If you are like me you might have had trouble setting up NTP on your Netscaler. I finally was able to get it working and wanted to give everyone the steps.
1. Set the timezone on your NetScaler.
a. Log in via CLI (Use putty, hyperterminal cannot render the screen correctly)
b. Run configns
c. Select the options to set your appropriate timezone
2. Decide what NTP server you are going to use. Either use a Domain Controller or choose one of the free ones available online.
3. Test that you can successfully connect to the NTP server
a. Drop into the SHELL
b. type "ps axfu | grep ntp"
c. type "kill <Process Number>" on any NTP processes currently running
d. type ntpdate <IP of NTP server>
At this point your Netscaler will connect to the NTP server if it can and adjust it's time. If it does not verify there are no firewall rules or other devices that could be blocking communication. Try another NTP server as well to make sure it's not an issue with the individual server.
4. Setup your NetScaler to automatically adjust the time
a. Drop into the SHELL
b. CD to the /etc directory
c. Use vi to open ntp.conf
d. Uncomment the line server 1.1.1.1 burst and replace 1.1.1.1 with the IP of the NTP server you are going to use
e. Comment the line restrict 172.0.0.1 mask 255.255.255.255
d. Add the restrict ip line to the end making sure it uses the same IP as NTP server you are using.
Your file should now look like this if 22.22.22.22 was your NTP server
server 22.22.22.22 burst
restrict default ignore
#restrict 127.0.0.1 mask 255.255.255.255
#corresponds to 'server' entry above
restrict 22.22.22.22 mask 255.255.255.255
5. Copy the file over to your /nsconfig directory
6. Open your /nsconfig rc.conf file to include the following entry (Allows NTP daemon to start on reboots)
a. ntpd_enable="YES"
7. Start your daemon without rebooting
a. Run the following command in the shell "/usr/sbin/ntpd -c /nsconfig/ntp.conf -l /var/log/ntpd.log &"
Hopefully this helps everyone out.
