In any case, iptables is a need for special care to set up something, in the event that the server is not around you, and you rushed to set up to prevent SSH, then wait for the boss scold it, hehe ...The content is written to prevent this from happening, of course, it is very elementary, but the general server is enough:1. First introduce the instructions and related configuration files Start command: Serviceiptablesstart restart command: Serviceiptablesrestart NBSP;NBSP C

segments of different network cards of the same route are different, so special distinction should be made between network cards and network segments. Second, view network card informationuse the ifconfig command to see the name and IP address of the network card , and if the NIC name is not standard eth0 and eth1, vim/etc/udev/ Rules.d/70-persistent-net.rules View and modify the corresponding network card information, and /etc/sysconfig/network-scri

Linux network configuration is basically by modifying several configuration files to achieve, although you can also use Ifconfig to set the IP, with the route to configure the default gateway, with hostname to configure the hostname, but the restart will be lost.The following are the relevant configuration files:/ect/hosts Configure host name and IP address, provide resolution to this machine/etc/resolv.conf config domain name (this domain name takes effect when not resolved within the hosts)/et

packets to the default route defined as 10.1.6.1. The default route basically acts as a catchall for any packet this isn ' t being told to do in the what above. As you can see from the example, there are a lot of results, but the first route is the default route, and the routing table tells the system that if some of the packages do not match the routing records, they are sent to the default route 10.1.6.1. The default route is the place where the packets are not specified Our Example System

inherits from ResourceBundle, the operations on the Properties file are very similar. Therefore, we will only start with the ResourceBundle class to briefly introduce its usage of operating the Properties file. The operation method can be found in the following code: 1 package com.webopenshare.demo.prop.utils; 2 3 import java.util.MissingResourceException; 4 import java.util.ResourceBundle; 5 6 public class PropUtils { 7 8 private static PropUtils _instance = null; 9 10 priv

hostname permanently In man hostname, "The hostname is usually set once at system startup in/etc/rc. d/rc. inet1 or/etc/init. d/boot (normally by reading the contents of a file which contains thehost name, e.g. /etc/hostname ). "RedHat does not contain this file, but is composed of/etc/rc. d/rc. the sysinit script is responsible for setting the system's hostname. it reads the/etc/sysconfig/network text file, and the RedHat hostname is set in this fil
