How do I remove a Linux Eterm user via the command line?

Warning: As always, please exercise caution and follow best practices when performing system maintenance, especially when initiating processes that can potentially delete data.

Easy Procedure: Remove a User (Recommended)

Log into your server as root
Remove the user (where username is the user you wish to remove):

userdel username

If you prefer the graphical interface, you may perform the same function via the GUI.

Advanced Procedure: Remove a User and Home Directory

The above command does not remove the user’s home directory, because it often contains important database files. If you would like to remove both a user and their home directory, you must first verify that your users are not configured to use the database directory as their home directory:

Log into the server as root
Verify the user’s home directory (where username is the user whose home directory you are checking):

echo ~username

If the output displays /u2/eclipse or anything other than /home/username, do not continue. This user’s home directory is the shared database directory. You must use the procedure above to remove only the user. Contact Eclipse Support with any questions.
If the output displays /home/username, you may proceed with the procedure and remove the user and their home directory:

userdel -r username

How do I disable a Linux Eterm user via the GUI?

In most cases, there is no reason to remove an OS user. It is better to simply lock down the account to prevent any future login.

Select System -> Administration -> Users and Groups
Select the user from the list
Select the Properties button
Select the Account Info tab
Select the checkbox next to Local password is locked
Select OK

How do I change the Linux root password?

If you need to change the server’s root password:

Log in as root using PuTTY
At the root shell prompt (# pound sign), type passwd and hit ENTER
Follow the prompts to set your new password
When finished, type exit to exit the shell.

How do I access the Linux GUI via VNC?

VNC is a remote desktop protocol similar to Microsoft Windows Terminal Services or RDP. The server must be powered on and running Linux for VNC to operate.

First, you must have a VNC viewer application for your PC, Mac or mobile device. In this example, we’ll be using the free RealVNC viewer.

Launch the viewer and enter your server’s IP address, followed by “:1” to signify the VNC service listening on the first available port and press Connect:

When prompted, select Continue:

When prompted, enter your VNC password:

You will now be at the GUI desktop. When you are finished, just close the VNC window to end your session.
