![]() If the clients (SAPGUI, Wireshark) are all on the M1 MacBook, the SAP VM and the clients operate as nodes on a UTM NAT network (usually 192.168.65.0/24 but some screenshots were taken before doing a Hypervisor upgrade, when the NAT network was 192.168.64.0/24) if any client is on the Intel-based MacBook, the SAP VM and all the clients operate as nodes on the Wi-Fi network. The two physical machines are on the same (home Wi-Fi) network 192.168.68.0/24. – An Intel-based MacBook, on which there is a Hypervisor called VMware Fusion, on which we run one or more Ubuntu VMs (amd64). – An M1 MacBook, on which there is a Hypervisor-Emulator called UTM: the SAP system VM is an (emulated amd64) SAP NetWeaver 7.52 SP04 Developer Edition, installed using the advice in a blog I wrote in 2022 then there are one or more Ubuntu VMs (arm64). The system landscape for the various demos consists of… And we look briefly into how to retrieve SAP data using the SAPDIAG protocol Dissector of the Wireshark plugin. We also show how to make sure that remote capture (via the sshdump tool) is available in all the Wireshark instances you install, and how you can remotely capture SAPGUI traffic. We show some effective ways to get a Wireshark+SAP-Dissectors instance up and running on Ubuntu Desktop 22.04 LTS for amd64 (x86_64) and arm64 (aarch64) architectures, as well as on an Intel-based (amd64) MacBook and on an M1 (arm64) MacBook. Wireshark can also be used to analyse SAP-specific network traffic – such as for example SAPGUI traffic and RFC traffic – using a most excellent Wireshark plugin for SAP Dissectors, the code for which is maintained by SecureAuth on GitHub: In closing, Packet Sender is a useful and practical application that you can resort to, should you need to send or receive data packets in your network, its usage translating into minimal strain on your system’s resources.Wireshark is a popular and free open-source toolset for analysing network traffic: A lightweight network packet transfer utility In the ‘Traffic Log’ you will be able to view all sent and received data, while from the ‘Settings’ section, the tool’s ‘Display’ and ‘Network’ options can be configured according to your specific needs. You can then click the ‘Send’ button to dispatch your packet, or you can ‘Save’ it for later. The program allows you to choose the protocol you prefer, between UDP and TCP, from a dedicated menu. You also have to enter a port number between 5, as it cannot be left blank, nor can you enter 0. Next up, you will need to input the IP address Packet Sender supports IPv4, IPv6 and DNS Lookup. Entering either one of the two will automatically generate its equivalent in the other code type, so you do not need to calculate the HEX correspondent of a written message, for instance. Swiftly send and receive network packetsįor starters, when sending a new packet, you need to specify its name, then input its ASCII or HEX representation. The main window allows you to specify the details of the piece of data that you wish to dispatch, the panels on the second half allowing you to further benefit from the utility's features. Neatly-organized and compact GUIĪppearance-wise, the program is fairly easy to understand and work with, its straightforward looks making it accessible even to the less knowledgeable individuals. Packet Sender is an intuitive and very simple to handle piece of software created to assist you in sending as well as receiving TCP and UDP packets to a preferred address in your network.
