mbwe-bluering feed and custom firmware

alllexx 17 May 2009 08:02

The feed

I'd like to announce that since recently we have mbwe-bluering-specific feed on nslu2-linux: http://ipkg.nslu2-linux.org/feeds/optware/mbwe-bluering/cross/unstable/
The toolchain was built from WD GPL sourcecode using WD .defconfig with additionally enabled LDSO_RUNPATH support in uclibc and should be fully compatible with MBWE bluering.

Why do we need this? Well, did you ever get 'Segmentation fault' errors or had 'ENOTTY (Inappropriate ioctl for device)' for no apparent reason while using optware packages?..

Ok, before updating the wiki howto this feed should be tested. This is one way to do so:
1. Stop any running optware processes
2. Backup your /opt dir

# tar -czf opt.bak.tar.gz /opt

3. Change ipkg settings to use mbwe-bluering feed:

# sed -i -e s/gumstix1151/mbwe-bluering/ /opt/etc/ipkg.conf

4. Reinstall all currently installed packages:

# ipkg update
# ipkg remove libstdc++ -force-depends
# ipkg install libstdc++
# ipkg -force-reinstall install `ipkg list_installed | awk '{print $1}'`

5. Install some package (like amule) and try it out

That's it for testing. You can always restore your backup if anything goes wrong:

# rm -rf /opt
# tar -C / -xzvf opt.bak.tar.gz

The firmware

bzhou:

For optware, the big obstacle on MBWE is the lack of LDSO_RUNPATH in stock /lib/libuClibc-0.9.28.so
This is becoming more and more annoying as you often need to adjust /etc/ld.so.conf

Here's the custom firmware I made for best optware experience on mbwe-bluering:
ldso-runpath-enabled-firmware

An alternative way to enable LDSO_RUNPATH support:

(This is not recommended for unexpirienced/unskilled people as you can easily brick your MBWE if you mess anything up. And don't forget to make backups! It's been tested to work perfectly on my box, but no guarantee of any kind, though)
1. Shot down your mbwe
2. Remove the HDD(s) from MyBook World Edition (PDF Link) and connect to your linux machine
3. Mount first partition (e.g. /mnt/mbwe1)
4. If you haven't made backups - make them now

# tar -czf /backups/mbwe.lib.bak.tar.gz /mnt/mbwe1/lib

5. Install libs from optware uclibc-opt package to mbwe /lib and unmount

# cd /tmp
# wget http://ipkg.nslu2-linux.org/feeds/optware/mbwe-bluering/cross/unstable/uclibc-opt_0.9.28-1_arm.ipk
# tar -xvf uclibc-opt_0.9.28-1_arm.ipk ./data.tar.gz
# rm -rf opt
# tar -xvzf data.tar.gz
# cp -f opt/lib/* /mnt/mbwe1/lib
# umount /mnt/mbwe1

6. Unplug drive(s) from your machine and plug back to MyBook.

Can we use this feed without changing the uclib and just using ldconfig ?

Re: mbwe-bluering feed

alllexx 17 May 2009 10:59

Yes, we should be able to do so. At least it worked fine on my mbwe at testing time (before enabling LDSO_RUNPATH)

Re: mbwe-bluering feed

alephsmith 17 May 2009 12:00

Great news.

I am also not looking to to update my uclib, mainly cause I don't have the spare sata ports.

Each time I install a new package the cyrus-sasl post install script tries to run:

Configuring cyrus-sasl

Please read the man page of saslauthd and
check settings in /opt/etc/init.d/S52saslauthd 

If you dislike the link /usr/lib/sasl2 -> /opt/lib/sasl2
then you may want to set SASL_PATH instead

Re: mbwe-bluering feed

alllexx 17 May 2009 12:10

Postinstall script seems to be unable to start cyrus_sasl. I guess you should add /opt/lib/sasl2 to /etc/ld.so.conf and run ldconfig.
That's the downside of not having LDSO_RUNPATH - you have to add each and every lib dir to your ld.so.conf.

Re: mbwe-bluering feed

pundy 21 May 2009 04:05

Probably a bit of a stupid question, but it it possible to do this without removing the drives? Or is it a case of removing /lib while running will kill everything?

If I have a two 2 mbw, do I need to do this on both disks?

Re: mbwe-bluering feed and custom firmware

snailium 22 Jul 2009 18:26

Credits to the great work!!!

Just wondering, is anyone interested in moving twonkymedia server to mbwe blue ring?
I know the "white light" edition has twonky installed, but not "blue ring".
Can twonky be integrated in the firmware for "blue ring"?

Re: mbwe-bluering feed

alllexx 17 May 2009 17:19

kevku, alephsmith,
any luck with testing?

Re: mbwe-bluering feed

kevku 17 May 2009 20:35

hmm rtorrent & other stuff seem to work, sb should test ggc & perl. python seems to work.

but for no apparent nfs is acting weird, gonna look into that later. (might not be related to all this) using fw 2.18. seems like some dns issues. hah, i got it, there was no hostname assigned in my router for mbwe so it got stuck when looking for it's name although i have it in /etc/hosts …. go figure ..

Cups seems to be working, however I don't actually have a printer to setup at the moment.

What other packages were not previously working? Happy to test, but honestly I only ever use transmission and mt-daapd.

Re: mbwe-bluering feed

alllexx 18 May 2009 15:25

As far as I know, there were also some issues with amule, gcc and perl.

Re: mbwe-bluering feed

alllexx 18 May 2009 02:17

Note that without enabling LDSO_RUNPATH you may still have some problems due to conflicting stock and optware libs (e.g. with dialog package). A way to solve this without enabling LDSO_RUNPATH is to replace conflicting stock libs (like ncurses with dialog) with optware ones.

moxybooker 20 May 2009 16:31

Can someone please clarify how to fix the LDSO_RUNPATH issue without taking the drive out?

I've tried adding /opt/lib/sasl2 to /etc/ld.so.conf and running ldconfig, but I still get the cyrus-sasl errors every time i install a package.

@alllexx: what do you mean by " replace conflicting stock libs (like ncurses with dialog) with optware ones"?

As you can probably tell, I'm a newbie in the linux space.

Thanks!!!!

Re: mbwe-bluering feed

alllexx 20 May 2009 18:15

Well, you can't actually 'fix' LDSO_RUNPATH issue without taking the drive out (not at this point, at least, - perhaps, we need a custom firmware?.. I tried to make one already but only bricked my drive once; if only I had more spare time…). You'll have to add every directory that contains shared libs to ld.so.conf and use ldconfig as a workaround
The other problem I mentioned is that without LDSO_RUNPATH if you have some library (like libncurses.so) in a system lib dir (like /lib /usr/lib) and in optware lib dir, the stock one is loaded when a program is started. And this meens we can have some errors with optware packages.
A way to solve this may be replacing stock lib with optware one, but you can potentially break something, so better avoid doing this if possible. Seems to work fine with ncurses, though.

Regarding cyrus-sasl, this is not an LDSO_RUNPATH issue. This should fix the problem:

# killall saslauthd
# ipkg install cyrus-sasl -force-reinstall

Re: mbwe-bluering feed

I've managed to create a custom firmware, arter all, so you can fix LDSO_RUNPATH issue without taking the drive(s) out now. Looke here for instructions.

Re: mbwe-bluering feed

kevku 21 May 2009 15:25

wow you compiled it all from source, used the patched buildroot? gotta give you some credit then :P

Re: mbwe-bluering feed

alllexx 21 May 2009 18:27

Thanks, it really was some effort, but I've been gaining the skill to do this for last couple months "little by little" :D. Actually, I also had to use wdgxnc-02.00.18.wdg rootfs.ext2 image as some things (like certain init scripts and damn mionet) are not available even from patched buildroot - that's why I bricked my box the first time.

Re: mbwe-bluering feed

alllexx 21 May 2009 19:31

Hm, there seem to be some problems with the FW: for some reason temperature monitoring scripts don't work right, so I had to use alternative ones.
Better wait a bit till I fix this :P

UPD: On the other hand, feel free to use this howto to fix this yourself after installing the FW

OK, v2 firmware is ready. Added gcc, used hdparm v9.15 and temperature monitor scripts by kyyhkynen.

Big11 25 May 2009 15:25

Hello to all

First: Sorry for my english but it is not my native language.

Second:
How can i install optware with the new feeds as decribed, on my MBWE-blueRings ?

can i do that is in the installation Guide - second option: "Alternatively, run following commands one by one:"
replacing the Path of the "gumstick" packages with the new "mbwe-bluering" ?

thanks a lot for your support

Big11

Re: mbwe-bluering feed

alllexx 25 May 2009 16:47

Hi, Big11
Sure, you can, and you can also do this:

# wget http://mybookworld.wikidot.com/local--files/optware/setup-optware.sh
# sh setup-optware.sh
# sed -i -e s/gumstix1151/mbwe-bluering/ /opt/etc/ipkg.conf

The feed is more or less tested now, but before updating the howto it would be nice to have more people test the ldso-enabled firmware to mention it there too.

Cheers,
Alex

Re: mbwe-bluering feed

alllexx 25 May 2009 16:59

I'm going to release a v3 FW sometime soon, in a few days time, where I've added some more kernel modules, restored NFS, XFS,.. Also, configured upgrade script to preserve some settings (such as /etc/lighttpd/lighttpd.conf, /etc/hosts.allow, /etc/hosts.deny, /etc/exports).
Any feedback on the FW is much appriciated and if you have any feature requests, post them here please.

Thanks for your interest,
Alex

Re: mbwe-bluering feed

kevku 26 May 2009 11:19

I would like to see ipv6, sit, and loop modules. Also in nfs maybe increase the max block size to 64k? (NFSSVC_MAXBLKSIZE in /include/linux/nfsd/const.h) although I'm not sure about the effects of this … :P

Re: mbwe-bluering feed

alllexx 26 May 2009 11:56

Already added idv6 modules :P
Will add sit and loop. I don't know about nfs max block size, as I'm no expert in this at all, so until someone knowledgable verifies it's safe, we'll hold back on it.

Re: mbwe-bluering feed

Big11 28 May 2009 08:47

Hello alllexx!

Thx for your information. Question: where can i find the "new" firmware V2 and some more informations about.

Any chance to get also WOL (WakeOnLan) in the new "Firmware" V3 ?

should i wait a couple of days till release of V3 ? or would it takes longer ??

Big11

Re: mbwe-bluering feed

alllexx 29 May 2009 04:08

Hello, Big11
You can get FW v2 on the firmware page - a link here - "1. Download firmware as firmware.sh to your public share root" points to the latest firmware. The v3 is complete, but I encountered some problems with ipv6 module, so I recompiled modules without disabling Leon chip support in the kernel to see whether it helps, and just don't have the time to test know. Most likely, it will be released on the weekend.

Regarding WOL support, it's not enabled by default and I haven't got the slightest idea how to enable it (or if it's possible at all) - there's no BIOS in MBWE for you…

Cheers,
Alex

Re: mbwe-bluering feed

Big11 19 Aug 2009 09:16

Hi Alex

IMHO isn't WOL just a parameter compiling the Network interface into the kernel ?
i think i read that in another forum…

are you able to check that ?
it would be a great benfit for a lot, i suggest

thx
Big11

Re: mbwe-bluering feed

alllexx 26 May 2009 15:18

Seems like loop is built-in into the kernel and sit is compiled into the ipv6 module

UPD: I also enabled writing support in the ntfs module - we'll see whether it works or not

ntfs-3g?

Re: mbwe-bluering feed

alllexx 26 May 2009 15:54

No, I tried it a couple of months ago using optware and it didn't work, even though I had the needed fuse module

Re: mbwe-bluering feed

alllexx 29 May 2009 18:05

Hm, it seems that to add ipv6 you have to update kernel image as well, otherwise you get something like this

Re: mbwe-bluering feed

alllexx 30 May 2009 20:36

Ok, v3 released

Cheers!

Re: mbwe-bluering feed

alephsmith 01 Jun 2009 07:19

Testing now.

Upgrade worked without issue.

ntfs write support seems to work fine. Mounted the disk manually using fuse, but how do I get it to mount using fuse automagically when it gets plugged in. I assume it involves playing with fstab. But does anyone want to hold my hand so I don't brick something?

Re: mbwe-bluering feed

alllexx 01 Jun 2009 10:45

Just found a way to do it nice:)

# ipkg install util-linux-ng
# rm /bin/mount /bin/umount
# cp /opt/bin/util-linux-ng-mount /bin/mount
# cp /opt/bin/util-linux-ng-umount /bin/umount
# ln -s /opt/bin/ntfs-3g /sbin/mount.ntfs-3g

Then use this guide to edit /etc/fstab.
To make any ntfs volume be mounted using ntfs-3g (i.e. by simply running `mount /dev/sdc1 /mnt/usb`) you can do this:

# ln -s /sbin/mount.ntfs-3g /sbin/mount.ntfs

P.S. Unfortunately, the speed is really low, less then 1 mb/sec, due to weak CPU :(

Re: mbwe-bluering feed

alephsmith 01 Jun 2009 12:07

Cool, thought I think I may leave it.

It is good just having the ability to write to ntfs if necessary. Most of my drives are ext/hfs so ntfs support is just a nice-to-have.

For future versions can you retain settings in mDNSResponderPosix or comment out the necessary lines in update_network_config.sh as described here: http://mybookworld.wikidot.com/forum/t-106007/netatalk-tutorial .

Thanks for you hard work, will report back any issues that I notice.

Re: mbwe-bluering feed

alllexx 01 Jun 2009 16:44

To keep mDNSResponderPosix actual instead of commenting out lines in update_network_config.sh we can do the followong:

# Write a new mDNS responder config file
echo "\"$current_hostname user if\"" > $mDNSconfig
echo "_http._tcp. local" >> $mDNSconfig
echo "80" >> $mDNSconfig
echo "$current_hostname file server user interface" >> $mDNSconfig
for FILE in `ls ${mDNSconfig}.d 2>/dev/null`
do
if [ -f ${mDNSconfig}.d/${FILE} ] ; then
        cat ${mDNSconfig}.d/${FILE} >> ${mDNSconfig}
fi
done

Then you just need to create /etc/mDNSResponderPosix.d folder and store all your additional settings there, e.g., /etc/mDNSResponderPosix.d/AFP file

MyBookWorld AFP
_afpovertcp._tcp. local
548
MyBookWorld AFP server

And I'll just tune upgrade script to preserve /etc/mDNSResponderPosix.d folder at upgrade time

Another directory to maintain: /root/.config/transmission-daemon/

Not necessary, but would be good for future upgrades.

Now if only transmission would stop crashing on me :(

Re: mbwe-bluering feed

alllexx 07 Jun 2009 07:01

The same idea crossed my mind after installing transmission just a couple of hours ago ;)

Now if only transmission would stop crashing on me :(

It's some sort of a libevent-related bug: http://trac.transmissionbt.com/ticket/2078

Hi alllexx, sorry for not being specific. I was logged in with my putty, and i keep it opened. Then when I try to access my webserver, the putty window showed that " sudo: must be setuid root " message. I mean when I try to open a page or refresh a page, it keeps showing that message one after another.

I'm just clueless, any help would be great, thank you.

Re: mbwe-bluering feed

alllexx 01 Jun 2009 19:05

Ok, it's not a big deal.
The problem is that your /etc/sudoers was reset to FW default. Just restore it from your backups.
You most likely miss a record (or two) like

    /shares/internal/PUBLIC/WWW/Admin/SetWebUser.sh,\

Re: mbwe-bluering feed

gameboyy 02 Jun 2009 05:06

cool, that does the job, however, there are one more thing i forgot to mention after installed v3 mykernel firmware. the Big power button which used to shutdown the device by press and hold for a few second, now it doesn't work anymore. When I hold it for a few second, it just blinds a couple and stop,, the device kept runing. Another strange thing is that the Ethernet connection speed indicator on the admin page is now displaying a question mark(?) , it used to show 1000mb.

Any idea? thanks again

Re: mbwe-bluering feed

alllexx 02 Jun 2009 06:35

Yes, now that you mention it, my MBWE ignores the power button as well. Must be due to the custom kernel, and that's odd, as I didn't disable Leon chip support, which should be responsible for this. Currently, no idea how to fix this, can only suggest to use the official kernel if you need the button more than ipv6/ipip modules. Sorry about this…
Regarding the connection speed indicator, I guess we can safely ignore this.

Alex

Re: mbwe-bluering feed

gameboyy 02 Jun 2009 18:08

Actually, I remember before v3, installed v2, which i believe is the official kernel, the power button wasn't working either, so something must be screwed.

Gameboyy

Re: mbwe-bluering feed

alllexx 02 Jun 2009 18:28

I'm positively sure that power button worked fine with v2. I also discovered that I did mess up with kernel configuration a little. I'm rebuilding the kernel now.

Thanks for noticing this issue,

Does anyone have a copy of the original etc/sudoers file.

The backup I did of my system config didn't contain one originally, so I have nothing to restore, hower I'm still getting the "sudo: must be setuid root" error. Also visudo does not work. Is it OK to edit this file with nano?
