## 1.1.1.Introduction

The iPod has largely been an USB device yet there are older models of iPods that used IEEE1394/ / firewire for their connection interface. Historically, it took something of an effort for linux to recognise the iPod model correctly. However, this situation has greatly improved in recent times where it is now possible to simply plug the iPod into a USB port and have your distro recognise it straight off.

gtkpod first and foremost relies on the successful mounting of a recognised iPod. Thus, if the iPod cannot be mounted then gtkpod is NOT going to do it for you! Thus, before firing up gtkpod make sure you can see the filesystem of your iPod at its desginated mount point, eg. /mnt/ipod.

## 1.1.2.Using udev

For linux distros installed with hal and udev, plugging an ipod in and mounting it becomes a trivial exercise. A device node will normally be created under /dev, eg. /dev/sdc.

Using udev rules it is possible to "play" and refine this device node to reflect personal requirements. For example, including these udev rules will allow 2 ipods to be loaded at the same time without interfering with one another:

                        #80GB IPOD
    SUBSYSTEMS=="usb", ATTRS{serial}=="000A2700XXXXXXXX", KERNEL=="sd?2", \
    NAME="80gbipod", MODE="0664", OPTIONS="last_rule"

    #4GB IPOD NANO
    SUBSYSTEMS=="usb", ATTRS{serial}=="000A2700YYYYYYYY", KERNEL=="sd?2", \
    NAME="4gbnano", MODE="0664", OPTIONS="last_rule"

By including the test against the serial number it is possible to uniquely identify an individual iPod and load it appropriately.

## 1.1.3.Mounting

The result of this is that the ipod will be located on a device node and this can be mounted manually using the command (performed as root):

    mount /dev/sdc2 /mnt/ipod

This assumes an iPod is loaded onto the device /dev/sdc and that it is a 2 partition model. It seems that post-2006, iPods have become 1-partition items.

However, it should be noted that moden window managers such as gnome and kde take on the responsibility of managing connected devices. Thus, the result of connecting an iPod will be an icon on the desktop which will either be mounted automatically or can be mounted by the user with a click of the mouse on a popup menu.

## 1.1.4.Environment variables

The following environment variables can be set if needed:

- IPOD_MOUNTPOINT: Defines the mountpoint of the iPod. This overwrites the value stored in the preferences, but is overwritten by the command line argument "-m" or "--mountpoint".
- GTKPOD_DF_COMMAND: Only used on systems without statvfs(). Defines the "df" command to be used for probing the free space on the iPod including command line arguments. Default is "df -k -P". On some systems it may be necessary to remove the "-P" option. The mount point is added to this command line automatically. You can switch off calls to df by setting this environment variable to an empty string.
