Can we change the expiry date for root password?

Hi,

Is it possible to change the expiry date for root password by using “chage” command? As I know “chage” can be used to change expiration for a normal user. If it cannot, is there any way to set expiration for root password?

Thanks,
Brs

Hi
Not sure why you would want to do that (incase something when wrong and it expired?), but chage should work;

Don’t have a SLE 11 SP4 system, but tested on SLES 12 SP2;

chage -l root

Last password change					: May 21, 2017
Password expires					: never
Password inactive					: never
Account expires						: never
Minimum number of days between password change		: -1
Maximum number of days between password change		: -1
Number of days of warning before password expires	: -1

chage -M 99999 -m 0 -W 7 root

chage -l root
Last password change					: May 21, 2017
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

chage -M -1 -m -1 -W -1 root

chage -l root
Last password change					: May 21, 2017
Password expires					: never
Password inactive					: never
Account expires						: never
Minimum number of days between password change		: -1
Maximum number of days between password change		: -1
Number of days of warning before password expires	: -1
