Hello sir, glad to know that it works for you, I’m pretty sure that you have an issue with your quotation, should not be curvy, also you do not specify where the access control should return every request, same with the filter-on.
If you have any doubt, please let us know so we can help you!

Hi Carlos @thecil,
when Filip made the videos of EOS Programming 201, EOS still could not run in Windows. Now they have EOS Studio for Windows, it seems that under Network, one can also connect to Testnets such as Jungle, CryptoKylin, Block.one, can I create accounts and connect to testnet through EOS Studio without having to download VM to run Ubuntu and install everything through command window?
Hello sir, you could try to setup any of the testnet accounts that EOS Studio offers, so you will save time on installing a VM for ubuntu and use it has local node. Still, in EOS programming 201, we will teach you how to setup your own node. So is up to you which choice you take, or use testnets or run your own local node for the course
If you have any more questions, please let us know so we can help you!

ERROR
main.cpp:121 main ] database dirty flag set (likely due to unclean shutdown): replay required
when i try to start the node above error coming. Please help to solve the issue.
Hi @achinta_das, hope you are ok.
That error shows up most of the times becaue nodeos was not closed properly, every time you have finish work with your local node on EOS (nodeos) you have to close the software properly (in linux the command is pkill nodeos).
Check out on this guide on what you should do when facing this error:

Thank you for help . i am very new in EOS and development , can you help me with IOS command line
I do not own a MAC, but I think there are good quick tutorials for it, what you need to do is basically delete the content of your eos node folder (do not delete the entire folder, just the content inside of it.)
Here are some links that should help you understand it:

Then here is the CDT wget https://github.com/EOSIO/eosio.cdt/releases/download/v1.6.1/eosio.cdt_1.6.1-1_amd64.deb. then you all set! you will get a warning about whatever just ignore it. hope this helps folks.
thanks for the help filip.
Hello Everyone
I struggle to use yum to install the last rpm package in the Linux setup via VM on Windows.
I’ve managed to get a vm on Bionic Beaver running, i’ve installed the debian packages and get the CentOs rpm package.
Now when trying to install (sudo yum install ./eosio-1.8.1-1.el7.x86_64.rpm) I struggle with “yum”.
The command is not recognised (Error: “sudo: yum: command not found”) when researching I found, that yum isn’t installed automatically anymore and that I need to download an rpm package and install yum. I was redirected to https://pkgs.org/ but have no idea what exactly to download and when trying to install the yum-utils it doesn’t work either.
Has anyone or @thecil had similar problems or an alternative command to use for the last installation?
Thanks!
Hey @Konzaih, hope you are well.
CentOS is a linux distribution focused for servers (red hat), which is quite difficult to configure if you are new with Linux.
That way I advice you to download Ubuntu instead, 18.04 or 20.04, then you can use apt by default to install packages.
Take a look at my EOS repo that could help you as a guide for the installation for nodeos and cleos.

Hello @thecil
This was actually a great help, now I actually understand what I’ve misunderstood.
Thank you & have a nice day!
Sorry if i repeat myself but is there a way to start nodeos without the whole paragraph long load plugins, etc.? is there like a script? or is that just for the first time? when i try just typing in nodeos, it fails to initialize. is it looking for me to tell it to load all those plugins and things? help please! 
Indeed sir, i made a guide (for linux) long ago, same reason than you! Check it out:
Carlos Z
got it thanks for the help!
Thecil,
For some reason now I get this error below, before i would get an initialization error but I fixed that. did I uninstall something accidently? thanks for you help in advanced!!
I have been stuck on this course on this part for a long time
No idea what is causing it, tried googling…
I suspect something wrong with .viso, or…?
Hey @Gry, hope you are well.
The system image that you are using might not contain a bootable system.
You might need to download linux or a windows image (in iso format) that then you will boot with oracle vm.
PD: this course is quite outdated, you might run into other technical issues with the programs used over the course, also C++ programming knowledge is required, plus some additional knowledge to deal with outdated issues from the app.

Evening,
I see. I will be skipping to another course and wait for an update for this course.
