In Mandrake 6.0 I was able to set up kppp without any problems. I then tried Redhat6.1 and tried to set kppp up but it always says the pppd deamon died unexpectedly. I watch the log and it dials ok. I then see the username prompt then the password prompt then a bunch of data characters and immediately the pppd dies. I put the debug option in pppd options and checked the output of /var/log/messages and it said "pppd : The remote system is required to authenticate itself but I couldn't find any secret (password) which would let it use an IP address." Using minicom I can dial the modem and connect. I get the prompt for the username then the password and after that all the data starts coming in. So that tells me it is not PAP or CHAP authentication. I choose script based login from the kppp options (I also tried the others with the same results). I filled in DNS settings. I tried putting "noauth" as a pppd option and after the password prompt it stays up for 30 seconds (kppp says "Logging on to Network") and then dies. 30 seconds is the timeout value for pppd.
I also tried Redhats new RP3 to setup the connection but I get the same result.
It must be a configuration problem but where?
The options file for pppd just has "lock" in it.
I've tried all this logged in as root and as another user.
