Description MIchael Kolmodin 2002-12-03 22:46:06 UTC

Description of problem:
I have configured pppd to call my ISP through a USB-connected serial device. The
connection script works OK. However, if I add the lcp-echo* options in order to
supervise my connection which does not handle DCD/DTR, the connection fails. The
logfile shows that my system only sends lcp-echo-request, nothing else (it
should configure the link)

Version-Release number of selected component (if applicable):ppp-2.4.1-2

How reproducible:

Steps to Reproduce:
1.Create a ppp configuration which calls to my ISP
2.Verify that it works
3.Add lcp-echo-interval and lcp-echo-failure options to pppd (I used a
  configuration under /etc/ppp/peers, but I presume using PPPOPTIONS
  in ifcfg-ppp0 will give the same result)
4 Try to connect, watch failere
5 If not done, add 'debug' option, configure syslog to handle
  messages if not done.
6  Watch /var/log/messages, nothing but lcp-echo-request.

Actual Results:  As above: no connection, just lcp-echo-requests in

Expected Results:  Connection OK, normal connection dialog logged by syslog with
interspersed lcp-echo-requests. Also: PPP link disconnected if physical link
broken despite lack of correct hardware signals (DCD/DSR/DTR) handling.

Additional info:

A typical notebook setup: No fixed serial port, but a USB one on the machine.
Connection through a cellular phone to ISP

Oops, don't know why, but now it works for me. Close the bug, I will reopen it
if it occur again (and I understand why...)
