what is the difference between OS firewall and software firewall ?
i searched a lot but i didn't find a good answer any idea please?
An OS firewall is the built in one that comes with your OS like Windows Firewall.
A software firewall is one that you buy separately, such as Norton Firewall or something like that.
I would have expected the question to be what the difference between a hardware and software firewall are.
An OS firewall is the one that comes with your OS like Windows Firewall.
A software firewall is one that you download separately, such as Norton Firewall...

I have a windows computer and connect to Linux on a remote server for my experiments. I want to use an easy interface software from windows to my Linux server (ubuntu 18.04). Can you give some tips on how to increase productivity in such a workflow?
Putty is fast, but AFAIK, does not support tabs, you will have to open different windows for different tasks, unless you use a terminal multiplexer like screen.
Try Mobaxterm and see if you like it. It is free, and supports multiple tabs, very handy for a single session.

I would like to set up a VPN server, however it means ipv4 forwarding. Is it possible to set up a VPN without shutting down web services or should i use 2 separate servers ?
Thanks for reading ;)
Setting up a VPN server should not affect your web services. The only limitation is that you cannot use an HTTP(S) port (80 or 443), which I personally find practical (I have already seen Wi-Fi hotspots blocking all the ports except 80 and 443). However, if you get along with another port, you will do fine.
There is a good article about setting up an OpenVPN server on Debian Wiki (here). I have managed to set up the server using only this article.
Wishing you good luck.

I was looking at how windows provides tools like this called Remote Desktop Connection. Then I wondered, how would of this been accomplished. First most likely a socket connection is made between the two computers, but then how is a usable session opened. How could I do this in Java or Python?
My goal is to make one of these for connections over the internet protocol.
Research the protocol RDP which underpins the remote desktop connection support. Libraries exist to assist in using RDP in many different programming languages when you get to that point.

I want to test some keyloggers in order to see how they work.
If my host OS is clean, and I install the keyloggers on a guest OS running in VirtualBox, will the keylogger be able to log the keystrokes and screenshots in the HOST OS?
I think I know the answer to this question but I just want to make sure.
Unless your VMs are broken, key/screen-loggers will be fully contained in the VMs and will gain no access to the host OS keyboard/screen data that's outside of the VM.

I am looking for help on getting IPv6 to my Xen domU's. I currently have one 6in4 tunnel from HE for each guest and would like to consolidate that to one on the dom0. But I am not set on that-- I am completely open to suggestions.
Based on my research both here and on Google, I am not finding anything great. For what it is worth, the dom0 is running Centos 5.8 and Xen 3.0.
Sounds good to me. Set up radvd on the dom0 to advise the routable /64 they give you and have the domUs get an address from it.
