While installing node.js : Error: Package: 1:nodejs-6.11.1-1.el7.x86_64 (epel) Requires: libhttp_parser.so.2()(64bit) Error: Package: 1:nodejs-6.11.1-1.el7.x86_64 (epel) Requires: http-parser >= 2.7.0 You can solve this by installing http_parser manually : yum install https://kojipkgs.fedoraproject.org//packages/http-parser/2.7.1/3.el7/x86_64/http-parser-2.7.1-3.el7.x86_64.rpm The reason behind the issue, is in that RHEL 7.4 now includes this package in the default repo, and for that reason its now removed from epel […]

I wanted to redo/rework the Passbolt install on Centos for a while. It’s seems like a horribly long and complex process, but in fact it’s not. With the recently released Passbolt 1.6 and my wish to play with asciinema for a while I thought why not combine both 🙂 Considering this is my first attempt, don’t shoot […]
It’s not the first time I received this error. It is the error you receive when the file (or large input in general) you tried to upload is too large and the server is declining it. Here is how you can fix it : Open your server {} specific config file for nginx : nano […]
I have some NFS servers (read: the main function is to store data and share it over NFS) to maintain and mostly they simply work (like everything in Linux). Most variables have been battle tested for … well forever. So rarely do you need to check on the best trade-off. Well enter the NFS thread […]
I recently learned about tcp_sack while I certainly don’t understand every detail of this feature, its clear it should be a huge help in cases where packets (in TCP protocol) are dropped and latency is relative high. From my basic understanding, when sending TCP protocol packages, every package has a number (sequence) when tcp_sack is […]
Woohoo, Proxmox VE 5.0 has been released, this version is based on Debian 9. (Linux Kernel 4.10) It includes allot of new features, but sadly updates are still pointing to the enterprise repository for updates. This results in ugly error message when trying apt-get update such as : W: The repository ‘https://enterprise.proxmox.com/debian/pve stretch Release’ does not […]
After reading cron.weekly a few weeks ago, I was intrigued by binsnitch.py, a tool that creates a baseline file with the md5/sha256/… hash of every file you wish to monitor. In case you think you have a virus, malware or cryptovirus you can verify easely what files have been changed. This is kinda fun, the […]

In the previous article on Bareos, we setup a quick and dirty backup job to run every night. This was pretty easy, but it has some flaws. (1) the first flaws, -after a full backup- only increment backups are created, forever. This makes it difficult to get a restore going down the line, as all the […]
