DSM-G600, DNS-3xx and NSA-220 Hack Forum

This is great, been looking for it earlier, but I didnt find it. A few questions.
What hardware version of 323 do you run?
Does it support all HW, fan, Thermometer?

I am currently reloading into a fonz modified version of the dlink 1.04. It has true NFS server support. It is working well so I may not risk messing it up. Anyhow would be nice with access to a debian repo.

For 2 years, I was doing what you were doing though with a 1.05 Firmware.
I.e., reloading the firmware so that I could compile in true NFS support which I used to run BackupPC off my main Linux server.

HOWEVER, BEWARE -- NFS CONFLICTS WITH EXT3 -- specifically, when using ext3 (but NOT ext2), the NFS directory cache gets corrupted (particularly if you are accessing a lot of inodes like with 'find') so that some files and directories transiently don't show up until the cache is refreshed. This only occurs on the NFS side. I was never able to get anybody to help with fixes other than suggesting upgrading the kernel since the old 2.6.12 kernel is known to be buggy. In any case if you use ext3 you can get severe file corruption due to the wrong directory data.

So for the past 2 years I have run under ext2 - but ext2 doesn't have journalling and that is a particularly bad deficit on the dns-323 where it is often hard or impossible to shut down cleanly (particularly without console access) and where it is not easy to even run fsck to check and fix for errors (since you need to reload root and /ffp elsewhere so you can unmount the drive).

The bottom line is that I finally got around to installing a modern kernel and real (Debian) root so that I can now do things right and protect my data.

I gave it a try.

When chrooting to lenny armel i get seg faults. Tried also lenny arm. Here I can chroot into it. So tried move on with arm instead, but I only found orion built for armel. So it seemed like a dead end to me and my skillset (and current determination or lack of it).

edit:
Tried squeeze armel it also segmentationfaults when chrooting.

edit again:

I found some info on this.

http://dns323.kood.org/forum/viewtopic.php?id=5231

I seems the conclusion in the thread is that armel cannot be chrooted with the stock kernel. What kernel did you use when chrooting?

Next step would be to reload a newer kernel and try again. Maybe alt-f is a prepacked ready to go platform for this. I will give it a go.

If you are talking about doing the chroot to set up the new Debian installation, then you are right, you can't chroot into an armel installation from the old 2.6.12 arm1 kernel.

I ended up using a plugcomputer running a recent armel installation to complete the chroot.
Alternatively, I think there is a way to divide the setup into a 'stage 1' and a 'stage 2' installation.
In stage 1 you basically just use cdebootstrap to download the packages.
The command is:
cdebootstrap --foregin -aarmel  --include=locales,initramfs-tools,libuuid-perl lenny <lenny root> ftp://ftp.debian.org/debian

Then you need to complete stage II on an armel machine (e.g. the dns-323). I haven't investigated exactly how to do it but I imagine it would involve putting a kernel on the partition and reloading into that kernel and then letting an auto-install type script finish the job (you will have to google to fill in the missing steps since I didn't have to do it that way.

Alternatively, if you or anybody else, can provide a couple of hundred MB of upload space, I saved a virgin copy of an armel Debian install that I would be willing to upload for you and anybody else who wants it. Obviously, from there you could customize etc.

Sounds great, but will this also work on the Conceptronic CH3MNAS ?

Thanx for the upload, but I never got it working, i guess i need to read up and try harder. Also figured out I have a A1 revision despite what the sticker says.
I bougth another used A1 for really cheep and a nokia cord to make a seriel cable. I d like to learn more.

I imagine you will need to try it (either that or buy me a Conceptronic to play with )

OK, this is what I did so far:
- HW CH3MNAS with latest FW
- Fonz_plug 0.5 is installed
- built a lenny ARM distro on a debian system
- tried to chroot it but got the error "chroot: cannot execute /ffp/bin/sh: No such file or directory"

A bit confused now...

Please help.

Thanks, Bert

The following will run a bash shell in a debian chroot stored in the /mnt/md0/debian directory:

CHROOT="/mnt/md0/debian"
chroot $CHROOT /bin/bash
