Things look quiet here. But I've been doing a lot of blogging at dan.langille.org because I prefer WordPress now. Not all my posts there are FreeBSD related. I am in the midst of migrating The FreeBSD Diary over to WordPress (and you can read about that here). Once the migration is completed, I'll move the FreeBSD posts into the new FreeBSD Diary website.

IP Filter won't load - what I did when IP Filter didn't load 19 January 1999

When you are upgrading your system to a newer version of FreeBSD, you need to recompile IP Filter.   This section describes the problem I encountered when upgrading to FreeBSD 3.1-RELEASE from FreeBSD 2.2.8-STABLE and how I fixed it.
The symptoms
I had some problems getting ipfilter to run.  The errors I was getting were during the modload and looked like this:
../../ip_fil.c:215: Undefined symbol  '_fr_checkp referenced from 
                                                       text segment
../../ip_fil.c:236: Undefined symbol  '_fr_checkp referenced from 
                                                       text segment
../../ip_fil.c:237: Undefined symbol  '_fr_checkp referenced from 
                                                       text segment
../../ip_fil.c:239: Undefined symbol  '_fr_checkp referenced from 
                                                       text segment
../../ip_fil.c:1014: Undefined symbol  '_ip_optcopy referenced from 
                                                       text segment

modload: /usr/bin/ld return code 1

The above failure of modload /lkm/if_ipl.o, caused the following errors when ipnat -f /etc/ipfrules was executed:

/dev/ipnat open: device not configured
ioctl(SIOCADDRFR): Bad file descriptor
ioctl(SIOCADDRFR): Bad file descriptor
ioctl(SIOCADDRFR): Bad file descriptor
.
.
.

The file line above repeated, one for each line in /etc/ipfrules.

The solution
If you have upgraded your system, you should also recompile IP Filter before you reboot with the new operating system.  I should have reinstalled IP Filter from scratch

If you really want to see what I did wrong, my silly mistakes are available for your amusement.
