Guacamole cannot connect via SSH – FIX

If you get “SSH handshake failed” when trying to use Guacamole to connect to Ubuntu via SSH, you need to use a workaround:

In the meantime a workaround is adding “HostKeyAlgorithms +ssh-rsa” to the end of /etc/ssh/sshd_config on the Ubuntu machine and restart sshd. Note: I don’t have an understanding of the security implications of this, so use at your own risk

The solution was posted here:

Check log file for interactive SSH logins

# failed attempt
grep sshd.\*Failed /var/log/auth.log | less

# successful attempts
grep sshd.\*Accepted /var/log/auth.log | less

VMware ESXi

Step 1. Connect to ESXi console and press the Alt+F1 key combination.

Step 2. Type unsupported and then press . Note that nothing will appear on the screen whilst you type this.

Step 3. When prompted enter in the Root password and press.

Step 4. You will now be presented with a prompt on the console. From this prompt type vi /etc/inetd.conf

Step 5. vi (the file editor) has now opened the inetd.conf file. Using the direction arrows scroll through the lines until you reach the line that has #ssh and remove the hash (ie: #). This is effectively un-commenting this line so that the ssh service can be started.

Step 6. Now that you have made this minor file you want to save this change and exit out of the editor (vi). To do this press the ESC key (to put vi back into Command Mode) and then type :wq *Note: If you want to exit without saving any changes to the file then just press the ESC key (Command Mode) and then type :q!.

Step 7. With the SSH service now un-commented from this file we want to restart the
