Another aspect of enumeration of hosts is the determining of TCP ports in an OPEN state, that is to say TCP ports which respond to SYN packets with a Syn and the ACK flag set, Syn-Ack. Synscan is impressively fast at determinining this via the use of two processes, one to send the Syn packets and one to listen for the responses. NB: At first start with low settings as it can impact systems if it is run too fast. The portparse utility is also a useful little tool! Should compile cleanly on IRIX, Solaris and Linux if you have libpcap installed. Licensed under the GPL version 2. If you modify this app for your own needs, i would appreciate a copy of the changes being emailed to me. Edit synscan.h to configure a few parameters before compiling. Synscan works using 2 programs.. The "synscan" tool will send SYN packets. And a second program, either synscand or sslog will listen for the resulting SYN/ACK packets to determine if ports are open. Compiling this tool will create 3 binaries: synscan - for sending SYN packets synscand - logs replies and performs protocol specific checks sslog - logs replies and shows ip:port results.
