Hello everyone, I'm a PF newbie only from this week. I've been using IPFilter all along. On my 6.0 box acting as a router, I was also playing with Mandatory Access Control, especially mac_lomac. This seemed to work with IPFilter but the moment I switched to PF, the machine would panic and reboot. I had mac_lomac_enable="YES" in /boot/loader.conf. This is after I compiled a kernel with " options MAC". in /etc/sysctl.conf I had the following: security.mac.lomac.enabled=1 security.mac.lomac.revocation_enabled=1 security.mac.lomac.ptys_equal=1 And in /etc/rc.conf, all active interfaces were configured with "maclabel lomac/equal" added to the ifconfig args. I'd switch from ipfilter/ipnat to PF by flushing rules in this order: ipf -Fa ipnat -FC pfctl -e pfctl -f /etc/pf.conf At this juncture, the box would panic: panic: mac_lomac_dominate_element: a->mle_type invalid. A memory dump would then occur and the box reboots. I went a step ahead: disabled IPFilter in rc.conf and enabled PF and rebooted. The box would fail to reboot in this case and panic over and over until I disabled mac_lomac_enable="YES" in /boot/loader.conf, the relevant entries in rc.conf and sysctl.conf Anyone using MAC who can reproduce the same? -Wash http://www.netmeister.org/news/learn2quote.html -- +======================================================================+ |\ _,,,---,,_ | Odhiambo Washington <wash@wananchi.com> Zzz /,`.-'`' -. ;-;;,_ | Wananchi Online Ltd. www.wananchi.com |,4- ) )-,_. ,\ ( `'-'| Tel: +254 20 313985-9 +254 20 313922 '---''(_/--' `-'\_) | GSM: +254 722 743223 +254 733 744121 +======================================================================+ If life is a stage, I want some better lighting.
