Tang Huan Song commented on CONNECTORS-1498:
--------------------------------------------
In addition to the changes required for the upgrade to utilize jcifs-ng over
the current jcifs library, I'd like to also suggest allowing the user to tweak
basic jcifs/jcifs-ng parameters in order to suit the target fileserver.
I'm unsure whether it's better to make it a connector-wide setting (and have it
adjustable via ManifoldCF's properties.xml) or have it modifiable
per-connection, but at the moment I have the former in mind.
Perhaps implementation could go like the following, placed within a static
block in the SharedDriveConnector class.
{code:java}
System.setProperty("jcifs.smb.client.soTimeout",
ManifoldCF.getStringProperty("jcifs.smb.client.soTimeout", "..."));
{code}
with the following settings and their suggested defaults:
* jcifs.smb.client.soTimeout: 150000
* jcifs.smb.client.responseTimeout: 120000
* jcifs.resolveOrder: DNS
* jcifs.smb.client.listCount: 20
* jcifs.smb.client.dfs.strictView: true
* jcifs.traceResources: true
* jcifs.smb.client.minVersion: SMB1
* jcifs.smb.client.maxVersion: SMB210
* jcifs.traceResources: true
* jcifs.smb.client.ipcSigningEnforced: true
> Support SMBv2/v3 protocol for Windows Shares connector

> Key: CONNECTORS-1498
> URL: https://issues.apache.org/jira/browse/CONNECTORS-1498
> Project: ManifoldCF
> Issue Type: Improvement
> Components: JCIFS connector
> Environment: OS: CentOS 7.2
> ManifoldCF: 2.8.1
> Reporter: Hiroaki Takasu
> Assignee: Karl Wright
> Priority: Major
> Fix For: ManifoldCF 2.10
>
>
> Windows Shares connector (JCIFS connector) uses
> [JCIFS|https://jcifs.samba.org/] library which supports only samba protocol
> v1.
> But many file servers were disabled SMBv1 by vulnerability
> [MS17-010|https://docs.microsoft.com/en-us/security-updates/SecurityBulletins/2017/ms17-010],
> so we can not use Windows Shares connector.
> I hope that ManifoldCF support SMBv2/v3 with other CIFS library (e.g.
> [smbj|https://github.com/hierynomus/smbj])
