Sending a KILL signal to pppd is NOT a good idea. This signal is not catchable and thus pppd exits abruptly. I hasn't got a chance to do any cleanup, and that might be the cause for your trouble (route flush should not be required if pppd exited cleanly nevertheless). I suggest replacing the "kill -9" by "kill -INT" or "kill -2". The pppd daemon will catch that signal and exit cleanly. _Alain_ -- Alain FAUCONNET Ingenieur systeme - System Manager AP-HP/SIM Public Health 91 bld de l'Hopital 75013 PARIS FRANCE Medical Computing Research Labs Mail: af@biomath.jussieu.fr Tel: (+33) (0)1-40-77-96-19 Fax: (+33) (0)1-45-86-80-68 I've RTFMed.
