It's 3G connection. It turns to be the chap authentication method problem. As pppd only supports chap ms-v2 and the ISP always initiates as chap md5 algorithm. So, when I set it to be 'refuse-chap' in the option, the modem will try to connect the ISP.
However, now, I met another problem. I got the local IP and remote IP, however, it seems the ISP doesn't response my modem pings or echo. The error messages are: *"No response to 6 echo-requests." "Peer not responding"* Anyone knows why this happens? thanks Xiaohong 2010/11/16 José Queiroz <[email protected]> > Hi Hong Sheng, > > 2010/11/15 hong sheng <[email protected]> > > Hi >> >> I got the following pppd call error for chap authentication in vz system. >> It seems the peer refused to authenticate.
