Re: [coLinux-users] iPod/gtkpod/colinux?

[Ian B. <ib...@gm...>]

Hmm.. again, I'm not the expert, and I'm only stating what I know from
gleaming information from the code, or what I hear on the IRC chat
lines.

If the device driver in windows presents the iPod as a removable disk
drive, it might be possible to associate that with a /dev/cobd device
and then mount it. But, the only way I know how to do that is through
the \Devices\HardDiskX\PartitionY syntax, and I doubt the device
driver would go to that amount of granularity, if it shows up at all.
Otherwise, the cobd devices are associated with files on the host
side, and thats not what you want.

There is one more solution that I thought up while writing this. Its
to associate your drive letter with a cofs device. I've done this
before with a flash USB device, and it seems to work OK. COFS is
highly experimental though, and is prone to lots of problems. The way
to use it is this:

     1. Get the latest snapshot from monotone or Henry Nestler's website. 
     2. Install the binaries, and use a configuration option as such:
          colinux-daemon <options> cofs0=<drive letter>: <other options>
         (Where <drive letter> is the drive letter of your iPod device)
     3. Boot up coLinux
     4. Attempt to mount as such:
          # mount -t cofs cofs0:/ /mnt -o uid=,gid=
         (Where uid=,gid= has the proper uid and gid of your user respectively)
     5. Browse /mnt.

This should work, as cofs allows you to take any drive from the host system and
see it pretty much unaltered in coLinux. There are issues with it
transferring large
amounts of data, though, and will often give an I/O error with it, so
use with extreme caution.

Lastly, I just realized that if cofs works, SMB will probably work
too. Share out your iPod drive as a share in SMB from your Host
system, then mount it in coLinux to access the files therein. SMB is
extremely reliable in situations like this, and I've used it tons of
times where cofs fails miserably (due to large files, or whatever).

I hope this helps,

Ian
