LCP terminated by peer

[cerr]

Hi There,

I'm attempting to dial up to the GSM network from Rogers Wireless
(Canada) with a gsm modem from sierra wireless, type GL6100 using pppd.
I wrote a chat script that seems to work well and do the required until
I get the CONNECT message from my apn. I get following messages in
syslog:

Hi There,

I'm trying to dial up to the GSM network from Rogers (Canada).
I gewt the proper AT handshake and stuff going and connected but then there's some LCP messages going back and forth beeforee I'm dropped off the network with a message 'LCP terminated by peer'.
This is from my syslog:

Btw, my modem is a sierra wireless GL6100. please advise what i can do to get my connection up and running properly.

Thank you,
Ron

From the log below, the short answer is that Rogers wants your end to send a
PAP authentication (userid, password), and your end refuses. Without
authentication, Rogers won't let you on to their network, and hangs up on
you.

Fix your pap.secrets file so that it contains the proper authentication, and
make sure that you have authentication enabled on your pppd config.

OK, your system is in communication with rogers

Rogers sends a request for PAP authentication (among other things)

Your setup doesn't think that this is possible

You reject PAP authentication.

And you are gone.

> Why is this? Why do I get disconnected from my peer

because you refused to authenticate, and Rogers wont proceed without
authentication

> and why does it say "LCP terminated by peer"?

because Rogers won't let you continue without authenticating to them via
PAP. Since your side refused authentication, Rogers refuses your connection
and hangs up on you.

> Thank you for any hints or suggestions!

Fix your setup so that it authenticates via PAP with Rogers.

Thanks for that Lew but from Windows I can establish a connection and I
don't have any credentials there either.....

Well, I doubt that. Rogers has given you a username and password which you
have entered /somewhere/ in your Windows system. It may have been part of
the initialization in a "package" from Rogers, or it may have been entered
by hand, but you *do* have it.

And, you *need* it (the username and password) in your Linux pppd
configuration as well. Rogers is clearly asking your system to authenticate
itself using the PAP authentication process, and your system is clearly
refusing to do so.

Find that username and password, and put it in your /etc/ppp/pap-secrets
file. Otherwise, you aren't going to get Rogers to accept your connection.

I promise, I didn't enter any credentials nor is anything preset in the
Windows dial up connection. When I set them in my pppd script in plain text
like:
#noauth
user wapuser1
password wap
(with apn internet.com in the chat script)
I get this:

[Lew Pitcher]

On Thursday 12 July 2012 16:30, in comp.protocols.ppp,

All I can say is that, if Rogers accepted the userid&password, they should
have replied with an AuthAck, which you would see in the log as....

rcvd [PAP AuthAck id=0x1 "welcome message here" ]

But, instead, they replied with

> Jul 12 20:31:35 E10_semiosOffice daemon.debug pppd[1484]: rcvd [LCP
> TermReq id=0x2]

which is unusual (I would have expected them to have sent an AuthNak first)
but not unexpected if they didn't like your authentication.

After receiving (but not explicitly accepting) your login credentials,
Rogers terminates the conversation. At least, now you are sending PAP
credentials.

I can't vouch that they are the /correct/ credentials, nor can I vouch that
there isn't something else wrong. I can only say that this log doesn't
include any evidence pointing to other problems, and (by, in part, the
absence of expected evidence) implicates your PAP credentials.

That's the key information. The peer is asking you to identify yourself
with PAP (simple user name / password), and you're refusing to do so,
probably due to a local configuration problem.

> Btw, my modem is a sierra wireless GL6100. please advise what i can do to get my connection up and running properly.

Assuming you know that you should be using PAP with this provider (seems
likely to me), add this to your pppd configuration:

user yourname

replacing "yourname" with your user name with that provider. Then add a
line like the following to your /etc/ppp/pap-secrets file:

yourname * "your password"

Again, make the appropriate substitutions. The first column is your
user name as expected by that peer. The second column is the name of
that remote system; it's immaterial, so just use "*". The third column
is your password or pass phrase. It should normally be quoted.
