Generate dump file

Generate dump file for tn3270 protocol

Pre-requisites

• Must have x3270 installed. (if running a macOS use brew)

How to generate the dump file using x3270

1. Open x3270, configure your mainframe specifications such as screen size, extended field option, and all configurations required to emulate a connection against your mainframe.

2. Once you have everything configured, you have to select the option on the File window Trace data and Events

3. Immediately after enabling that feature, x3270 will ask us to configure the destination path folder as well as the file output name. It could be something like this:

   

4. Then just press TRACE, connect to your mainframe, and interact with the emulator as normal. Make sure you run the same flow that is causing problems on the RTE-Plugin!

5. Send us the output.txt file.

Generate a dump file for Vt420, Tn3270, and Tn5250 using Wireshark.

Pre-requisites

• Must have installed Wireshark

How to generate the dump file using Wireshark

1. Open Wireshark and select the interface you are currently using to connect to the mainframe. (Ej: Wifi, LAN)
2. Then go to the emulator of your choice and run the flow that you are getting errors on the RTEPlugin.
3. Once you finish the flow, go to Wireshark and stop the recording.
4. In order to generate the JSON file that we need to reproduce your issue, go through File -> Export Packet Dissections -> as JSON
5. In order to reproduce the flow, we need to know the protocol that you are using, terminal type, as well as the IP for a mock creation. But you have to change the real IP address to a fake one. In order to do that just open the generated JSON file and search for the original IP, replace it for 0.0.0.0.
6. Send us the JSON file.

Here there is a video example to generate TCP dump with Wireshark.
