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

./configure

make



cd /opt

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.

In this article, we will see what is trunk, tags or branches in SVN and understand difference between trunk, tag and branch. In short, when you first upload your project to SVN it creates a trunk, It's analogous to trunk of tree. this trunk forms the main development line. When multiple developer work on different functionality of project they usually create branch from trunk and after successfully completing that functionality, they usually merge there changes to trunk. On the other hand tag is usually used to create read only snapshot of either trunk or branch, which has been released, for future use. You can think tag as stable snapshot of code at any point, and can be used to as backup or restore. Let's see difference between branch, trunk and tag more detail in next section.
