Hello, This is regarding to smb service we usually use for win-linux connectivity.... Now I have client application at Windows machine and server application at linux machine.... I have used socket for the connection... Smb : start connection using socket API-getHoseByAddress gives "connecting to IP" Smb : stop connection using socket API-getHoseByAddress gives "can not resolve IP" any other service we can use for same connectivity instead of smb ???? thanks regards....Naresh __________________________________ Do you Yahoo!?
