The arp and getmac commands are two windows commands that are not included in all editions of windows. They deal primarily with mac addresses. They can be used to find out information about your network card and other network cards on the network. They have limited use, but it's important to know all the tools at your disposal.

Telnet and SSH: Capturing and examining tips | http://www.pluralsight.com/courses/wireshark-introduction In this video, Pluralsight author Ross Bagurdes shows you how to capture and examine Telnet and SSH in Clear Text. In the full course, we walk through the basics of Wireshark. Because Wireshark only captures what it sees on the network, we will also describe common protocols, and examine their operation using Wireshark captures. Wireshark is an amazing utility designed to give network engineers the ability to see into network communications in real time. Since it is a community-supported application, it is free to users! In this series, we walk through all of the basics you need to get yourself familiar with what Wireshark is doing, as well as how you can use Wireshark to examine the operation of network protocols. First, we examine what Wireshark is doing during a packet capture, and then we move into some of the options available to capture traffic, including capturing traffic on more than one interface, as well as using the command line interface on systems to capture traffic. Next, since Wireshark parses out the headers of each piece of data it captures, you're able to examine the header at each layer of communication. In this series, we take a look at ARP, ICMP(used for Ping), TCP, HTTP, DNS, Telnet, and SSH.

I try to give a simple explanation about how to read a routing table and the different pieces of information found on it. In this demo, I use only classful IPv4 addresses without subnetting. Each IPv4 network address is a level 1 and at the same time an ultimate route.; The targeted audience is for CCNA students and any students willing to start learning about routing.

Hunting For Devices With ARP's And Wireshark It always gives me sense of satisfaction when I have a challenge and can leverage some knowledge to figure out. Today I was in the lab and was powering on two Cisco switches when I noticed that they weren't labeled with their IP addresses. I'm not sure why I did not label them, but now I have to pay for it. For those of you who have not been in this situation before I will explain. My switches have a DB9 serial connection and of course good luck finding a computer with a serial port. So now I have to rummage through the box of wires to find the serial to USB adapter. I have had to buy a second one in 2 years since my original does not have a Windows 7 driver, but I digress. After I find the cable, I have to find the installation disk because last week I migrated to a new laptop.... I'm sure you get the picture. On to plan B. I know the switches have IP addresses since I hard code IP addresses on all of my switches. Now here's where a bit of knowledge comes in. I know that when a device powers up and either obtains an IP addresses via DHCP/BOOTP or statically has an IP assigned it will send out a specific ARP called a gratuitous ARP. Perfect, now all I have to do is make sure the switch port is connected to my subnet, start any protocol analyzer (I chose Wireshark) and power up the switches. In this video I show you how to find the Gratuitous ARP quickly, create a display filter and lastly, locate the 2 switches' IP addresses. Enjoy

https://nwl.cl/2xthPQM - ARP (Address Resolution Protocol) is used on Ethernet (LAN) to find the MAC address of another host. When a host on the network doesn't know the MAC address of the device it wants to reach, it will broadcast an ARP request. All hosts on the segment will receive this ARP request and one of them will respond with an ARP reply. In this ARP reply, you will find the IP address and MAC address of the destination host. Once the host that sent the ARP requests receives this information, it will be able to reach the destination.

Bro is the most powerful network visibility solution for information security professionals, but it remains a tool that is not widely understood in the enterprise market. This webinar will explain the power of Bro, where it fits in the security landscape, how it complements other security tools, and how it helps incident responders do their jobs more quickly and effectively. Bro had early adoption in the defense, intelligence and other government agencies, as well as in research & education, but only recently has its use in the enterprise market expanded. Bro is very powerful but can be difficult to implement, use, and integrate. Today, as the threats facing enterprises get more sophisticated and destructive, and as networks get more complex and heterogeneous, the power of Bro's rich data has become vitally important. Corelight was founded in 2015 by the creators and maintainers of Bro, including Vern Paxson who created it at Lawrence Berkeley National Lab in 1995, to provide an enterprise-class solution built on Bro for enterprise customers. Matt Bromiley, is a SANS Digital Forensics and Incident Response instructor and a GIAC Advisory Board member. He is also a senior managing consultant at a major incident response and forensic analysis company, bringing together experience in digital forensics, incident response/triage and log analytics. His skills include disk, database, memory and network forensics, as well as network security monitoring. Matt has worked with clients of all types and sizes, from multinational conglomerates to small, regional shops. He is passionate about learning, teaching and working on open source tools. Seth Hall is a co-founder and Chief Evangelist at Corelight in addition to being a core team member on the Bro project. He is also a connoisseur of stories about how intruders were caught in the act and devising new mechanisms to catch even more intruders. In a past life he lived and breathed incident response in Higher-Ed at The Ohio State University.

Originally recorded September 12, 2017 This talk aims to help those new to Bro get more familiar with its core concepts and gain a better understanding of the various ways it can be used. Many of those working in the cybersecurity field have little to no software development background when they are introduced to Bro. Many can immediately recognize the forensic and network defense value Bro’s network traffic logs provide, but learning the programming language can seem like a daunting task. Unfortunately, a sound understanding of the Bro programming language and how it can be used to interact with captured network traffic is necessary to begin to realize Bro’s full potential. This talk seeks to provide attendees with some of the foundational knowledge and understanding that can help get up to speed quickly with the language. Functional code samples, with direct applications for practitioners will be used to illustrate core Bro language concepts, scripting tasks common to network monitoring and some helpful scripting techniques that leverage built-in functionality. Emphasis will be on real-world scenarios that new Bro users can apply to support their own monitoring objectives and all code will be made available for download (or referenced) after the presentation.

Welcome back to part 3 of our 5-part video series on examining personal boundaries versus conditions of love. In today's video we are going to explore 4 types emotional boundaries and then we are going to do a fun exercise. So, let’s dive in! *************** Emotions should not be ignored, nor placed in charge. Emotions are very important because they are like giant road signs pointing you towards the solution of whatever struggle you may be facing. And they are also the path to living a fulfilling life in love, and partnership. When we think about emotional boundaries, probably the first word that comes to mind is “neediness”. Individuals with insecure attachment styles have a very particular relationship to this idea of “neediness,” and that includes individuals that are... More anxiously clinging--whom I refer to as Open hearts, Avoidant of closeness and intimacy--whom I refer to as Rolling Stones Or experience an intense internal conflict over being both anxiously desirous of, and fearfully avoidant of, closeness and intimacy, --whom I refer to as Spice of Lifers. We need our relationships for nurturing and for emotional well-being. We need to feel connected, valued, cared for, and respected. These needs do not exist in a vacuum. They exist in relationship to one another. So, how do we identify our emotional boundaries, and where we might want to strengthen them? In today's video we are going to explore 4 types emotional boundaries and then we are going to do a fun exercise. I have organized each type of emotional boundary into a kind of archetype or character, so that it's easier to conceptualize. And those are... ⭐Assimilators-People pleasers that desire belongingness, and bend over backwards for it. ⭐Guards-Help everyone else and don’t know how to ask for help, or let love in. ⭐Dictators-Need to control everyone and everything out of a fear of annihilation. ⭐Rescuers- Try to love the “bad” part of themselves by rescuing “bad” partners. Watch the video to find out more, and make sure you stick around until the end so you can participate in the experiential art activity to help you integrate all that you have learned! ******** Other videos in the series...

Learning about 4 different styles of loving--”attachment styles”--can help you decipher the secret code to attracting the love you want. Now, When most people come to me, they are usually nose-deep in the anxious-avoidant trap, and start out with the question, “How can I make THIS work?” But the real question is, “How can I take command of my emotional life and stand so sovereignty within myself, that I can find the passionate, soul-shaking love that I want, no matter my circumstances?” And, as you can imagine, it’s a question far too big to address on a Facebook post!

Simply Rhino’s senior trainer, Phil Cook, has created a series of videos examining the creation of a styling model for an engine cover that will ultimately be exported into SolidWorks. In this video, the second in the series, Phil examines adding local detail to the engine cover model created previously. In modelling the air duct detail there are two main considerations. First, it’s important to create a seamless transition between the main surface and the lead in to the duct and second it’s important to control the edge blends so that they transition between a relatively straightforward corner blend to run out completely into the main engine cover surface. These are both common situations in 3D surface modelling even though the specific context might be different. With the duct detail completed, Phil looks at creating the centre blend to join the two symmetrical engine cover halves before checking that the geometry is optimised for exporting.

Originally recorded September 13, 2017 In this presentation, we demonstrate how Bro can be used to successfully detect malicious traffic from compromised machines to a remote command and control (C2) server. Specifically, our team focused on detecting Cobalt Strike, a popular penetration tool. Cobalt Strike possesses a sophisticated callback mechanism that uses common protocols to beacon back to a remote C2 server and fetch instructions. From the remote server, attackers can send C2 instructions to processes running on the compromised hosts. This stored-and-forward architecture is designed to avoid detection, blending in with ordinary traffic. Our team will present how we used Bro and other tools to discover indications of compromise (IOCs) from past datasets, and then used this insight to develop Bro scripts that detected those IOCs on a live network. Our techniques were evaluated during the 2017 Cyber Defense Exercise, where undergraduates compete against the Nation Security Agency (NSA) Red Team. Additionally, we will provide observations how Bro performed as part of a greater security architecture, which included the Snort Intrusion Detection System and an implementation of an Elasticsearch, Logstash, Kibana monitoring suite.

When you are performing debugs you have at least two concerns: 1) making sure the that debug does not clobber the CPU of your device, and 2) filtering the debug output to get to the information that you need for troubleshooting your issue. The debug interface command can help you with the second issue. In many cases (especially on production equipment) you may have a lot of interfaces running the protocol that you are troubleshooting. When you enable a debugging command (like debug ip ospf hello), the output that will be returned is for all interfaces running that protocol. This can quickly overwhelm you with information and make troubleshooting more difficult/time consuming. The debug interface command allows you to limit the debug output to a specific interface.

+++See my latest video: Internet Security or Die+++ https://youtu.be/CzB5n6_pBfk TRANSCRIPT Address Resolution Protocol - ARP Tutorial. TCP/IP Explained TRANSCRIPT: Today I teach you ARP, which I've had several requests from my viewers to do. That's Address Resolution Protocol. The first thing you want to know about any protocol when you're learning it, is where do you find the protocol on the TCP/IP Stack? We see here that ARP is located on the network layer. Not on the data link layer as some folks mistakenly believe Here we see a LAN w 3 computers on it. Notice that each computer has 2 addresses, and IP address and a Mac address. The IP address is a logical address that the admin assigns to each host either manually or more likely with DHCP. The IP address is 32 bits long and is on the network layer of the TCP/IP Stack. The Mac address Is a physical address, that is actually burned into the network interface card or NIC. The Mac address is 48 bits long and is on the data link layer of the TCP/IP Stack. Suppose we want to send a message from host A to host B. We start at the point where the Network layer of the OSI has recd a message to send from the layers above. This is encapsulated into a packet by appending a header to it, that has the dest IP address in it. At this point it is passed down to the data link layer where a new header needs to be appended with the dest MAC address. The question is: How does Host A know the MAC address of host B? The Answer is: Host A broadcasts an ARP Request To help us understand the ARP request, lets look at a ARP Header Click on the following fields & ad lib each: Operation, Sender HW Address, Sender Protocol Address, Target HW Address, Target Protocol Address Back to where Host A broadcasts an ARP Request. The reason it broadcasts is that it doesn't yet know the MAC address to send it to. Essentially the request is saying: If your IP address is 10.1.1.2, then tell me your MAC address. Let's see the parameters in the the ARP Request [show parameters on Hard Copy] as they magically Appear. Now Host A recvs the unicast ARP reply & it becomes aware of the Host B's MAC address & it caches it. Also when Host B recd the ARP request, it became aware of the Host A's MAC address, and it cached that. Note therefore that Host B does NOT need to send an ARP request to find Host A's MAC. So now both Computer A & B are each aware of the others MAC address, they can communicate back an forth over TCP/IP. Now let's look a a different case. Suppose that Host A wants to go to the website Packethacks.com. How does ARP work then? Host A should already have the default gw of 10.1.1.4, which is the router that leads out to the internet. So it does an ARP request to find the MAC address of the rtr. When it recvs an ARP Reply back from the rtr, it caches the MAC address. And the Rtr caches the MAC address of Host A. Now when Computer A wants to talk to website Packethacks.com it simply sends all packets to the router, and the router is responsible for sending the packets to the next hop on the way to Packethacks.com Just to drive home the point, what are we likely to see in the rtr's ARP cache? Host A's IP & Corresponding MAC Address, Host B's IP & Corresponding MAC Address, Host C's IP & Corresponding MAC Address - because if Host B or C had recently accessed any website on the internet, then these wouls be caches. And also another entry with the IP & MAC of the next hop rtr to get to the Packethacks.com.

Objectives Part 1: Build the Network and Configure Basic Device Settings Part 2: Determine the Root Bridge Part 3: Observe STP Port Selection Based on Port Cost Part 4: Observe STP Port Selection Based on Port Priority Background / Scenario Redundancy increases the availability of devices in the network topology by protecting the network from a single point of failure. Redundancy in a switched network is accomplished through the use of multiple switches or multiple links between switches. When physical redundancy is introduced into a network design, loops and duplicate frames can occur. The Spanning Tree Protocol (STP) was developed as a Layer 2 loop-avoidance mechanism for redundant links in a switched network. STP ensures that there is only one logical path between all destinations on the network by intentionally blocking redundant paths that could cause a loop. In this lab, you will use the show spanning-tree command to observe the STP election process of the root bridge. You will also observe the port selection process based on cost and priority. Note: The switches used are Cisco Catalyst 2960s with Cisco IOS Release 15.0(2) (lanbasek9 image). Other switches and Cisco IOS versions can be used. Depending on the model and Cisco IOS version, the commands available and output produced might vary from what is shown in the labs.
