56 Chapter 3 Server Administration
To add a server to the Computers & Services list, click Add Server in the toolbar and
log in to the server. The next time you open Server Admin, any server you have
added is displayed in the list.
To limit the items that appear in the Computers & Services list, use the pop-up menu
above the list to select the items you want to see listed.
To change the order of servers in the list, drag a server to the new location in the list.
If a server in the list appears gray, double-click the server or click the Connect button
in the toolbar to log in again. Check the “Add to Keychain” option while you log in to
enable autoreconnect the next time you open Server Admin.
To remove a server from the Computers & Services list, select the server, choose
Server > Disconnect, and choose Server > Remove Server.
• You can control the level of security of communications between Server Admin and
remote servers by choosing Server Admin > Preferences.
By default, “Use secure connections (SSL)” is enabled, and all communications with
remote servers are encrypted using SSL. This option uses a self-signed 128-bit
certificate installed in /etc/servermgrd/ssl.crt/ when you install the server.
Communications use the HTTPS protocol (port 311). If this option is not enabled, the
HTTP protocol (port 687) is used and clear text is sent between Server Admin and the
remote server.
If you want a greater level of security, also select “Require valid digital signature”. This
option uses an SSL certificate installed on any remote server you want to manage
using Server Admin to ensure that the remote server is a valid server. Before enabling
this option, use the instructions in the web technologies administration guide for
generating a Certificate Signing Request (CSR), obtaining an SSL certificate from an
issuing authority, and installing the certificate on each remote server. Instead of
placing files in /etc/httpd/, place them in /etc/servermgrd/.
If you are interested in higher levels of SSL authentication, see the information at
www.modssl.org.
