Script Help

[rbrugman]

Hello,
I am in need of a script that runs once every minute, but I have no programming experience. Here is what I need it to do:

Once per minute I need the script to check this internal page:
http://192.168.0.50

I then need it to check the resulting page for the words "not yet initialized". If found, the script can end.

If not found, I need the script to run this command:
http://192.168.0.50/reload.html?Status=&Change=Change

I also need it to send me an email when this happens. Also, maybe a timeout in case my router goes down or something.


If anyone can help me out with this, I'd greatly appriciate it.

If someone could help I could even paypal a few dollars. I'm in serious need of this script.

Thanks,
Robert

you can write the script and then set up a cron job to run every minute. this will send you an email with the output of the script each time it is run.

I'd suggest a simple python script. The httplib module has a class HTTPConnection. This class has methods request and getresponse.
import httplib
conn = httplib.HTTPConnection('192.168.0.50')
conn.request('GET', '/')
r = conn.getresponse()
if "not yet initialized" not in r.read():
conn.request('GET', '/reload.html?Status=&Change=Change')
r2 = conn.getresponse()

Note: code is untested. Path variables may not need initial '/' - I don't know. There is emailing libraries too to do the emailing, but you should be able to add that without too much trouble.

Thank you for the script. I'm not familiar with cron (besides that it can run automated tasks). I can tell if its working so I can help test it. If you can help me get the emailing stuff working and the script works, I'll paypal you some money. If only I had taken a programming class before I desperatly needed a script.

If you don't want to, the offer is open to anyone that can help me get a working script.


Thanks!!!

crontab -e
will let you edit your crontab. an entry like the following should do what you want

* * * * * /full/path/to/script | mail -s "subject: output from script" myemailaddress@mydomain

I posted a crontab/cronjob how-to. you can see it here:

I have two other small things it needs to do. I don't really care about it emailing me as much, but I would like it know how to get it to recheck if it loads the second URL.

Thanks,
Robert
