Free to scan software for linux

Login Scan fusion provides an adaptation theme from kdm fusion.

This is a adaptation of the theme for kde "fusion for GDM.

Multiscan is a tcp port scanner for console which allows you to scan a range of IP addresses. Each IP address is pinged before it is scanned. It is also possible to scan just known ports, and to scan them in a random order. Feel free to send me a mail at coldn@gamearena.net

Installation:
Grab the package from http://sourceforge.net/projects/multiscan/
tar xzvf multiscan-X.X.tar.gz
cd multiscan-X.X
./configure
make
make install (optional)

qscan is a sendmail queue scanner designed to scan all incoming email for file attachments and rename any offending file attachments. File attachments are not scanned for viruses, but allow you, the system administrator, to rename either some or all incoming file attachments to .txt file extension. The original filename is renamed to "filename~doc" for example, so that the end user can rename the file once it is scanned for viruses.

This program is by no means a perfect solution, but if security is properly maintained at your organization it will allow you much greater flexibility at stopping any possible email virus outbreaks. Therefore, you will need to maintain current anti-virus software on your workstations in case a virus infected file is emailed to one of the stations and they rename and execute that file.

C::Scan is a Perl module that can scan C language files for easily recognized constructs.

SYNOPSIS

$c = new C::Scan filename => $filename, filename_filter => $filter,
add_cppflags => $addflags;
$c->set(includeDirs => [$Config::Config{shrpdir}]);

my $fdec = $c->get(parsed_fdecls);

This description is VERY incomplete.

This module uses Data::Flow interface, thus one uses it in the following fashion:

$c = new C::Scan(attr1 => $value1, attr2 => $value2);
$c->set( attr3 => $value3 );

$value4 = $c->get(attr4);

Attributes are depending on some other attributes. The only required attribute, i.e., the attribute which should be set, is filename, which denotes which file to parse.

All other attributes are either optional, or would be calculated basing on values of required and optional attributes.

ICMPScan scans the specified address, or addresses, for ICMP responses.

Usage:

icmpscan [ -EPTSNMAIRcvbn ] [ -A address ] [ -f filename ] [ -i interface ] [ -r retries ] [ -t timeout ] target [...]

Options:

-i, --interface
Listen on the specified interface. If unspecified, icmpscan will examine the routing table and select the most appropriate interface for each target address.
-c, --promisc
Put in interface into promiscuous mode. As this option increases the load on the system in general, it should only be used if spoofing of source packets address is enabled with the "-A" option.
-A, --address
Specify the source IP address of generated packets.
-t, --timeout
Specify the timeout, in milli-seconds, before retrying.
-r, --retries
Specify the number of attempts to elicit a particular ICMP response.
-f, --file
Read target list from the specified file.
-E, -P, --echo, --ping
Check of ICMP Echo responses.
-T, -S, --timestamp
Check for ICMP Timestamp responses.
-N, -M, --netmask
Check for ICMP Netmask responses.
-I, --info
Check for ICMP Info responses.
-R, --router
Check for ICMP Router Solicitation responses.
-v, --verbose
Increase the output verbosity.
-B, --debug

Target Specification

The simplest case is listing single hostnames or IP addresses on the 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". There is also 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 192.168.*.* by specifying "192.168.*.*" or "192.168.0-255.0-255" or even "192.168.1-50,51-255.1,2,3,4,5-255". And of course you can use the mask notation: "192.168.0.0/16". 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.

Examples:

The following example checks the first 16 addresses in the 192.168.1.0/24 netblock for all ICMP responses. The scan speed is increased by lowering the timeout value and setting the number of retries to 1:

> icmpscan -t 500 -r 1 192.168.1.0-16
192.168.1.0: Echo (From 192.168.1.17!)
192.168.1.0: Address Mask [255.255.255.0] (From 192.168.1.17!)
192.168.1.7: Echo
192.168.1.7: Timestamp [0x03ab2db0, 0x02d4c507, 0x02d4c507]
192.168.1.7: Address Mask [255.255.255.0]
192.168.1.8: Echo
192.168.1.8: Address Mask [255.255.255.0]
To display failed probes, increase the output verbosity:

> icmpscan -v 192.168.1.1
192.168.1.1: -- No response to Echo request --
192.168.1.1: -- No response to Timestamp request --
192.168.1.1: -- No response to Netmask request --
192.168.1.1: -- No response to Info request --
192.168.1.1: -- No response to Router Solicitation request --
Individual ICMP types can be checked for by listing their corresponding flags on the command line:

> icmpscan -v --echo --netmask 192.168.1.7
192.168.1.7: Echo
192.168.1.7: Address Mask [255.255.255.0]

mdns-scan is a tool for scanning for mDNS/DNS-SD published services on the local network. mdns-scan issues a mDNS PTR query to the special RR _services._dns-sd._udp.local for retrieving a list of all currently registered services on the local link.
mdns-scan is not a good mDNS citizen since it queries continuously for services and doesnt implement features like Duplicate Suppression. It is intended for usage as a debugging tool only.
mdns-scan is incomplete since it doesnt resolve mDNS services for you - it just dumps their PTR RRs. To understand these records you need minimal knowledge of DNS-SD and how it works.
mdns-scan does not terminate on its own behalf. It scans for services continuously until the user kills it by pressing C-c.
mdns-scan does not rely on a local mDNS responder daemon. It has no dependencies besides the GNU libc. It has been tested on Linux only.
mdns-scan does NOT scan for local mDNS enabled hosts or A/AAAA RRs, it scans for DNS-SD registered services, nothing else.
Enhancements:
- Add man pages
- Improvements to the Debianization

AntiVirus Scanner is an anti-virus scanner for Endeavour Mark II that uses the ClamAV library (libclamav).

AntiVirus Scanner allows you to create a list of scan items for frequently scanned locations and features easy virus database updating, all in a simple GUI environment.

Antivirus Scan with F-Prot is a simple servicemenu for konqueror that allows to scan single or multiple files and folders using the F-Prot Antivirus. Antivirus Scan with F-Prot shows the result of the scanning in a textbox using kdialog. It can also show the progress of the scanning in a terminal.
I hope you may find it useful.
Comments or/and translations are welcome.
TO INSTALL: extract the content of the tarball and copy the file f-prot_virus_scan.desktop into ~/.kde/share/apps/konqueror/servicemenus (just for your user) or in /usr/share/apps/konqueror/servicemenus, /opt/kde/share/apps/konqueror/servicemenus... etc, depending on your distro, to make it system-wide.
This is only the service-menu, you need to have F-Prot antivirus installed on your system.

- Added Danish translation by Kefeus
