• Target: enter host and port (e.g. example.com:443 or 1.1.1.1:80)
• Common ports: HTTP (80), HTTPS (443), SSH (22), MySQL (3306), Redis (6379)
• Test: verifies the TCP three-way handshake and measures connection setup time
• Nodes: pick specific nodes; defaults to all available nodes
About TCP port connectivity testing智普ai
TCPing performs a TCP three-way handshake to a specific port on your target host from multiple nodes worldwide, measuring whether the port accepts connections and how long the connect takes. Unlike ICMP ping, it directly verifies that an application port (such as 443 or 3306) can actually establish a connection, which is closer to real service availability.agi和ai的区别
It is commonly used to confirm that web, database, or cache service ports are reachable from each region, compare connect latency across regions, and investigate ports made unreachable by a security group or network policy. When the target blocks ICMP, TCPing is a reliable alternative for judging connectivity.豆包下载安装
Frequently asked questions百度ai app
How is TCPing different from regular ping?
Regular ping uses ICMP to test whether a host is online; TCPing does a TCP handshake directly against a port, telling you whether the service on that port can actually accept a connection. When a server drops ICMP but the port is open, only TCPing can detect it.chart gpt
What does a connection timeout mean?
The port may not be listening, may be filtered by a security group or network policy, or the link from that region may be down. Compare across several nodes — if only one region times out, it is usually a regional reachability issue.ai功能在哪下载
Which common ports should I enter?
Enter the service you want to test: HTTP (80), HTTPS (443), SSH (22), MySQL (3306), Redis (6379), and so on. The format is host:port, e.g. example.com:443.豆包下载安装
Why does connect latency differ from ping latency?
TCPing measures the time to complete the TCP three-way handshake, including the round trip plus the server's response, so it is usually slightly higher than raw ICMP RTT. Comparing the same metric across regions is more meaningful than the absolute value.chart gpt
