HOWTO Netcat on Ubuntu Desktop 12 04 LTS

Netcat is a featured networking utility which reads and writes data across network connections, using the TCP/IP protocol.



It is designed to be a reliable "back-end" tool that can be used directly or easily driven by other programs and scripts. At the same time, it is a feature-rich network debugging and exploration tool, since it can create almost any kind of connection you would need and has several interesting built-in capabilities.



Step 1 :



sudo -sH

cd /opt



wget http://garr.dl.sourceforge.net/sourceforge/netcat/netcat-0.7.1.tar.gz



tar -xvzf netcat-0.7.1.tar.gz

rm netcat-0.7.1.tar.gz



cd /opt/netcat-0.7.1

./configure

make



cd /opt

mkdir /opt/netcat

cp /opt/netcat-0.7.1/src/netcat /opt/netcat/

rm -R netcat-0.7.1/



Step 2 :



To run it.



sudo -sH

cd /opt/netcat

./netcat -h



Remarks :



Please do not delete the built-in netcat-openbsd as it will also delete the ubuntu-mininal package at the same time. Your compiled netcat is different to the built-in one.



Thats all! See you.
