Managing more illumos networking with Ansible

On January 9th, the rest of my work on Ansible modules for managing Solaris/illumos networking was accepted into Ansible and this work will be a part of the next release. With this batch of modules almost every aspect of Solaris/illumos networking (apart from link aggregations and bridges) can be configured and managed by Ansible. The following new modules are available in Ansible: dladm_vlan dladm_linkprop dladm_iptun ipadm_addr ipadm_addrprop ipadm_ifprop In the next blog post I will show some real examples how to accomplish useful work with these modules.

33C3: Works for me

I visited 33rd Chaos Communication Congress, which took place between 27th and 30th December 2016 in CCH in Hamburg. The motto of last year’s congress was Works for me. This was my fifth attendance of the Chaos Communication Congress. The overall atmosphere on the Congress and organization was excellent as always. However, I have to admit that the quallity of talks was worse when compared to previous years. During previous Congresses I had problems with choosing which talk to attend as there were too many of them I wanted to visit at the same time.

Managing illumos networking with Ansible

On August 30th, my work on Ansible modules for managing Solaris/illumos networking was merged into ansible-modules-extras repository. This functionality will be available in the next release of Ansible. Following modules were contributed: dladm_etherstub dladm_vnic ipadm_if ipadm_prop flowadm This also marks a major milestone for automating the deployment of Solaris/illumos zones with Ansible. There already was a module for creating/deleting zones and manipulating their state - solaris_zone. However, there was not a way to manage the networking aspect of zones until now.

Mirroring OpenIndiana IPS repositories - part 1

Introduction In this blog post, I will show how one can create a mirror of OpenIndiana IPS repositories. IPS repositories hold packages coming from multiple sources, most notably from illumos-gate and oi-userland. Every time user runs pkg update on his OpenIndiana installation, pkg contacts IPS repository to fetch catalog metadata and determines if there are any new updates available. If updates are available, pkg downoalds only changed files over HTTP.

Migration from Octopress to Hugo

After a while, my blog finally received love it deserved. The biggest change is that I migrated the blog from Octopress to Hugo, which is a fast static site generator written in Go. The overall feeling stayed the same, but the blog maintenance is much easier for me. I am still finding my way around Hugo, but so far it works nicely. Another change is that this site is being hosted on Github Pages.

29c3: Finale

I arrived at CCH in the afternoon and headed directly for NOC Review talk. Guys did really wonderful job, although the Wifi was a problem. I really liked some network facts: ~70 access points, great signal coverage 3059 concurrent wireless clients connected during peaks traffic usage of 8.2 Gbps 40% of traffic being IPv6 Video can be found here. The 29C3 was really nice experience and I will definitely return back to 30C3.
