Protecting a USB input with a password?

Hi-
I'm setting up some new intel MiniMacs for my students. I'd like to be able to use USB flash drives, iPods, etc on their computers, but dont want them to use this sort of stuff without my permission.
How can I get Tiger to prompt the user for a password once something is inserted in a USB input?
Thanks

I haven't had a chance to test these things in "Tiger", but in "Panther", it was possible to load / unload the kernel extension for USB mass storage drivers pretty much at will. This won't block people with original firewire iPods, but might have been ok for the newer USB ones:<pre>sudo kextunload -b com.apple.iokit.IOUSBMassStorageClass</pre>Also, the 'mount-controls' settings of 'mcx_settings' in the "NetInfo' database did sort of work in "Panther" - the limitation was that restricted users wouldn't be able to log in after a non-restricted user had logged in since the time the machine was booted. As long as only restricted users logged in after booting, everything continued to work, and all external drives would either be prevented from mounting, or would require a password at the time they were connected. Having to reboot after a non-restricted user logs in, just to restore the ability of restricted users to log in, will probably make it impractical, but the option is there (provided it works in "Tiger"), and might be ok for a student only machine...

How do i lock a specific firefox profile with a password?

I have 3 profiles in firefox (using firefox profile manager) .I want to lock access to only my profile with a specific password and keep others unlocked.(like childlock in google chrome)

You can't do that reliably in Firefox.
If you would use an extension then holding down the Shift key to start in Safe Mode is sufficient to bypass the password.
Best is to use a separate Windows user or guest account and protect your Windows account with a password.

How can I set up SMB file sharing to share my PC external hard drive on my Mac with no password protection?

I am having the worst trouble with two things. I am very aware how to get the server to show up via SMB, but every time I log off the Macbook, the server's disappear. OK, so I went into "System Preferences" and hit "Users and Accounts" and added the server as a log in item. Worked well, except how do I stop that password prompt from coming up? I am using a Guest account with no password but I continue to get the password prompt. There is nowhere to hit remember password or anything. I have the option to remember the password in the keychain but I have no way of preventing the pop up.
Another issue I'm having is I have a Canon Pixma MP620 printer connected to my PC through USB. Three other PC's can connect wirelessly to print through the home network. My Mac does not find the printer, and when I manually add it, it recognizes it but WILL NOT print. It comes up with error messages like Authentican Required and connection issues between printers.
I have no password protection on my PC and have enabled sharing of all devices and folders through the Homegroup on the PC. I just can't figure it out. I am new to Mac and would love to get these two things figured out.
Thanks in advance for reading!

Hi Bengt, Thanks for your input, much appreciated.
I have a WD 1TIG hard drive and are using usb connection, is it possible to use fire wire with these? I have had trouble with a lot of the videos I Imported, once they downloaded the file in the viewer window showed up blank and when I mouse over them it places a picture of another file in the window and wont drag and drop into the movie window, like their corrupted or something? Had to delete just about all of them and start again. Also is it possible to select a bunch of videos in the viewer window as to change the dates to the correct dates? All I have been able to do is "select all" which is no help.

I am reading on this site about the error I am getting and it wants me to change some files that I am not comfortable messing with. Mainly because it is like a foreign language. Will the store do this for me or tell me if it is neccessary?

And why is it suddenly in english ? I startet from a german installation. How can i protect one E-Mail account with a password may be the office part and give

may be in the office with a password, and give the other free for the rest of the users without password, the master password didn't help here I mean, or the handling for this is not clear to see for me

There is no full or partial password protection that is really more than an inconvenience.
You could however use the operating system permissions, but again whole application would be the result.
I have heard of updates occasionally reverting to English, an install will set it back. http://www.mozilla.org/en-US/thunderbird/all.html as data and program are separate reinstalling will not be an issue.

How to protect against a pdf printing without protecting the file with a password ?

I want to know if it's possible to protect a PDF against printing without protecting the file with a password ?
It's possible to make it with Acrobat Reader or another version ?
Thank You
Best regards.

Hi,
Yes, you can restrict editing and printing of the document; although you have setup a permission password (To restrict the users from changing the document permissions).
Please follow the steps mentioned below:-
Open the file in Adobe Acrobat- Document properties- Security- Change security method to password security- Select Restrict editing and printing of the document

Car with USB input - but music plays from phone sp...

Hi all,
Last week I got a new Nokia Lumia 520. I've had iPhones for years, but since getting an iPad, though I'd have a change of phone.
Our Nissan Quasquai has a usb input which connects straigh to the head unit. I can plug my iPad straight into that usb port and it plays music through the car speakers, with the added bonus of being able to change tracks on the steering wheel.
However, an iPad is a chunky beast and when family are in the car its not practicle. So I thought I'd put some music on my Nokia and see if the same functionality is available. Unfortunatly when I connect it to the car through the usb stick, it plays from the phone speaker, not the car speakers.
Is there a setting I need to change within the phone, or is what I want to do just not possible? My next option is to play with a usb memory stick.
Many thanks is advance for any help and guidence.

there isnt a setting that will allow that to happen.
the phone cannot play audio/video through the usb. it is for data transfer and charging only.
your cars radio integrates and controls your iStuff because it has the software integrated to allow for it.
if you have bluetooth, just connect your device to your car through bluetooth and play it that way.
my pioneer still allows me to pause, play, fwd, etc on my nokia that way. i just cannot go through the menu system.

Protecting Folders with a Password

Is it possible to protect a folder with a password?
I want to create a sensitive document in OmniOutline. This program does not offer password protection for the files it creates. So I would like to make the folder the file will be in password protected. I don't want to go through the trouble of creating a new user account on the computer, just for this one file.

Protect PDF files with a password

Hi everyone,
Do you know if there's a way to protect PDF documents with a password? I don't mean those apps (e.g. Google Reader) that let you password-protect your files just while you're using/viewing them on the iPad, I'd like an app that if you want (let's say) send your protected PDF via mail, it's still protected!

I finally managed to find the application I was looking for: it's called Foxit PDF nad it's free to download on the App Store!

Password protect a USB printer?

I'm trying to figure out how to password protect a USB laser printer that is shared between two 10.4.x G5s. I don't mind altering the cupsd.conf file, I just need some clear directions. I looked at the CUPS documentation online, but found it a little less "user-friendly" than I'd like.
What I want to accomplish is that a password is required to print from either Mac, and, if possible, that the password is different than the user's login. I'd also welcome the recommendation of any third-party software that can do this.
Thanks.

The first flash drive I ever bought was a Lexar 128mb and there was software that came installed on it to allow for password locking of the drive.
They don't have it for download anymore, and it didn't work for anything but a Lexar drive anyway.
There are several companies that make "universal" security programs for flash drives both Win and Mac.
Google "Password Protection for flash drives" and you'll be treated to a host of results. Your best bet may be here: http://www.rohos.com/free-encryption/

Protecting a webpage with a Password

I need to protect a page on our website with a password.
I realise this can only be done server-side and our website
is written in
Dreamweaver using HTML code.
I thought I had solved the problem when I found a really
good, free php
script (I don't know anything about PHP) but if I understand
the
instructions the whole website would have to be written in
php for it to
work, so it's no good.
The company who host our website do not offer any of their
own scripts for
such a purpose but have no objection to us uploading a script
of our own.
Can anyone give me advice or refer me to a website that will
help me achieve
a password protected web page?
Your help will be appreciated.
Noel

Thanks very much John,
I called RM and it seems likely that they will be able to
create a password
protected directory on their server.

Locking one partition with a password or protecting it otherwise

I have an internal HD that is partitioned. Would it be possible to lock one partition with a password or protect it from prying eyes when I let a 'stranger' use my computer? I know I could put a folder on it with TrueCrypt, but since I would only want to occasionally lock the disk, it is not really an option.
Love to hear.

Thnaks Király
Use Finder -> Get Info on the drive to change the permissions on your partition. Set your user account to be the owner, and then set Group and Others to No Access. Then let guests use any other user account than your own.
Good one had not thought of that. Is however as Thomas said not a optimal solution as there are ways around it.
Is there a way to make the disk invisible and not accessible? Or have it not mount for certain users?

Hi wonderingtoday,
Yes, you can! If you have Acrobat, you can assign an "Open Password" to the PDF, so that only people who have that password can open the PDF. If you don't have Acrobat, you can try it for free for 30 days. For more information, see www.adobe.com/products/acrobat.html.
