This lab went fast and furious as you can tell by Brad's "fingers of fury" configuring the routers to connect to the switches to create the subnets. we all then had to connect and check the connections by pinging other classmates. Using special Cisco cables we were able to connect the three routers and on the final router connect to the switch with an rj45 crossover cable. The subnets were as follows:
1) 140.20.0.0
2) 140.20.32.0
3) 140.20.64.0
4) 140.20.96.0
Had a few problems at first but with some tweaking to some encapsulation by the Cisco Guru, all went pingingly well.
I set up PC VM 2007 on my laptop. Downloaded Damn Small Linux 4.4.10 in ISO format. Then went throught the process of creating a virtual machine. I did a VM a few years ago with DSL and it was really basic. It's improved a lot since. VM 2007 first created a configuration file, .vmc, then created virtual hard drive .vhd file. When I opened the vhd it told it to capture the DSL ISO file and hit enter. DSL started the boot process. I prefer to use ISO’s but you can run VM with an installation disk. Fortunately I’m running an old PIII 1GHZ laptop, so the newer version of DSL found (by found I mean had all the drivers) all the hardware just fine. It also found the old DLink wireless PCMCIA card I’m using for the internet. Surfed a bit on it. Sweet stuff. For whatever reason my prnt scrn wouldn’t do so, so I had to use another program from a USB suite called ASuite which has a lot of utilities you can use from your usb drive. Cool too. I was able to use the DSL OS just as if it were installed on the hard drive. DSL also has a feature to install it to a USB or hard drive. If you decide to do more virtual machines, I do recommend as much ram and processing power as possible, as the VM will use part of what you have, although in the settings for the VM you can adjust the memory it uses.

We started the tour on the 3rd floor, which has 2 equipment closets, major wiring there. You definately want a drop ceiling when running network cable. Cables come from the nodes to the patch panels in the equipment room. Labeling is important in the equipment room. The switches actually get you onto the network. The switches are smart switches which are Vlanned off logically. Some switches in the room were cisco 3548 and 3750 (PoE Power over Ethernet) which are 10/100 switches. There were also some FO switches connecting to multi-mode fiber cables running at a Gb instead of Mb. Video, voip and wireless access points are running thru this room as well as PoE for the same. The switches have to be PoE capable. PoE uses the wires that are not used for transmit/receive. Access layer switches are in this room and distribution layer switches are in the mix. Core switches 4006 are in use and 3510 is in the wings waiting to be installed. 3524PoE's are also used on the network. As well as switches and routers you also have battery backups to keep things running in case of an emergency. We also toured the grounds while walking over to Ken's office and saw where the cables were coming in from the road. Unfortunately, in the IT department itself it was impossible to tape the tour because of the noise so I didn't get any notes from that section of the tour and it was almost impossible to hear Ken. But here are some pictures from the 1st and 3rd floor Wayne West building and the IT Maintenance department. one of the photos is of the layout of the new vlan Ken was going to implement. Helps to work it out on paper or dry erase board.
We used a Dlink 615n wireless router and a Dlink wirless usb adapter to setup a wireless network. We cleared the settings on the router in order to get a fresh start with it. We installed the router software on one machine and the Dlink WUA 1340 usb adapter on another.I used the cd to install the adapter, but it caused a problem with Vista Ultimate, so it's a good idea to download the latest drivers from the website of your hardware. Once the router and adapter were installed we setup WPA encryption and connected to the internet. No sweat. First we setup the router IP then setup the IP pool. Then made sure the the other computer could connect with the router assigning it an IP address thru DHCP. Then, setup the PC with the wireless adapter a static IP address. This has to be outside of the DHCP pool or else you'll run into conflicts with the DHCP pool.
We first connected to the cisco switch, then worked on the subnets. Setup static ip addresses on the 4th subnet from the 160.20.o.0 network with a subnet mask of 255.255.240 which turned out to be160.20.48.0. Then we setup the network configuration on our systems using the local area connections properties. Setup static IP addresses and checked the connection to the switch and pinged one another as well as students thru the other switch.

Note: You will be blogging about your Wireshark lab. Take screen shots of the Wireshark output to include with your blog.Also you will need to research the Internet extensively to complete the assignment. Make use of the site http://www.ietf.org/rfc.html to find specific information about TCP, UDP, IP, Ethernet and ARP.
Start wireshark and view the packets that are being picked up by your computer.
1.Look at several packets and then complete the following :
a.Look at a packet that is using TCP and then answer the following:
Is this packet coming or going from your computer?
No, it is coming from my computer to 129.68.65.66.
iv.What is the Time To Live for this packet?
128
What does TTL mean?
Time to Live: maximum time that a datagram can remain on the network before it is discarded. Represents the number of times a datagram has been forwarded by a router also known as hops.
v.What is the Differentiated Services field?
Indicator to the router the level of precedence they should apply when processing the incoming packet.
List the current value.
0x00 (DSCP 0X00: Default; ECN:0x00)
What does this mean?
List 4 other possible values.
1. Default PHB—which is typically best-effort traffic
2. Expedited Forwarding (EF) PHB—dedicated to low-loss, low-latency traffic
3. Assured Forwarding (AF) PHB— which gives assurance of delivery under conditions
4.Class Selector PHBs—which are defined to maintain backward compatibility with the IP Precedence field.
vi.What is the protocol field set to?
TCP (0x06)
What does this mean?
The TCP protocol is the intended receiver of this datagram.
vii.What else did you see that was interesting about the IP packet?
Honestly, nothing.
viii.What is the framing type used?
The only “type” category I see is under Ethernet II and it is set to IP (0x800)
ix.What is the source and destination MAC addresses?
i.What is the destination MAC address? ff:ff:ff:ff:ff:ff
Why is this address used? Broadcast finding out what pc are connected.
ii.What is the source MAC address? 00:0e:08:e6:9f:fe
Why is this address used? It’s the MAC on my pc
iii.What is the destination IP address? 192.168.1.1
Why is this address used? It’s the address of the router.
iv.What is the source IP address? 192.168.1.104
Why is this address used? It’s my ip address.
v.Write a paragraph about anything else your learned from capturing an ARP frame.
ARP requests went out 17 times in the 30 minutes I started this capture. I thought it was odd that it had to be updated so frequently or so it seems. 192.168.1.1 is the router, but where is 192.186.1.100 coming from? I think the .100 is the start of the ip-pool. ARP is a short burst of information.
Wireshark can be handy to detect spyware and viruses, to track heavy network traffic to the source i.e. a worker using the work pc to look for movies while at work. It can expose a lot of information for diagnostics when you have a bad connection or some type of network interference such as EMI, or crosstalk when network cables have been improperly installed in a dropdown ceiling.
Following a packet is a nice feature along with following a connection thru the filtering. Wireshark can simplify troubleshooting by capturing all this information.
Create a host file mapping Blackboard to the IP address 10.10.1.81 Host files are a way of resolving domain names to IP addresses. In most OSes, the hosts file overrides and information that would be retrieved from a DNS server. You can use hosts file to you’re your network by setting up a test machine.
Because the computer no longer would have to ask the DNS server for the IP address, setting up your host file with frequently visited websites could potentially speed up your web surfing.
You can also check the hosts to see if spyware is infecting your system.
Lab - DHCP Setup a DHCP pool on the Dlink routers. Write a page about the lab in your blog. Include at least one screen shot of the Dlink web interface.
We set up a DLINK Router DHCP pool one day in class, but I think it was the day the port closed the bridge so I don’t remember doing this . Here are the steps to setup a the pool anyway.
Get into the router configuration. (unless you’ve changed the default password, you can use that)
You’ll want to go to, depending on the router, to the section that has DHCP settings
Change the starting IP address and type in the maximum # of users (on this router) on some you can tell the configuration what IP address is the last address you want to use.
Save the settings to the router.
Release and Renew your IP address and you should see the changes to you IP address take effect.
NOTE: Sometimes the routers require rebooting them, most of the time not.
TCP/IP Utilities Lab 1. Issue a Ipconfig command at the command prompt. Try some of the popular switches such as /all and /?.
With ipconfig you can check your ip address to ensure you are being assigned one from a DHCP server or that your static ip address is correct. You can also use /flushdns to remove all entries from the DNS name cache if you think it has been corrupted. /displaydns displays the contents of the DNS resolver cache. If you have multiple adapters connected you specify which adapter to release and renew.
Issue a Netstat command at the command prompt. Try some of the popular switches such as - p and -a. Capture a screen shot and write a paragraph about how you would use the command to troubleshoot a problem. Put this information in your blog.
Using netstat you can see which protocol might be eating up your bandwidth if your connection is slow. You can flush phantom connections that no longer need to be connected. Using the –b switch you can see what programs are associated with which connections.
Issue a Nbtstat command at the command prompt. Nbtstat is designed to help troubleshoot NetBIOS name resolution problems.
Displays NetBIOS over TCP/IP (NetBT) protocol statistics, NetBIOS name tables for both the local computer and remote computers, and the NetBIOS name cache. I do not have NetBios enabled on my network so the only things that show up are
Issue a Hostname command. You can change the computers host name thru this command.
Use the Nslookup command to view the IP address of at least three domain names.
Issue a Tracert command at home.
If you are running a web server, tracert can reveal lags in the routing if you try to access your site from another pc. Useful for troubleshooting internal networks by identifying where the problem occurs, i.e. a router, switch.
