To run JFileServer from the command line you first need to download the latest JFileServer Kit zip file from here.

Unpack the JFileServer Kit zip file into a new folder. You should now have a folder with the following files and folders :-

/jfileserver
 |
 +- /testShare
     |
     +- sharedFile.txt
 +- /lib
     |
     +- bcprov-jdk5on-1.48.jar
     +- hazelcast-3.10.1.jar
     +- jfileserver-1.1.1.jar
     +- jna-5.1.0.jar
     +- jna-platform-5.1.0.jar
 +- fileSrvConfig.xml
 +- port445.reg
 +- runsrv.bat
 +- runsrv.sh

Using JFileServer On Windows

On Windows the default JFileServer configuration runs the SMB server using the native SMB port 445. In order for this not to clash with Windows using the same port a registry edit is needed. The JFileServer kit includes the port445.reg file to switch off the Windows OS use of port 445. To apply the registry edit double click the port445.reg file, then restart Windows.

Switching off port 445 on Windows may have other side effects on the Windows host, an alternative way to run JFileServer is by using the Docker images, details of how to use the Docker images are here.

Once the registry edit has been applied, use a terminal command line or shell and set the current working directory as the folder where you unpacked the JFileServer kit zip file.

To start JFileServer on Windows use the runsrv.bat batch file :-

runsrv

The default JFileServer configuration will output debug logging to the console, on startup of the server you should see the following :-

JFileServer starting, enter 'x' to shutdown server, 'r' to restart server ...
Starting server NetBIOS ...
Starting server SMB ...

To stop the running JFileServer enter x into the console and hit <Return>, the file server should shutdown within a few seconds, but may take up to a minute or so :-

Using JFileServer on linux, macOS, Unix

On linux, macOS and Unix systems the default JFileServer configuration runs the SMB server using native SMB but via the non-privileged port 1445, so that JFileServer can be run using a normal user account. To run JFileServer on port 445 would require running JFileServer using the root user.

In order for SMB clients to be able to connect to the JFileServer SMB server when it is running on a non-privileged port we need to use the firewall to forward network packets from the default port of 445, that the client will connect to, to port 1445 that the JFileServer SMB server is listening on.

Setting Up Port Forwarding On Linux

Setting Up Port Forwarding On macOS

On more recent versions of macOS (10.10 onwards) the packet filter device is used to control forwarding of network packets. The packet filter is configured using the /etc/pf.conf file and associated files in the /etc/pf.anchors folder.

To enable forwarding of network traffic from port 445 to port 1445. :-

  • Edit the /etc/pf.conf file, add the lines in bold. You will need to run the editor using the sudo command.
#
# com.apple anchor point
#
scrub-anchor "com.apple/*"
nat-anchor "com.apple/*"
rdr-anchor "com.apple/*"
rdr-anchor "org.filesys"
dummynet-anchor "com.apple/*"
anchor "com.apple/*"

load anchor "com.apple" from "/etc/pf.anchors/com.apple"
load anchor "org.filesys" from "/etc/pf.anchors/org.filesys"
  • Create the org.filesys anchor file in the /etc/pf.anchors folder, add the following line :-
rdr pass on en0 inet proto tcp from any to any port 445 -> 127.0.0.1 port 1445
  • Enable the port 445 forwarding rules using :-
sudo pfctl -e -f /etc/pf.conf -v



Using a command line terminal or shell set your current working directory as the JFileServer directory.

There is a default JFileServer configuration file that will share the testShare folder, which contains a single text file. For details on configuring JFileServer see here.

To start JFileServer on linux, macOS or Unix system use the runsrv.sh script file :-

./runsrv.sh

On Windows use the runsrv.bat file to start JFileServer :-

runsrv

The default JFileServer configuration will output debug logging to the console, on startup of the server you should see the following :-

JFileServer starting, enter 'x' to shutdown server, 'r' to restart server ...
Starting server NetBIOS ...
Starting server SMB ...
