Someone made a nice post on how to fix this situation. I haven’t tried it, my mac is already rebuilding the backup, but it will be something I will try next time this error pops up.

• To prevent people from snooping on my passwords, https will be used as the protocol.
• It must work on the default https port (443) to prevent potential problems with firewalls.

Now on Ubuntu (the Linux of choice for this installation) any port below 1024 can only be used by a process running as root. Since I didn’t want to run subsonic itself as root, I decided to use Apache in front of my subsonic installation. Apache can bind the port as root and then drop its privileges to the “www-data” user, something I don’t think subsonic is able to do.

The result of my installation is the following setup:

• Apache running with https (ssl) on port 443. Apache will be reachable from the internet.
• Subsonic running on port 4040 as a “normal” http service. Since the connection from apache to subsonic runs on the same machine, there is no need for encryption here. With this configuration subsonic itself is not directly reachable from the internet, but only through apache.
• Apache will be configured as a so called reverse proxy to pass requests from apache to subsonic. This means your browser will talk to apache and Apache will talk to Subsonic.

Install Apache

The following command will install apache with support for https:

sudo apt-get install apache2 libapache-mod-ssl

Take note that for https, you will need the libapache-mod-ssl package, apache2 alone will not do https.

For ssl encryption we need to generate a so called “self signed certificate”.  There are a couple of ways to do this, I used the one described here. The steps are:

sudo mkdir /etc/apache2/ssl

sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/apache2/ssl/apache.key -out /etc/apache2/ssl/apache.crt

This last one will ask you a lot of questions. The most important one however is the “common name”, which shall not be empty. Enter your official domain name, or your IP. If you don’t have an official domain name, or your IP keeps changing, Please set up a dynamic DNS somewhere on the net. I got mine at afraid.org. For the rest of the article I will assume that your host will be called supersonic.mydomain.com, you will need to replace that with your personal URL.

Now we need to configure in such a way that it will proxy all the requests to subsonic. Since subsonic will be installed on port 4040 afterwards, apache will forward all requests to port 4040. Create the following file for your domain /etc/apache2/sites-available/supersonic-mydomain.com-ssl with the following content:

  
    ServerName supersonic.mydomain.com
    ServerAlias supersonic.mydomain.com
    ErrorLog ${APACHE_LOG_DIR}/error.log
    LogLevel warn
    CustomLog ${APACHE_LOG_DIR}/ssl_access.log combined
    SSLEngine on
    SSLCertificateFile /etc/apache2/ssl/apache.crt
    SSLCertificateKeyFile /etc/apache2/ssl/apache.key
    BrowserMatch "MSIE [2-6]" \
    nokeepalive ssl-unclean-shutdown \
    downgrade-1.0 force-response-1.0
    # MSIE 7 and newer should be able to use keepalive
    BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown
    ProxyRequests Off

      Order allow,deny
      Allow from all

    ProxyPass / http://127.0.0.1:4040/
    ProxyPassReverse / http://127.0.0.1:4040/

Now enable this configuration:

sudo a2ensite supersonic-mydomain.com-ssl
sudo service apache2 reload

Install subsonic

First you need to install some dependencies for the subsonic package:

sudo apt-get install lame flac faad vorbis-tools ffmpeg openjdk-6-jre

Then head over to subsonic.org and download the latest package for your distribution. After you have downloaded change to the directory holding the package and type:

sudo dpkg -i subsonic-4.7.deb

Please note that we will install subsonic to run without https support. The https protocol will be handled by apache, so the communication between apache and subsonic is unencrypted. Since both services run on the same machine this should not be an issue at all. Now modify the file /etc/default/subsonic to look like the one below:

#
# This is the configuration file for the Subsonic service
# (/etc/init.d/subsonic)
#
# To change the startup parameters of Subsonic, modify
# the SUBSONIC_ARGS variable below.
#
# Type "supersonic --help" on the command line to read an
# explanation of the different options.
#
# For example, to specify that Subsonic should use port 80 (for http)
# and 443 (for https), and use a Java memory heap size of 120 MB, use
# the following:
#
SUBSONIC_ARGS="--port=4040 --max-memory=512"

# The user which should run the Subrsonic process. Default "root".
# Note that non-root users are by default not allowed to use ports
# below 1024. Also make sure to grant the user write permissions in
# the music directories, otherwise changing album art and tags will fail.
SUBSONIC_USER=[the_name_of_your_unprivileged_user]

Now restart subsonic

sudo service subsonic restart

and check in your browser whether it all worked as intended:

https://supersonic.mydomain.com

As a result all communication with the site is now secure (we use 128 bit encryption).

For some reason I was unable to select the document type (dm_document). Neither could I select format. Funny, funny. Well since the customer said they had problems with the installation, I decided to reinstall. There was nothing in the repository anyway.

During the installation I normally change the datadictionary script to add support for the “de” locale. I noticed that the remarks in front of the “de” line had already been removed. But someone also included a remark in front of the “en” line. Now I didn’t really pay attention to it thinking that it might as well be correct.

How wrong I was. After the installation I still had the same problems creating a document. Turns out that enabling “en” in the repository and publishing the datadictionary fixed the issue.

Yeah right.

I don’t mind how well iTunes might serve others, for me it is just not working at all. I have around 7500 Ogg Vorbis files that just won’t really work. iTunes will play them, but forget about reading the metadata and artworks. You can workaround that issue, but to be honest, it is not worth the pain. The other main issue I have with the software is the inability to synchronise with the music collection I carry on a separate disk. This collection does not conform to the iTunes way of working, so syncing it to iTunes is a job I need to carry out manually. -For the iTunes lovers out there, there is a cool script that can handle that problem rather well. Get it at dougscript.com.-

So since I bought a Mac, I have been looking for an alternative. Preferably an application with integration to the likes of last.fm, wiki and whatever else is out there. Something like Amarok, which I used under Linux. I think I tried them all, but none of them really worked. The best match used to be songbird, which, although being almost a perfect fit, just was not able to handle any collection with more than 20.000 songs.

To be honest: I had already given up. I even converted als my precious FLAC files to Apple Lossless, so I could at least import them in iTunes correctly. And then there was spotify, which looked good enough, did the social thing and had almost everything I needed. So my music collection kinda became dusty and unused.

In comes Tomahawk with a jawbreaking set of features:

• It will automatically sync one or more folders on your PC. Music management with a file manager is just such a great invention, Apple should claim it for themselves in the next release of iTunes! -On a Mac you have to unhide your /Volumes folder with the following command: “sudo chflags nohidden /Volumes/”. Execute it in Terminal and Tomahawk can use your drives.-
• As they say on the website: it just plays. My Ogg Vorbis files are part of my collection again.
• It is social. Integration with Twitter, Google Talk and Jabber are included, so you can share the music you play with people you want. It also integrates with music recommendation services like last.fm.
• It integrates with metadata search engines like Musicbrainz.
• It has multiple content sources. You can use a shared iTunes library, a local collection, spotify and a subsonic server to get access to music. Hell you can even share your whole collection with friends, they can then stream your music to their PCs (stream, not copy). Check with your lawyer, before using this one though.
• It looks great. The first version I tested (0.4x) still looked like a ported application. The latest greatest (0.55) looks like a native Mac application.
• It runs on Windows, Mac and Linux. What else could you want?
• It is free and licensed under the GPL.

Next step: encryption, you never know if someone gets his hands on your laptop. Getting the encryption on the SSD (OS X installation disk) is easy, just do what you always do.

However the home disk is another story. Since OS X only asks for your password after logging in to the system and by that time you already need your home directory this is not something that can be done without any scripting.

Luckily those scripts are around. So after activating the encryption for your second drive fire up your browser and follow the instructions on https://github.com/jridgewell/unlock (do read the read me, it will save you a lot of time downloading and stuff). Works like a charm.

Taken from Dangerous Minds

I’ve found all of them to crash on me at least once a day. All, with one exception. The exception is called putty-nd. It is not fancy looking, but does what it should do. Now if it could only detach and reattach tabs…

Get it here.

usermod -u 1234 dmadmin
cd /opt/
chown -R dmadmin /opt/documentum
chown -R dmadmin [path_to_data_directory]

This all seems to work, however you will notice that as soon as you try to logon you will get “logon denied” messages ruining your day. The simple and obvious fix for this one is to execute the following as root:

sh /opt/documentum/dba/dm_root_task

Oh so obvious, but it took me some time and a little help to get there.
