sk5 proxy validation: SOCKS5 proxy IP connectivity and protocol validation methods

First, SK5 agent in the end what? First chatter to understand the principle

The SOCKS5 proxy is like an intermediate courier, helping you to change your web request and send it out again. The biggest difference with ordinary HTTP proxies is that it can not only pass web data, but also handle traffic from various programs (such as games, crawlers). As if the ordinary courier can only send small packages, while SK5 can transport a whole truckload of stuff.

Here's the point:Two things must be confirmed with SK5 agentsOne is that this proxy IP can be connected (as if the courier station didn't go out of business), and the other is that the agreement is compliant (the courier has to deliver according to the rules).

Second, 3 minutes to quickly detect the proxy IP dead and alive

First teach you the earth method: open the computer CMD (black window) and enter:

telnet Proxy IP Port Number

If the display shows a black screen with the cursor flashing, it means that theThe channel is open.If the connection fails, change the IP address. If the connection fails, change your IP address, it's quick, but it's like hitting a tire with a hammer and listening to the sound.

Advanced version with online tools to detect: recommended ipipgo official website comes with theProxy connectivity checkerIt's a great way to get the results in seconds. Much more accurate than manual detection, but also automatically recognize the protocol type.

Third, the agreement compliance verification to play so

Some agents look like they can connect, actually use a variety of errors, mostly protocol mismatch. Here to teach a Python verification script:

import socket
sock = socket.socket()
sock.settimeout(5)
try: sock.connect(('proxy IP',port))
    sock.connect((('proxy IP',port)))
    sock.send(b'x05x01x00') send protocol handshake packet
    if sock.recv(2) == b'x05x00'.
        print("SOCKS5 protocol validation successful!")
except Exception as e.
    print("Authentication failed:",e)

This code detects whether the agentSerious support for the SOCKS5 protocol, as in checking if the courier has a work permit.

IV. Practical guide to avoiding pitfalls

Based on our experience in handling 3000+ cases, common problems are solved this way:

Fifth, choose the right service provider less detour

It's too much work to toss the verification yourself, so you might as well just go with a reliable service provider. For exampleSOCKS5 Proxy for ipipgoThere are these advantages:

• Local IP in 200+ countries around the world, no protocol incompatibility issues
• Client comes with protocol detection, eliminating the need for manual verification
• Supports flexible purchasing by hour/day/month, low trial and error cost

QA First Aid Kit

Q: Why does the test pass but not work?

A: 80% of the authentication information is not filled out correctly, check whether the username and password contain special symbols, it is recommended to test in the ipipgo client first!

Q: How do I choose a package for enterprise applications?

A: crawler business with dynamic residential (enterprise version), the need for fixed IP selection of static residential, cross-border business directly on the cross-border dedicated line

Q: Who do I call with technical problems?

A: ipipgo provide 7 × 24 hours technical support, the official website at the bottom right corner at any time point online customer service
