1# $FreeBSD$ 2 3To build a kernel for use with the loadable kernel module, follow these 4steps: 5 1. do "make bsd" 6 7 2. cd to the "BSD" directory and type "make install" 8 9 3. run "4bsd/minstall" as root 10 11 4. build a new kernel 12 13 5. install and reboot with the new kernel 14 15 6. use modload(8) to load the packet filter with: 16 modload if_ipl.o 17 18 7. do "modstat" to confirm that it has been loaded successfully. 19 20There is no need to use mknod to create the device in /dev; 21- upon loading the module, it will create itself with the correct values, 22 under the name (IPL_NAME) from the Makefile. It will also remove itself 23 from /dev when it is modunload'd. 24 25To build a kernel with the IP filter, follow these steps: 26 27 1. do "make bsd" 28 29 2. cd to the "BSD" directory and type "make install" 30 31 3. run "4bsd/kinstall" as root 32 33 4. build a new kernel 34 35 5. create devices for IP Filter as follows (assuming it was 36 installed into the device table as char dev 20): 37 mknod /dev/ipl c 20 0 38 mknod /dev/ipnat c 20 1 39 mknod /dev/ipstate c 20 2 40 mknod /dev/ipauth c 20 3 41 42 6. install and reboot with the new kernel 43 44Darren 45darrenr@pobox.com 46
