View Full Version : [ubuntu] Classified, internetless Ubuntu installation

April 26th, 2008, 12:39 PM
I am tasked with setting up Linux on a machine that has no internet and has strict security requirements. I have done a bit of googling, but have not yet found anyone else who has done this. Am I the only ubuntu user that's tried to use it on classified machines? Apparently, SuSE and Fedora can do this easily, Ubuntu cannot. I need help with the following:

1) I need to be able to enforce strong passwords, and they must be changed every 3-6 months. This is not the same as TELLING them to pick a strong password, and TELLING them to change it. The system must enforce it. I got one lead on using passwdqc (libpam-passwdqc) but I'm not sure how to set it up appropriately. I suspected maybe I'll link /usr/bin/passwd to /usr/bin/passwdqc or whatever it is. But that doesn't solve the passwd-frequency problem...

2) I need a login banner. When the machine boots into the login screen, there must be a window that pops up with all this jargon about being arrested if you are unauthorized to use the computer and you agree to be monitored, etc. I am pretty sure this must be a window that pops up and requires you to click "OK." At least this is how they have it on Windows. I might just change one of the theme backgrounds, and add the text above the login box...that might be sufficient.

3) I need the first computer I set up to act as a repo-server to distribute, among other things, security updates once a week. I know this is possible, but I haven't quite figured out how to do this. I know it will involve setting all the other computers /etc/apt/sources.list to a local server IP address, but I need to figure out the server part. For xferring packages, I found things like apt-move and APTonCD but I'm not sure that's going to complete the server functionality.

4 (OPTIONAL) I'd like to clone the machines once they are setup properly. I found
this (http://www.ubuntu-unleashed.com/2007/09/remaster-and-clone-your-ubuntu-install.html). Has anyone tried this? Any other ideas?

Long post, I know. But I think if I can do this, I will have significant impact bringing at my office, bringing Ubuntu to a bunch of engineers who otherwise never even knew what it was. I'm excited about this opportunity.

It looks like I'll be defaulting to SuSE which already has this functionality.
