OCSP part 6 – Test OCSP service

To test if OCSP is working, you need to have a certificate with OCSP information included. This is only available for certificates emitted AFTER the service was installed, configured and activated on the CA. Therefore, you`ll need to first create a new certificate for your tests. Depending on your CA configuration, you can use OpenSSL to create a request or will have to use the Windows integrated tools. I will show here how to use a CSR created by OpenSSL and a Windows Enterprise CA.

Create CSR with OpenSSL

openssl req –new –newkey rsa:2046 –nodes –keyout dummy.key –out dummy.csr

This creates a key file and the CSR in Base64.

Submit CSR to CA

Certificate snap-in

MSFT Enterprise CA needs the CSR created for a specific template, something that OpenSSL is not offering. If you submit such a request to the CA via MMC, you get an error message.

More information

CA Web Interface

Open the web enrollment server in your browser. Click on Request a certificate.

Go to the advanced options.

Paste the Base64 encoded CSR in the input field. Select as certificate User.

Submit the request and download the generated certificate.

Take a closer look at the certificate. In the AIA section, OCSP must be shown.

Test OCSP service

In the above step, a new user certificate was created, containing OCSP information. To test if OCSP is working, Microsoft is offering the certutil tool.

certutiil –URL dummy.cer

In the Retrieve box, you can select how to certificate information should be retrieved.

Select OCSP.

Check the status

Result: Failed

Result: Unsuccessful

Result: Verified

Initial setup of Personas 3 – 7 – Test Personas 3

Final step to execute when configuring Personas for the first time is to check if it actually works. The health check tool shows that the configuration is OK; no more steps needed now to take Personas 3 for a test drive. It is time to access Personas 3! Best way to do so is to call Personas 3 from a browser. If you do not know already the URL of the app, you can call the ICF node directly from SICF.

  • Tx: SICF
  • Virtual Host: DEFAULT_HOST
  • Service Name: PERSONAS

Test service

This opens your default browser and automatically opens the personas app: /sap/bc/personas.

Wait, what? That`s Personas 3? Easy, look at the top middle of your screen.

Click it. Yeah, that`s Personas 3.

Test available internet bandwidth under Linux

Let the world know ...Tweet about this on TwitterShare on Google+Share on FacebookEmail this to someoneShare on LinkedIn

It’s 2015 and somehow I think that is a reason to simply have enough bandwidth for upload and download to help me with my digital life style. Cloud is in, and accessing files from everywhere is tempting. As cloud only means to be able to access data from any internet connection, I can host the data also at home. Only thing needed for this is a upload bandwidth that is not too slow. But what is the upload and download rate available in my data plan? I am a NET customer and after a few upgrades over the years I am not at 15 Mbps. This should give me 2 Mbps upload. How to measure this under Linux?

http://www.netcombo.com.br/internet-2

I found an easy tool to measure upload and download bandwidth: speedtest. It is not part of my Raspberry PI Debian Linux OS, so I had to install it first. After this I am able to check the upload rate and it comes close to the announced 2 Mbps.

Download and run

First step is to download speedtest.

Command:
wget -O speedtest-cli https://raw.github.com/sivel/speedtest-cli/master/speedtest_cli.py

Next is to make the file executable.

Command:
chmod +x speedtest-cli

Final step is to run the tool. It will automatically test the upload and download bandwidth.

Command: ./speedtest-cli

Result:

Download bandwidth is reprted at 14.5 Mbit and upload at 1.86 Mbit.

Is this enough to stream for instance audio? Command bit rate for MP3 is 128, 192 or 256 Kbps. That is Kilobits per second. 2 Mbps is 2 Mbit == 2000 Kilobits. This is way above 192 Kbps. Streaming audio should not be a problem.
