The logs at the server are as below 16:28:34 SSL: accept_openssl(OPENSSL_VNC) Saved the certificate received from the remote server into Accepted Certs dir The viewer (vnccert2.pem file) in M圜ert fieldĬlicked Connect with option Use SSL selected Provided the path of the pem file generated in the client system to x11vnc -display :0 -sslverify ~/vnccert2.crt -ssl SAVE.So, I've followed steps for Option 1 i.e., to authenticate VNC Viewer to a VNC Server. The hostname does not match the Common Name. ) that connections will be made to orįrom that will avoid many dialogs when connecting mentioning that Tip: if you choose the "Common Name" to be the internet hostname The first one describes how to use x11vnc to create CertificateĪuthority (CA) certificates in addition to Self-Signed ones. Somebody steals a copy of the "vnccert.pem" file then they can pretendĪfter you have created the certificate files, you must copy and importĮither "vnccert.pem" or "vnccert.pem" to the remote VNC Server andĪlso select the other file in the "SSL Certificates" dialog. Private Key that goes in the "vnccert.pem". The click on "Create" to generate the certificate files.Įncrypting the Private Key: It is a very good idea to encrypt the Then fill in the identification information (Country, State or Province, Then you would use "vnccert.crt" as the as the ServerCert entry in theĬhoose a output filename (ending in. Then you would use "vnccert.pem"Īs the M圜ert entry in the SSL Certificates dialog.įor case 2) you would copy "vnccert.pem" to the VNC Server side and (it is also possible to handle many client certs at once in a directory, X11vnc -sslverify /path/to/vnccert.crt -ssl SAVE. "vnccert.crt"įor case 1) you would copy "vnccert.crt" to the VNC Server side and "vnccert.pem"Ĭontains both the Private Key and the Public Certificate. That file will be generatedīy this process and so will the "vnccert.crt" file. Or you could send it to the system administrator of the VNC Server.įor the purpose of description, assume that the filename selected in the In either case you will need to safely copy one of the generated key orĬertificate files to the remote VNC Server and have the VNC Server use Or 2) your verifying the identity of a remote VNC Server. The resulting certificate files can be used for either:ġ) authenticating yourself (VNC Viewer) to a VNC Server On Windows, a copy of the openssl program is provided for convenience. On Unix the openssl(1) program must be installed and in $PATH. Steps followed This dialog helps you to create a simple Self-Signed SSL certificate. I am able to connect to it without the ssl option but it fails when I use SSL. The remote machine is running ubuntu 16.04 and has x11vnc server installed (v0.9.13). Ive downloaded the Enhanced Tight VNC Viewer ( ) and followed instructions to connect the viewer on my local machine(running Win 7) to another machine running the x11vnc server.
