HOWTO install debian on 128 mb usb stick

install debian on a usb stick

Setup good firmware

I used phedny's custom firmware (1.9.2.7-3b) with ipv6 support, you can download it here. Howto install new firmware is described in other howto's on the wl500g forums.

If you don't want ipv6, you can skip setting it up. But hey, why not use ipv6 when I included all kinds of neat ipv6 things like radvd, iproute2, ping6 and traceroute6! Well, read howto setup your wl500g as a ipv6 router

I disabled the stupid-ftp server, because it's .. to simple. Why not use a cool ftpd server when you have a working debian installation? :-) If you have disabled the ftp server on the admin webpages, the usb-storage modules won't be loaded into the kernel. Make sure you have loaded the required modules into the kernel:

Code:

insmod /lib/modules/2.4.20/kernel/drivers/scsi/scsi_mod.o insmod /lib/modules/2.4.20/kernel/drivers/scsi/sd_mod.o insmod /lib/modules/2.4.20/kernel/drivers/usb/storage/usb-storage.o

Download the image and store it on the usb memory stick:

Code:

wget -O /dev/scsi/host0/bus0/target0/lun0/disc http://masteen2.iiivx.net/wl500g/debian/debian-sarge-128mb-mipsel.image

this image includes a partition table and stuff, because the ipv6 firmware doesn't have e2fsprogs out of the box. Mount the crazy thing so you can start messing around.

Code:

mount /dev/scsi/host0/bus0/target0/lun0/part1 /tmp/harddisk

Get into your debian installation.

Code:

chroot /tmp/harddisk/debian-distro /bin/bash mount -t proc none /proc mount -t devfs devfs /dev swapon /dev/scsi/host0/bus0/target0/lun0/part2

Generate your own key's and start dropbear

Code:

rm /etc/dropbear/dropbear_rsa_host_key && rm /etc/dropbear/dropbear_dss_host_key dropbearkey -t rsa -f /etc/dropbear/dropbear_rsa_host_key dropbearkey -t dss -f /etc/dropbear/dropbear_dss_host_key /etc/init.d/dropbear start

Use your fresh debian installation

Now the second part, using your debian installation!

Ssh to your router using the account 'normaluser' and the default password 'userpasswd'. Change your password and type 'su', the default root password is 'rootpasswd'.

Do something kinky like

Code:

apt-get update; apt-get dist-upgrade

And enjoy! Don't forget to regulary clean up the useless stuff I mentioned before.

Additional information

Example of how things can look when everything goes okay

Code:

Feanor:~ iiivx$ ssh normaluser@192.168.1.1 normaluser@192.168.1.1's password: Debian GNU/Linux comes with ABSOLUTELY NO WARRANTY, to the extent permitted by applicable law. normaluser@wl500g-router:~$ su Password: wl500g-router:/home/normaluser# uptime 21:08:10 up 2 days, 8:38, 1 user, load average: 0.29, 0.36, 0.69 wl500g-router:/home/normaluser# uname -a Linux wl500g-router 2.4.20 #57 Thu Feb 10 14:29:29 CET 2005 mips GNU/Linux wl500g-router:/home/normaluser# cat /etc/debian_version 3.1 wl500g-router:/home/normaluser#

How did I make this? How can this work?

Indeed, "cdebootstrap -amipsel sarge debian-distro http://ftp.de.debian.org/debian" creates a 100 megabyte filetree, and if you unpack the stuff it gets even worse. So I decided to delete all the 'useless' crap.

The first reduction technique is to remove the documentation from the root filesystem. They include the Perl .pod files and everything under the following directories:

Code:

/usr/doc /usr/info /usr/man /usr/share/doc /usr/share/info /usr/share/man

Two others that should either be trimmed or eliminated are . . .

Code:

/usr/share/locale /usr/share/zoneinfo

/usr/share/locale provides locale information, so that users can see the system in their own languages, currency formats, etc. /usr/share/zoneinfo provides timezone definitions, so that users can see local time and perform timezone conversions. Both of these could certainly be trimmed down -- a server which is going to be administered by a single person does not need locale information for languages that person does not speak; and a server which will be used in one place, and does not do complex time-related applications (e.g. calendaring) will never use more than one timezone definitions.

However, removing all of the documentation, the locale, and timezone information only reduces the size of the Debian root filesystem that much, so I also deleted a bunch of not-required libraries and packages. If you miss them, you can install them using apt-get(8).

I ended up using this packages list: debian-sarge-128mb-mipsel-packages.txt

output of my df -h & free -m

Code:

root@wl500g-router:/# df -h Filesystem Size Used Avail Use% Mounted on /dev/scsi/host0/bus0/target0/lun0/part1 112M 78M 29M 74% / root@wl500g-router:/# free -m total used free shared buffers cached Mem: 13 12 1 0 0 5 -/+ buffers/cache: 6 7 Swap: 10 1 9 root@wl500g-router:/#

Just to let you know: 1.9.2.7-4 includes ipv6 and has fdisk and e2fsprogs.
So, it's better to pack your image as tar.gz and include an info on partitioning disks to the how-to, as even 128MB flash drives could be different.

I am aware of the fact that this howto isn't capable of handling slightly different setups. As soon as I have time to test 1.9.2.7-4, I will update the howto and include information on partitioning the stick and tarball's.

Great stuff... but I have a conundrum.

I can see usbdevfs:

[admin@mouser root]$ ls /proc/bus/usb/
001 devices drivers

But usbdevfs doesn't seem to appear in the chrooted environment:

[admin@mouser admin]$ ls /tmp/harddisk/debian-distro/proc/bus/
pci usb
[admin@mouser admin]$ ls /tmp/harddisk/debian-distro/proc/bus/usb/
[admin@mouser admin]$

Do you have any suggestions as to how I can execute the Debian software
and access usbdevfs?

edit: someone on #wrt54g suggested -obind with mount, which seems to have done the trick.

Indeed, either way you can mount /proc and /dev from within the chrooted enviroment, or perform a binded mount. I'm glad you liked this :-)

Hi iiivx,
I am a bit lazy with cleaning, so I would like to take a 1024MB USB stick, but the cdebootstrap command failes with "E: Couldn't install root!" after extracting the last package. What is going wrong?

Darkstar.

Darkstar.

The cdebootstrap command is expected to fail, since you aren't bootstrapping on a mipsel machine. Thus it cannot execute the binaries it want's to execute. Read the tutorial on the wiki, it should help you enough to get something up and running.

Ok, got this. But I have another question: Is it possible to boot into the Debian distribution in order to start the desired services via the /etc/rcX.d/... framework?

Unfortunately the wiki is not acessible right now?! I really would like to try the debian on the wl500g...
Do you still plan to post an image of debian without the partition table ? :o

What can you do exactly with it? Can in the chrooted environment thttpd and mysql be run? mysql seems to be avaible in debian mipsel package....

Thanks for your help.

Hello
Thanks for the great tutorial. It worked fine for me.
But now i have a little problem:
after "apt-get update; apt-get dist-upgrade" i have very little space left for other packages. So is there a way to resize the image???
I use a 6GB Harddisk and Olegs Firmware 1.9.2.7-6b.

If you attach your USB device to a PC, you can use Partition Magic for that or otherwise Ranish Partition Manager.

Kleinertuerke

Hello
Thanks for your answer Styno. Partition Magic is telling me that the harddisk is defectiv :confused: and i cant do anything except creating a new partition.
iiivx wrote that the image includes a partiton table. Is there no easy way to change that?? I guess i should ask google ;)

I installed Debian onto a 256MB USB disk, everything is working great.
The output of 'df -h' is as follows:

root@Asus:/# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/scsi/host0/bus0/target0/lun0/part1
112M 78M 29M 74% /
root@Asus:/#

What I understand from this is that only half of the size of my USB disk is used.
Is it possible to extend the size of this partition to use every available space that is still on the USB disk? If so, how can I do this?

Regards,

Molski

nerodark

styno, i tried, partition magic and ranish partition manager, and both wouldn't detect my usb key (if they do it is really hard to find the option to show the partitions on my usb key)

i had the same problem than most of you: i have a 512MB usb key and when i tried to install debian on it, it created something like a 120MB partition (linux ext3) and a 15MB partition (linux swap2)

i recommend you use Paragon Partition Manager to do the following steps to resize the partition (you have to get the FULL VERSION ONLY to unlock limited features)

using paragon you will see something like (i will use this example during this little tutorial), it must look like this because the debian installation created this special partition table designed for a 128MB usb key:
[--------120MB(ext3)--------][---15MB(swap2)---][----------unallocated space(369MB)----------] = ~512MB

1- you will see there is a lot of free space after the swap partition, the first thing you would probably do, instinctively, is delete the swap partition (because you think it doesnt contain any data and wont hurt the debian installation), then resize the ext3 and recreate a swap space. well no, you must not do that.

2- first you have to play with the current swap space: set the free space after to 0MB and the free space before to 389MB (according to the example, still do it based on the size of your usb memory key). then resize the ext3 partition to the maximum allowed based on your unallocated free space.

[--------120MB(ext3)--------][----------unallocated space(369MB)----------][---15MB(swap2)---] = ~512MB

[------------------470MB(ext3)------------------][---15MB(swap2)---] = ~512MB

3- apply the changes, reboot your computer (if necessary), now you are safe to remove the usb key, plug it in your asus router, reboot your router to load, mount, and then you are good

NOTE: if Paragon Partition Manager tells you that it cannot proceed to apply the changes because the usb memory key is used by another program (in other words, it is already in used by Windows itself because it loaded the driver for it to be browsable), simply reboot your computer, do not unplug the usb key leave it in the slot, paragon will lauch the task to apply the changes before windows start loading his drivers

Hi!
I had the same problem.
Solved it this way under RH:

1) Install the image on the USB-stick as described.
2) Open a terminal and make the following steps:

#Dump the image onto your harddisk
dd if=/dev/sda1 of=/path_where_to_store_dumpfile/file bs=512

#Run fdisk, delete all existing partitions, create resized partitions
#In my case 196Mb Linux and 32Mb Linux swap
#sda=usbdevice

fdisk /dev/sda

#copy back image

dd if=/path_where_to_store_dumpfile/file of=/dev/sda1 bs=512

# run e2fsck t check the partition

e2fsck -f /dev/sda1

#resize filesystem

resize2fs -p /dev/sda1

This worked fine for me.

Hope that helps

Need help booting Debian from USB-Stick

Sorry for my bad english...

Im trying to boot from a Debian Sarge installation on an external memory-stick.

I installed debian and it works great when I use chroot.

I set the memory-stick as boot-device:

Code:

nvram set boot_dev="/dev/scsi/host0/bus0/target0/lun0/part1" nvram commit

When I reboot the system boots from memory-stick. The light on the stick is flashing and the system is not reachable.

I'm pretty sure the debian-configuration is incomplete. This is what I configured:

/etc/fstab

Code:

/proc /proc proc defaults devfs /dev devfs rw 0 0 /dev/scsi/host0/bus0/target0/lun0/part1 / ext3 rw 0 0 /dev/scsi/host0/bus0/target0/lun0/part2 none swap sw 0 0

/etc/network/interfaces

Code:

auto lo iface lo inet loopback auto vlan0 iface vlan0 inet static pre-up ifconfig eth0 up pre-up vconfig add eth0 0 address 10.1.1.12 netmask 255.255.255.0 gateway 10.1.1.10

I have not yet added an ssh-server to the init-scripts since not even ping to 10.1.1.12 works.

Is there a kernel-module missing? If yes, can I copy the modules from flash and add a line to /etc/modules?

I have no serial-console available. So it's very hard to find the problem. Please help me!

Many thanks

Hello,

I tried the method in the wiki to install Debian.

But after i have the skeleton in /tmp/harddisk/debian-distro (i made it on a Debian PC with cdebootstrap).

When i do chroot /tmp/harddisk/debian-distro /bin/sh everything is ok
but after that any mount command give me the message "Illegal instruction"

Code:

[admin@routeur debian-distro]$ chroot . /bin/sh [root@routeur /]$ mount -t proc none /proc Illegal instruction [root@routeur /]$

Ok, i found all of my problems, my USB key was a data corruptor, so i changed it. And know everything works fine :cool:

I installed debian with cdebootstrap, and inside it i have only dropbear and samba installed so when i telnet the router i get in Oleg's Linux and when i ssh it i get in the debian realm.

The USB key is mounted in /opt in that example.

Here is my /usr/local/sbin/post-boot if it can help

Code:

#!/bin/sh insmod scsi_mod && insmod sd_mod && insmod usb-storage mount -t ext3 -o rw,noatime /dev/discs/disc0/part1 /opt swapon /dev/discs/disc0/part2 if [ -d /opt/debian-distro ]; then chroot /opt/debian-distro /etc/rc.asus fi

And the /opt/debian-distro/etc/rc.asus that i made and chmodded a+x

Code:

#!/bin/sh mount -t proc none /proc mount -t devfs devfs /dev invoke-rc.d rc 5

First it mounts the proc & dev and then it launch the installed services by switching to runlevel 5. That way everything is launched in a neat manner (even if it launches cron and inetd that i don't need).

If you run the script manually you would see somthing like this

Code:

Starting Dropbear SSH server: Starting internet superserver: inetd. Starting Samba daemons: nmbd smbd. Starting periodic command scheduler: cron.

And after 4 nights of searching i finally have samba 3.0.14 running on my WL500G Deluxe. :)

Thanks to everyone inhere :) i finally got i working!!

Created my own cdebootstrap, and took it from there.. now the router is running web/php/mysql/samba server, and all is working perfectly! :D

:edit
Forgot to tell that it is running on a 512 mb usbkey, Not the fastest thing in the world.. but it get's the job done ;)

Booting Debian from USB

I'm trying to boot Debian from a USB flash drive on my Asus WL500gP. Does anyone know if I'm attempting the impossible? I've search high and low in this and other forums and haven't found any details on doing this successfully. If I missed something obvious, please tell me - I'll gladly accept feeling stupid in exchange for an answer :)

According to this site: http://wiki.debian.org/DebianWRT
Under the "What Works Now" section, you can use Oleg's firmware to "actually boot Debian".

I followed the directions on http://wl500g.dyndns.org/ under the "Root file system on the external USB drive" section, with the exception of step 2. I did fdisk, and format the drive for ext3, but didn't copy Oleg's root fs like this:

Code:

# copy everything tar cvO -C / .version bin/ etc/ lib/ sbin/ usr/ www/ var/ | tar x -C /mnt # create required dirs mkdir -p /mnt/tmp && mkdir -p /mnt/dev && mkdir -p /mnt/proc && mkdir -p /mnt/mnt

Instead, I copied a working Debian system onto the drive using the instructions here: http://wiki.wl500g.info/index.php/Debian%20Distribution
Specifically I did this:
#

Code:

1.1 Steps on PC with Debian (sarge) * Create debian-distro directory on PC which will contain the distribution. * cdebootstrap -amipsel sarge debian-distro http://ftp.de.debian.org/debian * That will fail after a while leaving you with a skeleton. * Copy entire directory tree to the Asus harddisk, e.g. /tmp/harddisk/distributions/debian. # 1.2 Steps on Asus * ssh to your Asus device * change to debian directory ? where is debian directory? , e.g. /tmp/harddisk/distributions/debian? * create etc/fstab hosts resolv.conf apt/sources.list * chroot /tmp/harddisk/distributions/debian /bin/sh o (The first three steps are only needed if you need swap space, wl500g needs it) o mkdir /swap o dd if=/dev/zero of=/swap/16Mb bs=1024 count=17000 o mkswap /swap/16Mb o swapon /swap/16Mb o mount -t proc none /proc o mount -t devfs devfs /dev o cd /var/cache/apt/archives/ (if there are no packages here, try also /var/cache/cdebootstrap/ and /var/cache/bootstrap) o dpkg --force-all -i libc6*deb o dpkg --force-all -i dpkg*deb o dpkg --force-all -i libc6*deb o dpkg -iGREB . (repeat this step until the number of errors have stabilized, most likely at zero) o check remaining dpkg errors if any o /usr/sbin/base-config * you have now an entire Debian installation (incl. apt-get etc.)

Now I'm not sure if those directions were supposed to be for just setting up Debian to be used in a chroot jail, but I couldn't find any other instructions for setting it up so that's what I did.

I can mount the flash drive and chroot to it and run the Debian binaries just fine, including apt-get to download new packages (as a test I used apt-get to download lynx and it worked fine). However, what I'd REALLY like to do is not chroot it, but actually boot from it.

So I did this:

Code:

nvram set boot_dev="/dev/scsi/host0/bus0/target0/lun0/part1" nvram commit

and rebooted and watched as the router made the LED on my flash drive blink a lot (seemingly indicating that it was booting from the flash drive). But even after waiting for the activity light on the flash drive to settle down, I'm unable to get ping responses from the router.

So my question is: is the router not able to boot this Debian drive that I set up, or is maybe the problem just that the network isn't coming up right after it boots Debian?

some progress...

I made some progress in figuring out what the problem is, although I haven't been able to fix it yet. I thought maybe some people would be interested to hear what I've found out so far.

Instead of continuing to stumble around in the dark I decided to try getting a console so that I could see some startup messages while the router boots.

To get a serial port, I basically did what is described in this thread:
http://wl500g.info/showthread.php?t=...ght=add+serial

I didn't find any threads talking about adding a serial port to the 500gP, but it's basically the same as how that thread describes it for the 500gx. The main difference that I had to deal with was that there are no headers on the board for the UART on the 500gP so I had to solder those in myself. In the thread for the 500gx some people said they were able to add the serial port without even taking out all the screws on the casing - preserving their warranty sticker.... not possible with the 500gP. If you can solder in headers onto the PCB without removing all the screws then you must be a soldering god.

Anyway, once I got a serial port on UART0 and hooked up my computer, I was able to read the boot messages when it tries booting from my USB stick with Debian on it.

After that last message the system just hangs there. After 5 minutes it repeats the messages at the end that start with "INIT", but that's all.

So, we can see that it started booting from the USB stick, but kept getting "segmentation fault", which may have led to the hang up at the end. Another time when I tried booting I got something slightly different. Instead of a bunch of "segmentation fault" messages, I got a bunch of "bus error" messages.

Both of these messages seemed to indicate to me that maybe there was something wrong with my USB stick, so I tried the whole process again with an external USB harddrive instead. Unfortunately I got the same thing.

Any suggestions?

I also try to put Debian on my wl-hdd. So this looks quite interestining to me.

What 'bout the kernel? Is it from Debian or is it that from Asus/Oleg?

I guess there are some problems with the usb driver

some reverse-progress

The past several weeks I've been taking a break from trying to get this to work, but it was just a break - I haven't given up completely yet.

I feel like I do need to post an update as to what I've been able to get working so far because my past post was somewhat misleading...

I said that I was able to get Debian working properly in a chroot jail and that I could use apt-get to install packages. That is true, but I had posted that before trying to use Debian from within that chroot jail for a while.

I got to a point where I was going to give up on trying to get it to boot and just use it from the chroot jail, but after installing a few packages with apt-get, I started getting those same "bus error" and "segmentation fault" messages that I would get when trying to boot! I would get them whenever I tried running any command, including just "ls". Sooo, I can't say that I've gotten it working 100% from chrooting it, since the amount of time that it works is limited. I'm not sure if it's really a time issue or if it's the result of installing certain packages with apt-get. :confused:

I'll post more info as I figure it out. If there's anyone out there who has gotten debian to run successfully on their asus router, please post here and let me know. In particular, I'd be interested in the exact model of router that you're using, as well as the steps you took in getting debian to run.

did you resolve it?

I am also going downt his path...did you have any luck? I am running debian within chroot. I followed this:
http://wpkg.org/index.php/Running_De...luxe#Downloads

but i couldnt get the custom 2.6 firmware to boot so i am stuck with the chroot...eeek...

still plagued by "bus error"

Thanks for the link - I tried the firmware and base system that was provided there, but STILL got a ton of bus errors! I'm starting to think that my router is just broken. :(

I think if I didn't get the bus errors than everything would be working fine because the router did manage to boot up, but it's certainly not usable with all the bus error's that it got.

What firmware are you using to chroot to debian?
Have you ever gotten any of these "Bus error" warnings?
Are you using the asus premium or deluxe model?

If you're trying to use an external USB harddrive instead of a USB stick that may be the reason why you aren't able to boot with that openwrt firmware given in the link - when I tried that firmware with my external usb harddrive it wouldn't detect it (oleg's firmware does), but it would detect my usb flash drive.

Below is a paste of what I got from my serial console while booting the router with the firmware and base system provided in the link.

Now, you can run Debian on both WL-500G Deluxe and WL-500G Premium - I corrected the firmware on http://wpkg.org/index.php/Running_De...WL-500G_deluxe

mangoo: Your approach to debian looks very interesting, since I am currently building my WL-500gx with OpenWrt Kamikaze 2.6 kernel, and there are some problems with it...

Does debian on a 2.6 kernel support the bcm43xx driver? Is it working?
Compared to OpenWrt: http://forum.openwrt.org/viewtopic.php?id=7842

If everything is stable with debian, I'd switch immediatly :-)

Debian on Premium

Hi

I want to run debian on wl-500gP.
I followed this instructions http://wpkg.org/index.php/Running_De...WL-500G_deluxe
but after I flash "openwrt-brcm-2.6-jffs2-128k.trx" image to my box I cant telnet to my router. Also I can't ping it. Power and LAN led are on.

TNX in advance Jure, Slovenia

I think, you need write Debian into your USB drive (flash or HDD), and make network configure (steps 2 and 3 in wiki). And may-be you need connect to your router via SSH (not telnet).

You should get a serial port hooked up so you can see what's going on. There could be a large number of reasons that it isn't working.

Latest update:

This whole time I had been using my WL-500gPremium with the 32MB RAM expansion trick:

Code:

nvram set sdram_init=0x0008 nvram set sdram_ncdl=0 nvram commit reboot

After finding out that the "Bus error" messages that I kept getting were probably coming from the kernel trying to use memory that didn't exist, I decided to set the memory back to just using 16MB:

Code:

nvram set sdram_init=0x000b nvram set sdram_ncdl=0 nvram commit reboot

And ever since doing that I haven't gotten a single "Bus error" message again - everything has been working quite well (except for the fact that I'm now running on just 16MB :( )

1.) What do these values that I'm setting to sdram_init mean exactly!? I found http://wl500g.dyndns.org/sdram.html , but does that apply to the WL500gP?

2.) Has anyone else had trouble after enabling the full 32MB on their premium box?

3.) Is it possible that there could be something physically wrong with one of the chips on my board?

4.) I don't remember ever changing my sdram_config. It's currently set to 0x0062 - what's everyone else's set to?
