One thing i forgot to mention is in my root there is not configuration file
/etc/sysconfig/kdump or
/etc/kdump.conf, is this anything to do with this and not even /var/crash, i
got the latest kexec-tool

Hi All,
Is there any document on web summarized the hardware (especially,
CPU) that a Linux depends on. For example, if a CPU doesn't support
misaligned access (no exception will be generated when misalignment
access), can Linux run on that?
Thanks.
BR,

Thanks for the suggestion.
tcpdump is good, but it doesn't solve all problems. There are a few reasons:
* TCP packets could arrive out of order
* The data needn't belong to a valid TCP connection
* The app could just discard data (close/flush/etc)
In short,

Hi,
Is it possible for an application (say "snoop", with sufficient
privileges) to monitor data on any socket/file descriptor in the
system?
Here's an example: suppose we have a browser and it creates a tcp
socket to connect to a URL. Whenever the browser issues a read() and
data is pushed to u

Hello All,
I wanted to know what is the best way to generate the kernel crash
dump on kernel panic,
after doing some searching, i came to know we can use kexec to load a new
kernel on the kernel,
i followed the instruction from the following links
http://www.dedoimedo.com/computers/kdump.
Merci mate. :-)
