I am trying to understand why Remote Management (vnc) is not working on my iMac. I enable Remote Sharing via GUI on Sharing "Remote Management."
when I request "telnet localhost 5900" I get an answer. when I request "telnet 4-digit-ip 5900" I get no response.
Normally, I would think that my firewall is blocking it, but the firewall is off.
A portscan tells me that 22 (ssh) and 3283 (net assistant), as well as a couple of high ports (like Dropbox) are open, but nothing else.
I tried allowing access for everyone or just for me. I have tried "Anyone may request permission" or not. Are there other plist etc options that need to be switched on, that might have been accidentally turned off?
