endprotoent - Linux

Overview

endprotoent terminates access to the /etc/protocols file, which contains a list of well-known TCP/IP protocol numbers and their corresponding names. It is primarily used when working with protocol-related information and network communication.

Syntax

endprotoent() -> None

Options/Flags

None.

Examples

Simple usage:

import socket

socket.endprotoent()

Integrating with other commands:

Get the name of a protocol given its number using getprotobynumber and then terminate access:

import socket

proto_num = 6
proto_name = socket.getprotobynumber(proto_num)
socket.endprotoent()

Common Issues

  • Not terminating access to the protocols file can lead to unexpected behavior or performance issues.
  • If endprotoent is not called after accessing the protocols file, subsequent calls to protocol-related functions may fail.

Integration

endprotoent can be used in conjunction with other protocol-related functions from Python’s socket module, such as getprotobynumber, getprotobyname, and inet_ntop.

Related Commands

  • getprotobyname: Retrieves protocol information by name.
  • getprotobynumber: Retrieves protocol information by number.
  • inet_ntop: Converts an IPv4 or IPv6 address to a string.
