Wireshark

Another option which has not been suggested here is to run the app you want to monitor in the Android emulator from the Android SDK. You can then easily capture the traffic with wireshark on the same machine.
This app was a lifesaver I was debugging a problem with failure of SSL/TLS handshake on my Android app. Tried to setup ad hoc networking so I could use wireshark on my laptop. It did not work for me. This app quickly allowed me to capture network traffic, share it on my Google Drive so I could download on my laptop where I could examine it with Wireshark! Awesome and no root required!
I had a similar problem that inspired me to develop an app that could help to capture traffic from an Android device. The app features SSH server that allows you to have traffic in Wireshark on the fly (sshdump wireshark component). As the app uses an OS feature called VPNService to capture traffic, it does not require the root access.
I wanted to share a wireshark of my file, because it may help with some problems i'm having but i need to know if it is safe, or if could reveal sensitive data about me, the only IP's i see are my internal ones not external
I think it largely depends on what else you were doing at the time you created the capture. For example, if you were browsing the web, then obviously people would be able to see what websites you were visiting and the content of any unencrypted pages. If you were logging in to something that does not use encryption (for example, telnet, FTP, or a non HTTPS website) then your login information could be in the wireshark capture. Granted, this is fairly unlikely as encryption is used for nearly all logins these days.
Other than that, the wireshark capture will contain broadcast packets from other devices on the network, in addition to MAC addresses. These are fairly unlikely to contain any sensitive information; some people may consider MAC addresses to be sensitive, since they are unique to each device, but unlike public IP addresses they cannot be easily linked to a location or specific person. All it really reveals is the manufacturer of the computer/network card.
It depends on what information you captured with Wireshark, and who you are sharing it with. If this is at work, and someone from your technical department is asking for it, and you are sure it is a person from your tech department (and not an imposter), you are probably safe to share it with this person, and only this person. I definitely would not post the wireshark file into a forum such as this one, or put it anywhere where other "random" people can access it.
I am trying to monitor the OPC UA connection between Ignition and client with wireshark, i set wireshark to check ports 4096 and 8088 but i am only seeing TCP/UDP communications , i am trying to achieve something like the snapshot in the attached file. Pleaseeee!!! could anyone help? I have been on this for days
Thanks
Ok let me explain the configuration:
Ignition server is installed on a system with a PLC connected to it, i connected to the PLC from a client PC through the server, the connection was established and we can see that it is connected. I tried to monitor the communication using wireshark on the server and on the client system, but i have not been successful so far.
I need to present this product to my superiors but i want to show them the OPC UA communication with wireshark.
Thanks
Hi,
Thanks, i think i figured it out, when i followed a TCP packet i saw the encrypted information shown in the snapshot, i guess this is the connection.
Thanks

The trick is to launch an ssh session without a login shell and run tcpdump through it on the remote system making tcpdump write raw packets to STDOUT while piping it to our local wireshark reading from STDIN.
Tcpdump does buffer the output when writing to a file (our STDOUT in our case), which unfortunately means it might take some time until we can see the traffic in wireshark. Tcpdump offers options to influence the buffering however this is not implemented in our version of Libpcap (tested on 11.4HF1).
This is especially annoying if we want to capture low volume traffic. What we could do is capturing icmp echo requests+replies additionally to the traffic we are interested in, and remove them again with the wireshark display filter. Then start a ping to push the interesting packets to wireshark faster.
copy the plugin files manually from SmartRF Packet Sniffer 2 install location (\wireshark\plugins\3.0.x) to Wireshark plugins folder (\plugins\3.0\epan). Use the x86 version of plugins if you have a 32 bits installation of Wireshark or the x64 if you have a 64 bits version of Wireshark installed.
The data in wireshark and the data from MRTG are different types of data. I have never heard of using wireshark to create graphs for management. What information are you trying to show them? Bandwidth usage? Wireshark is the wrong tool for that. Wireshark is a deep network analysis tool, capturing everything.
First, you can use the filters in wireshark to filter the dataset both during capture and while displaying it. That does not get you a nice graphic report, but it may help to identify what you do need to capture.
The docs at wireshark.org give an excellent idea of what you are looking at. You can follow particular streams that give you the data you are looking for. To be honest, bringing together multiple tools when one can provide you the data you need can only introduce further complication.
Because you cant be a good network engineer if you do not know how to drive wireshark, i decided to put a post up on how to capture and analyse TLS negotiation. For this purposes, I used www.cnn.com. Before you do the capture, its good to do an nslookup for the domain so you can filter out relevant traffic (yes wireshark calls it 'ssl'). But really you can just use the public IP address on your loadbalancer (or F5) if that is what you want to analyse. So hit your website, using https. Once pulled up, stop the capture.
I am using Ubuntu 18, and wireshark-gtk. I followed this and this tutorials to create a column named/showing frequency/channel.But all the packets I captured have no frequency/channel showing.I tried sample packets submitted by others from wireshark.org and the frequency/chennel shows up. What might be the problem. I am trying to find the channel a packet is captured.
I found out that RadioTab headers are not part of any Dot11 protocol but are merely added by the network interface. And the reason I got the RadioTab headers on sample packets from Wireshark.org and not from my wireshark live capture is because some network adapters do not add RadioTap header while others do and the network adapter of my laptop does not add RadioTab headers. I checked this with a new external wifi adapter and it did add the RadioTap headers.
