if you use dhcp on the plug (and don't want to do any netboot stuff) you don't need to put the ip line into bootargs. If you remove this, the plug should still come up, request dhcp and configure it's interface.

From your netstat and ifconfig also ssh should be reachable. How do you try to connect to ssh? Are plug and PC on the same subnet? Any firewalls on the plug (iptables -L)?

for the depmod stuff...

You load a kernel directly from flash memory and your rootfilesystem is also in flash. Updating a kernel involves two parts, the kernel and the kernel-modules. Your modules are under /lib/modules/kernel-version on the rootfilesystem. Your kernel is in flash. Update scripts assume that they can simply place the kernel in /boot/ or something like this.

So you still load the kernel from flash (if i'm right this is the original kernel delivered with the plug) but updated the modules in the rootfilesystem. They don't match. You need to flash the kernel. Check forum and wiki, i'm sure it is described somewhere

it should be the newer version.

The sheevaplug produces less heat then the guruplug. As the heatspreader is on the topside of the case, you could drill some wholes into the case to aid heat dissipation. A Fan should not be necessary.

current plugs have "improved" psu. Whatever this means. You can wait if they also fry.

If you want to take precautions, you can open the case (screws under the rubber feet), take out the psu (its a box, easy to take out, cut the wires). drill a whole in the case, put through the wire of the external PSU and solder it to the cut of cables.

1) the network seems to be misconfigured, please check the content of /etc/network/interfaces, your mac addresses and your dhcp server (if in use)
2) the ssh is running, but the system has a misconfigured network
3) Your kernel is loaded from flash and i would say it is the original kernel. But in your root-filesystem there is probably a different kernel (and its modules). if the old modules still exist, you can run depmod -a to recreate the dependency file. Or you need to flash the kernel. I think there are some scripts for this, please search/google how to do it.

be careful with dist-upgrade, ubuntu 9.04 is the last version that supports armv5 (in case you rebuild the system i suggest switching to debian).

it would be interesting what errors you see when you reboot the plug with attached console.

But having connected a serial console and replacing init was a good idea. As a result you are now running a single process (bash) which did not do any init tasks. So nobody mounted procfs on /proc and ifconfig can't find anything there. So this seems fine. Please check a normal boot process with the console attached.

just compile a kernel. After all it's an embedded system and you can and should customize it to your needs.
22  Linux Stuff / Kernel / Re: NFS booting hangs on firmware load on: June 30, 2010, 12:25:28 AM
It looks like the plug is attached with a cable, and the driver for the ethernet interface is in the kernel, isn't it? So NFS boot should be possible and in the output posted the mount succeeded. Wireles then fails, but this could be moved to a seperate startscript.

vesa mount defines the pattern and screw sizes on the back of a screen. If a plug should be mounted on the back of a screen, it basicly needs a least one gauge (or two in the right distance) where a screw (m4-m6, depending on vesa standard) can pass through.

But as most screens have a mount attached (the foot on which it stands) i think that two threadholes in the case of the plug would be the simplest solution. You could then attach a plate to the plug if needed and bolt it into anything you want.

java programs are (most of the time) architecture neutral and can run anywhere, where java is. But java itself (the virtual machine) must be executed on a processor, so it is not architecture neutral.
25  General Category / General Discussion / Re: Unable to install JRE 6 on: June 28, 2010, 04:19:13 AM
The java installer is a shell script with an embedded binary archive. You can read it and execute the steps manual.

You did download a java version for armv5, right?
26  Linux Stuff / Kernel / Re: Cannot tftp-boot custom kernel, but only factory default kernel on: June 27, 2010, 12:44:04 PM
Here is a minimal config for U-Boot 2010.03-01161-gd91b0a9. It will load kernel and ramdisk from the server 192.168.1.10

Code:
baudrate=115200
ethaddr=aa:bb:cc:dd:ee:ff
ethact=egiga0
ipaddr=192.168.1.100
serverip=192.168.1.10
netmask=255.255.255.0
loadaddr=0xb00000
tb=tftp 0x800000 uImage; tftp 0xb00000 uInitrd; bootm 0x800000 0xb00000
bootargs="console=ttyS0,115200 ramdisk_size=8096 root=/dev/ram"
stdin=serial
stdout=serial
stderr=serial
bootcmd=run tb

enter u-boot modify bootargs to include init=/bin/bash boot, change password.
28  Linux Stuff / General Linux questions / Re: NFS server and mapping of user ids on: June 25, 2010, 03:04:14 PM
if your laptop understands it, you can use nfsv4. It does userid-mapping by name and is a lot less hassle. Just create a user with the same _name_ on the plug (id does not matter). nfsv4 will do the mapping.

Or keep your user-ids manually in sync. If it is only you and your laptop that should not be too hard.
29  Hardware and U-Boot firmware / Hardware / Re: Ionics Nimbus 100 - Ubuntu? on: June 24, 2010, 12:51:35 AM
i would stick with debian. Ubuntu 9.04 is the last version of ubuntu supporting the armv5. So no upgrades and support/security updates will run out in October 2010.

You can look for a python2.6 backport for debian lenny, or upgrade to squeeze/testing which has a python2.6 package.

the kernel config of sheeva with linux is available (as are the patches and the cross compiler). It is not that hard.
