A. Introduction
The protocol-smb plugins allows you to crawl Microsoft Windows shares. It implements
the CIFS/SMB protocol which is commonly used on Microsoft OS. The plugin replicate the
behaviour of the protocol-file over CIFS/SMB protocol. This plugin uses the JCifs library and also
support all the properties from the JCifs library.
You can find more information on the following site: http://jcifs.samba.org/
The smb protocol syntax for crawling is as follow: smb://xxxxx (i.e. smb://server/share).
B. Installation
1) Binaries only: The protocol-smb files can be found in the ../plugins directory.
Copy the "protocol-smb" to NUTCHHOME/build/plugins directory.
Put the "smb.properties" file in the NUTCHHOME/conf directory.
Configure the properties in "smb.properties" file
Enable the plugin by updating "nutch-site.xml" file found in NUTCHHOME/conf directory
e.g. <property>
<name>plugin.includes</name>
<value>protocol-smb| other plugins...</value>
<description>
</description>
</property>
2) Source code: The protocol-smb sources can be found in the ../src directory.
Always refer to the Nutch wiki for detailed instructions on building Nutch. In short:
Copy the 'protocol-smb' folder to NUTCHHOME/src/plugin
Update the build.xml in NUTCHHOME/src/plugin to include plugin
Update the NUTCHHOME/default.properties file to include plugin
run ant to build
Copy the 'smb.properties' file to NUTCHHOME/conf, and configure the properties
Enable the plugin by updating the nutch-site.xml file
C: Known Issues
1) URLMalformedException: unkown protocol: smb
The SMB URL protocol handler is not being successfully installed.
In short, the jCIFS jar must be loaded by the System class loader.
Workaround: a) a short term solutions will be to installed the JCIFS jar
library found in protocol-smb folder in
JDKHOME/jre/lib/ext and (or) JREHOME/lib/ext
b) After completing step a), if the exeception is still thrown
set the System properties by passing the following arguments
to the JVM:
-Djava.protocol.handler.pkgs=jcifs
c) You can set the property also in your Code for example if
you start Crawling with org.apache.nutch.crawl.Crawl
Add the following two lines. This will be the Same like in b)
public static void main(String args[]) throws Exception {
System.setProperty("java.protocol.handler.pkgs", "jcifs");
new java.util.PropertyPermission("java.protocol.handler.pkgs","read, write")
//and so on
Also you can visit the FAQ page: http://jcifs.samba.org/src/docs/faq.html
2) FATAL smb.SMB - Could not read content of protocol: smb://xxxxxx
This problem usually occurs if the following properties are not set correctly in
the "smb.properties" file:
- username
- password
- domain
Also refer to the following resources for more information on the list of
available properties and how to set them:
http://jcifs.samba.org/src/docs/api/overview-summary.html#scp
Also you can visit the FAQ page: http://jcifs.samba.org/src/docs/faq.html
N.B. All properties should set in the "smb.properties" file. You can set
all supported JCIFS properties in the "smb.properties" file.
3) Only tested on Windows XP and Windows Server 2003. Please report any tests
conclusion on other OS.
