On linux, one can connect to a server by typing nc pwnable.kr 9000 on a terminal.

On windows, this does not work in Powershell nor cmd, and also Putty when using Telnet looks at first like it connected, and then whenever I enter something it exits, which is not the behaviour on Linux. So what is the correct way to access this server on Windows and send commands to it?

The Windows equivalent is Test-NetConnection - it will test if the connection to the destination works and show certain debug output.

Test-NetConnection -ComputerName superuser.com -Port 443

ComputerName     : superuser.com
RemoteAddress    : 151.101.193.69
RemotePort       : 443
InterfaceAlias   : LAN-Connection* 12
SourceAddress    : 10.254.93.150
TcpTestSucceeded : True

You may download a portable version of ncat from this site: https://nmap.org/ncat/ It's a beta version (http://nmap.org/dist/ncat-portable-5.59BETA1.zip). If you prefer, you may also use the nmap command for windows provided on this site too.

You can use "tnc" as shortening of Test-NetConnection in Windows Powershell. Legacy Windows command shell doesn't have any equivalent of nc (except third parties).

For example:

PS C:\Windows\system32> tnc haruncetin.com.tr -p 80

ComputerName     : haruncetin.com.tr
RemoteAddress    : 172.67.208.143
RemotePort       : 80
InterfaceAlias   : Ethernet 1
SourceAddress    : 192.168.215.119
TcpTestSucceeded : True
