Subject: PPP et automount >> mount: RPC: Timed out
Bonjour a tous,

Je suis confronte a un probleme vraissemblablement lie a PPP et automount.

En effet, deux appareils sous linux 2.4.18_mvl30 (montavista linux embarque)
relies par une liaison point a point.
Sur l'appareil que je nommerai "Master" car il etablit lui meme la connexion PPP
entre les deux, j'effectue une premiere fois l'automountage par la commande cd
(cd /acterna/user/slavedisk), pas de probleme. Je quitte ensuite (cd) j'attends
plusieurs secondes (je ne casse pas la liaison ppp), et je retente un cd (cd
/acterna/user/slavedisk) pour un nouveau automountage et la probleme ">> mount:
RPC: Timed out"

Plus de details sur la manip.
