There's a lot of info you dont give us - so it'll be hard to give you a good answer

You say you have 8 IP, do they use ie point to point or udp ? do they expect a port number ? do they all connect and transmit at the same time ? what is the data protocol/format - you say ascii, but do you get/expect a connection from one of the 8 'clients', a fixed size packet of ascii data, then a close from the client ? how often/at what speed/frequency do the 8 clients send the ascii data to the server ?

"but no success" - why ? did you receive anything ? what did you implement on the server ?
