Hi Kent Ernia!
These are not really text files. These are scripts, i.e. executables. But, in order to allow them to execute, you have to change the permission of the file first!
Here's how it goes:
> chmod 751 rc.firewall
> chmod 751 rc.flush-iptables
BTW, I personnally suggest you to rename the files from *.txt to * , in order to keep track that they are not text files!
To use them, simply type:
in the directory where the files are and it will execute.
For the question of where to put them, well, this I don't know. There must be some documentation on this website, but I am really not an expert in firewall!
Hope this helps!
