I have wvdial working from the command line in a debian squeeze 32 bit install.
Googling around revealed several suggestions to simply use
auto ppp0 iface ppp0 inet wvdial
However, upon reboot I get the error:
startpar: service(s) returned failure: wvdial ... failed!
I have also had zero luck getting wvdial to run from an init.d script. Any suggestions?
