For yet another nifty UDP snippet see Skype-Style Firewall Busting with Ruby and UDP.





require 'socket'



#abort "Usage: server_addr, server_port, cmd_str" unless ARGV.length == 3



UDP_RECV_TIMEOUT = 3  # seconds



def q2cmd(server_addr, server_port, cmd_str)

  resp, sock = nil, nil

  begin

   cmd = "\377\377\377\377#{cmd_str}\0"

    sock = UDPSocket.open

    sock.send(cmd, 0, server_addr, server_port)

    resp = if select([sock], nil, nil, UDP_RECV_TIMEOUT)

      sock.recvfrom(65536)

    end

    if resp

      resp[0] = resp[0][4..-1]  # trim leading 0xffffffff

    end

  rescue IOError, SystemCallError

  ensure

    sock.close if sock

  end

  resp ? resp[0] : nil

end



# your firewall has to allow communication with IP address 67.19.248.74 (port 27912)

#server, port, cmd = *ARGV

server = "tastyspleen.net"

port = 27912

cmd = "status"



result = q2cmd(server, port, cmd)

puts result

Get the code for createhtmlmail(html, text, subject) here.



import smtplib

html = open("newsletter.html").read()

text = open("newsletter.txt").read()

subject = "Today's Newsletter!"



message = createhtmlmail(html, text, subject)



server = smtplib.SMTP("localhost")

server.sendmail('my@dress.com', 'your@dress.com', message)

server.quit()

import ftplib

s = ftplib.FTP('myserver.com','login','password') # Connect



f = open('todo.txt','rb')                # file to send

s.storbinary('STOR todo.txt', f)         # Send the file



f.close()                                # Close file and FTP

s.quit()
