That means that all of the packets involved with your browser access will also be captured. It is important also to note that when you access the DCP you are also using the network. So if your JNIOR has only been up for 16 minutes that is all that you will get. Notice that in my example only the past 16 minutes were captured. If you have Wireshark installed you will likely be able to double-click this PCAPNG file and it will open right up for viewing and analysis.īy the way you can download Wireshark for free from. You can download this file to your personal computer. For example: HoneyPot /> netstat -cĬollected 4791 packets from the previous 16 minutes

The NETSTAT -C command generates a network capture file /temp/network.pcapng on demand containing the content of the capture queue. Depending on your network usage that queue might contain the past hour of traffic or much more. Once the queue fills the oldest packets are dropped. A large queue is established at boot and a record of network packets is kept. The JNIOR captures network traffic continuously.

(ether=0x0 and ether=0x0f and ether=0xcc) or (ether=0x0 and ether=0x0f and ether=0xcc) You could also just examine each byte individually: This filter uses "ether" and "ether" to examine the first four bytes of the destination MAC address and source MAC address, but then uses "& 0xffffff00" to mask the fourth byte before making the comparison. So "ether" is valid, as is "ether" or "ether" but not "ether". The problem I ran into was that we're trying to examine three bytes, but the length value in a capture filter byte offset expression can only be 1, 2, or 4 bytes. This was only a first attempt for me at using byte offset notation in a capture filter, so maybe someone can shorten the syntax. I was able to limit my capture to traffic to and from Netopia devices (OUI 00:0f:cc) with: There are no keywords that let you do that, but you can accomplish what you want with a byte offset filter.
