Management

This guide explains how to troubleshoot management-related aspects of the Anapaya appliances.

Quick reference commands

Retrieve the current SCION configuration:

appliance-cli get config -f body.config.management

Time synchronization issue

Check the current date, timezone, and NTP status:

timedatectl status

The following output shows that NTP synchronization is not working:

                Local time: Mon 2023-10-30 12:39:43 UTC
            Universal time: Mon 2023-10-30 12:39:43 UTC
                RTC time: Mon 2023-10-30 12:39:43
                Time zone: Etc/UTC (UTC, +0000)
System clock synchronized: no
                NTP service: active
            RTC in local TZ: no

Time synchronization failure is usually caused by wrong NTP server configuration or unreachable NTP servers. NTP servers must be reachable via underlay IP connectivity. See System for details on how to configure time servers.

Temporary fix

Set the time manually as a temporary measure:

timedatectl set-time '2015-11-20 16:14:50'

Configure NTP servers and ensure they are reachable to avoid recurrence.

Time zone not needed

It is not necessary to configure a timezone for the SCION network to be operational. If you prefer, you can set the timezone using:

timedatectl set-timezone UTC

We recommend using UTC everywhere since it makes it easier to correlate events across timezones.
