Dear pdaXrom development team,
I had hard time trying to make
OpenVPN work on my C860 with pdaXrom installed. 1.0.5 wasn't configured to include tun/tap module, so I tried to build it myself from original kernel source for C860.
This was probably not the right thing to do since module didn't seem to work after tunnel is established, moreover kernel keeps crashing when tun device is closed. Could be as simple as certain kernel interfaces has been changed for good in pdaXrom build and are not binary compatible with something build out of original kernel sources.
Would it be possible to include tun.o in kernel configuration for opcoming release ?
Or maybe someone would share some experience on how to build pdaXrom kernel tree? I knew the sources are at
http://www.tomsk400.com/pdaXrom, but the procedure itslef is not very clear.
Thanks a lot
