After fixing the concurrency issues, I started working on the features I mentioned initially. I began with the random-consistent-unique mode. I noticed the need for this in my manual review, and as discussed previously, this is definitely something that I think should be available. At the same time, this is implemented as a new mode […]
I have now started working on mmanon. As discussed in my previous post, before looking at any new features, I decided to give the AI code review a go. The results surprised me positively, as they were really useful. The AI found some concurrency issues, specifically regarding hash maps that different workers can access. These […]
It has been almost 10 years since I added my first commit to the mmanon module in rsyslog. In the meantime, I have kept myself busy with various university projects, though these were not really visible. Now, I want to avoid becoming rusty in terms of developing software, so I am getting back into the […]
After a long hiatus, I am planning to restart this blog. While different choices of platforms might be available, here are my reasons for continuing work on this blog. LinkedIn is slowly but surely becoming a common platform for posting information and content similar to the ones I plan to focus on this blog. However, […]
For some time, there has been a new repository for rsyslog and associated programs on OBS. There will be packages for more distributions than on the current official packages. We will add modules not available on the rsyslog site, for example omhttp. The link to download rsyslog packages from OBS is: https://software.opensuse.org//download.html?project=home%3Argerhards&package=rsyslog One reason […]
Currently we are working on new rsyslog packages using the SUSE OBS tool. While this is still experimental, we have now published the first batch of packages. You can find them here. We have decided to first focus on Debian, since there are no other rsyslog official packages for this distribution. However, these are still […]
As I said in my last post, I was working on making rainerscript functions into loadable modules. This had multiple reasons. For one, adding new functions may add more and more dependencies, which in the end takes up a lot of memory on your computer, even if you don’t plan on using any of the […]
Right now i am working on making rsyslog script functions loadable instead of statically built in at compile time. Currently, them being built in is not a problem as they do not have many dependenies. But as more functions get added, the bulk of dependencies required for script functions grows. One recent example is the […]
Apart from the normal format for IPv6, it is also possible to format an IPv6 with an embedded IPv4 instead of the last two blocks. This is described in the RFC 4291 section 2.2.3, for example:::FFFF:129.144.52.38 The format is used for systems working with both IPv6 and IPv4 addresses. However, in the RFC it is […]
As I mentioned in my recent post about the mmanon rewrite, I have been working on an offline anonymization tool. It is called SLFA (short for simple log file anonymizer) and I have now finished the first usable version. SLFA is a java application that allows you to anonymize files from the command line. Currently, […]
