Hello, I've tried to compile iptables and kernel 2.6.18 with some extensions I'd used with a prior kernel as they're string and psd match. Now I'm getting a little confused about patch-o-matic-ng. A lot of the extension I've seen before went out from patch-o-matic-ng (like string and psd) but they're described in base or extra. I'm getting string working but psd does'nt work. I was lookin' in an old branch psd code which was portet to 2.6.11 but it does'nt work also. Iptables prints out an "invalid size 0 != 12" on psd match. Any hints? Thanks in advance for your help. Best regards Chris
