ifup-ppp nastepna wersja

[Grzegorz Stanislawski]

Witam.

  Podsylam kolejne wydanie mojego skryptu dla initscripts do ppp.
Tak jak juz bylo w poprzedniej wersji, skrypt ma "wsparcie" dla opcji
persist w pppd-2.3.5 i w zwiazku z tym, jak lacze jest zwalone przez jakis
czas to nie wali tak bardzo po logach. Rozwiazany jest problem ifdown ppp
tzn. to chodzi (w oryginalnym skrypcie nie dzialalo to wogole, kilowanie
pppd nie dzialalo, bo ifup ktory ciagle chodzil uruchamial go za chwile
znowu)
 Nowa rzecza jest to, ze plik ze skryptem do chata (chat-ppp?) jest teraz
parsowany przez shell'a zwiazku z czym mozna w nim zamieszczac odwolania
do zmiennych. Wada, mam nadzieje ze nie wielka, takiego rozwiazania jest
koniecznosc escapowania backslashem tych znakow na ktore shell jest
wrazliwy, czyli np &$()|:; i tak dalej.
 W todo do nastepnej wersji na pierwszym miejscu jest opcja demand.

Prosze o pobawienie sie tym skrypcikiem i jesli nie bedzie z nim problemow
(u mnie chodzil ok) o wlaczenie go do nastepnego wydania initscriptsow.

# ifup-ppp script for pppd-2.3.5 (with persist & demand options) ver 0.2
# Grzegorz Stanislawski <stangrze w open.net.pl>
# Features:
#  - since persist option is included to pppd it''s no need to do werid loops
#    ifup-ppp script. This also makes your logfile grow slower when Your link
#    is down.
#  - chat-ppp? file with script for chat is now parsed by shell, so You can
#    include in it shell variables (for example $PHONE, $USERNAME)
#    You can define any variable in ifcfg-ppp? file and use it in chat-ppp?
#    You only have to add it's name into DATAFORCHAT variable
#    Note, that chat-ppp file is now parsed by shell, so you have to escape
#    with "\" all shell special characters like \$;:)(& etc.
