Nuno: I apologise if the following explanation means nothing to you. It
may however be useful information to other developers.
I believe that the cause of this bug was that the daemonize() function
closed standard file descriptors rather than replacing them
with /dev/null. This meant that when start_pppd() opened its pseudo-pty
it was given a file descriptor number of 0, 1 or 2, which it closed
before attempting to dup2() it to the correct file descriptor. The
dup2() call failed, but this was not checked. It then started pppd with
file descriptor 0 (stdin) closed, hence the error message.
This was not fixed in version 0.69 but is fixed in the current version;
based on the changelog I believe it to have been fixed in the above
version.
Ben.
