Programming :: Automatic Login By Using Ssh But Without Creating Public Key?
Apr 12, 2010
I want to connect to anothere server from my current server through SSH command.
when I am using the command in the terminal like-- ssh username@ip it is asking me to give password. This is working fine in the terminal. but I want to do it automatic through a shell script.
How can I be able to provide userid and password through shell script?
I was trying to achieve it by creating a public key and copy it to the destination .ssh file. but I dont have the permission to create any file in the destination server.

Run a script on ServerA which uses a ssh-connection to ServerB to execute a few commands on ServerB. As ServerB only allows login with username+password the whole stuff gets more complex. SSH provides key authentication enabling passwordless login as you probably know. So as stated in many tutorials I did the following:
Quote:
ssh-keygen -t dsa
ssh-copy-id .ssh/id_dsa.pub osr@10.17.120.207
Trying to connect with
ssh osr@10.17.120.207
should now be passwordless but I'm somehow still getting the prompt for the password.here the output from ssh -vvv osr@10.17.120.207
Quote:
OpenSSH_4.1p1, OpenSSL 0.9.7d 17 Mar 2004
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
[code]....
interesting are probably the following lines:
Quote:
debug3: Not a RSA1 key file /users/osr/.ssh/id_dsa.
debug2: key_type_from_name: unknown key type '-----BEGIN'

I'm already aware that you can set automatic login for gdm, which is what i currently have now.
Unfortunately, for some bizarre reason, it doesn't work 100% of the time. I'd say for about every 10 successful auto-logins, I get a case where it just sits at the log-in screen. This is a problem for me because i use it for a specific purpose, and i need Ubuntu to come up as fast as possible, without any user interaction.
So far my only workaround has been to reboot it whenever it does a bad start (where it asks me to log-in) and usually when the PC reboots, it will auto login fine.
I've given up trying to find out why it does that, so i just want the log-in screen gone entirely. I've searched on google and on this site directly, but no one else seems to have this issue.

I am working currently on my server on an issue, I configured the SSH Deamon that only people who have a valid ssh-key can login on to the server, and kicked the password option. Now I've added a user account git. I navigate to his home folder created the folder ".ssh" and created in that folder the file "authorized_keys" I copied my public key in there. Now on my local machine I added that identity (via ssh-add) and I wanted to connect to my server. but when I'm trying to login myself I can't the only message I get is "Permission denied (publickey)."

I can't get this to work on my machines.
So far I have:
1. created a key with ssh-keygen on the server to be logged in to
2. copied the .pub key to my local machine
3. chmod 700 ~/.ssh on both machines
4. chomd 600 ~/.ssh/ic_rsa on the server, and on known_hosts on my local machine
5. added the .pub key to ~/known_hosts on my local machine
my local machine doesn't have an "authorized_keys" file which is what everything is telling me I should append my .pub key to. The only thing that was in my .ssh folder was known_hosts, so I tried that. I also tried making an authorized_hosts file to no avail, changing permissions appropriatly on all files.
Should I/Can I reset ssh in some way? Is there are reason I don't have an authorized_keys file or is my known_hosts file my authorized_keys file?
Would it be better just to uninstall/reinstall ssh?

To enable automatic login, I edited the /etc/gdm/custom.conf file and entereted the following lines:
Code:
The automatic login is working but I still see the login box with options to select language. After a delay of few seconds, the system will automatically log me in. I don't know why I see the login window. Is there any way to bypass this window?

My laptop running Ubuntu 10.04 insists on automatically logging me in without asking for my password. The only thing is, I've disabled auto login and it shouldn't be doing that.
When I first boot up Ubuntu all I have to do is select my username, no password required to log in. I want the login screen to prompt me for my password for better security.
Here are the settings I already have:
System - Administration - Login screenSet to "show the screen for choosing who will log in"
System - Administration - Users and GroupsI am the only user I have an Administrator level account "Don't ask for password on login" is unchecked, i.e. it should ask for my password on login. If I create a new user with the same settings, that user gets asked for its password. But I don't.
Surely this should be enough to disable automatic login.

I have enabled automatic login in Lubuntu, and have now added a second user, I want to DISABLE the automatic login, or perhaps change the default login. The usual Ubuntu admin window for this does not appear to be available. Where in the conf files this setting is, and or whether there is a GUI that controls this.

recently installed Ubuntu Server 10 everything has set up just fine but the only problem i have is to get ubuntu to login automatically. The main reason for this is because i havent got a monitor connected if for whatever reason the server restarts its hanging at the login screen and i cant login via vnc to the desktop. The furthest ive got is for it to say at the login screen next to the name (user logged in). Any Ideas on how to resolve this? or if it is possible?

I have installed CentOS 5.5 successfully and I have VNC working. This server will be a headless box that will reside in a server rack. I intend to perform any necessary maintenance on the machine remotely though my desktop computer. My problem is that when CentOS is on the login screen, I cannot connect with VNC. Once I have logged into a user account, then I can connect.
I would like the server to automatically login to one of my users each time it boots so that the VNC connection will be opened. Currently I have two users, root and Zachary. I would like the server to automatically login to the user Zachary.
In the CentOS Gnome GUI, when I go into System > Administration > Login Screen, and then click on the Security tab there is an option to "Enable Automatic Login." If you check this box a select form field becomes active; however, there are no user accounts showing in that select field. I tried typing in the user name that I wanted to automatically login, but after closing the screen it clears that username. What am I missing?

I have a problem with my ubuntu account. I am running 4 virtual machines, based on jeos-8.04 and I am using a public key authentication to login to my account (via ssh). This is not the problem, I have the key and the passphrase. But when I am logged in, I can't sudo, because I forgot the password for the accout.

I've tried to ssh in as the root user w/o a password (RSA keys) but I've had no luck as the root user. I've tried the exact same commands with Debian 5 and Centos 5.5, without a problem. Fedora 13 and 14 won't work! I can only log in w/o a password as a normal user, never as the root user! It always asks for the password if I try as root. I've even tried copying Debian's and Centos's sshd_config file and restarting sshd, but it still won't work.
Code:
mkdir ~/.ssh ~username/.ssh
chmod 0700 ~/.ssh ~username/.ssh
echo "ssh-rsa AAAAB............Jw8V03loeZ username@thehostname" > ~/.ssh/authorized_keys
[code]....

I made my Fedora 13 box boot up automatically by adding the following to /etc/gdm/custom.conf
Code:
However, when it boots up it prompts me for my password so it can connect to my wireless network (I think it said something about not getting my user password at login). Is there anyway I can get it to remember this?
I would like to make this automatic because this will be a remote box that I will use as a file server, but it wont be turned on all the time. So I'll turn it on when I need it, but I'll need to connect to it remotely, so obviously it needs to be on the network.

When I create a new user account and login the first time to Gnome a series of files and directories is created in the user's home directory. Those directories are for example:
.ICEauthority
.cache
.config
.dbus
.gnupg
Bilder
Desktop
Documents
Musik
Videos
Vorlagen
�ffentlich
How can I control what files and directories are created? I checked /etc/skel but none of those entries where there. In particular, I do not want to have the folders "Bilder", "Documents", "Musik", "Videos", "Vorlagen" and "�ffentlich" being created.

I've just installed Ubuntu 10.04 desktop. I've created two user accounts, one for admin purposes and the other for standard users. At boot up, I have the option to pick one of the created accounts or select "automatic login." When I select automatic login, it logs me into the admin account. I've double checked that the "don't ask for password" option is not selected on either account.
The only thing unusual that I did was select the "don't ask for password" option during the install, and then later (after the install was complete) decided that's not what I wanted and unchecked it.
I need to accomplish one of two things. Either change it so the auto login applies to the standard user account, or remove the auto login option from the login screen altogether.

After changing my user's UID number with the "usermod -u" command or otherwise changing the login settings my computer no longer logs in automatically. I can login manually by selecting the "Other" option and manually typing in my user-name and password. However my user-name is gone from the list of users at the login screen or in the Login Screen Settings program.
Other than that my computer seems to function fine. My users details are still listed in "User settings".

I have a windows 7 ultimate host machine, installed oracle virtual box on it. Made a iso image to boot fr fedora. All this is fine when the installation is complete, it asks for reboot. Reboot done. Then I went to terminal. Did a SU - root to get into the root. Then I did a firstboot command to enter information. I created a user for myself and at the end rebooted the virtual box.
When it starts up, it does not show my user. It just shows "Automatic Login" and it logs in as Live System User. Even if I try to switch user then it gave me a authentication failure when I enter the credentials of the user which I created. If I try to create users manually using system administration, the user is lost after reboot. I have tried all possible steps...as instructed on the net.

I'm setting up a mythTV frontend, so have set up automatic login in GDM, which works perfectly. I've also re-enabled the "kill X server" key combo (ctrl-alt-backspace), as other people here are used to that to restart it if everything goes pear-shaped.
However, the autologin isn't working properly after I kill the X server -- just sits at the login screen, and I have to manually log in.
how to fix that? Essentially, I never want to see the log in screen -- I want it to always log in as my generic MythTV user.
Not sure if it's any help, but here's my /etc/gdm/custom.conf:
Code:
[daemon]
AutomaticLoginEnable=true
AutomaticLogin=generic
TimedLoginEnable=false
TimedLogin=generic
TimedLoginDelay=1
DefaultSession=gnome
(I've also tried enabling the "TimedLoginEnable", and have tried delays of 0, 1, and 10 seconds. They don't seem to work, either.)

Is there a way to set Linux to automatically log in to a specific user account and at the same time lock the screen? I want to save time and trigger various software that always should start up on boot, while leaving the computer unattended during startup (extra important and practical for remote control boots), by enforcing a 'screen lock' so that no-one can see what happens behind the login screen without entering the login credentials.
