FTP proxy gateway service


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


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



Inetd mode. Standalone service only.


Daemonise. Detach service from console and run in the background.


Be silenT. Do not log start/stop/accept error records.


Never look for username authentication.


External address. IP address of interface proxy should initiate connections from.  By default system will deside which address to use in accordance with routing table.


Internal address. IP address proxy accepts connections to. By default connection to any interface is accepted. It´s usually unsafe.


Default destination. It's used if targed address is not specified by user.


Port. Port proxy listens for incoming connections. Default is 21.


Log. By default logging is to stdout. If logfile is specified logging is to file. Under Unix, if ´@´ preceeds logfile, syslog is used for logging.


Increase or decrease stack size. You may want to try something like -S8192 if you experience 3proxy crashes.


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