| To build a kernel for use with the loadable kernel module, follow these |
| steps: |
| 1. do "make bsd" |
| |
| 2. cd to the "BSD" directory and type "make install" |
| |
| 3. run "4bsd/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. cd to the "BSD" directory and type "make install" |
| |
| 3. run "4bsd/kinstall" as root |
| |
| 4. build a new kernel |
| |
| 5. create devices for IP Filter as follows (assuming it was |
| installed into the device table as char dev 20): |
| mknod /dev/ipl c 20 0 |
| mknod /dev/ipnat c 20 1 |
| mknod /dev/ipstate c 20 2 |
| mknod /dev/ipauth c 20 3 |
| |
| 6. install and reboot with the new kernel |
