At first I ignored it, but now I am wondering. Suddently I will spot an extraordinary amount of network traffic and on tcpdump:ing discover my machine is spewing out pfsync broadcasts. On both machines pfsync was NOT enabled, nor had it ever been. pf_enable="YES" and pf_log="YES" was in rc.conf, but nothing about pfsync. I can squish the broadcasts easily enough with 'ifconfig pfsync0 -syncdev down', but I am somewhat concerned over it being mysteriously enabled. One of these machines is a 6.1, the other a 6.0 (though it may have been a 5.x at the time it happened, not sure). pf is being used actively without any 'no-sync' options present; but it is my understanding that no pfsync traffic should be generated until pfsync is explicitly turned on with ifconfig. Does anyone have an explanation for this? I am quite sure I have never enabled pfsync in rc.conf, nor have I ever ran any ifconfig commands that might enable it. I am not running any kind of meta-firewall scripts or anything like that; there should be nothing but the standard FreeBSD rc scripts modifying network interfaces with ifconfig. The second machine I saw this on has only been running for a few days, so I am even more sure I haven't done so on this one than on the other one. -- / Peter Schuller, InfiDyne Technologies HB PGP userID: 0xE9758B7D or 'Peter Schuller ' Key retrieval: Send an E-Mail to getpgpkey@scode.org E-Mail: peter.schuller@infidyne.com Web: http://www.scode.org
