QNX is a pppd server with authentication enabled

QNX Newsgroups (Archives) qdn.public.qnx4

Hi all,

I have a PPP connection between a QNX 4.25E + TCP/IP 5.0 and Win2k

QNX is the server, Win2k is the client. On the Win2k side I am using a
direct cable connection with the proper setting of the properties.

The link is working correctly when authentication is disabled:
pppd localPPPHost:remotePPPHost debug passive /dev/ser1

When I enable authentication with:
pppd +pap name myName localPPPHost:remotePPPHost debug passive /dev/ser1

and I provide the /etc/ppp/pap-secrets:

/etc/ppp/pap-secrets

  •      myName          ciao

pppd terminates immediately with the message:

Apr 27 20:33:40 localhost pppd[1949]: peer authentication required but
no suitable secret(s) found
Apr 27 20:33:40 localhost pppd[1949]: for authenticating peer
pppRemoteHost to us (myName)

I tried to change the way in which I specify the local host, and its
reference in the secret file, without any effect. Where was I wrong ?

=================

I did also another test, I enabled +pap and login:
pppd login +pap localPPPHost:remotePPPHost debug passive /dev/ser1

The user:password pair from Win2k matched a valid pair in QNX passwd,
and I enabled pap on Win2k as well.

In this case pppd did not stop, but the procedure failed. Here is what I
extracted from syslog:
