× Few antiviral products inadequately detect 3proxy as Trojan.Daemonize, Backdoor.Daemonize, etc and many detect 3proxy as a PUA (potentially unwanted program). It may cause browser warning on download page. 3proxy is not trojan or backdoor and contains no functionality except described in documentation. Clear explanation of this fact is given, for example, in Microsoft's article.

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.
