Help with automount script

[tris_r]

Greetings all...

I'm a newbie at this so go easy... What I want to achieve is to mount my servers file system when my laptop is able to connect to it via wireless.

This is what I've come up with so far.

#!/bin/bash
#
#Automount network drive

# Check if file system is mounted locally

touch /mnt/mntpoint/dir/connection.up
if [ $? -ne 1 ]
then echo 'Mounted'; exit
else echo 'Ready to mount'
fi

# Check local connectivity to server

/bin/ping -c3 10.14.1.5
if [ $? -ne 0 ]
then echo 'Failed to connect locally'
else sshfs user@10.14.1.5:/home/user /mnt/mntpoint/ -o follow_symlinks
fi

Questions/points

1. If I lose connectivity after mounting and run the script it hangs. Probable when it tries to touch the file that should be there but isn't. Can anyone help with a better way of testing if the filesystem is already mounted?

2. I can't run it as a log in script because the wireless isn't connected at log in. I was going to run as a five minute cron job but was wondering if any one has any idea if I can run it once after the wireless connects. (Kubuntu 9.04 beta)

3. This is just what I've been hashing out and so if anyone can think of a more elegant way to do this please let me know.

4. From here I'm thinking to check if the server is available over the internet if local connectivity fails and possibly sync some files. Anyone with cool ideas for what else I can do lets have them. I'm still learning so projects like this help push me.

Cheers

assuming the server is running *nix, the standard way
to do this is by "nfs mount"

1. on server, add the laptop to /etc/exports

/ laptop(rw,sync,no_subtree_check)

2. on server, add laptop to /etc/hosts

10.14.1.10 laptop

3. on laptop, add a line to /etc/fstab

server:/ /server_filesystem nfs rsize=8192 wsize=8192 timeo=14, intr

4. on laptop, add a line to /etc/hosts

10.14.1.5 server

now if server is running, yr laptop mounts server root
directory "/" on its directory /server_filesystem. If
server is not running, a bootup delay will occur.
