Comments on: A DHCP Server in PHP, why not? http://angelo.dinardi.name/2009/09/09/a-dhcp-server-in-php-why-not/ Tue, 09 Mar 2010 02:56:08 -0800 http://wordpress.org/?v=2.8.4 hourly 1 By: osearth http://angelo.dinardi.name/2009/09/09/a-dhcp-server-in-php-why-not/comment-page-1/#comment-1990 osearth Tue, 16 Feb 2010 08:37:27 +0000 http://angelo.dinardi.name/?p=131#comment-1990 Great work. I love PHP and having everything written in it is terrific. I need a DHCP server sometimes like when i plug my network drive directly into my Gigabit NIC This little script could be quite handy. You definately have a solid start. I've always wondered about DHCP and now i can learn lots about with the language I have 12 years exp with. **If people or the original authoer want to put feature requests in comments here or http://github.com/adinardi/phpdhcp/issues and i'll do my best to try help implement them. I never heard of git:// or a phpdhcp server s you helped learn 2 new things today :D Now i just need to download the actual package... Great work.

I must admit I haven't tested it yet, but it sound like exactly the thing I need - a basic framework for allowing PHP to "parse" DHCP requests. And here's the (potential) use it can be put too... I have written a (very much work in progress) provisioning server, designed to be used with IP telephone handsets but i suppose it could really be used with anything that requests a configuration file. The body of this server is written in PHP - orginally running under an Apache server. Then I was asked to make this work with a phone that only supports FTP/TFTP for provisioning purposes. After much hunting on the internet, I was unable to find an FTP server that could adequately create files dynamically on the server side as they are requested, so I did a similar thing to the process described above, and spent a weekend building a rudimentary FTP server in PHP, so I could use the same routines I had written to be used over HTTP. The next weekend I got bored, and did the same thing, only this time building an HTTP server that is pure PHP, and does not require Apache/IIS... Slightly pointless I know, but I want the application to be as standalone as possible. Also, this removes the added complication of having to write some very complex mod_rewrite rules to distinguish between devices (and reorganise Polycom's bloody stupid directory layout for the provisioning data). Then I realised the majority of such devices will use DHCP option 66 to determine where the boot server can be found, but how do you only respond with option 66, not a full configuration? And how do you only respond to the devices in the database, and not every DHCP request you recieve? Using this, thats how... :-) This is brilliant – exactly what I was looking for!
