# # -- skip to main content raymii.org quis custodiet ipsos custodes? rss feed home all pages articles blog tutorials ansible openstack openvms pdp-8 monitoring ubuntu inception hosting affiliate link digital ocean affiliate link, $10 free credit. about hi there! i'm remy, a linux/unix sysadmin, my primary focus is on building high available cloud environments in openstack, amazon, microsoft azure or on premise with ansible and terraform (or any other configuration management tool). my keywords are openstack, cloud, virtualization, high availability, scaling and clustering, security, (open)ssl, python, powershell, bash and general linux/unix system administration. besides that i also develop software in python . i currently work for volkerwessels , the largest dutch civil engineering construction company as an (azure) cloud specialist. i've worked as a sysadmin (in a devops role) for the erasmus university medical center (a large hospital and medical university in rotterdam), digidentity (a dutch certificate authority , the company that develops digid and other ruby on rails applications), cloudvps (an openstack cloud provider, isp, managed service provider and datacenter) and a few other smaller companies. i like to design, build, document and manage large, complex and high available systems. i'm a team player that loves to work with configuration management tools and version control systems. if i do something more than three times i automate it. planning, documentation, monitoring and backups are things i do first, not when the time allows it later. last but not least i have an interest in legacy systems like the pdp-11, pdp-8 and operating systems like openvms, hp-ux and old unix systems. to contact me, see my resume, get my gpg or s/mime key see the about page . this is my personal website, please do note that these articles do not reflect or are based on work, opinions or policies of any of my (previous) employers. any resemblance to reality is pure coincidence. this site started in 2006 as my form of (public) documentation. it has grown to include software, tutorials, snippets and articles on linux/unix, system administration and everything related with over 10.000 unique visitors a day as of 2018-06 . the url is the phonetic way you say my name (ray-mii), since non-dutch speakers always have trouble with the correct pronunciation. latest items linux on microsoft azure? disable this built-in root-access backdoor (wa-linux-agent) 22-08-2018 | remy van elst are you running linux on microsoft azure? then by default anyone with access to your azure portal can run commands as root in your vm, reset ssh keys, user passwords and ssh configuration. this article explains what the backdoor (wa-linux-agent) is, what it is meant to do, how it can be disabled and removed and what the implications are. openstack/qemu also have an agent/backdoor which is covered in this article as well. read more... python script to talk to librenms api and get alerts and hosts 08-08-2018 | remy van elst this script talks to the librenms api to receive a list of down devices and alerts. the librenms dashboard provides widgets for alerts and host statusses, but there is no easy way to access that output via the api. using python i was able to get certain information and output it as html or text using prettytable. it can be included in other systems or be used in a chain of monitoring customizations. z read more... nginx 1.15.2, ssl_preread_protocol, multiplex https and ssh on the same port 06-08-2018 | remy van elst the nginx blog recently had a nice article on a new feature of nginx 1.15.2, $ssl_preread_protocol. this allows you to multiplex https and other ssl protocols on the same port, or as their blog states, 'to distinguish between ssl/tls and other protocols when forwarding traffic using a tcp (stream) proxy'. this can be used to run ssh and https on the same port (or any other ssl protocol next to https). by running ssh and https on the same port, one can circumvent certain firewall restrictions. if the session looks like https, nginx will handle it, if it looks like something else, it will forward it to the configured other program. i used to use sshl to get this functionality, but now it's built into the nginx webserver. this small guide will cover the installation of the latest version of nginx on ubuntu (16.04) and configuring this multiplex feature. read more... site updates for accessibility, text only pages and skip to main content 01-08-2018 | remy van elst i've made some new improvements to this website. raymii.org is generated using my self-written static site generator named ingsoc, the new features are focussed on accessibility. if you are using a screen reader or command-line browser this will benefit you. or if you like to archive stuff offline. the two main improvements are a text-only version of every content page (article/tutorial etc) and a 'skip to main content' link. read more... send email with multiple inline images via bash with a loop 23-07-2018 | remy van elst recently i had a request from a user that whished to receive a scheduled email with two screenshots. the screenshots were automated via autoit on a network share, the user manually logged in every evening to check the pictures. with bash and postfix/sendmail we can automate this process, the user now doesn't have to login but can just check their email. there are a lot of snippets and guides to attach emails via the shell, but displaying multiple images inline as an html mail was something i had to figure out. you cannot embed the image in base64 html because outlook doesn't show that, you must use the content-id style embed. like uuencode, but more complicated. (the next step in this process with the user is to automate the reason why they have to check those screenshots every night, that is something for another article) read more... log_vcs - ansible callback plugin that creates vcs (git) branches for every ansible run 10-07-2018 | remy van elst this ansible callback plugin creates a vcs branch every time you run ansible. if you ever need to go back to a certain state or environment, check out that branch and be sure nothing has changed. this is useful when you have multiple environments or multiple people deploying and continually develop your ansible. when you often deploy to test / acceptance and less often to production, you can checkout the last branch that deployed to production if a hotfix or other maintenance is required, without having to search back in your commits and logs. i would recommend to develop infrastructure features in feature branches and have the master branch always deployable to production. however, reality learns that that is not always the case and this is a nice automatic way to have a fallback. read more... windows 7 installer on a kvm linux vps (windows on digital ocean) 01-07-2018 | remy van elst for fun i wanted to install windows 7 on a kvm linux vps (on [digital ocean) but it should work for any kvm or xen-hvm vps with console access). i was experimenting with grub2 and iso booting, since grub2 can natively boot a linux iso. for windows this is not possible, the installer needs to be extracted on a fat32 partition from which you boot. on a normal system i would repartition the disk using a live cd, but on a vps where an iso cannot be booted this is troublesome. if i could boot from an iso i would use that to install windows, but where's the fun in that? i had to figure out how to shrink an ext4 filesystem from a running ubuntu vps, which is possible, however very risky, with pivot_root. next the partiton table can be converted to mbr, the partition can be resized, a fat32 partiton and filesystem can be created, the windows installer files copied onto that, some grub config and a reboot later, you're in the windows 7 installer. read more... syslog configuration for remote logservers for syslog-ng and rsyslog, both client and server 21-06-2018 | remy
