ProNFS Version 2.1 - NFS Client and Server by Labtam.

Date: 25 September 2003

Labtam is pleased to present a new software update for ProNFS now Version 2.1.
It is the second major release for the 2003 year.

NFS Client and Server for Microsoft Windows. The only NFS software that gives you the high performance file sharing connectivity capabilities. ProNFS enhances your networking performance and access.

The ProNFS Package can be split into the following:

ProNFS Server

ProNFS Server can be installed on any Windows 95/98/2000/NT PC to share your local drives and folders with other networked users, no matter which operating system they are running on their workstations. Only a NFS Client is required on that system for users to mount your disks as part of their system.

ProNFS Client

ProNFS Client can be installed on any Windows 95/98/2000/NT/XP PC to enable your workstation to benefit from networks NFS Server services. With the help of ProNFS Client you can mount disks and folders from network, no matter under which operating system they reside, and make them as part of your familiar local desktop environment.

New Features on this release include:

1. The following enhancements have been made :

1. FTP :
- saving of settings was improved.

2. Telnet :
- a review of runaway lines (as "old screens") was implemented.

3. NFS-Server :
- the ability to write files of more than 4GB size was implemented;
- the FL_CHRISLESLIE manual setting enables caching upon NFS writing;
- the FL_TZERAN manual setting enables changing the time zone difference.

4. NFS-Client for MS Windows NT4/2000/XP :
- the usage of SSH-2 Dynamic Forwarding was implemented. NFS-Client can access remote NFS-Servers through connections established with Telnet_SSH. Remote NFS-Servers must support TCP/IP access to portmapper, mountd and nfsd daemons;
- the NFS v.3 protocol support was implemented.

2. The following bugs have been fixed :

1. NFS-Server :
- extra socket listening was removed; - NFS-Server crashed while processing an incorrect inode number.

2. NFS-Client for MS Windows NT4/2000/XP :
- some bugs were fixed.

Undocumented Features

1. Comsetup :
- the "Auto-start XwpPeg Package Watcher" setting was implemented 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 especial 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).

3. 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;
- the "FL_MITXELENA=1" line can be inserted into the "[NFSSERVER]" section of the xwp.ini file to avoid directory permission problem for some NFS-Clients (e.g. of SCO UNIX 5.0.5).
This setting changes the default directory permission from 755 to 777.

4. NFS-Client for Windows NT4/2000/XP :
- the size of network packets can be changed instead of using the fixed 8K value;
- the full set of settings can be saved to a file and loaded from it later.
- the package is installed with the native Installation procedure (using the "Custom" installation mode) without necessity to deal with an additional separate executable;
- the links support was implemented (3 modes are available to do this).

5. Startup :
- to input any text into the command line before its executing, the "$(INPUTLIP)" macros can 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 "", then the resulting command line will be: xterm -display .
- the "Telnet_SSH/SSH2 (SSH-2 Client)" Start Method is similar to other methods except for the ending of a 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 :
- there may be 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";
- can fail when connecting to NFS-Server on another PC under Windows 9x if both PCs have Client/Server for Microsoft Networks installed.
