Solution 1
Edit the /etc/ssh/ssh_config file using the following command
sudo vi /etc/ssh/ssh_config
Commentout the following lines
GSSAPIAuthentication yes
GSSAPIDelegateCredentials no
save the file and exit
Solution 2
If you got to System>Administration>Network
Now you should see similar to following screen here click the “General” tab
You need to Uncheck the option that says “Scan for available services and advertise . . .” and close
Now you can try to login using ssh you should see it will prompt for password immediately

Thanks for the tip! I was wondering what was causing this. I went with Solution #2.

Are the two solutions doing the same thing? Should I follow both of them for additional security?

Sorry. None of the two medications did solve the problem on neither of my two computers.

Yeah, this didn’t work for me either. I still have to wait 10-15 seconds for it to ask for a password. This is on my local network behind my firewall.

I finally got this fixed with a slightly different approach.

Added that config to the client and all is good now.

You can also speed it up with a UseDNS no in sshd_config. (OpenSSH FAQ)
