Python sctp模塊 - 服務器端

Question

我一直在嘗試爲網絡部署測試SCTP。 我沒有SCTP服務器或客戶端，並希望能夠使用pysctp。

我相當肯定我有客戶端代碼工作。

def sctp_client(): 
    print("SCTP client") 
    sock = sctp.sctpsocket_tcp(socket.AF_INET) 
    #sock.connect(('10.10.10.70',int(20003))) 
    sock.connect(('10.10.10.41',int(21000))) 
    print("Sending message") 
    sock.sctp_send(msg='allowed') 
    sock.shutdown(0) 
    sock.close() 

有沒有人有幸在服務器端使用python sctp模塊？ 先謝謝您！

我知道這個話題有點過時，但我想我會迴應它來幫助社區。

一言以蔽之：您正在使用pysctp與插座包來創建客戶端或者服務器

• ;
• 因此，您可以像平常使用常規TCP連接一樣創建服務器連接。

下面是一些讓你開始的代碼，它有點冗長，但它說明了完整的連接，發送，接收和關閉連接。

您可以在開發計算機上運行它，然後使用像ncat工具（nmap的實施netcat）連接，即：ncat --sctp localhost 80。

事不宜遲，下面的代碼... HTH：

# Here are the packages that we need for our SCTP server           
import socket                     
import sctp                      
from sctp import *                    
import threading                     

# Let's create a socket:                   
my_tcp_socket = sctpsocket_tcp(socket.AF_INET)             
my_tcp_port = 80                    

# Here are a couple of parameters for the server             
server_ip  = "0.0.0.0"                  
backlog_conns = 3                    

# Let's set up a connection:                  
my_tcp_socket.events.clear()                  
my_tcp_socket.bind((server_ip, my_tcp_port))              
my_tcp_socket.listen(backlog_conns)                

# Here's a method for handling a connection:              
def handle_client(client_socket):                
    client_socket.send("Howdy! What's your name?\n")            
    name = client_socket.recv(1024) # This might be a problem for someone with a reaaallly long name. 
    name = name.strip()                   

    print "His name was Robert Paulson. Er, scratch that. It was {0}.".format(name)    
    client_socket.send("Thanks for calling, {0}. Bye, now.".format(name))       
    client_socket.close()                   

# Now, let's handle an actual connection:              
while True:                      
    client, addr = my_tcp_socket.accept()              
    print "Call from {0}:{1}".format(addr[0], addr[1])           

    client_handler = threading.Thread(target = handle_client,         
             args = (client,))          
    client_handler.start()
