I just took a look at the code:
if (q != NULL) { /* should never occur */
if (last_log != time_second) {
last_log = time_second;
printf("ipfw: install_state: entry already present, done\n");
}
return 0;
}
What if I just hack the "printf ..." line out of there? Would that 'solve'
it? I know it's dirty; but would things still work?
Thanks,
