Using pam_tally on an RH 7.2 (2.4.18-19.7.xsmp) server, i have updated system-auth to lock users account for those who attempted 6 or more consecutive unsuccessfull logins. This works. What I'd like to do now is have those accounts disabled for 30 minutes and be unlocked when the 30 minutes passes.
So far I've been unsuccesfull in doing this, any suggestions/links/comments on how to do this is greatly appreciated.
Apologies for the plug but pam_abl[1] will do this and also do IP based locking which is typically more useful than account based locking in the face of brute force attacks.
