OMAP3 Card Formatter License

Filed under: Uncategorized — XorA @ 3:04 pm

There is an updated and bugfixed version of this script now added to the OE git repository where all updates from now will be done.
Latest Version

At a request from TI developers I have decided to change the license of the script to GPLv2 as its more important to me that people can use the the script than spend their time arguing legal points.

Improved OMAP3 Card Formatter

Filed under: Geek, Work — XorA @ 6:40 pm

There is an updated and bugfixed version of this script now added to the OE git repository where all updates from now will be done.
Latest Version

Got some feedback from people on IRC so added some checks so people with builtin card readers can run the script without having to edit it.

OpenVPN Hiding in HTTPS

Filed under: Geek, Work — XorA @ 5:33 pm

So it took me a little while to gather the right set of docs to get this working but I find it useful when in places where you can get http/https connections but nothing else.

This is using tun network interface so make sure that is available on your server.

I also created a dummy0 with a random ip 192.168.123.1 so I could connect to services on my server without bypassing the VPN tunnel. The dns server running on 192.168.123.1 redirects server.external to that ip address.

Anyway here is my server config.

Download 




As you can see OpenVPN binds to the external port 443 and forwards non VPN traffic to localhost:443 where the webserver is listening.
