I am able to view the frames as they come through but I have yet to find a way to see how much data is actually being sent.
Here is the trick. You can use "tshark" to capture the data in/out from web-socket. Or you can use the graphical version of tshark called Wireshark. If you are wanting to print the capture via your progarm (java file) then you can do Runtime.execute("tshark command here"). This must be the one way. Web-socket is a TCP socket between server and client. Wireshark can easily to this.

I have written a few dissectors in Lua for Wireshark, for example. I would like to know if Devtools can be extended to achieve similar effects. There are a few reasons this is desirable:
Installing and using Wireshark often mandates privileged access.
Capturing traffic from the loopback NIC on Windows remains problematic.
websocket traffic is included in saved HAR files, suitable for later dissection.
Devtools can inspect SSL secured websocket frames with zero user effort.
It's possible with Firefox.
There is an addon already that hooks into the WebSocket data. It can do some additional parsing of protocols on top of WebSockets like MQTT.
https://addons.mozilla.org/en-GB/firefox/addon/websocket-monitor/
It appears to hook into nsIWebSocketEventService to get the data. I haven't found any documentation for it.
https://github.com/firebug/websocket-monitor/blob/master/lib/wsm-actor.js#L80
Chrome does not appear to allow access to WebSocket frame data through an API.
You may be able to modify the WebSocket constructor to allow you to intercept the events from your plugin.

I am learning Wireshark as part of a course. I would like to know how to use the wireshark display filters for filtering traffic of a particular application. I tried using the display filter reference for Skype present on the link below:
https://www.wireshark.org/docs/dfref/s/skype.html
However, I am not able to filter the Skype traffic from the capture I have. Can anybody please suggest an approach to filter Skype traffic?
I know how to filter traffic based on the source/destination IP address, protocols but I would like to know how to capture an application specific traffic eg for Skype.
Are there any other tools which would be better in filtering a particular application traffic from a complete packet capture?
I guess in your case there coud be helpfull rawcap.I used it to eavesdrop on my applications.Data captured by rawcap can be opened with wireshark.I was using it on loopback.You shoud be able to listen to skype as well.After you captured enought data close it with ctrl+c if i remember correctly and then open the file you saved all the informations in with wireshark
Skype uses a different protocol nowadays (if you're using a new Skype version). It looks like normal SSL (HTTPS) now. The old Skype dissector in Wireshark is therefore quite useless now.
Try loading the PCAP file into CapLoader and look at the long duration flows (probably to TCP port 443). Select those and export them to a new PCAP file.
I have a program that I'm trying to reverse engineer.
It gets a specific key by using HTTP GET on some URLs.
I need to figure out the details on how this works.
The good news is that there's the option to preform these requests over an HTTP proxy.
Would anybody know of a program to monitor a specific application's network traffic?
I've tried Wireshark, but its no giving me enough information (Headers, URL path).
After Wireshark, I tried FreeProxy. The problem with FreeProxy is that it only gives headers for around 1/3 of the requests and it doesn't give the full path either.
Could anyone suggest a better alternative for monitoring the internet activity of my application?
I thought Wireshark was able to capture the full packet with all its content? If so, how can it not give you enough information? Maybe you need to revise your traffic capture config?
It's been a while since I used Wireshark, but if you have trouble capturing full packets, what you can do is use tcpdump to capture and write to file, then view the capture file using Wireshark. tcpdump's -s option will allow you to set the packet size so as to capture full packets.
I use Fiddler for all my HTTP traffic monitoring. It is very powerful and displays data in the HTTP layer only. Wireshark will get all of your data, but it displays the details at a much lower layer. It even has capability to decrypt SSL traffic.
Fiddler installs itself as a proxy, and configures IE and FF automatically to use it when it is on. If you are having too much traffic mix in, then you can install Fiddler on a remote box, and point your proxy to that IP address.
I was recommemded another program called "mitmproxy" which worked perfectly for what I needed. Fiddler also worked, but SSL was giving me problems.
Is there a program available that will allow me to interactively write HTTP stream data and send it to a server? Ideally I'm looking for a console app that will allow me to type or paste HTTP headers and body, send it to my server, and get the response headers and body back.
Does such a program already exist?
I'm running W7 64-bit with .NET 4.0.
if you change your mind and want a GUI app
http://code.google.com/p/rest-client/
or you can also use fiddler
Edit:
http://code.google.com/p/rest-client/ also supports commandline
Maybe telnet is an option for you? If it's not already installed on your machine, take a look at this guide from MS.
To connect to your server use it like this:
telnet www.myserver.de 80
After the connection is established, you can paste your HTTP GET reqests or what ever you like.
tinyget is a useful MSFT tool that will make simple get requests. You can store these requests in text files and stream them in.

Is there a way to monitor the FTP port so that I can know what commands my FTP application is sending to a FTP server?
I am using a closed-source FTP client application, which is not working with a closed-source FTP application server. The client and the server are not communicating well with each other, and I would like to find out why. I wish to reverse-engineer the client to see what commends the client are sending to the sever. I used a web test tool before that allowed me to monitor the content transferring through HTTP, but I can't seem to find such tool for FTP. I appreciate it if you can help me out, thanks.
Sounds like you need a packet sniffer - assuming your network admins/company policy allows it...I have used wireshark fairly successfully before.
The core FTP commands should be visible in the packets.
You can use the Wireshark application: http://www.wireshark.org/
It should have decent parsing capabilities for FTP as well as other protocols.
Can you configure a proxy with the client? Then you could install an ftp proxy server using the logging on that to see what's going on?
There's a proxy server for Linux here: http://frox.sourceforge.net/doc/FAQ.html
Paul.
Do you have access to ftp-server logs? Its likely those commands would be logged there.
If they aren't, your next option would be to configure the server to log them, if you have access.
If thats not an option or server does not log such things, then you have to go to either packet sniffer or a proxy, as suggested by previous posters.
On Unix, tcpdump might be your friend. Maybe you should first state which OS you're targeting, though.
If you have the ability (often requiring root access) to use a packet sniffer, tcpflow sniffing the TCP control channel will show you the commands and responses going back and forth in an easy-to-read format.
If you don't have such access, tools such as ktrace and strace will allow you to see all data read and written on the socket for this connection, though it will be a little work to extract it.
If you could tell us just what tool you were using for HTTP traffic, that would allow us to look for something similar for FTP traffic.
