzt.

Sendmail starten

Starten wie üblich, zum Debuggen den tail Befehl verwenden, monitoring mit ps: 

# /etc/init.d/sendmail-dual start
# ps aux|grep -v grep|grep sendmail
root      5885  0.0  1.5   8344  2604 ?        Ss   19:11   0:00 sendmail: MTA: accepting connections
smmta     5886  0.0  1.0   8336  1764 ?        S    19:11   0:00 sendmail: MTA: running queue: /var/spool/mqueue-rx
root      5890  0.0  1.5   8332  2612 ?        Ss   19:11   0:00 sendmail: MTA: accepting connections

Scalix Installation

Sourcen laden

Sourcen laden und unter /usr/src auspacken: 

cd /usr/src
wget http://downloads.scalix.com/.community/11.0.2.1/scalix-11.0.4-GA-debian-intel.tgz
tar xvzf scalix-11.0.4-GA-debian-intel.tgz

Installieren

Das Pakage war bei mir korrupt, in einem Tomcat-Paket ist ein Syntaxfehler. Den beheben wir 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 könenn wir die Scalix-Pakete installieren: 

cd /usr/src/scalix-debian-11.0.4-GA/software/scalix-server

dpkg -i ../../third_party/libical/i386/libical*.deb
dpkg -i scalix-server_*.deb

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.

Um Ressourcen zu sparen, kann man den Speicherbedarf des Tomcat etwas zügeln: /etc/opt/scalix-tomcat/scalix-tomcat.conf
