I am using a Linux Cent OS box & I would like to ask you if it is possible to create a program in Java that can set TCP/IP header fields in a packet and the send it on the network. For example i would like to make a SYN scanner. Or I may need to set TOS or IHL or TTL fields in a IPv4 packet.
I haven't found method in Datagram that can do that.
Thanks in advance

You'll have to resort to native code through JNI or JNA - it's not possible using pure Java code.
