To build a kernel for use with the loadable kernel module, follow these
steps:
1997-05-25 15:45:04 +00:00
1. In /sys/i386/conf, create a new kernel config file (to be used
with IPFILTER), i.e. FIREWALL and run config, i.e. "config FIREWALL"
1997-05-25 15:45:04 +00:00
2. build the object files, telling it the name of the kernel to be
used. "freebsd22" MUST be the target, so the command would be
something like this: "make freebsd22 IPFILKERN=FIREWALL"
3. do "make install-bsd"
(probably has to be done as root)
1997-05-25 15:45:04 +00:00
4. run "FreeBSD-2.2/minstall" as root
1997-05-25 15:45:04 +00:00
5. build a new kernel
1997-05-25 15:45:04 +00:00
6. install and reboot with the new kernel
1997-05-25 15:45:04 +00:00
7. use modload(8) to load the packet filter with:
modload if_ipl.o
1997-05-25 15:45:04 +00:00
8. 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:
*** KERNEL INSTALL CURRENTLY UNSUPPORTED ***
1. do "make freebsd22"
2. do "make install-bsd"
(probably has to be done as root)
3. run "FreeBSD-2.2/kinstall" as root
4. build a new kernel
5a) For FreeBSD 2.2 (or later)
create devices for IP Filter as follows:
mknod /dev/ipl c 79 0
mknod /dev/ipnat c 79 1
mknod /dev/ipstate c 79 2
5b) For versions prior to FreeBSD 2.2:
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
6. install and reboot with the new kernel
