Mod: helper script for network shares

[Drutt]

I have knocked up a script that attempts to simplify nfs / smb setup by allowing shares to be configured on the box, using folder names in a special "settings" directory to add and configure shares. It runs in the background, pinging the host(s) and mounting / unmounting the share when applicable. This should solve the problem of the Humax locking up if the computer goes to sleep. Its a bit rough and ready at the moment, and only tested on an HD. I'd appreciate any feedback / improvements / HDR testing, and then I can put it into a nice package

Put the script in a file called /mod/sbin/scanMounts, and create a startup script in /mod/etc/init.d to kick it off (with an "&" after to run in the background). When a new directory is created in smb or nfs, after a few seconds it should create template "options" within it for you to fill in.

#!/bin/sh

TryMount()
{
    type=$1
    name=$2

    host=$(ls "$name" | grep -e "^host" | cut -d'=' -f2 | sed -e 's/_/./g') #convert "_"s to "."s in host
    folder=$(ls "$name" | grep -e "^folder" | cut -d'=' -f2 | sed -e 's/_/\//g') #convert "_"s to "/"s in folder name

    ping -c 3 $host > /dev/null
    if [ $? != 0 ]; then                # mount or unmount?
        echo "$host not found.."
        # unmount if mounted
        if [ -d "/media/$name" ]; then
            echo "umount "/TEMP/$name""
            umount "/media/$name" -l
            rmdir "/media/$name"
        fi
    else
        if [ ! -d "/media/$name" ]; then
            echo "$host is on-line - attempting to mount"
            mkdir "/media/$name"        # and in My Videos?
            if [ $type = "smb" ]; then
                user=$(ls "$name" | grep -e "^user")        # keep the [user|password etc]=... for these as they go into mount int that format
                password=$(ls "$name" | grep -e "^password")
                domain=$(ls "$name" | grep -e "^domain")
                echo "mount -t cifs "//$host/$folder" "/media/$name" -o $user,$password,$domain,$workgroup"
                mount -t cifs "//$host/$folder" "/media/$name" -o $user,$password,$domain,$workgroup
            elif [ $type = "nfs" ]; then
                echo "mount -o soft "$host:/$folder" "/media/$name""
                mount -o soft "$host:/$folder" "/media/$name"
            fi

            if [ $? != 0 ]; then                # failed

This looks very usefull! I'll have a go at this tonight on my HDR if I have time. Thanks.

Well done Steve.

Just need this integrated into the webif and do it all graphically - tongue in cheek, but great work none-the-less.

Haven't got round to this yet, but thinking it ought to be something I do.
