Is it possible to have multiple passwords on the same account, where one password allows only normal login and another only when accessing the machine remotely (for example, via ssh)?

View 1 Replies View RelatedI just recently upgraded from 10.10 to 11.04, but using the classic desktop instead of unity, mainly because unity sucks big time, but that's a different story, anyway, when I used 10.10 I had a key setup for access to my remote SSH server, but now when I try to set up a new key using passwords and encryption, I get:- "Couldn't configure secure shell keys on remote computer", followed by:- '** (process:2532):WARNING **:couldn't open fd 27:Bad file desciptor' 3 lines of this with different process numbers then I got ''** (process:2535):WARNING **:couldn't open fd 27:Bad file descriptor: Permission Denied. Please try again'
I have not changed anything on the remote server at all. I can access SSH using PuTTy sucessfuly, but I want to set up a key using the ubuntu passwords and encryption key program, but since ugrading to 11.04 I can not do that for some reason.
i am looking for a detailed description of the login process for both root and normal user , also locally and remotely.i read some sentences that the files .bashrc and bash_profile are needed for this process. But that was very concise.

View 10 Replies View RelatedI maintain plain vanilla Ubuntu 10.04 systems for several friends. Each machine has only one user, the owner. I use Remote Desktop to instruct and to perform maintenance. Here's my problem:After updating the system, if the kernel has changed, a restart is needed. If I do a restart, I then have to phone the owner to insert his login credentials in the gdm login screen, before I can do anything else via Remote Desktop on that machine.There ought to be a simple way I can avoid the phone call and login myself.
I'd strongly prefer not to use any software that is not included in a plain vanilla Ubuntu 10.04 installation. And I don't want to weaken system security beyond what it is now.Is there a solution? Or, what is the simplest solution?
While I've been using Linux for a little while now, I have only recently been getting into setting up and using a server at home (in part because until recently I only had ONE computer at home). I have heard of LDAP and OpenLDAP, but I am not sure if this is the best tool to do the following. Centralize logins and passwords for all of the computers at home, so I only have to change/manage one place. Since I keep installing Linux Distros it would be nice if I didn't have to add each person, individually each time.
Provide single sign-on authentication for the user so when they go to the Samba server they don't have to do another login, but they are limited in what they can see. Basically I don't want the kids being able to see *MY* files
- Works with Linux (various) and Windows (Windows 7 more than XP)
- Works with desktop and laptop
- Be able to, possibly, pass this authentication to the web server so likewise do not need to log into the web server after logging into the computer.
- (optional) be able to set up a script to run automatically to either map network drives or mount samba directories based on the user being logged in (smb://user/<username>) and/or backup the system.
I say optional because if it can that is great, but if it cannot then it isn't a show-stopper. Like I said, I am very new to servers and networking and do not know where to start regarding this. Right now I have a basic (too open) file server and a web server just beginning to be developed (working on Drupal). Not only do I need to figure out what/where to research about the server settings but also setting up the client-side of things.

View 9 Replies View RelatedI hope this is not a totally ridiculous question. I use putty often to remotely connect to my laptop at home. I recently learned about the Linux framebuffer, and was curious if there was a tool like putty that would let me remotely connect to my laptop but use the /dev/fb0 device for forwarding graphics. Sort of like a vnc or X11 forwarding, but instead of using X, gdm, kdm etc. we use the framebuffer.
View 2 Replies View RelatedI know I can ssh login without password from a local to a remote. My question is how I can ssh without password from the remote to another remote. Say, I have three machines: A, B, C where A is the local machine. I use the same private/public key pair for all the login. What I can do are:
1. ssh from A to B.
2. ssh from A to C.
3. If I am sitting in the computer B (or B is local), then I can ssh from B to C.
What I am not able to do is:
After I ssh from A to B, I cannot ssh from the B to C. When I try to ssh from B to C, it asks me a passphrase.

View 6 Replies View RelatedI was under the impression the Linux (in my case the Fedora OS) is very secure. However I've learnt with deep concern that that one can have access to the system during system startup i.e one can give various startup directives and bypass the normal login UI to have direct root access.
Is there a way to disble this so that the directives during startup are fixed and cannot be altered. I would like to make the system secure to the maximum extent possible.
i'm using OpenSuSE 11.2 and was wondering if there is anyway to set remote login as the default login method.

View 14 Replies View RelatedI am having a funky issue at login. When I enter my username/password at login with the GUI (I disabled the list of users some time ago) the screen will flicker then return me to the login screen. There is no notification of an error. It doesn't matter if I try the recovery console or safe mode there is the same issue when I try and login with this user. However, I can login with a different user open a console and su to that user that wouldn't login at the GUI.
View 3 Replies View RelatedSeems that I have been having a problem with the initial user login on Ubuntu 10.10 Netbook. Whenever I try and login the normal way (from standard gui login) my system comes to a standstill and I have to switch to command line (ctrl+alt+F2) and restart/shutdown my computer in that fashion. The only way that I can login and actually see my desktop without any hint of my system freezing up is by booting into the ubuntu recovery Console using the dpkg function to remove any broken packages, select boot normally (where I have to login through the command line), and manually startx.
Originally I was running an x64 version of ubuntu desktop 10.10 but I switched to an x86 version of netbook due to many incompatibilities in software and trouble finding x64 software for my system. When I was on Ubuntu Desktop I had a similar problem where it would freeze at login as well but I fixed it by removing compiz & compiz-core. I tried that with this version of the OS but had no luck because it said that compiz was not installed.
Not a major issue, just somewhat annoying that I have to resort to other means to login
PS: My computer is a Toshiba P500-026. Some stats are listed below in my signature if its relevant to my problem.
i have to reinstall my pc with a testing version. The installation almost is the same as stable version (lenny). But, the problem is that, i can't login it after the installation completed. The new user i created during installation is invalid! So, i have to enter the single user mode, to my surprise, the new user(i created before) doesn't exist! So, i add a user here.But, i still can't login to my system as the normal mode.How should i resolve such a problem?
