Linux and AIX user non expiry and force password change at first login

In Linux, if you want to set the password for an account to never expire, here is the command:

# chage -I -1 -m 0 -M 99999 -E -1 username 

And to force a user to change his password upon first login:
# chage -d0 username

Current status of the account can be checked via chage command :

# chage -l username  Last password change                                    : Jun 18, 2013 Password expires                                        : never Password inactive                                       : never Account expires                                         : never Minimum number of days between password change          : 0 Maximum number of days between password change          : 99999 Number of days of warning before password expires       : 7


For AIX, to set the password to non expiry and force the user to change his password upon first login:

# chuser expires=0 maxage=0 username 


To check the username status in AIX:
# lsuser -f username




Rename a VMware VM

If you decided to rename your VMware VM, it's not just right click on the VM and rename it, as it only change the vCenter naming display and not associated virtual files and disks.

There is a long list of steps to be taken to rename a VM in VMware KB.

However, the easiest hassle free one that I found is to "clone" the target VM to new VM with your desired name.

This process will rename vCenter display name as well as all the vmdk virtual disks and other associated files to new name.

Just right click on the target VM, choose Clone, give new name and location, and wait till cloning finish which will take some time depending on the size of your VM.

There you go, the easiest way to rename your VMware VM.

Please let me know if you have an easier one in your tricks.
