waterdrops on cd


Distcc Livecd is a small (less than 50MB) bootable cdrom that contains a uClibc Linux system, the GNU compiler and a distcc daemon. The purpose of this CD is to be able to borrow compile CPU power from computers without installing anything on the harddisk. The CD is build with the Gentoo portage framework.

Unlike distccKnoppix, the C compiler on this CD (the default gentoo hardened gcc compiler) supports position independent code (PIE) and stack smashing protection (SSP).


  • gcc
  • distcc
  • dropbear ssh


How to use

Make sure that the BIOS is confgured to boot from cdrom. On some computers there is a key to press to get a boot menu.

Make sure the computer is connected to the network. It will try to optain an ip adress from DHCP. The address will be displayed on screen.

If your network does not have DHCP you will have to configure the network manually.

Enabling access for your network

By default disccd will allow connections from, and If you are on a different subnet you need to configure distccd to allow your subnet. Log in as root and use nano to edit /etc/conf.d/distccd

# nano /etc/conf.d/distccd

Add or remove --allow entries to the DISTCC_OPTS variable. For example:


After that you have to restart the distccd service.

# /etc/init.d/distccd restart

Enabling SSH access

The ssh service is not enabled by default. To enable it you have to set a root password and then start dropbear.

# passwd

# /etc/init.d/dropbear start

Now are you able to access the computer remotely with ssh.
