lol reminds me of the pastarino

bob

hello need help!!

Dave

called 911, helps on the way

bob

tut tuut tuutt

I'm setting up arch linux but have problem with ethernet access, is anyone good with that here?

Dave

most of us are good at everything in here.. for instance @qasdfdsaq recently wrote a ipv6 dns server in python that takes shell code and pieces it up as ipv6 addresses, with a client that asks for a bunch of domains and recieves the addresses, maps everything to executable memory, copies them over and executes..

qasdfdsaq

wat

Dave

23:18

YOU DID!!!

qasdfdsaq

I must have done it in my sleep

Dave

;]

bob

welp could you help me then @qasdfdsaq ?

qasdfdsaq

I don't even understand myself

Who am I? Why am I here?

bob

oh okay

qasdfdsaq

23:19

What is teh meaning of this?

Why is there a strange man in my bed?

Dave

bob, @allquixotic recently wrote a similar app that he named 'synstant messenger' that's an entire application that does nothing but send text messages to clients via different dest ports using syn packets.. (theres no actual handshake) ITS PRETTY BRILLIANT.

NO TCP SESSION REQUIRED

bob

idk how that is relevant to my problem

Dave

They're the smart ones here, not I

bob

I'm simply trying to access the internet using ethernet in my vm

oh okok

Dave

I only dream of being like them.

that is above and beyond my knowledge of tcp/ip

one of these days ill learn how to properly set up nat within my VM's and ill be able to resolve your issue when i experience it.

until that day comes... i just wont have a clue! :(

Bob

23:26

meh

inefficient and likely to be detected as SYN-flooding

Dave

@bob: true.. ;)

qasdfdsaq

That's what makes it so much better than sex.

Dave

@bob: but if 2 people are wanting to have a private conversation using it then that type of protection likely wouldnt be turned on both ends.

right? :)

bob

bob can you help for such thing?

Dave

it would let off some noise.. but at least it would be private.. and you could even implement a layer of encryption randomizing ports using an algorythm.

gl sniffing that.

Bob

23:30

@Dave ...that's not encryption

that has nothing to do with encryption

that's also not secure at all

if you want encryption, then use encryption

use a standardised protocol. that's TLS 1.2 these days, with AES-GCM preferred.

do not roll your own.

Dave

im not referring to TLS though.

Bob

if you DIY encryption, you fail

Dave

or SSL

No data within the packets.. just syn packets and ports.

A = port 23 B = port 24 C = port 25.. etc.. (non reserved iana ports though obv)

bob

@Bob can you help me with configuring ethernet on arch linux?

Dave

what seems to be the issue with configuring ethernet interface on arch linux

is the network interface not there?

bob

23:43

I got the interface right from ip link : enp0s3 then I replaced the interface in the netctl/eternet-dhcp saved
then I tried to run sudo netctl start eternet-dhcp but it got an error:
A dependancy job for dhcp.service failed. See journal ctl for more info

Dave

:( i hate systemd

just saying that in advance.

what does the log say?

bob

what do you mean

Dave

'see journal ctl' for more details

bob

idk where its located xD

Dave

sounds like you're missing something that is a prerequisite of that command thats missing. (ie dependency)

bob

23:45

I'm following a youtube guide

Basic Arch Linux Install for Beginners

►

Dave

type which dhclient in the shell

#which dhclient

should show /sbin/dhclient

or something

bob

no dhclient!

and no ifconfig btw

Dave

ifconfig = ip a

bob

you have some knowledge mr dave

Dave

Installation

netctl is part of the base group, so it should already be installed on your system. Otherwise install it as usual.

Optional dependencies are shown in the table below.

Feature Dependency netctl program
(if relevant)
Automatic wireless connections wpa_actiond netctl-auto
Automatic wired connections ifplugd netctl-ifplugd
WPA wpa_supplicant
DHCP dhcpcd or dhclient
Wifi menus dialog
PPPoE ppp

bob

23:48

and yes I typed that and yes I have interfaces

Dave

you need to install dhclient

bob

without internet?

Dave

likely*

oh damn

bob

or wait, that means I have it already right?

Dave

Journeyman geek to the rescueeeeee

Journeyman Geek

23:50

journalctl is a command

its basically a program to view the log. Which of course, should be in plain text

Dave

you'll likely see soemthing like 'missing dhclient'

in the logs

'/sbin/dhclient' command not found

bob

how do I run it?

nvmm

Journeyman Geek

I have no idea about arch

buuuut

Dave

with your fingers

Journeyman Geek

ifconfig is outdated

Dave

23:51

ifconfig has been outdated for a very long time!! and replaced by ip a

Journeyman Geek

ip is the command and the equivilent of ifconfig is ip addr

Dave

which is the same exact thing as what i just said! :)

just shorthand form

Journeyman Geek

Also, you can tell how up to date someone's linux skills are from that ;p

bob

the logs says so much but so little

Dave

Journeyman Geek has written many o'reilly books related to arch linux installs.

bob

23:53

dependancy failed for my ethernet-dhcp

Dave

I have 3 copies of them sitting on my desk

Journeyman Geek

@Dave nope

Dave

@bob: dont listen to @JourneymanGeek he's lying!

Journeyman Geek

I've done exactly zero arch installs

Dave

He has written many books

Then I guess this author listed on my book is not you then.. Darn

Journeyman Geek

23:55

That said, arch has rediculously good docs.

Dave

It says @JourneymanGeek though, oh wait.. im just getting old.. my eyes are beginning to give out.

Also if you ever build your own linux bootable usb distro, DO NOT USE SYSTEMD... It's soo slow. (I know from experience)

bob

I don't understand, I followed every step on the guide...
