The useradd command will let you tune password expiration times per user.. but for creating complex passwords, you could always create your own modified passwd tool that users have to use to enforce your complexity. As for having the last 4 passwords not used, I'd probably end up creating a database of some sort that my custom passwd tool would tap into. There are probably solutions/built-in's already that take care of this, but that'd be my first thought (I usually think about what I'd do before searching for already existing solutions). I'm interested to hear what other people use/would use to handle this :D Chet On Mon, Jun 30, 2008 at 12:19 PM, karthik keyan <karthik_arnold1@xxxxxxxxx> wrote: > Hi All > > I would like to setup passwd complexity on our Linux servers . > > Min 8 characters - 1 upper , 1 digit and 1 Lower character > > Last used 4 passwords should not be used > > And also i want to set Passwd expiry for user accounts which are already > created and These passwd complexity should apply to users which has alreay > been created . > > I Need your valuable help and advice > > Thanks & Regards > Karthik > > > > > -- > redhat-list mailing list > unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subjectunsubscribe > https://www.redhat.com/mailman/listinfo/redhat-list > -- ---------------------------------------- chet nichols III chet.nichols@xxxxxxxxx aim: chet / twitter: chet http://chetnichols.org ---------------------------------------- -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
