| My mod_rewrite guide |

So I got bored and since I'm doing a lot of mod_rewrite work lately, I have decided to do a little mod_rewrite guide. If anyone wants something done I can try to do it.. but for now I will just explain what things do. The syntax of mod_rewrite is almost like sendmail.. but once you understand it you can do some really great things.
So we'll start off with just a common use for mod_rewrite. I always keep all my images in like /var/www/html/images. So this will show a default error image not found image instead of that nasty broken image box with the X in it. So you want to create a .htaccess file in the /var/www/html/images dir. Then place the following lines in it.
Code: RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.+) /images/404.png
So the first line just tells apache to turn on mod_rewrite.
The second line is a conditional statement. It says move on to the next line if the requested file does not exist. So the condition is the !-f. The -f checks if the request is for a file. So the ! in front of it is a common programming practice and that basically negates what comes after it. So the total line means if the request is for a file that does no exist in the directory
Then the last line says take any input and replace it with /images/404.png.
So if i have this in html
Code: <img src=/images/bla.jpg>
if there is no bla.jpg in the images dir it will show a 404.png in its place. Don't worry about image format differences. The browser will hande it.
more to come when i get bored.

| How to upgrade from FC2 to FC3 |
|

Hey, here is a neat way to upgrade from FC2 to FC3 without doing a clean install, but using apt-get.
First you must find the apt repositories from somewhere, I used this page right here: Fedora Apt/Yum Repositories list.
Now go to your server and doing as root and backup the apt sources.list
Code: cd /etc/apt
cp sources.list sources.backup
Now, edit the sources.list. Remove everything inside and replace with the apt links from the Fedora Apt/Yum Repositories list.
Save and exit, then do an update and upgrade with apt-get.
Code: apt-get update && apt-get dist-upgrade -y
This will take a while :)When finnished, reboot and you will have Fedora Core 3.
I dont know if this is a good way for doing it but it worked for me, so far so good.

to avoid brute forcing on your ssh, limit connections to it using iptables
Code: iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A INPUT -p tcp --dport 22 -m limit --limit 2/minute --limit-burst 1 -j ACCEPT
iptables -A INPUT -p tcp --dport 22 -j REJECT --reject-with tcp-reset
please note if the above doesnt work for you then check if lokkit is running (fedoras/redhat's firewall)
disable it if it is and use iptables to control your ports instead
Quote:iptables-save
will list any previously saved iptables rules.

Well, I'm a noob. I went to apt-get.com and added some source lists to my source.list file. How many is normal to have? I had about 20, but after receiving some errors from apt-get update I removed the ones causing problems. So I have about 15 now. I am wondering if anyone has any good tips for making a source list file.

Hi,
I have been wondering if anyone knows how to monitor users on the network via vnc
so you can login into there screen and watch what they are doing?
I looked at kdenetwork3-vnc which I was able to login on a users session and watch what they
were doing, I was also able to type and control there mouse. It would be better if I could of
disabled them using the mouse and keyboard.
