🕒 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
|
10.3.36.242 |
| 2 | ntp02.snu.edu.in
|
10.3.36.243 |
| 3 | ntp03.snu.edu.in
|
10.3.36.243 |
💡 Note: These servers are accessible only from devices connected to the SNU campus network.
