Nmap::Scanner is a Perl module to perform and manipulate nmap scans using perl.

SYNOPSIS

Perl extension for performing nmap (www.insecure.org/nmap) scans.

use Nmap::Scanner;

# Batch scan method

my $scanner = new Nmap::Scanner;
$scanner->tcp_syn_scan();
$scanner->add_scan_port(1-1024);
$scanner->add_scan_port(8080);
$scanner->guess_os();
$scanner->max_rtt_timeout(200);
$scanner->add_target(some.host.out.there.com.org);

# $results is an instance of Nmap::Scanner::Backend::Results
my $results = $scanner->scan();

# Print the results out as an well-formatted XML document
print $results->as_xml();

# Event scan method using *new* easier way to set scan options.

my $scanner = new Nmap::Scanner;
$scanner->register_scan_started_event(&scan_started);
$scanner->register_port_found_event(&port_found);
$scanner->scan(-sS -p 1-1024 -O --max-rtt-timeout 200 somehost.org.net.it);

sub scan_started {
my $self = shift;
my $host = shift;

my $hostname = $host->name();
my $addresses = join(,, map {$_->address()} $host->addresses());
my $status = $host->status();

print "$hostname ($addresses) is $statusn";
}

sub port_found {
my $self = shift;
my $host = shift;
my $port = shift;

my $name = $host->name();
my $addresses = join(,, map {$_->addr()} $host->addresses());

print "On host $name ($addresses), found ",
$port->state()," port ",
join(/,$port->protocol(),$port->portid()),"n";

}

This set of modules provides perl class wrappers for the network mapper (nmap) scanning tool (see http://www.insecure.org/nmap/). Using these modules, a developer, network administrator, or other techie can create perl routines or classes which can be used to automate and integrate nmap scans elegantly into new and existing perl scripts.

If you dont have nmap installed, you will need to download it BEFORE you can use these modules. Get it from http://www.insecure.org/nmap/. You will need nmap 3.10+ installed to use all the features of this module.

TCP port scanner is a network scanner for Linux.

Installation:

1. Install - become root and gunzip/tar tcpscan-X-Y-Z.tar.gz.
2. Type ./confugure , make
3. Type install
4. Enjoy and try type tcpscan localhost
5. To get help - run tcpscan without parametres.

Usage:

tcpscan [-f] [hostname || IP_address]
tcpscan [-f] [first_IP_address] [last_IP_address]

PScan scans C source files for problematic uses of printf style functions, such as "sprintf(buffer, variable);" instead of "sprintf(buffer, "", variable);". These sort of problems have been the source of many security holes. PSCan looks for them, and nothing else. It does not make your program safe, but it can help to make it safer.

See the Format bugs post to BUGTRAQ for a good explanation of the security problems associated with sprintf(buffer, variable);. These security issues also currently involve being able to bypass stack protection mechanisms like StackGuard. I have submitted a paper to BUGTRAQ describing the issue.

All of these security problems can also occur with any printf-style function. It is simple to fall into the trap of misusing printf and friends, thus, the need for PScan.

What PScan cant do:

Scan for traditional buffer over-flows.
You should use a bounds-checking compiler for that.

Scan for any other mis-use of function parameters.

The functionality given by PScan is limited. Yet it may be useful. Im not going to claim its the be-all and end-all of security scanners, but it does one thing, and it does it simply, and reasonable well.

Analyzing and correcting the security breaches is up to the programmer.

Qmail-Scanner Statistics (QSS) uses the Qmail-Scanner Logfile to generate daily, monthly, and yearly statistics.
It also shows a complete list of viruses stopped by Qmail-Scanner, the top five domains from which the viruses came, as well as the countries of origin.
Enhancements:
- Now the paramters passed to the graphs are encoded with rawurlencode()
- A small correction to the index.php file to improve the result with very small log files

XSane is a graphical scanning frontend. XSane uses the SANE-library to talk to scanners. This means that XSane does not support any scanners itself.
If you have any problems or questions that are related to your scanner then please contact the author of the sane-backend that supports your scanner or for general questions contact the SANE mailinglist. Here you can find out which scanners are supported by the SANE-library.
XSane is designed for acquiring images with scanners (there are other devices like cameras and videodevices supported by SANE, but XSane is not designed for that purpose).
You can scan to file, do a photocopy, create a fax, create and send a mail and start XSane from the GIMP as gimp plug in.
Enhancements:
- Black point compensation was added to the printer setup dialog.
- A PostScript bug was corrected.
- Several bugs in the color ICM profile handling were fixed.

SANE comes from "Scanner Access Now Easy" and is an application programming interface (API) that provides standardized access to any raster image scanner hardware (flatbed scanner, handheld scanner, video and still cameras, framegrabbers, etc.).

The SANE standard is public domain and its discussion and development are open to everybody. The source code is written for UNIX (including Linux) and is available under the GPL, but commercial applications and backends are welcome.

The package contains the libraries, net support, and scanimage. The X frontends xscanimage and xcam can be found in sane-frontends.
