For the login to succeed, you (the client) must have access to the corresponding Private Key (again: anyone with access to the Private Key can authenticate the connection). The server has a copy of your Public Key and can use it to authenticate your login request. A Public Key is public: you can distribute it freely to anyone. Interestingly, the same procedure works fine on my recently purchased (two weeks) MacBook Air. On the other hand, ifI just start XQuartz and open an xterm I have no problem, i.e., the DISPLAY variable is set normally. In short, you can create a pair of keys: a Private Key and a Public Key.Īs their name suggests, the Private Key is private: you should treat it like a password. Specifically, the DISPLAY variable does not get set (output of echo DISPLAY is just two blank lines). As soon as you are connected run the following command: 'matlab &' (this will start MATLAB as a background process. Go back to Session tab (the one you have started with) using navigation tree on the left and press 'Open'. Login to the Remote Host and check the DISPLAY. SSH can authenticate connections based on Public Key Infrastrucure (PKI). Navigate to Connection -> SSH -> X11 tab using navigation tree on the left and check 'Enable X11 forwarding' checkbox. X11 Forwarding with SSH Start TeraTerm, click Setup, SSH Forwarding. A reasonable use case is when you are logged-in via VPN to your organization – you can reduce the strength of the underlying cipher because the VPN connection itself is already encrypted. Do not modify ciphers unless you know exactly what you are doing. Tweaking the ciphers can have dramatic security implications.
