Hello, poking around at the website I see the 1.2.8 is out. In the 'history' (http://www.iptables.org/downloads.html#cvs) it appears there is a patch-o-matic entry between 1.2.7a and 1.2.8. To use 1.2.8, do I need to do anything special? I currently have the 2.4.20 w/ebtables patches. Also, when mangling the contents of a packet (including payload size), is there anything special you need to do aside from recomputing IP and TCP/UDP checksums? Lastly, are there any good references for userspace apps? There is a ton for the netfilter, but was looking for more in the way of userspace concepts & activities. Thanks! -Scott __________________________________________________ Do you Yahoo!? The New Yahoo! Search - Faster. Easier. Bingo http://search.yahoo.com
