Info

Enabling and disabling servers Server Name Notes routed The server used in conjunction with RIP routing. See Appendix D. sendmail The SMTP server. See Chapter 11. shund The shund server accepts shunning requests from Intrusion Detection Servers (IDS), and verifies the signature on the data that the IDS has generated. snmpd Simple Network Management Protocol daemon. The SNMP server can only be enabled for one burb, and it cannot be enabled for the Internet burb. See Chapter 14. spamfilter This server allows you to enable anti-spam mail filtering for the burbs that you specify, as well as configure whitelists for internal and external burbs. For information on configuring antispam mail filter rules, see “Creating Mail Application Defenses” on page 6-21. For information on configuring advanced spamfilter properties and whitelist configuration, see “Configuring advanced anti-spam options” on page 11-13. sshd The Secure Shell daemon server. The SSHd server provides secure encrypted communication between two hosts. See Chapter 2. sso The Single Sign-On (SSO) server allows you to configure SSO. SSO allows users access to multiple services with a single successful authentication to the Sidewinder G2. See “Configuring SSO” on page 9-27. Note: If you disable the SSO server, the SSO authenticated user cache will be emptied (that is, all cached users will be removed). When the SSO server is enabled again, all users will need to authenticate before being added back into the cache. synchronization The synchronization server is used to synchronize configuration information among Sidewinder G2s that are participating in a One-To-Many cluster or an HA cluster. It also allows you to perform a configuration backup or restore to/from a remote Sidewinder G2. See “Configuring the synchronization server” on page 3-33. telnet If you disable the Telnet server, all future connections will be denied. Any users who are currently logged in to the server will not be affected. See Chapter 2. upsd The Uninterruptible Power Supply daemon server. See “Configuring the Sidewinder G2 to use a UPS” on page 3-58 for more information. WebProxy The Web Proxy server. Certain Sidewinder G2 features such as SmartFilter will not work if the Web Proxy server is disabled. See Chapter 12. 3-32 General System Tasks
Configuring the synchronization server Figure 3-13. Synchronization server: Configuration tab About the synchronization server Configuration tab Configuring the synchronization server The synchronization server is used to synchronize configuration information among Sidewinder G2s that are participating in a One-To- Many cluster or an HA cluster. It also allows you to perform a configuration backup or restore to/from a remote Sidewinder G2. To configure the synchronization server, log in to the Admin Console, select Services Configuration -> Servers and then select synchronization from the Server Name list. The synchronization server Control tab appears. To enable or disable a server, select the Control check box for that server for each burb. (A check mark appears for each burb in which the server is enabled.) To configure the synchronization server, select the Configuration tab. The following window appears. This tab allows you to configure the shared synchronization key and port number, and allows you to select the SSL certificate for the synchronization server. Follow the steps below. Note: The synchronization server is automatically configured for you when you create a High Availability or One-To-Many cluster. 1. In the Shared Sync Key field, type the shared key. The shared key is any 10 character, alphanumeric string (for example, 12345abcde). You will need to enter this key again if you configure HA or One-To-Many, or if you perform a configuration backup or restore from a remote Sidewinder G2. 2. In the Port field, specify the port on which the synchronization server will listen. The default is 9005 and should not be changed. 3. In the SSL Certificate drop-down list, select the certificate to use for the synchronization server. The certificate will be one of the following: the default certificate a self-signed, RSA certificate that is defined on the Firewall Certificates tab of the Certificate Management window. Important: Before assigning a new certificate, you must first create a new certificate. General System Tasks 3-33
