The XDMCP server is set up with XDMCP enabled (listens for connections - UDP port 117) Someone starts an X server, and either implicitly or explicitly either queries a specific XDMCP server, or broadcasts to ask whether there are any XDMCP servers on the subnet. The XDMCP server accepts the connection, or notices the broadcast. The X Display Manager Control Protocol uses UDP port 177. An X server requests that a display manager start a session by sending a Query packet.

Each must have a matching UDP port number in the X-Deep/32 XDMCP UDP Port parameter. PC. Once X-Deep/32 is installed on the PC, it must be configured to connect to Host. The X-Server Menu option gives access to X-Server Options. XDMCP is primarily useful for running thin clients such as in terminal labs. Those thin clients will only ever need the network to access the server, and so it seems like the best security policy to have those thin clients on a separate network that cannot be accessed by … # XDMCP Server configuration # # enabled = True if XDMCP connections should be allowed # port = UDP/IP port to listen for connections on # key = Authentication key to use for XDM-AUTHENTICATION-1 or blank to not use authentication (stored in keys.conf) # # The authentication key is a 56 bit DES key specified in hex as 0xnnnnnnnnnnnnnn What Ports Need to be Opened for XDMCP X-Win32 can connect to linux hosts even behind a firewall.

Our probe tests to see if the X Display Manager is accessible by sending a “Query” packet to the XDMCP port (177/UDP) and listening for the responses. The responses received are typically either of the “Willing” type, which means that the X Display Manager is willing to provide service, or the “Unwilling” type, which means that the

The host PC is running xdmcp on CentOS 5. The user PC (laptop) is running also running CentOS 5. I've not seen it mentioned anywhere, but you have to explicitly open ports 177 (udp) and 6000-6005 (tcp) to get xdmcp to work. Hi, I need to disable XDMCP port in HPUX 11.31.

As an example, one could configure a rule with iptables that matches via source ports, e.g.: This is an update on my hard-fought attempt to run xdmcp on CentOS. I'm continuing to experiment with my two computer network. The host PC is running xdmcp on CentOS 5. The user PC (laptop) is running also running CentOS 5. I've not seen it mentioned anywhere, but you have to explicitly open ports 177 (udp) and 6000-6005 (tcp) to get xdmcp to work. This is a list of TCP and UDP port numbers used by protocols of the Internet protocol suite for operation of network applications.

Hi, I need to disable XDMCP port in HPUX 11.31. I read through the forum and someone here suggested to: 1) /usr/dt/config/Xconfig to /etc/dt/config/Xconfig 2) then uncommon: Dtlogin.requestPort: 0 As for my server, I don't have /usr/dt/config/Xconfig and my /etc/dt/config/Xconfig is empty. So I The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the well-known ports.
