Note: This document refers to the server's own settings as a network client, not to the configuration of any proxy service the server may offer to its clients.
Symptom
Settings formerly in the Proxies section of the Network preference pane are missing after an upgrade to Mac OS X Server 10.2 or later.
Solution
If you have already upgraded, you will have to manually re-enter the proxy information.
If you have not yet upgraded and have enough proxy settings to justify using a workaround, you may follow these steps to save and reload them after the upgrade:
1. Log in to the Server as root. See technical document 106290, "Mac OS X: About the root User and How to Enable It".
2. Open the Terminal (/Applications/Utilities/).
3. Type: cd /var/db/SystemConfiguration/
4. Press Return.
5. Type: cp preferences.xml preferences.xml.BeforeUpdate
Note: When you upgrade the system, the proxy settings will still be overwritten; but you just saved a copy in this step.
6. Upgrade to version 10.2, and complete the Server Assistant.
7. Log in to the server as root.
8. Repeat Steps 2 through 4.
9. Type: cp preferences.xml.BeforeUpdate preferences.xml
10. Restart the computer.
When the system is restarted, the proxy information you had prior to the upgrade should be preserved.
