Sebastian Nagel commented on NUTCH-2856:
----------------------------------------
NUTCH-427 was rejected because of license issue - LGPL isn't compatible with
the Apache license and would put restrictions on the Nutch source code, see
[1|https://www.apache.org/legal/resolved.html]. jcifs-codelibs and jcifs-ng are
also licensed under LGPL-2.1, so we cannot include them also in binary form.
This would leave SMBJ ([jar on Maven
repository|https://mvnrepository.com/artifact/com.hierynomus/smbj]) as the only
option to try to build a up-to-date protocol-smb. [~hiranchaudhuri], would you
be able to work on this?

> Key: NUTCH-2856
> URL: https://issues.apache.org/jira/browse/NUTCH-2856
> Project: Nutch
> Issue Type: Bug
> Components: external, plugin, protocol
> Reporter: Hiran Chaudhuri
> Priority: Major
> Fix For: 1.19

> The plugin protocol-smb advertized on
> [https://cwiki.apache.org/confluence/display/NUTCH/PluginCentral] actually
> refers to the JCIFS library. According to this library's homepage
> [https://www.jcifs.org/]:
> _If you're looking for the latest and greatest open source Java SMB library,
> this is not it. JCIFS has been in maintenance-mode-only for several years and
> although what it does support works fine (SMB1, NTLMv2, midlc, MSRPC and
> various utility classes), jCIFS does not support the newer SMB2/3 variants of
> the SMB protocol which is slowly becoming required (Windows 10 requires
> SMB2/3). JCIFS only supports SMB1 but Microsoft has deprecated SMB1 in their
> products. *So if SMB1 is disabled on your network, JCIFS' file related
> operations will NOT work.*_
> Looking at
> [https://en.wikipedia.org/wiki/Server_Message_Block#SMB_/_CIFS_/_SMB1:|https://en.wikipedia.org/wiki/Server_Message_Block#SMB_/_CIFS_/_SMB1]
> _Microsoft added SMB1 to the Windows Server 2012 R2 deprecation list in June
> 2013. Windows Server 2016 and some versions of Windows 10 Fall Creators
> Update do not have SMB1 installed by default._
> As a conclusion, the chances that SMB1 protocol is installed and/or
> configured are getting vastly smaller. Therefore some migration towards
> SMB2/3 is required. Luckily the JCIFS homepage lists alternatives:
> * [jcifs-codelibs|https://github.com/codelibs/jcifs]
> * [jcifs-ng|https://github.com/AgNO3/jcifs-ng]
> * [smbj|https://github.com/hierynomus/smbj]
