Debian :: Kernel Keeps Reporting A Printk Bug In Syslog Recent Printk Recursion
Mar 5, 2010I've got a VPS node running 2.6.26-2-openvz-amd64 and several guest machines. My kernel keeps reporting a printk bug in syslog:
[Code].....
This is somehow being replicated on the guests machines. I've read that printk is a kernel function that prints out a message, during bootup Has anyone experienced similar problem or have a more experience with this? Does it have negative impact to the host performance?

Apr 7, 2010Kernel driver function was called via ioctl and returned success, but when I checked the kernel display buffer with dmesg the printk message was not there. Then when you do lsmod, the driver you were calling showed "used by zero". So it seems like the kernel driver was not accessed. In the kernel driver, I had many printk statements, but nothing printed in the buffer. if the driver get accessed and what could cause this?

Red Hat :: Disabling Kernel Messages On Console?
May 17, 2010is there any way to disable kernel messages on the console? The problem I have is that it is almost impossible to work on the console due to a flood of file system errors from the kernel.
I've checked /etc/syslog.conf and disabled kernel logging to the console. Even with syslog turned off the messages still flood the console.

General :: Direct Kernel Messages To COM Port?
Mar 31, 2010I need to debug a kernel panic. It prints some long log to the console, but even if i set 1920x1440 VESA framebuffer mode, i can't see it whole.
So, i would like to direct all the kernel messages to a COM port and read them on another machine. Is there any way of doing so? What are the other (maybe better/easier/etc.) ways of catching whole kernel panic messages or scrolling the ones already displayed?
Fedora :: Saving Kernel Shutdown Messages As Text?
Jan 30, 2010When my computer shuts down, I always get a long error message from the kernel. It's the very last thing the computer does and I can't even use the keyboard, since the system is halted. I wanted to read it more carefully (it's very long and doesn't fit the screen) and file a bug report against the kernel with it. But for that, I needed to save all that text in a file.
View 1 Replies View RelatedGeneral :: Pipe Kernel Messages To Another Process As They Occur
Apr 13, 2011I have an OLED screen on my laptop that I have configured to show status information. The current driver I have installed in Linux for it is able to display messages by sending them to a script as an argument separated by spaces.Example: the command /opt/asusg50oled/utils/notify.sh Hi Everybody "Hello World" displays on the oled screen:
Hi
Everybody
Hello World
If another message is sent before the old ones disappear and it reverts to status info, it pushes off the top message. Example: less than 30 seconds after the previous example, /opt/asusg50oled/utils/notify.sh "Bananas have potassium" is executed:
Everybody
Hello World
Bananas have potassium
What I want to do is have kernel messages (the kind you see by running dmesg) forwarded to this script. For example, when I insert a USB drive, the following information would show on the OLED screen as they're logged:........
Ubuntu Installation :: Kernel Messages And Display Becomes Corrupted
Feb 1, 2011Recently I am trying to install the latest Ubuntu / Xubuntu but after the kernel messages the display becomes corrupted. The machine is a Clevo laptop with the dreaded SIS 671 / 672 chipset. The Ubuntu 8.04 is working flawlessly. Any other version I get several problems and depending on the mood of the system I get a vertical running display ( not readable ) or a left horizontal displaced screen (readable) ...
I tried more tan several CDs ranging from 9.01 to 10.10 both Ubuntu or Xubuntu. What is the plainest (simpler ) VGA mode in order to install it? I have tried vga=normal and even VGA =3 with no success. With the latest Ubuntu 10.10 I get another problem it simply does not recognize the HDD / SSD. I have traced the SSD problem with the sata_sis module in kernel 2.6.35 and up... Other distros have the same problem ...

Fedora :: Kernel: Imklog Continuously Generating Error Messages
Oct 4, 2010I am using latest updated Fedora 13 (presently kernel-2.6.34.7-56.fc13.i686).
kernel imklog error messages fills my hard disk again and again, /var/log/messages file becomes more than 5Gb daily.
the /var/log/messages file contains following entries:

OpenSUSE Install :: Autologin - Syslog - Kernel Messages - Console
May 9, 2010What i'm trying to accomplish seems rather silly but is needed for my little project here.
I'm using OpenSuSE 11.2 as a media center PC and need it to login automatically(console not X). That one i accomplished without problems.
However, after login i can see all the info about the services that were started and that needs to "go away".
One could do a "clear" in the .bash_rc and or .bash_profile but it will still show the login prompt which i don't want to see either (i don't even want to see the blinking cursor as well).
Question: How do i accomplish that so that the login console shows only the "splash screen" without any output of the kernel,rc.status nor the "issue-file"... just a plain blank screen ?
Ubuntu Servers :: Redirect Messages From Kernel Ringbuffer To A Logfile?
Aug 2, 2010Is there a way I can redirect messages from kernel ringbuffer to a logfile, e.g. with rsyslogd? With redirect I mean that the messages do no longer appear in dmesg, but only in the logfile.
In my case that should be iptables log messages.

Server :: Sendmail Relay Messages To Ext. SMTP Server?
Jan 31, 2010I've got a server set up with Debian. The problem is that my ISP doesn't allow usage of port 25 (as I understand a lot of ISP's don't).I have PHP scripts hat use the mail() function to send e-mails through the Sendmail application.So, my question is: How can I relay messages sent to sendmail to an external SMTP server (like Google Mail, for example)? Would this be easier to do in the PHP configuration, or on the Sendmail side of things?I've used PEAR extensions in PHP to achieve this before, but scripts downloaded from the Internet generally just use the basic mail() function, and it would be a real pain to modify them all.

View 1 Replies View RelatedFedora :: Kmail Keeps Downloading ALL Messages From The Server?
Mar 24, 2011Since yesterday Kmail has started downloading ALL ,messages, not just the new ones, from the server. It is a real pain as the mail check takes about twenty minutes and Kmail usually freezes afterwards. Then I have to close it down and after restart it downloads several thousand messages all over again. This has only started happening since yesterdays Fedora update, which I think was anything to do with Kmail?
I am using Fedora 14.
EDIT: I have just notice it is not downloading ALL messages, just the read ones. The new messages are being left on the server but the old ones are downloaded and flagged as new. So it seems as if something has got flipped around somewhere?

Server :: BIND Messages Filling Up SysLog?
Dec 9, 2009I have the following BIND messages filling up my SysLog that I'm hoping someone can explain to me:
Code:

[code].....
I would expect this behavior if "domain.com and anotherdomain.com" wasn't a domain that I hosted. But this is a valid domain that this server should be answering for. In my named.conf I do have the
Quote:
allow-query { any; };
option on every zone. This is my slave server and I have the primary shut off so I can test this slave server. FYI: So far queriers still seem to be working. The pages for the sites are still coming up via the internet.
