To install and use the tcping tool on Ubuntu, follow these steps: 1. **Install Dependencies and Tool**: Update the package list, install `tcptraceroute`, and download the `tcping` script. ```bash sudo apt update sudo apt install tcptraceroute sudo wget http://www.vdberg.org/~richard/tcpping -O /usr/bin/tcping sudo chmod +x /usr/bin/tcping ``` 2. **Basic Usage**: Test the connectivity of a specific port on a target host (default is port 80). ```bash tcping example.com 443 ``` 3. **Common Parameters**: - `-t`: Continuous testing until manually stopped (Ctrl+C). - `-n 5`: Send 5 test requests. - `-i 5`: Set interval time to 5 seconds. - `-w 0.5`: Set timeout to 0.5 seconds. - `-d`: Include date and time in output. - `-4/-6`: Force use of IPv4 or IPv6. 4. **Example**: Test Baidu's port 443, 5 times with a 2-second interval. ```bash tcping -n 5 -i 2 www.baidu.com 443 ``` **Note**: If the target server has ICMP disabled, tcping can still check port status via TCP. Some parameters may vary by version; use `tcping -h` for help. For advanced features, refer to the full documentation.

In the Ubuntu system, you can install and use the tcping tool by following these steps:

1. Install dependencies and tools#

First, you need to install tcptraceroute and download the tcping script:

sudo apt update
sudo apt install tcptraceroute
sudo wget http://www.vdberg.org/~richard/tcpping -O /usr/bin/tcping
sudo chmod +x /usr/bin/tcping

2. Basic usage#

Test the connectivity of a specific port on the target host (default port is 80):

tcping example.com 443  # Test the 443 port of example.com

3. Common parameters#

-t: Continuous testing until manually stopped (Ctrl+C)
-n 5: Send 5 test requests (for example: tcping -n 5 example.com 80)
-i 5: Set the interval time to 5 seconds (for example: tcping -i 5 example.com 80)
-w 0.5: Set the timeout to 0.5 seconds (for example: tcping -w 0.5 example.com 80)
-d: Include date and time in the output
-4/-6: Force the use of IPv4 or IPv6

4. Example#

Test the 443 port of Baidu, 5 times continuously, with an interval of 2 seconds:

tcping -n 5 -i 2 www.baidu.com 443

Notes#

If the target server has disabled the ICMP protocol (such as disabling PING), tcping can still check the port status via TCP protocol.
Some parameters may vary slightly due to different versions; you can view the complete help by using tcping -h.

If you need more detailed output or advanced features such as proxy settings, you can refer to the full documentation.
