Bash Script to Mount NAS - BASH Help Required!

Hello all.

Instead of having to do ...

Code:

sudo mount -t cifs //x.x.x.x/public  NetworkFolder

...every time I boot , I wanted to create a bash script which I can double click to run.

So I created a file , thusly .

Code:

#!/bin/bash
sudo mount -t cifs //x,x,x,x/public NetworkFolder
echo "Network Drive Connected"

I saved this a NetConnect.sh and did a

Code:

chmod +x NetConnect.sh

NOW

If I double click the file in Thunar, it doesn't work

I discovered why, when I opened a terminal and did this

Code:

bash NetConnect.sh

Because I have to sudo to use mount, the bash script asks for a password when run from the terminal. I am guessing that when I double click to run, the lack of password causes a fail.


Does anyone know a work-around to this ? Can I pass the password to sudo somehow in the bash script ?

As you can see, I've made a fair bit of headway through google and these forums, but the last bit is evading me.

Please help!

Thanks in advance.

Mark.

 

A few different ways.
If you want to run each time it boots, put the commands (without sudo) in /etc/rc.local.

Otherwise, add a line to /etc/sudoers. Are you running this on Linpus? Usually it doesn't need a password.
However, assuming the user name is user, add this to the END of /etc/sudoers. (With sudo, last command wins, so if you have something like wheel group can do everything, and add a no password thing above it, it won't work--it processes in order, so that the order is important.

Check where mount is--it's probably bin.

Do
which mount
You should get back /bin/mount
If it comes back with something else, like /usr/bin/mount, use that.
Anway, at the end of sudoers
user ALL= NOPASSWD: /bin/mount

 

scuzzphut,

Consider using SUID. Read about it here ...

http://www.newlinuxuser.com/explain-wha ... nd-setgid/

Then you shouldn't need to use "sudo" within the script.

As to running it in rc.local, I doubt it would work as network connections are made way later in the process.

Cheers.

 

That's odd--Linpus runs rc.local before the network?

Fedora runs rc.local after everything else, however, if what you say is the case for the OP's situation, then, OP, forget that suggestion of mine.

 

This is because Linpus doesn't really use the standard SysV init system (most of the services starts after login. To to OP: the correct place to put it in is /etc/rc.d/slim/nowait.sh after the line that starts the network.

 

thanks for the info and suggestions, guys - I'll report back once I get it working

 

ok - SUID didn't seem to work.

I removed sudo from the "sudo mount..." line and did the chmod to set the SUID on my script.
Unfortunately, running the script returns a "mount.... only su can do that" type message.

So I added sudo back into the script and it still asked me for a password when I ran it, eve with the SUID set.



So... on to option 2

 

Just curious, after you did the chmod to set the SUID bit, was the script owned by root? One way I can think of doing this is to turn the terminal over to root, by: sudo su -
and then running chmod on the file.

You'll probably have success autostarting the commandline itself in nowait.sh after it has started the networking.

Cheers.

 

No joy with either, unfortunately

No matter what I do with the shell script, sudo wants a password when run.


As for putting the line in nowait.sh - this works when I'm connected via ethernet, but not wi-fi. I realise that this is because the wifi connection isn't started until the UI is up, so not much I can do.

It would just be nice to have an icon I could click to connect me to my NAS :cry:

Will keep pluggin away = any more ideas gratefully received and thanks so much to you guys who have pitched in so far.

 

Well, you could create a .desktop file which contains your exec= command, I'd think. If you want it on your Linpus desktop, you'll need to assign some sort of icon to it. You can use an existing .desktop file to get an idea how to write a new one for your command.

Cheers.

 

OK, I forgot about wireless networking. Try putting the command at the end of /etc/sysconfig/networking-scripts/ifup-wireless

 

Hi,

I use a bash script (called mountdirectory):

#!/bin/bash
mount -t cifs //ipaddressofshare/directorytobeshared /mnt/directory -ousername=yourusername,password=yourpassword

Note the -o before username, it has to be there.

I have to be root to use it, so, in terminal I get to be root with:

su -

then type my password

You could use sudo, but what the heck: if your are to be root, let it be root all the way! But be careful, root means you are God! So make no mistake...

I am quite sure that calling this script from rc.local should work, because rc.local work as root.

Don't forget to make your script executable with CHMOD 755

Have fun,

Pierre Forget
