I'm fourty-four and fat, setting up computers is for 20 somethings
December 05th, 2019
Just turned down a job because I refuse to set up computers for a job.
Crawling under desks is for 20-somethings who are physically able to do so.
I've gone through too many pairs of jeans that I've ruined doing that in
the past that I know this isn't a job for me. Next.

Three Months left for SolarScale.DE
November 30th, 2019
I'm letting this domain expire. I've had it for around 10 years. Just gotta
update my contact addresses on my registrar as I believe this domain name
always finds it back as the owner address. I'll contact my registration
agent soon.

Slashdot turned Anonymous Coward postings off
November 28th, 2019
And there is a story that I commented on.. it was in regard to a Go player
quitting becuase "AI cannot be defeated"
Well here is my Reply:
A human brain is about 20cm by 20cm by 15cm give or take 5 cm on each end.
It is said to consume around 35 Watts. Can a computer beat that? We know
a computer can beat a human mind at gaming...but how large is this computer
is it a super computer, a quantum computer or a single little SoC computer?
This is what's important nothing else matters. And.. we dream!
Dreaming.. because we cannot explain it, oughta rock the sockets off a computer.

OpenSMTPD has filters
November 23rd, 2019
Since a few days when I upgraded my mail server I've been trying out different
methods of spam control. I think it's a total success what I have so far.
Over night it caught 14 spams. That's amazing. I'll continue to play with
these settings perhaps I can cut spam 80-90%.

One week left to get Christmas shopping done
November 22nd, 2019
I do my christmas shopping in November. This is to take the stress off
DHL and other couriers like Hermes. It takes a bit of the christmas spirit
away but that's another cynical gripe another day.

Someone is spoofing and it isn't me!
November 18th, 2019
I'm a good boy when it comes to forging source IP addresses. I have been
getting these in my logs:
Nov 18 12:16:59 kite delphinusdnsd[90398]: request on descriptor 12 interface \
"5.9.87.75" from 45.144.2.100 (ttl=249, region=1) for "directedat.usa." \
type=ANY(255) class=1, edns0, answering "REFUSED" (43/32)
Nov 18 12:16:59 kite delphinusdnsd[90398]: UDP connection refused on \
descriptor 12 interface "5.9.87.75" from 45.144.2.100 (ttl=249, region=1) \
ratelimit policy dropping packet
For one it's an illegal DNS packet. But how do I know it's spoofed? The IP
TTL is 249, meaning at the farthest point from me the spoofer started at 255
TTL or (255 - 249 = 6 hops), 6 hops away. He's not coming from the USA, or
that IP because when I ping it, it reveals a TTL of 8 hops (64 - 56 = 8 hops).
kite$ ping -c 2 45.144.2.100
PING 45.144.2.100 (45.144.2.100): 56 data bytes
64 bytes from 45.144.2.100: icmp_seq=0 ttl=56 time=45.155 ms
64 bytes from 45.144.2.100: icmp_seq=1 ttl=56 time=42.906 ms
--- 45.144.2.100 ping statistics ---
2 packets transmitted, 2 packets received, 0.0% packet loss
round-trip min/avg/max/std-dev = 42.906/44.031/45.155/1.125 ms
kite$ dc
255 249 - p
6
64 56 - p
8
On top of that my regions indicate the source region is 1 which is ARIN. But
6 hops out is a little bit too close, I don't believe the USA starts within
6 hops from kite, it takes 4 hops alone to get to the border of this network
in frankfurt. So to the script kiddie who is using me as a reflection attack,
HOW YA FEEL! (smile, it's your 15 min of fame).
