Installation of Lexmark S305 Network Printer

I am a new Ubuntu user and Iam attempting to install aLexmark S305 Printer. I have downloaded the appropriate installation software. I get so far on the installation and I get a request for root(administrative) password I have used the password that I sign in with to no avail. My question is what is the root password and how do I access it.



init error, laptop wont boot?


I turned my computer on and it comes up with ways to boot and I clicked Ubuntu with linux 2.6.38-13-generic. There was a recovery mode too. Once I clicked its writing come up:

init: udevtrigger main process (93) terminated with status 1
init: udevtrigger post stop process (97) terminated with status 1
init: udevtrigger main process (92) killed by TERM signal
mountall: disconnected from plymouth
init: plymouth-splash main processs (98 ) terminated with status 2
init: plymouth main process (50) killed by SEGV signal

I have no idea what this means and my laptop don't boot. I tried recovery mode but it comes up with similar things. I don't know why this has happened. It can be because I tried upgrading my Ubuntu to 11.0 and I shutdown the laptop before it finished? i would be most grateful if you could help

"Authentification Token manipulation error"

So I just bought this computer off Craigslist with Ubuntu on it.

I was a complete retard and changed the administrator password and forgot it among people coming in and out of my room.

I followed this http://www.psychocats.net/ubuntu/resetpassword

BUT, every time I tried to put the password in for the second time to confirm it, I got this thing saying "Authentification Token manipulation error" or something to that effect. What is this and how can I easily fix it?

Remember, I am completely new to this and dont understand ANY ubuntu lingo, so please be explicit.



when I install Ubuntu 11.10 will it remove all the drivers that are on through windows xp pro? And then reinstall it's own drivers back (for the ones it removed)under ubuntu 11.10 format.

I am in the grey zone here wheather to install it or leave it alone.Wont do any good to have a laptop with a new OS and not be usable because the new OS wiped out the drivers and the thing wont work.

Thank you for any and all advice and help

Panels in Xubuntu--2 on top, 2 on bottom.

I was trying to install Force Quit and a couple of other applets on the top panel of Xubuntu.
Suddenly I had no more Xubuntu panel, but an empty panel. After some search I found the two legitimate panels located under two inactive panels, like those in the new Ubuntu 11.10 distribution. I was able to make the legitimate panels larger with panel preferences and therefore have the use of Xubuntu. Still the two dummy panels are under the legitimate panels. I would like to get rid of the two extra panels which only showed up as I was installing Force Quit and another couple of applets. I would appreciate any suggestions. I can re-install if necessary, but I have been doing this for the two years I have been learning Linux. Any time I couldn't solve a problem, I would re-install. Any help greatly appreciated.


Password Guessing with THC-Hydra

Hydra is available for Windows and Linux. I’ve used both, however if you have the need for speed, Linux is the way to go. I’m sure you’re itching to get started so I’ll stop yapping.

Hydra in its most basic form requires 4 items;

1. target IP address
2. user name (to be used during login process)
3. password (to be used with above username)
4. service (to be brute forced)

hydra -l administrator -p password ftp

However this isn’t much fun, not to mention time consuming. Who wants to re-issue the following command over and over again manually.

Instead you can utilize a text file and store passwords you want to try. Hydra can pump through a large text file in minutes.

The easiest switches to remember are -l / -L and -p / -P

Password guessing as an attack vector

Over the years we've been taught a strong password must be long and complex to be considered secure. Some of us have taken that notion to heart and always ensure our passwords are strong. But some don't give a second thought to the complexity or length of our password. Password guessing in my view is the oldest hack in the book, and unfortunately some of us are making it too easy for the bad guys. From simple things like password equal to username (I still see this often) to blank passwords or super easy combination's like 'qwerty'. As a system Administrator it is our job to serve and protect. However, despite our best efforts users often give things away too easily. Therefore how do we know our users are doing the right thing and how can we audit poor or weak passwords.

Both panels acting weird

I'm using Ubuntu 11.04. My panels both top and bottom have times when they show solid system colors and other times when they become transparent or partially transparent in the middle allowing desktop to be visible. Is this some kind of bug, worm, or Trojan, etc...?
