Allegro NFS Server for Microsoft Windows in Common Lisp


Ahmon Dancy, Franz Inc. Elliott Johnson, Franz Inc. Kevin Layer, Franz Inc.

Author comments

Allegro® NFS Server for Windows® was inspired by our dissatisfaction with current free and commercial NFS Servers available on the market and the incredible technical difficulties we faced in configuring them on Windows.


Microsoft Windows XP and newer (including Windows 8).


Cygwin (GNU make). Allegro Common Lisp 9.0 (32-bit, non-SMP).


To build:

make all

To install:

make install

The install step expects that cygwin has C:\ mounted as /c. It is also possible to build an installer via:

make installer

This will produce an nsi file that can be used to install.


See the nfs documentation for more information on how to configure nfs.


Once your exports are configured it's possible to mount them. Please consult your platforms documentation on how to mount remote nfs partitions.


Interactive debugging of server:

:ld loadem

Then, for debugging:

(debugmain) ;;

Or, without debugging:

(setf configfile "nfs.cfg") (read-nfs-cfg configfile) (startem)

:cd d:/src/nfs50/ (load "loadem") (setf configfile "nfs.cfg") (read-nfs-cfg configfile) (startem)


(prof:stop-profiler) (defun doit (file) (with-open-file (standard-output file :direction :output :if-exists :supersede) (prof:show-flat-profile) (prof:show-call-graph) #+ignore (prof:disassemble-profile 'excl::g-read-vector-2))) (doit "y:/nfs.82brc5") (doit "y:/nfs.81")

(prof:show-flat-profile) (prof:show-call-graph)
