author's server has two Ethernet cards, which are set in eth0 and eth1 respectively during core activation. These two cards are SN2000 ISA adapter cards without jumping feet, and most Linux systems recognize these two cards. The initialization steps of the author's Ethernet network are set in rc. inet1. The command is as follows: IPADDR = "207.175.253.15" # Change to the IP address of your cable modem. NETMASK = "255.255.255.0" # Change to your netwo

Linux Shell script automatically modifies the IP address and the ip address of the linuxshell script As a LinuxSA, scripts are used in routine O M, while static ip addresses or MAC binding are used for server ip addresses. Of course, the latter operations are relatively cumbersome, in the former, we can set the host name, ip address information, gateway, and other configurations. Modification to a specific host name is also convenient for maintenance and management. The following script is used

I would like to ask you a question about linux Static Routing-Linux Enterprise Application-Linux server application. The following is a detailed description. When I was learning linux Static Routing, I encountered this problem: In the Redhat9.0 environment, set the specified CIDR Block route (1) The online references are as follows: # Route add-net 192.168.3.0 netmask 255.255.255.0 gw 192.168.6.66 (2) The books on hand are written as follo

The network configuration commands under Linux include Ifconfig, route, where ifconfig is used to view and configure the network interface information, including the IP address, mask, etc. of the network interface. The route is typically used to manage routing information in the Linux kernel. Its greatest purpose is to set static routing table entries. Usually is in the system with Ifconfig configuration network interface, use it to set the host or the IP address of a network segment should be s

10. Address Translation (NAT) The NAT configuration of a firewall is basically the same as the NAT configuration of a router, and it must first define the internal IP address group for NAT conversion, and then define the internal network segment. The command that defines the internal address group for NAT conversion is NAT, which is in the format: Nat [(If_name)] nat_id local_ip [netmask [Max_conns [Em_limit]]], where If_name is the interface name; na

Configure NIC IP alias under Linux What is an IP alias (IP alias). In the words of Windows, it is to configure multiple IP for a network card. Where to add IP aliases can be useful. Network requirements, multiple IP access testing, specific software needs for multiple IP ... and so on. Here are a few examples of how to use the Ifconfig command to configure an IP alias for a network adapter. Environment: Newly purchased server, just installed Redhat AS4 operating system, only a network card and

network interface, which is a very common tool. For example, we can use this tool to configure the network card IP address, MAC address, mask, broadcast address and so on. It is worth saying that you use Ifconfig to specify the IP address for the network adapter, which is only used for debugging networks, and does not change the system configuration file on the NIC. If you want to fix the IP address of the network interface, there are currently three methods: one is to modify the IP address thr
