# 7.24. ( SETSOCKOPT ) - I'm getting "ipfwadm: setsockopt failed: Protocol not available" when I try to use IPPORTFW!

If you get the error message "ipfwadm: setsockopt failed: Protocol not available", you AREN'T running your new kernel. Make sure that you moved the new kernel over, re-run LILO, and then reboot again.

Please see the end of Section 6.7 for full details.
