Hardware :: USB Host Hang On AU1000?
May 14, 2010
I am cross compiling kernel 2.6.33 for an AU1000 platform. All seems ok until large transfers are attempted to or from a USB stick when the whole unit locks up maybe immediately or maybe after a few seconds. Doing an ls etc on the device prior to lockup, all seems well. The problem is USB related I think as the same problem occurs when bluetooth pinging. Attaching an ICE is no use as the ICE will not connect to the unit when hung, the jtag looks as though it is not well at this point.

Many of mails sent from my mail server that are in Queue;The main reason is deffered by domains like yahoo,aol,etc.but there is one more error that i keep getting and that is Host Unknown,Below is an example from mail log,The catch is,test mail sent on the same email id sent from my personal mail from the same server i.e. url was deliveredHowever,another mail containing client information sent from customercare@mycompanysdomain ended up in queue.
There are more examples of the same,around 20 domain have the same problem.

I am working on a cluster for a molecular dynamics class and I have to edit my FORTRAN code (only the newest and best for me!). In order to get through to the cluster I have to ssh in. The network on which the cluster resides is behind a firewall, so I have to ssh through the firewall into the network first.
this is fine, I can login and move files and folders as needed, including sftp-ing into host 1, then into the cluster so I can transfer files from cluster to host and then host to me. This gets rather tiresome, so it would be nice to edit the files in place.
The problem is that when I access my code with emacs it launches the emacs client on Host 1, with no mouse support. I know the purists will howl about how I should be using keyboard shortcuts, but I am a chemist and not a programmer, so the mouse is very nice for me. Is there any way I can perhaps mount the cluster using sshfs so that when I open my code it launches a local instance of emacs? Sorry if this is the wrong forum, but I thought it was network related.

I got a bunch of machines (~10) that I share with my co-workers. I have appropriate .ssh file(s) set up so I don't get prompt for password when I try to ssh.Currently I ssh into these hosts and then do a top to check the load before I start using the machine. Because I don't want to be on a busy host.Can someone show me how to write a script that find a least-busy host given a list of hosts to check? (hardcoded is fine)

I have two servers, one has an empty / and the other has a subdirectory with a large number (4 gig) with many, many files. I need a way to transfer the files en masse from the server with the large number of files to the one that is essentially blank.I don't have space on the used host to simply gzip all the files. I've googled this and see that there may be some combination of tar and/or gzip that will let me do this with some sort of redirection.
I really need and example line of how this can be accomplished. If my explanation seems rather sparse, I can supply more details.

Bit of an odd one, this. I've migrated a website from my old server to a new machine. Both servers run Ubuntu + Apache2. Both only serve a single site, apart from the default site.I've flipped the domain name to the new IP address.The trouble is that after moving the virtual host config over into sites-available, with the necessary link in sites-enabled, Apache attempts to serve from the default web root (/var/www) rather than the actual site content (in /var/www/technology). So for example, an attempt to browse.

I'm trying to get Synergy up and running between my Windows 7 (server) host and my Arch Linux (client) host. In rare exception, synergy works perfect on my windows host, however every time I try and run Synergy on my linux machine I get the following error in messages.log:

I'm running Arch with a barebones Xorg install and SLiM with LXDE. I'm not sure what in the world is causing the problem and haven't been able to find anything of substance in a search.

The internal network is behind nat done by the PC Router.The TP Link is recieving wireless signal from outdoors and it has switching and basic routing capabilities. I'm using the PC router for better routing options.PC Router (or R for short) is a triple-booting machine - Linux, FreeBSD and Windows. It has two lan cards - external (ext_if) - 100Mbps Realtek 8139 and internal (int_if) - 1Gbps integrated Realtek 8169.The problem is that all traffic from R to the network is slow - about 5-20K, while the traffic in the oppoiste direction is all right - about 10MB that is fine for 100Mbps cables, NICs and switches. The problem persist no matter the OS the pc R is running.I've tried some debugging on the situation as follows:
- put another PC at the place of R - everything is fine. That exclude the possibility of damaged cables, RJ-45s, switches and etc.
- connected both of the NICs to the Internet while the internal network is being disconnected and they both work fine (no delays)
- traffic shaping is not running
- there is nothing in firewalls except NATing the internal network (and it is working fine). Actually these firewall rules have been operational for more than months and everything was fine untill a week or two ago.
- changed the internal NIC with another
- connected the internal network directly to the TP and all of the PCs are getting good network performance. Then connected the R machine to the TP as well and there was good performance between the internal network PCs and R.
- R has good performance to the TP. In fact everything has good performance directly to the TP (when not connecting trough R).
- the problem persist only between R and machines from the internal network.

So here's the setup:
Ubuntu 10.04 host inbound port 22 open
FreeBSD 8.0 host no inbound ports open
Both hosts are running sshd currently. What would you do for the Ubuntu host to be able to ssh to the FreeBSD host? A tunnel?

I am a bit of a n00b when it come to linux but I am setting up a test environment were I have a appliance monitoring network traffic. Part of my test requires me to copy a file via RCP from one host to another host. I have two ubuntu boxes. I have allowed the subnet in the etchost.allow for ALL. I have installed rsh-server
When I try to copy the file it looks like it tried to use SCP instad of RCP because it connects to 22 instead of 544. Also note that traffic must be unecrypted thus me trying to use Is there anyway to make ubuntu go old school to allow me to use rcp instead?
Code:
testuser1@ubuntu:~$ rcp /home/testuser1/test.txt testuser1@10.46.41.38:/home/testuser1
ssh: connect to host 10.46.41.38 port 22: Connection refused
lost connection
testuser1@ubuntu:~$ rcp
usage: scp [-12346BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file]

This code is meant to retrieve ascii from a temperature sensor in the fridge, check that it is not the error code (85 degrees) and append it to a csv file. If the reading is 85 degrees, then either my fridge is on fire or the sensor cocked up, in which case it is meant to try again. It's the last bit that I can't get to work.

I've been using F15 through the early releases and now with the final release, and in all of them I've had the same issue:
It will install fine in Parallels, however about 30 seconds to 1 minute after launch, it will hang and completely freeze. This will happen even in run level 3 with no gui running. It doesn't *appear* to happen at the same time every time.
I've tried, disabling networking, sound, and a few other things in the VM to see if that has an effect, but it doesn't seem to make a difference.
I've also tried making a copy of my F14 VM and upgrading. The same issue persists in this case as well.
I have had no issues with F15 on the metal on different machines, as a matter of fact it's been great and required very little hardware work-arounds. Similarly, F14 has run fine and continues to run fine on Parallels on this machine.

I am running fedora 10 on my laptop. I use a usb Western digital "MyBook" 500Gb (ext3). I am using this hard drive since more than 1 year now. Lately I run into a single problem when I read a precise file. The laptop becomes totally unresponsive and I have to manually shutdown the computer. After start-up I can find that the /var/log/message file of my previous session has grown very quickly with "[sdb] Sense Key : No Sense [current]" and "[sdb] Add. Sense: No additional sense information" messages.
I found various similar question on the web, most of the answer were hardware dependent and kernel related. I tried various kernel hoping that my specific problem would be fixed in the next one but with no success (all the kernel since fedora 10 release and two testing one: 2.6.29.5-84.fc10 and 2.6.29.6-93.fc10), I don't have access to a Fedora 11 machine.
I replaced the usb cable and check that the power supply was working correctly.
I am joining part of /var/log/message and the results of lsusb (related to the external hard drive).

I have a GRUB2 USB multiboot setup. Plus I have a multiboot setup on my computer with Ubuntu 9.10, PCLinuxOS, Windows XP, and Fedora 13. The issue I'm having is different but the same. On my USB multiboot, Fedora will hang up on certain devices. Things such as touchpad, bluetooth, etc. On my PC it hangs up on first the bluetooth, then I unplug, then the USB hub, then the mouse and finally the external hard drive. It detects the devices but it freezes on detection. I did get this error before the device detection began:
Quote:
dracut; dracut-005-3.fc13
dracut: FATAL: Don't know how to handle 'root=(0,4)'
dracut: Refusing to continue
dracut: FATAL: Don't know how to handle 'root=(0,4)'
dracut: Refusing to continue
this is on the PC and the problem with the USB is that it will hang up when detecting devices.

I have Fedora 13 installed on a new PC and have two types of intermittent boot hangups. What logs exist within Fedora 13 that may help me identify the cause or causes of these hangups? Todate, a reboot gets over the problems but I wish to get this sorted whilst the PC is still under warranty.

I tried KDE 4.4. I'm back to using KDE 4.3.5. Very bad experience for me, maybe it's just my system openSuSE 11.1 on AMD x86_64 with 4gb memory. Dolphin was unusable. Deleting a file cause it to crash, go in to a directory with a large number (20,000) of images and it would hang and eventually crash. PIM has removed some of the features I used, main one being ability to add Custom Fields to Contacts and assign categories.
In general, the whole thing was slower, not faster, probably because now it requires Neopmunk to be running and the Akondi server. I'll wait a while and try again and see if it gets stable in first update.

I've been running 11.3 for about 3 days, and have been noticing that it seems to crash with depressing regularity. The symptoms are, from the users perspective, the screen just locks up, mouse cursor won't move, won't respond to any keystrokes, and just dead in the water. But, I can go to another system and ssh back into this one. When I do a top I see at least one and sometimes two Xorg processes owned by root that are grabbing every available CPU cycle. This box has dual cores, so it can support two processes running close to 100% CPU. I tried sending the runaway processes a SIGQUIT signal, which did stop them and did restore normal system operation. But I couldn't find the expected core dump anywhere. If I don't do anything to stop the runaway processes, eventually the whole system locks up, including the ssh session.
I haven't been keeping a real close track, buy my general impression is that this only happens when we have two X sessions running. My wife and I usually keep separate login sessions that we switch back and forth from during the day. I realize this isn't a lot to go on. Any suggestions on what I can do to collect some more info. I particular what do I have to do to get a core dump from the runaway process and what should I do with it if I can get it.

Last week I installed suse 11.3. Most of the time it runs fine, but sometimes my laptop just hangs. Mostly I'm just browsing the internet using firefox. For example when I just installed opensuse, and I tried to maximize the terminal window it would hang and not recover. I'm not sure what is causing it. When it hangs I also can't move the mouse pointer, or open the system activity window. I'm not sure I have the minimum specs for kde though, but I can run kde without any problems, it's fast, it reacts fast. At first I thought maybe the amount of ram 512 was not enough so I turned off all the kde effects, but it still seems to crash once in while. I tried checking .xsession-errors to see if I could find something, and I found this

My machine seems to randomly hang, and I am not sure how to work out what is causing it. Are there some logs I can examine that may help me first that I can look at?
My mouse stops, keyboard stops and cpu monitor on screen doesn't move so no idea if its some kind of X thing, os thing, or hardware.

I've had this bug on pretty much all Linux distro's I've tried in the last few months, but because I love Ubuntu and I can't seem to find this bug reproduced anywhere (though I'm not sure it's a bug worth reporting if it's just me) I decided to bring it here: Whenever a program that is not resource intensive (for example, Update Manager while it's downloading packages) is running for around 20 seconds, and I am not typing or moving my mouse, the system will hang. It will sit there for hours on end unless I move the mouse or hit a key.
Worse yet, it will hang on boot and shutdown too. I often have to hit a key to get the hard drive to start reading again and for anything else to happen for that matter. I'm using Ubuntu 9.10 on a relatively new laptop, but like I said before, it's happened on a bunch of distros: Debian, openSUSE, Fedora... I just have no idea what could be causing it at this point.
