Many friends don't know the difference between HTTP proxy. In fact, they use different protocols. HTTP proxy can proxy client's HTTP access, while SOCKS proxy simply transmits data packets and doesn't care about the application protocol. HTTP proxy can be tested through the browser settings, but the socks5 proxy cannot be tested directly through the browser proxy, so how should the socks proxy be tested? Today I will teach you a few simple test methods.
1. Test by curl command
1 Windows computer can use win+r, then enter cmd to run and open the cmd console. After opening, get the ip and port of the cocks proxy you need to test. For example, my test ip and port are: 114.57.217.62:32458, then Just enter the curl command and press Enter, as shown in the figure below (the request address is the actual ip address for query):
2 "Terminal" needs to be opened on the mac computer, the operation is the same
2. Test through the agent of QQ, the operation steps are as follows:
1. Open the QQ application and find the QQ login settings button
2. Choose SOCKS5 proxy
3. Fill in the proxy ip and port you need to test into the corresponding input box, and click Test.
Note: QQ needs to use the UDP protocol to transmit data, so you need to know whether the tested SOCKS5 proxy supports the UDP protocol during the test. If it does not support the test, a failed popup will pop up. The current streaming proxy is not supported, please pay attention when using it.
Three, through the Firefox browser
Most browsers need to use third-party plug-ins to support the use of socks5 proxy, which will be more troublesome. Firefox browser can directly support socks5 proxy settings for testing, but it does not support username + password authentication mode.
