The Aveksa Compliance Manager is already configured to synchronize its system clock with a public time server, clock.psu.edu. It uses a script named, updatetime in the folder named, /etc/cron.daily uses the rdate command to update the system clock’s time with the time from the time server.
However, most corporations block public time servers and don’t allow the rdate command with the corporate internal time servers. As a result the ntpdate is used with the corporation’s internal time server.
Steps to Synchronize the ACM system clock with the Corporate Time Servers
1. Obtain the hostnames or IP addresses for the corporate internal time servers
2. Login to the ACM GUI
3. Select the Admin Tab
4. Select the Appliance Tab
5. Select the Edit button
6. Enter the corporate internal time server hostname or IP address
7. Select the OK button
This will change the script named, updatetime in the folder named, /etc/cron.daily. It will replace the public time server, clock.psu.edu with the corporate internal time server hostname or IP address in the file.
8. Use a secure shell, like Putty to login to the ACM system
9. As the root user edit the file, /etc/cron.daily/updatetimeto use the rtpdate command instead of the instead of the rdate command. Comment out the rdate command in the file. Put the pound character, # in front of the rdate command to comment it out, as shown in the example. Add the ntpdate command in the file.
10. An example file is shown below.
#rdate -s 220.127.116.11
ntpdate 18.104.22.168 22.214.171.124 126.96.36.199
11. To test the file changes, execute it from the command line
