1. SSH into Your OpenWrt Device

Open a terminal and SSH into your OpenWrt device:

ssh root@<your_openwrt_device_ip>

2. Verify NTP Configuration

Check the current NTP configuration:

uci show | grep ntp

3. Add NTP Servers to UCI Configuration

Add the NTP servers to the UCI system configuration:

uci add_list system.ntp.server='0.lede.pool.ntp.org'
uci add_list system.ntp.server='1.lede.pool.ntp.org'
uci add_list system.ntp.server='2.lede.pool.ntp.org'
uci add_list system.ntp.server='3.lede.pool.ntp.org'

4. Commit the Changes

Apply the changes to the configuration:

uci commit system

5. Restart the NTP Service

Restart the NTP service to apply the new configuration:

/etc/init.d/sysntpd restart

6. Verify Time Synchronization

Check the current date and time settings to ensure synchronization is working:

date

7. Ensure NTP Service Starts on Boot

Enable the NTP service to start on boot:

/etc/init.d/sysntpd enable

By following these steps, your OpenWrt device will be configured to use the specified NTP servers, and the system time will be synchronized correctly.

---

Manually Sync Time with an NTP Server

1. SSH into Your OpenWrt Device

Open a terminal and SSH into your OpenWrt device:

ssh root@<your_openwrt_device_ip>

2. Stop the NTP Service

Stop the NTP service to avoid conflicts:

/etc/init.d/sysntpd stop

3. Manually Sync Time with an NTP Server

Use the ntpd command to manually sync the time with an NTP server:

ntpd -q -p 0.lede.pool.ntp.org

The -q option tells ntpd to set the time and quit, and the -p option specifies the NTP server.

4. Start the NTP Service Again

Start the NTP service to resume automatic synchronization:

/etc/init.d/sysntpd start

5. Verify Time Synchronization

Check the current date and time to ensure it has been updated correctly:

date

By following these steps, you can manually sync the time on your OpenWrt device with a specific NTP server.

---

Troubleshooting “ntpd: bad address ‘0.lede.pool.ntp.org'”

1. Check DNS Configuration

Ensure your OpenWrt device can resolve domain names correctly:

ping google.com

If this fails, you might need to configure your DNS settings manually in the /etc/config/network file:

uci set network.wan.dns='8.8.8.8 8.8.4.4'
uci commit network
/etc/init.d/network restart

2. Verify NTP Package Installation

Ensure that the ntpd package is installed:

opkg update
opkg install ntpd

3. Manually Sync Time Using ntpd with IP Address

If DNS issues persist, use the IP address of the NTP server instead of the hostname:

ntpd -q -p 162.159.200.123

4. Ensure NTP Servers Are Correctly Configured in UCI

Check and reconfigure the NTP servers if necessary:

uci show system.ntp
uci delete system.ntp.server
uci add_list system.ntp.server='0.lede.pool.ntp.org'
uci add_list system.ntp.server='1.lede.pool.ntp.org'
uci add_list system.ntp.server='2.lede.pool.ntp.org'
uci add_list system.ntp.server='3.lede.pool.ntp.org'
uci commit system

5. Restart the NTP Service

Restart the NTP service to apply the changes:

/etc/init.d/sysntpd restart

By following these steps, you should be able to resolve the “ntpd: bad address ‘0.lede.pool.ntp.org'” error and ensure your OpenWrt device can correctly sync time with the NTP servers.

---

By following these organized steps, you should be able to configure, manually sync, and troubleshoot NTP settings on your OpenWrt device effectively.

• Objective: Identify any discrepancies between the actual state of the hardware and compliance requirements, noting outdated or non-compliant equipment.

7. Risk Assessment

• Objective: Assess the risks associated with identified compliance gaps, determining their potential impact and prioritizing them accordingly.

8. Remediation Plan

• Objective: Develop strategies to address identified compliance issues, which may involve hardware upgrades, additional maintenance, or new safety protocols.

9. Reporting

• Objective: Compile a detailed report summarizing the findings, risk assessments, and proposed remediation plans.

10. Submission and Review

• Objective: Submit the report to relevant authorities and hold review sessions with stakeholders to discuss the findings and next steps.

11. Implementation of Recommendations

• Objective: Execute the remediation plans to rectify compliance issues and ensure all hardware meets required standards.

12. Continuous Monitoring and Updates
