Feature Details

Password Policy Engine

Webconfig Menu: Directory|Setup|Password Policies

ClearOS Password Policies The password policy engine allows an administrator to enforce password policies:

  • Password minimum length
  • Password history
  • Password maximum age (expiration)
  • Password minimum age
  • Password strength

This feature is mostly functional in the alpha, but there are some rough edges. If you do not see the password policy engine in the menu system, you can install the module with yum install app-password-policies

Network Traffic Analyzer

Webconfig Menu: Reports|Network|Network Traffic

The network traffic analyzer gives you a view into what is going on at the network level. This can be a handy administrator tool for:

  • Locating virus infected desktops sending out spam, viruses, etc
  • Pinpointing network hogs (who is downloading that HD movie?)
  • Checking for unusual network activity

To install the traffic analyzer, run yum install app-jnettop

You can manage these aliases through the usual User Manager found in webconfig. The adjacent screenshot shows two aliases for username tim:
