[hobbit] Testing external web through a proxy

[Ralph Mitchell]

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) *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.
