Here’s a quick and easy way to get Windows shares up and running in your Debian server:

#! /bin/sh
### BEGIN INIT INFO
# Provides:          cifs-share-x
# Required-Start:    $local_fs $network $named $time $syslog
# Required-Stop:     $local_fs $network $named $time $syslog
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Description:       Automatically mount Windows shares in Debian Linux
### END INIT INFO

#
#   To install this, run as root:
#   export SERVICE_NAME="cifs-share-x"; curl "https://gist.githubusercontent.com/caHarkness/22bb218d016663444b1a64023937530d/raw/cifs-share" > /etc/init.d/$SERVICE_NAME; chmod +x /etc/init.d/$SERVICE_NAME; sed -n "s/cifs-share-x/$SERVICE_NAME/gp" /etc/init.d/$SERVICE_NAME; ln -s /etc/init.d/$SERVICE_NAME /etc/rc2.d/S99$SERVICE_NAME; nano /etc/init.d/$SERVICE_NAME; sleep 1; systemctl daemon-reload

This /etc/init.d script is available on my GitHub as a gist, you can see the most up-to-date version of it here. To make things even easier, you can run the following, single-liner to install this automatically:

export SERVICE_NAME="cifs-share-x"; curl "https://gist.githubusercontent.com/caHarkness/22bb218d016663444b1a64023937530d/raw/cifs-share" > /etc/init.d/$SERVICE_NAME; chmod +x /etc/init.d/$SERVICE_NAME; sed -n "s/cifs-share-x/$SERVICE_NAME/gp" /etc/init.d/$SERVICE_NAME; ln -s /etc/init.d/$SERVICE_NAME /etc/rc2.d/S99$SERVICE_NAME; nano /etc/init.d/$SERVICE_NAME; sleep 1; systemctl daemon-reload

(remember that this line may change, refer to the comment in the gist)

Doing so will download the most current version of the script, save it as cifs-share-x by default, and open it for editing in nano automatically. Be sure to configure the script correctly! Upon saving, systemctl daemon-reload is made aware of the new script. You can call service cifs-share-x start to start the service, or just reboot instead. If you want to do this for multiple Windows shares, just change cifs-share-x in the export SERVICE_NAME= statement and repeat the process!

This service will manage the mounting and unmounting of the share located at //DESKTOP-NAME/Share (forward slashes are used in Linux) to the /mnt/Share directory in Linux, and allowing for easy directory listing, editing the service script, and uninstalling it altogether!
