Tacacs+ And Radius Server Configuration; Tacacs+ Server Installation And Configuration - Safran WR-Z16 User Manual

APPENDIX
The magnitude that was measured in the unit's testing setup is additive phase
noise. We have not measured the noise of the external reference, but only the
noise that is linearly added by the WR-Z16 as the 10 MHz time signal is consumed
and regenerated. For more information on your unit's documented jitter per-
formance, see the product data sheet.

TACACS+ server installation and configuration

In order to install TACACS+ on a server with Ubuntu 18.04, it is possible to use
APT to install version 4.0.4 of the package tacacs+ by using the following com-
mand:
apt-get install tacacs+
After this, it can be verified if the service is running by using the command:
service tacacs_plus status
The first step to configure the server will be opening the port 49 with TCP:
#ufw allow 49/tcp

reference. Typically, minimum warmup time is 10 minutes in office con-
ditions. This could take longer in colder environments.
Unused fiber network interfaces that have not been explicitly turned off
may add a certain amount of noise. If a user is concerned with achieving the
lowest possible phase noise, it is desirable to keep unused interfaces com-
pletely shut down (writing the command 'ifconfig wrX down' in the device
shell for each X unused interface). This can be reverted by simply writing
the command 'ifconfig wrX up'. This is not the most user-friendly approach
because it requires access to the device shell, and because this con-
figuration is lost upon reboot.
For the same reason stated right before, a user should not mix LJ and non-
LJ devices in the same setup (or, if he/she wants to do so, he/she should be
aware that the devices derived from it will have higher phase noise).
