• History of Linux and UNIX
  History of Linux and UNIX are intertwined. Way back in 1957, Bell Labs of AT&T felt the need for an operating system. Thus was born BESYS. Eight years later, in collaboration with MIT and GE, AT&T developed another operating system known as MULTICS. MULTICS had lots of problems, so, in 1970, Ken Thompson, Dennis Ritchie, M.D. McElroy, and J.F. Ossanna developed Unics which stood for Uniplexed information and Computing Service.

• Understanding How Linux /proc Filesystem Works
  There are two Linux file systems that always confuse Linux users. These two directories are /proc and /dev. These two directories do not have any Windows counterpart and are not at first glance easily understandable. We can define /proc file system as a real time, memory resident file system that tracks the processes running on your machine and the state of your system.

• Active Directory NTP Requirements
  In Linux the NTP program is configured using either the /etc/ntp.conf or /etc/xntp.conf file. The NTP server uses UDP packets to query time servers on port 123. Depending on your Linux configuration, the initscripts for the ntpd service may have iptables commands to allow ntpd to access the external time servers.
