Open Source Software and Hardware Inventory Management Software

I’m looking for good open source software and hardware inventory management software. A quick search on sourceforge returned following inventory management system / software management apps:

=> OCS Inventory NG, Open Computers and Software Inventory Next Generation is an application designed to help administrator keep track of the computers configuration and installed softwares. Low network traffic HTTP communications between agents and server. I’m currently testing this software and I will update all of you about my results.

Other old (outdated) softwares

=> PcInventory Web-based system to track the Pc and the installed peripherals.

=> phpMyInventory is a web-based hardware, software, and peripheral inventory system using PHP & MySQL. Currently stable on PHP version 4xx only!

=> Windows Inventory. A Computer Hardware and Software Inventory system. Based around wmi, vbscript, mysql & php. Expandable via modules to include software distribution, remote control, event viewer, disk monitoring, etc.

Most of these software are outdated. Basically, I need to keep inventory for following items

  • Open source inventory asset management software
  • Should able to track inventory
  • Auditing feature
  • Inventory of equipment owned and leased (including lease expiry)
  • Software inventory for both Windows and UNIX systems
  • Import / Export function etc

Do you have any recommendations for me? Please add them in the comments.

Linux Iptables block all network traffic

You would like to block all network traffic using iptables firewall under Debian GNU/Linux. This will block all incoming and outgoing traffic including Internet aka ADSL/ppp0 and it is highly recommend. The logic is block everything and allow only required traffic. This can be done with four simple commands:

# iptable -F
# iptables -P INPUT DROP
# iptables -P OUTPUT DROP
# iptables -P FORWARD DROP

Please do not enter above command over remote ssh login session.
