'''This instructions apply to Debian 8 Jessie and Debian 9 Stretch. If you are running Angstrom check how to update at [[Radarcape:Linux_Distribution_choice]].'''

== SSH Login ==

=== Debian 8 ===

Default logins:
* user: Debian password: temppwd
* user: root password: <empty password>

=== Debian 9 ===

Default login:

* user: jetvision password: jetvision

For executing root/privileged tasks use sudo, eg. "sudo apt update -y && sudo apt upgrade -y".

== NTP ==

=== Debian 8 ===

By default includes systemd NTP Client Only. Check the status with:
<syntaxhighlight lang="bash" line='line'>systemctl status systemd-timesyncd</syntaxhighlight>

=== Debian 9 ===

Comes by default with [https://chrony.tuxfamily.org/ Chrony] configured as Client and Server, preferring the local GNSS/GPS reference if available.

As so it can work as a Stratum 1 Server, with a time accuracy at Ethernet level of about 1 μs.

==== [https://chrony.tuxfamily.org/ Chrony] configuration ====

Chrony comes installed and works by default without configuration on new devices.

If you have a older device with a GNSS chip which is not the Trimble SMT360 (Check under Status->GPS), then you need to edit file /etc/chrony/chrony.conf and increase refclock SOCK offset to 0.4.

To check status type:
<syntaxhighlight lang="bash" line='line'>
chronyc tracking
chronyc sources
</syntaxhighlight>

==== [http://www.ntp.org/ NTPD] configuration ====

NTPD support for the Radarcape is not the best.

If you prefer to run [http://www.ntp.org/ NTPD], then you can replace it.

First enable Radarcape to output data to NTPD. On the web menu go to Settings -> General -> NTP Reference Clock Data and activate "Publish time to shared memory for NTPD or Chrony".

Then on the console type:

<syntaxhighlight lang="bash" line='line'>
sudo apt update -y
sudo apt install ntp -y
</syntaxhighlight>

== Network ==

=== Debian 8 ===

=== Debian 9 ===
