OpenLDAP replication on Ubuntu Lucid with cn=config backend

von Mario Rasser

Introduced with Ubuntu 9.10 OpenLDAP uses the cn=config-Backend for “live” configuration of the LDAP-Server without restarting the service. The benefit of the “live” config feature is bought by a complexer configuration with LDAP Syntax and LDIF-Files.

I will describe a easier way to setup a OpenLDAP Replication using slapd.conf as a base for the cn=config-Backend.

The shown way is based on OpenLDAP shipped with Ubuntu 10.04 LTS (Lucid) using SSL. The master LDAP-Server configuration is not part of this HowTo. So we are considering you have a running Master LDAP Server, that is already configured to provide LDAP Replication mechanism.

(Arrow) keys are not working in VMWare guest

von Mario Rasser

We had problems within some keys like Arrow, Up, Down etc. in the Guest OS running on a Ubuntu 8.10 and 9.04 running VMWare Server 2.0. The keymapping between host and guest is broken. That could be fixed with the following entries in ~/.vmware/config (create the file if it is not existing). The file is located in the home of the user that runs ther VMWare Console, e.g. from the VMWare Infrastructure Web Access environment.

xkeymap.keycode.108 = 0x138 # Alt_R
xkeymap.keycode.106 = 0x135 # KP_Divide
xkeymap.keycode.104 = 0x11c # KP_Enter
xkeymap.keycode.111 = 0x148 # Up
xkeymap.keycode.116 = 0x150 # Down
xkeymap.keycode.113 = 0x14b # Left
xkeymap.keycode.114 = 0x14d # Right
xkeymap.keycode.105 = 0x11d # Control_R
xkeymap.keycode.118 = 0x152 # Insert
xkeymap.keycode.119 = 0x153 # Delete
xkeymap.keycode.110 = 0x147 # Home
xkeymap.keycode.115 = 0x14f # End
xkeymap.keycode.112 = 0x149 # Prior
xkeymap.keycode.117 = 0x151 # Next
xkeymap.keycode.78 = 0x46 # Scroll_Lock
xkeymap.keycode.127 = 0x100 # Pause
xkeymap.keycode.133 = 0x15b # Meta_L
xkeymap.keycode.134 = 0x15c # Meta_R
xkeymap.keycode.135 = 0x15d # Menu


Install VMWare Tools on Ubuntu Server

von Mario Rasser

How to install VMWare Tools on Ubuntu (tested on Ubuntu 8.10 and 8.04 LTS) in a rush:

  • Within your VMWare Infrastructure Client or WebGUI do a “Install VMWare Tools”
  • VMWare will provide a ISO Image with the VMWare Tools to the Virtual Machine
  • SSH to the Ubuntu Server you want the VMWare Tools be installed
  • OPTIONAL but prefered:
    sudo su -
    aptitude update
    aptitude full-upgrade
  • do the following steps as root or prefix a sudo:
    aptitude install build-essential linux-headers-`uname -r`
    mount /dev/cdrom
    cd /media/cdrom0/
    cp VMwareTools-2.0.0-122956.tar.gz /usr/src/
    cd /usr/src/
    tar xfzv VMwareTools-2.0.0-122956.tar.gz
    cd vmware-tools-distrib/
    # answer the question via defaults
    init 6
