However port scanner says port 22 is open. How can I run a bitcoin node on port 22?

Or would having a vpn work?

Windows, because I've never tried other operating systems. I'm joking.  To be honest, I was got used to Windows since my childhood, when my father bought the a new computer. That was Pentium 100 on Windows 95. Since then, I prefer Windows. I was using Windows 95, 98, Millennium, XP, 8 and now I have Windows 10. I've tried Linux once, but it got me confused a bit, and that experience last only for a week. Personally, I really like Windows 10. On my old laptop, it works really fast.

The best choice for me is windows, why?
Windows gained most of the popularity. It is open source, hence it is flexible and you can do what ever can be done in computer with windows. Aside from it is easier to use, the is the most reliable operating system because you can use it easily and have it easily.

Windows 7 Pro. Too used to it as have been using it for some time.

It depends, for daily use I choose Ubuntu hands down since it is as easy as windows but without any viruses and backdoors, in the past I used to have windows just to run some apps and games but now I use wine and I run Ubuntu exclusively.

No experience with Ubuntu, but my first Microsoft OS was PC-DOS. I actually wrote an OS for an 8085 based system. My Linux experience goes back to SuSe over 20 years ago.

I've had enough experience with Windows to know that it's bloated and insecure, and the latest Windows 10 brought home to me the influence that globalists like Soros are having on our computing. As Bitcoiners, I would have thought that members would be aware of this.

I suspect it will be less work for me to optimise Ubuntu, than constantly having to check Windows to see what Microsoft has done in their latest ( and over-frequent) update. I don't want Cortana, One-drive or Defender. If you stop and think about it, if Microsoft wanted to stop viruses, they would build protection into the basic operating system. I'm amazed that they can still have buffer overrun vulnerabilities - I fixed those back in the 1970s when I was a systems programmer working on some multi-threaded real time systems.

I see you have Linux on there, but I think Tails should be added to that list. It has a built in Bitcoin wallet and it is the only OS I know of

that support Bitcoin.  We should support OS's that shows interest in supporting Bitcoin. It is much smaller than other OS's and a lot

more anonymous.  {Just make sure you download from a trusted source}

I work for an ERP based company project for banks.WE deal with charts,graphs,dashboards everyday.Pretty obvious
that we use such libraries on daily basis.We only use open source stuff and trust me,the options d3.js or velocity has to offer
can pretty much get you all you can get from a paid project.
However,it's a personal opinion.

Because it's a paid product!I don't support the entire idea of taking something which comes free of cost,modifiying it and selling it for way more than it should be.Open-Source does the same for way cheap and it takes brains obvious.Anyhow,OP found what was he looking for.

It's fairly simple.
I want to run a full node over public wifi on this cheap notebook.
I've removed windows 10 and replaced it with Ubuntu. As it's only got a small internal ssd, I've added an external 256Gb SSD, and I want to copy the blockchain from my other computer onto the external SSD a pain in the exit port, so I'm looking for an easy way to copy the blockchain without introducing Windows restrictiuons on the SSd. I might give up the transfer to the USB stick, and try using Bluetooth tomorrow. The problem with Bluetoth is that it will only transfer files and not directories.

Actually, I've just had another thought. I might use ftp to put it on a server, and pull it back from there.

winscp C:\path\to\bitcoin\blockchain user@hostname:/home/user/.bitcoin

scp /path/to/.bitcoin user@hostname:/home/user/.bitcoin

It isn't the Ubuntu that's the problem. It took about a minute to run the sudo to install the drivers. I'm not sure why they aren't in the basic installation, but they are easy to add, and they seem to work perfectly. Windows 10 is a different matter. It seems to be deliberately difficult if you want to communicate with a different world. I might dump it from the main computer when this one is stable.

Well this was going well, and I bought the Samsung SSD drive. It's preformatted for exfat, and I gather that is the best format for an external ssd. Ubuntu didn't like that, but a quick run of a sudo command soon fixed it, and now it likes the drive. Windows 10 is a different matter - it wants to reformat the drive. I gather that I may be able to get windows to recognise it if I reformat under Ubuntu, and set a partition flag (I forget which one). I'm inclined to forget the idea of using the drive to switch machines, and I'll just use it with the Linux book. Already I prefer the Ubuntu, and I haven't started to customise anything.

The plan now is to copy the blockchain onto a memory stick, and to copy that onto the SSD. Then I can install the Bitcoin core. I'll just check to see if I need to move anything else with the blockchain.

OpenBSD comes with a secure-by-default setup and it is lightweight. Though, if you did not already setup linux at the time when you had to partition your disk yourself and configure your network manually you might find it very painful to get started with OpenBSD (but there is excellent guidance out there [1, 2] and the effort pays out if you want a highly secure and stable platform!).

The setup/install has been simplified a lot since I started with version 2.6 sometimes 1999 but it is still not "insert disk and click OK three times to accept some defaults"

On the plus side:

• High quality man pages (Linux improved there in the last years, but so many man pages in Linux are still just useless and I have yet to find a bad one in OpenBSD).
• Most system components are audited and fixed by highly capable people in the OpenBSD team.
• Integrated firewall (pf) that I would argue is the best open source packet filter out there and compared to the huge mess that iptables ruleset are it is almost natural to read the rules.
• OpenBSD is the home of OpenSSH and comes with strong and robust crypto
• OpenBSD team is strictly commited to Open Source principles, they never accept borked license agreements, things that do not comply with their BSD license are kicked out.
  
• OpenBSD team boasts about "Only two remote holes in the default install, in a heck of a long time!". This is impressing compared to every other OS.

Personally I'd recommend OpenBSD for servers or workstations that need that extra bit of security and confidence meaning you are ready to go an extra mile (or two, sometimes three ) to get the job done and you value security and stability over performance and bleeding edge features. But then you can lean back and just let it hum along. The OS might look ancient because it lacks a lot of features, but then again everything that's in OpenBSD has been done right from the beginning.

I'd say OpenBSD is the most secure OS in the world. But like with the most secure car for example, you should not expect it to be the fastest or the most beautiful car. If you have an old pc or can launch a VM with 256MB RAM and 4G disk I'd recommend to give it a try. It's not just a different linux distro - it's BSD and it can be fun.

HTH

I've got Ubuntu running with everything working, including the WiFi.

I can't use a convential HDD because of the power requirements. If I added one, I'd be no better off than with the other notebook, that has got a 2Tb drive in it. I've got a 128Gb Sandisk stick, and I used that to do the installation. I was going to use that for the blockchain, but I think it's too small. and wouldn't give me any room for growth. I'm interested to see how I get on with the SSD, and how much power it will need.

The BSD family (OpenBSD, FreeBSD etc.) is missing from your list.

I prefer OpenBSD and Debian, I try to avoid Ubuntu and all Redhat based distros since Redhat decided to cripple openssl in them. Though the switch to systemd makes me enjoy more and more OpenBSD installations over Debian.

I've never used Mac and my last Windows WS was Win2000.

Thanks, but I'm not going to use 3rd party solutions for this project.

This is going quite well. I had a bit of a hiccup yesterday, as I couldn't download the Ubuntu software. This morning was a different world, and it downloaded in about 15 mins over public WiFi. I tried to install Ubuntu using Yumi, and that was a mistake, as I couldn't get it working, even after messing around with the BIOS. After resetting the BIOS, and rebuilding the USB stick with the standard pendrive installer, everything ran smoothly, and the machine is running well under Ubuntu with no trace of Windows or its spyware.

I'll probably buy the SSD drive later and play with that.
