The Ubuntu 14.0.4.1 virtual server is re-installed through VirtualBox. When the root account is used in SercureCRT to connect to Ubuntu14.0.4.1, the message "Password Authentication Failed, Please verify that the username and password are correct. "re-enter the password, repeatedly check the password multiple times and re-enter the correct password, or prompt the same error.

Solution

1. log on to the VM terminal using the root account and edit the/etc/ssh/sshd_config file.

vi /etc/ssh/sshd_config

2. Locate the Authentication configuration section, change PermitRootLogin without-password to PermitRootLogin yes, and save the settings.

# Authentication:LoginGraceTime 120#PermitRootLogin without-passwordPermitRootLogin yesStrictModes yes

Note: sshd_config is the ssh configuration file. The PermitRootLogin option is used to configure whether to allow the root user to log on. The default without-password indicates that the password is not allowed for full login authentication, yes, root login is allowed.

3. Restart the ssh service to connect to the server through SercureCRT.

service ssh restart
