Xshell solve the connection centOs7 Could not connect to '? ? ? '(Port 22): Connection failed.

Encounter Could not connect to '192.168.119.129' (port 22) when connecting centos7 with Xshell:. Connection failed this problem, my solution is as follows:

Step1. Obtain an IP address of centos7

Enter "ip addr" after landing acquire ip address, ip if acquired as follows, indicating that at this time your centsOs7 not yet been assigned an IP address can connect.

At this time, need to enter the command "cd / etc / sysconfig / network-scripts" enter "ls" command into the network-scripts, see the situation shown below:

Enter the command "vi ifcfg-eno16777736" will edit the file last changed yes, press the "esc" key to exit edit mode after the change and then enter ": wq" to save and exit (note the colon).

Restart the virtual machine exit, enter "ip addr" again, the situation will appear as shown:

This shows that you can use "192.168.119.129" this ip connection virtual machine.

This can be used when xShell connect again, if the problem still appears as follows:

Step2: Check the virtual machine to install SSH Server

Input command | after "rpm -qa grep ssh" If the situation appears as shown below explained installed SSH service, this does not occur if the following needs to execute the command "yum yum install openssh-server" installation.
