I am trying pppd using serial port between an embedded device and a PC.

i had set the /etc/ppp/chap-secrets file with username and password

when i run the command pppd auth i get the below output pppd: The remote system is required to authenticate itself pppd: but I couldn't find any suitable secret (password) for it to use to do so.

what is the command line argument to use for setting the connection using CHAP authentication ?

thanks for the help, Dino

we need to supply require-chap in the argument

require-chap Require the peer to authenticate itself using CHAP [Challenge Handshake Authentication Protocol] authentication.
