Overview of the Secure Shell Protocol<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>SSH (Secure Shell) is a network protocol that allows users to access and manage remote servers securely. This protocol uses encryption to protect transmitted information, ensuring security for the connection. SSH was developed in the mid-1990s, aiming to replace insecure connection methods like Telnet.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"History_and_Development_of_SSH\"><\/span>History and Development of SSH<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>SSH was founded by Tatu Yl\u00f6nen in 1995 when he recognized the threat posed by insecure connection methods being used by businesses. Since then, SSH has quickly become a popular standard in server management and connectivity.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Advantages_of_Using_SSH_Compared_to_Other_Remote_Connection_Methods\"><\/span>Advantages of Using SSH Compared to Other Remote Connection Methods<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>SSH offers several significant advantages over older applications like Telnet, including:<\/p>\n<ul>\n<li>**High Security**: All transmitted data is encrypted, preventing outside attacks.<\/li>\n<li>**Enhanced Authentication**: It supports public key authentication, allowing users to verify identity more securely.<\/li>\n<li>**Flexibility**: SSH supports various operating systems and can be integrated with many tools and applications.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"How_Does_SSH_Work\"><\/span>How Does SSH Work?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>When a user wants to connect to a server via SSH, a connection request is sent to the remote server. The server responds, and both parties perform an authentication process before granting access. All information is encrypted during this process.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Why_Should_You_Use_SSH_to_Connect_Remotely_to_a_Server\"><\/span>Why Should You Use SSH to Connect Remotely to a Server?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Security_Data_Encryption_and_User_Authentication\"><\/span>Security: Data Encryption and User Authentication<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Using SSH ensures that all information sent and received is secure through encryption.

You can check the SSH service status with the command <strong>systemctl status ssh<\/strong>.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Identify_the_IP_Address_and_SSH_Port_of_the_Server_default_is_22\"><\/span>Identify the IP Address and SSH Port of the Server (default is 22)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>After confirming that the SSH server is running, you need to know the IP address and port in use. The default port is usually 22 but can be configured differently for security reasons.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Install_SSH_Client_on_Your_Computer\"><\/span>Install SSH Client on Your Computer<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Install an SSH Client, for example, PuTTY for Windows or use OpenSSH for Linux.

The public key will be uploaded to the server, while the private key remains safely on your machine.<\/p>\n<h4>Copy the Public Key to the Server<\/h4>\n<p>Use the command <strong>ssh-copy-id username@server_ip<\/strong> to copy the public key to the server.<\/p>\n<h4>Configure the SSH Client to Use the Private Key for Authentication<\/h4>\n<p>When opening the SSH Client, specify the private key for connection by going to SSH > Auth and selecting the Private Key file.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Advanced_SSH_Configuration_to_Enhance_Security\"><\/span>Advanced SSH Configuration to Enhance Security<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Change_the_Default_SSH_Port\"><\/span>Change the Default SSH Port<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>This way, you will reduce the risk of brute-force attacks by changing the port that SSH uses.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Disable_Password_Authentication\"><\/span>Disable Password Authentication<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Encourage the use of Public Key Authentication and disable password authentication to improve security.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Use_a_Firewall_to_Limit_SSH_Access\"><\/span>Use a Firewall to Limit SSH Access<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Configure the firewall to only allow trusted IP addresses to access the SSH port.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Regularly_Update_SSH\"><\/span>Regularly Update SSH<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Always update to the latest version to avoid known security vulnerabilities.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Troubleshooting_Common_SSH_Connection_Issues\"><\/span>Troubleshooting Common SSH Connection Issues<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3> <font color=\"blue\">If you need assistance, please contact us right away<\/font><\/br><br \/>\n<b>IT SYSTEMS VIETNAM CO., LTD<\/b><br \/>\n<\/br><i>IT Solutions \u2013 Your Business IT Department<\/i><br \/>\n<\/br>HOTLINE: <b>0283 9950 359<\/b><br \/>\n <\/br>Email: <a href=\"mailto:contact@itsystems.com.vn\">contact@itsystems.com.vn <\/a><br \/>\n<\/br>Website: <a href=https:\/\/itsystems.vn\/en\/>https:\/\/itsystems.vn\/<\/a><br \/>\n <\/br>Facebook: <a href=https:\/\/www.facebook.com\/ITSystems.VIETNAM>https:\/\/www.facebook.com\/ITSystems.VIETNAM<\/a><br \/>\n <\/br>Youtube: <a href=https:\/\/www.youtube.com\/@ITSYSTEMS>https:\/\/www.youtube.com\/@ITSYSTEMS<\/a><\/p>\n<p> <\/br><b>HCM: <\/b>2nd Floor, 184\/1A Le Van Sy Street, Ward 10, Phu Nhuan District, Ho Chi Minh City, Vietnam<br \/>\n<\/br><b>HCM: <\/b>321\/10 Phan Dinh Phung Street, Ward 15, Phu Nhuan District, Ho Chi Minh City, Vietnam.<br \/>\n <\/br><b>Hanoi: <\/b>House No. 22, Garden Villa Area, Vinh Hoang Urban Area, 431 Tam Trinh Street, Hoang Mai District, Hanoi, Vietnam.<br \/>\n <\/br><b>B\u00ecnh D\u01b0\u01a1ng: <\/b>Binh Duong Boulevard, Phu Hoa Ward, Thu Dau Mot City, Binh Duong Province, Vietnam<br \/>\n<!-- its-deep-aio-en-related-2026-07-27 --><\/p>\n<section class=\"its-deep-aio-related\" aria-label=\"Related IT Systems services\">\n<h2>Related services from IT Systems<\/h2>\n<p>If your team is dealing with this issue in a live business environment, these services can help you move from diagnosis to a stable operating process.<\/p>\n<ul>\n<li><a href=\"https:\/\/itsystems.vn\/en\/microsoft-business-licensing\/microsoft-windows-licensing\/\">Windows licensing for business<\/a><\/li>\n<li><a href=\"https:\/\/itsystems.vn\/en\/microsoft-business-licensing\/windows-license-pricing\/\">Windows license pricing<\/a><\/li>\n<li><a href=\"https:\/\/itsystems.vn\/en\/it-services-for-businesses\/it-support-services\/\">IT support services<\/a><\/li>\n<\/ul>\n<\/section>\n<p><!-- its-deep-aio-en-faq-2026-07-27 --><\/p>\n<section class=\"its-deep-aio-faq\" aria-label=\"Frequently asked questions\">\n<h2>FAQ<\/h2>\n<h3>When should a business ask IT Systems for support?<\/h3>\n<p>Ask for support when the issue affects users, business data, security, licensing compliance, service availability or daily operations.
