The powerpmac can directly install Linux software if it has been properly setup to reach the Internet. The steps are below. 1) The /etc/network/interfaces file must contain a valid gateway to reach the Internet from your facility. You should obtain this from your IT department. Windows users on the same network can figure this out by typing ipconfig /all from a Windows command prompt. 2.) The appropriate nameserver must be setup in the /etc/resolv.conf file. You should obtain this from your IT department. 3.) In addition for flash systems the filesystem is mounted readonly for reliability. Therefore, you must remount the root filesystem to be writable with the mount -o remount,rw / command 4.) Often programs write data to the /etc folder after installation. /etc is mounted using a tmpfs and aufs file system. To insure the changes made to /etc are permanent you must copy the contents of /.readonly/etc-tmpfs-mirror to /.readonly/etc 5.) Afterwards remember to restore your file system to read only mode with the mount -o remount,ro / command Below we will take you through an example of installing the linux partioner parted on the the powerpmac. root@10.34.9.222:/.readonly/etc-tmpfs-mirror# cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them.

As our pakage is old the location for the archive updates need to modify for updates. Type these commands form the terminla on PowerPMAC to make necessary change to the file and then use apt-get to load new pakages. -------------------At powerPmac Terminal type------------- mount -o remount,rw / echo "deb http://archive.debian.org/debian/ lenny main non-free contrib" >/.readonly/etc/apt/sources.list echo "deb http://archive.debian.org/debian/ lenny main non-free contrib" >>/.readonly/etc/apt/sources.list echo "deb http://archive.debian.org/debian/ lenny main non-free contrib" >>/.readonly/etc/apt/sources.list mount -o remount,ro / reboot --------------------------------------------------------------
