Why?  I like to keep my software up-to-date!

Yes, that is correct and is unchanged from 2.5.1.

Yes

I already have it on, and no, I do not see log entries in archives.log.

No need to run tcpdump since this is only a ossec upgrade.  But, here it is, 
anyway:

# tcpdump -i en0 udp and port 514
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on en0, link-type EN10MB (Ethernet), capture size 65535 bytes
06:39:28.903939 IP 10.XXX.XXX.XXX.57978 > 10.XXX.XXX.XXX.syslog: SYSLOG unknown

Here's the log.  Notice the "dummy" agent -- I created that so that I wouldn't 
get messages about no agents and remoted exiting.  I see that it ignored my -f.

Nope:

# ipfw list
33300 deny log icmp from any to me in icmptypes 8
65535 allow ip from any to any


Thanks for your suggestions; got any others?
