Problem

Set up Ubuntu workstation to provide SVN using Apache and WebDAV.

Analysis

There are basically 2 ways to do it:

1. ssh+svn
2. https (using webdav)

Solution

We take the second one.

# apt-get install libapache2-svn
# cd /etc/apache2/sites-enabled
# vi 000-default

The content of 000-default:

    <Location /svn/repos>
      AuthType Basic
      AuthName "Subversion Repository"
      AuthUserFile /etc/apache2/passwd
      Require valid-user

      DAV svn
      SVNPath /var/svn/repos
    </Location>

Reload web server:

/etc/init.d/apache2 force-reload

Create your password file:

htpasswd -c /etc/apache2/passwd user

Problem

On Ubuntu remote display in X doesn not work.

Analysis

We need to remove “-nolisten tcp” from X command line.

Solution

1. This is sometimes in “/etc/X11/xinit/xserverrc”, but in Ubuntu you just need to configure GDM:Create or edit file /etc/gdm/custom.conf with the following content:

   [security]
   DisallowTCP=false

2. Restart X or reboot.
3. On the remote machine

   $ export DISPLAY=yourcomputer:0.0

4. On local machine

   $ xhost + remotemachine
