Hello guys, Trying to set up a ppp server and facing the following error message when calling the system: Dec 1 18:28:11 localhost PAM_pwdb[18424]: (login) session opened for user pppu by (uid=0) Dec 1 18:28:11 localhost modprobe: can't locate module char-major-108 Dec 1 18:28:11 localhost pppd[18425]: The remote system is required to authenticate itself but I Dec 1 18:28:11 localhost pppd[18425]: couldn't find any suitable secret (password) for it to use to do so. The parameters are: Server side: chap-secrets: empty options asyncmap a000 passive crtscts modem debug lock options.ttyS0 (the modem is linked to such tty) 192.168.250.1:192.168.3.2 115200 pap-secrets: empty ~/pppu/.ppprc -detach silent /usr/sbin/pppd access right: -rwsr-xr-x Client side connect Where the pap.chat is debug crtscts modem ipcp-accept-local ipcp-accept-remote lock defaultroute I have really no idea about what means: can't locate module char-major-108 Authentication as not requested by server.
