Static routes are for traffic that must not, or should not, go through the default gateway.
Routing is often handled by devices on the network dedicated to routing (although any device can be configured to perform routing).
For more information about firewalls, see the "Firewalls" section of the tab sets how users should be authenticated.
The default is to use local system authentication, meaning the users and their passwords are checked against local system accounts.
The Authentication Configuration Tool can also control some user settings that relate to security, such as creating home directories, setting password hash algorithms, and authorization.is the way that a user is identified and verified to a system.The authentication process requires presenting some sort of identity and credentials, like a user name and password.Along with allowing all of the identity and authentication configuration options that can be set through the UI, the authconfig --enableldap --enableldapauth --ldapserver=ldap://ldap.example.com:389,ldap://ldap2.example.com:389 --ldapbasedn="ou=people,dc=example,dc=com" --enableldaptls --ldaploadcacert=https://ca.server.example.com/ca --update .This automatically uses NIS authentication, unless the Kerberos parameters are explicitly set, so it uses Kerberos authentication (Section 18.104.22.168, “Configuring Kerberos Authentication”).Therefore, it is often not necessary to configure static routes on Red Hat Enterprise Linux servers or clients.Exceptions include traffic that must pass through an encrypted VPN tunnel or traffic that should take a specific route for reasons of cost or security.A Red Hat Enterprise Linux machine can also use external resources which contain the users and credentials, including LDAP, NIS, and Winbind.The Authentication Configuration Tool also configures settings related to authentication behavior, apart from the identity store.On Red Hat Enterprise Linux, the Authentication Configuration Tool has both GUI and command-line options to configure any user data stores.A local system can use a variety of different data stores for user information, including Lightweight Directory Access Protocol (LDAP), Network Information Service (NIS), and Winbind.
