Grand Prix du Canada 2004

Second missed GP of this season. Reasons :

  • No Star Sports. Kill Cable TV chap tomorrow. Seems all of ICE TV's subscribers didn't get it.

  • Was busy with iptables, managed to setup a pretty decent one with louiswu's help.

Finally got Passive mode FTP working flawlessly using conntrack. Was *the* pain in our arses for quite sometime. He's decided to name our iptables tool "Flint". Ah well, what's in a name? :D

PS : Off to watch England Vs France, Euro 2004.

Okies here goes, iptables is the name of the packet filtering system used in Linux. In other words it is a Firewall. For more info on what a Firewall is, check out [1] & [2].

[3] FTP or File Transfer Protocol is basically used to transfer files over the Internet. The files are stored on the server & if you need a file, you connect to the server to get the file. Now usually there are standard "ports" thru which this happens. Just like your Serial port (where your Modem is connected at the back of your comp) & Parallel port (Printer), ports on the internet are basically an "interface" for data communication to happen. Common things like your HTTP happen on a standard port 80. For example, when you type in http://www.livejournal.com, your browser connects to the web server at livejournal.com on port 80.

Similarly, FTP uses port 21. There are two modes of FTP, Active & Passive. Active happens over the standard port(s), while Passive may happen over any of the TCP Ports above 1024. Because of the way Passive mode FTP operates, its a bit difficult to set firewall rules to allow the same :)

Finally, louiswu & myself are planning to write up a tool to make setting up iptables easier & the first release version is going to be called Flint.
