Ubuntu Security :: System Can't Remember Username Password?
Jun 4, 2011
I've been using ubuntu 9.10 for years and never been asked for username and password, always started straight away. Today I started the computer, it's asking for them and doesn't accept the password so it's trapped in a loop. I changed the password, no luck, the username when starting seems to be different from the one when I'm changing it. Something like "Mart Di", versus "mart". Tried both with new and old passwords. Does the password expireor something?

There was a recent thread in this forum regarding capturing of SSH passwords via the use of wireshark. The thread subject was closed, which is a decision that I both agree with as well as agree with the reasoning behind. The thread, however, raised a point of curiosity and concern that I would like to ask about. Quoting from a the book, SSH, The definitive guide,
The client authenticates you to the remote computer's SSH server using an encrypted connection, meaning that your username and password are encrypted before they leave the local machine. The SSH server then logs you in, and your entire login session is encrypted as it travels between client and server. Because the encryption is transparent, you won't notice any differences between telnet and the telnet-like SSH client.
I was under the impression that SSH was impervious to this type of eavesdropping, and quite frankly I take great comfort in that idea. I personally, only allow RSA keys for SSH access and (hopefully) avoid this problem (?) as a result. Does SSH really have a vulnerability in that the authentication is sent via plain text? How to ensure the security of SSH and not on anything that could be considered a how to 'crack' it.

I'm trying to use Kubuntu 10.04 in a corporate environment. Our environment uses an internet proxy that requires a username and password.Under Ubuntu 10.04, I can use the GUI to set the proxy host, port, username and password. When I do this, all the web browsers work, Snyaptic works, etc.However, under Kubuntu 10.04, the GUI lets me specify a proxy host and port, but doesn't appear to save the username and password. Because of this, I have to manually set the proxy information on my web browser, but the package managers don't work because they can't access the internet. Apparently the ability to specify proxy username and password is either broken or unfinished.

I installed ubuntu 10.10 a week or two ago. The problem I have is I installed kubuntu via synap a few days ago then I did a restart. to see what it was like. I go to log in and the login screen is different. And it doesn't have the user-name that I used saved. So I don't remember my user-name for ubunutu. I tried everything I could think of but I don't know it. I know my Password. but not the user-name. So I cant log in. How can I see the user-name I used? without logging in? in Terminal maybe??

I set up a samba file sharing system but my workgroup asks for a username and password see this-This is the text in /etc/samba/smb.conf:
# smb.conf is the main Samba configuration file. You find a full commented
# version at /usr/share/doc/packages/samba/examples/smb.conf.SUSE if the
# samba-doc package is installed.

I hate to make a new thread for something that has probably already been solved, but searching through all the threads can be a challenge in itself.Every time I log in to Ubuntu 10.04 I am asked for the password to my Wi-Fi connection. About a week ago it was working fine, however after, I think, the second update Ubuntu was longer able to remember the password. Its not a major problem as I can access the Internet its just really inconvenient.

I've got a strange issue here concerning Firefox. Of some sites i don't ant my login and password to be saved by Firefox. The question pops up (below navigation bar) i click no and it's gone. But when i go to the same website, let's say, the next day, i get the same question. This issue is not related to 1 website, it's doing with all kinds of sites i log in to.
How can i prevent that FF comes up with that question to remember my login/password even when i clicked on No, do not remember? Pleae keep in mind that some site i do let FF save my login/password, those sites are regular visited by me. So unchecking the option in preferences i rather don't want that.
Who can tell me why FF keeps coming up with that question even if i click on no?

I recently installed vsftpd on my server. I noticed that users on the machine can login into vsftpd with their username and password on the machine and go to their root dir "/home/username".Now, I want to give some people a vsftpd username and password so they can upload and download files and folders to their folder, but this folder has to be in the "/var/www/(username)" folder. I don't want them to be able to go to any other folder than their own folder like "/var", "/etc" or "/home" etc. Also I don't want them to be able to login on the machine as a user, through putty for example. They should only be allowed to acces their folder with vsftpd, nothing else.

Every time that the internet connection is lost (because of hibernating etc.) I have to re-enter the password for the router. It used to remember this but for some reason it doesn't any more.

I am running edubuntu in one of the classes of the school i support. My problem is that the children cannot remember the password for the computer if it locks. I have it set to auto login on the class user and I have disabled the screensaver asking for a password on resume, and disabled the powerdown options. So in theory it should stay on the desktop until they shutdown. However there is still the option to lock the computer and i am sure that they will find it and manage to lock themselves out of the computer! I am a linux beginner, but i have followed a few guides on the internet. I could really do with having their user with no password, so if they accidentally lock the computer they only have to click unlock to resume their computing.

A friend of mine can't remember her password for the computer.When the computer starts it automatically loads her user profile, i can't create any new users, and i cant become root with sudo, i looked around on the forums and some stuff was very helpful in teaching me more about linux, but without being able to change, or remove the password i cant update. the laptop is a dell 910 mini.
At the terminal, instead of being: User@localhost, it's : name@name

I routinely use somewhat spotty wireless hotspots, and Network Manager is driving me insane. Whenever there's a momentary drop, NM will prompt me for my password. I enter it, and it connects perfectly. And then 5 minutes later, it'll prompt me again. How do you instruct NM to remember a password, and stop prompting?

Is there any way torequire a password for anything to be installed onto my computer? For example, lately, I clicked on an image in googleimages that ended up installing something onto my pc. If a password was required for any installation, this would not have happened.

I'm running Evolution 2.30.3 on fc13.x64 and I've been getting a funny problem for a while, that now really annoys me:
even if the settings for my hotmail account are correct, Evolution will ask for the password every time I log in. Also, since I keep it open, after a while (~30 minutes) it "forgets" somehow the password and asks for the password again. This time, anyway, it won't work and I have to reset Evolution again.
Bonus question: even if hotmail is configured correctly for receiving and sending (smtp.live.com etc.), it won't send email, but will remain stuck on "sending".

I have entered my login password. But it is saying that "The password you use to log in to your computer no longer matches that of your login keyring."

I recently was able to network 2 computers at home and I wanted to make my password more secure. When I try to edit my password via System>Administration>Users and Groups, it doesn't workI am able to edit my user settings. When I change my password I enter my old one and it accepts my new one. Problem is when I try to install programs, login and do other things it only accepts my old password. How can I change my password?

When I installed Ubuntu on my laptop, I had chosen "automatic login" . So i was not asked ofr username and password everytime I switched on. I later wanted to change the settings. So I went to systems-->administration-->login window-->security. There I disabled automatic login and I reboot the computer. Now the GUI does not allow me to enter Username and password. It says "Authorization denied" at the login screen.
