Free TACACS+ Servers

TACACS+ provides authentication, authorization, and accounting services for network devices. In simple terms this provides granular control over who has access (authentication), what that user is allowed to do (authorization) and keeps a log (accounting) of everything that user does.

Marc Huber has created and maintained a fantastic open source TACACS+ server for Linux available here: http://www.pro-bono-publico.de/projects/tac_plus.html

If you’re more inclined to the Windows world have a look here at a free TACACS+ server for Windows: http://www.tacacs.net

Caller ID Testing

In this age of cell phones with caller ID (ANI) displays it’s easy to forget that there was a time when this feature didn’t exist.

If you’ve ever been in a situation where you need to learn what the caller ID is you can simply dial either of these numbers to have the caller ID read back.
