At work we have a lab network. And while one would think that the lab network would be more permissive than the corporate network, in all reality, it's less permissive. MAYBE it's the same, but I doubt it. I wanted to find out what ports were open to the outside world so I could find out how I can access any kind of server(s) at home. From the lab network, it is very easy to perform the scan with nmap. But what about the responses? I had (and still have) a web server running at the time, and while I was certain it would respond to ports 22, 80, and 443; that still leaves another 65,532 other possible ports. How do I get my server to just blindly respond to all those other ports, without having any real applications installed/running?

After much trouble, I eventually found a scapy script to do exactly what I wanted, just blindly respond to any packets on any/all ports! Read on for more details...

In this article, we go over setting up a site-to-site VPN between a Check Point Gateway and a Sophos UTM Home Edition device.

Check Point is the leader in Next-Generation Firewalls. While there can be a bit of a (steep) learning curve with their products, they are leading edge, and very powerful. The biggest downside to Check Point is cost. They are quite expensive, both in terms of products and support. But you get what you pay for, and when you pay top dollar, you really do get top product. But what about the regular Joe, home/small business owner who doesn't have that kind of cash? Or what about small, non/not-for-profit organizations?

In a bit of a panic, I moved all kinds of grub files, without fully realizing the consequences later on... In any case, I am going over the files that I do have, and noting what differences may exist. If there's anything that would cause my booting problems, it is likely the bootloader, grub.

In my ongoing desire to determine who/what/when/where/why my server had previously been compromised, I continue my analysis with the messages files and some other /var/log files.

Here I go over the following files /etc/hosts*

This works out to 3 files total.
