What's a port scan?

That site didn't explain what a port scan is, or am I missing something?

What's a port scan?

Arrie, I am not talking down to you at all, this is genuine advise;

if you are going to use the internet you should educate yourself about the basic mechanics of the hazards involved.

That's why I'm asking, I can't protect myself if I don't know what to protect me from.

[Arriemoller]

Lets start with explaining what a port is.
I always thought that a port is those things that you plug your USB cable into, but I get the sense that I might be wrong.

[Arriemoller]

Ah, fuck it, there's always something with computers.
FUCK COMPUTERS!!

I'm going to bed.

I love this view. All those worthless shitcoins in red next to mighty Bitcoin!

Ah......

Are you saying that if some are green, then they are not worthless (at least not in the last 30D)?
 

...it's best we don't discuss them here anyway.

[jojo69]

FUCK COMPUTERS!!

I feel you man.

I do not come to it naturally.

The entire shields up portion of gibsons site is about protecting your ports.

I read this name mindrust a lot, can someone remind me who that was ??

JJG perhaps??

There once was a coiner, whose name was mindrust,
He posted in WO, and gained our trust.
But little did he know,
He would suffer a blow,
When he did the unthinkable, and sold all his stash!

Even r0ach would agree that this move was quite baffling,
It's Bitcoin 101, you just don't sell pre-Halving.
But his mind was all rusted,
It was Masterluc he trusted,
So he blindly followed his all-bearish rumbling!

He blames COVID-19 for his panic reaction,
"Armageddon is coming, I just had to take action."
Now his Bitcoins are sold,
He is turning to gold,
In a desperate attempt to get some satisfaction.

Many WO'ers advised him to buy back some corn,
But he just couldn't live with the thought of being wrong.
Now he hears of Bitcoin,
And gets a pain in his groin,
Because deep down he knows, that his chance is now gone!

I know that those limericks are shitty as hell,
And I know that Jimbo's shit, as everyone's, smell.
I just hope that they serve,
To help us all keep our nerve,
And never ever give in to the pressure to sell!

And if all of the above hasn't made you, mindrust,
Reconsider, and quickly get some corn in your stash,
It won't be r0aches or ants,
At the seat of your pants,
But the boot of a HoDLer kicking your stubborn fat ass!

What's a port scan?

HTTP port is 80

Email or SMTP is 25

https://www.webopedia.com/quick_ref/portnumbers.asp
https://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers

Theres a whole list but the main point would be as you are a viewer on the net not a web server or an email server so any port you use is specific time limited not open, why would traffic be coming to you without request so you dont want open ports like open doors.  You only open a port like you open the front door, hence the idea of shieldsup is check you are not leaving yourself open to be a server. 
   The biggest or most common danger where this occurs is people on the net via cable, it can be very poor security or at least used to be and strangers will scan your machine and retrieve files etc.   Shouldn't happen nowadays but thats the most frequent occurrence historically, nowadays they'll attack via phishing etc which is an attempt to convince you to grant them permission of some kind.   If you google iobit and use that software you shouldn't find its any trouble to it, not going to argue whose best but they arent the worst and it uninstalls when you ask which can be right after 1 free use.

ports can be an open door into your computer. its why you dont want them open except for very specific circumstances.

there are ~64k ports. some are dedicated to certian functions. others are chosen by the program.

for example the bitcoin wallet uses ports to find and communicate with other nodes.

Pro tip...
If you enjoy seeing an endless number of posts with your username mentioned,
simply announce in here that you sold all your coins.

Well that's fucking awesome

Remember when $10 pumps were big. Then, Gox times and 2014 ATH $100 pumps were huge. Now its $1k pumps that seem huge. Whats after next ATH? $10k pumps in one day? That would mean if you own 10 BTC and sell perfectly on top and buy on the lowest, you could make $100k a day in a perfect scenario  

Yes... I member that there were increases in the amounts of BTC price swings that ere a BIG deal..

I am pretty sure when I first started trading BTC and practicing my laddering, I had orders that were only $5 apart... The price was in the $200s and $300s, so yeah, each order was triggered by $5 movements in price, which actually was not even easy to reach, sometimes.

In any event, of course, the numbers get BIGGER with the increase in BTC price, and of course, we are likely to make much better decisions if we consider the significance of BTC price moves in terms of percentages rather than dollar amounts, even though when we are caught in any particular BTC price range it is usually easier to think in terms of dollar amounts rather than percentages.


Also, don't be selling all your BTC merely because BTC prices move a wee $10k in a day...!!!!! .... Contemplate a more reasonable plan!!!!!

So...in my dream I was in prison.  I was having a meeting with Torque, as the two baddest dudes in the joint it was important that we have an understanding.

This was after I beat two guards to unconsciousness while holding my breath against the knock-out gas they had flooded the chamber with when they saw me rip a length of handrail off its stanchions.  It was important to get off on a good foot and earn some respect.

Oh gawd!!!!!

Most home connections involve a router (with NAT/PAT) which by default blocks all incoming connections to all ports. So they're not concerned in what's reachable from the internet as much as what services you have running on your PC (the timing part is just a technique to identify open vs closed ports). Essentially, when you open goldman's site they can check if you're running a bitcoin node and if you do display a page of a middle finger rather than a log in page. Browsers should probably push an update ASAP to disallow websockets to local host by default.

I think all the bear trolling and attempts at scamming around Bitcoin is super weird. Go to any Precious Metals web forum and you never see bugs talking about TA charts, elliott waves, when to buy, when to sell, trying to call bottoms/tops, blah blah blah.

Interesting observation.

Gold bugs are more at the preserving wealth stage. Coiners largely at the earlier hustling-to-get-wealth stage.

The majority of the bugs I've seen on PM forums are self-admitted millennial age range, which blows a large hole in your statement.

Unless you mean crypto tarders... who are in the hustling-to-go-broke stage.
