Icmp: to restrict recording of the packets only to the ICMP packets. On the first sub-net, I need to specify 2 IPs directly, on the remaining sub-nets I could grab all the traffic from. I am using WS1.8 and running on Windows 2003. It shows how to match against subnets using CIDR notation. Hello, I need to capture all the traffic from 12 IP addresses. The following is a list of some commonly used tcpdump options supported with the nstcpdump.sh script: Refer to this part of the Wireshark user guide, especially the bit that talks about IPv4 addresses. Note: Unless you have specified a packet count, discussed later in this article, you must stop the nstcpdump.sh script either by running the kill command or by pressing the Ctrl+ C keys simultaneously. The following is the syntax to run the nstcpdump.sh script: To run the script, you must switch to the shell prompt of the ADC appliance by running the shell command from the command line interface of the appliance. Most of the entries in the output of the script have the data in the form of an IP address, TCP or UDP port number, or physical interface. NOTE: Before you run the nstcpdump.sh script you must decide the data you want in the output of the script, else a large amount of unnecessary data might be available in the output. ![]() Wireshark displays the packets that are captured, only you can determine if those packets belong to your mysterious device as there is nothing in Wireshark to 'find' an IP, it only displays them. NOTE: nstcpdump is NOT RECOMMENDED for use on modern ADC versions, due to it's ability to interfere with Netscaler operations (especially on single-packet-engine VPX's) which can lead to traffic interruptions and even crashes in severe cases. Wireshark can only capture packets that 'pass through' the interface you are capturing on. This article contains information about the commonly used options and filters with the nstcpdump.sh ADC script.
