[Voyage-linux] Re: Network problems voyage 0.6.2: ifup is a known problem not voyage specific

[(spam-protected)]

Apparently the 'ifup' problem number 3 below is a known problem of the
ifupdown program:

"It is currently not possible to use ifupdown to perform auxiliary
configuration of PPP interfaces. Because pon exits before pppd has
finished making the connection, ifup runs up scripts before the PPP
interface is ready for use. Until this bug [ 58] is fixed it remains
necessary to do auxiliary configuration in /etc/ppp/ip-up or
/etc/ppp/ip-up.d/. "
