Q. How do I Monitor Linux User Activity in real time?
A. The whowatch program scans the most current common log file of Linux server and creates the following statistics in real time:
=> The users currently logged on to the machine, in real-time.
=> User login name,
=> User tty
=> User host name
=> User’s process
=> The type of the connection (ie. telnet or ssh)
=> Display of users command line can be switch to tty idle time.
=> Certain user can be selected and his processes tree may be viewed as well as tree of all system processes.
=> Kill user process etc
I have already written how to install and configure whowatch. Please refer this previous article.

A. Telnet is an insecure service. It is recommended that you use ssh service. However sometime telnet server or service is needed. Here are instructions to enable telnet:
Install telnetd server
$ sudo apt-get install telnetd
Restart inetd service:
$ sudo /etc/init.d/openbsd-inetd restart
You should now be able to telnet to the server from Windows or Linux desktop system to Ubentu Linux telnet server. Type the following command to connect to Telnet server:
$ telnet ubentu-linux-server-ip
$ telnet 192.168.1.200
