Three months ago I replaced the 4GB microSD that came with my Gurplug Server Plus.  I installed the root fs on it and it
ran over a year until I kept getting I/O errors and it became unbootable.

I bought a Kingston 4GB card three months ago to replace the original and had a hard time recovering many of my files
from the original.  The new one is ext2 and I used instructions on the web to install Squeeze.

Now I can't ssh into the plug and when I use the JTAG I get weird errors about the shell interpreter.  I tried restarting the
ssh service and got a "file not found" error when I can see the file.  I removed the microSD and using a USB adapter I
try to fsck it and get


I can see partitions.


Is this microSD trash or is there hope of repairing it?  Anyone else having problems?

I have an older generation plug and have heavily modified it to deal with heat.
Removed internal power supply and now have external one.  Heatsinks on chips and
external fan that blows air over heatsinks.

When I ran usb tree, my SD showed up as number 3 and that was what I was mistakenly using.

This is what I should have done:



Device 1 is the SD card and device 2 is a usb stick

So I changed the device number to 1 and now the guruplug boots up.

bootcmd_usb=usb start; ext2load usb 1:1 0x00800000 /uImage; ext2load usb 1:1 0x01100000 /uInitrd

I looked at other posts describing problems with the DENX uboot and microSD but I see something different
when I try installing on my Guruplug Server Plus.  I had a previous version of uboot load from a microSD but
had to replace due to I/O errors corrupting it.

I followed these instructions to install Debian Squeeze on a new microSD

http://www.cyrius.com/debian/kirkwood/sheevaplug/install.html

Everything went well until I tried booting from the new SD.  I tried both a USB boot and the SD instructions.



I tried both usb and SD (it was unclear from the instructions whether Guruplug always sees SD as USB or just during install).

I don't understand why mmc init isn't in uboot help menu and I get "command not recognized."

I accidentally deleted some mp3 files.  I searched for an undelete utility on the web and came across this
http://www.cgsecurity.org/wiki/TestDisk_Download

There is a binary version for
Marvell 88F628x Linux 2.6.32 Synology DS111, DS211, DS212+ NAS
When I untarred and tried to use it on my Guruplug Server plus, I get a permission denied error even though I
chmod a+x the binaries.  It is installed on a vfat formatted external usb.  I have a 2.6.33.7 kernel but the error
suggests this is not the conflict.

Any ideas?

I don't have an IP camera and I don't know if these solutions will work with one.

I have a Guruplug server plus with the default Debian Lenny and a usb camera. I use this package
http://code.google.com/p/mjpg-streamer-mini2440/downloads/detail?name=mjpg-streamer-mini2440-bin-libjpeg62.tar.gz&can=4&q= to provide live video.  The mjpg streamer package from other sources are built against a different version of libjpeg from what is on the Guruplug.  If you have a usb camera you could use a shell script to grab images with this package.

I have a Guruplug Server plus with the filesystem on  a 4GB microSD and have 64GB USB stick
mounted as vfat.

I set up the default Plogger photoalbum and everything seemed fine- I could upload pictures and
create albums.  I tried to move the folders for photos to the USB stick and leave symlinks to them
in the /var/www tree.  Now Plogger shows a mostly blank screen for the main page. Admin login shows
the filenames but the thumbnails are broken and  albums are blank. I moved the jpgs back to
/var/www but the page is still blank.

I tried a new install (RC1.0) from the Plogger website but get a php error


It looks like there is no longer development of the Plogger project so I am giving up on it.

I found another app that looks equivalent:
http://piwigo.org/

Before I set up the mysql account and configure it, is there a way to have all of the large files for the picture
on the USB stick?  Since it is vfat, I know there are some permission issues.  I have it mounted like so:

I have a very stable (but slow) wireless client plug using the binaries distributed here http://www.plugcomputer.org/plugwiki/index.php/Setting_GuruPlug_to_be_a_stable_WiFi_Client

I came across this posting https://gist.github.com/961478.

Does it look like this patch could address the problems described here?
http://www.plugcomputer.org/plugforum/index.php?topic=4397.0

I would like to try a recent kernel on the plug to see if the slow data transfer improves.

I have a similar problem.  If my plug loses power, it will hang at the Marvell prompt and I need to connect with serial terminal and issue a command to boot it.

It hangs with this error:

I upgraded u-boot and have it boot from an SD card using the instructions from popon here

http://plugcomputer.org/plugforum/index.php?topic=1642.15


I would like to try adding the mmcinit commands but I can't figure out how to pass them to u-boot

Here is my configuration:


According to this tutorial http://www.cyrius.com/debian/kirkwood/sheevaplug/unpack.html, should I have a bootcmd_mmc
paramter?


Could someone write out the steps to amend the mmcinit command to u-boot? 

Based on the original instructions that worked for me I would do this:

I changed the mount options suggested (actually I tried it with sync and got 4.9MB/sec)

When I changed the suggestion to async I get

# umount /dev/sdc1

# mount -o rw,noexec,nodev,async,noatime,nodiratime /dev/sdc1 /media/usb1

# time dd if=/dev/zero of=/media/usb1/test bs=1M count=40

40+0 records out

real    0m0.449s
user    0m0.000s
sys     0m0.320s

That's more like it! 

Now to get udev to not mount the drive with the default settings.

If I understand correctly, external drives don't spin up fast enough for fstab to mount
them so they get mounted with the udev rules for external drives.

I tried using a USB 1TB external drive and the performance is poor.  It is mounted
async on a guruplug.

Any ideas why it is only 6.5 MB/sec?  Why is this much lower than 25 MB/sec?

I came across this and found some useful tips

http://www.cyberciti.biz/tips/linux-security.html

I am running a webserver on the plug, but I can only connect to it from
outside via ssh.


Some questions I have are why limit network connections to 1024 kb/sec
for lightppd?  That seems very low?
 
http://www.cyberciti.biz/tips/lighttpd-set-throughput-connections-per-ip.html


I implemented these since suggestions ssh is the only connection to the outside world.

Hi,

I have a guruplug server plus and tried to use a 1TB USB drive that is NTFS formatted.
Disk read write was abysmal from a Vista laptop 100 kb/sec: likely a combination of wireless
connection, SAMBA and ntfs-3g driver.

There is a lot of data on this NTFS drive so I can't reformat.  I looked at buying an eSATA drive
since this is supposed to give better I/O than USB2.0.  I would format a new drive as ext3 and
keep it on the Plug.

Can anyone recommend an eSATA drive model?  Reviews are mixed for all of the devices I looked at.

Another option I came across is Cloud Appliances.  These have an embedded system allowing
connection from LAN or WAN.

If I plug this into my router I via ethernet cable, I could simplify the setup of NAS compared to configuring Guruplug.
However, I don't know how customizable the settings are.  There seemed to be some restriction on connections.

Advice anyone?

Hi,

Perhaps this thread will be useful.

http://www.plugcomputer.org/plugforum/index.php?topic=5753.0

I did *read* all of the posts.

Yours clearly states that you want to go back and forth from AP and client mode and you are using an Ionics Stratus Zigby
rather than a Guruplug. 

I only want client mode on a guruplug.  I'm not a software engineer either. 

I did try the command to reset uap8xxx but it gave a file not found error.  Now I see that this has to happen in the startup scripts before the module is unloaded.  I was working from commandline.

I am trying to be methodical and reproduce the steps others took to fix the problem.  Now my startup scripts are a jumbled mess from all of the wifi client fixes I tried to implement.

Could someone update the wifi client fix wiki page?  The default patchfiles (provided from an older kernel version build) aren't compatible with a clean 2.6.33.7 kernel (I got missing macro definition errors) and none of this reseting stuff is in there.  It may save someone else from wasting a lot of time.

I want to only use my plug as a wireless client so I followed the instructions http://www.openplug.org/plugwiki/index.php/Setting_GuruPlug_to_be_a_stable_WiFi_Client to flash the fixed 2.6.33.7 kernel and install the 2.6.33.7 modules and the
wireless files.

I am unable to get the wireless client module to work. 

When I try to do this

 
Instead I get this

Any ideas?  Why is there no tainted kernel warning?
