Hi OnTheRoad41, this error message indicates that the site is trying to use an obsolete encryption cipher which is vulnerable to the "Logjam" attack that was in the news earlier this year.
What does that mean?
Even though you trust the server, a "Logjam" attack compromises the security of your individual connection to the server, lowering the protection normally provided by SSL to a level that is easily cracked and read by others on the network. That is why Firefox protects you from making this connection.
What can you do now?
The very best solution for the protection of all users of that server is for United to change some settings on the server. If the information you can view on the server is sensitive, then this fix is overdue, so we encourage you to report the problem ASAP.
If you cannot wait, you can try disabling these old ciphers in your Firefox, which hopefully will force the server to try some more secure ciphers when connecting with you. Here's how:
(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.
(2) In the search box above the list, type or paste dhe and pause while the list is filtered
(3) Double-click the security.ssl3.dhe_rsa_aes_128_sha preference to switch it from true to false (disable Firefox from using this cipher)
(4) Double-click the security.ssl3.dhe_rsa_aes_256_sha preference to switch it from true to false (disable Firefox from using this cipher)
Then try the site again; you might have to reload the page using Ctrl+Shift+r to bypass cached information.
Success?

Dark blue on Linux terminal difficult to read

Change Blue into Cyan ... it is just a lot more readable.

How?
Very easy once you know it:

Open a shell and stay in your home directory.
Do the following:

$> dircolors | sed -e "s/34/36/" > setColors.bash

This will create the file setColors.bash containing the current color settings for the terminal with the value of 34 changed into 36.

To try the setting, do the following:
$> .  ./setColors.bash

Your current terminal session will now show directories in cyan instead of blue. Use ls -l to see the difference. Notice also the dot followed by a space in front of ./setColors.bash.

To make the change for all your future sessions, you need to modify the profile script which is run when you create the terminal session. In case you're using bash, look for the .profile_bash file.

You can then either copy the content of the setColors.bash file into the profile file or call the execution of it. Make sure to execute the script in the current shell  and not in a subshell by using the mentionned dot space notation.

Reference and solution found here

I needed to remove the screenshots ... thanks blogspot ... just doesn't work.

Example of how it looks before the change:

The output of dircolors: (notice the 34's)


Create the setColors.bash script:


The content of the setColors.bash file: (notice the changed values for 34 into 36)


The line appended in the .bash_profile file in the hone directory of the user:



Example of how it looks after the change:

Very nice showcase of alternative solution for journalling tables ... including a demonstration of what should rule out this solution in some cases !!!

Vasco card readers on Mac OS X 10.9

Having to use 'a card reader' bought myself a good looking Vasco 905 device.
You may run into this problem because of the fact that for example KBC is distributing the same device but not with the vasco logo but with ... KBC.

After the upgrade to Mac OS X v 10.9 the thing did not work anymore.

Looking around on the net I found the following post on the Vasco website: https://retail.vasco.com/du/install/faq/20100114_990081.aspx

In this post a clear distinction is made between version 1.1 and version 2.0 of the card reader.
How to determine the version is also indicated.

Actions to take:
Version 1.1 -> ask for a new one. the procedure to do so is clearly indicated
version 2.0 -> use terminal session -> pcsctest
if this doesn't show all details:

Ubuntu - Setup Eclipse wiht Java EE, Maven for Spring development

Context

Starting with a new toolset requires a clean drawing board and - as I believe this is currently the best solution -be able to go back in time where things still worked ;-)
The aim is to create a VirtualBox VM with Ubuntu as OS.
The toolset to be installed for the development is Java (and EE), Eclipse, Maven, Spring) ... for now at least. I suppose a number will need to be added to the stack but I'll add them along the way.

Thanks to a number of sources I used to fall back in the need to sharpen (better but not to say is build) my knowledge of the Ubuntu Desktop environment. It's yet an other kind of Linux than the one I'm used to. (Redhat, Fedora, Oracle Linux ... )

Ubuntu is based on Debian and ... if I recall well Debian is also the basis for Mac OS X ...my platform in favour.

RadiAnt - Open folder with context menu

RadiAnt is Such a wonderfull Dicom viewer. (download)
The only thing missing by default is to open a folder immediately with Radiant.
In order to do this you need to add a registry key which will define the "Radiant" action for all directories.

The steps to do this:

• Open Regedt
• Go in the registry to the following location:
• HKEY_CLASSES_ROOT > Directory > shell
• Verify that you can see at that level two entries: cmd and find
• Create a new item called “Radiant”
• Go to the newly created item “Radiant”
• Create a new item called “command”
• In de standard REG_SZ string enter the path to Radiant between double quotes followed by %1

For example:
"c:\Program Files\RadiAntViewer64bit\RadiAntViewer.exe" %1

VirtualBox on Mac os x - Can not find com service

Context

Mac Mini Server edition, 16 GB ram, ssd 250GB + hdd 750GB
Mac OS X server
Oracle VirtualBox
Changed (decent word for testing if something would fail) with the Mac OS X server settings, in particular the hostname.

Symptoms

Trying to start the admin screen of VirtualBox fails and gives an error telling that the tool could not connect to the COM service or the VirtualBox com services.
In the details of the error you will find something link NS_ERROR_FAILURE (0x80004005)

Explain

Do not know what is going wrong, but something is smuthering up the file and directory permissions when the hostname is changed and/or Mac OS X server services are recreated and/or restarted

Solution

Go to disk utility (Utilities > Disk Utility)

Select the main disk of the computer on the left pane

Select the first aid tab (the default one)

Click on the button to "Repair the disk permissions"

In the log file you'll see things that seem not to interfear with VBox ... at first ... but looking deeper in the stack ... 

Hope this solves your problem too ...

Win Server Z008 r2 - Run applications as different users

Problem:
An administrator installs an application on the server.
Other non-administrator users are unable to run the application.

References:
http://technet.microsoft.com/en-us/library/ee791868(v=ws.10).aspx

Problem:
Application locker is to restrictive

Solution:
Adapt the permissions of the program and probably the folder.

a. Program Permissions
windows-run : secpol.msc
Select Application Control Policies > AppLocker
Create a new rule in the Executable Rules for the program.

b. set sharing of files/folders permissions.
Some programs require access to the file folders or to specific files.
Click on the file/folder and in the context menu select "Share".
Add the correct users or groups and set the permissions to read/write according to the requirements.

Win Server 2008 r2 - iPad rdp connection to server

Problem:
When connecting via an RDP client app on iPad, you get the message "The requested session access is denied".
This connection is possible when connecting as an Administrator user but not as a 'normal' user.

Reason:
Most clients connect to the console by using the /console option, which is only possible for administrators.

Solution:
Found an iPad app that contains the option to define a connection to the server with the option not to specify /console : 2X (website www.2x.com)
Create a profile to connect via a specific user and in the profile of the server the last option is "Connect to console" which has to be set to Off.
