krdc вміє зачепитись до будь-якого порту. Як, власне, й інші vnc-клієнти. Якщо там справді VNC-протокол, без «покращення» то воно буде працювати завжди.
What type of information does Intel® Active Management Technology (Intel® AMT) send across the network?Intel AMT sends and receives data over predefined IANA network ports: port 16992 for SOAP/HTTP, port 16993 for SOAP/HTTPS, port 16994 for Redirection/TCP, and port 16995 for Redirection/TLS. DASH compliant systems will send and receive data over ports 623 for HTTP and 664 for HTTPS. The Keyboard-video-mouse (KVM) session can run either over the above redirection ports (16994 or 16995) or over the customary RFB (VNC Server) port - 5900. The type of information sent over the network includes Intel AMT command and response messages, redirection traffic, and system alerts. Data transmitted over ports 16993 and 16995 is protected with Transport-Layer Security (TLS) if that option is enabled on the user's system.Intel AMT may send data over either an IPV4 or IPV6 network and is compliant with RFC 3041 privacy extensions.
