pppd call problem

Hello, i have a problem with pppd, i try to connect the RAS Server Win
2003) of my factory network, but the pppd disconnect me after the
authentication. The syslog is the following, i use chap and i change
the init string of the modem and the syslog is the following (i change
in log USERNAME and PASSWORD (i think) -)

Can you said me what is the meaning of LCP terminated by peer

In the log pppd accepts EAP (Extensible Authentication Protocol) whose
configuration file is /etc/ppp/srp-secrets. The format is the same
as for pap-secrets and chap-secrets but while EAP supports CHAP it is
not CHAP and the username and secret is expected to be in srp-secrets.
man srp-secrets.

If you want CHAP then you can try refusing EAP by adding the pppd option
refuse-eap . However, since the peer gets to specify the authentication
it may not work.

I'm not sure what your comment means. There is no sign in the log that
a password was sent and TermReq is an LCP terminate request. My _guess_
is that the RAS side doesn't like your username (or password if sent)
and so terminated LCP. That could be the case if srp-secrets isn't
configured correctly..

I can't say what the (...) means. Usually control characters in a log
mean the original characters had hex representations beyond 7f and the
high bit was stripped in the process of generating ascii text. But the
() enclosing something with a "." at the end does look a lot like a
comment of some sort.
