Welcome to Unified Networking

                                      IP SUBNETTING General way of sub-netting: In this way we will be using two different formulas for calculating sub-networks and Hosts. Calculating Subnets: Example 1: IP: 172.16.0.1/18                                             X.X.11000000.00000000 Formula for calculating subnetworks is 2^n  (2 to the power of n). n = The number of bits used for Networks. Note: as the first two octets 8+8 = 16 bits have been filled completely we should not consider them. The remaining two bits only we should consider for calculating subnetworks. Hence,  n= 2. Number of subnets is = 2^2 = 4 4 subnets. They are: 172.16.0.0/18      -  172.16.63.0/18 172.16.0.64/18    - ...

                     OTRS INSTALLATION STEP BY STEP OTRS:   OTRS , an  initial-ism  for O pen-source T icket R equest S ystem, is a free and open-source trouble ticket system software package that a company, organization, or other entity can use to assign tickets to incoming queries and track further communications about them.   Key features: Adding a note to the logged ticket. Assigning/modifying priority for your logged ticket. Escalating tickets. Statistics of the tool. Excellent GUI     INSTALLATION STEP BY STEP:              Operating system  :  Oracle linux (recommended due to its less dependencies)             IP ADDRESS          :    192.168.247.131       SERVER NAME     :   server.root.local ...
