Web Submission and Review Software is a Web-based system that is used for the submission and review of papers to academic conferences. Web Submission and Review Software provides support for the entire life-cycle of the conference review process.
One of the goals of this software was to make administration as easy as possible. In particular, you never need to run scripts etc. In principle, to install this software you just unpack the zip file in some directory in your web tree (call it the BASE directory), point your browser at that directory and off you go.
I will very much appreciate any comments that you can give me regarding this software.
Enhancements:
Changes to chair/administrator interface:
- Added Undo/Redo link to the administration page
- Re-implemented the voting mechanism to allow multiple concurrent ballots
- Let the chair play with assignments of submissions to reviewers before these assignments are visible to the reviewers
- Let the chair manage PC membership, Edit review guidelines and setup votes also during the submission phase
Changes to reviewer interface:
- Allow reviewers to login to the site (and vote in ballots if any) also during the submission phase
- Added support for batch upload of reviews in a scorecard file
- Backup old versions of reviews and let reviewers browse the old versions of their reviews (this is useful, e.g., if they overwite somethign by mistake)

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 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.
