PORTSCAN(1)

NAME
PortScanner - TCP port scanning program by Tennessee Carmel-Veilleux

SYNOPSIS
portscanner [-v] [-vv] [-b port] [-e port] [-bm id] [-em id] [-a] [-s] [-]? [-h] [-i] [address]

DESCRIPTION
The portscanner utility scans for listening TCP ports on a remote host and returns a list of the ports it finds through STDOUT

Options are:

-v -vv
    Both those options are used to select the level of verbosity for the output of portscanner. -v is level 1, -vv is level 2. Default is level 0, in which only the address followed by the ports followed by a pound are sent to the output, each on a different line. Level 1 introduces some more information, and level 2 is the level to use if a human being is going to read the output. Level 0 is well suited for input to an interface, as it only contains bare information that can be easily processed by a simple parser.

-b  Sets the port at which portscanner starts its scanning. Default is 1.

-e  Sets the port at which portscanner ends its scanning. Default is 1024.

-bm Sets the machine ID in the subnet at which portscanner starts scanning if it is in subnet-scanning mode.

-be Sets the machine ID in the subnet at which portscanner stops scanning if it is in subnet-scanning mode.

-a  Argument present if you want portscanner to scan the entire subnet containg the address.

-s  Argument present if you want portscanner to use strobe-scanning. Strobe scanning is a method of scanning that ONLY scans for ports present in your /etc/services file. It is useful if you want fast scanning over only the commonly used ports.

? -h
    Prints out a message containing the description of the arguments that portscanner can use.

-i  Prints out miscellaneous information about portscanner including date of compilation and version.

    portscanner will scan ONLY for TCP ports, as UDP ports use a different scanning method. The output consists, in level 0 of verbosity, of the following informations: line 1 contains the IP address of the scanned system, the following lines are read and contain the numbers of the ports that have been detected as listening sockets. The interface program should stop reading ports for the current address when the pound ('#') sign is read. Next records follow is subnet-scanning mode is enabled.

HISTORY
The portscanner utility was created by Tennessee Carmel-Veilleux (veilleux@ameth.org) in 1998. It is now version 1.2
