I’m intend to set up my own BIND9 Domain Name Server (DNS) service but I’m getting an error – “Errors were detected”. How Do I prepare BIND9 to work with Go Daddy domains and fix this issue?
How do I change or set my hostname ( computer name ) under OpenBSD operating system?
Q. How do I find out which service is listening on a specific port? How do I find out what program is listening on a specific TCP Port?

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.
