For Windows Operating Systems (OS), you can also use the Microsoft packet sniffer, Microsoft Network Monitor (article ID: KB933741) which is free for download and commercial use. While Pulse Secure does not advocate or condemn the use of any such packet sniffer in particular, we commonly suggest the use of Wireshark as the full version is freely available for commercial use and it is supported on a wide range of platforms (Windows, Mac OS, Linux, and so forth). See Wireshark’s FAQ for additional details. Such a packet sniffer will be required by Pulse Secure Support in order to validate the traffic pattern(s) and behavior on the client machine’s local network. Please ensure that the packet sniffer which you chose will allow you to save the TCP capture in either pcap or tcpdump(.dmp) format.

Pulse Secure does not assume any responsibility for the selection of or use of these third party sites and products, so we do ask that you take the time to evaluate and gain the necessary approval needed to install such a program on the designated client machine and Application Server (if possible) prior to starting the log gathering process. There are several packet sniffers available today for a price and others available for free for download and use. Packet Sniffers are programs for capturing live traffic on a client network.
