Hi, I´ve been sitting here all night long trying to get wireshark to connect to the unify dream machine pro via ssh. I can login through all different means (powershell, putty, from other linux server), but wireshark doesn´t work. I can login to other devices via wireshark, but always get errors when I try to login to UDM pro. I´ve also updated libssl and tried Wireshark both on a windows machine, through the linuxserver-docker and a linux-vm.

Here are the logs I get when trying to connect:

 (sshdump:1717) 03:03:07.103846 [Capchild INFO] -- Opening ssh connection to [email protected]:22

Any ideas what the issue can be?

Have you tried capturing a good login (from linux command line) and failed login (sshdump) in Wireshark and comparing the login conversations?

I'm having the same issue. Did you ever find the solution?

This worked for me.

solution is to...

SSH to UDM Pro vi /etc/ssh/sshd_config Change the "PasswordAuthentication no" to "PasswordAuthentication yes" ESC :wq reboot the console
