List, It's amazing the soon the messages on this list are answered, I am glad and I want to thank you all for that... Here is my question, I have a DataBase CentOS server working with about 150 users connected via ssh, so I want to set up for all users strongs passwords, I mean, 8 or more caracters, with ,.;* , ect....... Is there some option, bash command which do that? Is there some HOWto, tutorial, rules about securing, monitoring users with access to the bash shell? (They login via ssh). Regards, Israel Garcia
