Freaky.  My output is the same as yours with the exception of the 1.2.11
string.

recent v1.2.11 options:
<snip same stuff that you have>
ipt_recent v0.3.1: Stephen Frost <sfrost@snowman.net>.
http://snowman.net/projects/ipt_recent/

I'm a little confused about the difference between "recent v1.2.11" and
"ipt_recent v0.3.1"  Is one a kernel component and the other the
userspace part?

I'm also a little confused about p-o-m.  Is this something I can apply
without recompiling my (modular) kernel?  Are there any good docs on how
to use p-o-m?  I didn't see any immediately obvious on the netfilter
site and the p-o-m section seems to end mid-

;)
