• I did research what is happen in the SRA server. Here what I found:

• http://askubuntu.com/questions/230698/how-to-restart-the-networking-service
  -----This will reset the network manager (service network-manager restart). Make sure they are active and correct IP address after checking the processor, hard drive space, ssh status, sshd status, and ifconfig. 
• https://www.blackmoreops.com/2015/03/26/setup-dhcp-or-static-ip-address-from-command-line-in-linux/                                                                                                                                     -----This setup the static IP address if needed.
• Crontab linux might solve the issue but please make sure to ask your supervisor to approve.

• If the ssh server keeps going down, make sure to update kali linux and ssh. Since it is not connected to the internet, plug it in where you can access to internet temporarily and update everything. Then vim the sshd_config and configure. After that service ssh restart and check the ssh status.
• plug to the ethernet
• go to setting, Network in particular.

Important lessons learned/New Skills

Steps to check for server
Linux command line on left

1. Check for resources
• top --- shows RAM
• df --- is the filesystem
• df -h --- Hard drive space, h is human readable 
• ps -ef --- show all the Processor 
2. Networking
• netstat -an | grep 5902 --- Check if the port is listening
• service ssh status --- Check for ssh status if is running
• service ssh start --- start the ssh 
• service ssh restart --- restart the ssh (Restart system if need)

--ifconfig Display information about all the network interface currently in operation. This can also change the IP address by ifconfig then the interface eth0 then numerical numbers. Example ifconfig eth0 1500 this will change IP address.

--who This show who is online at that time

--last history of who login

--history display the history of a particular user to find activities.

Issues/ Concerns 

Students are able to change the IP address by using the command like ifconfig OR they might change it accidently.
