Unfortunately, my ISP only accepts PAP authentication and as a result of
PPPD's
natural behaviour, I am rendered unable to connect with my USB 3G modem onto
the network.
This patch is supposed to introduce a new configuration option for the
'mobile_ppp'
connection type:
Auth=
It is an array of authentication methods, those prefaced with '!' will
become 'refuse-opt',
and otherwise will become 'require', in the resulting 'options' file.
Something I've patched up that works, cheers!
