Hello

You are not the only one with that problem. For me it turned out it was ther hardware: https://www.newit.co.uk/forum/index.php/topic,3332.0.html

After installing the U-Boot you have to reset, or even unplug, your GuruPlug.

Hi

Could you post the "sheevaplug.cfg" file? I don't know much about it, but maybe there is a hint when seeing the corresponding lines

mfg

Hello

I dont think you have to clone your U-Boot. As long as you have the same U-Boot version on the other Sheevaplug, just copy the environment variables.

In your U-Boot, type "version" to compare the versions.

Hi

Well I wouldn't say it is "bricked", since your U-Boot seems to run just fine. Reinstalling the kernel/root file system might help (http://myownhomeserver.ch/en/reset)

Hi

Must be something which cant be changed then... I dont really know where that could be stored, since it is possible to change quite everything, even uboot...

Maybe like when using an usb-dongle, it would be a possibility to have an encrypted key somewhere.

mfg

Hi

Would be interesting to know why you need the serial number...
Maybe there are other solutions for your problem?

mfg

Hi

First you should do some initial configuration
Then some things to be sure your GuruPlug is secure
Then set up port or IP forwarding on your router so that your GuruPlug is accessible from the Internet
Then you probably need Dynamic DNS
To manage the files either just use the file system and access them using Samba or use another system. Dont have any information so far...

Hi

I just saw today that the GuruPlug Display is available now. Dont know for how long already, but its there

mfg

Hello,

I tried your solution of updating the ftdi driver on my Ubuntu 10.10 because if I want to type something in minicom, it does not work (thus it does not get sent to the GuruPlug it seems like). I cann see the boot messages, but not input is working.

I used your HowTo and I was stuck with

because install-sh was not available.

solved the problem and I was able to continue with make

One question that I have: do I have to execute modprobe every time I restart my Ubuntu or does one modprobe adds the module to the kernel forever?

mfg

Alright, thx.
I never used the GuruPlug to connect to another host, so I dont even have the ~/.ssh directory.

How about the host keys in /etc/ssh? I have several files:
ssh_host_dsa_key
ssh_host_dsa_key.pub
ssh_host_rsa_key
ssh_host_rsa_key.pub

Can I just delete these files or do I have to generate new ones with ssh? (don't remember how to do it right now, but I did that once as far as I remember)

Thanks, but where are the SSH-keys stored? I only know the .ssh-directory within the users home-path, but it is only used/created when I access another computer over ssh FROM the guruplug, and not TO the guruplug. Or do you mean other keys?

The firewall will follow later

mfg

Hello

basically one question: How do I make my GuruPlug secure?

of course: change root password, make WiFi secure, good ssh and user passwords, ... but:

- should I disable the root-user (like it is default on Ubuntu)?
- If some FTP is needed, I guess only SFTP
- Is the GuruPlug (or also the Sheevaplug) secure by default or is anything running that I should take care of?

I know that I have to take care myself of any other applications that I install...

thanks for any answer. I am kind of scared just to allow "public access" (with which I mean that it is accessible though the internet) without knowing if it is secure

Hello

You need a crossover ethernet cable or a crossover adapter. DHCP is not necessary, you can also just set the IP-address manually.
Maybe a crossover cable is not even necessary. Take a look at this wikipedia article http://en.wikipedia.org/wiki/Ethernet_crossover_cable#Automatic_crossover
Just try it out, you will not break anything 

mfg

Hello

I got to the solution that it works: http://plugcomputer.org/plugforum/index.php?topic=1999.0

mfg

I figured out that it should work. The mentioned option CONFIG_LBD is obsolete and as I guess within the Kernel. There is also no concern as long as the Raid is not divided in multiple partitions, since the MSDOS partition table can only handle drives <2TB.

I solved the question here (german):
