🕒 Network Time Protocol (NTP) Service
Overview
The Network Time Protocol (NTP) service ensures that devices connected to the SNU campus network maintain accurate and synchronized system clocks. This is essential for time-sensitive operations, logging, security protocols, and coordination across systems.
Key Features
- Synchronizes device clocks with a known-good reference.
- Maintains high accuracy across the network.
- Supports NTP version 4, with backward compatibility for versions 1, 2, and 3.
- Available only within the SNU Campus Network.
SNU NTP Servers
The following servers are available for use within the campus:
| Step | Server Address | IP Address |
|---|---|---|
| 1 | ntp01.snu.edu.in
|
(IP to be added) |
| 2 | ntp02.snu.edu.in
|
(IP to be added) |
| 3 | ntp03.snu.edu.in
|
(IP to be added) |
💡 Note: These servers are accessible only from devices connected to the SNU campus network.
Setup Instructions
🖥️ Windows 10 / Windows 11
- Open Control Panel → Date and Time → Internet Time tab.
- Click Change settings.
- Enter one of the NTP server addresses (e.g.,
ntp01.snu.edu.in) and click Update now. - Click OK to save.
🐧 Linux
- Open terminal.
- Edit the NTP configuration file:
sudo nano /etc/ntp.confsudo nano /etc/ntp.confsudo nano /etc/ntp.conf - Add the server entries: server ntp01.snu.edu.in server ntp02.snu.edu.in server ntp03.snu.edu.in
- Restart the NTP service:
sudo nano /etc/ntp.confsudo systemctl restart ntpsudo nano /etc/ntp.conf
🍎 macOS
- Open System Settings → Date & Time.
- Unlock settings and enable Set date and time automatically.
- Enter one of the NTP server addresses (e.g.,
ntp01.snu.edu.in).
