[TriLUG] Road runner dialup while travelling

[Tom Bryan]

My boss has sent me on the road.  At home, I use Road Runner.  RR has recently 
started offering dialup access for those of us who are on the road.  My 
laptop has both Windows 2000 and Linux.  I can connect to Road Runner's dial 
up service from Windows, but I haven't been able to get it working with Linux 
(Red Hat 7.3).  It's been a while since I last did this (with Mindspring), 
but I don't remember having much trouble.

Do I have to set up some sort of ppp0 interface first?  Is that just handled 
automagically?  I include a bunch of information below, but I'm not even 
really sure how to troubleshoot this one.  If anyone can give me some ideas, 
I'd really appreciate it.  

Under the RoadRunner distribution, I found the following script at 
icc/login.scp.

    string prefix = "aolnet/ent."

	"Saturn.BBN"	then DoUUNetLogin
    until 20

    DoANSNetLogin:
	waitfor "login"  until 20
	if $SUCCESS then
	    transmit prefix + $USERID, raw
	    transmit "^M"
	    goto DONE
	endif

    DoUUNetLogin:
	waitfor "login" until 20
	if $SUCCESS then
	    transmit prefix + $USERID, raw
	    transmit "^M"

	    waitfor "Password"
	    transmit $PASSWORD
	    transmit "^M"	
	    goto DONE
	endif


    DoSprintLogin:
	waitfor
	    "Login"	then DoSprintConnect,
	    "Username"	then DoSprintConnect
	until 20

    DoSprintConnect:
	transmit prefix + $USERID, raw
	transmit "^M"

	waitfor "Password"
	transmit $PASSWORD
	transmit "^M"	

	waitfor "Network User"  until 5
	if $SUCCESS then
	    transmit "PPP"
	    transmit "^M"
	endif
	goto DONE

    DONE:
	delay 2

endproc


So, I've tried configuring the dial up account with kppp under KDE 3 on RedHat 
7.3.  When I try to dial out, I can hear the modem dialing and apparently 
negotiating a connection, but it still fails to bring up a ppp interface.  I 
get info like this in /var/log/messages

The exit statuses that KPPP reports from pppd have varied among
       15     The link was terminated because the peer is not responding to 
echo requests.
       16     The link was terminated by the modem hanging up.
       19     We failed to authenticate ourselves to the peer.

At first, I may have had problems because I think the server expects CR/LF for 
line endings.  That might explain the exit status of 15.  I don't think that 
I've seen that again.  CHAP always fails, so I've set the authentication 
method in KPPP to "script based".  I initially didn't have aolnet/net. 
prefixed to my username, so that might explain some of the 19 exit statuses.  
CHAP still fails, but the script based authentication consistently gives me 
that last tyle of message.  I'm guessing that ppp0 isn't actually coming up 
and that KPPP is timing out and hanging up.  Of course, I'm not even sure 
about that.  Any ideas how to troubleshoot this sort of problem and be sure 
that you're making progress?  Anyone got this working already?
