I have trying to learn how to do some basic networking and I have having issues using Putty. I am Connecting my server computer to the RS-232 via ethernet, and able to get the command prompt to display. However if i press enter, any characters or numbers I get nothing.
I've tried messing with the setting to see if i have something disabled. That hasnt worked for me so far, i also tried setting the speed from the default to 115200 to see if that would work either.
Am i missing a step that i need to do?

Unfortunately, I don't know what program is running on my CentOS 7 that is attacking brute-force through SSH.
What commands should I use to find the program or the ssh command executor?
An attempt to brute-force account passwords over SSH/FTP by a machine in your domain or in your network has been detected. Attached are the host who attacks and time / date of activity. Please take the necessary action(s) to stop this activity immediately. If you have any questions please reply to this email.
I used tcpdump and I expected the executor to also log the command, which it didn't do

I am trying to replicate an ubuntu OS which is has (NAT,Firewall etc) setup.I am trying to find away to install a preconfig os or the os image in production, to avoid installing and setting up manually in each and every machine.Is there a way to solve this problem?
Thank you
Two methods come to mind--both variations on a theme. There may be other better methods that others know of, but lets at least start with the following.
Method #1. Assuming that the hardware is exactly the same between systems, you may be able to copy an install from one disk to another (or clone it using 'dd').
Method #2. If you are using virtual machines, you may have a master copy that you copy as needed (instead of identical hardware, you have identical virtual hardware).

How can I solve it? Have no clue why that happens.
Given result
If I uncheck legacy mode the consoles stopped running: after opening the window freezes and nothing more happens (affect either PowerShell and command line):
Expected result
PowerShell and command line can be used in regular mode and are not rely to run in legacy mode.
If it runs in legacy mode but both Powershell and CMD freeze then there's probably something wrong with your windows install.
There's a variety of ways and programs you can use to try and troubleshoot (like Microsoft Sysinternals) but that's beyond the scope of what Stack Overflow is for
Here's a couple Stack Exchange sites you can ask for help troubleshooting the OS:
Super User for end user machines
Server Fault for network admins and servers

I have a problem probably totaly beginners level but anyway it drives me crazy so please help.
I can´t edit any code in the program when i try it looks like i´m in "insert" mode with like a block cursor.
I can´t delete anything or write anything. What could it be? and how do i fix it?
I am on a macbook pro.
I believe the reason is that you installed vim extension in vscode by mistake as it puts you in the insert mode by default until you press (i) to edit text. uninstall vim extension and things should go back to normal. or refer to this vim cheatsheet for more information about using vim as a text editor.

1st PC easily access virtual box.
but when i access with 2nd PC,1st PC automatically logout from virtual box.
using virtual box with remote access.
If anyone knows then please guide me.
Thanks
If your logging on as the same user on a server you are probably kicking yourself off with the second pc, try making another user account and logging on via it.
I don't think it is possible to do so as only one PC can logon to a user at a particular time. If you connect again, the first one gets disconnected.
For accessing the same machine/virtual machine at the same time, you need to create another user to do so.
