I use wireshark windows Version 3.4.0 with sshdump. But when I try to capture my remote Linux server, sshdump have below error, seems sshdump is too old are not support some DH key exchange algos?

Error by extcap pipe: * (sshdump.exe:4708): WARNING *: Error creating connection.

* (sshdump.exe:4708): WARNING : Connection error: kex error : no match for method kex algos: *server [curve25519-sha256,[email protected],ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group16-sha512,diffie-hellman-group18-sha512,diffie-hellman-group14-sha256], client [diffie-hellman-group14-sha1,diffie-hellman-group1-sha1]

Can you add the output of "Program Files\Wireshark\extcap\sshdump.exe" --version

Thanks! oh... I got error about libwsutil.dll, libssh.dll, glib-2.dll....Already reinstall wireshark, do you know how to fix this? "The code execution cannot proceed because libwsutil.dll was not found. Reinstalling the program may fix this problem. "

Try running it from the Wireshark directory:

cd "Program Files\Wireshark"
extcap\sshdump.exe --version

Newer versions of libssh support the kex needed for your server.
There is an open issue (Some Windows packages need updating) for Windows.
The macos version was recently updated

Can you open a new issue on the Gitlab issues for Wireshark that references sshdump on Windows.
