Hello all,
I'm studying socket programming and have trouble when simulate a FTP server (I don't want to use pyftpdlib). The problem is when the client want to list the directory (LIST command) on the server, I do not find a way to send directory contents.
here is the code:
#!/usr/bin/python
from socket import *
host = "0.0.0.0"
port = 21
s = socket(AF_INET, SOCK_STREAM)
s.bind((host, port))
s.listen(1)
print "[+] Simple FTP Server Started."
print "[+] Listening on port %d ..." % port
cl, addr = s.accept()
print "- Connection accepted from %s" % addr[0]
def ftpserv():
dirlist = "drwxrwxrwx 1 100 0 11111 Jun 11 21:10 file1.txt\r\n"
dirlist += "-rw-rw-r-- 1 1176 1176 1060 Aug 16 22:22 file2.txt\r\n"
welcome = "220 Welcome to Simple FTP Server\r\n"
cl.send(welcome)
cl.recv(1024)
cl.send("331 User name okay, need password\r\n") # received USER
cl.recv(1024)
cl.send("230-Password accepted\r\n") # received PASS
cl.send("230 User logged in.\r\n")
cl.recv(1024)
cl.send("215 UNIX Type: L8\r\n") # received from SYST
cl.recv(1024)
cl.send("211-Features:\r\n") # received from FEAT
cl.send("211 End\r\n")
cl.recv(1024)
cl.send("200 Type set to I\r\n") # received from TYPE I
cl.recv(1024)
cl.send("200 OK\r\n") # received from REST 0
cl.recv(1024)
cl.send("257 \"/\" is current directory\r\n") # received from PWD
cl.recv(1024)
cl.send("227 Entering Passive Mode ("+addr[0]+",2521)\r\n")
cl.recv(1024)
cl.send("150 Here comes the directory listing\r\n") # received from LIST
cl.send("total 2\r\n"+dirlist)
cl.send("226 Directory send ok\r\n")
cl.close()
ftpserv()
s.close()thanks for the help :)
