## NAME

ftppr - FTP proxy gateway service

## SYNOPSIS

ftppr [-d] [-l[[@]logfile]] [-pport] [-iinternal_ip] [-eexternal_ip] [-hdefault_ip[:port]]

## DESCRIPTION

ftppr is FTP gateway service to allow internal users to access external FTP servers.

## OPTIONS

| -I |  | Inetd mode. Standalone service only.
| -d |  | Daemonize. Detach service from console and run in the background.
| -t |  | Be silenT. Do not log start/stop/accept error records.
| -u |  | Never look for username authentication.
| -e |  | External address. IP address of the interface the proxy should initiate connections from. By default, the system will decide which address to use in accordance with the routing table.
| -i |  | Internal address. IP address the proxy accepts connections to. By default, connections to any interface are accepted. It´s usually unsafe. Unix domain sockets can be specified with -iunix:/path/to/socket syntax (e.g., -iunix:/var/run/ftppr.sock). On Linux, abstract sockets use -iunix:@socketname syntax.
| -h |  | Default destination. It’s used if the target address is not specified by the user.
| -p |  | Port. Port proxy listens for incoming connections. Default is 21.
| -l |  | Log. By default logging is to stdout. If logfile is specified logging is to file. Under Unix, if ´@´ precedes logfile, syslog is used for logging.
| -S |  | Increase or decrease stack size. You may want to try something like -S8192 if you experience 3proxy crashes.

## CLIENTS

You can use any FTP client, regardless of FTP proxy support. For a client with FTP proxy support, configure internal_ip and port in the FTP proxy parameters. For clients without FTP proxy support, use internal_ip and port as the FTP server. The address of the real FTP server must be configured as a part of the FTP username. The format for the username is username@server, where server is the address of the FTP server and username is the user´s login on this FTP server. The login itself may contain an ´@´ sign. Only cleartext authentication is currently supported.
