I'm using ssh key based authentication and I was pleased to find that when I set it up out of the box when I connected to my ssh server it prompted me with a password window rather than typing into the terminal and it remembered the pass phrase from one connection to the next.
For some reason it's stopped showing me the window, instead I'm logging in through the terminal, and it's stopped remembering my pass phrase between connections. since I don't know what the program was called that gave me the login box it's rather hard to search for.

Some of your private key files are encrypted for security reasons. In order to read them you have to provide us with the pass phrases. Server your.server.com:55 (RSA)
Enter pass phrase:
Server www.blahblahblah.com:55(RSA)
Enter pass phrase:
How to login ?
The cursor is blinking but I am unable to enter the pass phrase; the only thing I can do is press the power button to shutdown. Even if I leave the PC running for a hour I can't type anything.
I know how to resolve the problem if I am able to login.

I updated Lucid yesterday, and when I restarted the user interface was changed to a more simple feeling display. This makes me think I'm stuck in a "basic" mode or something. I attached a screen shot, but to give you an idea ill describe some issues. For one thing the minimize buttons are now on the right. The volume control, which used to appear on the top right of the screen, is gone and my multimedia volume control buttons on my Inspiron 1420 no longer work. Furthermore, the command terminal is now white and the keyboard shortcuts for copy and past don't work.
Immediately after updating I also got an error message at login (which also appears different and gives options on bottom of screen like gnome Failsafe) which said something like "gnome default power management installed incorrectly...". I followed the advice of a forum thread that involved the purge command and that seemed to remedy that message.

I need to be able to use an rsync command in script that will be run by cron. And it needs to be able to pass a password to rsync so that the remote server it's connecting to will authenticate.
I cannot set up ssh keys between the two servers, it's not an option. I cannot use any other language other than bash, it's my only option. I know this is highly insecure, I have no other option.
So far I have this:
rsync --rsh="/usr/bin/ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -o PreferredAuthentications=password" -raxv /source/dir/* user@remotehost:/target/directory/.
This allows the script to ignore host verification and goes directly to the password prompt. I need the script to fill in this password prompt with the password that is stored in a variable.
I tried using expect, but I honestly don't know the syntax, it just keeps failing. A lot of the examples I'm finding online for expect starts off with a "spawn", which i don't have installed, and not sure if I have the ability to install it yet.

I have been put on the task of changing the passwords of two user accounts on one of our debian boxes at work. The problem is that the current passwords are unknown, and I only have SSH access to the machine.
Is there anything I can do?
I thought about simply creating two new users and removing the old, but that may not be an option.

I'm trying to do a shell script which are suppose to run a program as a specific user at system boot up. The problem is that I don't know for sure how to make the script add the users password to the prompt when it's necessary.
Basically the program would be run like this:
sudo -u extrema program_name -r /srv/program_name -d
and in this example the password is, "hidden".
How would I make this script run this program as user extrema with the password "hidden" at boot-up? I know how to put the script in the rc.X directory and so on, its more the syntax of the code.

At the RHEL prompt, I entered the standard user's username/password combo. Linux displays a message box stating:"Your account has expired; please contact your system administrator."Next, I entered "root" in the username field and entered the root password (which expired also--keep in mind that passwords are set to expire after x days). Linux displays a message box stating:"You are required to change your password immediately (password aged)."When prompted to "Enter current UNIX password", I entered the new password (was that the right thing to do?); Linux displays a message box stating:"The change of the authentication token failed. Please try again later or contact the system administrator."I rebooted the system and got into command line mode; somehow I logged in as "root" (don't know exactly how, but needed to change the password there). At the "#" prompt, I type "passwd root"; Linux displays the message "Changing password for user root", followed by the message "passwd: Authentication information cannot be recovered.

One may argue that Debian is going mainstream being officially supported by Linux Mint. The chances are high that many users may change from the Ubuntu to the Debian base. By now especially Ubuntu's PPA has grown to a huge respository offering almost anything an user would need. But how does that look like in a Debian world?
There are several approaches to establish a "Debian PPA", amongst them debppa, but there activity is low not to say that they are almost inactive and orphaned. As coming from an Archlinux and Ubuntu perspective I do not know the Debian perspectives enough to reason this but am still curious to know about your motives not establishing a userbased repository.
