Balazs> Balazs> IIRC FreeBSD uses a special file /dev/klog for kernel logging. As you write above, /dev/klog is special file. /dev/klog is using for kernel logging. I knew this. I tried to use file("/dev/klog") of source driver, but as result I saw console error messages "Can't open file.device is busy." Can't "file" of source driver use special file as "/dev/klog" ? To send and receive kernel message of ipfw in syslog-ng, how do I write configuration file of FreeBSD, or how do I configure syslog-ng.conf,or how do I use other tool with combination? I'm sorry my childish English. Thanks you that read my letter. -------------- Hideyuki Nishiyama(Japanese) hideyuki@yk.metocean.co.jp
