TANGO provides an access control (see The Tango controlled access system <access_control>)
TAC Configuration Tool:
Astor provides a tool to configure it. This tool is reserved to the TANGO administrator and needs a password to be opened.
Configure TAC by IP address and user:
User list is displayed in a tree under groups.
To configure you can Add/Remove a user and its group.
And define this user rights.
All Users:
Have only read access for all devices
User opid02
Has write access only for devices
fe/id/2
id/id/2
sys/hdb-push/*
and only for clients running on machines with IP address as xxx.yyy.22.*
Configure TAC for allowed commands:
The access control allows Write access or Read Only access. The Read Only access means:
Read only device attributes.
Cannot write device attributes.
Cannot execute commands (a command could be a write action).
Some commands could be a simple read action. For instance on Dserver class, the command QueryDevice does not write anything and returns the device list. This class is needed to establish a connection between a client and a device, and it is useful even if user is in read only access. This tool provide a list of allowed commands for a specified class. You can add or reove class by a right click menu.
