Hello there,
I am trying to modify my Firewall over Linux and am using JNetFilter with
libiptc.so Version 1.3.5
When I try to run a small programm to simply print out the chains that
exist, i reveive the error below.
I have no clue that this could mean. I can create chains without any
problem, but when i run the following method,
I reveive this error. Even the test.sh that is included in JNetFilter does
not work.
public static void main(String[] args){
try{
Table tabel = new Table("filter");
Iterator it = table.iterator();
Chain c;
while (it.hasNext()){
c = (Chain)it.next();
System.out.println(c.getName());
}
}catch (Exception e){}
}
Has anyone a Idea what the problem is an how i can fix this?
Thanks,
Alexander
