Hi Krishnamurthy, Wireshark uses an executable called dumpcap to perform the actual capture. You can use dumpcap directly from the command line, and as dumpcap doesn’t build the structures that Wireshark builds you won’t have a memory problem. You can then view the resulting pcapng file with Wireshark in the normal way.
You can find more information here - https://community.tribelab.com/course/view.php?id=10 – including a video explaining the use of dumpcap.

So, If I am sending continuos stream of data at the line rate(1gb/s) and if I am using wireshark to capture the content, it will crash after sometime due to memory exhaustion. Is there any way to bypass this ? (Any free function/some other work around) Any suggestion from your side would be extremely helpful.

Are you assuming that epan_get_frame_ts() returns a pointer to a freshly-allocated structure that must be freed when the caller no longer needs it? If so, no, it doesn't. You do not need to free the structure. ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <[email protected]<mailto:[email protected]>> Archives: https://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-dev mailto:[email protected]<mailto:[email protected]>?subject=unsubscribe ______________________________________________________________________ This message contains confidential information and is intended only for the individual named.
