ProNFS Version 2.5 - NFS Client and Server by Labtam.

Date: May 9 2005

Labtam is pleased to present a new software update for ProNFS now Version 2.5. It is the first major release for the 2005 year.

An 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/NT/2000 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. FTP:
- FTP can copy files with illegal symbols using a map table

2. Startup:
- implemented the Telnet startup mode
- implemented the "-lxdn [<DisplayNumber>]" option to set up the "$(DISPLAYNUMBER)" macros (the "-lxdn" option means lookup running XServer). In this case, the XServer must already have been started

3. NFS-Server:
- refuses to close and shut down system if mounts are active
- supports the fixed or static port assignment
- made some changes concerning export names in the graphic interface
- some illegal symbols (such as '*',':','$','|') in file names can be used. (i.e. CATIA often tries to create file names with mentioned symbols)

4. Telnet:
- Telnet can be started as a non-interactive session via Startup facility
- 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 XServer)
- Telnet understands the local XServer's "DynamicDisplayNumber" mode and correctly looks for the running XServer

5. NFS-Client for MS Windows NT4/2000/XP:
- implemented the dynamic allocation of inodes to accept large exports
- implemented the WebNFS protocol
- increased the maximal numbers for accepted NFS-Servers and exported directories
- upgraded the NFSProbe utility

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. NFS-Server :
- fixed the bug when the number of inodes exceeds maximal value
- corrected the 'inremnode failed' message

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

4. NFS-Client for MS Windows NT4/2000/XP :
- the "ls *" command line of MS SFU Korn Shell got caught in an endless loop of NFS requests to the NFS-Server
- processing of the Server List is more correct now
- a name of a mapped drive is shown correctly now

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 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).

Known problems

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

2. 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.

3. 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.

Single User licenses are at $40.00 USD. Please visit the Software Pricing page for pricing on Multiple Licenses.

The programs associated in this package may send and/or receive broadcast IP requests. Since such packets cannot cross the nearest firewall/gateway/router, please be sure that these IP requests are invisible from outside your network. We assume that such behavior cannot be considered as "Hacking" or "Trojan horse's action".
