centos vmware zimbra

vmware ESXi 4 + centos 5.3 guest OS + zimbra

I’ve been playing around with Zimbra opensource edition on my development server. Zimbra is a full-featured, open source collaboration suite for email, group calendaring, contacts, and web document management and authoring. web interface is equipped with AJAX and it is compatible with clients such as Outlook, Apple Mail, and Novell Evolution so that mail, contacts, and calendar items can be synchronised from these to the ZCS server. It also can be synchronized to many mobile devices. ZCS makes use of many existing open source projects such as Postfix, MySQL, and OpenLDAP.

In this experiment i was using Zimbra 64bit_x86 opensource edition

DNs setting

mail.domain.tld.        A    192.168.1.2

bind9 centos

Upgrading Bind9 on centos 4.7

I’ve just upgrading one of my dns server recently. Orginaly centos 4.7 using bind-9.2.4-30.el4_7.2. Although this version not affected by cache poisoning vulnerability. as Dan Kaminsky announced a massive, multi-vendor issue with DNS that could allow attackers to compromise any name server. Here’s how to upgrade bind-9.2.4 to bind-9.5.0.

Download the SOURCE rpms

# wget http://patrick.vande-walle.eu/upload/bind-9.5.0-33.P1.src.rpm

Compile/Build source RPM

# rpm -Ivh bind-9.5.0-33.P1.src.rpm
# cd /usr/src/redhat/SPECS/
# vi bind.spec

find this lines

# configuration files:
tar -C ${RPM_BUILD_ROOT} -xf %{SOURCE28}

change it to

tar -C ${RPM_BUILD_ROOT} -xjf %{SOURCE28}

Source28 is tar.bz2 file so we need tar -xjf options
