You are receiving your own replies. A very common reason for this is that you forgot and sent a carriage return to the far side before you started ppp. You do not show us the prior negotiations-- ie the output from chat-- top see what you sent. If you are using chat, terminate the last chat string with \d\c Ie, a one second pause and do not send a carriage return. Of course you might have miswired your serial cable and wired the output to the input. but that is unlkely unless you wired your own cable. It could also be that your modem is echoing back everthing. > <31>Jan 1 00:53:18 pppd[40]: sent [LCP ConfReq id=0xa <asyncmap 0x0> <auth > pap> > <31>Jan 1 00:53:18 pppd[40]: rcvd [LCP ConfReq id=0xa <asyncmap 0x0> <auth > pap> > ... > <29>Jan 1 00:53:18 pppd[40]: Serial line is looped back. > ... > the pppd server runs well. and the scripts runs well on my redhat9.0. > this problem seems to be resolved by adding a option ,-mn,but the -mn? Option to what?
-mn is a option in option.tpl, in the ppp-HOWTO
