Configure the SSH service and use the SecureCRT tool in ubuntu

I am used to this kind of operation because I am usually developed on windows. It is inconvenient to write code in linux. What should I do? So I found a remote login tool SecureCRT, this tool requires the support of the SSH service, which is much safer than the plain text transmission using the TELNET service. SSH is transmitted in ciphertext. How can I configure it. First, back up the built-in Source: sudo cp/etc/apt/sources. list/etc/apt/sources. list_backup and modify the Source: sudo gedit/etc/apt/sources. select a fast source for list, replace the original content, and save. Update the software package list: Click System-Administrator-Update Manger in sequence for sudo apt-get update to install the System updates. Follow the prompts to restart the software package. Install, configure, and enable the ssh service sudo apt-get install openssh-server Ubuntu is installed with openssh-client by default, so it is not installed here. If your system is not installed, use apt-get for installation. Then confirm whether the sshserver has started: ps-e | grep ssh. If only ssh-agent is enabled, the ssh-server has not been started./etc/init is required. d/ssh start. If you see sshd, it indicates that the ssh-server has been started. The ssh-server configuration file is located in/etc/ssh/sshd_config. Here, you can define the SSH service port. The default port is 22. You can define it as another port number. To ensure security, we recommend that you change the port and restart the SSH service: sudo/etc/init. d/ssh resart SecureCRT the Configuration Setting window pops up when I is opened for the first time. You need to enter username/password: LINUX Account password; hostname: IP address 192.168 ....., port 22 is the default port of the SSH service. Other ports can be connected by default. Of course, the premise is that WINDOWS and LINUX can communicate with each other, you can PING each other's IP address. If you don't want to talk about it, refer to my previous blog. Actually, another tool for eclipsecurecrtis putty.exe. If you are interested, you can try it. However, I still use secureCRT. Another feature is serial port debugging, a tool similar to a Super Terminal. I personally think it is better to use it than a Super Terminal. I will not talk about the specific settings, that is, writing a port, if you select baudrate or parity, you can select serial in the pop-up window. The default service is SSH. Now, let's get the environment ready today. If we learn more about technology tomorrow, we feel like LINUX is quite simple. Author: js_gary
