Questions[dialog](server)

So, in order to prevent console-UI (newt, snack, dialog) prompts during the dpkg post-install, you have to do something like:

debconf-set-selections <<< 'mysql-server mysql-server/root_password password password'
debconf-set-selections <<< 'mysql-server mysql-server/root_password_again password verify_password'
apt-get -y install mysql-server

• Is there a rule for this?
• How do we discover the prompt names/descriptors for other packages that invoke the console UI in order to prevent them?
• Would we likely have to dig through the source-code to figure out how the prompts are invoked?
• Is there a simple way to just choose all defaults (effectively clicking on whatever the default button would be and/or taking the correct text/options)?

Thanks.

NOTE

It looks like setting this variable is the solution for taking the defaults:

DEBIAN_FRONTEND=noninteractive

I am creating a menu to append or overwrite ssh keys for multiple users using dialog --checklist. The menu is something like this

    0) append
    1) user1
    2) root

What I would like to happen is if option zero is selected and either option 1 or 2 or both are selected it would append rather than over writing the ssh keys when it regenerates.

I'm new to dialog and can't seem to come up with the logic needed to cause this to happen.

My first thought was to use the --separate-output option and somehow use grep on the results but there has to be a more elegant solution. Any help or advise is appreciated.

One of our Enterprisey systems has a long-running batch process that sometimes get interrupted by the following popup dialog:

OpenCurPrinter: printer: \\FS3\HP30351st, port: Ne00:, drive: winspool
Error initializing the printer

(where \\fs3\HP...etc... is the path of one of our network printers)

Screenshot:

I have seen a few ancient mentions of this 'OpenCurPrinter' dialog on the web, so I think its something to do with the Windows OS or printer drivers rather than the particular Enterprisey system that we are running the process in.

The OS is Windows XP and part of the batch process we are running involves emailing documents via Outlook/Exchange, if that makes any difference. Is this something to do with the way MS Office talks to printers even when its not printing?

Can anyone tell me where this dialog is coming from, and what I can do to stop it from appearing? (Its playing havoc with our batch processing)

Many thanks.

I have php, apache, mysql etc...

I am trying to view a page named "index.php", which has <php echo "hello world"; ?> in it, but instead I see a dialog box prompting me to open or save the file which is a PHP (application/x-httpd-php) file..

How can I make it render correctly?

I a CentOS 5.5
I'm on rackspace cloud servers BTW

I have yet another small issue that annoys me everyday in our Terminal Server environment.

It seems when logging into Terminal Server users report the initial File | Open or File | Save As from within an application such as Word, Excel (2003 edition) is very slow to display the actual dialog box.

The dialog appears quickly but it is whited out (sometimes displays not responding in title bar) and unresponsive, it then sits like this for about 20-30 secs before popping into life and displaying all the folders etc.

The second time you go to save or open a file it loads almost instantly.

Any suggestions or similar problems out there?
