I just started a job as a new dev at a small company. I was supposed to be one of two devs, but the other one quit the day after I was hired. Seriously? Yes, seriously.

@cl-netbox if i would know whats causing that i would shut it down

I knew which Angie you meant.

fritzbox 6360 cable

jokerdino

@ByteCommander is that the affectionate way to call her?

Byte Commander

@Videonauth I got a 6340 cable.

Videonauth

yeah but it has something to do with me yesterday installing ubuntu server

Byte Commander

@jokerdino Not really. That's the general nickname used everywhere, mostly in satire.

@Videonauth No, it hasn't. Mine is a normal 16.04 desktop.

And I also got the same amount of messages on every Ubuntu system with UFW here.

Videonauth

yeah but i hadnt that before and i not have this mess on my laptop

Byte Commander

6:23 PM

Probably you did not have UFW before?

Or configured differently?

Videonauth

yeah but wich port is getting blocked

i only have three open ports

80 443 and 21

Byte Commander

I have no manual rules, just installed gufw, enabled it and set the profile to Home.

i think i have the culprits

just now to find out how to set them not running on multicast

and my router seems just to answer

paste.ubuntu.com/16640158

hah i think i found it :D

@ByteCommander do a ifconfig -a if your network cards running in multicast mode

if yes

ifconfig <networkcard> -multicast

this silences it

here the line for my wlan card

ifconfig wlp6s2 -multicast

yeahhhhhhh ... silence in the logs :D

Byte Commander

6:36 PM

      UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

That means yes...

And what is this multicast good for?

Videonauth

for me not any longer

hopefully

Byte Commander

Actually I don't think I want to disable it after having a quick glance at Wikipedia. Sounds useful.

I guess I just ignore the UFW logs.

Videonauth

well for me it logs in 5 different logs the same crap

mean 4gb log just for from midnight till now

and its still going on :-s

@Rinzwind: Was it you who said you knew someone who only even used HTTPS and refused HTTP or was that someone else? Anyway, I have become like that now, I now have things set up to reject all HTTP traffic so my paranoia just went up a little. :P

Rinzwind

@ParanoidPanda yes and he got hacked :=D

Byte Commander

@ParanoidPanda Who is Arthur Dent?

@jokerdino and that! :=D

And dolphins liked the fish we gave them :P

Byte Commander

Well... Probably I really should.

But for now, the weekly Doctor Who episode will have to be enough.

user139252

Doctor Who!

user139252

@Rinzwind And you should be careful about those in your life, even if you think they play a very small role...

user139252

You could accidentally be the cause of every single one of somebody's deaths in each of their reincarnations

user139252

And they might start remembering you...

Rinzwind

6:54 PM

@ByteCommander sorry? what weekly doctor who? are you THAT behind? >:)

user139252

And then ask to be reincarnated as something nasty so that they can kill you :P

Byte Commander

@Rinzwind Yes. Blame EinsFestival, they stopped the two daily episodes and reduced it to one per week... :-/

user136984

@TheBrownOne: And they create a large statue of you killing a fly with your slipper... And a sort of room dedicated to your horrors... :P

jokerdino

how many seasons are there? I might get started on it some day.

user139252

I loved that one :P

user139252

6:56 PM

Doctor Who? Depends. Old series, 2005 reboot, or combined?

jokerdino

anything that is relevant

wait, how old is the old series?

user139252

It started back in the 60's.

jokerdino

Nope.

user139252

William Hartnell was the very first doctor, and a darn good one at that.

Byte Commander

There are the episodes with Matt Smith currently on TV in Germany... Doctor number how many is that?

Seth

6:59 PM

11

user139252

spoiler alert: (12 if you count the War Doctor)

Byte Commander

The first episode I saw was "The 11th hour", which is doctor who 2005, season 5, episode 1.

That was the first one they broadcast on EinsFestival a few months ago.

And last Wednesday, they showed "The girl who waited", season 6, episode 10.

user139252

That one was lame.

Byte Commander

I've seen all episodes in between, but not more yet...

user139252

They made it sound like it was going to be such a great, moving episode

user139252

7:06 PM

And it was just "eh"

Byte Commander

Yes, it was kind of strange...

Mateo

That latest one was a good episode, with him in the time prison thing

Seth

@TheBrownOne eh, true.

Byte Commander

"The time of angels" / "Flesh and stone" were really exciting, I think. Those were the episodes with the weeping angels.

Seth

weeping angels are always fun.

Byte Commander

7:10 PM

:D

Seth

not that I have seen too many full episodes.

user139252

I've seen every televised episode.

user139252

Including the original series.

Mateo

Well David tennent cheated and got two regenerations - remember his hand?

Byte Commander

xD They sell soft rubber figures in the shape of weeping angels as stress reducing toys!

amazon.de/Doctor-Who-Weeping-Angel-Stressspielzeug/dp/…

user139252

7:12 PM

@Mateo That wasn't a full regeneration, though, right?

user139252

Otherwise, with War Doctor, 11 shouldn't have existed

Mateo

technicality, don't remember how it was explained

Seth

iirc it was done within 24 hours of his regeneration or something so it was a writeoff..

Byte Commander

I have seen far too few episodes yet to follow this discussion entirely... :/

user139252

@Seth But Captain Jack lugged the thing around for a while...

user139252

7:15 PM

Eh, I'm sure they explained it somehow

user139252

@ByteCommander Even Better:

user139252

amazon.com/Doctor-Who-Adipose-Stress-Toy/dp/B003X2W2US

Seth

So. I need to travel some 230 miles. Greyhound bus or Amtrak?

user139252

Greyhound is usually more affordable

Seth

There's a $12 difference right now.

Byte Commander

7:18 PM

@TheBrownOne Okay, and what is an Adipose?

jokerdino

sounds like fat

I remember a adipose tissue being yelled in my bio class

Seth

they are some kind of fat based aliens, yes.

user139252

They were super cute baby aliens made out of fat.

Byte Commander

Ah, found some info: tardis.wikia.com/wiki/Adipose

They can turn human bodies into living blobs of fat... :-|

user139252

But... they're cute.

Byte Commander

7:26 PM

Has anybody of you ever designed an own proper scripting language btw?

Terrance

@Seth Amtrak might be more comfy though. Greyhound is cheaper, but the buses get full, and no sleeping on them.

user139252

Guys, I love having a job again. Guess what I just found in the kitchen here.

user139252

Jolly Rancher

Jolly Rancher is a brand of sweet, somewhat tangy or sour/sweet hard candy, gummies, fruit chews, jelly beans, lollipops, gelatin desserts, gum and sodas. It is currently owned by The Hershey Company. The product was originally produced by the Jolly Rancher Company, founded in 1949 by Bill Harmsen of Golden, Colorado. The Jolly Rancher Company made ice cream, chocolate and candy sold at several "Ranch Maid Ice Cream" stores in the Denver area. The name was meant to suggest a hospitable, western company. == AcquisitionsEdit == Jolly Rancher was sold to Beatrice Foods in 1966 and to Leaf Brands in...

Seth

@Terrance well in this case I can get Amtrak tickets for ~$12 more than the bus.

greyhound has apparently gotten new buses recently though, whereas I'm sure the rail cars are still pretty old.

Rinzwind

@jokerdino you can start with the new series that began in 2005.

The 1st season of the reboot is must-see. it has so much things in it that become relevant later ;-)

Terrance

@Seth Might be better for the extra $12

Byte Commander

@Rinzwind That's from when Matt Smith becomes the new Doctor and meets Amy Pond until when?

That's where I started as well.

Rinzwind

@ByteCommander no from ehm.

christopher ecclestone

smith = 2010 through 2013

Byte Commander

7:38 PM

Ugh, right. That's season 5 of the reboot?

user139252

Aye.

Byte Commander

Sigh...

Can't they have one simple numbering scheme...

user139252

Don't you have Netflix? Hulu?

Byte Commander

Me? Nope.

user139252

It is a simple numbering scheme...

user139252

7:39 PM

Doctor #9 is season 1 of reboot

user139252

Doctor #10 is seasons 2-4 of reboot

user139252

Doctor #11 is seasons 5-....9?

user139252

Doctor 12 is current.

Rinzwind

they have :=D
it is messy enough with all the time warping not need for weird numbering schemes

Byte Commander

:D

Seth

7:40 PM

@TheBrownOne 5-7

8 & 9 are 12th doctor.

Rinzwind

it is not The Disappearance of Haruhi Suzumiya :+D

user139252

@Seth I forgot which season we were coming up on :P

user139252

I thought for some reason we were coming onto season 12

Rinzwind

season 10 is next year With Bill the companion

user139252

I thought 4 seasons was too long for Smith...

Rinzwind

7:41 PM

I will miss Clara :P

user139252

Me too. I always loved her style.

Rinzwind

@TheBrownOne sorry but seasons here was SIX episodes a year. far too few.

Byte Commander

This site seems to be helpful to learn about all seasons and episodes of the 2005 reboot: tv.com/shows/doctor-who-2005

user139252

@Rinzwind I wasn't the hugest fan of Smith as the Doctor. Don't get me wrong, I loved the Ponds, but 11 wasn't my favorite.

user139252

12 is so far my favorite, for some reason.

user139252

7:43 PM

Then 10, 11, 9. Mainly because we didn't get much time with 9, I couldn't grow attached.

user139252

(of the reboot series, anyway. Everybody's favorite is obviously Baker.)

Byte Commander

I only got to see Smith yet...

Rinzwind

The Disappearance of Haruhi Suzumiya was funny. doubt anyone here saw it. it too is about someone able to warp through time but the broadcasted in the normal time flow. so the series got really messy cuz you'd get something told that happend in the future :D

and they then later put in on TV in the order the series flowed (so not following the release) and it all made sense :D

Seth

from the little I've seen it's something like: 12, 11, 9, 10.

but I like them all.

user139252

What?! 10 is last?!

Seth

7:44 PM

yeah.

user139252

But 10 had Donna, and that dynamic was amazing!

Seth

maybe that would change if I watched more... possibly.

user139252

Plus, I mean, David Tennant...

Seth

like I said, I like them all though. It's hard to even make a list :p

Rinzwind

I loved all the new doctor who's :) Tennant and Smith are both good.
Ecclestone had to play a dark doctor. did not care for it when it was broadcasted but it became crucial for the later doctors.

Capaldi did not do a lot yet. But he made a good impression the 1st episodes

user139252

7:46 PM

Yeah, I'm really liking Capaldi. I'm so glad he finally got his screw driver.

user139252

Those sonic specs were bugging me.

Rinzwind

BUT I do rank DW above star trek and other series.

it was the 1st series I watched as kid. The showed DW here in the 70s

Seth

I absolutely love Capaldi's portrayal of the doctor.

Videonauth

@ByteCommandersudo ufw deny from 192.168.0.1 to 224.0.0.1 just replace the src to match your src adress in your logs

see the comments on this answer

A: How can I disable UFW logging for a specific event?

Base on this answer from ServerFault, ufw supports per rule logging. By default, no logging is performed when a packet matches a rule. All you have to do is create a UFW deny rule to match those multicast packets.

Henry WH Hack

I miss @Serg.

Videonauth

me too

but i hope he enjoys his time off

yay ... silence is golden golden sings

the UFW spam stopped

Byte Commander

@Videonauth For whatever reason, I did not receive that as ping. Probably because you omitted the space before sudo.

Videonauth

aww :)

well i have log silence now

Byte Commander

8:19 PM

But for what price?

Videonauth

just denying multicast pass throughs

Byte Commander

I'm still not sure if I profit from this multicast or not.

Videonauth

dunno i have nothing multicast using

in worst case you can disable that rule

i simply set ufw to deny from 192.168.0.1 which is my router to 224.0.0.1

Byte Commander

My /var/log is 13MB in total, I don't think I need to take any action.

Videonauth

well for me it was worse

i deleted at 18:00 arund 4 GB only from today and now i again deleted nearly 1,5 GB

because ufw was posting these in multiple logs at the same time

Henry WH Hack

8:22 PM

@Videonauth WOW!

Don't you think that in this case something else might be really badly configured ?

Videonauth

But I will if I have to.

user139252

Did you figure out the root cause, though?

Videonauth

8:54 PM

the router works on partly ipv6 settings and multicast boradcast mode

and since i have no firmware access to the router myself i cant change it but i can at least silence up UFW

user139252

Ah, alrighty.

user139252

Glad you worked it out!

Videonauth

yeah i have on my OS hdd only 120 GB and alone today i deleted 5,5 gb of logfiles only from one day

and up to that it made it almos impossible to fix other issues that still are here on that system because the logs where clogged with those entrys

ah btw since youre here where did you get your x509 certificate and how much did it cost ?

or is it supplied by AWS ?
