TACTest is a free utility that is used for testing TACACS+ servers. It will print out request and response information, and can be used for performance testing. This tool is very helpful when testing, debugging, and qualifying TACACS+ servers. TACTest can be scripted and can log results to a text file.
TACTest is an independent utility that can be run in standalone mode without requiring TACACS.net or any other TACACS+ server to be running on the same computer. It can be used to test any server that runs the TACACS+ protocol. TACTest is included with the server installation wizard and is installed by default with the TACACS.net TACACS+ server. TACTest can be installed without the TACACS.net TACACS+ Server if this option is chosen when running the installation wizard.
TACTest is free software. It can be downloaded and used without requiring registration.
IMPORTANT NOTE: In order for TACTest to work, the system running the utility must be added to the TACACS+ server’s authorized clients list. In TACACS.net, localhost (127.0.0.1) and RFC 1918 IP Addresses are added by default to the clients configuration.
After the software has been downloaded and installed, it is run from the command line. The Command Prompt can be found in the Start Menu under Accessories. After you have launched the Command Prompt, you will see the prompt C:\> on most computers. This is where you enter your commands.
