I want to download all mib files from the web page:
http://www.juniper.net/techpubs/software/junos/junos94/swconfig-net-mgmt/juniper-specific-mibs-junos-nm.html#jN18E19

All mib filenames are of this format:
www.juniper.net/techpubs ... .txt

I write this program but has the following error.
Please help.
Thanks.

#!/usr/bin/env python
import urllib2,os,urlparse
url="http://www.juniper.net/techpubs/software/junos/junos94/swconfig-
net-mgmt/juniper-specific-mibs-junos-nm.html#jN18E19"
page=urllib2.urlopen(url)
f=0
links=[]
data=page.read().split("\n")
for item in data:
    if "www.juniper.net/techpubs" in item:
        httpind=item.index("www.juniper.net/techpubs")
        item=item[httpind:]
        #print "item " + item
        ind=item.index("<")
        links.append(item[:ind]) #grab all links
# download all links
for link in links:
    print "link " + link
    filename=link.split("/")[-1]
    print "downloading ... " + filename
    u=urllib2.urlopen(link)
    p=u.read()
    open(filename,"w").write(p)
