I guess I need help. If you've loaded a firewall such as IPFW in /etc/rc.conf a kernel module will be loaded for it, if it's not compiled statically into hte kernel already (which it isn't on GENERIC for either 5.3-RELEASE or 6.1-RELEASE). "kldstat" will list loaded modules (and the IPFW module is ipfw.ko). > Thanks for any help you can give, and I accept any opprobrium for trying > to be a sysadmin, even for my home boxen. > > Chuck Bacon -- [EMAIL PROTECTED] > ABHOR SECRECY -- DEFEND PRIVACY -- Nick Withers email: [EMAIL PROTECTED] Web: http://www.nickwithers.com Mobile: +61 414 397 446 _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
