Setting proxy server via dhcp

We would like the DHCP server to use option 252 to issue the proxy settings each time someone gets an address. I understand you have to create a proxy pac and store the file on a web server, but was wondering what the best way is to set this up as
we have multiple locations with the DHCP Servers.

Hi bubba1984,
Additional, you can refer the following specific KB and article for how to configure the proxy auto settings.

How can I tell if IE has received a WPAD configuration file when “Automatic detection” is enabled?

Automatic configuration does not support certain file types in Internet Explorer 8.0
The DHCP clients may not obtain the configuration script when you use DHCP Option 252 to automatically configure Internet Explorer

How to set proxy server name in iasenv.ksh?

How to set the proxy server host and port in the JAVA_ARGS list in the iasenv.ksh file? IAS 6.5 is the server being used.

hi,
Below is what needs to be done.
1. Edit the variable JAVA_ARGS in iasenv.ksh to include the -Dhttp.proxyHost. For example, the JAVA_ARGS looks like this : JAVA_ARGS="-Xss512k -Xms64m -Xmx64m -Dhttp.proxyHost=proxy.myhost.com -Dhttp.proxyPort=8080"
2. This JAVA_ARGS is the one under the kjs script settings. You will find this below the comment ## Set all user level JVM flags for KJS here.
3. Now stop and restart the application server.
4. Any new URL connections from the servlets/applications within the appserver will now go through the proxy server.
I have tested this on iAS6.0 SP3. But this should work in 6.5 too. Please let me know if this helps.
Cheers,
Vasanth

I haven't tested this, but if you type about:config in the address bar and search for "proxy" then you might be able to set the "network.proxy.http" and "network.proxy.http_port" preferences to the name and port of your proxy server.

Can't Set Proxy Server For AIM Account

Hi!
In the Messages application, the AIM account has a Server Settings tab where one can opt to connect using a proxy. However, with Mavericks I have found that anything I enter in that field is instantly wiped out. The console logs a message each time:
11/21/13 3:29:25.055 PM Messages[5215]: [Warning] *** API client requested a modification of key "ProxyHost" to be "myproxy", this is being ignored, please file a radar
where "myproxy" is anything one enters into the field.
Any advice?

Hi,
This issue goes way back in to the history of iChat.
It has never been that good at connecting using Proxies.
It has does slightly better if using the System Settings.
I don't use Proxies and so have never spent any time working though this.
Basically iChat and Messages connecting via a Buddy List is via the AIM servers but is almost Peer-to-Peer in process.
Connections are very linear particularly for Video and Audio chats to the extent that connecting to your router with Ethernet and Wifi is enough to cause issues.
Whilst starting up the app also contacts Apple to test bandwidth (Internet Speed) and support things ready for Video and Audio chats.
It is not just a case of Logging in to AIM.

Setting proxy servers via the command line

I am looking to find out how to set up the system to use http and https proxies via the command line instead of through system preferences. How do I do this. I have basic command line knowledge.

This information is stored in a plist file and is easiest to manipulate with PlistBuddy. For example, to set the HTTP proxy name, use:
/usr/libexec/PlistBuddy -c "Set NetworkServices:6CFBA910-E4A0-4418-82E5-66A6480EBC71:Proxies:HTTPProxy http://my.proxy.com" /Library/Preferences/SystemConfiguration/preferences.plist
Note: 6CFBA910-E4A0-4418-82E5-66A6480EBC71 is a UUID and likely to be unique on each machine. I don't have another Mac handy to check this. If so, you'll need to do some heavy to find out which one is the interface you need to address.
Try man PlistBuddy and/or a web search for more information on how this tool can be used.
Try man PlistBuddy or a web searc for more info on using it.

Setting proxy server when using Opera

I managed to set up a network location for my office, where we connect via a proxy, and for home, where there is no proxy. Safari correctly recognizes the proxy settings in each location, but for some reason Opera, my main browser, does not. As a result, I need to go into Opera's preferences each time to set the proxy settings. Is there an easier way of doing this?
Thanks for your time.

This is an Opera issue, so it would make sense to contact their tech support for assistance.

Cannot connect via proxy server

I need to use a proxy server in order to access university resources from off-campus. (This is set up in Firefox using Tools > Options > Advanced > Network > Settings > Automatic proxy configuration URL.) I have been doing this for two and a half years with no problems, but all of a sudden it doesn't work anymore. I have made no recent changes to my computer (Windows XP laptop) or browser settings. I get a connection has timed out / the server is taking too long to respond error message whenever I try to access a website via the university proxy server. This is only an issue for websites that require the proxy, such as databases that the university library subscribed to. I can access all public websites as usual.
I have tried Internet Explorer and get the same problem. If I disable the proxy server then my connection does not time out, I just get redirected to the university's "you are off campus and need to enable a proxy server to connect to this resource" page. University technical support tells me there is nothing wrong with the proxy server and that I am set up properly to use it, and that as far as they can tell the issue is probably with my ISP.
I am pretty sure this is indeed as Verizon issue, as I took my computer to a coffee shop and was able to access university resources via the proxy server just fine using the free wireless. I also got out my old laptop, reformatted the hard drive, reinstalled the OS (Windows XP), and had the exact same problem trying to use the proxy server via my home Verizon connection.
Incidentally, I am also unable to log in to Second Life using my home Verizon connection. I get an error message saying the server isn't responding. Again, I had no trouble with this using the coffee shop wireless.
I have spent about three hours trying to get someone from Verizon to address this problem, but keep being told I need to talk to someone else. I have now described this problem to ten different Verizon employees but have yet to reach anyone who even seems to know what a proxy server is, much less anyone who can help with this problem. If anyone out there has any suggestions, I'd much appreciate it. I cannot do much work from my apartment if I cannot access university resources.

That Trace suggests there is a firewall at play somewhere blocking ICMP Echo. Since it's timing out past the modem I do have reason to believe that the modem may be up to something. Visit http://192.168.1.1/ and check the Firewall settings. If it's set to Low or High, disable it. If you are prompted for a User/Pass, try the following:
admin/password
admin/password1
admin/admin
admin/admin1
Your Verizon Username and Password

Safari 3.x (Leopard) and Web Proxy Server Problems:

I have a Squid proxy server running on Linux. Users web traffic is directed through it via WPAD server which hosts a simple PAC file. The PAC files is very clean and small. It basically points all external (Internet) web traffic to our Proxy server. All of our Windows, Linux and Tiger clients work fine. However, Leopard (Safari 3.x) doesn't work quite right. Here's what happens:
Mac user logs into a Leopard 10.5 Mac. User launches Safari and tries to go to an external (Internet) site. The WPAD server is contacted and the Mac User is prompted to authenticate to the Proxy server. This is totally normal behavior thus far. Then, however, every few minutes the Leopard Mac user will be prompted to authenticate again (sometimes 2 or 3 times in a row!). Firefox 2.0.x, when configured to use the WPAD/PAC server and Proxy server, works fine in Leopard. Only Safari 3 in Leopard is having the problem.
All the Macs (Tiger and Leopard) are configured to use the Proxy server via OS X's Network Pref Pane (using the "Automatic Proxy Configuaration"). Reminder: Tiger works fine (even with the Safari betas), but Leopard's doesnt not.
I have attached our PAC file inline below (some things edited for privacy):
// SIMR automatic configuration for Mozilla and friends
// $Id: wpad.dat,v 1.8 2005/12/14 20:18:23 dct Exp $
// Edit carefully, since many may be relying on this...
function FindProxyForURL(url, host) {
// Bypass the proxy for internal addresses
if (!url.match("http:")
|| url.match("http://127.0.")
|| url.match("http://10.")
|| url.match("http://192.168.")
|| isPlainHostName(host)
return "DIRECT";
// These are exceptions given in the IE config for Windows.
if (host == "www.ncbi.nlm.nih.gov"
|| host == "chabry.caltech.edu"
|| host == "flybase.bio.indiana.edu"
|| host == "www.fedex.com"
|| host == "domain.org"
return "DIRECT";
return "PROXY <proxy server>:8080";
}

I think I have a similar problem. I am a Mac connecting to an otherwise all PC school network.
A new location with all correct proxies has been set up. However, Safari always crashes on first attempt to negotiate its way through our server to the internet. Internet explorer gets through because in its preferences it is possible to include the name of the school domain as well as my user name and password.
We have been unable to find any way of including the domain name into Location in Network or into Safari.
However, once Internet Explorer has negotiated with the server I can launch Safari and it works as normal.
Safari/Network seems to lack this option of including a domain name that my PC server requires.
Make sense to anyone?
Worth mentioning that my copy of Internet Explorer (5.2) often crashes, but usually it has done its job by then. I quite like the concept of Internet Explorer sacrificing itself to clear a path for Safari.

External proxy routing via MAC-LIST PERMIT

I have a school class where I want to provide internet connectivity.
Only certain computers should be able to connect to the internet, based on the allowed MAC address.
Of those who are allowed to connect to the internet, all browsing needs to go via an external proxy-server, for example ws.proxyserver.com:8080. Normally such an option can be set in the browser setup, but I would like this be set in the router.
Additionally, another computer should be able to access the internet without going via the external proxy.(Voip calls)
I saw that the CISCO 877 and PIX Firewall 501 and similar products that support the IOS CLI have the MAC-LIST PERMIT option but I don't know if and how the external proxy-server via can be accomplished.

Refer the command reference of the pix for more details about this command.

Mobile me/icloud find my iphone through a proxy server?

Hi All,
I'm not sure if this is the right place to post this so if it's not please let me know where is best.
I have a fleet of 600 ipads who are forced to run through a proxy server via a 3g connection. Up untill last week I could trace all these iPads via mobile me or icloud and use the find my iPhone feature. In this last week I seem to have lost this ability. All iPads are coming up with "no location". Mixture of iOS5 and variations of iOS4
If I turn off the proxy on the iPad I can trace the iPad.
me.com, apple.com amd icloud.com are all allowed through the proxy.
I cannot see anoy other banned traffic with a web address I can unblock.
I really just need to know what else I need to allow out via the proxy to get this working again? I'm guessing something has changed in Apple world as the proxy hasn't changed.
Thanks

Hi - did you have any luck with this? I have a similar problem, but only on a private APN through our proxy. I've managed to allow all the URLs to get the iCloud account registered for each device via the APN/proxy, but they do not appear on my icloud.com device view. If I remove the APN, therefore our network proxy is not used, it works fine.
Thanks

Certificate problem in Proxy Server (ODSEE 11g)

I am having a problem adding a CA Certificate to the Proxy Server. I followed the steps in the documentation, however I get the error: "keytool error: java.lang.Exception: Public keys in reply and keystore don't match".
From what I have read, this error means that the alias name I am using when I add the new certificate is already being used. As per the documentation...
When you request a CA-signed certificate, a temporary self-signed certificate is created. When you receive and install the CA-signed certificate from the CA, the new certificate replaces the temporary self-signed certificate.
... and this does happen. However when I bring in the new cert to replace... I get the mentioned error.
If I use a different alias, it doesn't give me an error. However, I can't see it when I use the "dpadm list-certs" command (although it is there when I use the keytool command). More importantly, the "defaultservercert" is still the certificate being used when accessing the server.
So the big question is... How do I get the Proxy Server to use the new CA Certificate?
I've tried using the keytool command in many different ways, and it fails each time. Lesson learned: don't mess with the keystore via keytool. Any changes made are not recognized by the Proxy Server.
I don't have access to this Proxy Server via DSCC because I do not have the password for the account running the services (a restriction made by the client), so it all to be done via CLI.
The operating system is Oracle Solaris 10 8/11 s10s_u10wos_17b SPARC.
Here are some outputs:

Hi Zulfiqar,
Please check the time difference between the proxy server and the ADFS server.

How do I send HTTP request to a server via a proxy server in JDK 1.4?

JDK 1.5 's URL class provides an overloaded version of openConnection() which accepts an object of type Proxy using which we can establish connection with a remote server via a proxy server, but JDK 1.4 doesn't provide any such overloaded version. How do I do that in JDK 1.4? Even if I had a class that can create HTTP packets for me, then I could have established Socket connection with the proxy server and sent the HTTP packet to it. Is there a way to do that also?

There are some system properties, which can be set with System.setProperty [http://java.sun.com/j2se/1.4.2/docs/guide/net/properties.html]

"do not use proxy server for local (intranet) addresses" IEM setting

Hi, i would like to find out where can i find the following setting in GPO which used be found in IEM.
"do not use proxy server for local (intranet) addresses" Enabled/Disabled
as currently im setting the IE proxy exception list via GPP, i don't see that option.

Hi,
As you notice that when we use GPP Internet Setting item to configure bypass proxy servers, there is no "do not use proxy server for local (intranet) addresses" option in GPP Internet
Setting item. However, as suggested by zanderol24’s reply, we can use bypass proxy server for local addresses option under
Proxy server to achieve the same function.
Best Regards,
Erin
