[D]python连接socket问题

[relateTarget]

很奇怪，同一份python的socket代码，在freebsd上的服务器运行client.py不能输出“welcome to server!”这句话，在另外一台centos的机子上有输出，这个跟代码有关还是跟服务器的配置有关？服务器的端口被封了，或者被占用了，是不是也是没输出？

if __name__ == '__main__':  
    import socket  
    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)  
    sock.bind(('127.0.0.1', 2131))  
    sock.listen(5)  
    while True:
	print 'reday!'
        connection,address = sock.accept()  
        try:  
	    print address
            connection.settimeout(5)  
            buf = connection.recv(1024)  
            if buf == '1':
		print 'welcome to server!'
                connection.send('welcome to server!')  
            else:  
		print 'please go out!'
                connection.send('please go out!')  
        except socket.timeout:  
            print 'time out'  
        connection.close()  

server.py

if __name__ == '__main__':  
    import socket  
    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)  
    sock.connect(('127.0.0.1', 2131))  
    #import time  
    #time.sleep(2)
    print 123
    sock.send('1')  
    print sock.recv(1024)
    print 456
    sock.close()  

client.py
