Most routers/switches out there store their configuration in plain text, which is nice for backups. I’m talking about Cisco, Juniper, HPE, etc. The configuration of our routers are being changed several times a day by the operators, and in this case we lacked some proper way of tracking these changes.
Some of these routers come with their own mechanisms for doing backups, and depending on the model and version perhaps they include changes-tracking mechanisms as well. However, they mostly don’t integrate well into our preferred version control system, which is
Debian has many years of history, about 25 years already. With such a long travel over the continuous field of developing our Universal Operating System, some myths, false accusations and bad reputation has arisen.
Today I had the opportunity to discuss this topic, I was invited to give a Debian talk in the “11º Concurso Universitario de Software Libre”, a Spanish contest for students to develop and dig a bit into free-libre open source software (and hardware).
Debian Stretch stable includes the nftables framework, ready to use. Created by the Netfilter project itself, nftables is the firewalling tool that replaces the old iptables, giving the users a powerful tool.
Back in October 2016, I wrote a small post about the status of ntables in Debian Stretch. Since then, several things have improved even further, so this clearly deserves a new small post :-)
Debian Stretch feels like an excellent release by the Debian project. The final stable release is about to happen in the short term.
Among the great things you can do with Debian, you could set up a VPN using the openvpn software.
In this blog post I will describe how I’ve deployed myself an openvpn server using Debian Stretch, my network environment and my configurations & workflow.
Today I ended reading an interesting article by the 4th spanish ISP regarding IPv6 and CGNAT. The article is in spanish, but I will translate the most important statements here.
Having a spanish Internet operator to talk about this subject is itself good news. We have been lacking any news regarding IPv6 in our country for years. I mean, no news from private operators. Public networks like the one where I develop my daily job has been offering native IPv6 since almost a decade…
Great news! The Netfilter project has been elected by Google to be a mentoring organization in this year Google Summer of Code program. Following the pattern of the last years, Google seems to realise and support the importance of this software project in the Linux ecosystem.
I will be proudly mentoring some student this 2017 year, along with Eric Leblond and of course Pablo Neira.
I was wrong. After the other blog post About process limits, some people contacted me with additional data and information. I myself continued to investigate on the issue, so I have new facts.
I read again the source code of the slapd daemon and the picture seems clearer now.
The other day I had to deal with an outage in one of our LDAP servers, which is running the old Debian Wheezy (yeah, I know, we should update it).
We are running openldap, the slapd daemon. And after searching the log files, the cause of the outage was obvious:
Debian is very difficult, a puzzle. This surprising statement was what I got last week when talking with a group of new IT students (and their teachers).
I would like to write down here what I was able to obtain from that conversation.
The year 2016, which is about to end, has been full of work and contributions to the FLOSS comunity.
Most of my focus goes to two important projects: Debian and Netfilter. This is no coincidence, since my main interests in the IT world are systems and networks.
There are about 15 Netfilter packages in Debian, and they are maintained by separate people.
Yersterday, I contacted the maintainers of the main packages to propose the creation of a pkg-netfilter team to maintain all the packages together.
Last week we had an interesting Debian meeting in Seville, Spain. This has been the third time (in recent years) the local community meets around Debian.
The next Debian stable release is codenamed Stretch, which I would expect to be released in less than a year.
The Netfilter Project has been developing nftables for years now, and the status of the framework has been improved to a good point: it’s ready for wide usage and adoption, even in high-demand production environments.
The moment has come. You may contact me now at firstname.lastname@example.org :-)
After almost 6 months of tough NM process, the waiting is over. I have achieved the goal I set to myself back in 2011: become Debian Developer.
This is a professional and personal victory.
People keep ignoring the status of the Pacemaker HA stack in Debian Jessie. Most people think that they should stick to Debian Wheezy.
Why does this happen? Perhaps little or none publicity of the situation.
Since some time now, Debian contains a Pacemaker stack which is ready to use in both Debian Jessie and in Debian Stretch.
