Subject:      Question about SockGetPeerName()
Content-Type: text/plain; charset="us-ascii"

Using OS/2 I have a script that is supposed to notify me if I get portscanned. The problem is that it always returns the address instead of the address I scanned from. What am I doing wrong? Any help will be greatly appreciated - here's the script..

/* Load REXX Socket library if not already loaded */ If RxFuncQuery("SockLoadFuncs") Then Do Call RxFuncAdd "SockLoadFuncs","RXSOCK","SockLoadFuncs" Call SockLoadFuncs End

/* create a TCP socket for client connection requests */ Socket = SockSocket("AF_INET", "SOCK_STREAM", "0")

/* find out local IP address */ Host.!addr = SockGetHostId()

/* Bind socket to well known port 1996 */ Host.!family = "AF_INET" Host.!port = 1996 Call SockBind Socket, "Host.!"

/* create a connection queue for 1 client */ Call SockListen Socket, 1

/* wait for a client to connect */ Say "Waiting for a client to connect..." ClientSocket = SockAccept(Socket) Say "Client has established connection."

xx = SockGetPeerName( socket, "address.!" ) say address.!addr

'call play file=c:\mmos2\sounds\starmed.wav' call lineout 'c:\work\log.txt', Date('e') Time() 'Scanned by' address.!addr
