It just kills me that ICMP redirects are such a blatant security hazard. They could have been so useful for simple, platform-independent, lossless service cutovers, but they also represent a low-effort avenue to a high-value target, enabling mitm attacks. I hate that we have the right answer right there and it’s even fucking standardized but no one can use it because of the Big Glaring Problem

Subnet Sunday: ICMP - The Voice of the Internet

📢🌐📡 Did you know that the internet has its own way of talking? It’s called ICMP, also known as the “Voice of the Internet.” ICMP, or Internet Control Message Protocol, is a crucial communication protocol that helps keep the internet running smoothly. In this Subnet Sunday post, we’ll unravel the mysteries of ICMP, explain how it works, and why it’s essential for the functioning of our…

Pinging and Tapping

In the world of the Murderbot Diaries, communication is often conducted via comm and feed. Generally, comm is used when internal network is not available, or when one is trying to communicate across space, and feed is used when people are on the same network and allow each other access.

We also often see “pings” and “taps” as a way of quick communication.

Generally, pings are used for comm communications, and taps are used for feed communications, but there seem to be different purposes. Here are what we can gather from the story, and also from real life examples.

[Pings]

Purpose in the MB world:

Pings are typically used for signalling, checking connectivity, and getting responses from other systems or units. They act like a way to see if the other side is present and ready to communicate or respond.

Purpose in Real Life:

Network Connectivity: In computer networks, a "ping" is a diagnostic tool used to test the reachability of a host on an Internet Protocol (IP) network. It measures the round-trip time for messages sent from the originating host to a destination computer.

Usage in the MB World:

Status Checks: Used to check if systems, such as satellites, drones, or transports, are active and responsive. For example, pinging a satellite to see if it responds​​.

Communication Initiation: Used to start communication with other systems, often to establish a connection or share data. For instance, pinging a transport to offer media files in exchange for a ride​​.

Detection: Used by systems to detect the presence of specific units, like SecUnits, without direct contact​​.

Usage in Real Life:

ICMP Echo Request/Reply: The ping command sends an ICMP (Internet Control Message Protocol) Echo Request message to the target host and waits for an ICMP Echo Reply.

Network Troubleshooting: Used to determine if a particular host is reachable and to measure the latency between the source and destination.

[Taps]

Purpose in the MB World:

Taps are used more for internal communication within the network or feed. They serve as a means to acknowledge, signal actions, or provide private communication without verbal interaction.

Purpose in Real Life:

Internal Communication: In many systems, "taps" or similar mechanisms are used to signal and communicate internally within a network or system.

Usage in the MB World:

Acknowledgments: Used to acknowledge received messages or instructions. For instance, tapping back an acknowledgment to confirm receipt of instructions​​.

Private Communication: Used to send private or secure messages within the feed, often to communicate specific commands or information discreetly. For example, tapping the feed to communicate privately with another character without others listening in​​.

Control Signals: Used to signal or control actions within the feed, like tapping to instruct a character to fall back or take specific actions​​.

Usage in Real Life:

Signalling Mechanisms: Within computer systems, taps can be analogous to various signalling mechanisms like inter-process communication (IPC), which includes methods such as semaphores, shared memory, and message queues.

Acknowledgments and Control Signals: In networking, control signals and acknowledgments are crucial for managing data flow and ensuring reliable communication. For example, TCP (Transmission Control Protocol) uses acknowledgments to confirm the receipt of data packets.

Network Taps: In the context of network security, a "network tap" is a device that allows access to data flowing across a network for monitoring and analysis.​​.

[Comparison]

In both the fictional world of Murderbot Diaries and real life, pings are primarily used for external signalling and connectivity checks, while taps are used for internal communication and control within the feed network

-------------------------------------------------

[Something Worth Noting]

There are some instances where taps seem more reasonable, but pings are used instead.

In Artificial Condition when Murderbot was watching Sanctuary Moon, and ART was trying to get its attention, asking to watch World Hoppers together. (see Artificial Condition, Pings, 5, 6 my AO3)

In Network Effect, when Murderbot finds that a hostile vessel (i.e. ART) was approaching and notifies the team quickly (see Network Effect, Pings, 1 my AO3)

In Network Effect, when Murderbot was locking itself up in the bathroom (see Network Effect, Pings, 11, 12 my AO3)

In Network Effect, when ART requested a private connection (see Network Effect, Pings, 13 my AO3)

In Network Effect, when Amena comes along with Murderbot to investigate Barish-Estranza shuttle, but is told to wait outside. She offers to help to which Murderbot pings acknowledgement (see Network Effect, Pings, 14 my AO3)

At the end of System Collapse when Murderbot pinged Three to ask if it wanted to listen to Holism explain planetary infrastructure (see System Collapse, Pings 15 my AO3)

Of these, 1, 3, 4 are where ART was sending pings to Murderbot. This is actually quite sweet, because we can tell that ART is being very polite to Murderbot. ART is fully capable of slamming into Murderbot’s private feed, but in all of these occasions, Murderbot has been rejecting feed communication which it reserves for friends and clients. ART is respecting this.

Instance 2 is unusual, and I am not 100% sure why Murderbot chose to use ping here. But since it was emergency, and ping is a protocol where it receives automatic response if it had been received at the other end, it was sufficient for its purposes.

When we read the context in which 5 happens we notice that Murderbot is now inside the B-E shuttle, and for security reasons, ART had cut it off from the feed network. So, Murderbot has the options of either verbally answering to Amena, or sending a ping for acknowledgement, and it chose the latter.

In instance 6, Murderbot seems to be being polite to Three who is busy (?) watching educational media. They are cordial to each other, but because Three is still not used to being a free SecUnit, Murderbot is being more careful around it.

--------------

If you are willing to be bored to death, you can see my AO3 post for the list of all the instances where pinging and tapping happen!

ICMP, short for Internet Control Message Protocol, is utilized by network devices like routers to communicate error messages and operational status regarding the network's conditions. Network devices typically generate ICMP messages in response to errors, such as when a packet cannot be delivered to its destination or when a router needs to communicate that it is experiencing congestion.

Here is the masterpost for round one of the zaynsalbumsficfest. We are happy to announce that we will be back later this year with round 2!

Thank you to all the wonderful writers who have joined our fest, we are so happy that so many of you were able to celebrate Zayn's music with us!

Fics and summaries under the cut.

⋆ and right from the start by @so-why-let-your-voice-be-tamed

It all started when Zayn ran into Aiden again.

Aiden. Liam hadn’t thought about him in years, if he’s honest. They’d been in highschool together, but that was ages ago, and they’d lost touch, as people do when you go to uni. Last thing Liam heard was that he’d gone off to London to study at ICMP. Liam and Zayn had stayed up North, going to Manchester together.

They’d done everything together, from the moment their mums had introduced them to one another. Liam had been the new neighbour, moving up from Wolverhampton, and Zayn had been all of three years old when he’d declared Liam his best friend. Liam had looked into those hazel eyes, framed by impossibly long eyelashes even then, and felt like he’d come home.

Even now, in their twenties, they still do everything together. They’d finished their degrees at the same time – Zayn the responsible one, making Liam study even when he didn’t feel like it – and had moved down to London together, finding a flat and jobs and building up a social circle that consisted of both Zayn and Liam’s friends.

It’s nice. It’s comfortable. And somehow Liam hadn’t expected it to end.

zayn and louis are exes. they still sleep together.

⋆ catching eyes across the room by @beardyboyzx

Zayn is nineteen when he gets his gift.

People say that when you get your gift, you can hear the Magic’s voice whisper what it will be to you the morning of your birthday: Zayn has always wondered what Magic sounded like — but most importantly: what will It say to him?

⋆ sipping pink lucozade by @zaynmaliksmiddlefinger

If Zayn had to describe his life for the past few years, “struggling musician” would be a massive understatement. The last thing he needs right now is a distraction from his last shot at a successful career.

Enter the most tempting distraction he could imagine in the form of Liam Payne, the irresistible—and deeply closeted—playboy and son of the owner of Zayn's label.

Liam Payne is used to getting everything he wants with a tap of his black card—but he isn’t used to wanting something money can’t buy.

Let alone something he shouldn't desire to begin with.

Both men know they shouldn't risk everything by giving in to temptation, but it just might be too late.

⋆ love me tonight by @1ds5directions

When they meet for the first time, Zayn is on set of a new music video for singer Liam Payne. Louis didn't tell him about the cross he did at the intimicy work agreement when filling out the papers for Zayn. So a (surprise) scene of clothed grinding turns into two orgasms later in Liam's changing room. The second time they meet is a coincidence but the third and fourth time are not.

⋆ my sleep was stolen, I'm searching for thieves by @yeahexactlyimnotreal

A lack of sleep leads to a chance of reconnection, with a whole lot of history written in dreams.

A series of hopes, dreams, and memories of Zayn as he rediscovers the most important people in his life.

⋆ like a sour diesel, she burns by @larry-hiatus

He’s just an exotic dancer—one whom Zayn enjoys more than the other girls at the club; one with whom he happens to share a complicated past; one who lets him blur the lines between what’s right and what’s wrong. All of that may be true, but Harry is still just a stripper to Zayn, and nothing more. Really.

⋆ can you feel where the wind is by @fallinglikethis

It had been a normal day, just like any other. He’d been doing a PR tour for his father’s election campaign, making appearances in marginalized communities to let them know that his father saw them, would work for them if elected. He’d always maintained that his father would make a bigger impact by showing up himself, proving that he meant to keep his promises and was not just sending his son to give lip service. Liam’s advice had fallen on deaf ears, but then it’s not like Liam had listened to his father’s advice either.

Liam still remembers the argument, still remembers the feelings of stubborn exasperation and eventual grudging acceptance, when his father had insisted that Liam needed a security detail while out doing his father’s bidding. He remembers arguing that he had no real power over anything, so no one would care about him, let alone try to hurt him. But that assessment had proven to be untrue today.

⋆ baby, i'm right here by @enchantedlandcoffee

“Yeah, but that wouldn’t stop us from dating, I’m way too irresistible for that,” Louis grinned, groaning when one of their throw pillows hit him in the face. “Knobhead.”

“Wanker,” Zayn retorted, sticking his tongue out at Louis. Louis stuck his out in retaliation, gently kicking at Zayn until the man grabbed his feet and held them still. They stayed there in silence for a while, Zayn reaching for the remote to turn the TV on as Louis focused on a weird patch of colour on their ceiling.

“Do you ever think that maybe we should date?” Louis asked, gaze staying firmly on the patch of colour even as Zayn turned to look at him.

Or

The one where Zayn and Louis are best friends and, after much prompting from their family members, try and give dating a go.

Louis hears "Good Years" for the first time. Harry is there to pick up the pieces.

Zayn makes some questionable choices. Louis makes some long awaited moves.

Sometimes heart broken all over again is the first step to healing and making everything right again.

⋆ i will die if i don't try by @lightwoodsmagic

It had started with an Instagram message this time.

Actually, it’d started with a comment, a simple ‘this sounds big already’ with clapping hands, one that Zayn had found easy to reply to with a casual ‘@liampayne appreciate it bro, thanks for the love’ and adding his own emoji. He’d sat and stared at his phone, watched as fans seemed to suddenly appear to like Zayn’s comment and show their excitement in capitals. He’d sat forward on his couch, leg bouncing as he’d chewed on his fingernail and waited for the message or call that was sure to come.

He’d been the one to reach out last time, after all.

It’d only taken Liam five minutes to send through a DM, something that surprised Zayn - he couldn’t remember ever speaking to Liam this way before.

Zaynie! How have you been? New song sounds sick.

And that’s all it had taken.

Or, Zayn and Liam used to be together in One Direction and they've been drawn back to each a handful of times over the last decade. This time though, with Zayn in Paris for Fashion Week, everything feels different.
