https://www.vps-mart.com/blog/how-to-connect-to-ubuntu-linux-with-ssh-keys-using-putty-from-windows https://documentation.help/PuTTY/plink-usage.html Introduction It is generally recommended to use SSH key authentication whenever possible, especially for servers or systems accessible over the internet. This is because SSH key authentication is based on asymmetric cryptography and is considered more secure than password authentication. It provides stronger protection against brute-force attacks, as the private key is typically much longer and harder to guess than a password. SSH key authentication can also be automated, allowing for passwordless logins and easier integration with scripts and automated processes. Additionally, The private key can be protected with a passphrase, adding an extra layer of security. In the tutorial, we will show you how to connect to Ubuntu Linux VPS with SSH keys using puTTy from Windows.   Prerequisites   Verify Your Remote Linux Server is Ready

Remote SSH to Ubuntu Client using C#

To convert the given C++ code into .NET C# code for remotely rebooting an Ubuntu machine from a Windows application, here's how you can do it: C# Code: using System; using System.Diagnostics; namespace RemoteReboot {     class Program     {         static void Main(string[] args)         {             string remoteHost = "your-ubuntu-ip";             string username = "your-username";             string password = "your-password"; // Ideally, use key-based authentication for better security             string command = "sudo reboot";             ExecuteRemoteCommand(remoteHost, username, password, command);         }         static void ExecuteRemoteCommand(string host, string user, string pass, string command)         {             Process process = new Process();             process.StartInfo.FileName = "plink.exe"; // Path to plink.exe             process.StartInfo.Arguments = $"-ssh {user}@{host} -pw {pass} \"{command}

Master Clock Time Protocols

Imej
  The information you've provided relates to the features and capabilities of a master clock device, often used in various applications such as telecommunications, broadcasting, and IT infrastructure. This master clock typically provides highly accurate time synchronization to client devices in a network. TIME Protocol (RFC 868) Protocol: TCP/UDP Port: 37 Purpose: The TIME protocol is a simple way for a client to request the current time from a server. The server responds with a 32-bit binary number representing the number of seconds since midnight (00:00) on January 1, 1900 (UTC). This protocol is now considered outdated but is still occasionally used for simple time synchronization needs. DAYTIME Protocol (RFC 867) Protocol: TCP/UDP Port: 13 Purpose: The DAYTIME protocol allows a client to request the current date and time in a human-readable format from a server. The server responds with an ASCII string representing the current date and time. Like the TIME protocol, DAYTIM
