I suppose that, yes, this will "prevent password aging."

It will also prevent the user from being able to log in (and is equivalent to # passwd -l user).

If you mean that you do not want the password from expriring (aging out), you could use:

# chage -M 99999 <username>

99999, incidentally, is the default value, derived from the /etc/login.defs file when the user account is created (which can be set to something different by changing PASS_MAX_DAYS in the file).

It's 99,999 days - 274.78 years - so, unless you wanna live for another 274.78 years, it effectively means your password will never expire.

update: I just double checked the man pages for chage, and it says this, "Passing the number -1 as MAX_DAYS will remove cheching a password's validity," so this appears to be the better coice (in case I do live longer than 274.78 years):

# chage -M -1 <username>

I was trying to lead folks!!!
