SecPoint.com Port scanner http://www.secpoint.com/Multi-Threaded-TCP-Port-Scanner.html pscan is a multithreaded TCP Port scanner with possibility to scan any range of TCP ports on any IP address. It has both Connect and Syn scan features. History: -------- ## 1.0 initial release ## 1.1 you could use not only port range, but single ports and port lists (check -p option) ## 1.2 default port list is now not 1-1024, but is a list of frequently used ports; duplicates check ## 1.3 added more default ports. ## 2.0 - Added option -s for Syn scan. - Scanning made faster thanks to Syn scan - Added even more default ports - Improved error handler for Syn scan - Improved text output - Fixed minor bugs: - changed pathname to oui.txt and port-numbers.txt files - added missing call to cleanup function WSACleanup A new branch of the program has been created to support Syn scan. Syn scan was necessary because under some circumstances of heavy load, the Connect scan can hang routers. Syn scan is multithreaded and uses the standard library pcap on Unix/Linux operating systems. Please be aware that Syn scan requires a higher level of authorization, if compared to connect sockets: in Unix/Linux pscan requires root privilege. In some operating systems, Syn scan is performed using connectionless "raw" sockets, therefore the usage of pscan is subject to possible restriction to the usage of raw sockets in such operating systems. With Syn scan, option -w is not used because the program does not use connected sockets, so it doesn't have to loop reading a socket until the timeout is reached. The receive function doesn't have to poll over a number of sockets, but simply reads the packets passing through the network card, for all ports, and displays the message of "open port" when the packet coming from the remote IP contains the information that the remote port is open. For the same reason, options -a and -n are not used. The first one because packets sent to closed ports are simply not being replied to, so they cannot be counted; the second one because the function that reads packets is one, and performs this by reading packets from the network card, not from multiple sockets. Description: ------------ This tool could be used to scan ports of certain IP. It also could describe each port with standard name (well-known and registered ports). To make simple start run it as ./pscan IP and you will get a list of the most frequently used ports of IP scanned. But you could choose some options for scan. ./pscan IP [options] Options: -------- -p <ports> Could be used like: -p start-end (-p 130-445) -p port (-p 137) -p list (-p 135,137,139,445,1024) By default (without -p switch) tool will make best assumptions and scan frequently used ports. Those include ports 1-2000 and our special selection to make scan more efficient and quick at the same time. -s Performs a Syn scan. Default is Connect scan. With Syn scan, -n -w and -a are not used -n <inst> default: -n 10 number of simultaneous instances of scan. More instances - higher the speed, but higher system resources. Only for Connect scan. -w <time> default: -w 1000 Max waiting time for each port in milliseconds. Only for Connect scan. -a Report all ports (OPENED, CLOSED and TIMEDOUT). By default you will see only OPENED ports reported. Only for Connect scan. -r Resolve ports to known services. There is a file port-numbers.txt, it will be used to print name of well-known and registered ports. This file should be in CURRENT directory! -M MAC lookup of remote IP. Arp system tool used to check for MAC. -h Hide on-fly port displaying (display report at the end) You also could add > log.txt or >> log.txt to the command to get output in the file: ./pscan <IP> [...] > log.txt this will create or re-create log.txt ./pscan <IP> [...] >> log.txt this will append to log.txt --------------------- www.SecPoint.com Team Check for more free security scan tools at http://www.secpoint.com Try port scanner http://www.secpoint.com/free-port-scan.html and free vulnerability scan at http://www.secpoint.com/free-vulnerability-scan.html Free windows shares scan tool also available at http://www.secpoint.com The Portable Penetrator - http://www.secpoint.com/portable-penetrator.html The Cloud Vulnerability Scanner http://www.secpoint.com/cloud-penetrator-web-vulnerability-scanner.html
