CentOS NAT mode networking and secureCRT remote login management tool

In the past few days, I have been typing code at work during the day, and at night I have gone home to tinker with the CentOS Internet access under the virtual machine, as well as the configuration of the secureCRT remote management tool. I finally got it all done today and took notes.

I am using NAT mode, configuring a static address, as well as Bridgebridge mode and Host-only host mode. There are many differences between the three modes on the Internet, but I think the NAT mode is closer to real-life use.

The first step is to "Edit"->"Virtual NetworkEditor" in the VMware menu bar. The NAT mode uses the VMnet8 virtual network card. I put the subnet IP address Set it to 192.168.22.0, as shown in the figure:

The second step is to set the IP address of VMnet8 to 192.168.22.X in the change network adapter settings in Windows. Within the network segment, as shown in the figure:

Step 3: Set the IP address in CentOS. I set it to 192.168.22.3, the gateway is 192.168.22.2, BOOTPROTO= static represents the static address

The command to enter the setting is: vi /etc/sysconfig/network-scripts/ifcfg-eth0

Setup completed To restart the network card, the command is: service network restart

Step 4: Open the CentOS terminal and test whether the network is connected:

Or use Firefox browser to open the webpage for testing:

##Okay, here, the virtual machine NAT mode Internet access has been completed. The next step is secureCRT

Remote login

The first step is to enter the CRT and enter the host name and user name in the menu bar "File"->"Quick Connection" :

The second step is to enter the username and password, which is the password to log in to CentOS:

The third step is to Login successful

If the root

user logs in, it is the same, just change the user name and password, and then log in

In this way, you can remotely control the virtual machine under Windows.

It was not successful before. The possible reason is that the VMnet8 virtual network card and CentOS are not in the same network segment, so secureCRT cannot connect. The underlying reason is also my own understanding of the NAT mode. I am not very familiar with and understand them. I will configure them all today and continue to learn about

Linux later.
