Binary package hint: ppp

When the ppp daemon establishes a connection, the /etc/ppp/ip-up.d/0000usepeerdns file is executed.

Where the pppd "usepeerdns" config options is used (most cases), the 0000usepeerdns script tests for the nscd (name service cache daemon) being running incorrectly [1], so does not restart it.

The correct pid file to test for is /var/run/nscd/nscd.pid. Rather than restarting the service and flushing everything, it is better to invalidate just the hosts [2].

Diff against original file is in [3]. Apply with 'patch -l'.

  /etc/init.d/nscd restart || true
fi

[ -e /var/run/nscd/nscd.pid ] && nscd -i hosts
