{{Note box|Please be aware that the current available version in the smecontribs repo is broken. Please see [[Talk:Random_Strong_Password_Generator|'''here''']] for how the code should look like. Install the contrib and change it to match the code}}
The installation procedure for both SME 8 and SME 9 are the same. To install ''randpw'' enter the following command as root:
yum install randpw --enablerepo=smecontribs
To install ''randpw'' enter the following command as root:
yum install randpw --enablerepo=stephdl --disableplugin=smeserver
After installation the ''randpw'' tool is immediately available to be used.

== Usage ==
== Usage ==
The ''randpw'' command requires an positive number argument. This number stands for the length of the to be generated password. Although any positive number can be given, a sensible length for a password should be considered. e.g. SME user passwords have a minimum length of 7 and the MySQL root password has a length of 70. Obviously a user password length is limited to what is humanly reasonable to remember, where as automated mechanisms that require a password, such as site to site VPN connections or the above MySQL example, can have longer, and thus stronger, passwords.

Failures to generate a password are being logged in /var/log/messages. This may be helpful if a certain routine passes a non valid argument to randpw.
