# Pre-removal script for the Samba package for Debian GNU/Linux.
#
# Written by Eloy A. Paris for the Debian project.
#
DEBIAN_CONFIG=/etc/samba/debian_config
NMBDPID=/var/state/samba/nmbd.pid
SMBDPID=/var/state/samba/smbd.pid
# The most important thing the prerm script must do is to stop the Samba
# daemons (nmbd and smbd). Note that this can be tricky since Samba
# can be running from the inetd meta-daemon or as daemons (it's a
# user choice).
# Before we stop Samba we need to know how it is running (from inetd
# or as daemons). We could source in the debian_config file but it
# is safer to grep /etc/inetd.conf.
if grep -q '^netbios-ns' /etc/inetd.conf; then
# Samba is running from inetd. We need to disable the Samba daemons
# in /etc/inetd.conf before we stop the daemons. Otherwise traffic
# in the NetBIOS ports will make inetd start them again.
#
# Note: user preferences regarding the mode he/she wants Samba to
# be run (inetd or daemons) will be lost next. In the postinst
# we depend on the information present in the debian_config
# file to restore everything back to the way it was.
update-inetd --disable netbios-ssn
update-inetd --disable netbios-ns
# Now it is safe to stop the daemons...
# I have just recalled that old versions of nmbd and smbd did not store
# their PID's in /var/samba/state/ (or whatever directory
# was used for this purpose in configure), so I can't use
# --pidfile in start-stop-daemon to stop nmbd or smbd. I
# will handle this by testing first whether the PID file exists.

# nmbd must be dead by now, now it's smbd's turn

# Samba is running as daemons. No problem here, just stop Samba...
