tcpdump of a docker container

tcpdump of a docker container published on 2 Kommentare zu tcpdump of a docker container

You create docker containers and many tools are missing. As a example: tcpdump

So I was looking for a solution for sniffing the traffic from outside of the container. It is recommended to setup an additional (tcpdump) container and to use it with following network connection:

docker pull adamoss/docker-tcpdump

docker run -ti –net=container:${id} adamoss/tcpdump port https or port http

 

You can specify different ports and save the data in a file. The id is the name of the container and the „–net=container:“ is saying that you want to have input/output traffic of the docker container like the command would be executed on the same system.

openSUSE on ownCloud

openSUSE on ownCloud published on 7 Kommentare zu openSUSE on ownCloud

It is Christmas time and I have got cookie cutters by openSUSE and ownCloud. What can you create as a happy Working Student at ownCloud and an openSUSE Contributor?

Normally you deploy ownCloud on openSUSE. But do you know the idiom „to be in seventh heaven“ (auf Wolke 7 schweben)?

I want to  show you openSUSE Leap 42.2 on ownCloud 9.

 

opensuse Leap 42.2 on owncloud 9
opensuse Leap 42.2 on ownCloud 9

9.1 is the latest release, and 7 not up to date and insecure for the openSUSE chameleon. The second reason is that the chameleon has got a perfect place on the cloud.

You can watch the success in both projects!

I wish you all a merry christmas and a lot of fun with your cookie cutters!

Arriving in Brussels for FOSDEM

Arriving in Brussels for FOSDEM published on Keine Kommentare zu Arriving in Brussels for FOSDEM

Today I left the company a little bit earlier for getting the train to Brussels.

What for a surprise! A ex colleague of 1&1, who works as an architect, was sitting across from me since Mannheim. We told us about the changes in the last years, what would be new and what we want to have in the future. We had to wait for the next train in Cologne for a 3/4 hour. We used this time for eating. We met another ex colleague, who is a freelancer now. WE spoke about Cologne and the life there. I have lived 8 years of my childhood in this town.

We began a discussion about good literature for Computer Science and getting DevOps into a company:

-The most important book for learning programming and algorithms in theory is Introduction to Algorithms. You can find additional videos matching to the book on the homepage of the MIT.

-I go to every presentation of the Java User Group Karlsruhe. Many companies are working on the base of Clean Code. That’s the practical part for good programming. Every programmer should read this book.

-You can learn operations with an own server at home or with training on the job in companies. I have taken the first way during my education as a Computer Science Expert and have got a job as a Junior Linux System Administrator at 1&1 after that. That was a big jump for me and I enjoyed my junior time. Our team has got the specialization „Monitoring & Infrastructure“. We were Sysadmins for the root monitoring system, the customer DNS and the internal DNS. I wanted to learn more and switched to an international provider for MRM systems. We are a small business, but the leader on the European market. I was responsible for all in the system administration of our customer systems. Different Open Source Software is integrated into our software and working in this area of Cloud Computing is part of Big Data. You can have fun there and grow.

The combination of all is a dream…

We took different ways after arriving Brussels. I went to the hotel Evergreen. I thought, that would be a good idea for bowing out of Evergreen in openSUSE. We‘ ll miss this project.

 

I am looking forward to see many familiar faces at the FOSDEM.
