Proxy Auto-Discovery

I am in need of having student laptops over the wireless automatically pointed towards a proxy. One option I know is a transparent proxy, but we'd like to be able to let certain users opt out by changing the settings if possible. I found this option in the bootpd manual page:
dhcpproxy_auto_discoveryurl
I added it to my bootpd server by using NetInfo Manager:
dhcpproxy_auto_discoveryurl -> http://192.168.1.99/test.pac
At first I didn't think it was working, but I booted my MacBook Pro into my windows partition and sure enough it all seemed to work. Both IE and Firefox auto-detected the .pac file and started directing their traffic there. I boot into Mac OS X again and it's still not working.
Has anyone had any success with this option to deploy proxy settings? Is there an easier way that doesn't require me manually pointing 200 workstations to a .pac file on the internet? Is this simply a feature that doesn't work in Mac OS X 10.4?

You may need to configure the clients to use an auto-discovered PAC file.
If you look in System Preferences -> Network -> (interface) -> Proxies you can tell the OS to either use a PAC or use manual settings. It's likely that if you're set to Manual (the default) it ignores the DHCP PAC setting (although that's only a theory).
You may be able to automate this using networksetup, if it's installed on your systems (part of ARD). If it is you can:
<pre class=command>sudo networksetup -setautoproxystate "Built-in Ethernet" on</pre>

Web Proxy Auto Discovery (WPAD) fails in Creative Cloud

The Creative Cloud desktop application has a problem with WPAD automatic proxy detection. When the computer is configured to "automatically detect settings", the Creative Cloud application will not load the Apps list, giving the error "Download Error. Unable to reach Adobe servers. Please check your internet connectivity, firewall settings, and then try again." All other elements of the Creative Cloud application (logging in, accepting terms of use, the "Home", "Files", "Fonts" and "Behance" tabs have no issues using the automatically detected settings). I can refresh a netstat on the command line and see that the Creative Cloud application tries to make direct calls to the EC2 servers when attempting to connect to the "Apps" list instead of using the proxy.
If I manually configure a PAC file or manually configure the proxy on the computer, the Creative Cloud can connect successfully. The failure only occurs with "automatic detect settings". I have tested different WPAD server configurations, to include Apache on Unix, IIS7 on Windows, text/plain and application/x-ns-proxy-autoconfig MIME types, and CNAME vs A record for 'wpad'. Creative Cloud continues to fail to operate correctly.
The old version of Adobe Application Manager can successfully connect and download updates using "automatic detect settings". It will update itself (and installed apps) successfully. After it updates itself, it will connect and update itself a second time, this time replacing itself with the Creative Cloud application, which fails to connect. This behaviour is new to the Adobe Application Manager once it becomes the Creative Cloud application.
It seems from what "official" documentation I can find that this is currently "broken as designed" (see Adobe references at bottom of post). Connecting directly from a client to the internet without a proxy is prohibited by our information security policy (the chat support agent tried to tell me 3 times that the "solution" was to disable the proxy and open ports 80 and 443 to the internet). Manually configuring the proxy through a PAC file or manually setting proxy information causes other issues and performance problems (I strongly disagree with Adobe staff member Jeff Wright's assertion that automatically detecting the settings is "a common issue with most applications"--see reference at bottom of post).
While I could technically open the firewall or manually configure the proxy to make the Creative Cloud function properly, these are unacceptable workarounds as already stated. Considering that the previous iteration (Adobe Application Manager) functioned just fine with automatically detected settings, and that the rest of the Creative Cloud application functions properly with automatically detected settings, it seems that this should be a minor issue to correct with the application, to ensure that the application cataloging and downloading respects the same configuration as the rest of the client. What is the official Adobe position on the current broken functionality of the Creative Cloud application, and what is the timeline in implementing a fix?

Corporate environments: Configure Hardware firewalls or proxies
Many organizations use a hardware firewall and proxy server that can prevent software from accessing an FTP server. A hardware solution applies to all computers within the corporate network. Most home networks do not use hardware firewall or proxy technology.
1. Contact your company's IT department to obtain firewall or proxy information.
2. Configure your browser with proxy or firewall information.
3. Configure your corporate firewall to by-pass the servers. The following servers are accessed:
             ccmdl.adobe.com:80
             swupmf.adobe.com:80
             swupdl.adobe.com:80
Post from Adobe staff member Jeff A Wright (Reply 14: http://forums.adobe.com/message/5620841):
Quote: "The automatic detection of settings or the automatic configuration script is not currently supported. Although to be honest when I worked regular in an environment, which utilized a proxy server, this seemed to be a common issue with most applications. The manual configuration was the most reliable method of utilizing a proxy server and allowing the applications to access the Internet."

Thx! that worked! now I can download Apps.

Thx a lot

Access proxy from terminal using proxy auto-config

I know about using ntlmaps to wrapper my proxy configurations e get access from Terminal, iTerm2, &c exporting http_proxy variable and others. But I don't want go on using this approach because it simply ***** (forgive me for this word...) for a lot of issues.
I would like simply setup my proxy environment on Network Preferences/Advanced/Automatic Proxy Configuration: (host: http://myproxy/proxy.pac) and using this setup for a whole system, including my terminals. Therefore, are there any way to reach it?
Another details, my proxy is authenticated and uses ntlm type and in browser I use internet without problems.
Thanks a lot for any help!

I am not quite sure what you are looking for. Mac OS X has supported auto proxy configuration since 10.6 Snow Leopard was introduced (acutally in response to a request I made ). If you open System Preferences, click on Network, then go to the Advanced settings for your network interface, in the Proxies tab there is an option called Auto Proxy Discovery. This is different to Automatic Proxy Configuration which was also available in previous versions of OS X. Automatic Proxy Configuration uses a selected PAC file (Proxy Auto Configuration file) but Auto Proxy Discovery uses the WPAD method of finding your proxy server.
See this article for information about WPAD (Web Proxy Automatic Detection).
http://en.wikipedia.org/wiki/Web_Proxy_Autodiscovery_Protocol
WPAD uses either an option advertised from your DHCP server giving the address of your proxy server, or WPAD can use a standard URL based on your domain name to download a dat file containing your proxy server details.
I have seen reports saying the the DNS method is problematic with Mac OS X but also seen reports that the DHCP method does work with this option successfully. So my suggestion is to define the DHCP option code 252 to advertise your proxy server.
Note: Thanks to yet another request I made in the past the Mac OS X DHCP Server can be manually configured to define additional DHCP option codes including option 252. The ability to define DHCP option codes was added in Mac OS X 10.5 Server (Leopard).

Auto-discovery option..

In Weblogic we need to define the managed server in the administration server first for it to be a part of the cluster. Which means that if the administration server is not available for any reason the configuration of the cluster cannot be altered.
          Is there a concept of Auto-Discovery available in weblogic (similar to JBoss) where-in the cluster nodes are automatically converged into a cluster if the partion-name and the multicast IP address and port are the same within the same subnet.

A server can join a cluster if the admin server is not up, but all servers must be configured and the admin server is required for that.
          The usual deployment strategy would be to pre-configure all the servers you may want to run but only boot an initial set. Then there is no requirement for the admin server to be up.
          I'd have some concerns about the auto-discovery approach. We tend to be relatively conservative for production environments and wanting it to be extremely deterministic for admins.

Auto Discovery in CUOM

I have installed CUOM 2.2 and am trying to monitor a Call manager 4.2 cluster. I have configured all Call Manager servers with the SNMP string and host in windows services.
When I run an Auto Discovery in CUOM with the Publisher as the Seed Device I expected all CCMs, VGs and Phones to be discovered however CUOM discovered the Publisher only.
Can anyone advise what I have missed?
Many Thanks
Pete

I think it seems like SNMP string issues. Please check at both CUOM and Device side for SNMP.
check
1. Network connectivity between CUOM and device
2. Check SNMP are working fine at device side.
3. Check SNMP configuration at CUOM
If there is problem and is fixed, please rediscover the device in CUOM.

Do i need to package my tag handler in a jar file?no.
If
i put the full qualified uri in the jsp file like
this
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page"
xmlns:bmw="urn:jsptld:/WEB-INF/bmw-taglib.tld"
version="1.2">
it works perfectly, but i don't want to hard-code my
tld path in the jsp files or in the web.xml.you have two options:
1. you do not put anything about the taglib into web.xml. then you must use the path to the tld as URI. the path is relative to the root of the application. i think in your case you would have to use "/WEB-INF/bmw-taglib.tld" as URI and not "/test-taglib".
2. you introduce the taglib in the web.xml and then you are free what URI you use.
The specification in section JSP7.4.3 ("Implict Map
Entries from TLDs") sais, that an <uri> tag in the tld
is sufficient and a corresponding entry in the web.xml
is generated automatically.yes, option 1.

How to configure Auto Discovery in OEM 12c

Hi
I am new to OEM12c. I need to set up the auto email alerts through OEM 12c. through the Admin guide I have read the procedure.But I am not able to implement it. Can anybody tell me here the detailed procedure to add the managed target in OEM12c. We need to monitor mainly HCM domain form here. Please tell me the prerequisites also. When i try to configure auto discovery of host it asks me for host credentials but i ma not able to get for which credentials it is asking for.
Thanks in Advance

Hi,
Configuring notification rules in 12c is different from earlier releases.
The concept and function of notification rules has been replaced with a two-tier system consisting of Incident Rules and Incident Rule Sets :
1. Incident Rules: Operate at the lowest level granularity (on discrete events) and performs the same role as notification rules from earlier releases.
By using incident rules, you can automate the response to incoming incidents and their updates.
A rule contains a set of automated actions to be taken on specific events, incidents or problems.
The actions taken are for example : sending e-mails, creating incidents, updating incidents, and creating tickets.
2. Incident Rule Set: A rule set is a collection of rules that applies to a common set of objects, for example, targets, jobs, and templates.
To help you to achieve the Notification Rules configuration, refer those notes :

2012 R2 DirectAccess multi domain forest: Is it possible Limit Auto-discovery of domain controllers?

I've just successfully implemented Multisite server 2012 R2 DirectAccess in a child domain of a global company with numerous sub domains. I'd like to limit the scope of the auto discovery of management servers in 2012 R2 DA is anyone aware of
any way of doing this?
During the default initial configuration of DirectAccess Auto-discovery of domain controllers is performed for all domains in the same forest as the DirectAccess server and client computers.
In my scenario the number of sub domains and multinational nature of the company means that the DA servers cannot contact all DCs for every child domain in the forest.
This means the Operations Status page in the Remote Access Management console always shows the status of the Domain Controller check as "critical" leaving a red X amongst my nice green ticks. It's untidy and at first glance it looks like there
are major problems with the service.
The DA servers, Client machines and users are in a single sub domain so we have no need to contact the other child domain DCs.
I looked into using the Remove-DAMgmtServer PowerShell cmdlet however this is not applicable since it cannot be used to remove automatically configured management servers such as DCs.
Also the child domain DCs don't actually appear in the management servers list.

Hi, a colleague of mine had the same problem in a DirectAccess deployment in a large organization tat have a multi-domain forest. He had no choice to open network flow to have at least one domain controller per domain in the forest.

Android Email Policy - Username Auto Discovery

Is there a way to set the Username in Email Profile for Samsung KNOX Standard policy to
User Principal Name? Right now it is set to Auto Discovery and the email policy does not go through, but if I manually setup the email it will push through correctly when using the setting that would apply if I could select User Principal Name.
Thanks.

The Username field is fixed at "Auto discovered" and this cannot be changed. Intune automatically populates this field with the user principal name. This is different in iOS where you must choose between Primary SMTP and UPN.

Auto-Discovery of Tag Libraries

Has anyone of you got the auto-discovery thing of tlds running? Well, i have problems with it.
My tld resides in the WEB-INF directory and contains the following:
<taglib>
<tlib-version>1.0 EA2</tlib-version>
<jsp-version>1.2</jsp-version>
<uri>/test-taglib</uri>
</taglib>
-[eof]---------------------------------------
And the jsp page contains the following.
<%@ taglib uri="/test-taglib" prefix="test" %>
<test:getActive/>
-[eof]---------------------------------------
The same thing in XML sytax (Sun calls this JSP document :o).
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" xmlns:bmw="urn:jsptld:/test-taglib" version="1.2">
<test:getActive/>
</jsp:root>
-[eof]---------------------------------------
In both cases Tomcat 4.01 reports an error, when i try to invoke the jsp: org.apache.jasper.JasperException: File "/test-taglib" not found
Am i missing something?

Auto-discovery for TLD files in WEB-INF

The auto-discovery mechanism in JSP 1.2 can scan through the WEB-INF directory structure for files with .tld exntension and find all <uri> definitions in them, so we can use a symbolic name to map to the actual location of the tld file by using:
<%@ taglib prefix="test" uri="mytaglib" %>
in a JSP page.
My colleague and I did not have luck in making this work. I got the following error message:
"500 Internal Server Error
OracleJSP: oracle.jsp.parse.JspParseException: Line # 1, <%@ taglib prefix="test" uri="kltaglib" %>
Error: java.io.FileNotFoundException: C:\oc4j\j2ee\home\applications\myapp\myapp-web\mytaglib (The system cannot find the file specified) "
The symbolic name was not recognized. Is this a limitation in OC4J? Has anyone make this work? However, another way of auto-discovery by META-INF in JAR files works for me.
Thanks.

Proxy Auto Config Web Test Plugin - VS 2012

Hello,
I am hoping someone can help me with my problem. I've currently created a number of web tests which require a web test plugin in order to run. The issue that I am having is that our company proxy is via Proxy Auto Config file.
But I cannot find anything about passing this in to the WebProxy object.
Is there another option for me to pass the config file or url to the file so that my web tests will run correctly?
Thanks in advance for any help.

Hi Pir.Rad,
