Yes, it is dumb that airports, stores, and hospitals run very outdated software, but imagine how hard it would be to upgrade all those machines, especially considering the programs that might not work well with never operating systems and the fact that staff would have to be trained all over again. Not to mention, most of these businesses and services can't afford any downtime and need to make sure that everything is compatible (so, update one PC, you have to update all of them). In theory, I am still a fan of updated systems, but then again, I have a 10 year old XP installation at home, which I've been preparing to reinstall for a year or so (don't really use that PC, but still)

Yesterday, microsoft showed me once again, what it means to "obey".

I tried to install Microsoft SQL Server 2012 on a virtual machine with OS Windows7.
The installation-center asked me to choose an installation-folder for SQL-Server.
No matter what, for any folder i had chosen for the installation, the setup replied with the errormessage "The installation-folder is invalid"

So i considered asking our platform-services team, whether they gave me administrative rights for the vm.
They did. I had full access to the components of my vm.

After a few days i finally recognized, that i had picked a wrong iso for the installation of sql server.

Instead of sql server 2012 + Service Pack 3, i picked sql server 2012 ServicePack 3.

So after all, Microsoft tried to tell me by showing the message "The installation-folder is invalid", that the setup weren't able to find an installation of Microsoft SQL Server 2012.

God damned!!1!

A client's site got malware infected, so we decided to remove everything and replace the site with a fresh WordPress installation (very basic site with 4 pages of content).

Contacted iPage live support asking them to check and unsuspend the account (with no files on it), but they kept on insisting that I buy their "firewall" and "SiteLock" services, with zero reply related to suspension. I've had live chat with many other hosting companies, never had such a lousy fucked up conversation. Without providing technical support, they keep marketing their useless expensive services. Fuck you iPage, you just lost a customer.

Alrighty, saturday morning rant time!

I just recieved a mail from one of my not-so-much-loved colleagues.

Now Background first: I work in IT-Support. We provide services for other companies. One of those services is monitoring servers and clients for various things. I recently took over the project (was assigned to do it) and restructured everything, wrote new scripts to test more stuff, successfully tested it internally and rolled it out over the last 2 weeks.

Now one of these scripts hooks into the Windows Update API and looks at the update history. It filters for known Windows Update Agent strings (UpdateOrchestrator, AutomaticUpdates and AutomaticUpdatesWuApp in case you also want to do something like this) and then looks for installation errors over the last 24 hours and wherever there have even been any successful updates over the last one and a half months.

Back to that mail.

My colleague sent me this lovely mail about a ticket i opened about his customers servers beeing all out-of-date on updates.

"This is all wrong, everything's fine. I disabled the checks."

...

It's on bitch.

So i logged on to my work PC via TeamViewer, opened my script, connected to the customer and was ready to debug the shit out of my script, knowing i probably won't even need to.

I looked at the update history via Windows Update itself and behold: 1st April. That's almost 50 days in the past.

So the script works, go figure.

Great, so search for new Updates then.
>None found.

Hm. What could it be? Did my super special colleague forget to care about his very special totally-needs-WSUS-customer WSUS again?

Yup.

Online-Search finds a ton of new Updates.

Screenshot, write pissed mail to colleague, re-enable checks, breakfast.

Fuck Oracle, fuck you oracle! The stupidest shittiest worst nightmare company with the most user-unfriendly, productivity-killing, illogical, stupid pile of software garbage products ever! And unfortunately I want to extends my worm-fucks to all Oracle employees and maintainers and to the whole fucking community of shit that made up oracle-community and to every conscious being who ever liked, enjoyed or have found the slightest genuine interest of any product tagged "oracle".

I installed the pile of shit a.k.a Oracle 18c and imported a dumb file locally, everything was working in the slightest amount of the word (fine) before it turns to nightmare. I created a C# client to call a stored procedure in that shit of a database engine. I kept getting error related to the parameter types, specifically one which is custom type of Table of numbers. It turns out that the only of doing this is through that shit they called (unmanaged driver), the "managed" doesn't support custom types. So I had to install another package of shit they call (odbc universal install) "universal my a$$ by the way", at that moment, where everything just crashed and stopped working. I spent 3 hours trying to connect to the fucking database to no avail. I shockingly found a folder in my desktop folder called (OracleInstallation) and all windows services related to oracle installation "suddenly" got somehow (re-routed) to that folder.
In conclusion, fuck oracle.

I've been wondering about renting a new VPS to get all my websites sorted out again. I am tired of shared hosting and I am able to manage it as I've been in the past.

With so many great people here, I was trying to put together some of the best practices and resources on how to handle the setup and configuration of a new machine, and I hope this post may help someone while trying to gather the best know-how in the comments. Don't be scared by the lengthy post, please.

The following tips are mainly from @Condor, @Noob, @Linuxxx and some other were gathered in the webz. Thanks for @Linux for recommending me Vultr VPS. I would appreciate further feedback from the community on how to improve this and/or change anything that may seem incorrect or should be done in better way.

1. Clean install CentOS 7 or Ubuntu (I am used to both, do you recommend more? Why?)
2. Install existing updates
3. Disable root login
4. Disable password for ssh
5. RSA key login with strong passwords/passphrases
6. Set correct locale and correct timezone (if different from default)
7. Close all ports
8. Disable and delete unneeded services
9. Install CSF
10. Install knockd (is it worth it at all? Isn't it security through obscurity?)
11. Install Fail2Ban (worth to install side by side with CSF? If not, why?)
12. Install ufw firewall (or keep with CSF/Fail2Ban? Why?)
13. Install rkhunter
14. Install anti-rootkit software (side by side with rkhunter?) (SELinux or AppArmor? Why?)
15. Enable Nginx/CSF rate limiting against SYN attacks
16. For a server to be public, is an IDS / IPS recommended? If so, which and why?
17. Log Injection Attacks in Application Layer - I should keep an eye on them. Is there any tool to help scanning?

If I want to have a server that serves multiple websites, would you add/change anything to the following?
18. Install Docker and manage separate instances with a Dockerfile powered base image with the following? Or should I keep all the servers in one main installation?
19. Install Nginx
20. Install PHP-FPM
21. Install PHP7
22. Install Memcached
23. Install MariaDB
24. Install phpMyAdmin (On specific port? Any recommendations here?)

I am sorry if this is somewhat lengthy, but I hope it may get better and be a good starting guide for a new server setup (eventually become a repo). Feel free to contribute in the comments.

#Suphle Rant 11: Laravel board launch

The launch took almost 2 weeks more than originally slated, because I sought to install it manually, just as an outsider would. Installation steps had been documented, automated tests for the installation tests were passing. When time came to actually execute the binary from the terminal, we went from one obstacle to the other. First, were the relatively minor Composer/Roadrunner issues, eventually resolved by the helpful RR maintainers who sat with me through a Discord server for about 2 hours until their command ran the way I needed it to.

Next was the Psalm scare: One of my value propositions was the guarantee of eliminating all type related bugs in Suphle apps. I intended to use Psalm for that. Wrote tests as usual. Turns out the library behaves differently under conditions differing from raw CLI usage. I resurrected threads I'd opened since December that were left unattended, and with some help from the maintainer, we eventually got it to do what I need it to do.

I was all the more frightened by the fact that Transphporm had caused me to renege on one of my earlier promises. I can only miss so many targets. After this, the docs had to be updated with all the changes effected to accurately integrate those two. Project installation and initialization commands were ran rigorously to ensure all progresses smoothly.

Tagged one final release and suddenly became impatient to launch on our local Laravel group chat where I've been a member for the last 4+ years, where we've had a rollercoaster of emotions. In that time, I've refined my launch speech to suit that audience -- obviously, countless times. Not just a tame "It's my pleasure to announce what I've been working on", but near 40 messages going into details about the inner workings, why it was built, how it compares. An expose that dove deeper than I would anywhere else.

I scheduled a time for them to tune in and got some encouraging anticipation. Ended up deflated after posting the whole thing. Only about 5 persons interacted. 1 (who I've chatted with outside the board) was quite enthusiastic. Feverishly checked the docs but commented it was overwhelming and he'd need more time. Already starred the repository.

For some context, there are give or take 250 members on that board. Not all are active but activity there easily reaches a crescendo when the topic discussed is about inanities like what 3rd party services to use for SMS, how to receive salaries from abroad, or job openings. I was optimistic when the acquaintance mentioned above published a payment library and met a riotuous welcome as one of their own. Maybe, they are simply not fond of me and the speech should have been passed off to someone else.

I checked Packagist installs -- not more 10. For 3 years, I'd been hyped up for that night; but for some reason, the audience I considered myself closest to flopped, woefully. Thankfully, this isn't the main launch. I'm still holding out hope for that. If it fails, I would have sunk an immeasurable amount of effort and time, that nobody will compensate me for. That is the one place I go to see those more advanced than me in PHP. I constantly learn there and find stimulating conversations there.

Now, I can no longer predict reception from other presentations. All I can do now is hope

Relatively often the OpenLDAP server (slapd) behaves a bit strange.

While it is little bit slow (I didn't do a benchmark but Active Directory seemed to be a bit faster but has other quirks is Windows only) with a small amount of users it's fine. slapd is the reference implementation of the LDAP protocol and I didn't expect it to be much better.

Some years ago slapd migrated to a different configuration style - instead of a configuration file and a required restart after every change made, it now uses an additional database for "live" configuration which also allows the deployment of multiple servers with the same configuration (I guess this is nice for larger setups). Many documentations online do not reflect the new configuration and so using the new configuration style requires some knowledge of LDAP itself.
It is possible to revert to the old file based method but the possibility might be removed by any future version - and restarts may take a little bit longer. So I guess, don't do that?

To access the configuration over the network (only using the command line on the server to edit the configuration is sometimes a bit... annoying) an additional internal user has to be created in the configuration database (while working on the local machine as root you are authenticated over a unix domain socket). I mean, I had to creat an administration user during the installation of the service but apparently this only for the main database...

The password in the configuration can be hashed as usual - but strangely it does only accept hashes of some passwords (a hashed version of "123456" is accepted but not hashes of different password, I mean what the...?) so I have to use a single plaintext password... (secure password hashing works for normal user and normal admin accounts).

But even worse are the default logging options: By default (atleast on Debian) the log level is set to DEBUG. Additionally if slapd detects optimization opportunities it writes them to the logs - at least once per connection, if not per query. Together with an application that did alot of connections and queries (this was not intendet and got fixed later) THIS RESULTED IN 32 GB LOG FILES IN ≤ 24 HOURS! - enough to fill up the disk and to crash other services (lessons learned: add more monitoring, monitoring, and monitoring and /var/log should be an extra partition). I mean logging optimization hints is certainly nice - it runs faster now (again, I did not do any benchmarks) - but ther verbosity was way too high.

The worst parts are the error messages: When entering a query string with a syntax errors, slapd returns the error code 80 without any additional text - the documentation reveals SO MUCH BETTER meaning: "other error", THIS IS SO HELPFULL... In the end I was able to find the reason why the input was rejected but in my experience the most error messages are little bit more precise.
