Disk Usage

Command line

If you are geeky enough, the easiest and fastest way is to use the ‘df’ command in your terminal. Simply type

$ df -h

in the terminal and it will show the disk usage percentage of your hard disk.

$ du -a -m /app 2>/dev/null | egrep '.*[123456789]{3}\.[123456789]{2}.*/.*' | less

Change Hostname

The Command Terminal allows you to control your computer by typing a series of commands in the box.

  • into the command terminal
    • $ sudo pico /etc/hostname
  • Enter your administrative password
  • A window will open titled hostname (/etc) – pico. Replace your system's current name with the new one.
  • Select Save from the tool panel at the top of the window.
    • $ sudo pico /etc/hostname
  • change host name for 127.0.0.1
  • Select Save from the tool panel at the top of the window.
  • Close the Command Terminal.
  • Restart your system. -> here

Subversion

Subversion

Patch the system: 

pico /etc/apt/sources.list

deb http://ro.archive.ubuntu.com/ubuntu hoary universedeb-src http://ro.archive.ubuntu.com/ubuntu hoary universe
Installing

Install the required packages, running the following command: 

apt-get install libapache2-svn subversion subversion-tools

Creating your repository

Run as root: 

cd /home

mkdir /home/svn

chown www-data:tomcat6 /home/svn

su www-data -c "svnadmin create /home/svn/src"

Your repository will live in /home/svn/src.

Note that if you let your users run things as www-data (eg. they can install CGI applications) they will be able to write to your repository!

Configure Apache

Become root again and add the following lines to our apache configuration (ssl), inside of the VirtualHost declaration.


$pico /etc/apache2/mods-enabled/dav_svn.conf 

<Location /svn/src>

DAV svn

SVNPath /home/svn/src

AuthType Basic

AuthName "QBW Subversion Repository"

AuthUserFile /home/svn/.dav_svn.passwd

Require valid-user

</Location>

If you don't want to use passwords for read-only access, use this instead of the Require valid-user line: 

  <LimitExcept GET PROPFIND OPTIONS REPORT>

    Require valid-user

  </LimitExcept>

Once you've applied these changes,

  • Restart apache2 /etc/init.d/apache2 restart

    • Create some users

    Add an user with the following command: 

    su www-data -c "htpasswd -c -m /home/svn/.dav_svn.passwd user"

    The -c is only required the first time you run this command, in order to create the passwords' file. Subsequent runs won't require it: 

    su www-data -c "htpasswd -m /home/svn/.dav_svn.passwd user"

    Note that the passwd file does not need to be created as www-data. It can be created as root, for example. However, it must be visible by www-data.

    In the meantime htpasswd had changed – htpasswd will do it (apache2 – Version: 2.2.4-1 on Debian apache2-utils_2.2.4-1_i386.deb)

    Testing the repository

    Using your browser. Load https://hostname/svn/src/ in your browser. Replace hostname with your host name or ip. You will get something like: 

    Revision 0: /Powered by Subversion version 1.1.3 (r12730).

    Import your initial data: 

    svn --username user import src https://localhost/svn/src -m "initial import"Authentication realm: <https://localhost:443> My Subversion RepositoryPassword for 'user':Adding         src/checkersAdding         src/checkers/trunkAdding         src/checkers/trunk/gendelta.plAdding         src/checkers/siteAdding         src/checkers/branchesAdding         src/checkers/tags

    Committed revision 1.

    Now load your URL in your browser again and make sure you can browse what you imported: 

    - checkers/Powered by Subversion version 1.1.3 (r12730).

    backup/restore repository

    sudo su

    backup repo 

    $ svnadmin dump /media/shares/svn > /media/backup/svn.dump

    WIN CMD: svnadmin dump d:\QBW_Subversion\repository > d:\QBW_Subversion\svn.dump

    create a new repo 

    mkdir src2

    chown www-data:tomcat6 src2

    svnadmin create /home/svn/src2

    restore to a new repo 

    svnadmin load --force-uuid /home/svn/src2 < /var/svn.dump

    mv /home/svn/src /home/svn/src_old

    mv /home/svn/src2 /home/svn/src

    Restoring from Backups (svn.qbytesworld.info) webfactions

    Backups can be restored with the svnadmin‘s load command. To restore a backup:

    1. Open an SSH session to your account.

    2. Switch to the directory of a new Subversion application. Entercd ~/webapps/svn, where svn is the name of the Subversion application as it appears in the control panel, and press Enter.

    3. Enter svnadmin load . < dump_file where dump_file is the path to the backup, and press Enter.

    Note

    To prevent your restoration from being stopped for excessive processor utilization (particularly for repositories with many commits or a large total file size), prefix the svnadmin command with the nice command for deference to other processes:

    nice -n 19 svnadmin load . < dump_file

    Setup OpenSSH Server on Ubuntu Linux

    This is only needed if you did not install as part of setup.

    Run this command from a terminal window:

    $ sudo apt-get install ssh

    To test that it’s working, you can try to ssh into your own machine:

    > ssh localhost

    The authenticity of host ‘localhost (127.0.0.1)’ can’t be established.
    RSA key fingerprint is 98:8a:b8:b2:9e:8a:84:e0:d4:08:27:fb:74:f0:de:d4.
    Are you sure you want to continue connecting (yes/no)?

    Looks like it’s working! Naturally our ssh client doesn’t have the key for the server, since we just installed it. You can type yes to continue or just hit Ctrl-C to stop.
