ProFTP Version 2.4 - FTP client

Date: May 9, 2005

Labtam is pleased to present a new software version for ProFTP now - Version 2.4. It is our first major release for the 2005 year.

ProFTP is a file transfer program which allows you to transfer files between your PC and a remote computer using the ARPANET standard File Transfer Protocol. The program can transfer files in two different format types: ASCII format is used for text files, and Binary format is used for image files.

FTP must run on a machine that is configured for TCP/IP network communication or Internet access. Access can be gained through Winsock and the use of any dial-up provider, a Remote Access Server (RAS), or a direct connection via a local area network that supports TCP/IP. In order for FTP to communicate with a remote computer, that computer must have a server implementation of FTP (FTP server based on TCP/IP transports).

You can be connected to only one remote computer at a time during a FTP session. However, you can run multiple FTP sessions (FTP clients) simultaneously in separate windows, with each session connected to a different host.

New Features on this release include:

1. FTP:
- FTP can copy files with illegal symbols using a map table.

2. Telnet:
- implemented the "-mout [<outputfile>]" command-line option to provide a "readable" log-file for the session;
- implemented the "-lxdn [<DisplayNumber>]" command-line option to set the "DISPLAY" session environment variable if a remote daemon supports it (the "-lxdn" option means lookup running the XServer);
- Telnet understands the local XServer's "DynamicDisplayNumber" mode and correctly looks for running the XServer.

The following bugs have been fixed:

1. Installation:
- the silent installation did not correctly use some saved installation parameters (i.e. the "Destination directory").

2. Telnet:
- more correct restarting to remove a possible "restart loop" and crash after the "password->"Disconnect" action.

Undocumented Features

1. Comsetup:
- implemented the "Auto-start XwpPeg Package Watcher" setting to provide the corresponding control of the XwpPeg facility.

2. Ftp:
- FTP connections (in the "non-Passive", default, mode) can be made through an existing SSH connection with prepared Forwarded ports. This way does not require a special Telnet/SSH facility and can be used with any SSH-client which provides traditional Forwarding. All settings are made manually. Let's assume that you need to access the remote host (say, via FTP, and SSH connection is made with the SSH daemon which is on another remote host (say,, and each host is directly accessible one from another ( <-> Also, you should know two free ports on local machine (say, 21 and 4444) and one on the remote host connected via SSH (say, 5555 on At first, two forwardings must be made via SSH-Client facility. Local-to-Remote: "21->" (that in natural for FTP) and Remote-to-Local Forwarding: "4444<-5555". After that you must add two lines to the "[FTP]" section in the "xwp.ini" file: "IP_SSH_FWD=" and "PORT_SSH_FWD=5555,4444" (i.e., specify the remote and local ports). Now the FTP can be started. The "host" field must contain "localhost" or "". The "non-Passive" mode must be set up (i.e. the "Passive Transfer" check box must be unchecked). After "Connect" the FTP will be connected to "" with no direct network access (only via SSH connection).

Known problems

1. Uninstallation: - the uninstallation procedure does not remove components which were installed in additional (non-first) installation sessions. Such additional components should be removed manually.

2. Lpd: - printers on the remote MS Windows NT 4 hosts are unavailable from the local host under MS Windows NT 4.

Single User licenses are at $20.00 USD. Please visit the Software Pricing page for pricing on Multiple Licenses.
