Webconfig Menu: <navigation>Directory|Setup|Password Policies</navigation>

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

Webconfig Menu: <navigation>Reports|Network|Network Traffic</navigation>

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

Webconfig Menu: <navigation>Directory|Accounts|Users</navigation>

Mail aliases are now part of the ClearOS Directory (LDAP). Why is this a “Good Thing”? With mail aliases in the Directory, it is possible to integrate alternative mail solutions including Google Apps (to be released later this year) and Zarafa. You can manage these aliases through the usual User Manager found in webconfig. The adjacent screenshot shows two aliases for username tim:

• thorton
• tim.horton

Webconfig Menu: <navigation>Network|Firewall|Custom</navigation>

Though most administrators will be able to accomplish all their firewall needs using the standard ClearOS web interface, it may be necessary to add custom firewall rules in some scenarios. The Custom Firewall Tool provides a way to create advanced iptables rules.
