Undocumented Features

1. Ftp :
- FTP connections (in the "non-Passive", default, mode) may be made through an 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 the remote host (say, 192.168.136.41) via FTP, and SSH connection is made with the SSH daemon which is on another remote host (say, 192.168.136.34), and each host is directly accessible one from another (192.168.136.41 <-> 192.168.136.34).
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 192.168.136.34). At first, two forwardings must be made via SSH-Client facility. Local-to-Remote: "21->192.168.136.41/21" (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=192.168.136.34" and "PORT_SSH_FWD=5555,4444" (i.e., set the remote and local ports).
Now the FTP may be started. The "host" field must contain "localhost" or "127.0.0.1". The "non-Passive" mode must be set up (i.e. the "Passive Transfer" check box is unchecked).
After "Connect" the FTP will be connected with "192.168.136.41" without any direct network access (only via SSH connection).

2. NFS-Server :
- the "AUTO_CHECK_ExPortmapper=1" line can be inserted into the "[NFSSERVER]" section of the xwp.ini file to check whether an external portmapper exists to use it;

3. NFS-Client for Windows NT4/2000/XP :
- the size of network packets may be changed instead of using the fixed 8K value;
- the full set of settings may be saved to a file and loaded from it later.

4. Startup :
- to input any text into the command line before its executing, the "$(INPUTLIP)" macros may be used.
E.g. if the "Command" field contains the following line:
"xterm -display $(INPUTLIP):0" then you will be prompted to input the text string (an IP address is assumed).
If you enter "1.2.3.4", then the resulting command line will be: xterm -display 1.2.3.4:0 .
- the "Telnet_SSH/SSH2 (SSH-2 Client)" Start Method is similar to other methods except for the ending of command line. The usage of the "&" sign is not recommended because of unstable results.
E.g., if you need to start "xterm" remotely, then the "xterm" command line is preferable (and the "xterm&" line is not recommended).

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 .

3. NFS-Server :
- may have problems on PCs with several IP addresses;
- some Linux NFS-3 Clients may issue an error message (about the wrong file ID) because of wrong packets unwrapping in the Linux's "nfs3xdr.c" module.

4. NFS-Client for Windows 9x :
- PC must be restarted after you change the license file, "xwpdllid.dll";
- may fail when connecting to NFS-Server on another PC under Windows 9x if both PCs have Client/Server for Microsoft Networks installed.
