Hi Ralph

This script works a treat.

Thanks

Looks like your proxy requires authentication via Kerberos or NTLM or GSS-Negotiate.  Dunno if Xymon can do those.  Luckily the curl tool (httpp://curl.haxx.se<http://curl.haxx.se>) *can* do those...  I haven't had to use them, but it should not be too hard to bang out an ext script to do the check.  Something along these lines:

     #!/bin/sh
     curl -x http://ourproxy.ourdomain.com:8080 \
           --proxy-anyauth -U hobbituser:hobbitpassword \
           -s -S -L -o /dev/null http://www.google.com/
     if [ "$?" -eq "0" ]; then
       COLOR=green
       MESSAGE="Pinged Google OK"
     else
       COLOR=RED
       MESSAGE="Failed to reach Google"
     fi
     $BB $BBDISP "status www,google,com.home $COLOR `date`
$MESSAGE"

Obviously that can be expanded quite a lot...  :)  Drop it somewhere on your Xymon server (maybe in server/ext) and set up a block in server/etc/hobbitlaunch.cfg to fire it off as often as you want.  You may need to give the full path for curl, which is probably /usr/bin/curl.

Hi all

I am trying to test our interent connectivity by checking Google through our proxy.
(Once I get this right, I want to start testing some of our external web pages in the same manner)

I have configured this in bb-hosts
0.0.0.0<http://0.0.0.0>         www.google.com<http://www.google.com>          # noconn http://hobbituser:hobbitpassword (at) ourproxy.ourdomain.com:8080/http://www.google.com

And I get this.
yellow<http://hobbit/hobbit/gifs/yellow.gif> http://www.google.com.au/ - Proxy Authentication Required

HTTP/1.1 407 Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied.  )

Any assistance appreciated.
