KnoxProxy routes curl and Python proxy requests through one authenticated gateway -- proxy-user auth, redirects, and pycurl support included.
Use the -x flag to route through KnoxProxy.
curl -x http://USER:PASS@gw.knoxproxy.com:7000 https://httpbin.org/ipAdd country to username.
curl -x http://USER-country-us:PASS@gw.knoxproxy.com:7000 https://httpbin.org/ipUse the SOCKS5 gateway port.
curl --socks5 USER:PASS@gw.knoxproxy.com:7001 https://httpbin.org/ipDebug connection issues.
curl -v -x http://USER:PASS@gw.knoxproxy.com:7000 https://httpbin.org/ipAdd targeting headers.
curl -x http://USER:PASS@gw.knoxproxy.com:7000 \
-H "X-KnoxProxy-Country: de" \
-H "X-KnoxProxy-City: berlin" \
https://httpbin.org/ipVerify your exit IP.
curl -x http://USER:PASS@gw.knoxproxy.com:7000 https://httpbin.org/ipExport http_proxy and https_proxy once, and every curl command in that shell session uses KnoxProxy automatically, without repeating -x on each call.
export http_proxy="http://USER:PASS@gw.knoxproxy.com:7000"
export https_proxy="http://USER:PASS@gw.knoxproxy.com:7000"
curl https://httpbin.org/ipKeep credentials out of the proxy URL by passing them with --proxy-user instead of embedding them directly in -x.
curl -x http://gw.knoxproxy.com:7000 --proxy-user USER:PASS https://httpbin.org/ipAdd -L so curl follows 301 and 302 redirects. Curl resends the same proxy and credentials on every redirect hop by default.
curl -L -x http://USER:PASS@gw.knoxproxy.com:7000 https://httpbin.org/ip#!/bin/bash

print(buffer.getvalue().decode())Each curl invocation gets a fresh IP, the same as a fresh wget call or a new Python requests session. For sticky sessions, add -session-{id} to the username -- the session ID behaves identically whether the request comes from curl, wget, or Python.
| Problem | Fix |
|---|---|
| curl: (56) Proxy CONNECT aborted | Check credentials. URL-encode special characters in password. |
| curl: (7) Failed to connect to proxy | Verify port 7000 (HTTP) or 7001 (SOCKS5). Check firewall. |
| curl: (56) Received HTTP code 407 from proxy after CONNECT | Add -x http://USER:PASS@gw.knoxproxy.com:7000 or --proxy-user USER:PASS, and confirm the username and password match your KnoxProxy dashboard exactly. |
| Requests skip the proxy entirely | Unset NO_PROXY for the session, or remove the target domain from the no_proxy list before running curl. |
| curl: (28) Connection timed out | Increase --connect-timeout and --max-time, and add --retry 3 to handle transient failures. |
| Credentials seem to stop working after a redirect | No fix needed for standard redirects. If a redirect target requires different handling, add -L together with --proxy-anyauth. |
USER-country-de-city-berlin-session-profile07Order matters -- geo flags before the session flag. The session name is free text; use the profile ID so the mapping is self-documenting. Password stays as issued; no flags belong there. HTTP on :7000, SOCKS5 on :7001, same credentials.
Use the --socks5 flag to route curl through SOCKS5: curl --socks5 USER:PASS@gw.knoxproxy.com:7001 https://target.com. Port 7001 is the dedicated KnoxProxy SOCKS5 gateway, separate from the HTTP proxy on port 7000, and like every curl invocation it gets a fresh exit IP unless you add -session-{id} to the username.
Yes, add a line reading proxy = "http://USER:PASS@gw.knoxproxy.com:7000" to your ~/.curlrc file, and every curl command on that machine uses KnoxProxy automatically without the -x flag. This works the same way as exporting http_proxy and https_proxy environment variables, but persists across terminal sessions since it lives in the config file.
Add the -v (verbose) flag to your command: curl -v -x PROXY_URL https://target.com. This prints the full CONNECT tunnel negotiation with the KnoxProxy gateway plus the TLS handshake with the target site, so you can see exactly which step failed if a request does not go through cleanly.
Yes, curl output through KnoxProxy behaves exactly like output from any unproxied request, so standard shell piping works without changes. Run curl -x PROXY -s URL | jq to pipe a JSON response straight into jq for parsing, or chain it into grep, awk, or any other command-line tool the same way.
Set a proxy in curl with the -x flag: curl -x http://USER:PASS@gw.knoxproxy.com:7000 https://target.com. You can also export the http_proxy and https_proxy environment variables so every curl command in that shell session uses the proxy automatically, without repeating -x each time.
Add the -L flag: curl -L -x http://USER:PASS@gw.knoxproxy.com:7000 https://target.com. Curl resends the same proxy and credentials on every redirect hop by default, so following a 301 or 302 redirect needs no extra proxy configuration beyond the -L flag itself, even across multi-hop redirect chains that scrapers commonly encounter on real target sites.
Use --noproxy followed by the domain: curl --noproxy example.com -x http://USER:PASS@gw.knoxproxy.com:7000 https://example.com. This is the curl noproxy option, and it overrides both command-line and environment-variable proxy settings for that domain only, while every other request in the same script or session still routes through KnoxProxy as normal.
Curl is a command-line tool suited to quick tests and shell scripts. Python's requests library, or pycurl for lower-level control, fit better inside longer-running scraping code that needs retries, parsing, and error handling. Both route through the same KnoxProxy gateway with identical credentials.
Yes. Wget reads the same http_proxy and https_proxy environment variables as curl, or accepts them directly: wget -e use_proxy=yes -e http_proxy=http://USER:PASS@gw.knoxproxy.com:7000 https://target.com. The KnoxProxy gateway address, port, and credentials stay identical whether the request comes from curl, wget, or a Python script, so switching tools needs no proxy reconfiguration at all.
Yes. Curl runs the same way in any Linux user shell and needs no root access to use a proxy. Set it per command with -x, or export http_proxy and https_proxy in your shell profile so every curl command in that session routes through KnoxProxy automatically.
Pass the -x flag on that single command: curl -x http://USER:PASS@gw.knoxproxy.com:7000 https://target.com. This sets the KnoxProxy proxy for that command only and does not affect any other curl call in the same terminal session, unlike exporting http_proxy and https_proxy globally, which would route every later command through the proxy too.
A 407 response means the KnoxProxy gateway rejected the request because it never received valid credentials. Add --proxy-user USER:PASS or embed the credentials directly in the -x URL as http://USER:PASS@gw.knoxproxy.com:7000, and double-check that the username and password match your KnoxProxy dashboard exactly, including case, since a small typo triggers the same error.
