Olivier:
I am not familiar enough with how ping (ping.c?)
implements the "-I ppp0" feature, much less how
to code it in perl. I thought the bind() feature
would automagically help the kernel decide which
interface to stick it on, but I guess that does
not work either. Sorry, but I have no ideas.
Maybe the perl porters know someone smart enough
to understand this network issue enough to port
that C code feature from ping.c to perl?
