Updating Linux System Account Password After Expiration

How to Put the System in Maintenance Mode

Important: Before updating the system account password in a Linux system, it is important to put it in Maintenance Mode.

1. Navigate to the Linux System where the system account password change is to be performed.

2. Click on the Tux icon to the left of the system hostname/IP.

Note: Tux is the name of the penguin character that was created to officially become the Linux kernel brand.

3. Click on the Maintenance On option to put the Linux system in Maintenance Mode.

Note: If the Linux system is not in Maintenance Mode, the gateway will continuously attempt to log in using the old password. This will lock the system account before the new password is passed on to the gateway. As a best practice, always ensure the maintenance mode has taken effect before changing the password.

  • Putting the Linux system in Maintenance Mode is the best way to update a system account password that has expired because it always clears the specific app cache. Whereas a gateway rehash clears everything (i.e., all applications and all class/object caches)

  • The customer can only perform the maintenance mode method. However, should there still be an issue, ITC Support will need to perform the gateway rehash to do a force for all.
