NAME

sweep - scans multiple hosts to determine their network status

SYNOPSIS

sweep.pl [OPTS] <IP_ADDR> [<IP.ADDR> ...]

DESCRIPTION

This script uses the nmap security scanner with the Nmap::Parser module in order to run a quick PING sweep against specific hosts. It will then inform of which hosts were active (up) and inactive (down).

OPTIONS

These options are passed as command line parameters.

-i nmapscan.xml

Runs the script using the given xml file (which is nmap xml scan data) instead of actually running a scan against the given set of hosts. This is useful if you only have the xml data on a given machine, and not nmap.

-h,--help,-?

Shows this help information.

-L ips.txt

Reads IP addresses from filename.txt to run a scan against. The IP addresses should be in the target specification format explained below.

-o output.txt

Saves the IP addresses found to be active (in state 'up') to a given file. This file contains each of the active IP addresses found, one on each line. This is useful if you wish to use the file with other programs or scripts.

-v

This runs the script in verbose mode. The more times used, the more verbose the script will be.

TARGET SPECIFICATION

This documentation was taken from the nmap man page. The IP address inputs to this scripts should be in the nmap target specification format.

The simplest case is listing single hostnames or IP addresses onthe command line. If you want to scan a subnet of IP addresses, you can append '/mask' to the hostname or IP address. mask must be between 0 (scan the whole internet) and 32 (scan the single host specified). Use /24 to scan a class 'C' address and /16 for a class 'B'.

You can use a more powerful notation which lets you specify an IP address using lists/ranges for each element. Thus you can scan the whole class 'B' network 128.210.*.* by specifying '128.210.*.*' or '128.210.0-255.0-255' or even use the mask notation: '128.210.0.0/16'. These are all equivalent. If you use asterisks ('*'), remember that most shells require you to escape them with back slashes or protect them with quotes.

Another interesting thing to do is slice the Internet the other way.

Examples:

sweep.pl 127.0.0.1
sweep.pl target.example.com
sweep.pl target.example.com/24
sweep.pl 10.210.*.1-127
sweep.pl *.*.2.3-5
sweep.pl 10.[10-15].10.[2-254]

OUTPUT EXAMPLE

These are ONLY examples of how the output would look like.

Status Check
-------------------------------------------

Active Hosts Scanned:
        127.0.0.5
        127.0.0.6
        127.0.0.2
        127.0.0.1
        127.0.0.4

Inactive Hosts Scanned:
        127.0.0.3
        192.168.0.1
        192.168.0.2
        192.168.2.4

The output of the file if using the '-o file.txt' option will look like (using the IPs from the previous example):

127.0.0.5
127.0.0.6
127.0.0.2
127.0.0.1
127.0.0.4

BUG REPORTS

Please submit any bugs to: http://sourceforge.net/tracker/?group_id=97509&atid=618345

Please make sure that you submit the xml-output file of the scan which you are having trouble. This can be done by running your scan with the -oX filename.xml nmap switch. Please remove any important IP addresses for security reasons.
