OpenWrt GUI: preview is released

26 Oct, 2005 - 2 minutes
Update: this document is officially obsolete — alpha is released! Finally I released a preview: /webui-0.1-pre-alpha.ipk! I included two information applets and a simple network configuration applet. I think it would be enough for a proof of concept. I borrowed heavily from nbd’s webif. So if it works for you, it is due to his OpenWrt expertise. If it doesn’t, it is my fault. Both webif and webui can be installed side by side:

OpenWrt GUI: preview is ready, packaging

24 Oct, 2005 - 1 minutes
Finally I found time to finish it up. It is pre-alpha quality now, but shows the direction. The only problem is a packaging. I didn’t mean OpenWrt’s IPKG. I am talking about creating a custom build of Dojo to reduce the foot print. Dojo has a special provision for that but so far I was not able to do it getting some strange errors. I hope I’ll get some help from developers.

Migration to new Django admin

19 Oct, 2005 - 1 minutes
I’ve migrated my sites to new Django admin. It is easy to do but make sure that you followed instructions closely. Small mistakes can cost you a lot of head-scratching time. You can find the instructions at the bottom of Backwards-incompatible changes. New refactoring has totally made sense. Meanwhile Robert Wittams & Co is working on new-admin (note the hyphen). Django’s admin is a very nice app (now it is an app!

OpenWrt GUI: it works, kind of

14 Oct, 2005 - 1 minutes
I decided to post some screenshots of OpenWrt GUI running on my browser. I didn’t package it as .ipk yet. Screenshots are hosted on Flickr. If you want to see full-size picture (== undistorted by scaling), go to "different sizes" (it is in "Additional information" on the right side), and select "Large". Please bear in mind that this is the first cut without any niceties. I’ll put some niceties in, but I want to have working functionality first.

OpenWrt: jumpstart with JTAG

9 Oct, 2005 - 2 minutes
As you know I bricked my wireless router. All simple things were tried without any positive effect. Kaloz (of OpenWrt fame) has advised me to try JTAG. It’s a very simple thing: you need a computer, a proper software, and JTAG cable, which can be self-made. Obviously the last part is the crucial one. I made a trip to my friendly neighborhood Altex store and bought all necessary parts: 4 100 Ohm resistors, male & female 14 pin IDC connectors (they didn’t have 12 pin ones, which were modified later using cutters), 25 pin male SUB-D, and 3' 25 pin male to female cable — I figured I’ll make extremely short JTAG "cable" and attach it to short printer cable.

OpenWrt GUI: good, bad news

6 Oct, 2005 - 1 minutes
Today I have good news and bad news. The good news is tonight I was able to work on AJAX OpenWrt GUI a little bit more. It is coming together. I coded my first applet. It shows current stats, nothing fancy. The bad news is I bricked my router apparently by running nvram show repeatedly. I suspect that nvram is corrupted beyond salvation. I have to reset it somehow. I tried simple recipies listed in OpenWrt Wiki but no luck so far.
