On a somewhat related note, although a tad off-topic...

I'm curious as to how some of you using IDS are capturing sessions that
don't make it past the first line of defense packet filtering.

I have an IDS on a spanned port of a packet filter, who only allows
established traffic in.  Obviously I'd never see these RPC related
exploits due to the fact I'll only log and capture the first SYN.  Often
thought about the use of netcat or something, but staying WAY away from
a true administrative nightmare of a honeypot.

Would love any advice/suggestions off-list.

Regards,
Jade
