Unable to setup alerts on a Drac / Integrated Dell Remote Access Controller 6 Enterprise

If you have a DRAC / Integrated Dell Remote Access Controller 6 - Enterprise and are unable to set up alerts via Google Chrome, I have noticed a little bug where the menu simply states "ok" instead of going to the correct page.

The easiest solution is simply to use Internet Explorer, however, I recommend you attempt to upgrade the DRAC to the latest version available, this is a painless process and does not require the server to be reset.

Next, try pressing the Control + F5 to refresh your cache and you should hopefully now be able to get in to the menu.

I have been seeing mixed reports on this - it appears to work for some people and others seem to still have the bug... Hopefully you will be one of the ones it works fine for.

Android error sending email: Unable to sign or encrypt message certificate not installed

Someone in the office came to me with a problem today, saying that every time they tried to send an email, the following message is displayed:

unable to sign or encrypt message certificate not installed

It turns out that, for some reason, the option to sign outgoing messages had been turned on by accident - without any client certificate installed for this feature to actually work.

To fix it - there are two options:

1) Install a client certificate if you actually want to sign outgoing emails.

2) Turn signing off.

Hardly anyone signs emails and I am guessing that most people who want to use it will already know how to!

As for turning signing off, it is pretty straight forward.

1. Go to Email settings (Easiest is in the email client, click the menu button and go to settings).

2. Go down to Security Options

3. Untick sign.


Hope this helps!

How to generate a HTTP 400 error from a client

First blog post in a while! I have hardly had any free time... Will blog about it soon!

Anyway, I have needed to generate a 400 error on a server in order to test something - I tried a few things without success and then I discovered that the easiest way to generate a 400 error from a client is simply to add a percentage symbol (%) to the request.

For example, http://mysite.com/% should generate a 400.

Before I found out I could use the percentage symbol, I was looking for a method involving telnet/direct connections. Oliver Salzburg on Super User came up with the following -

... I don't know if this will help anyone, but, if I had found a post like this earlier today, it would have saved me quite a bit of time, so, I hope someone will find it useful!
