But did it re-mount the root filesystem in read-only mode? Have a look at the dmesg output.

I had issues with harddisk too. This is why I had to make frequent backup of image and erase my harddisk.
This is propably when slug gets too hot or something and some writes to disk fail and corrupt filesystem.
This is not a issue with image..

I made a simple udev rule that sets led2 on (or where these reversed in this version of openslug?) when sdb exists as far as I remember..

And what comes to openslug.. It runs fine on machine without requiring microcode file, but as I stated, it has some other kind of system to load up network. And since gentooslug and other systems for slug started to appear, there's plans for openslug/slugos4, to help fix these problems. I've been trying to reach nslu2-linux's devs as I earlier mentioned, about how openslug loads up microcode and so on, but yet no one has answered to this.

If someone is able to make a image which works with newer nslu2's.. Please, don't make any other changes..
And create a backup of image and host it somewhere where I can grab it.. I'll put it on the website then for people who have newer slugs..

I am getting suspicious kernel messages on my slug:

Wow, php (including cli) took over 8h to merge!

Although I've just had another brain fudge from the NSLU2 whilst trying to emerge rrdtool.....weird and pointlessly stupid but the NSLU2 seems happier emerging at night! Maybe its shy or something

It may be that I have managed to solve my problems. I have copied the alias declaration from OpenSlug and this one works. My interface boots nicely as eth0. Unfortunately I do not have copies of my older aliases so I can't say what was wrong. I also had to switch the network module from iproute2 to ifconfig in /etc/conf.d/net. This might be because I have downgraded the image to stable arm in the meantime.

Weirdly, I do not have the loopback device any more. This may be a problem at certain point. When I try to start it manually I get a message that

Hi,

I've experienced problems with my slug in compile-situations ( with or without ccache/distcc ) and thought of the same things:
overheated cpu, problems with my usb-enclosure and so on.... all because I started with an de-underclocked slug.

but after some try-and-error i found out that my slug does not like swap-partitions greater than 512MB.

reproducible after adding more than 512MB swap my slug crashed.

Don't know if this could be your problem, since my slug is not running atm.

People are trying to download gentooslug from my server, unfortunately I was supposed to re-install my server..

I just forgot that I had ALL my backups mounted under /tmp/mnt when I was in /tmp and wrote

try undeleting with newest midnight-commander.
if the data hasn't been overwritten, it could work.
it is located under commands

Folks:

A kind soul provided me a copy of Jake's latest gentooslug this morning, and I have it up and running, "emerge sync" -ing as I type this.

I too struggled with the net initialization, but all it took to get things working were:

- Setting up my config for eth2 in /etc/conf.d/net
- symlinking net.eth2 to net.lo
- adding net.eth2 to the default runlevel

FWIW, I switched over to openssh (already installed), and it -just works-, so I have no idea if dropbear will work. As an aside, for all who choose to run Jakes image and openssh, I recommend you zap the keys which are in /etc/ssh and restart the openssh sshd so that it regen's unique keys for YOUR slug.


Thanks....

Greetings:

If you've been reading recently, I have been in the process of moving my slug from the uclibc based "standard" gentoo build to one based on Jake's glibc build.

I'm up and running now, with a working cross compiler and everything.

Just for background, the old uclibc build was on an old external disc, Jakes went onto a new one.

So, this is where it gets interesting....

With the NEW disk connected to the slug's Disk1 port, I booted the glibc image. I then connected the OLD disk to the slug's Disk2 port. The slug froze after a couple of seconds. Hmm.... cosmic rays, methinks...

SO I do it again, this time while tailing syslog. I see the disk insertion in the logs, and then it froze again.

SO, I power off and restart with both connected, thinking the kernel will sort them out at boot. It does, but it booted off the OLD disk, and detected the NEW one, still connected to disk2 as sdb. I remember some discussion of reversal of LED1 and LED2, and I though to myself, maybe something is "cross-wired" in the kernal causing this.....

SO, I shut it down, reconnected the disks this time with OLD on Disk1, and NEW on Disk2. It STILL boots off of the OLD disk, detects it as sda, and detects the new one as sdb.

I thought that usb disks (like scsi's) were labeled in order of detection / insertion. That's obviously not what's going on here.....

Both disks have " / " on sda1, " <swap> " on sda2. Both roots are formatted with ext3. Neither have volume labels assigned.

On the other hand, I have inserted and removed usb flash drives into the Disc2 port of both of these builds, and they were (correctly?) detected as sdb....


Can anyone offer any insight?



Confused.....

This kind of through me for a loop, I thought my networking wasn't working, but sure enough it was. My slug when booted into Gentoo doens't respong to broadcast pings. Openslug by itself does, and that's how I was finding it on my network since I'm on DHCP. Had to pull the IP out of the DHCP server to find out where my gentoo slug ended up. Anyone know how to turn on responding to broadcast?

OK, life is pretty good.... I've been up and running for quite some time, with very few issues.

I believe that the USB drive confusion I posted about earlier is an OpenSlug thing. When you run turnup from openslug, it apparently "grabs" the unique ID from the named drive and stores it somewhere persistently as the root drive. As I was recycling a drive I had previously used as a second drive, this was apparently confusing the poor little slug, or at least its openslug personality.

zapping the drive and reformatting it seemed to have cleared it up, although I would really like to understand how this is really working, and where the unique IDs are getting stored.

On another note, I'm trying to get the client-side X stuff compiled and running on the slug (do not ask why). libutempter is in the dependancy chain, and the emerge is failing with the following:

Folks,

I've successfully set up Gentoo using the various howto's. Since I want to use the slug as music playing device, I have connected a USB soundcard, which is based on the CMedia chipset.

Now, to get this thing working, I've booted into Openslug, ipkg'ed the required kernel modules, copied those modules onto the Gentoo root disk, and booted into Gentoo. The device gets recognized, and /proc/asound is populated nicely with the card0 and all it's friends.

However, running something simple as speaker-test fails with the following error:

I'm trying to plug a DVD and when I do a modprobe of the sr_mod module I obtain the next message:

[bxwen]

I downloaded squawker's tar ball and update to gcc 4.1.1, and now I am doing emerge -e system.

I would like to compile the kernel with the new gcc also. But squawkeer didn't include the src in the tar ball. I was trying to follow the instruction http://gentoo-wiki.com/Gentoo_on_NSLU2#Compiling_a_kernel, but the information is a little outdated. The makefile patch http://www.devroot.de/projects/nslu2/makefile.patch is not accessable. Now I get a kernel, but the intel ixp drivers are not compiled.

question: How can I compile the intel ixp drivers.

Thanks.

Okay. First of all, I wish everyone had nice holidays on christmas and will have a good time on new year's eve also, have fun, drink, shoot rockets.. Don't pass-out outside and don't hurt yourselves, nor anyone else either..

Second thing.. I currently am not able to continue this project unfortunately..
I got other things that I need to focus on now, but..

When I first started this project, I wasn't alone, I received help from many people, mostly people
who started this thread, also some people to thank their efforts are people from nslu2-firmware project.
Without these people, I wouldn't ever have been able to accomplish what I accomplished, so therefore I
must state that these people were the ones who inspired me and made the first sparkle of this project and
during this project, they helped me out to survive through the problems I encountered.

I had some I/O issues as well, don't know, was it because I used over 1GB for my swap partition..
Or was it something else, overheating.. problems with kernel or it's modules, anyway, everytime that
my slug halted during these huge compilations, I wished that it wouldn't had corrupted anything..

Sometimes everything was okay, and I was able to continue emerging (FEATURES="keepwork keeptemp" emerge --resume) but sometimes, shit just happened.. Something got wrong and it messed up the filesystem so bad..
That system wasn't able to read some files at all.. some files just turned to junk.. but most worst thing was..
that when I tried to use these files, system changed harddisk to readonly mode.. Using this harddisk in another
system (pc system) didn't help, problem was there.. Everytime it happened I had to restore a backup..

I had a huge amount of software to compile and when more than 80% was done.. I got finally a cross-compiler
installed succesfully to my server and was able to use distcc.. That helped a bit, but I already had done so much..
Also it didn't quite change it to lightning fast So these backups weren't always quite so fresh if you know what I mean..
I noticed so many times when I restored a backup that before I could start process were my slug hanged again.. I first need to emerge more than 10 packages to be where I were before it happened

So it took time and wasn't that easy..

Now, it's time for me to move on.. And hope that my efforts, along with efforts of everyone else who has helped with this project.. Will have a similar effect it did on me.. and as I did so much for this, I really hope that everything doesn't go to trash bin as it ain't so easy anymore since Jake ain't doing all the dirty work for you I really hope that someone will adopt this project.. Actually I more hope that A GROUP would adopt this project and start a wiki or version-tracker or what ever this group desides to be best way to develop this system, maybe I later join up the team.. Or I just might aswell be so late that all you guys have done this and become a group of system engineers whose knowledge is just so far from mine that I feel embrased to even show myself

Okay, now this has been just about me for sometime.. And wishes that my project wouldn't be forgotten even though that I ain't able to help you anymore for a pretty long time..

Now it's my turn to try to help you with this. There's been a lot of questions about where did gentooslug download-site go?..
Well, it gone to /dev/null.. I was upgrading my system, and I had took backups before I started this project to external harddisk (same that I used with my gentooslug project, I'm poor and don't got more than 1 external discs, and it's only 120gb) So, I downloaded gentoo ISO image, burnt it to a cd.. Formatted my server hard drive.. And noticed that ISO image wasn't able to install, it had a bug

So I did a network install and succeeded, same time, I just happened to got a flu, I live in Finland where it's cold even on summer (atleast I think so, I guess last summer didn't exceed +28 C) and I really don't like cold at all.. Neither does my body, so I propably was in a party and ran around a block naked because of alcohol or something like that, propably not and got this terribly flu, I was doing this system upgrade while the fewer hitted me, it was that kind of fewer that there's a moment when you are okay, and suddenly it raises to about +40c and you feel that you are about to faint.. So I thought that I had it nearly complete when I this happened, just needed to erase some tmp files.. So before I gone to sleep for awhile I entered a command
