Issue on setting up OpenLDAP & Samba following ubuntu tutorial on Oneiric Ocelot

If you're setting up your OpenLDAP Server with Samba support according to the following tutorials:
https://help.ubuntu.com/11.04/serverguide/C/openldap-server.html
https://help.ubuntu.com/11.04/serverguide/C/samba-ldap.html

You will probably stick at the following line.

ldapsearch -xLLL -D cn=admin,cn=config -x -b cn=config -W olcDatabase={1}hdb
Enter LDAP Password:
ldap_bind: Invalid credentials (49)


This issue is based on the problem, that somehow the olcRootPW isn't correctly set, following the instructions of the following solved this issue for me:

Bridge networking with libvirt

For everybody who has trouble setting up bridged networking for virtual machines with kvm, qemu, libvirt on ubuntu 11.10 (oneiric ocelot).

There are a few important settings to take care of.


  1. Set up a bridge on your host system
    Setting up virtualization on Ubuntu with KVM


  2. Disable filtering on your host system
    As can be found on libvirt networking

    The final step is to disable netfilter on the bridge:
    # cat >> /etc/sysctl.conf <<EOF
    net.bridge.bridge-nf-call-ip6tables = 0
    net.bridge.bridge-nf-call-iptables = 0
    net.bridge.bridge-nf-call-arptables = 0
    EOF
    # sysctl -p /etc/sysctl.conf


  3. Configure your VM
    Setting up virtualization on Ubuntu with KVM

  4. Take care that bridged networking ist enabled on your vm:

    • edit your vm-settings:
      sudo virsh edit [vm_name]

    • change interface description to:
      <interface type='bridge'>
      <mac address='[vm-iface-mac-address]'/>
      <source bridge='br0'/>
      </interface>

ICQ Verbindungsprobleme mit Miranda

Wer, wie ich in den letzen Tagen Probleme mit der Verbindungsherstellung zu ICQ Servern hat und folgende Fehlermeldung bekommt
Connection failed.
The server did not accept this client version.


sollte seinen IM-client wie Miranda folgende Einstellungen vornehmen


Host: slogin.icq.com
SSL-Port: 443


oder SSL deaktivieren und folgenden Host verwenden

Host: login.icq.com
Port: 5190


Ein Update auf die neueste Version Miranda 0.9.10 behebt das Problem ebenso.
