Thread: [opensuse 10.3] dhcp log to another file

    Default [opensuse 10.3] dhcp log to another file

    My logs are going to /var/log/messages. I touched /var/log/dhcp.log file and chmod 640 /var/log/dhcp.log. And put the following in my /etc/syslog-ng/syslog-ng.conf file (at the end of the file):


    filter f_daemon { facility(daemon); };
    filter f_dhcpd { match(dhcpd); };
    destination dhcpmessages { file(/var/log/dhcp.log); };
    log { source(src); filter(f_daemon); filter(f_dhcpd); destination(dhcpmessages); };

    I have also edited /etc/dhcpd.conf file and added:

    log-facility local7;
    and restarted dhcpd.

    But my logs are still going to /var/log/messages file.

    Noticed in my /etc/sysconfig/syslog file two entries regarding dhcp

    SYSLOGD_ADDITIONAL_SOCKET_DHCP="/var/lib/dhcp/dev/log"
    SYSLOGD_ADDITIONAL_SOCKET_NAMED="/var/lib/named/dev/log"

    Not sure what they are.

    How do I redirect my logs to /var/log/dhcp.log? The dhcp process is running as user dhcpd.

    Thanks.

    Update:

    I have removed log-facility local7; from /etc/dhcpd.conf and restarted dhcpd.

    Edited /etc/syslog-ng/syslog-ng.conf file and added:

    filter f_dhcpd { facility(daemon) and match('dhcpd:'); };
    destination dhcpmessages { file(/var/log/dhcpd.log); };
    log { source(src); filter(f_dhcpd); destination(dhcpmessages);};
    and restarted syslog-ng. Now I am getting dhcp logs both in /var/log/messages and /var/log/dhcpd.log file.

    How do I stop it going to the /var/log/messages file?

    You have the edit the filter f_messages to exclude DHCP messages.
