| Parameter | Why it matters | Recommended value | |-----------|----------------|-------------------| | Host | Must resolve to a reachable site (often www.google.com works) | www.google.com | | User‑Agent | Some carriers block “unknown” agents | Use a recent Chrome/Firefox UA string | | Connection | keep-alive forces the carrier to keep the tunnel open | keep-alive | | | Must be CRLF ( \r\n ). The app inserts them automatically, but if you edit manually be careful. | — | Pro tip: If you experience “tunnel broken after 30 s”, try adding X-Online-Host: <your‑vps‑hostname> or a Referer header. Different carriers react to different header combos. 4.4 Assemble the .conf File The HTTP Injector config format is simple key/value pairs (INI‑style). Below is a minimal, fully‑functional example you can copy into a plain‑text editor (e.g., Jota Text Editor on Android) and save as myproxy.conf .
# ============================== # HTTP Injector – myproxy.conf # ============================== # 1️⃣ Server (your VPS) HOST = your.vps.ip ; IP or hostname of your remote SSH server PORT = 22 ; SSH port (default 22 – change if you use 2222)
# 3️⃣ Proxy (SOCKS5) Settings SOCKS5 = 127.0.0.1 SOCKS5_PORT = 1080 http proxy injector config file download
A ( *.conf ) simply bundles all the above settings into one text file that the app can import with a single tap. 2️⃣ Where Do Config Files Come From? | Source | Reliability | How to Verify | |--------|-------------|---------------| | Official Provider (your own VPS, a trusted friend, or a reputable paid service) | ★★★★★ | Check SSH key fingerprint, test connection manually ( ssh user@host -p PORT ). | | Free Public Lists (Telegram channels, GitHub repos) | ★★☆☆☆ | Many are outdated, may contain malicious payloads, or expose your IP. Always inspect before use. | | Self‑Generated (recommended) | ★★★★★ | You control every parameter; you can generate the payload with the app’s built‑in editor. | Bottom line: Never download a config file from an unknown source and run it blindly. Treat it like any other executable script. 3️⃣ Prerequisites | Item | Minimum Requirement | |------|----------------------| | Android device | 5.0+ (Lollipop) – newer Android versions work better with the built‑in VPN service. | | HTTP Injector app | Latest version from Google Play ( com.proxy.httpinjector ) or F‑Droid. | | Remote server | Linux VPS (Ubuntu/Debian/CentOS) with OpenSSH (≥ 7.x) and a static IP or dynamic‑DNS hostname. | | SSH credentials | Username + password or public‑key authentication (highly recommended). | | Root (optional) | Not required for the app’s VPN mode; root is only needed if you want system‑wide proxy redirection via iptables. | | Internet connection | Mobile data or Wi‑Fi (the one you intend to tunnel). | 4️⃣ Generating a Config File from Scratch Below is a step‑by‑step workflow that ends with a ready‑to‑import myproxy.conf file. 4.1 Set Up the Remote Server # 1️⃣ Create a non‑root user for the tunnel (e.g., tunneluser) adduser tunneluser # 2️⃣ Add the user to /etc/ssh/sshd_config if you want to disable password logins mkdir -p /home/tunneluser/.ssh chmod 700 /home/tunneluser/.ssh # 3️⃣ Paste your public key (recommended) echo "ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAA..." > /home/tunneluser/.ssh/authorized_keys chmod 600 /home/tunneluser/.ssh/authorized_keys # 4️⃣ Restrict the user to port forwarding only (optional but safer) echo "Match User tunneluser" >> /etc/ssh/sshd_config echo " AllowTcpForwarding yes" >> /etc/ssh/sshd_config echo " X11Forwarding no" >> /etc/ssh/sshd_config echo " PermitTunnel yes" >> /etc/ssh/sshd_config echo " ForceCommand echo 'This account may only be used for port forwarding.'" >> /etc/ssh/sshd_config systemctl restart sshd Result: A clean SSH endpoint that only allows port forwarding. 4.2 Choose a Port‑Forward Scheme | Scheme | Typical Use | Example | |--------|-------------|---------| | Dynamic (SOCKS5) | Apps that support SOCKS proxy (e.g., browsers) | ssh -D 1080 tunneluser@your.vps.ip -p 22 | | Local‑Port Forward | Forward a specific port (e.g., 8080 → 80) | ssh -L 8080:google.com:80 tunneluser@your.vps.ip | | Remote‑Port Forward | Expose a service on the phone to the Internet (rare for mobile) | ssh -R 9000:127.0.0.1:80 tunneluser@your.vps.ip |
# 4️⃣ Payload (HTTP request) PAYLOAD = GET http://www.google.com HTTP/1.1\r\nHost: www.google.com\r\nUser-Agent: Mozilla/5.0 (Linux; Android 10) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/110.0 Mobile Safari/537.36\r\nConnection: keep-alive\r\n\r\n | Parameter | Why it matters | Recommended
All the steps you need to get a working .conf file, import it into the Android HTTP Injector app, and start tunnelling safely. 1️⃣ What is HTTP Injector? | Feature | Description | |---------|-------------| | Purpose | Creates a custom HTTP‑header payload that tricks a mobile network (or Wi‑Fi) into opening a TCP tunnel to a remote server. | | Typical Use‑Cases | Bypassing carrier restrictions, accessing geo‑blocked content, or using a cheap VPS as a personal VPN‑like tunnel. | | Supported Platforms | Android (official app HTTP Injector from the Play Store / F‑Droid), also works on rooted devices with the same binary. | | Core Components | 1. Payload – the HTTP request/response trick. 2. SSH / Proxy Server – the remote endpoint that will forward traffic. 3. Port‑forward / Dynamic‑Port‑Forward – optional, for SOCKS5/HTTPS proxy on the device. |
GET http://www.google.com HTTP/1.1 Host: www.google.com User-Agent: Mozilla/5.0 (Linux; Android 10) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/110.0 Mobile Safari/537.36 Connection: keep-alive Different carriers react to different header combos
# 2️⃣ SSH Authentication USERNAME = tunneluser ; SSH user created on the server PASSWORD = yourPassword ; (optional – leave empty if you use key auth) SSH_KEY = /sdcard/Download/id_rsa ; Path to private key on Android (if you use keys)
# 5️⃣ Misc VPN_MODE = true ; Use Android VPN (no root required) CONNECT_TIMEOUT = 30 ; Seconds before giving up RETRY_COUNT = 3 ; How many reconnection attempts
| Symptom | Likely Cause | Fix | |---------|--------------|-----| | | Carrier blocks the payload. | Change User‑Agent or add a fake X‑Forwarded‑For header. | | SSH auth failed | Wrong password / key mismatch. | Re‑enter credentials; verify the key’s permissions ( chmod 600 ). | | SOCKS5 refused | Local port already in use. | Change SOCKS5_PORT to an unused number (e.g., 1085). | | App crashes | Corrupt config (missing \r\n ). | Re‑create the file with a plain‑text editor; avoid copy‑paste from rich text. | 7️⃣ Security & Privacy Considerations | Issue | Impact | Mitigation | |-------|--------|------------| | Plain‑text password in config | Anyone with file access can read your SSH credentials. | Use **
only needs dynamic forwarding, because the payload creates the tunnel and then hands traffic to the local SOCKS5 port. 4.3 Build the Payload The payload is an HTTP request that exploits carrier‑side proxy behavior. The most common “ HTTP GET ” payload looks like:
