Created page with "Here are some scripts I've written for various purposes. =AirBearsLogin.py= While at Berkeley, I would use this following script to log in to AirBears (the wireless network). ..."

New page

Here are some scripts I've written for various purposes.

=AirBearsLogin.py=

While at Berkeley, I would use this following script to log in to AirBears (the wireless network).

<code><pre>
#!/usr/bin/python
#
# Replace USERNAME with your username and PASSWORD with your password.
# You may need to install the python mechanize module. The command
# sudo apt-get install python-mechanize
# might do the trick

try:
from mechanize import Browser
import re
br = Browser()
br.open("https://auth.berkeley.edu/cas/login?service=https%3a%2f%2fwlan.berkeley.edu%2fcgi-bin%2flogin%2fcalnet.cgi%3fsubmit%3dCalNet")
br.select_form(nr=0)
br["username"]="USERNAME"
br["password"]="PASSWORD"
page = br.submit().read()
errors = re.findall('<h2 id="status" class="error">[^<]*</h2>',page)
if len(errors)==0:
print "Logged into AirBears (probably)."
else:
for error in errors: print error[30:-5]
except IOError, e: print "Couldn't connect to wireless login page:\n", e
except KeyboardInterrupt: print "Ouch! Ok, quitting."

=unpnup=

A modified version of Harald Hackenberg's unpnup bash script for converting two-page-per-page pdfs into one-page-per-page pdfs.

I've stopped using this script in favor of the awesome program [http://sourceforge.net/projects/briss/ Briss].

<code><pre>
