CoovaChilli Captive Portal on WRT54GL

This page discusses how to use CoovaChilli (openwrt-54g-squashfs.bin) with a WRT54GL as a captive portal.  It took me several times to get this to work.  During my attempts, I somehow messed up my configuration.  tried to upload a new firmware and start over, and it turns out that CoovaAP takes over the firmware, and won't let you install anything else.  SO USE COOVAAP AT YOUR OWN RISK.  The only way I was able to reflash the router was with the JTAG cable again.   This thing has been worth its weight in gold with this router, as it's helped me recover from a corrupt BIOS (CFE Image), enabled me to reflash the router when the boot-wait was not turned on, enabled me to reflash nvram that was corrupt and I couldn't fix (say with the reset button), but mostly just fix bad firmware images that like to take over the OS and lot let it go.  

Uploaded the CoovaAP WRT54GL 1.0-beta.8 openwrt-54g-squashfs.bin file to the router, and started over.   Tried to do this directly via the JTAG cable, which took over three hours, but it didn't work.   So I uploaded the original Linksys firmware, and upgraded through the GUI.  

When CoovaAP booted, I changed the default password, and then went to the Hotspot section.  Under the "Configuration Tab", I changed the Hotspot type to Internal, Wireless only, Deny, Http for configured users.  

Under the "Access List" tab, I added one guest.  

Under the Portal Tab, I selected "Login Page", and changed the HTML to what I wanted it to say.  The cool thing about this is that it allows you to customize your login page!  

I applied changes, and tested it.  It didn't work.  So I went in to the GUI and started CoovaChilli (it was installed, but not running).   This worked like a champ (after unplugging and then plugging the router back in).   

I uploaded an image for my splash screen, to test if I can modify the redirect page.  This was done by scp'ing it up with the command: 
#scp beboNoBorder.jpg root@192.168.1.1:/jffs/usr/bebo.jpg  

I tried several times to get CoovaChilli to see this image, but it wouldn't until I put it in the /etc/chilli/www/ directory.  So apparently any files that you want CoovaChilli to display have to be here.   

I then changed went to Hotspot/Portal and selected Header from the drop-down, and edited it to read: 



    ALT="Bebo HotSpot"
    TITLE="Bebo Hotspot"

A couple of items worth note is that the Coova firmware is a little buggy, and wouldn't finish applying the changes I made unless it had an Internet connection.  Also, a user has to have a browser with JavaScript enabled to see the login page.   This is a little ghetto, but I suppose that most folks have Javascript enabled on their browsers anyway, so I guess that I can live with it. 

So I have an authenticated, encrypted Captive Portal to the Internet.   Finally!   Here is a screenshot of what the portal page looks like:

2025 Tap And Map

 Tap And Map is back with new and improved installation instructions!   Here is an old video showing what TapAndMap is, for those who may not know: https://www.youtube.com/watch?v=gRfQzBjrhEE you'll notice that it's been a while since I've touched Tap And Map.   Because it's been so long since I built this, the old installation instructions would NEVER work to build it today (Feb 2025).   Plus, there was a Google Maps API bug that has troubled me all this time, as Google Maps would decide not to reload the page and I'd have to clear my history (lame).  Because my old code was built as an all-in-one method, so packets were sniffed, looked up, displayed, and logged, all in one large monolithic module, there was no easy means to troubleshoot.    So I've now decided to Sniff packets, lookup their IP information, and store the data in one script, and read that file, parse and publish html files in a separate module.  That allowed me to b...

HP c6180 Printer and Vista

Hp c6180 driver issues with Vista Home Premium My wife has a Vista Home Premium laptop, and the HP C6180 Photosmart printer keeps disappearing from her available printers.  The only way I've found to fix the problem is to reinstall all the HP software. When I do this, I have to download the (large..507M software from HP, or reinstall the printer (ONLY the printer, not the scanner) with the installation disk, as the drivers are not discovered with a "Windows Update" setting.  My guess is that is because HP doesn't like people to install only the printer driver, which would be easy, but they want folks to install all their crapware as well, so they are withholding the drivers from the on-line Microsoft printer database.  So keep your installation CD!  I've also found that unless I install everything on the CD or in the Full Version download (HP Customer Participation Program, HP Imaging Device functions, HP OCR SW, HP All-In-one SW, HP Photosm...

atftpd vs tftpd-hpa

Recently I was trying to tftp files from a Windows computer to a Kali box.   One version of Windows worked, but another didn't.    After much troubleshooting, here were my symptoms: I could tftp a file from-to any Kali box from-to another Kali box I could NOT tftp files to a specific Windows 7 box from any Kali box I could NOT tftp files to a Chrooted-Ubuntu-Chromebook box from a Kali box After MUCH troubleshooting, going through every setting in atftpd, it seemed like it literally was a client OS problem.  Different clients simply would not download files---unacceptable. Thus, I switched to tftpd-hpa.   To install: apt-get install tftpd-hpa files go to/come from /srv/tftp, but it needs to be a tftp user. Thus, I needed to: chroot -R /srv/tftp Also, if you want to be able to put files ON the tftp server (from a client), you need to modify /etc/default/tftpd-hpa: change "TFTP_OPTIONS="--secure"  to "TFTP_OPTIONS="--secure --create" ...
