Step-by-step guide on how to connect to servers in Taiwan for testing and speed testing

This article is aimed at technicians who need to remotely manage or verify the network performance of servers in Taiwan. It provides a systematic explanation of the connection process and common speed testing methods, emphasizing practical steps and security considerations to facilitate replication in real-world environments.

Understood Taiwan server The network performance is crucial for service deployment, CDN strategies, or cross-border applications. Through actual connections and measurements, latency, bandwidth, and packet loss can be evaluated to help optimize the architecture and improve the user experience.

Before starting the connection, verify the server IP, login credentials, and target port ； Check whether the local network outbound IP is allowed ； Back up critical configurations and ensure there are emergency recovery plans to reduce operational risks.

Ask the administrator for the public IP address, username, authentication method (password or key), and necessary permissions. It is best to use key authentication and restrict account permissions to follow the principle of least privilege, in order to avoid unnecessary risks.

Check the server firewall rules and cloud platform security groups to ensure that the ports used for remote management and speed testing (such as 22, 3389, or custom ports) are open. Also confirm that the company’s export is allowed to access the target IP.

Linux systems commonly use SSH connections, while Windows commonly uses RDP. After selecting the appropriate method, prioritize using encrypted channels and key authentication to avoid transmitting sensitive information in plaintext over insecure networks.

After connecting via ssh user@ip or by specifying a key, commands such as top, htop, netstat, ss, and iftop can be used to view process and network status. Enable log collection when necessary for subsequent analysis.

When using Remote Desktop, choose a strong password and enable Network Level Authentication (NLA). In public network scenarios, it is recommended to use a jump server or VPN tunnel for access to reduce exposure risks and log connection activities.

Performance testing should cover latency, packet loss, bandwidth, and path analysis. A comprehensive view can be obtained by combining different tools: Ping/traceroute to measure the path, iperf to measure bandwidth, speedtest-cli to actually measure throughput.

Use ping to measure round-trip latency and packet loss rate; conduct multiple tests in succession to observe jitter ； Use traceroute or mtr to analyze latency at intermediate nodes, and identify bottlenecks or abnormal hops.

Deploy the iperf3 server and use it locally as a client for two-way bandwidth testing, paying attention to the impact of concurrent threads and testing duration. speedtest-cli can be used to compare results with public speed testing services.

Connections and testing must comply with local laws and service agreements to avoid unauthorized penetration testing. Log operation records, restrict access times and sources, and close temporarily opened ports after completion.

To connect to servers in Taiwan for testing and speed testing, it is necessary to prepare in advance and manage permissions properly. Select appropriate tools to measure network metrics one by one, and continuously optimize through security policies and log analysis. Regular retesting is needed to keep track of network changes.
