General :: Different Passwords For Normal / Remote Login?
Apr 25, 2010
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)?
I'd like to know if something like this already exists :have an ecryptfs encrypted user account on a laptop that accepts two logins, 1st logs normally, the second triggers a system format
I 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.
I don't what happened but yesterday I was working normally and then I shutdown the computer, today when I opened ubuntu it took me to tyy1 login screen, I entered my username and password then it took me to the normal login screen with the login drums sound and it wrote on my account (logged in) so I clicked it and I entered my password again and then I got to my ubuntu so what went wrong and how to fix it also I noticed that a new terminal in system tools occurred called Kernel (I didn't add it)
I'm using ubuntu 10.10 on Dell inspiron 1520 with Nvidia 8600GT and 3GB RAM
Important: this happened after update to generic-headers-24
How to make a Server of LOGIN / PASSWORDS for flexible linux machines? Samba config files for the server and the client. The clients, if no network, shall use the /etc/shadow.
I 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.
How to change both the login/sudo and default-keyring passwords with one operation? If I recall correctly, to change one'slogin and sudo password, one must use `passwd` or System>Preferences>About Me>Change Passworddefault-keyring password, one must goto Accessories>Passwords and Encryption Keys>Passwords, rclick on keyring>Change PasswordIs there a way to do both with one operation? preferably from commandline? preferably in karmic?
am using RHEL 5 ,i would like the system to send me an email for every time some one attempts to login to the server remotely. i have created the emailing script in perl and it works. but i want it to be triggered if someone tries to access the server. how can this be possible
I 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.
I 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.
I wonder if it is possible to have two passwords for one user account in 9.10. I have a long login password (5 words about 45 characters with spaces caps). I would like to set a shorter password for Authentication, sudo, etc. While retaining the original for logging in.In short:Have long password to login to computer.Have short password for everything after login.
I 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 need to connect to a remote linux server on certain times (automated), but i need to log on to the server. So i want to make a script (shell perhaps) that periodically connects to the server and checks some files and folders.How do i automate it and how can i log on automatically to the remote server without typing everytime the password and login (the script should do it himself)
I 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.
Seems 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?
I am unable to login as normal user. I am sure that my password is correct. What are the possible reasons behind this and also the solutions. My /etc/password and /etc/shadow files are good and my login haven't set to /etc/nologin.
Actually this a question asked to me by a Novell(Suse Enterprise Linux) Regional manager.
