Installing java 6 on Ubuntu Lucid (10.04)

To install Sun/Oracle java 6 on Ubuntu Lucid do the following in a Terminal window:

sudo apt-get install sun-java6-jre sun-java6-fonts sun-java6-bin sun-java6-plugin

If this says: E: Package sun-java6-jre has no installation candidate then do:

sudo bash -c " echo 'deb http://archive.canonical.com/ubuntu lucid partner' >>/etc/apt/sources.list "
sudo apt-get update

And try again.

When you have installed the packages you should do:

sudo update-java-alternatives -v -s java-6-sun

Dibbler config for Xs4all IPv6 pilot

/etc/dibbler/client.conf

log-level 7

log-mode syslog

iface ppp0 {
        pd
}

Some problems i see with this configuration:

  • the link is not always ppp0 it can also be another ppp interface
  • even when option domain is not specified, it still mutates the /etc/resolv.conf file

  • create a firewall (not included)
  • configure the ADSL modem
  • setting a password on the ADSL modem
  • modifying the loginnaam in the xs4all peer file

Speedtouch ST546 configuration

Restore this configuration file, and change the Administrator password
