Data written to the pipe is neither in a supported pcap format nor in pcapng format

edit

What were you doing when that happened?

i'm having the exact same problem for a Hands On Project for a Networking Concepts course. I'm also a total newb to this and am utterly lost.

You're asked in step 2. "Start Wireshark and click Capture Options. In the Capture Filter text box, type icmp, and then click start."

It is then when I receive an error message stating the above:"Data written to the pipe is neither in a supported pcap format nor in pcapng format. Please report this to the developers of the program writing to the pipe."

Please help.

I got same prlblem after I run plink.exe -ssh -pw xxxxx [email protected] "tcpdump tcp -U -s 0 -i eth0 port 80 -w -" | "C:\Program Files\Wireshark\Wireshark.exe" -k -S -i - got the message "Data written to the pipe is neither in a supported pcap format nor in pcapng format. Please report this to the developers of the program writing to the pipe." Waitting for the solution!

I met similar problem, when I using plink -ssh remote to a server running dumpcap for remote trace and the wireshark popup this error message, I'm running the wireshark v3.2.4 and putty v7.3. Finally, the problem solved with reinstalling a older version putty v7.0. Or you would just download a plink.exe v7.0 and replacing the v7.3, it is also working properly afterward.
