TCP Tips and Tricks - What Makes Applications Slow? - Sharkfest 2016 (by Chris Greer)
This session was presented at Sharkfest 2016, held at the Computer History Museum in Mountain View, California - June 13-16th 2016. www.packetpioneer.com In this video, we will look at several example trace files that demonstrate how TCP behavior can impact application performance. Rather than starting at the cable and working up to the application in the OSI model, we will learn how to start at the transport layer, reducing the amount of time it takes to solve the problem. We will also look at issues with TCP windows, TCP MSS, and how to interpret retransmissions and out-of-orders. Instructor: Chris Greer, Network Analyst, Packet Pioneer, LLC Chris is a Network Analyst for Packet Pioneer, a professional services and training company. He regularly assists companies in tracking down the source of pesky network and application performance problems using a variety of protocol analysis and monitoring tools including Wireshark. Chris also delivers training and develops technical content for several analysis vendors. In addition to digging through trace files, Chris enjoys helping others to learn the art of analysis via onsite courses, blogging, and his YouTube channel.

Wireshark 101: Fixing Network Problems with Wireshark, HakTip 134
Today on HakTip, Shannon explains how to fix a network or connection problem based on the information you receive from Wireshark. How to tell if a website is down via Wireshark: This is a pretty common problem, and sometimes the issue can be within your network, sometimes outside it. If several people are having the same issue, it's either because the website is down, or your network is messed up. In my case, I want to visit threatwire.com (which I know is currently down). Each time I try, I'm sent back an error saying the site isn't available. If I try to find it in Wireshark, it's tough to tell. Do a cmd ping of threatwire.com and you should see a bunch of requests timed out, but you'll also see the IP address of the site. So let's search for that IP address in Wireshark, we see that I have 4 ping requests for the IP address. If I searched for it in the browser, I'd get a bunch of synchronize packets, but no answer, so it keeps trying to retransmit up to three times. If we take a closer look at the info dialogue, the ping requests all say "no response found" while the TCP packets just say 'retransmission'. If we look at other packets in this capture for other sites and within my network, we can prove that the problem only occurs when trying to visit this one site, not the entire network. What else can we figure out? I've run into a problem where I couldn't access the internet but all my coworkers could. We used a single router and IP addresses came from DHCP. By using Wireshark I was able to determine that the problem was with DNS. I was able to reach my router and my computer had no problem connecting to it, but couldn't figure out the DNS request. Everyone else could log onto the net, so it must've been my computer. We were able to find the problem was because I had to manually set my default gateway address instead of letting it be DHCP-assigned. Switched it back, and it worked! What if you can access the net but keep getting a 'can't display webpage' error in your browser? If you're on a small network, and pull up Wireshark, this would show you sending the site a TCP packet, but getting an RST error back (reset packet). That packet terminates the communication, and after a few seconds the browser gives you an error. If you're able to send a TCP packet through your router to the net but have trouble sending a DNS query, it could be because the host file for your device already has the DNS mapped to that IP or because it's mapped in the DNS cache. Check your computers host file for the easiest solution, and remove the DNS mapping if it's in there. By checking Wireshark and understanding the packets, you can fix problems faster for your network. There are a ton of other problems that can occur when trying to establish a connection to the outside would, so read up on some of them with all the resources available on the internets!

Multitrace NAT analysis Using Wireshark
NAT Packet Analysis Using Wireshark One of the most popular questions I get when people get the hang of protocol analysis is the daunting exercise of multitrace analysis. As with anything else the best advice is to start with the basics before tackling anything complicated. Multitrace analysis is only effective if you truly understand your vendors products, networking and how it relates to the OSI model or packet analysis. I always suggest that you start at layer 1 and work yourself up. The key is to know what fields in the frame or packet changes, or remains the same. Ideally when you figure this out you can use a better capture or display filter A multitrace capture of a hub, switched, or bridged network is most straight forward since a hub or switch is transparent at layer 1 or 2 and doesn't change anything in the packet. When you move up to layer 3 or routing, several things change in the packet such as MAC address, IP TTL and TOS. Of course your mileage will vary, and any device could be configured to muck with more bits in the packet, but I figure I would give you a point of reference. At layer 4 we get into application gateways, proxy, firewalls and NAT type devices where the following packet fields gets modified; MAC address, IP address, IP TOS, TCP/UDP port numbers, TCP ACK/SEQ values, etc. Lastly at layer 7, we are dealing with multi-tiered applications and basically everything changes in the packet. In this video example I do a multitrace analysis of a simple netgear router/NAT/firewall device where I take a trace from the WAN and LAN side to compare. Not to sound like a broken record, but please remember that your devices might behave totally differently and these notes and techniques should only be used as a reference in your environment.

Documenting Why “Its Slow” With Wireshark
I can’t tell you how many times I have heard that dreaded phrase, “Its Slow”. I’ve heard this so many times I typically casually respond with, “Great, what is it and how slow is slow?” The biggest issue I have with this statement is that this is the typical network complaint that sucks you into the troubleshooting vortex since nothing is clearly defined. For example, if I said, “email is slow or it takes 2 hours to download my files” you have a chance to address this since I can measure the problem and the end result. The 2 hour comment actually gives you a measureable value to compare against. One of the toughest things about troubleshooting is when an assumption is made like drive x on the server is fine, therefore the server is fine. In this example I wanted to demonstrate to a client that one disk or file system on a server can be slower than the other. I also taught him some Wireshark tips and tricks along the way to help him in the future. Enjoy

Wireshark and Recognizing Exploits, HakTip 138
This week on HakTip, Shannon pinpoints an exploitation using Wireshark. Working on the shoulders of last week's episode, this week we'll discuss what exploits look like in Wireshark. The example I'm sharing is from Practical Packet Analysis, a book by Chris Sanders about Wireshark. Our example packet shows what happens when a user visits a malicious site using a bad version of IE. This is called spear phishing. First, we have HTTP traffic on port 80. We notice there is a 302 moved response from the malicious site and the location is all sorts of weird. Then a bunch of data gets transferred from the new site to the user. Click Follow TCP Stream. If you scroll down, you see some weird gibberish that doesn't make sense and an iframe script. In this case, it's the exploit being sent to the user. Scroll down to packet 21 and take a look at the .gif GET request. Lastly, Follow packet 25's TCP Stream. This shows us a windows command shell, and the attacker gaining admin priveledges to view our user's files. FREAKY. But now a network admin could use their intrusion detection system to set up a new alarm whenever an attack of this nature is seen. If someone is trying to do a MITM attack on a user, it might look like our next example packet. 54 and 55 are just ARP packets being sent back and forth, but in packet 56 the attacker sends another ARP packet with a different MAC address for the router, thereby sending the user's data to the attacker then to the router. Compare 57 to 40, and you see the same IP address, but different macs for the destination. This is ARP cache Poisoning. Let me know what you think.

Packet Loss vs Latency
https://www.thetechfirm.com I get involved with a lot of performance related troubleshooting and the majority of the time the root cause is related to packet loss or excessive latency. Let me start with explaining the difference between the two terms. Packet Loss is literally when you do not receive a packet. This can be caused by a variety of reasons such as corrupted frames, RF interference, half full duplex mismatches, dirty fibre connectors, oversubscribed links and routing issues. Packet loss is an issue since TCP based protocols will have to wait and retransmit lost frames. The key word here is ‘wait’ since waiting implies you are no longer transmitting. For example, if you had a 500ms delay on 10 Mb link, you lost the opportunity to transmit 5 Mb within that 500 ms time frame. If your application is UDP based, all bets are off and it is up the application to decide what to do. I’ve seen UDP based applications react to packet loss by terminating the connection, resend data or corrupt data. With VOIP you hear echo and distorted audio. read the rest at https://www.networkcomputing.com/networking/packet-loss-vs-latency-analyzing-impact/523143466

Wireshark 101: Understanding High Latency, HakTip 136
Today on HakTip, Shannon explains high and low latency, and how to determine which machine is causing the latency via Wireshark. We have discussed high latency a bit in my previous HakTip, but I wanted to go into it with some more detail. As you look at packets in a Wireshark capture, you'll notice that with a normal connection, your transmission happens in under a second. Now if you look at a few packets with slow communication, they show up to be almost a second each. This would be called wire latency because of the slowness happening on the wire, not the source or destination. Now what if the slow one happens to be the HTTP get request? In this case the only latency is happening from the client, so there must be an issue on the clients machine. Lastly, if the slow packet happens to be from the server as an HTTP packet, we know HTTP has to go through the application layer and it takes some processing... the server must be having an issue with processing that packet. Next up is a network baseline. Knowing what your network baseline is is important in figuring out network issues. A baseline is an understanding of what kind of latency your network usually runs at, and what you should normally expect. If you need a site baseline, you'd probably want to record normal protocols in use, broadcast traffic, authentication sequences, and data-transfer rates. For a host baseline, record the protocols, idle and busy traffic and times, startups and shutdowns, authentication sequences, and associations and dependencies. For an application baseline, you'd want to pay attention to protocols, startup and shutdown procedures, associations and dependencies, and data-transfer rates. Depending on how busy your network might become (i.e. a bank has busiest hours during lunch time, and it dies off in late morning or when they are closed) you might want to make several baselines for different times of day. Keep your baseline secure, and make your own .pcap files of each. Let me know what you think.

I'll be there, reminding you to trust your technolust. -~-~~-~~~-~~-~- Please watch: "Bash Bunny Primer - Hak5 2225" https://www.youtube.com/watch?v=8j6hrjSrJaM -~-~~-~~~-~~-~-

Capturing network Traffic Using Windump with Wireshark
Wireshark, a network analysis tool formerly known as Ethereal, captures packets in real time and display them in human-readable format. Wireshark includes filters, color-coding and other features that let you dig deep into network traffic and inspect individual packets. This tutorial will get you up to speed with the basics of capturing packets, filtering them, and inspecting them. You can use Wireshark to inspect a suspicious program’s network traffic, analyze the traffic flow on your network, or troubleshoot network problems.
