Need pre-login banner/text, how to setup?

Compuwiz · 06-28-2006, 03:52 PM

I have done some searching and came to this website:
http://www.puschitz.com/SecuringLinu...ngLoginBanners

Which mentions methods of making a pre-login banner. I tried following the directions for the text login banner, and that works, but when I follow the directions for the graphical pre-login banner, I get cut off.

Quote:

For GDM you could make the following changes to require a user to acknowledge the legal banner by selecting 'Yes' or 'No'. Edit the /etc/X11/gdm/PreSession/Default file and add the following lines at the beginning of the script:

if ! gdialog --yesno '\nThis system is classified...\n' 10 10; then
sleep 10
exit 1;
fi

I am using Suse 10 and Fedora Core 5; need to set this up on both.
On both Suse and Fedora, the /gdm/ folder of the /etc/X11/gdm/PreSession/ path does not exist.

I also went here:
http://penguincares.no-ip.org:9090/archives/000356.html

Which mentions "Displaying Login Banners", but the website cuts off short and does not display this section.

Thanks.

I use gdm on Debian Sarge. I just put the message in /etc/gdm/InfoMsgFile. Then uncomment and edit the line in gdm.conf

Code:

InfoMsgFile=/etc/gdm/InfoMsgFile

more shows that line about 80% through the file. Hope this helps...

Edit: I actually just realized that I also have an /etc/X11/gdm directory that contains the same stuff. I don't know which is used by default, and it looks like I just put the message in both...

Edit2: nevermind. /etc/X11/gdm is just a symbolic link to /etc/gdm...

As I said in my first post:

...I was actually wrong here. Fedora DOES show up, Suse does not.

In Suse when I go to Yast2> System > ect/sysconfig Editor > Desktop > Display Manager, the configuration file in /etc/sysconfig/displaymanager shows that it is currently using gdm as the display manager. My question, if it says it is using gdm, why is there no gdm folder where it is supposed to be?

In /etc/X11/ I DO have an xdm folder, but no "PreSession" or "InfoMsgFile" folder.

I think I should be able to get my Fedora to work, just having some struggles with Suse.

I did get the pre-login script to work on Fedora, yay! Now I need to get it working on Suse. The login banner needs to have some kind of authentication (yes if they agree and logs them in, no it waits 10 seconds and prevents login).

That is what the if statement in my first post does.

Can't you use the graphical configuration tool ("gdmconfig" or "gdmsetup")?

I checked out the graphical configuration tool like you said with that link. The section that talks about gdmconfig and gdmsetup reference the "gdm" folder at multiple places, and Suse does not have it in the specified locations. I think that website that you gave me was based off of Fedora's gnome.

In Suse when I go to Yast2> System > ect/sysconfig Editor > Desktop > Display Manager, there is a "KDM_Greetstring" field which has the description of "Special greeting words in kdm." I tried putting a test message in there, save, logoff, login, and nothing. Which does make sense, because within the DISPLAYMANAGER field, it says its using gdm, so the kdm greetstring should not work either way.

I am starting to think that Suse cannot have a pre-login banner, and maybe only Fedora?

Hi:

In SLES10, SLED10, and Suse 10 go to /etc/opt/gnome/gdm and edit the file gdm.conf -

Find the line:
#InfoMsgFile=

uncomment it and point it to the text file you need displayed.

Later -
