About Vazhai  : Vazhai is an NGO established in 2004 working on mentoring underprivileged kids from Dharmapuri(Bangalore wing of Vazhai) and Vizhupuram(Chennai wing of Vazhai) districts where due to social and political reasons literacy rate is very low. It was formed by Presidency college graduates under the  guidance of experts like  writer Gnani ( https://en.wikipedia.org/wiki/Gnani_Sankaran ). Vazhai does get some financial aid from The Agaram foundation. Vazhai’s main motive is to raise the children to be  a socially responsible person and to groom them so that he/she gets to lead a dignified life in the society .

But these do NOT feature as a priority in Vazhai’s agenda. Infact they provide very minimal financial aid to the students. Vazhai works like this : ·     ...

Everything goes fine till when did shut down the server and launch the same server ( same hostname ) with different hardware due to Memory problem. Note : Memory problem - Sometimes, We need better RAM and Harddisk to handle the traffic when server started to get more request from the Client.  In this moment, the icinga custom scripts and inbuild scripts that related to the server hostname are started to throw the error message that can't connect to server using SSH : SSH Failed ( Same host name.

But, My monitoring server was trying to connect to New Server with Old server SSH Key from Known_Hosts. To avoid this problem, We need to remove Old Server SSH Key belong with Hostname from Known_Hosts...
