The server site does not have to configure its firewall/NAT to allow access on a defined port; the onus is on the viewer, which is useful if the server site has no computer expertise, while the viewer user would be expected to be more knowledgeable.
The initial versions of the XRDP project relied on a local VNC server installation that had to be present alongside the program, in order to relay the graphics and controls between the user and the server [7] (known as the "VNC forwarding mode"). However, this mode is currently not recommended to use anymore, due to its slow performance.
Mail is read either through direct access (shell login) or mailbox protocols like POP and IMAP. Unix-based MTA software largely acts to enhance or replace the respective system's native MTA. Microsoft Windows servers do not natively implement e-mail, thus Windows-based MTAs have to supply all the necessary aspects of e-mail-related functionality.
A new feature in RDP 8.0 is limited support for RDP session nesting; it only works for Windows 8 and Server 2012 though, Windows 7 and Server 2008 R2 (even with the RDP 8.0 update) do not support this feature. [25] The "shadow" feature from RDP 7, which allowed an administrator to monitor (snoop) on a RDP connection has been removed in RDP 8.
While logging in, if the user logged on to the local system using a Windows Server Domain account, the credentials from the same sign-on can be used to authenticate the remote session. However, this requires Windows Server 2008 to be the terminal server OS, while the client OS is limited to Windows Server 2008, Windows Vista and Windows 7.
The VNC protocol is pixel based. Although this leads to great flexibility (i.e. any type of desktop can be displayed), it is often less efficient than solutions that have a better understanding of the underlying graphic layout like X11 or desktop such as RDP. Those protocols send graphic primitives or high level commands in a simpler form (e.g ...
The original SPICE protocol defined a ticket based authentication scheme using a shared secret. The server would generate an RSA public/private keypair and send its public key to the client. The client would encrypt the ticket (password) with the public key and send the result back to the server, which would decrypt and verify the ticket.
