ftp2telegram

ftp2telegram is an FTP server that forwards all uploaded files to preconfigured Telegram contacts. It was developed with the specific goal of retrofitting a Telegram interface into older devices or software that exclusively support FTP upload for file transfer.

Caution: ftp2telegram has not undergone security testing. Avoid exposing it to untrusted networks or the public internet without implementing proper security measures.

• FTP server configuration (ftp):
  • host: Specifies the FTP server's IP address or hostname.
  • port: Specifies the FTP server's port.
• Telegram configuration (telegram):
  • token: Replace MY_TOKEN with the actual token of your Telegram bot. Create one using BotFather.
• User configuration (users):
  • Each user in the list is defined by:
    • name: The username for FTP server authentication.
    • hashed_password: The SHA512-hashed password of the FTP user. Generate a hashed password using openssl passwd -6.
    • telegram_id: The Telegram user ID associated with the FTP user. Obtain it using bots such as @userinfobot.

Usage

Run the server:

ftp2telegram

File Upload

Log into the server using any of the configured user credentials, and then upload a file. The uploaded file will be automatically sent to the Telegram user linked to the corresponding FTP user in the config file.

Caveats

• There are no subfolders on the FTP server, nor does it allow the creation of any. Thus, all files must be directly uploaded to the root directory.
• Using interactive FTP browsers to access the server may result in errors, as they are restricted from reading the contents of the root directory.
• Since Telegram bots cannot initiate conversations with users, recipients must add the bot and send them a message first before they can receive any files from the bot.
