Case Project 5-1 You work at a help desk and have just received a call from an employee who says she can’t access network resources. You want the employee to view her IP address configuration. Write an e-mail to the employee, explaining what command-line program to use and how she can use it to find the information you need. After following your instructions, the employee tells you that her IP address is 169.254.14.11 with the subnet mask 255.255.0.0. What conclusion can you make from this information?
Please open a command prompt via
windows key + r
and then type
and press enter, then type
and press enter. What you will look for is the line that says ‘ipv4 address.’ Can you tell me what that line says?
Also, a 169.254 address means her computer can’t see the network. I’d recommend running ‘netsh winsock reset’ via command line, and restarting the computer. Typically just as fast as ipconfig release and ipconfig renew and fixes more problems. If that doesn’t work I’d check to make sure that the network config isn’t set to a specific ip, subnet, or dns manually and is instead using dhcp (as it probably should be).
Case Project 5-2 You have configured a LAN with 25 workstations, three network printers, and two servers. The workstations and printers will have dynamically assigned IP addresses, and the printers always need to have the same IP address assigned. The servers will have static IP addresses. What should you install on one of the servers, and what are some of the configuration options?
What I should ‘install on one of the servers’ is impossible to answer definitively because we’re not given the hardware/software configurations of those servers or their physical locations or how they connect to the network or what security concerns there are. I would set up a dhcp range of 192.168.1.2-100 and then anything after 101-253 can be manually set up on a server, printer, or some other device that requires a static ip. Any server’s operating system is likely to already have network software pre-installed to be able to handle manually setting the ip, subnet, and dns. I would recommend setting up ssh and/or http(s) as well (or rdp in the case of a windows server) to be able to access the servers remotely. For example, my mediawiki installation at home it’s accessible via http or I can access the server itself via ssh.
