The ability to slap people through tcp/ip.

--- HTTP/3 is coming! And it won't use TCP! ---

A recent announcement reveals that HTTP - the protocol used by browsers to communicate with web servers - will get a major change in version 3!

Before, the HTTP protocols (version 1.0, 1.1 and 2.2) were all layered on top of TCP (Transmission Control Protocol).
TCP provides reliable, ordered, and error-checked delivery of data over an IP network.
It can handle hardware failures, timeouts, etc. and makes sure the data is received in the order it was transmitted in.
Also you can easily detect if any corruption during transmission has occurred.
All these features are necessary for a protocol such as HTTP, but TCP wasn't originally designed for HTTP!
It's a "one-size-fits-all" solution, suitable for *any* application that needs this kind of reliability.
TCP does a lot of round trips between the client and the server to make sure everybody receives their data. Especially if you're using SSL. This results in a high network latency.
So if we had a protocol which is basically designed for HTTP, it could help a lot at fixing all these problems.
This is the idea behind "QUIC", an experimental network protocol, originally created by Google, using UDP.

Now we all know how unreliable UDP is: You don't know if the data you sent was received nor does the receiver know if there is anything missing. Also, data is unordered, so if anything takes longer to send, it will most likely mix up with the other pieces of data. The only good part of UDP is its simplicity.
So why use this crappy thing for such an important protocol as HTTP?
Well, QUIC fixes all these problems UDP has, and provides the reliability of TCP but without introducing lots of round trips and a high latency! (How cool is that?)

The Internet Engineering Task Force (IETF) has been working (or is still working) on a standardized version of QUIC, although it's very different from Google's original proposal.
The IETF also wants to create a version of HTTP that uses QUIC, previously referred to as HTTP-over-QUIC. HTTP-over-QUIC isn't, however, HTTP/2 over QUIC.
It's a new, updated version of HTTP built for QUIC.

Now, the chairman of both the HTTP working group and the QUIC working group for IETF, Mark Nottingham, wanted to rename HTTP-over-QUIC to HTTP/3, and it seems like his proposal got accepted!
So version 3 of HTTP will have QUIC as an essential, integral feature, and we can expect that it no longer uses TCP as its network protocol.

We will see how it turns out in the end, but I'm sure we will have to wait a couple more years for HTTP/3, when it has been thoroughly tested and integrated.

Thank you for reading!

I'm pretty sure it was already posted in here, but I found it today

Did you get it?

So I decided to give Linux a try again.

Created live usb. Prepared myself to go through all the hassles at the beginning.

Booted in live USB. I can't see mouse cursor.

Searched in google, apparently a common problem with GTX 1070/1080 graphics cards.

Installed proprietary nvidia drivers with keyboard only. Took me about 20 minutes.

Finally managed to get the mouse cursor and install ubuntu. Time to boot and smell the fresh air of linux again.

Sound card doesn't work. Even the integrated mobo sound card doesn't work. Looked for a solution, found the bug in lunchpad but not solution yet. Everyone recommending to buy an external sound card.

I can't code without music. Decided to remove linux.

Booted back to Windows and removed linux partition. That fucked up my bootloader although I installed linux's efi loader completely separately.

Now I am sitting in front of my computer, with black grub screen, while trying to make a Windows 10 usb with my 7 years old broken laptop.

Next time I see a rant about Windows 10 that glorifies linux, I swear I'm gonna smack your face over standard TCP/IP

So this was a couple years ago now. Aside from doing software development, I also do nearly all the other IT related stuff for the company, as well as specialize in the installation and implementation of electrical data acquisition systems - primarily amperage and voltage meters. I also wrote the software that communicates with this equipment and monitors the incoming and outgoing voltage and current and alerts various people if there's a problem.

Anyway, all of this equipment is installed into a trailer that goes onto a semi-truck as it's a portable power distribution system.

One time, the computer in one of these systems (we'll call it system 5) had gotten fried and needed replaced. It was a very busy week for me, so I had pulled the fried computer out without immediately replacing it with a working system. A few days later, system 5 leaves to go work on one of our biggest shows of the year - the Academy Awards. We make well over a million dollars from just this one show.

Come the morning of show day, the CEO of the company is in system 5 (it was on a Sunday, my day off) and went to set up the data acquisition software to get the system ready to go, and finds there is no computer. I promptly get a phone call with lots of swearing and threats to my job. Let me tell you, I was sweating bullets.

After the phone call, I decided I needed to try and save my job. The CEO hadn't told me to do anything, but I went to work, grabbed an old Windows XP laptop that was gathering dust and installed my software on it. I then had to build the configuration file that is specific to system 5 from memory. Each meter speaks the ModBus over TCP/IP protocol, and thus each meter as a different bus id. Fortunately, I'm pretty anal about this and tend to follow a specific method of id numbering.

Once I got the configuration file done and tested the software to see if it would even run properly on Windows XP (it did!), I called the CEO back and told him I had a laptop ready to go for system 5. I drove out to Hollywood and the CFO (who was there with the CEO) had to walk about a mile out of the security zone to meet me and pick up the laptop.

I told her I put a fresh install of the data acquisition software on the laptop and it's already configured for system 5 - it *should* just work once you plug it in.

I didn't get any phone calls after dropping off the laptop, so I called the CFO once I got home and asked her if everything was working okay. She told me it worked flawlessly - it was Plug 'n Play so to speak. She even said she was impressed, she thought she'd have to call me to iron out one or two configuration issues to get it talking to the meters.

All in all, crisis averted! At work on Monday, my supervisor told me that my name was Mud that day (by the CEO), but I still work here!

Here's a picture of the inside of system 8 (similar to system 5 - same hardware)

A tcp packet walks in to a bar and says “I want a beer”, barman says “you want a beer?” and tcp packet says “yes, a beer” .

In high society, TCP is more welcome than UDP. At least it knows a proper handshake.

A bunch of TCP packets go into a bar, until it’s overcrowded. The next day, half as many go in.

A bunch of TCP packets walk into a bar. The bartender says, “Hang on just a second, I need to close the window.”

When I try to send SYNs to chicks, I don’t get any ACKs. Just FINs and RSTs.

IP packet with TTL=1 arrives at bar. Bartender: “Sorry, can’t let you leave…and you don’t get any beer either…” 

The worst part about token ring jokes is that if someone starts telling one while you are telling yours, all joking stops.

The great thing about TCP jokes is that you always get them.

The problem with TCP jokes is that people keep retelling them slower until you get them.

I would tell some UDP jokes too but I never know if anyone gets them

The best thing about UDP jokes is that I don’t care if you get them or not.

I had a funny UDP joke to tell, but I lost it somewhere...

The sad thing about IPv6 jokes is that almost no one understands them and no one is using them yet.

I tried to come up with an IPv4 joke, but the good ones were all already exhausted.

A DHCP packet walks into a bar and asks for a beer. Bartender says: “here, but I’ll need that back in an hour!

DHCP jokes only work when there is only one person telling them

The worst part of SSH jokes is that, even when they're not funny, you suck it up and just pretend they were anyway.

The problem with token ring jokes is you need to wait your turn to laugh

I’d make a joke about UDP, but I don’t know if anyone’s actually listening…

Navy story time, and this one is lengthy.
As a Lieutenant Jr. I served for a year on a large (>100m) ship, with the duties of assistant navigation officer, and of course, unofficial computer guy. When I first entered the ship (carrying my trusty laptop), I had to wait for 2 hours at the officer's wardroom... where I noticed an ethernet plug. After 15 minutes of waiting, I got bored. Like, really bored. What on TCP/IP could possibly go wrong?
So, scanning the network it is. Besides the usual security holes I came to expect in ""military secure networks"" (Windows XP SP2 unpatched and Windows 2003 Servers, also unpatched) I came along a variety of interesting computers with interesting things... that I cannot name. The aggressive scan also crashed the SMB service on the server causing no end of cute reactions, until I restarted it remotely.
But me and my big mouth... I actually talked about it with the ship's CO and the electronics officer, and promptly got the unofficial duty of computer guy, aka helldesk, technical support and I-try-to-explain-you-that-it-is-impossible-given-my-resources guy. I seriously think that this was their punishment for me messing around. At one time I received a call, that a certain PC was disconnected. I repeatedly told them to look if the ethernet cable was on. "Yes, of course it's on, I am not an idiot." (yea, right)
So I went to that room, 4 decks down and 3 sections aft. Just to push in the half-popped out ethernet jack. I would swear it was on purpose, but reality showed me I was wrong, oh so dead wrong.
For the full year of my commission, I kept pestering the CO to assign me with an assistant to teach them, and to give approval for some serious upgrades, patching and documenting. No good.
I set up some little things to get them interested, like some NMEA relays and installed navigation software on certain computers, re-enabled the server's webmail and patched the server itself, tried to clean the malware (aka. Sisyphus' rock), and tried to enforce a security policy. I also tried to convince the CO to install a document management system, to his utter horror and refusal (he was the hard copy type, as were most officers in the ship). I gave up on almost all besides the assistant thing, because I knew that once I left, everything would go to the high-entropy status of carrying papers around, but the CO kept telling me that would be unnecessary.
"You'll always be our man, you'll fix it (sic)".
What could go wrong?
I got my transfer with 1 week's notice. Panic struck. The CO was... well, he was less shocked than I expected, but still shocked (I learned later that he knew beforehand, but decided not to tell anybody anything). So came the most rediculous request of all:
To put down, within 1 A4 sheet, and in simple instructions, the things one had to do in order to fulfil the duties of the computer guy.
I. SHIT. YOU. NOT.
My answer:
"What I can do is write: 'Please read the following:', followed by the list of books one must read in order to get some introductory understanding of network and server management, with most accompanying skills."
I was so glad I got out of that hellhole.

Eureka! The IBM 5150 is on the internet!

I would like to tell you a UDP joke, but you might not get it..

Experience that made me feel like a dev badass?

Users requested the ability to 'send' information from one application to another. Couple of our senior devs started out saying it would be impossible (there is no way to pass objects across a machine's memory boundary), then entertained the idea of utilizing the various messaging frameworks such as Microsoft's ServiceBus and RabbitMQ, but came up with a plan to use 2 WebAPI services (one messenger, one receiver) along with a homegrown messaging API (the clients would 'poll' the services looking for message) because ServiceBus, RabbitMQ, etc might not be able to scale to our needs. Their initial estimates were about 6 months development for the two services, hardware requirement for two servers, MSSQL server licenses, and padded an additional 6 months for client modifications. Very...very proud of their detailed planning.

I thought ...hmmm...I've done memory maps and created simple TCP/IP hosts that could send messages back and forth between other apps (non-UI), WPF couldn't be that much different.

In an afternoon, I came up with this (see attached), and showed the boss. Guess which solution we're going with.

The two devs are still kinda pissed at me. One still likes say as I walk in the room "our hero returns"....frack him.

UDP vs TCP

*desolders Ethernet, USB and GPIO rails from Raspberry Pi to decrease height*
(Desoldering that shit from a Pi fucking sucks btw, no idea what solder or pads they use but it's garbage)
*boots up Raspbian to see whether it still works and to set things up*
...
Oh shit.. I need keyboard and mouse for this :') fuck me I guess... Long live planning ahead. Does there exist a KVM over TCP/IP yet? 😅

IP in a bottle :D

First lecture of computer networks. Let's shove all of these abbreviations with their meaning, and possibly a associated port number in one 1.5 hour lecture:

HTTP, HTTPS, FTP, FTPS, SFTP, TCP, IP, UDP, ISP, DSL, DNS, LAN, WLAN, WDM, P2P, TELNET, PGP, TLS, SSL, SSH, MIME, SMTP, POP3, IMAP, IANA, DHT, RTT, DHCP

I really feel sorry for students who didn't have previous knowledge about this stuff..

It has been bugging the shit out of me lately... the sheer number of shit-tier "programmers" that have been climbing out of the woodwork the last few years.

I'm not trying to come across as elitist or "holier than thou", but it's getting ridiculous and annoying. Even on here, you have people who "only do frontend development" or some other lame ass shit-stain of an excuse.

When I first started learning programming (PHP was my first language), it wasn't because I wanted to be a programmer. I used to be a member (my account is still there, in fact) of "HackThisSite", back when I was about 12 years old. After hanging out long enough, I got the hint that the best hackers are, in essence, programmers.

Want to learn how to do SQL injection? Learn SQL - write a program that uses an SQL database, and ask yourself how you would exploit your own software.

Want to reverse engineer the network protocol of some proprietary software? Learn TCP/IP - write a TCP/IP packet filter.

Back then, a programmer and a hacker were very much one in the same. Nowadays, some kid can download Python, write a "hello, world" program and they're halfway to freelancing or whatever.

It's rare to find a programmer - a REAL programmer, one who knows how the systems he develops for better than the back of his hand.

These days, I find people want the instant gratification that these simpler languages provide. You don't need to understand how virtual memory works, hell many people don't even really understand C/C++ pointers - and that's BASIC SHIT right there.

Put another way, would you want to take your car to a brake mechanic that doesn't understand how brakes work? I sure as hell wouldn't.

Watching these "programmers" out there who don't have a fucking clue how the code they write does what it does, is like watching a grown man walk around with a kid's toolbox full or plastic toys calling himself a mechanic. (I like cars, ok?!)

*sigh*

Python, AngularJS, Bootstrap, etc. They're all tools and they have their merits. But god fucking dammit, they're not the ONLY damn tools that matter. Stop making excuses *not* to learn something, Mr."IOnlyDoFrontEnd".

Coding ain't Lego's, fuckers.

My tablet is lying on a table 2m away from me and I have to install a new app.. but I don't want to get out of my couch ffs! And I haven't configured dropbear in it yet, and neither do I have adb over TCP/IP. Well fuck it then. My desktop with BlueStacks.. hah, it's running fucking WanBLowS. No remote access there. Too much to ask of that certified pile of crap.

But the point is.. moar remotes, moar better 😋 anything to not have to stand up, taught by my ability to log into a server in Italy from the comfort of my couch. SSH and the sysadmin trade sure is nothing short of amazing ♥️

I wonder whether this is a bug in Chrome, or if it's just Google drawing the conclusion from my northern geo-position, that we still haven't left the stage of building longships, raiding England and Scotland, burning monasteries and writing awesome poetry and literature in weird characters sets.

Well, I'm not Ragnarr f*cking Loðbrók or Egill Skallagrímsson, so I can't read electronic component data sheets the way those guys did.

I'll go grab my chisel, so I can carve a bug report into a suitably flat stone and shove it down the TCP/IP series of tubes leading to Google.

TCP / IP = ?

Was forced to do some work on Windows this week (CAD tools that runs only on Windows). I spent a few days just setting up the tools. There were quite a few things I realized I forgot about Windows (as compared to Linux).

1) Installation times are down right horrific. What exactly are the installer doing for 10 minutes?
2) .NET is a cluster fuck. Not even Microsofts repair tool can fix it, but rather just hangs. I ended up using another tool to nuke it and reinstall.
3) Windows binary installs are insanely huge, thus, takes forever to download.
4) The registry is a pointless database that must have been written in hell with the single intent of destroying users will to live. The sole existence of the registry is another proof that completely incompetent engineers designed Windows.
5) Rebooting is the only way to solve many problems. This is another sure sign of a fundamentally fucked up OS design.
6) What the heck is wrong with the GUIs designers? The control panel must be the worst design ever. There are so many levels to get to a particular setting I'm getting dizzy. Nothing gets better by the illogical organisation.
7) Windows networking. A perversion of the tcp/ip stack that makes it virtually impossible to understand a damn thing about the current network configuration. There are at least 3 different places that effects the settings.
8) Windows command prompt. Why did they even bother to leave it in? The interpreter is as intelligent as retarded donut. You can't do anything with it, except typing "exit" and Google for another solution.
8) Updates. Why does it takes hundreds of updates per month to keep that thing safe?
9) Despite all updates that is flying out of Redmond like confetti, it is still necessary to install antivirus to keep the damn thing safe. That cost extra money, and further cost you by degrading performance of your hardware.
10) Window performance. Software runs like it was swimming in molasses. The final stab in the back on your hardware investment, and pretty much sends performance on your hardware back a few hundred bucks more.
11) Closed source is evil. If something crash consistently, you might find a forum that address the issues you have. Otherwise you're out of luck. On the other hand, it might be for the better. I imagine reading the code for Windows can lead to severe depression.

I'm lucky to be a Linux dev, and should probably not complain too much... But really, Windows, go get yourself hit by a truck and die. I won't miss you.

That's how it all started ..

As we're all going about our various Easter, Passover, et al., family celebrations, I have the perfect solution to help train your families to stop asking you for help with mundane computer stuff:
Every time someone asks you to do/fix something, give them a full talk about what is going on in their computer around that system.
Don't forget you can talk about lots of things too:
- concurrency
- TCP IP / socket networking
- multi-threaded programs vs. single threads
- RISC vs. CISC processors
- Why linux is better than Windows or Mac
- algorithms
- logarithmic runtime
- teach them how to convert between hex, binary, and base ten
Really pour it on too. Soon they'll either figure out that you are a highly-skilled individual who is not their personal geek squad, or they'll be too afraid of a big lecture to ask for help.
Works with my in-laws like a charm.

Network Security at it's best at my school.
So firstly our school has only one wifi AP in the whole building and you can only access Internet from there or their PCs which have just like the AP restricted internet with mc afee Webgateway even though they didn't even restrict shuting down computers remotely with shutdown -i.
The next stupid thing is cmd is disabled but powershell isn't and you can execute cmd commands with batch files.
But back to internet access: the proxy with Mcafee is permanently added in these PCs and you don't havs admin rights to change them.
Although this can be bypassed by basically everone because everyone knows one or two teacher accounts, its still restricted right.
So I thought I could try to get around. My first first few tries failed until I found out that they apparently have a mac adress wthitelist for their lan.
Then I just copied a mac adress of one of their ARM terminals pc and set up a raspberry pi with a mac change at startup.
Finally I got an Ip with normal DHCP and internet but port 80 was blocked in contrast to others like 443. So I set up an tcp openvpn server on port 443 elsewhere on a server to mimic ssl traffic.
Then I set up my raspberry pi to change mac, connect to this vpn at startup and provide a wifi ap with an own ip address range and internet over vpn.
As a little extra feature I also added a script for it to act as Spotify connect speaker.
So basically I now have a raspberry pi which I can plugin into power and Ethernet and an aux cable of the always-on-speakers in every room.
My own portable 10mbit/s unrestricted AP with spotify connect speaker.
Last but not least I learnt very many things about networks, vpns and so on while exploiting my schools security as a 16 year old.

All sysadmins, PLEASE! For the love of God just block port 21 in any direction from anywhere, going anywhere.. FTP needs to die.. The f**king protocol predates tcp/ip for God's sake! We need to stop project managers using it, it's a nightmare!!

It's been three weeks now that „SPRING“ is over and Nerdism won over our interior decorations. Neither wife nor friends and family noticed. But I do. Every morning. This time I made an impact to our decoration. This single time

Image relevant.

Tried getting puter to talk, puter no want to talk.
Me sad.
Me tell puter to stay put and listen at 4444.

External device doesn't do shit.
Me sad.

Read the docs. Nothing. Written like a 5 year old would.

Be angry, how do I put external device into tcp/ip mode? No one knows, the docs don't know.

I get frustrated and pull the USB cable out of it.
Mfw it starts spitting out requests to my server with no end in sight.

Mfw the requests all just repeat.
Mfw the docs tell me to acknowledge a request I have to respond with a content type of
"application/x-www-form-urlencoded"
How.

Not possible.
Mfw I decide to dissect a request to check it's accept header.

Mfw it says text/plain.
Great, no idea in what format the thing expects it.

Try writing out query string plainly.

It fucking works.

Why can't people just learn to write proper documentation.

CS Teacher today:
"Transport Layer provides Security and Encryption to the communication" (TCP/IP stack)

me: WTF? Encryption is provided on the *top* of the transport layer (aka Application) ( and below [Network Layer] there is IPsec)

Teacher: no, it's wrong.

me: so Wikipedia it's wrong, RFC 5246 is wrong, and you have right?

Teacher: Yes.

me: Ok. (aka fuck you!)

IoT device endpoint: public fixed IP, raw TCP socket, no auth at all

Samsung Smart TV becomes Samsung Dumb TV.

Welcome back dear readers, to the next installment of my Raspberry Pi / Pi Hole / MitM box adventure!

For those of you who are new to this story, I'm a long experience programmer who knows very little about his home network or networking in general and has constantly been going over his 250GB data plan because 'rona, and thus, wants answers to "where is the data going".

So, I got the Pi, codenamed Mini-Beowolf, positioned between the modem and router... worked some fuckin systemd.networkd magic (which was sort of easy... but was hard cause I'm new to it) and viola, this son of a bitch passes through the ethernet and doesn't even show up on the router. Fu-King Beastly, I love it.

Now to static IP all my devices so I fire up my trusty TP-Link admin portal. I should add here... I've visited this admin about a total of 10 minutes prior to this when I set this wifi router up and just let it do DHCP.

So I'm getting to know my admin portal... I've got most of my devices connected to reserved IPs... and I find this one fuckin device reporting as "localhost".

Now, I've got a MAMP install... but it hasn't been running. But still I thought for sure it was just MAMP run a bit amok.

But no... it was my fucking Samsung "Smart" TV. That piece of shit is, and apparently has been reporting its device name as, sure as shit, fucking "localhost"... PROBABLY FOR YEARS.

Now, IDK how that didn't cause me any major problems over the years, and I read quite a few forums about people who it did mess up their network. So I resolved to rename the Samsung TV device.

I found the spot in the network settings of the TV... I changed the name from the pick list of rooms in a house like "Living Room" and "Bed Room", then I tried entering my own device name. But no matter what I picked, or no matter how many times I restarted/reset that TV the network name is ALWAYS "localhost".

Even though somehow my network survived this long... I'm not standing for that shit.

My Samsung TV is now blocked COMPLETELY at the router level. (After I ran one last factory reset and update)

The kicker? That Pi I built has a Samsung SSD... so I'm blocking Samsung WITH FUCKING SAMSUNG.

Needless to say, these are likely among my last Samsung purchases.

Join me next time when I FINALLY try to turn Pi Hole on and then get a tcpdump (or some other lesser output from the tcp stream) going.

When some other team wants to blame us because they're getting a HTTP Status Code 0....

That's not even a valid status... IT MEANS YOU ABORTED THE REQUEST AND KILLED THE CONNECTION...

OH STILL OUR FAULT... WELL DO U KNOW ABOUT NETWORK ISSUES AND SERVER OVERLOADING WHEN U SPAM IT WITH TOO MANY REQUESTS?

OH YOU RETRIED? HOW DID YOU RETRY? BETTER NOT BE SPAMMING US WITH MORE REQUESTS...

EVER HEARD OF TCP/IP BACK OFF LOGIC....

!rant seems that my raspberry pi serial idea is a little bit complex at the moment and may take a more serious turn later, but I have studied and found DOS based TCP/IP software that will allow me to use my 5150 with actual Ethernet. There are a few 8bit ISA Ethernet cards that will work in the 5150 and separate executables that will configure DHCP, DNS, and even allow me to use a terminal emulator and SSH to connect to *nix based computers over lan! I'll keep you all posted!

Old Days

All good things come in small packages. Some TCP and some others IP.

PSA: If you do reverse proxying stuff, prefer unix domain sockets over localhost internet sockets, if it's on the same machine (and if it's forwarded over ssh too). You can even serve HTTP as a unix socket.

Unix domain sockets don't have the overhead of IP, so generally speaking, data will flow to your other process with much less overhead.

I've recently stopped being lazy at this, and it's worth it.

Setting up npm private registry and mirror is like setting up machine for handling ddos attack.

Last time I was tuning linux kernel tcp ip stack by adjusting default variable values was ages ago but if you see 100 open sockets in a matter of second after you try to install single frontend dependency you start questioning your life.

Some of my colleagues are dumb as fuck! I changed the text on a button and now they are not able to work with the program anymore! i wish i could implement "headnut over TCP/IP"... BAM, BAM!!!

I know it's been said in a comic before but..

The power to punch people over standard TCP/IP

I never thought staring at Bluetooth pcaps would make me miss staring at tcp/ip pcaps

Another 'fun' rant

Wrote a new server application and got the request from customer services to make it compatible with a slightly older DB version.

Today, CS asked me to install everything on the customer's test environment so I made a build and installed it there.

Wanted to run the service, no .Net framework 4.7.1 installed. Fine, download the installer ...

Start installing .Net framework 'unsupported OS'. Started looking into it. Customer is still running an old unsupported Windows Server 2008 ...

Asked some colleagues whether this was normal. Apparently, yes.

Seems CS isn't capable of telling customers to at least have a supported windows version when they want our software. As if security issues due to people here not understanding TCP/IP isn't enough, we now have security issues due to old, unsupported Windows versions.

Note to self: never trust anyone who says that 'security is the most important thing in our software enviornment'.

The beginning of the TCP/IP

Please God let someone finally implement TCP/IP over punchcard with mechanical routers.

Recent VM/Emulation Adventures:

The goal was to get TCP/IP and SSH running on whatever weird VM/emulated machine, and connect to the chatroom at chat.tcp.direct successfully.

Longhorn, somewhere late pre-reset: Crashes right after installer begins "Starting Windows", 0x7b from sum-match ISO. Fail.

TempleOS (well, Shrine, but y'know): Dear god. No. No, I am not writing SSH in HolyC myself *fuck that,* fail.

Slackware: oh ffs i gotta use fdisk to partition this damn thing? and it's not even the good fdisk? Oh, wait... it hangs. Fail.

WinME: shockingly, was *fairly* stable... until it hung up WASAPI and the hypervisor two frames into desktop rendering. Fail.

Mac OS 7: First-boot after install, immediate unknown trap. Just works, eh? Fail.

Amiga: After about 85 resets and 7 hours of constant fighting with WinUAE, I finally got TCP/IP working. (Required 10MB of total RAM and an FPU to connect.) Success!

Win98FE: just... PuTTY and done. Easy. (This was the warmup.) Success...

Other people's achievements so far:

- Minecraft using the new QEMU interface mod thing.
- Hacked smart fridge.
- iPhone, from custom initramfs.

So I was just thinking scenario wise how if I founded a military organization who’s aim was to depose an insane dictator from power while remaining undetected including from all his insane supporters how I would use Linux

After I took every source package offline and modified and source checked it and disabled the ability for it to use regular tcp ip for anything but tunneling

The reasoning ? I just installed one program and it downloaded 40 some extra packages that I have no idea what are doing

Linux is great but do we actually know what the software is doing ? Same as windows only you can’t compiler that from scratch

It’s either trust a bunch of random people or trust a bunch of random people part of an evil company

Not the best of choices

But oh how beautiful it would be after I had 500 people pick every last package apart with a reasonable deadline of 2 years entirely offline at frozen versions

Then we could fork all the projects
Or only implement very carefully source reviewed patches transported via offline medium To computers that are running vms to house and test all additional patches so if it blows up we just copy our raw frozen image back over it and either scrap or repair the change

As connecting to the internet in general is not an good idea for silent running

Is there a cloud service that does nothing but redirect incoming HTTP requests to your home server without the need to have a static IP or an open TCP port ? Sort of like proxy

I am working on an embedded system, a microcontroller-based design. The system has an Ethernet port. I am using NetX framework in the microcontroller firmware.
The DHCP Client is executed properly, an IP address is assigned correctly when connected to a router. I connect a laptop to the router using a LAN cable. Then TCP sockets behave the way they should, UDP broadcast behave the way they should. The only issue is, when I connect a Laptop over wireless to the same router UDP broadcast are received on application on Laptop, but data sent is not received on the embedded device.
Any idea why?

Platform:
Laptop is Windows
