Configuring authentication in web proxy server

We are using iPlanet Web Proxy Server 3.6 on WindowsNT 4.0
After installation of iplanet web proxy server 3.6, and making a request for internet access through browser it does not ask for authentication. There is no pop up window received for user name password to authenticate users.
Upon creating a group and then adding a few members (user1,user2,user3 etc.) to it, we configure rules to restrict user access to internet in the Global settings tab. After saving all the configuration and taking a restart of the proxy server, when we try to log on to internet from a
different client machine (browser) using an existing user id and password, it does not prompt us for user name and password even though the option "restrict access" in global setting is properly set.
My first question......
=>DOES iPlanet Web Proxy allow for such authentication pop up ??
=> If Yes, then kindly let us know where we have gone wrong in configuring the server.
We are NOT using any webserver or LDAP to authenticate users. No SSL is enabled.
Please suggest.

Is iPlanet Web Proxy Server support OpenLdap authentication ?

Do you know Is iPlanet Web Proxy Server support OpenLdap authentication ?

Hi
This as per the HTTP/1.1 RFC (RFC2616)
The Connection general-header field allows the sender to specify options that are desired for that particular connection and MUST NOT be communicated by proxies over further connections.
The Connection header has the following grammar:
Connection = "Connection" ":" 1#(connection-token)
connection-token = token
HTTP/1.1 proxies MUST parse the Connection header field before a message is forwarded and, for each connection-token in this field, remove any header field(s) from the message with the same name as the connection-token. Connection options are signaled by the presence of a connection-token in the Connection header field, not by any corresponding additional header field(s), since the additional header field may not be sent if there are no parameters associated with that connection option.
Read the following at
http://www.w3.org/Protocols/rfc2616/rfc2616-sec8.html#sec8.1.3
and
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.10

In iPlanet Web Proxy Server 3.6 on Win2000, how do I turn on authentication? I want to force users to enter an id and pw when they go thru the proxy to websites out on the net. Thanks

Mal,
You'll need to point to some user database, either the local db on Proxy or an ldap server. The ldap server is the best choice as the local db just stores users in a flat file and becomes unreliable after 1000 entries.
To enable authentication, manage the proxy server instance and navigate to Restrict Access.
From there, turn on access control, and click on the Permissions button. This will open up a new window to allow you to setup your access control rules and restrictions. When you're done, click on Done, apply your changes and restart the proxy server and you should be on your way.

Web Proxy Server Load Balancing

I deployed Sun Jave Web Proxy Server 4.0 as a Reverse Proxy. I would also like to use it as a load balancer. As per the instructions, I configured the obj.conf file as shown below
Route fn="set-origin-server" server="https://xx.xx.xx.xx" server="https:yy.yy.yy.yy" sticky-cookie="JSESSIONID" sticky-param="jsessionid" route-hdr="Proxy-jroute" route-cookie="JROUTE" rewrite-host="true" rewrite-location="true" rewrite-content-location="true"
But, it is not doing load balancing. It always sends to the first server (xx.xx.xx.xx). I guess that is because I used mapping as follows:
NameTrans fn="reverse-map" from="https:xx.xx.xx.xx" to="https://server.net" rewrite-location="true" rewrite-content-location="true"
NameTrans fn="redirect" from="http://server" url="https://xx.xx.xx.xx"
NameTrans fn="map" from="https://server" to="https://xx.xx.xx.xx" rewrite-host="true" name="pa-server-farm1" NameTrans fn="map" from="/" to="https://xx.xx.xx.xx" rewrite-host="true" name="pa-server-farm1"PathCheck fn="url-check"ObjectType fn="block-ip"
ObjectType fn="cache-enable" cache-auth="1" cache-https="1" query-maxlen="0" min-size="0" Service fn="proxy-retrieve"
I don't understand how routing and mapping work togother. Any help in this regard is appreciated.

Motor,
the following is from the Web Proxy Sever Administration guide. Please, check the last paragraph for the explanation. Any how, the problem is simple. I am using the Proxy Server as the Reverse proxy. And at the same time, I would like to use two origin servers (for load balancing) instead of one. How do I make both load balancing and reverse proxy functions work together?
Thanks
To Create Regular or Reverse Mapping
Access the Server Manager, and click the URLs tab.
Click the Create Mapping link.
The Create Mapping page is displayed.
In the page that appears, provide the source prefix and source destination for the regular mapping,
for example,
Source prefix: http://proxy.site.com
Source destination: http://http.site.com/
Click OK.
Return to the page and create the reverse mapping, for example,
Reverse mapping:
Source prefix: http://http.site.com/
Source destination: http://proxy.site.com/
To make the change, click OK.
Once you click the OK button, the proxy server adds one or more additional mappings. To see the mappings, click the lView/Edit Mappings link. Additional mappings would be in the following format:
from: /
to: http://http.site.com/
These additional automatic mappings are for users who connect to the reverse proxy as a normal server. The first mapping is to catch users connecting to the reverse proxy as a regular proxy. The �/� mapping is added only if the user doesn't change the contents of the Map Source Prefix text box provided automatically by the Administration GUI. Depending on the setup, usually the second mapping is the only one required, but the extra mapping does not cause problems in the proxy.

How would a corporation deploy Sun ONE Web Proxy Server?

A corporation should deploy Sun ONE Web Proxy Server at the following key places:
* The Internet gateway: Sun ONE Web Proxy Server deployed just behind the firewall facilitates access to the Internet and reduces response times and communications expense.
* Major sub-network connections: Marketing, Sales, Product Development, Human Resources, and Finance departments might have their own subnetworks. An Sun ONE Web Proxy Server deployed at each subnet can reduce traffic on the corporate backbone.
* Remote offices that are disconnected from the internal network: Sun ONE Web Proxy Server can provide a quick mechanism for replicating content when necessary, providing better company integration and increasing network performance without large capital and communications expense.
* Internationally: Outside the United States, communications bandwidth is typically much more expensive, making Sun ONE Web Proxy Servers even more cost effective. Every international office can make use of an Sun ONE Web Proxy Server.
* Outside the firewall as a Web server substitute in reverse proxy configuration: This protects information on the secure Web server behind the firewall and offers load balancing via caching.

Does Sun ONE Web Proxy Server have built-in log analysis tools? What kind o

Sun ONE Web Proxy Server automatically logs all requests using either the common log-file format or an extended log-file format. The extended log-file format includes the referrer field and user agent. You can also create your own log file format by selecting which HTTP fields you would like to log. A built-in log analysis program includes reports such as total number of requests, total bytes transfered, most commmon URLs requested, most common IP addresses making requests, performance during peak periods, cache hit rates, and estimated response time reduction. The items logged and the analysis program are completely configurable using the server manager's HTML form.

Sun Java System Web Server is a web server; it serves web pages to web clients. Sun Java System Web Proxy Server, on the other hand, is a web proxy server; it routes requests/responses between web servers and web clients.
You can configure Web Server to act as a simple reverse proxy by installing the Web Server 6.1 Reverse Proxy Plugin. This doesn't provide any of the forward proxy or caching proxy functionality found in Web Proxy Server.
Both Web Server 6.1 and Web Proxy Server 4.0 are supported on Solaris 10.

Your proxy instance should start. The error you are seeing should only be for the admin server. Add the location of where your jvm.so is located to the LD_LIBRARY_PATH. The jvm.so is located under the JDK directory.

IPlanet Sun ONE Web Proxy Server 3.6 SP6 terminating

I have a problem with my proxy server server.
I use iPlanet Sun ONE Web Proxy Server 3.6 SP6
It is terminating and the service is restarting. This happens about 10-15 times a day. The message I get from the log is :
[22/Mar/2005:09:29:30] info: server terminating... each time it terminates.
I know for sure that this is no hardware issue (as I have changed the hard disk recently). My OS is win2000 server SP4 + all released patches from MS.
Also I have reinstalled the OS several times (clean install after format) and I got the same result.
Also I tried to use the proxy with/without LDAP server for authentication - the same.
Any suggestions/recommendations are mostly welcome.
Thanks in advance,
Kaloyan

Dear Kaloyan,
Migration to another proxy (e.g. ISA) seems to be quickest solution for your problem, as WebProxy doesn't work well on w2k platform.

Routing problem with Web Proxy Server SP5 on AIX

I downloaded Sun Java System Web Proxy Server 3.6 Service Pack 5 and loaded it onto an AIX v4.3.3 server. Everything is configured correctly, and the server and admin functions start clean.
This server has two interfaces. One is an INSIDE interface that points toward our network. The other is an OUTSIDE interface pointed toward the Internet. When a user uses the proxy server, he queries the INSIDE interface at port 8080. At that point, the proxy server should contact the destination web address using the OUTSIDE interface on port 80. However,
a firewall log shows that the request that should be coming from the OUTSIDE is really originating from the INSIDE.
My routing table looks OK, but I wanted to prove it. So on the proxy server, at command line, I ran a ping and traceroute to www.sun.com. The firewall log showed that the attempts were correctly coming from the OUTSIDE interface. Yet, at my PC, I try to go to the www.sun.com from a browser, and the log shows that it is coming from the INSIDE.
Does anyone know why the port 80 relays are going out the wrong way?
Thanks to all in advance.
Bill

This also happens on Solaris. Suspect they are performing raw IP connections - and not paying particular attention to the server routing tables.

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.

Can XI /PI be configured with a web proxy for outbound communication.

We have a business to business scenario. There is a firewall and web dispatcher for inbound from the partner.
I want to know if the XI system can be configured with a web proxy for any communication that is outbound from the XI system to the partner (outside the company).
Your help will not only be appreciated, but also be rewarded.
Thanks.

2 cases for the configuration of HTTP Proxy:
1) If you use an adapter type running on the ABAP Stack (table PPROXY_C) and the RFC destination SAPHTTPA must to work.
Refere to this: Simple connection to a remote HTTP Server using Port, Server, Username & Pw
2) If you use adapter running in the Adapter Engine then you have to configure the proxy for the JAVA Stack:

Just started getting this message but don't know how to correct the problem: irefox is configured to use a proxy server that is refusing connections.

Firefox is configured to use a proxy server that is refusing connections.

#Click the big orange Firefox button, or open the Tools menu.
#Click Options.
#Go to Advanced.
#Go to Network.
#Under Connection, click Settings.
#Choose No proxy, or Use system settings.

AP Extreme (WiFi Access Point)... LAN... Web Proxy Server help.

Hello...
I need a little help configuring this Airport Extreme as a Wireless Access point, serving a bunch of iPads via the schools LAN connection for which traffic is routed through a Web Proxy Server. I've been told to set it up as a bridge as the PC LAN and Proxy are providing NAT but can't seem to crack it.
The WiFi side of things is up and running, we can all see and connect to the AP.
I'm told that it was working fine before the school break in the summer, then something was changed and the position of the AP altered.
The Web Proxy Server is normally accesses from the PC's via the following address... IP > 10.12.14.122 // PORT > 3128
I'm not certain where the Proxy settings need to go in the new 'simple' Airport Utility, can't see a place for Port at all?!?
(I've taken the AP home, tried it on my home network and it works fine, so we know its all OK and its down to config).
Here are some screen images of the settings as they are, that do not work.
(I was trying a few different settings hence the screens like Static/DHCP etc.)
Any help is greatly appreciated.

Hi Daniel,
>>Now when I go on a client site my internet access on the host laptop is via a web proxy on a LAN connection.
"LAN connection" means physical NIC (Realtek PCIe GBE Family Controller) ?
" web proxy " means adding a proxy server IP in IE ?
Bounding the NIC (Realtek PCIe ) to external virtual switch then connect all VMs to that external virtual switch ,still can not access ?
Best Regards
