Hi,
Can somebody please tell me how to configure
printk() in fedora 15 ? All the articles I have seen on web refer to the
file
/etc/syslog.conf. But there is no such file on my system. I guess this has
changed in the
2.6 kernel.
Thanks

Hi Vaibhav,
Try /etc/rsyslog.conf. However you should be using
/proc/sys/kernel/printk to really configure printk.
Hope this helps,
Ramesh

Hi Ramesh,
As I mentioned /etc/syslog.conf is not there on my system. Could you please
tell me if the name has changed for the file in 2.6 kernel ? Also, does
/proc/sys/kernel/printk provides for the same level of control ?
Thanks

maybe because Fedora now use rsyslog or syslog-ng. In Mint, by default
it uses rsyslog and the configuration file is located at
/etc/rsyslog.conf

Syslog is a user space program, that collects the kernel messages.
So if you don't have /etc/syslog.conf on your system, it likely just
means that you don't have a standard installation of the syslog program,
which can have different reasons. AFAIK, syslog has been replaced by
rsyslog or syslog-ng on modern desktop linux distros.
BTW, Ramesh told you to try /etc/rsyslog.conf (note the 'r'), not
/etc/syslog.conf.

Hi,
Thanks for reply! I found the rsyslog.conf on my system. But
I am finding it hard to configure it. Actually I made some changes but they
are not working.
I made some changes to the kernel and wanted that they appear at either the
console or
some other file. However the changes don't work.
I tried adding the following lines (one at a time)
kern.* /dev/console
kern.* <file in my home directory>
but on making these changes other kernel messages also stop showing up.
Can you please give me some idea as to why this might happen ?
-Thanks

See if this helps:

Thanks but didn't help :(
My configurations in the rsyslog.conf file are still not working.
I added the line
kern.* <filename in my home dir>
but the file remains empty and teh kernel messages are not there even in the
/var/log/messages file.
Thanks

To me it looks like rsyslog is trying to do the right thing but can't
write to the target file. Maybe selinux is preventing it from doing
so?
