[syslog-ng] netmask

Hallo, I try to use the "netmask" filter option to generate seperate logfiles for different subnets. I tried this filter krzn_all { netmask("10.254.0.0/255.255.0.0"); }; this filter krzn_all { netmask(10.254.0.0/255.255.0.0); }; this filter krzn_all { netmask("10.254.0.0/16"); }; and this filter krzn_all { netmask(10.254.0.0/16); }; No errors have been reported starting syslog-ng but also no messages have been logged. I use syslog-ng 2.0rc1-2 on a debian Etch. Kind Regards W. Thal
