Using system tools – Whowatch

While keeping a watch on the network, an administrator would also want to keep a watch on users who are currently logged on to the system and also check what each user is doing on the machine.

Whowatch is the perfect tool for all these tasks. It uses a simple text-based interface, which is easy to use and can display information about a username, user process, and also the type of connection being used, such as SSH and telnet.

Since Whowatch doesn't come as a preinstalled package in Linux, we have to install it to use it. The command to install Whowatch is as follows:

apt-get install whowatch
