The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. [3] 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 ...
Remote Installation Service utilizes UDP port 4011 [3] to provide clients the contents of each page the OS Chooser displays. Additionally, this service can provide drivers to clients; it is often used to provide the workstation's network card driver, which is required to launch the OS Chooser and mount the share where images are stored.
Linux bonding driver mode that does not require any special network-switch support. The outgoing network packet traffic is distributed according to the current load (computed relative to the speed) on each network interface slave. Incoming traffic is received by one currently designated slave network interface.
NBT exposes information and interfaces that are often appropriate for a LAN under an organization's administrative control, but which are not appropriate for a less trusted network such as the Internet. For example, the NetBIOS Name Service (NBNS), running over UDP or TCP port 137, allows any computer to register its hostname with other computers.
The core functionality of port drivers is mandated by the operating system, and Windows operating systems integrate a variety of port drivers. For example, the i8042prt.sys port driver for the 8042 microcontroller connects PS/2 keyboards to the mainboard peripheral bus. The miniport drivers, like the miniclass drivers, are supplied by the ...
This shows the different programs and their versions, and which ports they use. For example, it shows that NFS is running, both version 2 and 3, and can be reached at TCP port 2049 or UDP port 2049, depending on what transport protocol the client wants to use, and that the mount protocol, both version 1 and 2, is running, and can be reached at UDP port 644 or TCP port 645, depending on what ...
NDIS Miniport drivers can also use Windows Driver Model interfaces to control network hardware. [19] Another driver type is NDIS Intermediate Driver. Intermediate drivers sit in-between the MAC and IP layers and can control all traffic being accepted by the NIC. In practice, intermediate drivers implement both miniport and protocol interfaces.
Computers often have many diverse and customized device drivers running in their operating system (OS) kernel which often contain various bugs and vulnerabilities, making them a target for exploits. [17] Bring Your Own Vulnerable Driver (BYOVD) uses signed, old drivers that contain flaws that allow hackers to insert malicious code into the ...
