To enable root login for SSH and SCP clients:
If you have physical access to the ESX host, login to the console of your ESX host as the root user. If you can only connect to the ESX host over the network, connect using an SSH client (such as PuTTY) and log in as a user other than root.
To create a user in ESX host for using a SSH client:
- Log in to the vSphere Client as a root user.
- Click Users & Groups.
- Right-click on a blank area and click Add.
- Enter a username and password. Confirm your password.
Note: Starting in ESX 4.0, the password needs to be at least 8 characters in length.
- Select Grant shell access to this user.
- Select root group from the dropdown and click Add > OK.
Note: By default it assigns to the users group and does not allow SSH access.
After you are logged in SSH session, switch to the root user with the command:
su -
Note: If you do not have any other users on the ESX host, you can create a new user by connecting directly to the ESX host with VMware Infrastructure (VI) or vSphere Client. Go to the
Users & Groups tab, right-click on the Users list and select
Add to open the
Add New User dialog. Ensure that the
Grant shell access to this user option is selected. These options are only available when connecting to the ESX host directly. They are not available if connecting to vCenter Server.
Edit the configuration file for SSH with the command:
nano /etc/ssh/sshd_config
Find the line that starts with
PermitRootLogin and change the
no to
yes. You can find this line about 2 pages down from the top.
Save the file by first pressing
Ctrl-O and then
Enter.
Exit with
Ctrl-X.
Restart the sshd service with the command:
service sshd restart
Note: Alternatively, use the command:
/etc/init.d/sshd restart
