Started working on a pihole alternative a while ago.
I like pihole a lot but one of the features I am missing is to be able to define a list of mass surveillance related domains (Snowden leaks; PRISM program and such) and show statistics based on dns queries containing blacklisted domains, prases/words and surveillance-related domains/words (google/facebook/microsoft/apple etc).
Started working on one based on an existing (php based) dns server which is open source and slowly but surely developed something which worked.
Then, I found out that the php resolving function (dns resolving) uses the system default, which can, of course, be google's dns as well. Changing this would be ideal but while the documentation suggested that it could be done some way, it didn't work for me so I chose a library which can do it with specific dns servers (to use as external dns servers).
This library used a different way of showing the retrieved dns query results and really wasn't in for converting everything by hand so i kinda quit the project a while ago.
A few days ago I thought fuck it and started again.
Now have a working version based on the new dns resolving library and made some other good improvements.
For those who are wondering why I chose PHP for this: why the fuck not?
Happy happy happy.rant php fuck mass surveillance fuck microsoft fuck google dns server yes i love php fuck facebook dns18 -
For the last week or so I've been writing a userbot for Telegram. Completely from scratch, plus Telethon to not reinvent the wheel entirely. I'm coming from the codebase of an existing userbot.
That userbot is written by a good friend of mine, who makes 6 figures, and whom I respect greatly. However the code is a steaming pile of shit. Now that is not his fault, he largely inherited that code too, tried to fix it, failed, gave up.
I am reimplementing it entirely. I'm only looking at the modules, trying to understand them, and copying over the necessary bits and changing them where necessary. But I've come across some nasty shit.
Userbots often edit existing messages from real Telegram clients. They're kind of like a login to your account, but with a program rather than a regular client. You send a message from a real client, it sees it and does whatever it needs to, and edits your message to give you feedback. Which is great.
However, there's no need to do simple string edits by importing "re". So why do you? Because you're an idiot, that's why. The old bot is based on Paperplane, which in turn is based on Telethon. Why do I see function calls to Telethon in some places and Paperplane in others? Because you're an idiot, that's why. Why does the dig module fail to even give correct answers? Because you know nothing about the DNS, that's why. And you didn't learn about RRs before implementing it.
And don't you tell me that this code is shit, and this bot is slow only when I run it on a fucking Pentium. I run this shit on an i7 and CPU isn't even the issue - memory, disk and such are. If you had any clue whatsoever about efficiency, you would've known because it's blatantly obvious. There's a reason why my machines rarely go past 5% CPU utilization. It's the fastest component in the entire fucking system.
When users come and say.. hmm this application of yours, it consumes a lot of memory. It takes a long time to do X and Y and I don't quite understand why, it seems illogical. Then maybe you should go look at your code, like you would look at yourself in the mirror. And then you fucking go fix it so that I don't have to. You're an engineer just like I am. And I am not even a dev proper - I'm a sysadmin by trade. Why should I have to fix your shit for you?1 -
Either CloudFlare itself has decided to join the fun of attacking my DNS server, or somebody is just spoofing their IP in the UDP packets.
Crap, my ipset script is basically useless now, since the real source could be from anywhere :(
Any suggestions on what could I do to make this attack stop? It's not causing any real issues (at least for now), but it's still annoying as hell.
Get fucked, stupid skiddie who keeps manually changing the ip source in his script10 -
My god do I hate changing DNS settings. Spent an hour double and tripple checking everything and reading documentation. Was super stressed the entire time. Still ended up with a misconfiguration and 15 minutes downtime. But things seem to be working now.2

I have just slept for a minimum of 5 hours. It is 7:47 PM atm.
Why?
We have had a damn stressful day today.
We have had a programming test, but it really was rather an exam.
Normally, you get 30 minutes for a test and 45 minutes for an exam.
In this "test" we have had to explain what 'extends' does and name a few advantages of why one should use it.
Check.
Read 3 separate texts and write the program code on paper. It was about 1 super class and 1 sub class with a test class in Java.
Check.
Task 3: Create the UML diagram of the code from above. *internally: From above? He probably means my code since there is no other code there. *Checks time*. I have about 3 minutes left. Fuck my life.*
Draws the boxes. Put the class names in each of them. A private attribute for the super class.
Teacher: Last minute!
Draw the arrow starting starting from the sub class to the super class.
Put my name on each written paper. And mentally done for the day. Couldn't finish the last task. Task 3.
During this "test", I heard the frustrations of my classmates. Seemed like everyone was pretty much pissed.
After a short discussion with the teacher who also happens to be the physics professor of a university nearby.
[If you are reading this, I hope that something bad happens to you]
The next course was about computer systems. Remember my recent rant about DNS, dhcp, ftp, web server and samba on ubuntu?
We have had the task to do the screenshots of the consoles where you proof that you have dhcp activated on win7 machine etc. Seemed ok to me. I would have been done in 10 minutes, if I would be doing this relaxed. Now the teacher tells us to change the domain names to <surnameOfEachStudent>.edu.
I was like: That's fine.
Create a new user for the samba server. Read and write directories. Change the config.
Me: That should be easy.
Create new DNS entries in the configs.
Change the IPv6 address area to 192.168.x.100-200/24 only for the dhcp server.
Change the web server's default page. Write your own text into it.
You will have 1 hour and 30 minutes of time for it.
Dumbo -ANGRY-CLIENT-: Aye. Let us first start screenshotting the default page. Oh, it says that we should access it with the domain name. I don't have that much time. Let us be creative and fake it, legally.
Changes the title element so that it looks like it has been accessed via domain name. Deletes the url and writes the domain name without pressing Enter. Screenshot. Done. Ok, let us move to the next target.
Dhcp: Change lease time. Change IP address area. Subnet mask. Router. DNS. Broadcast. Optional domain name. Save.
Switches to win7.
ipconfig /release
ipconfig /renew
Holy shit it does not work!
After changing the configs on ubuntu for a legit 30 minutes: Maybe I should change the ip of the ubuntu virtual machine itself. *me asking my old self: why did not you do that in the first place, ass hole?!*
Same previous commands on win7 console. Does not work. Hmmm...
Where could be the problem?
Check the IP of the ubuntu server once again. Fml. Ubuntu did not save when I clicked on the save button the first time I have changed it. Click on save button 10 times to make sure it really is saved now lol.
Same old procedure on win7.
Alright. Dhcp works. Screenshot.
Checks time. 40 minutes left.
DNS:It is your turn. Checks bind9 configs. sudo nano db.reverse.edu.
sudo nano db.<mysurname>.edu.
Alright. All set. It should work now.
Ping win7 from ubuntu and vice versa. Works. Ping domain name on windows 7 vm. Does not work.
Oh, I forgot to restart the bind9 server on ubuntu.
sudo service bind stop
" " " start
Check DNS server IP on win7. It looks fine.
It still doesn't work. Fuck it. I have only 20 minutes left. Samba. Let us do this!
10 minutes in. No result. I don't remember why. I already forgot why I have done for it. It was a very stressful day.
Let us try DNS again.
Oh shit. I forgot the resolver!
sudo nano /etc/resolv.conf
The previous edits are gone. Dumb me. It says it in the comments. Why did not I care about it. Fuck it.6 minutes left. Open a yt video real quick. Changes the config file. Saves it. Restarts DNS and dhcp. Closes the terminal and opens a new one. The changes do not affect them until you reopen them. That's why.
Change to win7.
Ping works. How about nsloopup.
Does not work.
Teacher: 2 minutes left!
Fuck it.
Saves the word document with the images in it. Export as pdf. Tries to access the directories of the school samba server. Does not work. It was not my fault tho. Our school server is in general very slow. It feels like they are not maintained and left alone like this in the dust from the 90s.
Friend gets the permission to put his document on a USB and give the USB to the teacher.
Sneaky me: Hey xyz, can you give me your USB real quick?
Him: sure.
Gets bombed with "do you want to format the USB?" pop-ups 10 times. Fml. Skips in a fast way.
Transfers the pdf. Plug it out. Give it back.
After this we have had to give a presentation in politics. I am done.6 -
I think I finally, really, comprehend why secret societies have historically been created... I mean the potentially logical ones. This train of thought is logically terrifying.
I want a logic check.
I've been jokingly mentioning some of my totally true, practically useless in most scenarios, skills/specific fields of knowledge/ability under a moniker of 'extremely useful, assuming apocalyptic event' for years. Things like advanced knowledge of Coefficients of glass expansion, Fortran, various things that have caused friends to refer to me as MacGyver after the reboot came out.
In recent years, I've personally encountered several varieties of the ones defined by helplessness, self-victimisation, some version of a real disability... that theyve expounded into a personified personal nemesis-- to flashily battle yet never overcome, etc... the vast majority perplexing me as to why that's a valid form of life to them... it's not that they never consider some other way; the ball is just quickly dropped and never picked back up.
College?(not that I'm a big fan) they wish they could but so expensive... aide? The form was hard/confusing/past-due...
Lookup/learn something more indepth than a tiktok? *some self-deprecating bs*
Yet it's "I always wanted to do/be/learn X"
Shows like 'How It's Made' fascinate, but don't inspire enough for a 5min google query.
In the dev world its a clear, inverted pyramid-- one of the first posts I saw when I rejoined here was ostream's rant on Apple sucking because after they stop support/updates you "can't" load a different OS... ofc you can. But several comments down... no mention of that... i think it was @LensFlare who was the only one in ~15 respondents to point out the core logical fallacy.
Basic shit is totally forgotten... try asking some random adults what plastic is made from... or pay attention to how many people declare they have a gluten "allergy".
I get people frequently telling me that things im pointing out as differences don't matter because "it's just semantics"... semantics is literally the epitome of "significance", with roots in 'meaning' and 'truth'
Back to the main issue... We are in a world where DIY is typically something you pay more to do as a catered experience than actually learning anything, people destroy their own arguments hopes of validity unwittingly often by stating the arguement, get 'offended' or 'triggered' by factual statements, propagate misinformation and bastardise words until MW needs money enough to print a new version, likely adding the misuse as an actual definition and basic knowledge and the thought to actually learn is vetoed by the existence of google translate, the wisdom of tiktok and the pure brillance of troubleshooting every random linux issue you have from not knowing basic CLI and thinking linux makes you cool, with chmod 777 because so many other dumbasses on forums keep propagating misinformation. Ask them what 777 means, most have no clue... as they didnt consider googling that one before putting it in a terminal several times.
The number of humans that actually know the basic shit that the infrastructure of the world is built on keeps decreasing... and we aren't even keeping a running tally.
The structure of the internet has the right idea... dns- 13 active master root servers, with multiple redundancies if they start dropping... hell ICANN is like a secret society but publicly known/obfuscated... the modern internet hasnt had a global meltdown... aside from the lack of censorship and global availability changing the social definition of a valid use of braincells to essentially propagating spam as if it's factual and educational.
So many 'devs' so few understanding what a driver is, much less how to write one... irl network techs that don't know what dhcp is or that their equiptment has logs... professionals in deducated fields like Autism research/coping... no clue why it was called "autism", obesity and malnutrition simultaneously existing in the same humans... it's like we need to prepare a subterranean life-supporting vault and stock it like Noah's ark... just including the basic knowledge of things that used to be common/obvious. I've literally had 2 different, early 20s, female, certified medical assistants taking my medical history legitimately ask if not having a uterus made it harder to get pregnant...i wish i was joking.
Any ideas better than a subterranean human vault system? It's not like we can simply store detailed explanations, guides, media... unless we find a way to make them into obfuscated tiktok videos apparently on nonsense or makeup tutorials.11 -
My internet connection is so messed up. Again certain websites are not loading on my Mac but they are loading on my phone using WiFi. I tried clearing cookies, flushing DNS cache and changing DNS servers to OpenDNS or Google DNS.8
-
Just out of curiosity...
Is there a way to prevent a DDoS attack using settings in the Router? Like, changing the DNS Port to maybe 54 because most people just spam 53 with random packets?5 -
Anyone know of a way of viewing DNS records that show CNAME entries. Usually they get followed and omitted, which can be a problem when changing Nameservers and you don’t have domain control on the original server.3

I am not sure what's wrong but from this evening I can only access Google's sites + some other site using my WiFi but can't access devRant + other tons of site
Tried to reset the router, tried changing the DNS addresses, tried using VPN but nothing worked2
