Qmail virus scanner 1.4
The Qmail virus scanner (QScan) is a mail filter for Qmail that scans incoming messages using the Sophos Antivirus engine. more>>
The Qmail virus scanner (QScan) is a mail filter for Qmail that scans incoming messages using the Sophos Antivirus engine, immediately rejecting infected content.
It is designed to be minimalistic, yet extremely fast and secure, and uses multiple pipes instead of the traditional temporary files and privilege separation. It works with non-native versions of the virus scanner like under OpenBSD with Linux or FreeBSD emulation.
You must create a temporary directory to extract MIME attachments, and replace Qmails original qmail-queue program with Qscan. Quick way to achieve this for the impatients :
mkdir /var/qmail/qscan
chmod 700 /var/qmail/qscan
chown qmaild:qmail /var/qmail/qscan
ln /var/qmail/bin/qmail-queue /var/qmail/bin/qmail-queue-old
Now, lets compile and install Qscan :
./configure --help
./configure [your beloved flags]
make install-strip
The last step is to replace the original qmail-queue program with our filter :
rm /var/qmail/bin/qmail-queue
ln -s /usr/local/sbin/qscan /var/qmail/bin/qmail-queue
Depending on your local configuration, it may be needed or not, but start with doing it :
chown qmaild:qmail /usr/local/sbin/qscan
chmod 6711 /usr/local/sbin/qscan
After testing, if everythings ok for you, remove the setuid bit :
chown 0:0 /usr/local/sbin/qscan
chmod 711 /usr/local/sbin/qscan

Viralator Proxy Virus Scanner 0.9.7
Viralator Proxy Virus Scanner is a Perl script that virus scans HTTP/FTP downloads request on a UNIX server. more>>
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.

POP3 Virus Scanner Proxy 0.4
POP3 Virus Scanner Proxy is a full-transparent proxy daemon which scans all mails for viruses more>>
POP3 Virus Scanner Proxy is a full-transparent proxy daemon which scans all mails for viruses using third party scanners (built-in support for AVPD and Trophie).
You have to set up a port redirection in the linux-netfilter (iptables) so that all connections from e.g. inside your office to any POP3 server outside in the world will not leave your router, but come a local port, on which POP3VScan listens. POP3VScan receives from the linux kernel the original destinations of packets (the POP3 server outside in the world) and will connect to them.
All data we receive from the client will be sent to the server, and vice versa. With a little enhancement: we parse the neccessary parts of the POP3 protocol and when an email is sent from the server, we store it into a file, invoke a virusscanner and send it if it is good, or we just replace it with a virus notification. It should be possible to use all scanners using the scannertype=basic. Also POP3VScan provides scannertype=avpd for high-speed scanning using Kaspersky Anti-Virus for Linux, every C programmer can easily adept other scan-daemons (trophie, sophie, antivir, ...).
Neither the client nor the server has to be configured, none of them will take notice that theres a mailscanner (except the client when he gets a virus notification or if he looks into the header, and the server gets our ip as source).

OpenAntivirus ScannerDaemon 0.6.0
ScannerDaemon is the virus scanner of the OpenAntivirus project. more>>
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

mdns-scan 0.4
mdns-scan is a tool for scanning for mDNS/DNS-SD published services on the local network. more>>
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

Milter-Virus 2.0.0
Milter-Virus is a wrapper that can be used with many commercial and freely available virus scanners. more>>
Milter-virus is not a virus scanner. It is a wrapper that can be used with many commercial and freely available virus scanners. Milter-Virust is written completely in C, and requires (few skills??).
It is run-able with the Milter interface, but then will only scan for "double extensions".
If you wish it to scan for more, you need at Ripmime or other tools to extract files from MIME-encoded emails. You also need a (command-line) virus scanner.
The difference between this program and the original is that this is much more configurable via the config file. The original version has the advantage that it is simpler and easier to bugfix.
Enhancements:
- This is a large update.
- Many problems in the statistik module were fixed.
- Some spam protection features were included.

Inflex 1.1.0.1RC3
Inflex is a solution to the problem of scanning emails which are passing through your server, both local and outbound. more>>
Inflex is a solution to the problem of scanning emails which are passing through your server, both local and outbound.
Inflex give to you the ability to block or pass email based on any set of tests you choose, varying from Virus scans to Email text content.
Inflex can do this because it unpacks all email sent through it in such a way that normal UNIX tests can be performed to determine the nature of the email.
The need for a system as Inflex arose out of the need to be able to tightly control and filter emails at a central location, existing scanning systems could only scan local mail.
Local mail only scanning is a serious limitation when a corporation is trying to prevent unwanted email from getting out to the world.
Inflexs ability to scan for arbitary file names and types allows administrators to react instantly to virus threats which may not yet be detectable in antivirus packages [typical
delays between virus deployment and antivirus updates can be as long as 48 hours, more than ample to cause an entire network to be crippled].
Installation:
./install.sh
Enhancements:
- Updated ripMIME engine
- Added Fedora support
- Added HBEV AV support
