    <p>Trying to build a simple file transfer with sockets on Python. I got stuck and it seems that I can't send any part of the file.</p> <p>Following some advice, I've tried to send the last line of the file, so I can know when to finish the connection. </p> <p>But it happens that once I send the first package, the client never gets the rest.</p> <p>Here you will see my code (Server side):</p> <pre><code>import os import socket PORT = 8080 HOST = 'localhost' socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) socket.bind((HOST,PORT)) socket.listen(10) conn, addr = socket.accept() print '\033[46m\033[34m\033[1mBienvenido al File Sender v.0.02 hecho en Python. Este programa permite enviar archivos a traves de tu maquina\033[0m' ANSI_RED = '\033[31m' ANSI_BLUE = '\033[34m' ESCAPEANSI = '\033[0m' def seleccion_path(): PATH = raw_input('\033[34m\033[1mSelect the Path (./ by default)').strip('n') if PATH == '': PATH = os.getcwd() print PATH, ESCAPEANSI acepta_path = raw_input('\033[34m\033[1mSi o No (S/N)').lower().strip(' ') if acepta_path == 's' or acepta_path == 'si': return PATH else: seleccion_path() def filesDir(path): files = os.listdir(PATH) for fl in files: i = int(files.index(fl))+1 print ANSI_RED + str(i)+ ')' + fl return files PATH = seleccion_path() print 'el PATH seleccionado es:', PATH + '\n' filesDir(PATH) fileSelected = int(raw_input(ANSI_BLUE + 'Select a file with the number').strip(' ').lower()) print PATH + filesDir(PATH)[fileSelected-1] fileToSend = open(PATH + filesDir(PATH)[fileSelected-1], 'rb') qLines = len(open(PATH + filesDir(PATH)[fileSelected-1], 'rb').readlines()) finalLine = cpfileToSend.readlines()[qLines-1] conn.send(finalLine) while True: data = conn.sendall(fileToSend.readline()) conf = conn.recv(1024) print conf if conf == 'OK': conn.close() fileToSend.close() break print '\033[43m File sent' #Finaliza el programa y deja los codigos ANSI cerrados print ESCAPEANSI exit() </code></pre> <p>Here is the Client:</p> <pre><code>import os import socket PORT = 8080 HOST = 'localhost' socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) socket.connect((HOST, PORT)) fname = open('./fileSent.pdf', 'w+') finalLine = socket.recv(1024) print finalLine while True: strng = socket.recv(2048) print 'aaaaa',strng fname.write(strng) if finalLine in strng: fname.write(strng) socket.send('OK') socket.close() fname.close() print 'Data received correctly' exit() </code></pre>

    1. COwhy are you sending last line at the beginning of transfer? I think it would be better to send the length of your file instead.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
