Exchange Setup does not work because of Domain Name System settings on the domain controller

To resolve this issue, make sure that the DNS settings on the schema master domain controller and the member server are pointed to valid internal DNS servers.

1. Right-click My Network Places, and then click Properties in the shortcut menu to open the Network and Dial-up Connections dialog box.
2. Right-click Local Area Connection, and then click Properties in the shortcut menu.

howto install SVN (Subversion) server on Fedora 16/15/14/13, CentOS 6/5.7, Red Hat (RHEL) 6.1/6/5.7.

What is SVN (Subversion)?

Subversion is a free/open-source version control system. Subversion manages files and directories, and the changes made to them, over time. This allows you to recover older versions of your data, or examine the history of how your data changed. In this regard, many people think of a version control system as a sort of “time machine”.

Install SVN (Subversion) Server on Fedora 16/15/14/13, CentOS 6/5.7, Red Hat (RHEL) 6.1/6/5.7

1. Change root user

su -
## OR ##
sudo -i

2. Install needed packages (mod_dav_svn and subversion)

yum install mod_dav_svn subversion

Note: If you don’t have Apache installed already, this command installs it also. Read more about installing Apache and PHP >>

3. Modify Subversion config file /etc/httpd/conf.d/subversion.conf

Add following config to /etc/httpd/conf.d/subversion.conf file:

LoadModule dav_svn_module     modules/mod_dav_svn.so
LoadModule authz_svn_module   modules/mod_authz_svn.so
 
<Location /svn>
   DAV svn
   SVNParentPath /var/www/svn
   AuthType Basic
   AuthName "Subversion repositories"
   AuthUserFile /etc/svn-auth-users
   Require valid-user
Location>

## Create testuser ##
htpasswd -cm /etc/svn-auth-users testuser

5. Create and configure SVN repository

mkdir /var/www/svn
cd /var/www/svn
 
svnadmin create testrepo
chown -R apache.apache testrepo
 
chcon -R -t httpd_sys_content_t /var/www/svn/testrepo
 
## Following enables commits over http ##
chcon -R -t httpd_sys_rw_content_t /var/www/svn/testrepo

Restart Apache:

/etc/init.d/httpd restart
## OR ##
service httpd restart

Goto http://localhost/svn/testrepo address and you should see something like following, write username and password:

SVN testrepo revision 0:

6. Configure repository

To disable anonymous access and enable access control add following rows to testrepo/conf/svnserve.conffile:

## Disable anonymous access ##
anon-access = none
 
## Enable access control ##
authz-db = authz

7. Create trunk, branches and tags structure under testrepo

Create “template” directories with following command:

mkdir -p /tmp/svn-structure-template/{trunk,branches,tags}

Then import template to project repository using “svn import” command:

svn import -m 'Initial import' /tmp/svn-structure-template/ http://localhost/svn/testrepo/
Adding         /tmp/svn-structure-template/trunk
Adding         /tmp/svn-structure-template/branches
Adding         /tmp/svn-structure-template/tags
 
Committed revision 1.
