OTW discusses new vulnerabilities and issues with devices found in millions of companies around the world.
OTW loves the Mr Robot TV Series as a lot of them are actually realistic - unlike a lot of other shows.

This is one of multiple GNS3 labs videos. This video shows you Wireshark captures of both PAP and CHAP negotiation.
#CCNA #CCENT #CCNP
===========================================
Tasks:
===========================================
1) Enable PPP between R1 and R2
2) Enable two-way PPP PAP authentication between R1 and R3 (R1 password = cisco1, R3 password = cisco3)
3) View debug commands to view the PPP negotiation
4) View debug commands to view only the authentication process
5) Use show commands to prove the PPP PAP has successfully negotiated
6) Enable two-way PPP CHAP authentication between R1 and R4 using a password of cisco
7) View debug commands to view the PPP negotiation
8) View debug commands to view only the authentication process
9) Use show commands to prove the PPP CHAP has successfully negotiated
10) Use Wireshark to view to the PAP and CHAP negotiation
- What options does LCP negotiate?
- Does PAP use clear text authentication? Can you prove it?
- Which hashing algorithm used by CHAP?
- Does CHAP hash passwords?
- Can you see the IPCP NCP negotiation?
11) Enable EIGRP in AS 100 and prove that all devices can ping each other.

QoS is the measure of transmission quality and service availability of a network (or internetworks).
Service availability is a crucial foundation element of QoS. The network infrastructure must be designed to be highly available before you can successfully implement QoS. The target for High Availability is 99.999 % uptime, with only five minutes of downtime permitted per year. The transmission quality of the network is determined by the following factors:
•Loss—A relative measure of the number of packets that were not received compared to the total number of packets transmitted. Loss is typically a function of availability. If the network is Highly Available, then loss during periods of non-congestion would be essentially zero. During periods of congestion, however, QoS mechanisms can determine which packets are more suitable to be selectively dropped to alleviate the congestion.
•Delay—The finite amount of time it takes a packet to reach the receiving endpoint after being transmitted from the sending endpoint. In the case of voice, this is the amount of time it takes for a sound to travel from the speaker’s mouth to a listener’s ear.
•Delay variation (Jitter)—The difference in the end-to-end delay between packets. For example, if one packet requires 100 ms to traverse the network from the source endpoint to the destination endpoint and the following packet requires 125 ms to make the same trip, then the delay variation is 25 ms.
Each end station in a Voice over IP (VoIP) or Video over IP conversation uses a jitter buffer to smooth out changes in the arrival times of voice data packets. Although jitter buffers are dynamic and adaptive, they may not be able to compensate for instantaneous changes in arrival times of packets. This can lead to jitter buffer over-runs and under-runs, both of which result in an audible degradation of call quality.
Translation:
In packet tracer, I’m going to start simulation mode and then on PC 1, I’m going to open up a web browser and go to Cisco.com.
Now the first thing that PC needs to do is determine the IP address of Cisco.com.
So it’s going to send out a DNS request message for Cisco.com. So scrolling down here notice we’ve got a DNS query for Cisco.com. Capture forward; that gets sent to the router. When it gets sent across the serial link, notice the D

This is a DHCP Lab.
Labs! Labs! And more Labs! Get the hands on experience to pass your CCNA exam!
Make sure you are ready to pass the CCNA exam! Prepare practically for the Cisco CCNA certification which is the most in-demand networking certification in the world today! Make sure you can pass the Cisco CCNA Routing and Switch 200-125 exam!
This course tests your knowledge of CCNA topics with practical, hands on labs. Labs include both configuration as well as troubleshooting labs.
Ask yourself these questions:
- Are you ready and prepared for the labs in the CCNA exam?
- Are you able to troubleshoot Cisco networks?
- Are you confident with your ability to configure networks as required by Cisco to pass the CCNA?
Answer:
This course helps you prepare for the exam and gain the confidence to pass the exam!
There are many topologies and many labs in this course!
Transcription:
So here’s Router 1 sh ip int brief shows us the IP addresses configured on the router.
Here’s the loopback interface, here’s the IP address on gigabit is 0/0/0
So the first thing we need to do is configure an exclusion range
So ip dhcp excluded-address 10.1.1.1 to 10.1.1.100
The next thing we need to do is configure a DHCP pool called PC. The network to use is 10.1.1.0 with a subnet mask of /24 with I need to configure a default router or default gateway of 10.1.1.1.254 because that’s the IP address of Router 1. So the default route will be that. DNS server will be the router and that looks good.
So show run there is our exclusion range and there’s our DHCP poll show ip dhcp binding. Our plant has already been allocated an IP address 10.1.1.101 so let’s confirm that by opening up a command prompt. IP config, there’s the IP address of the PC, there’s the subnet mask, there’s the default gateway.
Can the PC ping Router1? Yes it can. Can it ping the loopback of Router 1? Yes it can.
And to confirm that, sh ip int brief there’s the loopback of Router 1 and the PC can ping the loopback of Router 1.
Can the router ping the PC? Yes it can. We’ve successfully configured a DHCP on Router 1 and tested that the PC gets an IP address via DHCP and that the PC can ping the loopback of Router 1.
That was a very basic DHCP lab. In the next lab, it gets more complicated.
