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 AFAIK, syslog has been replaced by rsyslog or syslog-ng on modern desktop linux distros.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. HTH, Jonathan Neuschäfer 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 Vaibhav Jain See if this helps: echo 7 > /proc/sys/kernel/printk Jeff Haran
