Open the remote control and port on the Linuxe server. Intranets can be directly connected with addresses and ports. External network needs to do port mapping.
1. Start the ssh(secureshell) service (mine is linuxubuntu 10. 10). Of course, before starting the ssh service, you need to download the relevant software. Use the following command: sudoapt-getinstallssh, then enter /etc/init.d, and enter the command: sudoservicesshstart to open the ssh service. Use netstat-tln to check whether the ssh service is turned on (ssh service uses 22 ports by default). To turn off the ssh service, use: sudoservicesshstop to turn off the ssh service.
2. Download the ssh client putty in the client (widnows host), fill in the linux server ip, sessionname, save it, open it, enter the user name and password, and log in successfully.
What is Song Seung Heon? How does Linux modify SSH port number?
1
Song Seung Heon is SecureShell.
Developed by NetworkWorkingGroup of IETF;
SSH is a security protocol based on application layer and transport layer.
The data transmitted by SSH is encrypted, which can effectively prevent the transmission process from being intercepted and ensure the security of data.
SSH data is compressed, so it can speed up the transmission.

First, check whether the SSH package has been installed in linux, and use rpm-QA | grepsash.
2. Confirm that the ssh service has been started.
3. Find the SShD _ config file in the /etc/ssh directory.
Edit and modify SSH port numbers
1. Using the VIvim editor, open the file sshd_config and search to find the port field.
2 Set the cursor to yy in port22, then copy a line on the keyboard P, and insert Edit 22 with port 2222.
After setting 3, wq saves and exits, indicating that port number 2222 has been added.
4. Of course, after the setup is completed, you need to restart the SSH service.
5. If you have set a firewall, please modify the rules for adding a firewall, or turn it off directly.
Matters needing attention
By default, SSH port is 22. If you want to modify, edit port 22 directly. Note that the front "#" should be removed, then saved and restarted.
What remote desktop connection is used between linux and linux?
You can connect by ssh command. Command syntax:
1, the specified user: ssh-lroot192.168.0.1or ssh root @192.168.0.1.
2. If the ssh login port has been modified, it can be: ssh-p12333192.168.0.11ssh-lroot-p12333/kloc. 8+092. 1 68.0.11connection steps:1,open the terminal. 2. In general, you can use ssh+ target address. Test the connection with this machine: ssh 127.0.0. 13. When logging in for the first time, you will be prompted to confirm the connection and enter yes. The connection was successful. 4. You need to enter a password to connect to other accounts or computers.
Can ssh only log in to linux?
Ssh is not limited to linux operating system. Ssh is a program used by unix operating system for remote login.
The open source free version of ssh is openssh, which originated from openBSD operating system. After sshd is enabled on the server side, you can log on to the server remotely. At present, all unix-like operating systems run ssh services. So ssh can log in to all unix-like operating systems.
Linux can PING, but SSH cannot connect. How to solve it?
Reason: blocked by firewall, whether the parameters in ssh service configuration file refuse to connect, etc. Solution:
First, open SSH.
Log in to Linux as root, open the terminal and run: /etc/init.d/sshdrestrat.
Second, close the firewall.
1. Run the installer on the terminal.
2. Select the firewall and enter it.
3. Press the tab key to switch to the disabled items, then press the spacebar to select, then press the tab key to switch to ok, and then press the spacebar to select.
4. Press the tab key to switch out, and press the blank key to select. Then log in to Linux with client ssh.
Third, another way to close the firewall. /etc/init.d/iptablesstop .
4. If the ping is different, if linux is installed in Vmware, you need to set the NetworkAdapter as bridging in the virtual machine settings, because it is "NAT" by default.
