Windows 10 will try to negotiate SMB3_11, which Samba4 doesn't yet support
except in the current 4.3 release candidate. I suspect for now disabling
SMB2/3 on the Windows 10 client is your best, if not ideal, option.
 
 
To disable SMBv2 and SMBv3 on the SMB client, run the following commands:
<pre>
sc.exe config lanmanworkstation depend= bowser/mrxsmb10/nsi
sc.exe config mrxsmb20 start= disabled
</pre>
To enable SMBv2 and SMBv3 on the SMB client, run the following commands:

=====Howto manage container=====


Steps I've taken to make my laptop a Subversion server. Credit must go to AlephZarro for his directions here. I now have a working SVN server (which has currently only been tested locally).
See [[Unix Container | Container Howto]] for the usage

Apache Svn Server

1: Install Apache HTTP server and required modules: 

sudo apt-get install libapache2-svn apache2

2: Enable SSL 

sudo a2enmod ssl
sudo vi /etc/apache2/ports.conf

Add or check that the following is in the file: 

<IfModule mod_ssl.c>
    Listen 443
</IfModule>

3: Generate an SSL certificate: 

sudo apt-get install ssl-cert
sudo mkdir /etc/apache2/ssl
sudo /usr/sbin/make-ssl-cert /usr/share/ssl-cert/ssleay.cnf /etc/apache2/ssl/apache.pem

4: Create virtual host 

sudo cp /etc/apache2/sites-available/default /etc/apache2/sites-available/svnserver
sudo kate /etc/apache2/sites-available/svnserver

Change (in ports.conf): 

"NameVirtualHost *" to "NameVirtualHost *:443"

and (in svnserver) 

<VirtualHost *> to <VirtualHost *:443>

Add, under ServerAdmin (also in file svnserver): 

SSLEngine on
SSLCertificateFile /etc/apache2/ssl/apache.pem
SSLProtocol all
SSLCipherSuite HIGH:MEDIUM

5: Enable the site: 

sudo a2ensite svnserver
sudo /etc/init.d/apache2 restart

To overcome warnings: 

sudo vi /etc/apache2/apache2.conf

Add: "ServerName $your_server_name"

Add, under ServerAdmin (also in file svnserver): 

SSLEngine on
SSLCertificateFile /etc/apache2/ssl/apache.pem
SSLProtocol all
SSLCipherSuite HIGH:MEDIUM

6: Adding repository(ies): The following setup assumes we want to host multiple repositories. Run this for creating the first repository:
