The variable ipaddr is a static ip right i.e i need to configure a static ip first then only configure fw_setenv ipaddr right ?

I found this thread after following Alice down the rabbit hole...

I'm having problems getting netconsole to help troubleshoot my GoFlex Home problems.

Back in September of 2013, I installed Arch Linux ARM on it, using the instructions over at the archlinuxarm.org GoFlex Home page. So I'm using v0.6 of the UBIT environment from http://jeff.doozan.com/debian/goflex/v0.6/uInitrd and http://jeff.doozan.com/debian/goflex/v0.6/ubit_start. The GoFlex was successfully serving up a software RAID 5 array on a Sans Digital RAID storage array connected via a SATA-eSATA adapter cable to the GoFlex (yes - the Kirkwood does have a built-in SATA port multiplier!). The storage array was in JBOD mode, and md was properly running a RAID 5 config with four 2T drives - sweet.

Everything was working fine, until I pulled a bone-headed move. I accidentally crashed my Linux laptop, and the only USB flash drive I had on hand was the one in the GoFlex, so I "borrowed" it. I copied the archlinuxarm image using the dd utility on my wife's MacBook. After I rebuilt my laptop, I used dd to re-image the USB flash drive and stuck it back in the GoFlex. Nada. Nothing works... Seems OS X does weird things to ISO images when using dd...

I'm confused as hell about using nc. Does Jeff's uboot image run nc by default, or does it have to be manually setup? I don't have a USB-serial cable converter, so I can't get to the GoFlex console port to configure it.

I did connect the GoFlex directly to my laptop via Ethernet and ran Wireshark. The only packets I can see coming from the GoFlex are a couple of arp requests from 10.10.10.6 asking who has 10.10.10.5. I configured the laptop's eth0.1/.2./3 with 10.10.10.5/.4/.2, respectively, and ran "nc -lup 6666", but get no response at all. I tried "nc -lup 6666 &; nc -l 10.10.10.6 6666", and still nothing.

Any ideas?

You do need to configure it, as Jeff described in the instruction. This set up must be done on the GoFlex Home before you can connect to it with netconsole server on another computer (in this example, 192.168.1.2 is the IP addr of this computer).
fw_setenv serverip 192.168.1.2
fw_setenv ipaddr 192.168.1.100
fw_setenv if_netconsole 'ping $serverip'
fw_setenv start_netconsole 'setenv ncip $serverip; setenv bootdelay 10; setenv stdin nc; setenv stdout nc; setenv stderr nc; version;'
fw_setenv preboot 'run if_netconsole start_netconsole'

But it is not too late! you can download my latest Debian rootfs and put that on new USB thumb. i.e. use second USB thumb drive for this (see the download link in my signature).

After you've booted into Debian, setup netconsole right away for future recovery purpose. And then mount your USB stick, and see if it can be fixed.

Thanks, bohdi.

Here's what I did:

Followed your link and setup a second USB flash drive with Debian. Then I connected the GoFlex Home via ethernet directly to my laptop's ethernet port. I used wireshark on my laptop to monitor the ethernet traffic while the GoFlex Home booted with the Debian USB flash drive in its single USB port. The packet capture showed that the address 10.10.10.6 was arping for 10.10.10.5's mac address.

So I edited my laptop's /etc/network config file to add secondary addresses in addition to the existing eth0 address of 192.168.1.1: 10.10.10.5 on eth0:0, 10.10.10.4 on eth0:1, and 10.10.10.2 on eth0:2.

I then opened three Gnome terminals. In the first, I ran the command as a normal user the command "nc -lup 6666 &" then "nc -u 10.10.10.6 6666" in the foreground. In the second, "nc -l 10.10.10.5 6666", the third, "nc -l 10.10.10.4 6666", and the fourth, "nc -l 10.10.10.2 6666"

I get the following from "nc -u 10.10.10.6 6666":

I get nothing from the others. But at least it's a start. And I can confirm that the kernel is booting, as Wireshark finds that the GoFlex on 10.10.10.6 is sending the following to 10.10.10.4 (although the nc instance listening to the socket at 10.10.10.4 doesn't):

Try this for the second netconsole command:
nc -up 6666 <ipaddr of GFhome> 6666

When you see the count down, press ctrl-j repeatedly.

Once you are at the prompt, get the output of
printenv

And post here! I recalled some user who was in the same situation had to adjust the bootargs so the Debian kernel will recognizes the file system properly(it identified the rootfs type incorectly).

So what's preferable? Change all the references of "ext2" to "ext3", or just convert the filesystem on the flash drive to ext2?

Re: Use netconsole to troubleshoot uBoot without a serial cable
February 12, 2014 06:39AM
So I tried again, and got to the Marvell>> prompt.

In an attempt to make further troubleshooting, I decided to change the netconsole destination, because I wanted to plug the GoFlex back into my wireless router, and access it remotely rather than a direct connection to my laptop. I made the following changes:

Marvell>> setenv serverip 192.168.2.100
Marvell>> setenv if_netconsole 'ping $serverip'
Marvell>> setenv start_netconsole 'setenv ncip $serverip; setenv bootdelay 10; setenv stdin nc; setenv stdout nc; setenv stderr nc; version;'
Marvell>> setenv preboot 'run if_netconsole start_netconsole'
Marvell>> setenv ipaddr 192.168.2.101
Marvell>> saveenv

At that point, I lost the connection to the GoFlex. I waited a couple minutes before powering it down.

On my laptop, I moved the 10.10.10.x address info from eth0 to eth1 (my wireless interface). I connected the GoFlex to a LAN port on the wireless router, setup an nc session on my laptop ("nc -up 6666 192.168.2.101 6666"), and powered up the GoFlex, but got nothing. A Wireshark trace revealed that the GoFlex is still using the 10.10.10.6 source address - but now trying to reach 10.10.10.3 instead of .5 as before. So I tried "nc -up 6666 10.10.10.6", but got nothing on nc.

I monitored the boot process from Wireshark. It appears it's sending the ubit log info to 10.10.10.3 instead of .5 as before. I have 10.10.10.5, .4, .3 and .2 as secondary addresses on my laptop's wireless interface. Wireshark shows that my laptop's 10.10.10.3 interface is replying to .5 that the destination port (6666) is unreachable. What's the actual mechanism for the IP stack to source UDP data coming into various pseudo-interfaces? I'm a network guy, not an OS guy, so I don't know exactly how the IP stack handles data destined for different ip addresses but the same port #.

Anyway, here's the packet capture:

For now, since the u-bit boot handler is getting nowhere after the environment changes I made, I'll try defining only a single 10. address - 10.10.10.3 on my laptop's wireless interface and see if I can get back into the GoFlex and report back here what I find...
Re: Use netconsole to troubleshoot uBoot without a serial cable
February 12, 2014 11:10AM
I can't get any further than doing a printenv at the Marvell>> prompt. According to Wireshark, the GoFlex sends a malformed UDP packet and it looks like nc on my laptop barfs on it and exits. But the GoFlex continues sending data, so I'll parse it out from Wireshark and post it here... Might have to go back to a wired connection - could be xmit collisions on wifi...

nc on my laptop barfed on the first mangled packet. The trace included ICMP packets echoed back to the source saying the destination port was invalid (since nc crashed). I filtered those out to figure what that mangled line should read...

EDIT - I should also mention that I've also changed the fs type on the usb flash drive from ext3 to ext2, and modified its /etc/fstab to reflect that. Are there any init scripts or config files that I might also need to change?

Re: Use netconsole to troubleshoot uBoot without a serial cable
February 12, 2014 02:35PM
Even without seeing the rest of the boot log, I think your problem is with the rootfs type. See this solution:
http://forum.doozan.com/read.php?3,14982,14994#msg-14994

If that still does not get it to boot into Debian, then I need to examine the bootlog again.

And no, there is no need to change any thing in the rootfs. Even fstab change is only a precaution (not really needed if the rootfs file system is ext3 and the kernel expects Ext2, athough not the other way around).

Update: yes, rootfs type is the problem.

No go.

printenv boot_auto
boot_auto=rd_args='rootfstype=auto'; run boot_rdjon@jon-Latitude-E6500 ~ $

Must've got another malformed packet. Re-ran nc and got back in. Then I did:

setenv boot_auto 'setenv rd_args rootfstype=ext2; run boot_rd'

Re: Use netconsole to troubleshoot uBoot without a serial cable
February 12, 2014 04:05PM
Finally got it to boot.

With the GoFlex still powered on, I removed the flash drive and placed it in my laptop just to verify the partition info.Then I plugged it back into the GoFlex.

From the Marvell>> prompt, I issued a "usb tree" command, and found that usb service wasn't started. So I started it by "usb start", and it found my drive. Then I did a "usb tree" again just to verify, then issued "usb storage" and "usb dev" just for kicks. Then issued "boot".

I then saw it found the /boot/uImage and /boot/uInitrd files, and it said it was booting the kernel image. I then used Wireshark to see what it did on the network - it got a dhcp lease from the wireless router (I'm in temporary corporate housing during a move and don't have admin access to the wifi router...)

So now that I'm in via ssh and have a root shell, what info do you need to see so I can save the firmware environment to nand?

Found this problem:

root@debian:~# fw_printenv

This is because you're running an older version of U-Boot. This version probably defines the envs at a different location than 0xC0000. At this point, you have 2 different options:

1. Update U-Boot to the current version by running Jeff's script, see http://projects.doozan.com/uboot. This will allow you to take advantage of newer features.
2. Find out where your U-Boot defines the envs and then modify /etc/fw_env.config. This is a very safe thing to do, since you already running Debian.

With no serial console, updating U-Boot has some small risk. However, Jeff's script is the most reliable way to update your u-Boot, so I would do that. Just remember don't reboot if you see any error during the script execution, post the log here if that happens. And also, your u-Boot envs will be very different, your netconsole will need to be set up again.

After updating u-Boot, setup netconsole right away before rebooting. Again, if anything goes wrong during updating u-Boot, you will need serial console.

I'll report back with the results.
Re: Use netconsole to troubleshoot uBoot without a serial cable
February 14, 2014 08:31AM
This is frustrating as hell. Still having trouble with nc...

Can anyone explain the correct setup (secondary ip addresses on my laptop) to reliably access the console ports while the GFH is booting? Specifically, how do I monitor stdout/stdin/stderr?

It seems that there are differences in nc depending on whether it's the bsd version (default on my Linux Mint 16 laptop) or the Debian traditional (v.1.10-40)

On my laptop, I have eth1 defined as 192.168.2.100/24, eth1:0 10.10.10.5/8, eth1:1 10.10.10.4/8, eth1:2 10.10.10.3/8, and eth1:3 10.10.10.2/8

Up until this morning, I was using the bsd version. I uninstalled it and am trying the traditional (v.1.10-40) version.

With the bsd version of nc, using "What's happening is that when I invoke the old version using "nc -up 6666 10.10.10.6 6666", I can get a session to the GFH (which is 10.10.10.6). U-Boot starts, but errors out because the USB service doesn't start for some reason. I can issue a "usb start" command, then "boot", and it begins loading the kernel, but as far as I can tell, it halts at "Starting kernel ...".

This same version of nc suffers from the "printenv" problem someone alluded to earlier in this thread. As I said in a previous post, Wireshark says the nc barfs when it receives a malformed packet from the GFH. Since it seems it's reproducible, it looks like a bug on the GFH side, since every time I issue a "printenv" command, the output results in a malformed packet every time it gets to the "hd_args_0" variable.

Here's the problem. If I give nc the "-k" option to set the keepalive option on the socket, then I can't specify the GFH's host address - I have to invoke it like this: "nc -klu 6666" - and I get nothing. Wireshark shows that my laptop issues an IMCP "destination unreachable (port unreachable) message back to the GFH. nc on the GFH continues sending the console output, but nc on my laptop doesn't see it.

I tried removing the bsd and installing the traditional version, but all I can get using "nc -lkup 6666 10.10.10.6 6666" is the first couple of lines of the U-Boot log output ("U-Boot 2010.09..."), then nothing. Wireshark shows the same thing - my laptop responds with ICMP destination unreachable messages, which the GFH ignores while it merrily sends each UDP console log packet to my laptop's 10.10.10.3 address...

Any ideas?
Re: Use netconsole to troubleshoot uBoot without a serial cable
February 14, 2014 03:36PM
Although this is only a minor point, the reason that your (U-Boot) netconsole appears to halt at "Starting kernel" is that at that point U-Boot is done, and with it the netconsole functionality.

The next stage is the ksyslog output from the kernel, which will go to a memory buffer. However, the Debian standard initramfs allows the Linux "netconsole" functionality, which will send the ksyslog output somewhere over the network (in full-on rsyslog/syslog-ng compatible formats).

But this has to be enabled, and it is a one-way channel.

To enable it, you need to add an argument to bootargs (so /proc/cmdline from the kernel) of the form:
 netconsole=6666@$ipaddr/eth0,$serverport@$serverip/

.... where the first 6666 is used as the origin port (so irrelevant to all intents and purposes), $ipaddr is the address of the sending/booting device, $serverport is the port on the destination server to send the traffic, and obviously $serverip is the address you want to send to.

I use rsyslog, and so have a file in /etc/rsyslog.d called 10-network-udp.conf that contains:
# enable UDP syslog reception
$ModLoad imudp
$UDPServerRun 514
if $fromhost-ip startswith '10.10.10.' then /var/log/net-udp.log
& ~

This gives me the output from the kernel like this:

Which is great for the warm-n-fuzzies, but frankly the most useful bit is usually the command line!

The critical problem is that this is only the kernel logging, and so the next stage of the boot, the initramfs init script doesn't have it's output relayed. So you don't get to see the messages of the form "Mounting root file system / mount failed due to some incredibly simple error that you could fix in a heartbeat if only you knew what it was". And you don't get to type anything at the "console" where the machine is sitting smugly waiting for you to type "fsck -y /dev/root" or something equally simple.

beausoleil,

Remember that you are running an old version of u-Boot. u-Boot netconsole has been buggy up until the latest u-Boot :) so I would say if you install the new u-Boot by running Jeff's script, then netconsole will be much more reliable. Still, there were reports about intermittent problems with it.

Do you have a second plug? that allows you to use one to monitor the other? this setup never failed on me.

Other than that, I guess the only thing you can do is trying different nc versions on your laptop.

bodhi,

Not sure what you mean by second plug. Second PogoPlug device? No.

And I can't run Jeff's upgrade script because I can't get to the console of the GFH. The best I'm getting now is "kernel booting". But I have no idea if it completes its boot. What ip address does that image of Debian default to if it there's no dhcp server on the network segment it's on?

beausolei,

Setup a static IP in your rootfs. Example (if your router is 192.168.0.1):

#cat /etc/network/interfaces
auto lo eth0
iface lo inet loopback
iface eth0 inet static
        address 192.168.0.100
        netmask 255.255.255.0
        gateway 192.168.0.1


After that if you can ping it, then likely it's booted. See if you can ssh in.

I was just wondering, is it possible to define multiple ip-addresses as the serverip? I've got two machines which I use regularly to access my pogoplug and with the current configuration, only one can access the netconsole.
uBoot problem
March 14, 2014 04:07PM
Hi, i follow the tutorial to revert Pogoplug E02 to factory and then...

Edit /etc/init.d/rcS script, and remove the comment(#) in front of the line reading /etc/init.d/hbmgr.sh start

The device response the PING, but putty say :Network error: conection refused, maybe i do something wrong with te vi command

Thanks for your help

Make sure the Debian rootfs USB is plugged in!

Re: uBoot problem

Ornella,

No problem :)

Just plug in the USB rootfs that you've created above

Using this post: http://forum.doozan.com/read.php?2,12096 

i have DEBIAN runing, reinstaled uBOOT with this commands:

and boot with it.

Rescue system is installed in NAND, for rescue purpose. But it's not a full Debian system in the sense that you want to use it day-to-day. The rootfs that you have created in the USB drive is a full system Debian that allows you to install new packages and use it for any thing you want.
