[Solution] Removing the Server-Tag from your homemade python's web server

( applies to BasicHTTPServer / SimpleHTTPServer / CGIHTTPServer )
Sometimes when you're playing to be a ninja in python and you got the crazy and sticky idea of build your own web server just for pass the time ;-). You may find some tricky things in the fly, things that maybe you would like to change like the “Server-tag” of your homemade python's web server :-) (that in my case says that is “Server: SimpleHTTP/0.6 Python/2.7.3”) so if you're stuck with that, here i pasted my python's script and leave my solution, i hope and it could be useful to you. :)

#!/usr/bin/env python

import SocketServer
from SimpleHTTPServer import SimpleHTTPRequestHandler

class http_handler(SimpleHTTPRequestHandler):
    def send_response(self, code, message=None):
        """\
        this is a copy-and-pase of the function send_response method in
        '/usr/lib/python2.7/BaseHTTPServer.py' file.
        in the code below i just edited the line
        "self.send_header('Server', self.version_string())"
        for my own to remove the Server-Tag in the Header. ;-)
        """
        self.log_request(code)
        if message is None:
            if code in self.responses:
                message = self.responses[code][0]
            else:
                message = ''
        if self.request_version != 'HTTP/0.9':
            self.wfile.write("%s %d %s\r\n" %
                                (self.protocol_version, code, message))
            # print (self.protocol_version, code, message)
        self.send_header('Server', "jimmy's python web server") # <= this line was edited 'cause i didn't
                                                                #    like the default Server-Tag in the Header
        self.send_header('Date', self.date_time_string())

server_addr = ('',8000)
httpd = SocketServer.TCPServer(server_addr, http_handler)
httpd.serve_forever()

My solution:
you must to override the send_response method (i copied it and pasted it all that code from it sources in /usr/lib/python2.7/BaseHTTPServer.py, so don't be scary ;) ) and overrode this line

self.send_header('Server', self.version_string())

with my own putting attention to the syntax. so This is my new line

self.send_header('Server', "jimmy's python web server")

if you have a linux distro, you can use the curl command to verify the changes when your server been running with this command in your linux terminal:

curl -v localhost:8000

and that's it!, hope to help. Feel free to left commentaries, doubts or corrections :)
see ya'!

[Solution] “socket.error: Address already in use” in python

yesterday in the evening i was writing a simple web server in python (2.7) and i got a socket error when i tried restart my “simple web server” so i digged a lot and few time later i found the answer, so here leave my python's script to fix that error.

#!/usr/bin/env python

import SocketServer
from SimpleHTTPServer import SimpleHTTPRequestHandler

class http_handler(SimpleHTTPRequestHandler):
    pass

class TCPServer(SocketServer.TCPServer):
    """
    this is a variable that may be overridden by derived classes or
    instances
    i found it at '/usr/lib/python2.7/SocketServer.py'
    """
    allow_reuse_address = True

server_addr = ('127.0.0.1',8000)
httpd = TCPServer(server_addr, http_handler)
print "listening on: %s:%d" % (server_addr[0], server_addr[1])
httpd.serve_forever()

and here is the explanation:
some forums says that you have to set the variable “allow_reuse_address” hosted in the TCPServer class to “True” with a magical

“myTCPServerInstance.allow_reuse_address  = True”

Note: that it comes from the very base class socket, where that variable it's a synonym of “socket.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR, True)” to set the socket address in reuse mode.
But it doesn't work! as easy like they says, so digging a few in the python's help (SocketServer's help) i watched that you must to override the variable “allow_reuse_address “ hosted in the TCPServer class with a value of True because by default it's False so here is the code that i overrode:

class TCPServer(SocketServer.TCPServer):
    """
    this is a variable that may be overridden by derived classes or
    instances
    i found this at '/usr/lib/python2.7/SocketServer.py'
    """
    allow_reuse_address = True

and that's it! to run the script you should use:

python webserver.py

in your terminal
