The ProFTP 1.5/Release:20011007 Installation

To install the package, run the "setup.exe" file .

the Windows NT/2000 LPR printer driver is installed manually
by running the "lprd.exe" self-extracting archive file.

ProFTP distributive.

Major differences from the 1.4/Release:20010419 version

1. The following enhancements have been made :

1. FTP :
- FTP connections may be done through existing SSH connection.
In FTP's "Passive" mode the "Dynamic Forwarding", the new Telnet/SSH
feature, may be used.
In FTP's "non-Passive", default, mode the usual Telnet/SSH Forwarding
feature may be used.

2. LPD :
- the listening LPD port is tunable now.
User may set any value instead of standard port 515.

2. The following bugs have been fixed :

1. FTP :
- FTP crashed under Windows 2000;
- else some FTP-servers are recognized and their listings
are viewed correctly.

Major differences 1.4/Release:20010419 from 1.3/Release:20001006 version

1. The following enhancements have been made :

1. Lpd :
- MS Windows 2000 Lpr may send first an extremely large data length
that practically may never be reached. Then it sends the actual data
and finally just closes the connection. New LPD processes correctly
such a case.

2. Ftp :
- works correctly with the bison FTP daemon;
- works correctly with the MS Windows 2000 FTP(Unix-mode) daemon.

3. Xwppeg :
- this utility was implemented to provide the maintenance
of multi-users licenses.

4. The run-time "User's Manual" was renovated.

2. The following bugs have been fixed :

1. Ftp :
- the bug of directory listing for AIX 4.3.3 was fixed;
- Ftp could not parse a directory if a file name had an
apostrophe (or some other special characters).

2. Install :
- the "Variable is not large enough for string variable" message
took place during installation procedure.

Undocumented Features

1. Ftp :
- Ftp has the "-xini" startup command line option from now;
- FTP connections(in "Passive" mode) may be done through existing
SSH connection using "Dynamic Forwarding" - new Telnet/SSH feature.
To do this you must check-on the "Use SSH-1 Connection" check box.
After this the pressing on "Connection" buttons will start
an additional dialog box with list of actual SSH connections(via
Telnet/SSH only). Choose one of the existing SSH connections
from the viewing list and press the "OK" button.
The "Refresh" button is used to renovate the viewing list of current
SSH connections (via Telnet/SSH only);
- FTP connections(in "non-Passive", default, mode) may be done through
existing SSH connection with prepared Forwarded ports.
This way does not require especial Telnet/SSH facility and may be used
with any SSH-client which provide traditional Forwarding.
All settings are made manually.
Let's assume that you need to access via FTP the remote host
(say, and SSH connection is made with SSH daemon
which is on another remote host(say, and each host
is directly accessible from another ( <->
You must know also two free ports on local machine(say, 21 and 4444)
one on remote host, connected via SSH(say, 5555 on
At first, two forwardings must be made via SSH-Client facility.
Local-to-Remote: "21->" (what in natural for FTP)
and Remote-to-Local Forwarding: "4444<-5555".
After that you must add two lines to "[FTP]" section of "xwp.ini" file:
"IP_SSH_FWD=" and "PORT_SSH_FWD=5555,4444" (i.e. set
the remote and local ports).
Now the FTP may be start. The field "host" must contain "localhost"
or "". The mode "non-Passive" must be set(i.e.
the "Passive Transfer" check box is unchecked).
After "Connect" the FTP will be connected with ""
without any direct network access (only via SSH connection).

2. Telnet :
- four new keyboard definitions (Polish,Rus,RusAlt,Finnish) were added.

6. LPD :
- to set new value for LPD listening port,
the "WaitPort=..." line must be added
to the "[LPDAEMON]" section of "xwp.ini" file.
E.g., the "WaitPort=123" sets the LPD wait port to the "123" value.

Known problems

1. Lpd :
- printers on the remote Windows NT 4 hosts
are unavailable from the local host with Windows NT 4 .

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

The programs associated in this package may send and/or receive broadcast IP
requests. Since such packets cannot cross the nearest

We assume that such behavior cannot be considered as "Hacking"
or "Trojan horse's action".
