And here comes the last part of my story so far.
After deploying the domain, configuring PCs, configuring the server, configuring the switch, installing software, checking that the correct settings have been applied, configuring MS Outlook (don't ask) and giving each and every user a d e t a i l e d tutorial on using the PC like a modern human and not as a Homo Erectus, I had to lock my door, put down my phone and disconnect the ship's announcement system's speaker in my room. The reasons?
- No one could use USB storage media, or any storage media. As per security policy I emailed and told them about.
- No one could use the ship's computers to connect to the internet. Again, as per policy.
- No one had any games on their Windows 10 Pro machines. As per policy.
- Everyone had to use a 10-character password, valid for 3 months, with certain restrictions. As per policy.
For reasons mentioned above, I had to (almost) blackmail the CO to draft an order enforcing those policies in writing (I know it's standard procedure for you, but for the military where I am it was a truly alien experience). Also, because I never trusted the users to actually backup their data locally, I had UrBackup clone their entire home folder, and a scheduled task execute a script storing them to the old online drive. Soon it became apparent why: (for every sysadmin this is routine, but this was my first experience)
- People kept deleting their files, whining to me to restore them
- People kept getting locked out because they kept entering their password WRONG for FIVE times IN a ROW because THEY had FORGOTTEN the CAPS lock KEY on. Had to enter three or four times during weekend for that.
- People kept whining about the no-USB policy, despite offering e-mail and shared folders.
The final straw was the updates. The CO insisted that I set the updates to manual because some PCs must not restart on their own. The problem is, some users barely ever checked. One particular user, when I asked him to check and do the updates, claimed he did that yesterday. Meanwhile, on the WSUS console: PC inactive for over 90 days.
I blocked the ship's phone when I got reassigned.
Phiew, finally I got all those off my chest! Thanks, guys. All of the rants so far remind me of one quote from Dave Barry:

Paranoid Developers - It's a long one
Backstory: I was a freelance web developer when I managed to land a place on a cyber security program with who I consider to be the world leaders in the field (details deliberately withheld; who's paranoid now?). Other than the basic security practices of web dev, my experience with Cyber was limited to the OU introduction course, so I was wholly unprepared for the level of, occasionally hysterical, paranoia that my fellow cohort seemed to perpetually live in. The following is a collection of stories from several of these people, because if I only wrote about one they would accuse me of providing too much data allowing an attacker to aggregate and steal their identity. They do use devrant so if you're reading this, know that I love you and that something is wrong with you.
That time when...
He wrote a social media network with end-to-end encryption before it was cool.
He wrote custom 64kb encryption for his academic HDD.
He removed the 3 HDD from his desktop and stored them in a safe, whenever he left the house.
He set up a pfsense virtualbox with a firewall policy to block the port the student monitoring software used (effectively rendering it useless and definitely in breach of the IT policy).
He used only hashes of passwords as passwords (which isn't actually good).
He kept a drill on the desk ready to destroy his HDD at a moments notice.
He started developing a device to drill through his HDD when he pushed a button. May or may not have finished it.
He set up a new email account for each individual online service.
He hosted a website from his own home server so he didn't have to host the files elsewhere (which is just awful for home network security).
He unplugged the home router and began scanning his devices and manually searching through the process list when his music stopped playing on the laptop several times (turns out he had a wobbly spacebar and the shaking washing machine provided enough jittering for a button press).
He brought his own privacy screen to work (remember, this is a security place, with like background checks and all sorts).
He gave his C programming coursework (a simple messaging program) 2048 bit encryption, which was not required.
He wrote a custom encryption for his other C programming coursework as well as writing out the enigma encryption because there was no library, again not required.
He bought a burner phone to visit the capital city.
He bought a burner phone whenever he left his hometown come to think of it.
He bought a smartphone online, wiped it and installed new firmware (it was Chinese; I'm not saying anything about the Chinese, you're the one thinking it).
He bought a smartphone and installed Kali Linux NetHunter so he could test WiFi networks he connected to before using them on his personal device.
(You might be noticing it's all he's. Maybe it is, maybe it isn't).
He ate a sim card.
He brought a balaclava to pentesting training (it was pretty meme).
He printed out his source code as a manual read-only method.
He made a rule on his academic email to block incoming mail from the academic body (to be fair this is a good spam policy).
He withdraws money from a different cashpoint everytime to avoid patterns in his behaviour (the irony).
He reported someone for hacking the centre's network when they built their own website for practice using XAMMP.
I'm going to stop there. I could tell you so many more stories about these guys, some about them being paranoid and some about the stupid antics Cyber Security and Information Assurance students get up to. Well done for making it this far. Hope you enjoyed it.

Long rant ahead.. so feel free to refill your cup of coffee and have a seat 🙂
It's completely useless. At least in the school I went to, the teachers were worse than useless. It's a bit of an old story that I've told quite a few times already, but I had a dispute with said teachers at some point after which I wasn't able nor willing to fully do the classes anymore.
So, just to set the stage.. le me, die-hard Linux user, and reasonably initiated in networking and security already, to the point that I really only needed half an ear to follow along with the classes, while most of the time I was just working on my own servers to pass the time instead. I noticed that the Moodle website that the school was using to do a big chunk of the course material with, wasn't TLS-secured. So whenever the class begins and everyone logs in to the Moodle website..? Yeah.. it wouldn't be hard for anyone in that class to steal everyone else's credentials, including the teacher's (as they were using the same network).
So I brought it up a few times in the first year, teacher was like "yeah yeah we'll do it at some point". Shortly before summer break I took the security teacher aside after class and mentioned it another time - please please take the opportunity to do it during summer break.
Coming back in September.. nothing happened. Maybe I needed to bring in more evidence that this is a serious issue, so I asked the security teacher: can I make a proper PoC using my machines in my home network to steal the credentials of my own Moodle account and mail a screencast to you as a private disclosure? She said "yeah sure, that's fine".
Pro tip: make the people involved sign a written contract for this!!! It'll cover your ass when they decide to be dicks.. which spoiler alert, these teachers decided they wanted to be.
So I made the PoC, mailed it to them, yada yada yada... Soon after, next class, and I noticed that my VPN server was blocked. Now I used my personal VPN server at the time mostly to access a file server at home to securely fetch documents I needed in class, without having to carry an external hard drive with me all the time. However it was also used for gateway redirection (i.e. the main purpose of commercial VPN's, le new IP for "le onenumity"). I mean for example, if some douche in that class would've decided to ARP poison the network and steal credentials, my VPN connection would've prevented that.. it was a decent workaround. But now it's for some reason causing Moodle to throw some type of 403.
Asked the teacher for routers and switches I had a class from at the time.. why is my VPN server blocked? He replied with the statement that "yeah we blocked it because you can bypass the firewall with that and watch porn in class".
Alright, fair enough. I can indeed bypass the firewall with that. But watch porn.. in class? I mean I'm a bit of an exhibitionist too, but in a fucking class!? And why right after that PoC, while I've been using that VPN connection for over a year?
Not too long after that, I prematurely left that class out of sheer frustration (I remember browsing devRant with the intent to write about it while the teacher was watching 😂), and left while looking that teacher dead in the eyes.. and never have I been that cold to someone while calling them a fucking idiot.
Shortly after I've also received an email from them in which they stated that they wanted compensation for "the disruption of good service". They actually thought that I had hacked into their servers. Security teachers, ostensibly technical people, if I may add. Never seen anyone more incompetent than those 3 motherfuckers that plotted against me to save their own asses for making such a shitty infrastructure. Regarding that mail, I not so friendly replied to them that they could settle it in court if they wanted to.. but that I already knew who would win that case. Haven't heard of them since.
So yeah. That's why I regard those expensive shitty pieces of paper as such. The only thing they prove is that someone somewhere with some unknown degree of competence confirms that you know something. I think there's far too many unknowns in there.
Nowadays I'm putting my bets on a certification from the Linux Professional Institute - a renowned and well-regarded certification body in sysadmin. Last February at FOSDEM I did half of the LPIC-1 certification exam, next year I'll do the other half. With the amount of reputation the LPI has behind it, I believe that's a far better route to go with than some random school somewhere.25 -
That feeling when your client connection is more stable than the connection of a fucking game server... Incompetent pieces of shit!!! BEING ABLE TO PUT A COUPLE OF SPRITES DOESN'T MAKE YOU A FUCKING SYSADMIN!!!
Oh and I sent those very incompetent fucks a mail earlier, because my mailers are blocking their servers as per my mailers' security policy. A rant from the old box - their mail servers self-identify a fucking .local!!! Those incompetent shitheads didn't even properly change the values from test into those from prod!! So I sent them an email telling them exactly how they should fix it, as I am running the same MTA on my mailers (Postfix), at some point had to fix my mailers against the exact same issue as well, and clearly noticed in-game that they have deliverability problems (they explicitly mention to unblock their domain). Guess why?! Because their server's shitty configuration triggers fucking security mechanisms that are built against rogue mailers that attempt to spoof themselves as an internal mailer, with that fucking .local! And they STILL DIDN'T CHANGE IT!!!! Your fucking domain has no issues whatsoever, it's your goddamn fucking mail servers that YOU ASOBIMO FUCKERS SHOULD JUST FIX ALREADY!!! MOTHERFUCKERS!!!!!2 -
It's finally happened. I've used my mail servers for about a year to give out different email addresses on my domain to things I sign up for online, and only used my "actual" email address that received all this email for the whole domain but the single one that I used outbound for private communications.
This worked well for a long time as I could see when spam comes in, where it came from by looking at the email address I designated it. Each company's email would be sent not only from an email address that they choose, but also to an email address that I choose. It allowed me to easily determine where there were problems. For example, on Freenode IRC my vhost happened to make my username@host there a valid email address. It eventually got blacklisted due to too much incoming spam as crawlers started detecting it. Another one was "nickname"@my.domain as I posted it a few times here. Got crawled as well. But it allowed me to easily blacklist each.
I'd never thought my actual outbound email address, my real one, to get crawled though. That would require the mail server of a company I explicitly communicated with to get hacked. But today that happened. I wonder whose it is, but I can't tell.
Time to make my outgoing email bound to a designated email address as well. I want to know which companies this happens to, even if they don't disclose it.4 -
My first job was actually nontechnical - I was 18 years old and sold premium office furniture for a small store in Munich.
I did code in my free time though (PHP/JS mostly, had a litte browsergame back then - those were the days), so when my boss approached me and asked me whether I liked to take over a coding project, I agreed to the idea.
Little did I know at the time: I was supposed to work with a web agency the boss had contracted to build their online shop. Only that he had no plan or anything, he basically told them "build me an online shop like abc(a major competitor of ours at the time)"
He employed another sales lady who was supposed to manage the shop (that didn't exist yet). In the end, I think 80% of her job was to keep me from killing my boss.
As you can imagine, with this huuuuge amout of planning and these exact visions of what was supposed to be, things went south fast and far. So far that I could visit my fellow flightless birds down in the Penguin's republic of Antarctica and still need to go further.
Well... When my boss started suing the web agency, I was... ahem, asked to take over. Dumb as I was, I did - I was a PHP kid and thought that Magento, being written in PHP, would be easy to master. If you know Magento, you know that was maybe the wrongest thing I ever said.
Fast forward 3 very exhausting months, the thing was online. Not all of it worked yet, but it was online and fairly secure.
I did next to everything myself, administrating the CentOS box the shop was running on, its (own) e-mail server, the web server, all the coding required for the shop (can you spell 12 hour day for 8 hour pay?)
3 further months later, my life basically was a wreck, I dragged myself to work, the only thing I looked forward being the motorcycle ride home. The system worked though.
Mind you, I was still, at the time, working with three major customers, doing deskside support and some admin (Win Server 2008R2 at the time) - because, to quote my boss, "We could not afford a full time developer and we don't need one".
I think i stopped coding in my free time, the one hobby I used to love more than anything on the world, somewhere Decemerish 2012. I dropped out of the open source projects I was in, quit working on my browser game and let everything slide.
I didn't even care to renew the domains and servers for it, I just let it die without notice.
The little free time I had, I spent playing video games and getting drunk/high.
December 2013, 1.5 years on the job, I reached my breaking point and just left, called in sick at least a week per month because I just could not see this fucking place anymore.
I looked for another job outside of ALL of what I did before. No more Magento, no more sales, no more PHP. I didn't have to look for long, despite what I thought of my skills.
In February 2014, I told my boss that I quit. It was still seven months until my new job started, but I wanted him to know early so we could migrate and find a replacement.
The search for said replacement started in June 2014. I had considerably less work in the months before, looks like he got the hint.
In August 2014, my replacement arrived and I got him started.
I found a job, which I am still in, and still happy about after almost half a decade, at a local, medium sized ISP as a software dev and IT security guy. Got a proper training with a certificate and everything now.
My replacement lasted two months, he was external and never really did his job - the site, which until I had quit, had a total of 3 days downtime for 3 YEARS (they were the hoster's fault, not mine), was down for an entire month and he could not even tell why.
HIS followup was kicked after taking two weeks to familiarize himself with the project. Well, I think that two weeks is not even barely enough to familiarize yourself with nearly three years of work, but my boss gave him two days.
In 2016, the shop was replaced with another one. Different shop system, different OS, different CI. I don't know why and I can't say I give a damn.
Almost all the people that worked at the company back with me have left for greener pastures, taking their customers (and revenue) with them.
As for my boss' comments, instructions and lines: THAT might not be safe for work. Or kids. Or humans in general. And there wouldn't be much left if you put it through a language filter...
Moral of the story: No, it's not a bad thing to leave a place if you're mistreated there. Don't mistake loyalty with stupidity!
And, to quote one of my favourite Bands: "Nothing matters when the pain is all but gone" (Tragedy + Time by Rise Against).8 -
Hey there 👋
I am more or less throwing any burden (WhatsApp, Facebook, Google etc.) out of my life. Of course I will continue using the Google account for YouTube and some games that need it.
That's what it looks like right now:
Raspberry Pi 3B+
✅ webserver
- forum - complete (atm just for me)
- blog - no ideas and just installed october cms and nothing done yet
- nextcloud - complete and filled with my porn... eeh... data
✅ mailserver
(missing spamassassin, clam or sth. like this but it's working 😂)
✅ matrix-synapse
(as an additional alternative to messengers)
______________
Raspberry Pi 2
✅ catches dust
(any ideas?)
Of course, many more configurations and the like are necessary before everything is ready... but what then or what else is there?
At the moment I still use WhatsApp. Just wanna take time before sending everyone a message about changing the messenger and that it should be important for thinking about the own privacy, which alternatives there are bla...
Edit: For passwords I'm using Myki - didn't hear anything bad about it yet and it's very easy to use (Firefox add-on, Android app).
I love my passwords with 200 characters 😂
Maybe someone's knowing more about them?
Hope I didn't forget a thing... thanks in advance aaaaaaand... I'm gone. ☺23 -
Anything I (am able to) build myself.
Also, things that are reasonably standardized. So you probably won't see me using a commercial NAS (needing a web browser to navigate and up-/download my files, say what?) nor would I use something like Mega, despite being encrypted. I don't like lock-in into certain clients to speak some proprietary "secure protocol". Same reason why I don't use ProtonMail or that other one.. Tutanota. As a service, use the standards that already exist, implement those well and then come offer it to me.
But yeah. Self-hosted DNS, email (modified iRedMail), Samba file server, a blog where I have unlimited editing capabilities (God I miss that feature here on devRant), ... Don't trust the machines nor the services you don't truly own, or at least make an informed decision about them. That is not to say that any compute task should be kept local such as search engines or AI or whatever that's best suited for centralized use.. but ideally, I do most of my computing locally, in a standardized way, and in a way that I completely control. Most commercial cloud services unfortunately do not offer that.
Edit: Except mail servers. Fuck mail servers. Nastiest things I've ever built, to the point where I'd argue that it was wrong to ever make email in the first place. Such a broken clusterfuck of protocols, add-ons (SPF, DKIM, DMARC etc), reputation to maintain... Fuck mail servers. Bloody soulsuckers those are. If you don't do system administration for a living, by all means do use the likes of ProtonMail and Tutanota, their security features are nonstandard but at least they (claim to) actually respect your privacy.2 -
For all the hate that Java gets, this *not rant* is to appreciate the Spring Boot/Cloud & Netty for without them I would not be half as productive as I am at my job.
Just to highlight a few of these life savers:
- Spring security: many features but I will just mention robust authorization out of the box
- Netflix Feign & Hystrix: easy circuit breaking & fallback pattern.
- Spring Data: consistent data access patterns & out of the box functionality regardless of the data source: eg relational & document dbs, redis etc with managed offerings integrations as well. The abstraction here is something to marvel at.
- Spring Boot Actuator: Out of the box health checks that check all integrations: Db, Redis, Mail,Disk, RabbitMQ etc which are crucial for Kubernetes readiness/liveness health checks.
- Spring Cloud Stream: Another abstraction for the messaging layer that decouples application logic from the binder ie could be kafka, rabbitmq etc
- SpringFox Swagger - Fantastic swagger documentation integration that allows always up to date API docs via annotations that can be converted to a swagger.yml if need be.
- Last but not least - Netty: Implementing secure non-blocking network applications is not trivial. This framework has made it easier for us to implement a protocol server on top of UDP using Java & all the support that comes with Spring.
For these & many more am grateful for Java & the big big community of devs that love & support it. -

Someone posted a link to a 30-day-security-challenge here on devRant some time ago and I just thought well, why not try to migrate away from the big companies - I've been using OneDrive as my only cloudstorage since the time when it was called SkyDrive and I've been hosting my Emails at outlook (via Live Custom Domains, a service that does not even exist anymore) for about 8 years now. Since I've always been lazy and since exchange activesync is a great feature if you have multiple calendars and want to sync them and your contacts to several devices I never tried to switch but now I am half done with migrating my data to my own nextcloud installation and my emails to my own mail server - since I don't want to loose the exchange functionality I am also setting up Z-Push and oh boy, this thing is bitching around but my webmail is already nicely integrated into nextcloud, IMAP / SMTP is up, configured and secured (still have to mess around with spamassassin as this email adress is floating around the web for about 10 years now). The only things to do is to get Z-Push work with STARTTLS and the card/caldav backend running and then the basic setup should be done.
I am just wondering if someone could hand me over a guide on how to sign / encrypt emails (GPG?)
