Pac File Issues

[fil_b]

Hi All

 

I am having some issues with internal IP Address in my Pac File.

 

In the pac file the main address's work fine, 10.#.#.#, getting to printers in a web browser is not a problem.

 

But our VOIP has its own 192.168.0.# range, but this is not working. We have added two different coding in the file and neither work. I just get a search in Google

 

1st

 

dnsDomainIs(host, "192.168.0.*") ||

 

2nd

 

url.substring(0,10)=="http://192.168.0.*" ||

 

The 10 range works with the code below

 

url.substring(0,10)=="http://10." | |

 

Any thoughts please?

 

the url.substring code was supplied by BGFL. The dnsDomainIs was in the original file we used. Just not get the 192 addresses to work

 

Thanks

 

Phil

I've had a quick scour round the forums...

Some useful looking posts....

I'm sure someone else will know exactly what to do but I guess there's something for you to play around with there.

should you not be revising?

I'm allowed to take a few mins to browse the internet. ;P

url.substring(0,10)=="http://192.168.0.*" will never match - as the second string is longer than 10 characters. Needs to be 0,17.

 

Should probably be using "isinnet" tho...

whats isinnet??

[fil_b]

this is the file we was sent

 

//start

function FindProxyForURL(url, host)

{

if (isPlainHostName(host) ||

dnsDomainIs(host, "*.arthurterry.bham.sch.uk") ||

dnsDomainIs(host, ".bgfl.org") ||

dnsDomainIs(host, ".bgfl.eu") ||

dnsDomainIs(host, "myvle.org") ||

dnsDomainIs(host, "*misportal.net") ||

dnsDomainIs(host, "ats-ls01*") ||

dnsDomainIs(host, "ats-isa01*") ||

dnsDomainIs(host, "internet*") ||

dnsDomainIs(host, "intranet*") ||

dnsDomainIs(host, "192.168.0.*") ||

url.substring(0,10)=="http://10." ||

url.substring(0,18)=="http://192.168.0.*" ||

url.substring(0,11)=="https://10." ||

url.substring(0,9)=="ftp://10."

)

return "DIRECT"; //go direct

else

return "PROXY eduproxy.bgfl.org:80"

}

//end

 

 

this is our original file which we used

 

function FindProxyForURL(url, host) {

if ( isInNet(host, "10.134.32.0", "255.255.240.0") ||

dnsDomainIs(host,"https://webmail.arthurterry.bham.sch.uk") ||

dnsDomainIs(host,"http://www.arthurterry.bham.sch.uk") ||

dnsDomainIs(host,"ats-ls01.local.arthurterry.bham.sch.uk") ||

dnsDomainIs(host,"ats-ls01") ||

dnsDomainIs(host,"ats-isa01") ||

dnsDomainIs(host,"arthurterry.misportal.net") ||

dnsDomainIs(host,"intranet.local.arthurterry.bham.sch.uk") ||

dnsDomainIs(host,"intranet") ||

dnsDomainIs(host,"sharepoint.local.arthurterry.bhams.sch.uk") ||

dnsDomainIs(host,"sharepoint.arthurterry.bhams.sch.uk") ) {

return "DIRECT";

}

else {

return "PROXY eduproxy.bgfl.org:80";

}

}

 

any advice?

None of your "*" ones will work.

Think carefully about what you are asking - substr takes a portion of the string - you are saying "are the first 18 characters of the URL equal to "http://192.168.0.*" - which they will never be, the * there is literal. Try "are the first 15 characters equal to "http://192.168." instead

url.substring(0,15)=="http://192.168."

 

isInNet is the proper way to do it for IPs... you'll still need to "deal with" DNS names though - the browser doesn't resolve them - one of your examples takes a stab here:

isInNet(host, "10.134.32.0", "255.255.240.0")

 

That's fairly specific

isInNet(host, "10.0.0.0", "255.0.0.0")

 

would catch all 10. addresses

 

and

isInNet(host, "192.168.0.0", "255.255.0.0")

 

would catch all 192 addresses.

dnsDomainIs(host, "myvle.org") || 

 

looks suspiciously like an example

 

dnsDomainIs(host, "*misportal.net") || 

 

* won't work - replace it with a . to match all subdomains of misportal.net

 

 

dnsDomainIs(host, "ats-ls01*") ||
dnsDomainIs(host, "ats-isa01*") ||
dnsDomainIs(host, "internet*") ||
dnsDomainIs(host, "intranet*") || 

 

These are fixable - but I won't tell you how until you tell me why Its a really bad idea to put in prefixes - it could cause you all sorts of grief.

 

If you can give a good list of what you need to go direct, and what needs to go proxy, we may be able to help draw up a less confused proxy.pac

hi tom

 

Thats really useful information to help

 

What do i need to add to allow 192 address as well as 10.134 address's

 

Had a play to use 2 inisnet for 10.134 and 192, but it didnt work

 

i guess it didnt work

 

thanks

Bah. Had to make this "clever" didn't I

 

This will go direct for:

plain hosts (eg one word hosts like http://vle)

10.xx.xx.xx IPs

192.168.xx.xx IPs

anything ending bgfl.eu or bgfl.org

 

you can add new "endings" by adding another "push" line

 

Not tested in the wild, just with google's pactester.

 

function FindProxyForURL(url, host)
{
       if (isPlainHostName(host))
               return "DIRECT";
       if (isInNet(host,"192.168.0.0","255.255.0.0"))
               return "DIRECT";
       if (isInNet(host,"10.0.0.0","255.0.0.0"))
               return "DIRECT";
       var endings = new Array();
       endings.push(".bgfl.org");
       endings.push(".bgfl.eu");
       var t;
       for (t in endings)
       {
               if (host.match(endings[t] + "$"))
                       return "DIRECT";
       }
       return "PROXY eduproxy.bgfl.org:80";
}
