netfilter scan detect
Hello,

i search a solution to detect scan port, i find psd patch, but now with
the last version of iptables, psd patch is not supported. An over
solution is possible?

Thanks you.

Try to use 'stealth' module from GRsecurity patchset.
It will detect stealth scans, but you need patched kernel and iptables.
