How to attract traffic to a honeypot

If anything, there are several different types 'prey' you can attract. First, there are tons of bots out there automatically running port scan on different ip ranges to enumerate vulnerable services. So, to attract bots and such, it's important to look like a "old and injured prey." Run as many vulnerable services as possible to attract attacks from those bots. One caveat is some providers to upstream blocking. So, if you're running your honeypot on such a provider network, you may not see these scans.

If you want to be subject to "script kiddie" type attacks, then posting your IP on boards as well as a massive flaming campaign on boards/IRC rooms will help you attract attention.
