Free qmail virus scanner 1.4 software for linux

Aegis project is a virus scanner for Linux, Unix and Windows with a simple and intuitive user interface.

Aegis supports scanning of subdirectories, hidden files and .zip and .tar archive files, and drag-and-drop of files from the Nautilus file browser, or your Gnome desktop. When a virus is detected you can choose to delete, quarantine or rename the file.

Viralator is a Perl script that virus scans HTTP/FTP downloads request on a UNIX server after passing through the Squid proxy server.
Even when I implemented virus protection for my network email server we still continued to get the odd virus. Most of the viruses came from people using free webmail accounts like Hotmail or Yahoo and downloading the infected attachments to their machines or through downloading junk.
Rather than block access to the users I decided to look at how we could better protect the network. I looked at a couple of different products both comercial and free but they were either too expensive or did not meet my needs.
That is how Viralator was born. Viralator Proxy Virus Scanner is licenced under the GPL.
Viralator should work in any UNIX system that uses Apache and Squid servers. We have reports about successful instalations on:
- RedHat Linux
- Mandrake Linux
- SuSe Linux
- e-Smith Linux
- Slackware Linux
- Conectiva Linux
- Debian Gnu Linux
Supported Redirectors:
- Squirm
- SquidGuard
- Jesred
Supported Virus Scanners
- AntiVir
- AVP
- RAV
- Inoculate
- Sophos Sweep
- McAfee
- Trend
- Clamav
- Bit Defender (free edition)
The original concept for Viralator came from the Viromat project. Without Viromat the Viralator project would not have had a starting point. We can also thank Ralph Meyer for badgering me into releasing the script under the GPL.
Enhancements:
- Parenthesis are included on the regular expression used to validate URLs.
- The character set checking step, which was not working before last patch released, has been fixed.

ScannerDaemon is the virus scanner of the OpenAntivirus project. You can send a filename to it via simple TCP and it will scan the file for viruses and tell you if the file is infected or not.
The ScannerDaemon listens on localhosts port 8127 for absolute filenames and absolute directorynames. It scans the files/all files in the directory and reports OK if no virus has been found or FOUND: if a virus has been detected.
You can start the ScannerDaemon simply by typing:
java -jar ScannerDaemon.jar
If you did not forget the Credo-files, it should come up and listen on port 8127. You can also give the name of the directory as a command-line parameter, like
java -jar ScannerDaemon.jar -credo.directory
Enhancements:
- Adaptions to new listener and filter scheme
- Bugfix: allow more than one signature file in one credo file
- Bugfix: close files used by UPXFilter
- Bugfix: wrong failure transitions
- Improvement: less memory consumption for nodes
- Improvement: UPXFilter scans uncompressed and compressed file

Parallel Network Scanner provides a fast network services scanner.
pnscan is a scanner for TCP network services. It uses multithreading to increase its speed.
pnscan tries to be smart as to how many threads to start - it will dynamically start only as many as is needed to make progress in the scan - up to a maximum either as specified with the "-n" command line option, or 8 minus the maximum number of available file descriptors (pnscan tries to increase
it to the max limit automatically) - or any internal limit on the system (Linux normally only allows 256 threads).
Host ranges can be specified both as a CIDR - network name or IP address / mask bit length and as a range. When using CIDR notation - the first and last address is ignored (normally used for broadcasts)
Some examples:
192.168.0.0/24
192.160.0.1:192.160.0.254
arpanet/8
USAGE - EXAMPLES
# Scan network 192.168.0.0/24 for SSH daemons on port 22
pnscan 192.168.0.0/24 22
pnscan 192.168.0.1:192.168.0.254 ssh
# Scan hosts 192.168.10.34 ... 98 for IDENT servers, max 8 threads
pnscan -n8 -w"VERSION" 192.168.10.34:192.168.10.98 113
# Scan host 127.0.0.1 for WWW servers on all ports
pnscan -w"HEAD / HTTP/1.0rnrn" -r"Server:" 192.168.0.32 1:65525
pnscan -w"HEAD / HTTP/1.0rnrn" -r"Server:" localhost 1:65525
# Send binary data and expect the binary sequence FF 00 FF on port 145.
pnscan -W"05 5A 37" -R"FF 00 FF" 192.168.0.32 145
# Scan for Roxen servers and print the whole Server-line
pnscan -l -w"HEAD / HTTP/1.0rnrn" -r"Roxen" localhost 1:65525
# Scan for pidentd servers and try to locate the version
pnscan -w"VERSION" 192.160.0.0/24 113
# Scan network arpanet/24 for daytime servers and sort them IP-numerically
pnscan arpanet/10 daytime | ipsort
# Read host (&port) lines from stdin and scan the selected hosts for SSH
echo 192.160.10.11 ssh | pnscan -v
echo 192.160.10.12 | pnscan 22
Enhancements:
- pnscan.sgml Added the other options implemented in pnscan.c.
- pnscan.c: Modified the threads startup code to dynamically only start as many threads as is needed.

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.
