I'm having some issues with the black art of proxy autodetect scripts
(wpad.dat).  I'm having a tough time getting it to work consistantly.
I am
doing a phased roll-out of a squid proxy server, and want to the the
autodetect return "proxy:3128" for some ip addresses, and "DIRECT"
for
others.
The script works for some hosts, but not for others.  It works in the
first
couple of class C subnets mentioned, but it breaks down where the
specific
hosts are set to DIRECT (with the mask of 255.255.255.255), or
anywhere
below that in the script such as where 10.7.0.0/255.255.254.0 is
supposed
to be proxied.
Anyone have any suggesions?
code below:
################ wpad.dat ##############
    if (isInNet(myIpAddress(), "10.7.39.0", "255.255.255.0")) {
     return "PROXY proxy:3128";
       }
    else if (isInNet(myIpAddress(), "10.7.22.0", "255.255.255.0")) {
     return "PROXY proxy:3128";
       }
    else if (isInNet(myIpAddress(), "10.7.33.0", "255.255.255.0")) {
     return "PROXY proxy:3128";
       }
    else if (isInNet(myIpAddress(), "10.7.34.0", "255.255.255.0")) {
     return "PROXY proxy:3128";
       }
    else if (isInNet(myIpAddress(), "10.7.35.0", "255.255.255.0")) {
     return "PROXY proxy:3128";
       }
    else if (isInNet(myIpAddress(), "10.7.1.216",
"255.255.255.255"))
{
     return "DIRECT";
       }
    else if (isInNet(myIpAddress(), "10.7.1.217",
"255.255.255.255"))
{
     return "DIRECT";
       }
    else if (isInNet(myIpAddress(), "10.7.1.219",
"255.255.255.255"))
{
     return "DIRECT";
       }
   else if (isInNet(myIpAddress(), "10.7.0.0", "255.255.254.0")) {
     return "PROXY proxy:3128";
       }
    else {
     return "DIRECT";
   }

It looks like it should work.  Is it possible that the isInNet doesn't
work well with at "255.255.255.255" mask.  You could try
if (myIpAdress() == "10.7.1.216") instead.  I've never used it with
host
masks, just subnets.
Also define "breaks down".  Do those three host go through the proxy
but
the 10.7.0.0 ppl go out direct or do you get some sort of error?
Finally I've had issues where myIpAddress() returns the first IP listed
by ipconfig on Windows 2k laptops that were VPN instead of the PPTP IP.
 Never did find a workaround.

I will try using myIpAddress()== "10.7.1.216" and see what happens.  By
"breaks down" I mean that it seems that beneath the host, 255.255.255.255
lines does not bother to work.  I will replace the host/mask definition
with the myIpAddress()== "10.7.1.216" and see what happens.
Thanks

Excuse me for replying to myself.  The reason this was not working, as
mentioned by Billy above, is that the first IP listed by ipconfig is not
the IP address I had defined in the autodetect script.  Many of the windows
machines I had specified sit on multiple subnets.  Thanks for the tip
Billy.  I'll have to find another way to get this working.

Well at least you won't bang your head against the wall as much.  It 
sure was confusing me when I was trying to get it working.  If you 
figure it out please let me know as I eventually gave up.

Thanks,
Billy
