After years of using VirtualBox I moved to VMWare Player and wow

I'm not a serious VM user by any means, all I use them for is testing Windows 10 updates with my customizations, I mess around with Linux here and there and if I'm feeling nostalgic I boot up Windows 2000 or XP. VirtualBox always did the job although it was buggy with anything that required 3D acceleration.

I never really looked at other solutions because Hyper V always seemed intimidating and VMWare wasn't free besides VMWare Player which could only run existing VMs but not create new ones. Atleast that's what I always thought until people here corrected me yesterday.

So I switched over to VMWare player and wow, while I haven't tested Linux yet Windows 2000 - Windows 10 run like a dream and 3D effects are fully working, no UI glitches nothing. Sure there are a few sound cracklings going on but I can live with that, thanks everyone here who corrected me on VMWare Player!

Honestly it runs so well I wonder if there's any catch... will VMWare mine bitcoins on my system? Will it spy on me, will it declare world-domination if I use it for too long?

I'm obviously just kidding about the last part :P

How much space left on your local HDD after fresh mynode install - 1TB HD

My machine is linux mint 19.x running virtualbox and nothing else installed. I am at blockheight 573369 running mynode version 0.2.09 and my local disk has 186GB of space left. My virtualbox VM folder inside my home directory has taken up 704GB of space?! I dont understand whats going on here. The bitcoin blockchain itself today is ~270GB. My fresh and minimal install of linux mint combined with this i would expect not to use anymore than ~350GB total for the entire VM but something seems off. I have tried to blow away and reinstall virtualbox/mynode and this keeps happening. Yes, I have turned off and deleted the snapshot function in linux mint as well. The only folder on the entire system that is using up so much space is the Virtualbox VMs folder inside my home directory. Any help would be appreciated!

Is it a virus?

So, basically, my anti-virus (norton) have been telling me that an attack called "miner.bitcoinminer activity 7" is coming from "\DEVICE\HARDDISCVOLUME3\PROGRAM FILES\VIRTUALBOX\VBOXHEADLESS.EXE". I have noticed that vbox have been using a lot more cpu power and ram memory than usual. What should I do? Do you think deleting vbox will solve this problem or is there another way? btw i get like one bitcoin miner warning from this source every ten seconds.

03-16 15:35 - 'Scam?' (self.Bitcoin) by /u/Prisoner279 removed from /r/Bitcoin within 113-123min

'''
So I was in my discord dms this morning and I got a message from "BitMex News" saying I had won the giveaway of .75 bitcoin and I figured "Oh hey a scam, Ill run it on my VirtualBox and see what it tries to do" so I went on the website ([Bitmatic.com]1 ) and with a burner email I created an account and used the promotional code they gave me and sure enough it actually gave me .75 bitcoin. But I wanted to know if [bitmatic.com]2 is just part of their scam.

Trezor Troubleshooting Guide

I've noticed some redundancy in some of the issues raised on this subreddit, thought I'd start a generic troubleshooting thread of what I've found useful. I'd appreciate any suggestions mods or other experts might have.

I - Prerequisite

  1. Read the FAQ
  2. Read the Users manual
  3. Read the Developers guide
  4. Search the Wiki
  5. Try the trezor Troubleshooter

II - Trezor connectivity / stuck spinning circle

  1. Try different cable / USB port / computer
  2. Try without crappy Antivirus software.
  3. Manually add the bootloader registry value just to be paranoid.
  4. Install WinUSB driver with Zadig.
  5. Try disabling browser extensions / ad-blockers.
  6. Try Chrome Guest Mode (easiest way to disable extensions)
  7. Try different browser (Chrome / Chromium / Firefox / Brave)
  8. Try WebUSB
  9. Try Android
  10. Try VirtualBox
  11. Try old-wallet.trezor.io
  12. Try beta-wallet.trezor.io
  13. Try beta-wallet.trezor.io/next

III - Updated FW, coins are gone

  1. Try Legacy Account section.
  2. Did you use the right seed?
  3. Did you use the right passphrase?
  4. Did you enter the recover seed words in the order the Trezor asked you to (hint: not first to last)?
  5. Did you verify that your recovery seed words are in the word list?
  6. Did you check all accounts (click add account) for transactions, or check all MEW ETH accounts (next page) as well?
  7. Did you check your transaction history (Legacy and Segwit) to see if anyone moved coins while you were dormant?
  8. Did you regularly do a dry-run recover to verify that you actually possess the recovery seed that the Trezor is operating with?
  9. Check to see if your brother-in-law found your seed and stole your coins.
  10. Check to see if the digital copy of your seed was hacked.

IV - Can't / Don't want to update FW.

  1. Try performing a dry-run to ensure you have the right seed.
  2. Say a prayer and hope you have the right passphrase.
  3. Use an old version of Electrum / MyCrypto / MEW to see if you can find TXN history.
  4. Use an old version of Electrum / MyCrypto / MEW to move most funds.
  5. Use an old version of trezorctl to move the other funds.
  6. Buy a second Trezor and update that.

V - I'm new to this, How should I backup my seed / passphrase.

  1. Make it simple, your kids / kin may be the ones doing the recovery.
  2. Make it secure in a lockbox or safe or something reasonable.
  3. Make it accessible in case there is market volatility.
  4. Make it resilient and redundant in case there is a fire / zombie apocalypse.
  5. Don't make it digital, hackers are smarter than you are.

VI - I forgot my PIN now I can't access my device

  1. Say a prayer and hope you have the right seed.
  2. Say a prayer and hope you have the right passphrase.
  3. Wipe your device then recover with the seed / passphrase to reset PIN.
  4. Don't forget again.

VII - I forgot my seed / passphrase, what now

  1. Nothing, you effectively put physical currency in an incinerator, no getting it back.
  2. Realize that you've learned a valuable lesson that will serve you well in the future.
  3. Advocate to others the importance of following section [V] above.

VIII - I want support for CrappyForkCoin and I want it now!

  1. Figure out what the fork_id is for CrappyForkCoin and write your own coin JSON file.
  2. Use your JSON file to compile your own CrappyForkCoin trezor FW.
  3. Flash your CrappyForkCoin trezor FW to your personal trezor.
  4. Use trezorctl to make CrappyForkCoin transactions.
  5. Read the wiki on how to add coins just to make sure.

Malware analysis of Sepsis ransomware

About me and topic

Hello! I am a beginner level malware analyst/reverse-engineer, senior software developer, certified forensic investigator. The reason for the appearance of this report is the lack of such an analysis of the ransomware called Sepsis at that time on the Internet. The main purpose of my research was not only find out what malware does but also HOW it commits malicious actions.

This is my ever first post in english. English is not my native language so I hope you understand me right.

Required skills


To understand this topic you should be familiar with assembly language and malware analysis tools. In general, I explain each step in detail so don't worry if you don't have much knowledge about reverse-engineering and malware analysis.

Introduction


Malware was first discovered on May 14, 2018 by MalwareHunterTeam. I downloaded the sample from Virusshare (also you can do it here, do it at your own risk!). Sample has the following hash values:

SHA1 518d5a0a8025147b9e29821bccdaf3b42c0d01db 

SHA256 3c7d9ecd35b21a2a8fac7cce4fdb3e11c1950d5a02a0c0b369f4082acf00bf9a 

The analysis was carried out on Virtualbox with Windows 7 Ultimate SP1 64-bit. The type of malware is a ransomware. Damage by executing can be seen on the screenshot.

All files are encrypted and [[[email protected]](mailto:[email protected])].SEPSIS have been added to their names. Windows VM crashed.

Static analysis

First of all, open the file in PPEE with FileInfo plugin.

As we see, 51 out of 68 antiviruses define a file as malicious. Let's move on to suspicious strings.

Look at the line -KEY- ... - END PUBLIC KEY- this is the public key that most likely encrypts data.

The line looks like an argument to cmd.exe:
admin.exe delete shadows /all /quiet & bcdedit.exe /set {default} recoveryenabled no & bcdedit.exe /set {default} bootstatuspolicy ignoreallfailures
admin.exe delete shadows /all /quiet - deletes all backups of the system to prevent the recovery of damaged files.
bcdedit.exe /set {default} recoveryenabled no - disables recovery mode.
bcdedit.exe /set {default} bootstatuspolicy ignoreallfailures - disables the appearance of the Windows Error Recovery screen.

Open the URL strings.

it can be understood that the user will be asked to bitcoins and give a link to how to do it. Open the Registry strings.

Pay attention to Software\Classes\mscfile\shell\open\command. The registry branch Software\Classes contains information about which programs are responsible for handling certain file types. That is, the malware most likely adds some commands that will be executed every time you open the .msc file. It is possible that malware affects the operation of the Winlogon process, which is responsible for logging in/out of the system.

PE headers are normal.

No more interesting PPEE shows. You should not hope to receive complete information using PPEE or other utilities, but for obtaining initial information and information about what a file is, this may be enough. Strings can be added specifically to confuse or recover dynamically or to be encrypted. Strings in the file can also be viewed using the famous strings program, but its more powerful counterpart is FLOSS from FireEye. It can show even obfuscated strings in a binary.

We launch it with a command with writing to a file since it has a very large output.
floss sepsis.bin > c:\floss_output.txt 

Open and browse the resulting file. We can see html file with such content.
 
Welcome to Sepsis Ransomware!
All your files have been encrypted!
All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the e-mail [email protected]
Write this ID in the title of your message 16E734E0
In case of no answer in 24 hours write us to theese e-mails:[email protected]
The price depends on how fast you write to us. You have to pay for decryption in Bitcoins. After payment we will send you the decryption tool that will decrypt all your files.
Free decryption as guarantee
    Before paying you can send us up to 5 files for free decryption. The total size of files must be less than 10Mb (non archived), and files should not contain valuable information. (databases,backups, large excel sheets, etc.)
How to obtain Bitcoins
Attention!
  • Do not rename encrypted files.
  • Do not try to decrypt your data using third party software, it may cause permanent data loss.
  • Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam.

It looks like a message that will be shown to the victim after encrypting the files. We also see the line SeDebugPrivilege, which means that malware may connects to other processes. The line eventvwr.exe, in resulting output - signals a possible attempt to raise privileges. We also see names similar to the list of folders:

Windows MSOCache Perflogs DVD Maker Internet Explorer Reference Assemblies Windows Defender Windows Mail Windows Media Player Windows NT Windows Sidebar Startup Temp Program Files Program Files (x86) 

They probably used as a blacklist when encrypting. Open the file in PEiD to find out if packers have been used.

DIE shows us that the program is written in C/C++, this will allow us to decompile it well with HexRays in IDA.

You can guess what malware does without starting it by examining the imported libraries and their functions. This may not always help, as the file can be packed, but in our case we are lucky.

Dynamic analysis

The logic of the work of Sepsis in pseudocode

1 if (elevated) 2 copy_to(C:\Windows\svchost.exe) 3 add_to_autorun() 4 exec(C:\Windows\svchost.exe) 5 sleep() 6 else 7 copy_to(%TEMP%\svchost.exe) 8 add_to_autorun() 9 if (!elevated) 10 run_as_elevated() 11 sleep() 12 if (run_first) 13 run_first = FALSE 14 else 15 exit() 16 encrypt_all_data() 17 if (elevated) 18 wipe_backups() 19 set_process_critical() 20 rename_all_files() 21 show_user_manual() 22 exit() 

As we can see, the malware checks whether it is launched with elevated privileges - lines 1, 9, 17. Checking with TokenInformation, after calling GetTokenInformation, with the TokenElevation parameter.

https://preview.redd.it/lhy7tbwv30u21.png?width=602&format=png&auto=webp&s=ec40bef338534b27baf2859ef9e0ea0ede15056f

The first launch on the victim's computer is assumed without elevated privileges so the malware copies itself to a temporary folder (line 7), under the name svchost.exe

https://preview.redd.it/1zclhzry30u21.png?width=493&format=png&auto=webp&s=d7ade4d559ff56847aef85336baab6b09679a579

https://preview.redd.it/vardmezz30u21.png?width=977&format=png&auto=webp&s=52428ed15fc23b13b218f7920c1486283f8432f9

and adds itself to autorun (line 8) by adding %TEMP%\svchost.exe to the HKCU\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Shell.

https://preview.redd.it/qrlydo8240u21.png?width=981&format=png&auto=webp&s=3882cac1c5cf705230a1a8182420f27ec55f8e04

Winlogon is the process responsible for the session of the OS user (provide logging in and logging out of the system). When booting the OS, Winlogon starts what is written in the Shell key, that's why the malware is launched.

In line 9, again there is a check for the presence of elevated rights and if it's not true, then the malware makes privilege escalation (line 10). How does malware do it? This is done by adding itself to the registry branch HKCU\\Software\\Classes\\mscfile\\shell\\open\\command. All that is written to this registry branch will be launched when opening files of type .msc. Next, malware runs eventvwr.exe - a Windows system utility that runs the Microsoft Management Console (mmc.exe), which immediately loads the .msc file. The magic is that eventvwr.exe is compiled with autoElevated = True in the manifest, which allows it to run with elevated rights bypassing UAC and not showing the user a window requiring consent to run. Thus, Sepsis launches itself SECOND time.

In line 11, the malware falls asleep and the second instance comes into play. The first instance, after hibernation and checking in line 12, stops in line 15. The check for restart occurs by creating a mutex with the unique name HJG>
https://preview.redd.it/uql9fbv640u21.png?width=1064&format=png&auto=webp&s=c5a30221d139ed729cf4b846c7ab0612eac7e628

Now, we will analyze the work of malware after restart. As we see, the first launch was necessary to add to autorun and launch itself with elevated rights. After running in elevated rights, the malware brazenly copies itself to C:\Windows\svchost.exe, without generating any pop-up windows.

https://preview.redd.it/d59mb45a40u21.png?width=654&format=png&auto=webp&s=0930a95148b8f42b025cab9f8cab2edf2c191c1e

As we can see, after running CopyFile, the file C:\Windows\svchost.exe has the same hash as the original file.

https://preview.redd.it/im4v94tc40u21.png?width=677&format=png&auto=webp&s=002a7d6596beb4430be7b519e886da10d97b1032

Line 16 encrypts all files, except files in folders:
Windows MSOCache Perflogs DVD Maker Internet Explorer Reference Assemblies Windows Defender Windows Mail Windows Media Player Windows NT Windows Sidebar Startup Temp Program Files Program Files (x86) 
The public keys (that we saw in previous static analysis) was imported

https://preview.redd.it/wfhjxyqj40u21.png?width=493&format=png&auto=webp&s=aada6cc887448383ac50708a95efe5e6c936b6c6

Files are encrypted using the CryptEncrypt function.

https://preview.redd.it/d3hj9adp40u21.png?width=400&format=png&auto=webp&s=143d11973c33493c4322152f6406af95ec250842

Line 18 deletes all existing backups, using the command we saw earlier - /c vssadmin.exe delete shadows /all /quiet & bcdedit.exe /set {default} recoveryenabled no & bcdedit.exe /set {default} bootstatuspolicy ignoreallfailures. This is done so that the user cannot recover the encrypted files.

Line 19, by calling the RtlSetProcessIsCritical undocumented function, the main process of Sepsis become system process. When the malware completes its work it completes its process and since it is system process OS crashes and reboots.

Line 20, for each existing disk in the system, an additional thread is created that renames all files in each folder with the exception of the list above.

Line 21, a file with html content (that we saw earlier) is created and displayed to the user.

System Restore

Delete infected files %TEMP%\svchost.exe, C:\Windows\svchost.exe
A unique pattern of malware sample is the name of the mutex - HJG>

I think I understand the basic idea here... but let me know if this is a viable way to use Tails, or if I'm actually an idiot.

EDIT: I realize the folly of trying to use Tails in a VM. so im throwing that idea out the window.
So if I set up a Tails OS in persistence on a USB, can I boot that from Virtualbox? And would I lose bitcoins left in the Electrum wallet if I restarted Tails in this state?
Additionally, will this compromise any anonymity if I'm running VB from a win10 setup using a local account, having telemetry and all that junk turned off, using a VPN, then on the VM have Tails running Tor.
The reason I want to do it this way is I have all my encrypted password files on my win10 setup so I can easily copy in my credentials and PGP info when logging in. If I boot to Tails from my PC directly, I lose this simplicity. Its not the end of the world if i need to just suck it up and manually type it all. But if this sounds like a safe setup for a newb not looking to do very much, let me know.
I don't wanna overdo my opsec to a point where I don't understand it. I feel like that could just make it less effective. But I don't want it to be so simple that I expose myself.

Help: Bitcoin Core does not auto start in Ubuntu with -datadir option

Please can someone help me out?
I have installed Ubuntu in VirtualBox to host Bitcoin Core. In VirtualBox I assigned a special disk with the blockchain. I am however new to Ubuntu. I am a Windows crack.
When I start bitcoin core from a terminal command prompt like:
bitcoin-qt -datadir=/media//Blockchain
then Bitcoin core starts correctly. "" is my username to login to Ubuntu. "Blockchain" is how the disk is named in VirtualBox. The host system is Windows 10.
However when I configure this command in the 'startup applications' of Ubuntu to start bitcoin core automatically when Ubuntu starts, I get the error message the path cannot be found.
While I am writing this post, I think it may be possible Ubuntu did not logged me in under username yet when auto starting bitcoin core, but this is a wild quess.
Is there an Ubuntu crack who can help me out please?

Comprehensive and honest user feedback from a Golem User

Hey everyone! Last week, a reporter approached us for words on Golem, and it was the first time a journalist actually also asked us to connect with a user for feedback. I told them to chat with PSVjasper99 and he provided super great feedback. He sent it to me and I shared it with our team, that appreciated it a lot. We consider your feedback extremely important, so posting here the report he prepared, and hoping to kick off a round of further feedback from all the Golem community. Thank you in advance!
__________________________________________________________
Experience Golem
Jasper V. 15-8-2018
I came across Golem around August of last year. A little background first:
I was starting my first semester at university that year and was already interested in the whole cryptocurrency world. At first, like many, I was full of scepticism. I mainly knew Bitcoin from being used on the darker side of transactions. Right as I started to learn about Golem, which was pretty much under pressure since their first major release Brass Beta was due summer 2017 and had not come out yet, I started my new study at the Technical University. One of my first major subjects required me to run tasks and complete FEM analyses on my university laptop (I study mechanical engineering and materials). These took days to complete. That was the point I bought my first Golem tokens. The use was to use these tokens if in the future, CAD renders and FEM analyses were to be implemented into Golem. Of course, the magic month December came and we all know what happened. I continued to hold on to my tokens and accumulated some more between March and now. Never sold nothing.
Of course this was at first all based around speculation. I first installed testnet in November (I think it was). What I first realised was that it was pretty spectacular the way it worked. The UI was clean and organized, instructions were clear and off rendering we went. This did not always go to plan however, because many of the tasks timed out. This was however, not a major problem since Golem allowed to use tGNT for testnet so we could attempt tasks as many times as we wanted. Updates came along every three weeks or so. The main files I rendered were demos that were also provided to test the capacity of the network. I had a success rate of about 25-35% estimated. A lot of tasks timed out or had a few ‘stripes’ not rendered correctly.
When Golem Brass Beta was launched about 4 months ago, I think the whole community was very excited. I only run Golem when I am actually using my PC. Running Golem whilst not using your PC would not only be very inefficient, but expensive too. It is not like mining. At the moment there is a clear deficit in requestors as opposed to providers. People should not expect when they launch Golem, that is computing the whole time (yet!). I have had days with tens of tasks with some good rewards, about 6 GNT per day, and days after which I had not had a single task ever since. Therefore, I often use Golems ability to change hardware allocation a lot. As I’m typing this, I offer 6 of my 8 threads to Golem. When I am gaming, I allocate 4 of my 8 threads and when I’m playing intensive games or VR, I allocate 2 of my 8 threads. My RAM and SSD space is always on full, since I have enough of that and it does not really impact performance that much.
I have now completed about 200 tasks across two nodes. Seeing how Golem actually worked was pretty cool and it has come a very long way since testnet and continues to improve. Golems UI is very smooth and I really like the vertical placement of the window. The application starts with a clear introduction, ability to protect your node with a password (access to wallets), and clearly tells you what to with port forwarding etc. This does not always go well, we see a huge surge of people on Reddit and the Golem Rocket Chat who have problems configuring their ports and connections. Thankfully, there are a lot of active team members and enthusiasts on the Rocket Chat who always find a solution. A major thing that has improved are the pop-up messages when hovering over items, and the understandeability of the whole application. Everything is well documented in the help document provided and the application works smooth without stuttering. Tips are provided as well for using the right settings when requesting a task on Golem, concerning task timeout, amount of subtasks etc. The price is basically determined via supply and demand, which is an advantage and could as well be a disadvantage. I hope Golem becomes large enough to not be influenced by big players making price agreements and who could, in theory, manipulate the market. However if this is not the case, this system ensures that the price paid for the computation is fair.
However, Golem certainly has its flaws. Not all of these were noticed by me, but I also talk to some enthusiasts and friends daily that always have Golem running. Most likely the team is working on these problems:
However, does this impact the implication of Golem in the real world? I have no idea. Golem currently only has Blender rendering POC on Mainnet and the target audience for requestors is not that huge. However, with the next release that should increase. Therefore, I don’t see an average Joe use Golem in the near future, but if more types of computation would be implemented, that could certainly change. If prices remain competitive, there is a huge (growing!) market available to Golem. Whether there is a hurdle for people to go to dApps from regular apps, probably. I think the majority of the projected users don’t quite yet see the added value of decentralization. Furthermore, I can imagine people disliking the fact to go to an exchange and exchange fiat for BTC or ETH, then to exchange for GNT, and then to transfer that GNT to Golems app. Golem is aware of this and I can see this (for many dApps) be the main factor contributing to the (not yet) mass adoption of dApps. Furthermore, the ever-changing value of these tokens is what might scare people off.
I am not a Blender artist and therefore I am not really able to use golem as a requestor. I can occasionally run some demo files. I have therefore not used any regular apps that provide the same service. Hopefully, this will change in the future, with the implementation of more use cases and the opportunity for the community to build on top of Golem.
So to conclude, will dApps ever replace regular apps? I see a few reasons as to why they might and a few reasons as to why they won’t. The main key is to improve the number of use cases, as well as the availability, keep the price competitive and the usability up. First, the issues above need to be solved for Golem specifically from my point of view. Some proper marketing could not hurt as well, trialling at universities and companies. If dApps are adopted by a few large(r) players (with the right use cases), domestic (mass) adoption could follow. However, I think it is hard to comment on this seen as the technology and development is still taking baby steps. I hope there is much more to come!

[QUESTION] Is Monero intended to be exceptionally difficult to set up?

I've had two frustrating days trying to get a monero node running. I'm hoping a kind redditor might be able to point me in the right direction. I'd love to give Monero a try, but I'm slightly shocked that the cryptocurrency whose primary value is anonymity has no easy anonymous way to send and receive transactions.
I would call myself a power user; comfortable in the command line but by no means an expert. I am at a slight disadvantage using a 32-bit Windows machine, but I really don't think that should be a deal-breaker. I've given a near herculean effort to set up Whonix in VirtualBox and troubleshoot the configuration to get that working. Once I finally got the Monero GUI working inside the VM, I realized syncing would take around 3 weeks straight, but it was getting slower as I let it run. Even a remote node sync was set to take weeks. My internet connection is plenty fast, but Whonix inside VirtualBox is not.
I downloaded the blockchain manually and got it onto the VM, which had its own handful of challenges. Apparently the nondescript errors the first time meant the blockchain file was being updated at the exact time I downloaded it. So the file was corrupted even though it downloaded without issue or error. A second download solved that issue an hour or two later, but now my VM is at 40 GB since it can't reclaim the space. Importing via the CLI has been equally frustrating. After overcoming those hurdles, it became clear that the import using the downloaded blockchain would be even longer than 3 weeks. It was importing blocks at a pace of 10 every minute or two. At this point I gave up the VM approach about a day and a half in.
I tried Tallow to route my Windows traffic through Tor. I have not been able to get this to work. I have not been able to figure out how to compile torsocks to run on Windows, meaning I can't run the CLI natively. Probably the most frustrating of all is that mymonero.com is blocked over Tor which would be the easiest option by far (though I'd still prefer a node). This has left me with no anonymous options to use the anonymous currency...
Is every Monero user running Linux or am I missing something? This has been exceptionally difficult with probably 50 hurdles to jump through thus far. Bitcoin Core just works. I don't understand why this has to be so difficult.

Running Bitcoin Core in Linux Subsystem for Windows?

I haven't use the Linux Subsystem for Windows yet, but I'm thinking about getting it set up to run a LN node. I'm already running the Windows binary for Bitcoin Core, but I'm thinking about switching it to run on the Linux subsystem so I can build it locally.
Anybody have experience with the core client or a LN node on this? Anyone know what the trade-offs would be compared to running a linux virtual machine in VirtualBox or something?

I have 1.5 or such ETH on the Rinkeby Test Net on Metamask...nobody is giving me a straight answer on how to move that to the the main ETH network.

All the posting I've done on Minds, I tried to make them as quality articles or links to music and videos that are part of what I'm willing to put effort into.
People over there have tried to help me,although one asked for my keys saying he would do the transfer himself...hm no, I'm not easily fished, I'm on the internet since 1997, before the internet became known as "social media".
Anyway, I want to move my stuff from that Rinkeby Test Network, when Minds ran on that, I had my Minds detect Metamask and my tokens went into My Onchain and Receiver address, which are the same when things are normal, iot about 20 tokens in Offchain, basically that ETH I can't move. I've been given guides, help on the Help group and the MindUsers group but what they say doesn't check out with reality, I've shown them screengrabs....it's just not working. Have 500 USD worth of ETH and it seems like it wa practise ETH/tokens that do not count because Minds was in Beta mode afaik is what I'm starting to think. My wallet address is the same on Rinkeby and Main, which I know is normal. Metamask is supposed to main everything easier, but even trying to do it outside of Metamask doesn't work, like giving the task to the people at Minds who will do it for me, when I click transfer after inserting my wallet address, no message that it gets taken care of.

I'm rather mad, there's this issue on Minds, and Steemit says a free account takes 1-2 weeks to be given, I have an account where I gave them my phone number for their damn SMS verification to consider me for a free account, it's been 6 months, no damn email activation like they told me I would get.I even had to try other of my email addresses with friends cell phones to get the SMS and nope, those 3 other accounts I made, with different IP addresses, that I keep within my real country so they don't think it's a suspicious request and ignore it, although one might have been done with me being on my VPS which is in the USA, although even things like Maxmind can't figure out its real location, that's some great sec from them, it says I'm in Canada even when I look up the IP on THE IP address info website/API,

I'm really aggravated by the situation. With crypto too. I had mined for 800 USD worth of Dashcoin through minergate and close to 2 fantomcoin since it could mine both cryptos at the same time and since I wasn't able to have dashcoin-linux or dashcoin-windows sync (it's a local DSH wallet), the a-holes at minergate stole all of my DSH by August 31st, no warning they would stop supporting DSH and 1 month to move it elsewhere, likely knowing it's a crypto that isn't in many good local or even online wallets, I couldn't find a single place to move the DSH too. It's a shitload of power drawn from me to have 800 something DSH, since it's not worth much, but it's the coin I could mine the second fastest, through commandline while in Windows 7 (I dual boot Mint 17.3 and Win7, although I might soon just have a Win7 virtual machine in virtualbox...I don't boot in it enough to warrant it at this point pretty much and run most of my games through Steam or CrossOveWine. Anyway getting away from the subject. I can only mine Monero really efficiently through CryptoMiner for AMD GPU and my AMD Radeon HD 7870 and a Radeon HD 7850 connected to work together with CrossOver, I get real decent Monero mining, also Ethereum since I got an AMD-FX8350 overclocked to 4.2ghz for all 8 cores, not anything crazy, but I got great cooling. I would eventually move the ETH I mined on that other place (not minergate) and the real luck I had when I mined 0,0017 Bitcoin Gold, I know my graphic cards are getting old hence my interest in being paid for my efforts to be relevant online and it seems like I can't get that either.
