Hi gurus,
Inspired from the "tiny featureless http server " message, I wondered
if someone worked on a minimal ftp server .
Actually, I’m interested in the way (s)he handled the PORT/PASV thing,
I mean:
Hi,
i am not a guru, but yesterday i wanted to see how an ftp server works,
so i wrote the following messy ftp client code. maybe you can glean
something from it:
require ‘socket’
def get_file(client_socket,filename)
file_acceptor = TCPServer.new(‘127.0.0.1’,5120)
client_socket.puts(“retr #{filename}\r\n”)
print client_socket.gets
select([file_acceptor],nil,nil,40)
s = file_acceptor.accept
str = s.gets(nil)
s.close
file_acceptor.close
print "received string size=#{str.length}\n"
str
end
def get_server_list(client_socket)
file_acceptor = TCPServer.new(‘127.0.0.1’,5120)
client_socket.puts(“nlst\r\n”)
print client_socket.gets
select([file_acceptor],nil,nil,40)
s = file_acceptor.accept
str = s.gets(nil)
s.close
file_acceptor.close
print "received string size=#{str.length}\n"
str
end
t = TCPSocket.new(‘localhost’,21)
msg = nil
begin
msg = t.gets
print msg
end while(msg !~ /^\d\d\d\s/)
t.puts(“user bill\r\n”)
print t.gets
t.puts(“pass mypasswd\r\n”)
print t.gets
t.puts(‘help’)
begin
msg = t.gets
print msg
end while(msg !~ /^\d\d\d\s/)
p get_server_list(t)
t.puts(“quit\r\n”)
