Extracting the gateway IP address is straightforward:
$ip = $_SERVER['REMOTE_ADDR'];
To obtain the hostname of the gateway IP address just do the following:
$hostname = GetHostByName($_SERVER['REMOTE_ADDR']);
To get the local IP address of your user can sometimes be useful too. Here’s how:
$localip = $HTTP_SERVER_VARS['HTTP_X_FORWARDED_FOR'];
A nice trick for having screen open a new tab in the same directory as the one you’re currently in. To use it add it to your .screenrc
# Open new window in current dir.
bind c stuff "screen -X chdir \$PWD;screen^M"
bind ^c stuff "screen -X chdir \$PWD;screen^M"

sudo apt-get install python-software-properties

Hi, I’m as we speak working on the first draft of Joornal which will be a re-written blogging script to replace this one. There’s no question that permalinks will become a feature of this. Watch this space.
