Unslinging help

I haven’t tried to do this, so I can’t offer point-by-point solutions, but I can offer that the standard response to “I don’t have a linux machine” is knoppix — it’s a cd-bootable linux distribution that you can use on any machine to get linux tools etc. I’m sure it would work for partitioning your flash device.

Thanks Ron. I actually decided to cut bait on the memory stick idea and opted for reformatting the hard drive.

I have successfully unslung and run /opt/etc/init.d/S60mt-daapd. Now a couple additional problems:

-I can’t copy any mp3 files in my new directory /share/hdd/data/public/mp3/ using explorer – it says that access is deined…my guess is that in order to get into the admin folder I used the NSLU2 username and password, but at this point I probably need to somehow login using the root username and password. Not sure how though.

-I don’t see mt-daap running in iTunes or access it through the config address.

Thanks again for your help and advice.

if you set a password for root, you’ll have to ssh in using something like putty, I believe. Otherwise, you can telnet into the machine.

Once you are telnetted in, you should be able to do something like:

chmod 777 /share/hdd/data/public/mp3

and that will set that folder to be world readable and writable. That should get you running. You might want to play with permissions later to tighten them down, if you need to in your environment.

I am trying to use a 256MB memory stick as the second drive. When I went through the process of formatting through the web interface, the format of the drive (shown in the interface) went from FAT to “Not Formatted”. When I plugged the stick into an XP machine, it stated that the drive format was RAW, so I used disk manager to delete the partition and put a FAT partition back into the stick. To compound the problem, I am also a big time linux newbie. Matt

From one Linux newbie to another. I unslung my second NSLU2 to a 1GB memory stick in Disk 2 as I wanted to use it as a web server and for now don’t want to have a hard drive online 24/7. While the overall documentation for the unslung process is very good, the information on unslinging to a memory stick is not. I searched for days trying to understand the process. For me, when I got to the step of “hot plug the flash drive” in, the flash drive was formatted FAT and it would not format as EXT3. I found the answer that worked for me in a message on the Yahoo board. After hot plugging the flash drive in, I had to telnet in and run:

FDISK /DEV/SDA

I was then able to format the flash stick as EXT3 and finish the unslinging process.

I am so happy with my web server that I may just ‘upgrade’ the flash stick to a 2GB or 4GB unit when I fill up the 1GB stick. By the way, thumbnails for images are the main culprit in wasting lots of flash disk space.

Well, I spent lot of time on my nslu2 and formating also.

I can say now I’m not bad in unslinging process.

The pb is that the fdisk tools provided is linksys specific and dont’ let you do custom partition

The first thing is to do a unslung on stick formated with web interface. just to have ipkg functionning. after that the tip is to get a real fdisk tool. So what I’v done :
ipkg install busybox-base (base do not create links, just have the executable)

after that copy on the internal flash of the slug but do not overwrite the original (Version 0.6)
current version of busybox is 1.3 so I do
cp /opt/bin/busybox /bin/busybox1.3

So like this in any case you boot your slung (even with no disk attached) you can do a real fdisk (if you have a disk sure) doing :
busybox1.3 fdisk -l /dev/sda
list all partition table. But you can create partition as you wish and size you want.

After that, boot with no disk. after boot, plug your stick and partition it like you want.
After, to format stick drive that can be seen by slug you really need to format it with web interface. but it will not work because web interface invokes linksys specific fdisk. So the tip is to fake the linksys fdisk
go here to section faking the slug
http://www.nslu2-linux.org/wiki/HowTo/UseAMemoryStickAsMainDrive

So with that you can use real fdisk to partition as you want and resling

here what I have on my slug /sbin

# cd /sbin
# ls -al fd*
-rwxr-xr-x 1 root root 10 May 8 2004 fdisk
-rwxr-xr-x 1 root root 64064 Jan 1 1970 fdisk.old
-rwxr-xr-x 1 root root 10 May 8 2004 fdisk.sh
# cat fdisk
#!/bin/sh
# /bin/busybox1.3 fdisk -l /dev/sda

Hi Fizze,

Ok you’ve got like same config as mine
256 Mb flash on disk 2 and 300Gb NTFS on disk 1.
disk 1 has also 256Mb swap partition.

Every time I boot mt-daapd or browse my share my slugs freeze.

Got 5000 MP3 and 100 static playlist. I was asking if it was not my flash that cause pb, so replaced my flask usb with 3Gb old HDD, fresh unsling, ipkg openssh and mt-daapt latest nighties and got same pb (freeze on first scan) even when I removed songs.db

Do you have this kind of pb ? (I also done that on a 2nd slug with same pb)

thanks telling me if all is okay on your side. Do you think 256Mb of swap not enought ? What do you have on your slug ?

Edit : Got my slug freezed check it out
doing top everythings seems Ok just after do ipkg install joe
and slug freeze, need to unplug power, can’t ssh nor WEb interface on it anymore !!!!! but respond to ping
