Possibly outdated!

This article is possibly outdated. It mentions an older version of a software or tool. I haven't checked if the links are still working!

IBM sold their collaboration tools portfolio to HCL Software in 2019, so the product names changed and most of the IBM links are no longer working.

Nach meinem kompletten Umstieg auf Linux fand ich u.a. noch eine ppk-Datei die ich ssh-Verbindungen benutze.

Da ich unter Ubuntu nicht mehr mit putty arbeiten wollte, suchte ich nach einer Möglichkeit, diesen Key in einen RSA-Key umzuwandeln.

apt-get install puttygen

puttygen key.ppk -o id_rsa.pub -O public-openssh

puttygen key.ppk -o id_rsa -O private-openssh

I work at Vegard IT GmbH as a senior consultant with a focus on collaboration software, Kubernetes, security and automation. I mainly deal with HCL Connections, WebSphere Application Server, Kubernetes, Ansible, Terraform and Linux.

Sometimes my daily work results in technical talks and blog articles, which you can follow here more or less regularly. You can find the presentations in the main menu under public speaking .

I created a list of tools I use regularly, most of which have been released under an open source license.

In my spare time I read a lot, test all kinds of technical software and gadgets and try to follow about 200 RSS feeds.
Here you can find a collection of them.
