I'm trying to write a simple script which will connect to a computer via telnet, run a couple commands (ehlo/vrfy) and get back the results. the purpose being i need to do this to verify if something exists already. I can get everything to work if i open a telnet window and manually do it but i want to be able to easily fire off this lookup tool as i need it. here is my initial tcpconnect test code: TCPStartup() $ip = TCPNameToIP("$domain") ConsoleWrite($ip & @CRLF) $Socket = TCPConnect($ip, 25) If $Socket = -1 Then ConsoleWrite('i die' & @crlf) Exit EndIf ; Sleep(500) $recv = TCPRecv($Socket, 500) $err = @error If $recv <> "" then ConsoleWrite('Received: ' & $recv & @crlf) else ConsoleWrite('got nothing? ' & $recv & ":: " & $err & @CRLF) EndIf $send = TCPSend($Socket, "help" & @CR) $recv = TCPRecv($Socket, 500) If $recv <> "" then ConsoleWrite('Received: ' & $recv & "::" & $send & @crlf) else ConsoleWrite('got nothing? ' & $recv & " :: " & $send & @CRLF) EndIf TCPCloseSocket($Socket) TCPShutdown ( ) the result of this block is : ###.##.###.### got nothing? :: 0 got nothing? :: 5 so $socket exists. tcpsend is sending 5 bytes successfully and even though i'm not getting anything back TCPRecv() is not setting @error so technically it should be working too. I can't seem to figure out why TCPRecv() isnt giving anything back but everything else seems successful.
