General :: System Crash Doesn't Save Info To Kern.log
Jul 23, 2010
I am currently creating a usb device driver consisting of mostly read and write commands. It can successfully read/write using the bulk endpoints, however reading from the interrupt endpoint causes a system crash.As the crash happens whilst writing to kern.log, the file doesn't get a chance to close, therefore done of my debug printk calls are saved. Also, I get know response from using the magic sysrq key.
Does anyone have an ideas on how I can get any system information about what's causing the crash, or possible causes of the crash. (Using a usb sniffer running on another pc, I can see that the packet is coming in from the interrupt endpoint).

I have a gentoo distribution and need to store the information of dmesg collected until a system crash. At present, after a reboot or a crash the information in dmesg are lost and are not available at the next reboot. How can I save all the information in dmesg until a crash and read them after the succeed reboot?I also checked for dmesg.x files in /var/log or similar files but with no success.

I'm working on a Soekris net4801 that is running an unknown distro of Linux. The kernel is 2.4.29, and iptables is v1.3.4.
I can't work out how to save the iptables. I searched the whole system for files/folders containing the name "iptables" and got 3 results:
/user/local/lib/iptables
/sbin/iptables
/lib/iptables
I've tried iptables save, iptables-save and iptables save active.
"iptables save" and "iptables save active" give me an invalid argument error. "iptables-save" isn't a valid command. "iptables --help" gives me a list of valid switches, none of which have to do with saving.
how I can save the iptables?

I'm trying to run a shell script on a kern board (av1100) that shows some text output on the attached screen. The big problem is that the screen goes to blank in like 2 minutes.I'd just like to have the script showing it's output while the thing is on.Isn't there a command to stop the screen from going to blank?p.s. there is no bash available, just #!/bin/sh
Code:
#!/bin/sh

my mediacenter is attached to an beamer with the optimal resolution of 1280*720 ubuntu 10.04 doesnt offer me this revolution (on my intel 915 graphis controller). this means i have to add this resolution to the possible resolutions. first i used cvt
Code:
cvt 1280 720 60
and got this result:
Quote:
# 1280x720 59.86 Hz (CVT 0.92M9) hsync: 44.77 kHz; pclk: 74.50 MHz
Modeline "1280x720_60.00" 74.50 1280 1344 1472 1664 720 723 728 748 -hsync +vsync
then i added this to xrandr
Code:
xrandr --verbose --newmode "1280x720" 74.50 1280 1344 1472 1664 720 723 728 748 -hsync +vsync
and
Code:
xrandr --verbose --addmode VGA1 1280x720
now i can select and use the new resolution - until next reboot. after an reboot 1280x720 is again not available. even if i work with sudo - the resolution isnt there....

I remember screenshots in which a cli window is opened and in it kernel version, processor type, and other information is displayed along witnice little ascii art of the distribution logo. I have seen it for gentoo and debian, but forget the name.

I'm trying to come up with a startup init script that will check to see if the system was shut down gracefully, or if it is rebooting from a poweroff or something similar?Anyone know of a way to check for this condition with the least amount of room for false positives or vice versa?My intial thought is just a startup script that will will check for a file on startup, and on a proper reboot/shutdown just touch the file. But id like to avoid that type of script if possible,

I've recently lost my window options, had to somehow manipulate my way to Xchat and ask some people how do I get it back (it was metacity --replace, and after I decided to stop the command and run it in background the X was completely useless so I had to do killall -u user). And that was after the internet connection stopped working for some reason (might've been the ISP).
The thing is, after using linux a long time, I still get the feeling that on dire situations, I don't know the good tricks (stuff like metacity --replace). I feel like a really need like a "rescue" cheatsheet for things like: how to save the X no matter what without pressing reset how to reset the system to "normal state" how to connect to the internet through the command line how to monitor what the X is doing (using ubuntu linux 10.04 btw)

we have a Win NT4 system used for an important application used at two places. At one place it has gone bad. I want to create an image from good system and restore it at the second location. Is it possible to do this using "clonwzilla live cd"? Does it harm the good system? Can I save the created image to an USB drive?

I walked into work this morning and had a message from the system that my root drive had very little space. I traced it down to my message.1 file and kern.log.1 file. Together, they were over 2 GB.I am able to browse the file shares.

I find it very frustrating that documentation suggests using PEERDNS=no in /etc/sysconfig/network-scripts/ ifcfg-eth0 in order to override resolv.conf information only to find out that both NM and network init scripts ignore DNS1, DNS2 and DOMAIN settings.So my question is how do I correctly configure resolv.conf settings that will persistently override dhcp information on a F12 system that has NM removed and uses the network service scripts?

I have two 10.04.1LTS command line servers running different overall jobs. One is an upgrade that started as 9.10 and was upgraded to 10.04LTS when it came out. It has since been upgraded to a 10.04.1LTS server. It's ssh login displays the following:
Code:
bob@b-desktp:~$ ssh admin@192.168.0.153
admin@192.168.0.153's password:
Linux server.nnbob.net 2.6.32-27-generic #49-Ubuntu SMP Wed Dec 1 23:52:12 UTC 2010 i686 GNU/Linux
Ubuntu 10.04.1 LTS
code....
No mail.Last login: Mon Dec 27 17:00:10 2010 from b-desktp.nnbob.net.Notice the nice system information presented there. How do I get the other (upgraded) server to do that too?

I switched to lxde, love the speed, but it has one major glitch: it doesn't save the settings. the most annoying: the setting " enable tapping" of the touchpad isn't saved afer a reboot. I tried the following:
delete ~/config/lxde ~config/lxpanel ~/config/pcmanfmand the other solution i found in the forum:Opensuse 11.3 LXDE Keeps Changing My Wallpaper Back To Default
I'm using opensuse 11.3, added repo lxde, updated everythng. So far, nothing.

I have recently installed Ubuntu 10.04 and from my id which has administrator rights, I am unable to save any files as well as unable to change the location in firefox. The firefox version is also in the snapshot as well as the options window. Is it that my profile has been corrupted or is there some bug in firefox.

less doesn't save command history, i.e. file .lesshst isn't created. If I create it manually, nothing writes to it too.OS AIX 5.3 I think linux users can have the same issue, hardly this issue depends on OS.

I am running Wheezy 7.9 and recently created a file, in xorg.conf.d, to set the monitor configuration because the EDID is not always read from the monitor. Everything works great but when the EDID is not read the monitor name, as shown in System Settings>Displays, shows as Unknown. I have the vendor info and modelname in the config file but they do not show in the Display GUI. Is there some variable that I can set in order to get a good monitor name displayed?
Probably should include some more information. I am using the Gnome Classic desktop and gdm manager. Here is the monitor conf file that I put in /etc/X11/xorg,conf.d
Code: Select allSection "Monitor"
Identifier "Monitor0"
VendorName "VSC"
ModelName "VA912b"
DisplaySize 376 301
HorizSync 30.0 - 82.0
VertRefresh 50.0 - 85.0

I've been trying to figure this out... What command does the system use to display this at login:
Quote:
System information as of Fri Oct 1 08:35:54 CDT 2010
System load: 0.28
Usage of /: 10.8% of 17.89GB
Memory usage: 51%
Swap usage: 3%
Processes: 112
Users logged in: 1
IP address for eth0: <ip.address>
It's not uname, free, top, df, uptime, etc... Also doesn't appear to be anything in /proc that I've found. Anyone know what it is? I want to grab its output as part of a script. I could use other commands I suppose, but this system info output is neat and concise.

I am a new user of Linux and it was just my luck that my Windows partition along with my WD 350GB external HDD got infected with a virus. My computer science buddies suspect that the virus in my HDD was in a folder called System Volume Information. Right now, my Windows partition's been removed so my netbook is 100% Linux. I also deleted said folder from my HDD. However, the System Volume Information folder in my HDD still keeps on appearing.
I read that the System Volume Information folder is a Windows folder so I'm wondering why it still keeps on appearing? Is this still the virus? I'm skeptical but right now, I really don't know.

I'm a linux newbie and scripting novice and I'm trying to pull auditing info and dump it into a file. I made some login changes so it would get audited but I don't want to have to sift through the log to see who the user was and what was done. This is what I have below here and I can't seem to get it to extract the info want using the event id. The "ausearch -a $10" from the script should get it from the 10th column but it's not working.If I can get this to work I would like to add additional aureport options.
