Package: pppoe
Version: 3.5-4
Followup-For: Bug #298582
I have found a bug in pppd that may explain why this happens.
pppoe-server invokes "pppd pty 'pppoe ...'" with no file descriptors open.
pppd does an openlog() and gets /dev/log on fd 0 (you can already see where
this is going).
Later, when pppd is setting up file descriptors for the pty subprocess, it
puts the pty master on fd 0 and 1 and the logfd (which is a distinct log
file, in addition to syslog, normally set to /dev/null by now) on fd 2. It
handles this all very carefully, avoiding several potential problems with fds
getting stomped on. Then it does a closelog(), which stomps on fd 0.
pppoe now gets invoked with fd 0 closed, and hilarity ensues.
Moving the closelog() up a few lines in pppd fixes it for me.
