Change IP address in graphic interface mode in Linux

 

1. Open the command mode of the terminal:

Click application in the upper left corner, click the System Tools drop-down menu, and then click Terminal in the expanded drop-down menu to open a command mode.

2. Find the full path of the command module to be used to solve the "command not found" problem:

In command mode, enter: which netconfig

[Root @ localhost ~] # Which netconfig

Check whether the returned results contain the following information:

/Usr/sbin/netconfig

If any result is returned, you can continue to use two Commands: "which ifconfig" and "which route" to view the path of the ifconfig and route commands, in the past, we used/sbin/ifconfig and/sbin/route as examples;

3. In command mode, enter the command:/usr/sbin/netconfig

In this case, an IP settings window is displayed. You can set it on the keyboard. Enter the IP address, subnet mask (netmask), and gateway, and select OK!

4. After setting, enter/sbin/ifconfig to check whether the setting is successful. If it succeeds, you can see the following in the displayed result:

Eth0 Link encap: Ethernet HWaddr 00: 18: FE: 28: 1C: AA

Inet addr: "ip address" Bcast: broadcast address Mask: Subnet Mask

Inet6 addr: fe80 :: 218: feff: fe28: 1caa/64 Scope: Link

Collisions: 0 txqueuelen: 0

RX bytes: 1274688659 (1.1 GiB) TX bytes: 1274688659 (1.1 GiB)

If the corresponding IP address and subnet mask are set, the problem will be solved!

5. If the problem persists, use Method 2:

Open the terminal command mode and enter: "/sbin/ifconfig eth1 220.195.193.86 (IP address) netmask mask 255.255.255.240 (subnet mask )"

Then enter the second command: "/sbin/route add default gw 211.91.88.129 (GATEWAY )"

Note: The Path in/sbin/ifconfig is the result returned by which ifconfig;

6. test whether the Internet can be accessed: Enter the command ping 202.108.22.5 to check whether any data is returned.
