Hi, The book rubini says -- "if u dont want to clobber the system logs with monitoring messages from your driver, then run klogd with the -f option or change /etc/syslog.conf to suit your needs" but "man klogd" says running klogd -f diverts the lof messages to that file, what it mean, as far as i understand is that all system logs wld be diverted to this file, instead of going to syslogd, so how does it matter, you still are clobbering the system logs with monitor messages from your driver ?? !!. Are not the two statements conflicting ? Is there a way to divert just you own driver's log messages to a paritcular file using printk and klogd/syslogd, such that this file wont have any system messages. ? thanks Amit -- Kernelnewbies: Help each other learn about the Linux kernel.
