# You can download the latest version of this script from:
# https://github.com/MiSTer-devel/CIFS_MiSTer
# Version 2.0.1 - 2019-05-06 - Removed kernel modules downloading, now the script asks to update the MiSTer Linux system when necessary.
# Version 2.0 - 2019-02-05 - Renamed from mount_cifs.sh and umount_cifs.sh to cifs_mount.sh and cifs_umount.sh for having them sequentially listed in alphabetical order.
# Version 1.8 - 2019-02-03 - Added MOUNT_AT_BOOT option: "true" for automounting CIFS shares at boot time; it will create start/kill scripts in /etc/network/if-up.d and /etc/network/if-down.d.
# Version 1.7 - 2019-02-02 - The script temporarily modifies the firewalling rules for querying the CIFS Server name with NetBIOS when needed.
# Version 1.6 - 2019-02-02 - The script tries to download kernel modules (when needed) using SSL certificate verification.
# Version 1.5.1 - 2019-01-19 - Now the script checks if kernel modules are built in, so it's compatible with latest MiSTer Linux distros.
# Version 1.5 - 2019-01-15 - Added WAIT_FOR_SERVER option; set it to "true" in order to wait for the CIFS server to be reachable; useful when using this script at boot time.
# Version 1.4 - 2019-01-07 - Added support for an ini configuration file with the same name as the original script, i.e. mount_cifs.ini; changed LOCAL_DIR="*" behaviour so that, when SINGLE_CIFS_CONNECTION="true", all remote directories are listed and mounted locally; kernel modules moved to /media/fat/linux.
# Version 1.3 - 2019-01-05 - Added an advanced SINGLE_CIFS_CONNECTION option for making a single CIFS connection to the CIFS server, you can leave it set to "true"; implemented LOCAL_DIR="*" for mounting all local directories on the SD root.
# Version 1.2 - 2019-01-04 - Changed the internal field separator from space " " to pipe "|" in order to allow directory names with spaces; made the script verbose with some output.
# Version 1.1.1 - 2019-01-03 - Improved server name resolution speed for multiple mount points; now you can directly use an IP address; added des_generic.ko fscache.ko kernel modules.
# Version 1.1 - 2019-01-03 - Implemented multiple mount points, improved descriptions for user options.
# Version 1.0.1 - 2018-12-22 - Changed some option descriptions, thanks NML32
# Version 1.0 - 2018-12-20 - First commit
#========= USER OPTIONS =========
#You can edit these user options or make an ini file with the same
#name as the script, i.e. mount_cifs.ini, containing the same options.
#Your CIFS Server, i.e. your NAS name or its IP address.
SERVER="retrosmb"
#The share name on the Server.
SHARE="mister"
#The user name, leave blank for guest access.
USERNAME="retronas"
#The user password, irrelevant (leave blank) for guest access.
PASSWORD="retronas"
#Optional user domain, when in doubt leave blank.
DOMAIN=""
#Local directory/directories where the share will be mounted.
#- It can ba a single directory, i.e. "_CIFS", so the remote share, i.e. \\NAS\MiSTer
# will be directly mounted on /media/fat/_CIFS (/media/fat is the root of the SD card).
#- It can be a pipe "|" separated list of directories, i.e. "Amiga|C64|NES|SNES",
# so the share subdirectiories with those names,
# i.e. \\NAS\MiSTer\Amiga, \\NAS\MiSTer\C64, \\NAS\MiSTer\NES and \\NAS\MiSTer\SNES
# will be mounted on local /media/fat/Amiga, /media/fat/C64, /media/fat/NES and /media/fat/SNES.
#- It can be an asterisk "*": when SINGLE_CIFS_CONNECTION="true",
# all the directories in the remote share will be listed and mounted locally,
# except the special ones (i.e. linux and config);
# when SINGLE_CIFS_CONNECTION="false" all the directories in the SD root,
# except the special ones (i.e. linux and config), will be mounted when one
# with a matching name is found on the remote share.
LOCAL_DIR="cifs"
#Optional additional mount options, when in doubt leave blank.
#If you have problems not related to username/password, you can try "vers=2.0" or "vers=3.0".
ADDITIONAL_MOUNT_OPTIONS=""
#"true" in order to wait for the CIFS server to be reachable;
#useful when using this script at boot time.
WAIT_FOR_SERVER="false"
#"true" for automounting CIFS shares at boot time;
#it will create start/kill scripts in /etc/network/if-up.d and /etc/network/if-down.d.
MOUNT_AT_BOOT="true"
#========= ADVANCED OPTIONS =========
