Hi,

if the peer you are trying to connect to requires authentication (like in
all ISP servers) then you would have to take care of populating the
/etc/ppp/pap-secrets or /etc/ppp/chap-secrets which would have the
username and password required for authenticating into the peer. If the
peer doesn't provide the ip adress for either ends, that would also have =
to
be added to your list of options.
