A reader recently asked for my opinion on building a server to be dedicated to network traffic capturing with Wireshark. Site-KB/VoIP-devices-configuration/rpcapd/rpcapd-1.png' alt='Capture Serial Port Data Wireshark' title='Capture Serial Port Data Wireshark' />While Wireshark is an excellent packet analysis application, its graphical interface is quite demanding on system resources memory in particular and is intended for use only in low throughput environments or offline packet analysis where packets are read from a file on disk. For persistent traffic collection, such as that performed by an IDSIPS, many people opt to use the popular packet capture utility tcpdump. Alternatively, the Wireshark package includes a very small command line utility less than one tenth the size of tcpdump called dumpcap. I explained in the article Sniffing with Wireshark as a Non Root User that Wireshark relies on the dumpcap executable for its core packet capturing functionality, with more complex features offloaded to the Wireshark GUI and tshark. In fact, the Wireshark capture options dialog pictured below is primarily a wrapper for arguments passed to dumpcap. Igi Project Unlimited Edition'>Igi Project Unlimited Edition. Wireshark to capture packets to a file or series of files on disk, and makes for an efficient long term capture solution. Further, like tcpdump, it is built on the libpcap library and uses the same capture filter syntax. We can start a very basic packet capture by invoking dumpcap with the command below. Ctrl C terminates the capture cleanly. File packets. cap. Packets 6. 25 Packets dropped 0. K 2. 01. 1 0. 3 0. Now we have a 9. 42 KB capture file that we can open in Wireshark for analysis at our leisure. Of course, if we intend to capture gigabytes of data, a single file becomes too unwieldy to manage. We can tell dumpcap to begin writing a new file every time the current file reaches a given size in kilobytes. The filename given will be appended with a serial number and timestamp to ensure uniqueness. File packets0. 00. Packets 7. 78. 8 File packets0. Packets 1. 78. 87 File packets0.

We can also use the duration keyword in place of filesize to specify a length of time in seconds to spend filling each file for example, one hour, or 3. And to avoid eventually filling the entire hard disk with capture files, we can include the files parameter to set up a ring buffer Once the maximum number of files have been saved, the oldest file is deleted and a new empty file is created in its place. The example below shows how we can instruct dumpcap to maintain a rotating record of the last 2. As I mentioned earlier, we can also specify a libpcap filter to restrict the types of traffic captured by dumpcap. For example, the following command captures only DNS traffic destined to or coming from 2. A full description of libpcap filter syntax is available in the libpcap filter manpage.
