To build a kernel for use with the loadable kernel module, follow these steps: 1. do "make bsd" 2. do "make install-bsd" (probably has to be done as root) 3(a) NetBSD systems prior to 1.2: run "NetBSD/minstall" as root 3(b) NetBSD 1.2 systems or later: run "NetBSD-1.2/minstall" as root 4. build a new kernel 5. install and reboot with the new kernel 6. use modload(8) to load the packet filter with: modload if_ipl.o 7. do "modstat" to confirm that it has been loaded successfully. There is no need to use mknod to create the device in /dev; - upon loading the module, it will create itself with the correct values, under the name (IPL_NAME) from the Makefile. It will also remove itself from /dev when it is modunload'd. To build a kernel with the IP filter, follow these steps: 1. do "make bsd" 2. do "make install-bsd" (probably has to be done as root) 3(a) NetBSD systems prior to 1.2: run "NetBSD/kinstall" as root 3(b) NetBSD 1.2 systems or later: run "NetBSD-1.2/kinstall" as root 4. build a new kernel 5. create /dev/ipl with "mknod /dev/ipl c 59 0". (for NetBSD-1.2, use "mknod /dev/ipl c 49 0") 6. install and reboot with the new kernel Darren Reed darrenr@cyber.com.au
