[Tutor] Passing HTTP commands through Telnet using Python for web site testing?
Hi, I just started learning Python and would like to try writing a monitoring script. What I would like to do is use Telnet to send a GET via port 80 to a status page in a directory to verify my site is up. Psuedo code: Connect = telnet website.com 80 Send = GET /folder/folder/test.asp HTTP/1.1 Host: website.com Pipe the Response to a file (overwriting it each time): HTTP/1.1 400 Bad Request Server: Server: Microsoft-IIS/5.0 Date: Wed, 16 Nov 2005 20:15:20 GMT X-Powered-By: ASP.NET Connection: close Server: website.com Content-Length: 102 Content-Type: text/html GREP "HTTP/1.1 400 Bad Request" from the file and | append >> it into a log. This tells me the connection was valid. Timestamping the line would be nice. The other error code could be "HTTP/1.1 404 Not Found" if the directory went missing or possibly "Cound not open connection" if the connection could not be made. If the above GREP is found in the file do nothing. If not send an email stating the error. End Anyway, Can someone point me in the right direction on getting the Telnet working? Or if you have a better way to get what I am trying to do accomplished. Is there a Python Telnet module?

Re: [Tutor] Passing HTTP commands through Telnet using Python for web site testing?
So far this is what I have come up with doing some research.
import urllib
for line in urllib.urlopen('http://mywebsit.com/folder/folder/test.asp'):
if '400 Bad Request' in line:
text_file = open("mysite.log", "a")
text_file.writelines(line)
text_file.writelines("\n")
text_file.close()
This writes the to a new line each time the script is run. Now I have
to figure out an "if then else" to write the other possible error codes
and appending a timestamp followed by a space each time it runs.
Thanks

[Tutor] smtplib alternative???
Hello, I found this script to send mail online. It works fine but requires me to enter an mail server. I'm looking for something else that doesn't require and SMTP server. Having to specify a mail server prohibits me from sending to alternate domains.

Re: [Tutor] smtplib alternative???
Hi Danny, Yes, when sending an email your mail client will always send the email to the mail server specified by the MX record in the authoritive domain. Usually the domain specificed after the @ symbol. The problem with smtplib is that I have to specify the mail server I'm sending email too. What if I wanted to send an email to 3 different people on three different domains hosted by 3 different mail servers? Smtlib prohibits this functionality. Do you see what I mean now...?

There is an 'smtpd' module that comes with Python: http://www.python.org/doc/lib/module-smtpd.htmlI'm also not sure I understand the reason you're trying to avoid talkingto an outside smtp server. But again, I'm unfamiliar enough with how theSMTP email protocol really works that perhaps I'm just overlooking something.-- Arthur DiSegnaNetwork Operations CenterAuthentium, Inc. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

I guess I should keep the same subject line (above)
from now on since my last few posts (urllib, smtplib) are about the
same program.
My question is how to use a loop to go through a tuple of URLs. Please feel free to suggest an easier way to do the same thing.
Here is my rudimentary program so far.
---
import urllib, smtplib
urls = ("http://website0.net/imalive.asp",
"http://website1.net/imalive.asp",
"http://website2.net/imalive.asp",
"http://website3.net/imalive.asp",
"http://website4.net/imalive.asp",)
# I added these just to make the loop work and be more readable
qa = urls[0]
n4k = urls[1]
metro = urls[4]
for i in urls: # <-- this obviously doens't work because I have to specify a value "metro" below
for site in urllib.urlopen(metro): #<- What can I use here to loop through the 'urls' tupple
good = "400 Bad Request"
bad = "Invalid Hostname"
smtpserver = 'mail.authentium.com'
RECIPIENTS = ['[EMAIL PROTECTED]']
SENDER = '[EMAIL PROTECTED]'
mssg = site
if good in site:
print "OK"
text_file = open("test.log", "a")
text_file.writelines('sometext : ')
text_file.writelines(site)
text_file.writelines("\n")
text_file.close()
elif bad in site:
print "NOT OK"
text_file = open("test.log", "a")
text_file.writelines('metro-ams : ')
text_file.writelines(site)
text_file.writelines("\n")
text_file.close()
session = smtplib.SMTP(smtpserver)
smtpresult = session.sendmail(SENDER, RECIPIENTS, mssg)
if smtpresult:
errstr = ""
for recip in smtpresult.keys():
errstr = """Could not delivery mail to: %s
Server said: %s
%s
%s""" % (recip, smtpresult[recip][0], smtpresult[recip][1], errstr)
raise smtplib.SMTPException, errstr
else:
text_file = open("test.log", "a")
text_file.writelines('Another type of error occurred : ')
text_file.writelines(site)
text_file.writelines("\n")
text_file.close()

How do I get the counting loop to come
back around? It makes one pass fine. How do I get it to come back up
and go through again?

I need to add the count statement to give urllib access the tuple of
urls. urllib needs to be given a different value each time in order to
check all the urls. This is the only way I could get the value (web) in
urllib to change each time. I tried indenting the count statement and
it runs without error but still only makes one pass.
Thanks

You
have to indent the statement 'count += 1' so it is part of the loop.
But you misunderstand the for loop - the count variable is not needed
at all. Your variable 'i' will receive each element of urls, one each
time through the loop. For a simpler example,
>>> u = ['a', 'b', 'c']
>>> for letter in u:
... print letter
...
a
b
c
So instead of
count = 0
for i in urls:
web = urls[count]
you can write simply
for web in urls:
