Running fsfuzzer 0.7 on Ubuntu or Debian

Jannich Brendle on June 16th, 2010

fsfuzzer is a filesystem fuzzer tool that does stress testing of various filesystems in a reproducible and logged way. This tool creates initial valid filesystem images and then manipulates their binary format and structure for detecting flaws/bugs/design problems in the parsing/handling code for that particular filesystem.

To install and run fsfuzzer on ubuntu or debian, open a terminal and run the following command:

cd ~
apt-get install libattr1-dev build-essential gfs2-tools mtd-utils dosfstools reiserfsprogs genromfs squashfs-tools xfsprogs ecryptfs-utils
wget http://people.redhat.com/sgrubb/files/fsfuzzer-0.7.tar.gz
tar xzf fsfuzzer-0.7.tar.gz
rm fsfuzzer-0.7.tar.gz
cd fsfuzzer-0.7
./configure
make
./fsfuzz --help

Which should respond with something along the lines of

./fsfuzz cramfs|ext2|ext3|ext4|swap|msdos|vfat|xfs|jffs2|reiserfs|romfs|ecryptfs

Happy testing everyone. :-)

Installing HTTP AntiVirus Proxy (HAVP) to protect your computers from viruses

Jannich Brendle on June 15th, 2010

Protecting your (windows) computers from viruses online is more important now than ever. That’s why the folks at server-side.de have developed HAVP, which is a proxy server that continuously scan incoming traffic for known viruses. It uses ClamAV, which is an open-source anti-virus toolkit for UNIX-like operating systems. ClamAV is designed for scanning emails for viruses, but it works equally well scanning many other mediums for viruses.

To install HAVP on Debian or ubuntu, simply use this command:

sudo apt-get install havp; sudo freshclam; sudo /etc/init.d/havp restart

To use it, set your browser to use the proxy server at the IP of the computer you’ve installed HAVP on, port 8080, like http://192.168.1.1:8080, where 192.168.1.1 is the IP of the server running HAVP.

To verify that everything is working, go to any or all of the following: http://www.eicar.org/download/eicar.com http://www.eicar.org/download/eicar.com.txt http://www.eicar.org/download/eicar_com.zip http://www.eicar.org/download/eicarcom2.zip. The download should be blocked by HAVP. If you are running this on a company network, you can change the look of the HAVP’s warnings by editing the files in /etc/havp/templates/ to include further information.
