http://unix.stackexchange.com – What am I missing? I change the root password on a unix machine, then try to log in with that password. PasswordAuthentication is set to yes in sshd_config and the sshd daemon has been restarted. This behavior happens whether I log in remotely or locally: root@ip-10-0-0-155:~# passwd Enter new UNIX password: Retype new UNIX password: passwd: password updated successfully root@ip-10-0-0-155:~# ssh root@127.0.0.1 root@127.0.0.1's password: Permission denied, please try again. root@127.0.0.1's password: (HowTos)

Stories similar to SSH login as root fails, but I'm sure I entered the right password

Messed up password 36 weeks 6 days ago

I am unable to change my password even in root (recovery mode), or to unlock it. I can still access my account, but without password protection.

As part of trying to implement a security measure in my root ssh session, I'm trying to devise a method of starting a script after n seconds of root user login, and change the user password and logout the user automatically.

I'm getting stuck at trying to change the password silently.

hi all,

i am trying to change the password of a user as the same is used in various deployment scripts but when chnaging the passowrd to desired one by root user i am getting as below

Code: Changing password for user tcms. New UNIX password: BAD PASSWORD: it is based on a dictionary word Retype new UNIX password: passwd: all authentication tokens updated successfully. it is showing as al

After upgrading the os from 5300-06 to 5300-11, this weird behaviour happened.

My system had another unix account, let's call it "abc", purposely configured its uid to 0 for working as a root with all its authorities.

I forgot my Ubuntu password so I booted into recovery and dropped into a root shell prompt and this is what happened:

root@username-PC:~# passwd username Enter new UNIX password: Retype new UNIX password: passwd: Authentication token manipulation error passwd: password unchanged

I am user xyz on redhat linux VM abc.

I cannot change password.

abc:/home/xyz>passwd Changing password for user xyz. Changing password for xyz (current) UNIX password: Password changes on the command line are not supported.

Bit of an odd problem. I've got a server I can SSH into as one of two logins: root or erik. Once I've logged in as erik I've tried to switch to the root user:

# sudo su - root Password:

And entered the password. After several failures I thought I might have forgotten.

While studying "Learning the Shell" As I try terminal entries, I GET 'Permission Denied". Then I try "su" to become the root user. When I use the password that I entered as I installed Ubuntu 11.04, I get Authentication failure.
