Virtual Services IPQ
About VServ IPQ
Virtual Services IPQ, or VServ IPQ for short, is a Java
library that wraps the Linux netfilter/iptables libipq library
(http://www.netfilter.org/). It allows you to
intercept packets that pass through Linux iptables chains from
Java code. You can mangle the packets and reinject them into the
iptables chains.
License
VServ IPQ had to be released under the GPL because libipq is a GPL'ed library.

The Netfilter class was renamed to IPQHandle between releases 0.6.2 and 0.6.3. VServ TCP/IP is required to compile the PacketMonitor example.
Also, on x86_64 and architectures other than 32-bit x86, your libipq.a must be compiled with -fPIC so that libvservipq.so can link with it properly. This is not a problem on 32-bit x86 architectures, but on x86_64, linking against a non-PIC libipq.a will fail. Note that libipq.a is not built with -fPIC by default, requiring you to rebuild the library either by patching the source RPM or other package from your Linux distribution or by compiling the iptables source yourself with:
