Printing Issue from ITS with a Reverse Proxy Configured

Hi experts,
We have an enterprise portal landscape which can be accessed from the internet. The URLs are mapped using apache server as a reverse proxy. Also, we have configured the reverse proxy settings for accessing R/3 systems.
When the users try to take the print out from the ITS Web GUI accessed through the enterprise portal, the page redirects itself to an only internally resolvable host name of the R/3 ITS.
Due to this issue, users are not able to take prints from internet.
I would like to know if there is any way by which i can change this to my externally resolvable reverse proxy host address, which in turn can be mapped internally to the original host name at the reverse proxy level.
Can any one help me out in this?
Thanks a lot

Hi Shobin,

Help with Apache Reverse Proxy configuration with SAP Portal and SAP Webgui

Dear Experts,
I have an issue configuring Apache to work with SAP Portal and ERP webgui. Accessing Portal through Reverse Proxy is working fine. But the problem arises when we try to open an iView ERP webgui transaction page from Portal with the Reverse Proxy. Have anyone implemented similar requirements and could advice on the configuration required on the Apache side? Thank you

How to configure SharePoint HNSC with a reverse proxy server so that HNSC Share Point URLs are not exposed to end users.

Could you please let me know how SharePoint HNSC can be configured with a reverse proxy server so that HNSC Share Point URLs are not exposed to end users.
In normal path based site collections/web applications, reverse proxy configuration can be done using alternate access mappings with Public URL = "proxy URL", internal = "HNSC Share Point URL" so that share point sends response back
to Public URL = "proxy URL".
In Host Named Site Collections, alternate access mappings are not supported. Each HNSC is designed to have only one URL in each zone. Zone is one of the five zones(Default,Intranet,Internet,Custom,Extranet) with each of which only one alternate
URL is associated. This is what we are able to get using power shell command "Set-SPSiteUrl", but this will not help us to get the response back to proxy URL after a request sent to share point because we could not find any mechanism in share
point HNSC to respond to a different URL(proxy URL). Consequently, Share Point URLs are exposed to external users.
Below share point article in MSDN blog is symmetrical to what we are observing with Share Point 2013 and Proxy Server. It mentions that internal HNSC URLs can’t be hidden using any proxy server. If hiding the internal Share Point URLS is a requirement,
it suggests to use a web application instead of host named site collections.
Though I’m also observing the same behavior with Share Point 2013 HNSC, Could you please confirm my understanding is correct.
http://blogs.msdn.com/b/kaevans/archive/2012/03/27/what-every-sharepoint-admin-needs-to-know-about-host-named-site-collections.aspx
Excerpt from above article-
"Host Named Site Collections Only Use One Host Name
Continuing on the discussion on AAMs and host named site collections, you cannot use multiple host names to address a site collection in SharePoint 2010. Because host-named site collections have a single URL, they do not support alternate access mappings and
are always considered to be in the Default zone. This is important if you are using a reverse proxy to provide access to external users. Products like Unified Access Gateway 2010 allow external users to authenticate to your gateway and access a site
as http://uag.sharepoint.com and forward the call to http://portal.sharepoint.com. Remember that URL rewriting is not permitted. Further, a site collection can only respond to one host name. This means if you are using a reverse proxy, it must forward the
calls to the same URL. If your networking team has a policy against exposing internal URLs externally, you must instead use web applications and extend the web application using an alternate access mapping."<u5:p></u5:p>

Hi Satish,
You are right that only one URL is allowed for each zone of the host-name site collections in both SharePoint 2010 and SharePoint 2013.
It is by design that each host-name site collection only support one URL for each zone.
The article below is about RTM version of SharePoint, and it is the same for SharePoint 2013 with the latest CU.
https://support.microsoft.com/en-us/kb/2826457
So to make the URL of HNSC not exposed to external users is not supported, you need to use path-based sites instead.
Best regards.
Thanks

Save/Print document from DMS with Office 365

Dear All,
We are on ECC 6.0 EHP 4 of SAP. When a word document attachment is opened in DMS (CV03N) from a PC having locally installed Office 365. The document is opening up in office 365 interface inside SAP. Which is good, but we are unable to save the document on to local PC. Upon clicking the File menu, i suppose word tries to bring an additional view instead of a drop down, which was the case with earlier versions. I think this is causing the problem. Can any one suggest how to save and print documents from DMS with locally installed Office 365.?
We have figured out a work around to bring up the 'Save As' and 'Print' functionalities on to quick access tool bar. Using these shortcuts we are able to save the document but not print.
Thank you.
Regards,
Kartik

Dear Ms. Mohanapriya,
We are quite happy with the existing DMS and our intention is not to change the existing architecture. Well, now we are able to open the document and have a workaround to save to local PC. And once the document is saved to PC users are able to print.
Now we are looking for a solution to enable file menu of Office 365 within OLE container of SAP.

Print postcards from 'Pages' with a Lexmark C544dn printer?

I have been trying, unsuccessfully, to print postcards from 'Pages' with a Lexmark C544dn printer. As far as I can say, I have correctly set all parameters, but the output is always blank. Any ideas? FYI Lexmark have been unable to help!!

GeoffBob wrote:
Hi Jerry, and thanks for your response.
What I want to achieve is a landscape postcard with one line of text across the top. I use this to stick on a few sticky notes for training workshop participants to use, to record their special interests for the session. I have done this for years with a Windows PC, MS Word and an HP4500dn LaserJet, and assumed that it would be a simple process with the new set-up (iMac, OS-X 10.7.4, iWork Pages 4.1 and Lexmark C544dn).
I started a blank document, with the paper size set to 6 x 4 inches landscape format. I re-set the margins to suit the size of the postcard, so that the text appeared to be in the right position, on screen.
I used the MP tray to feed the paper (there is only this one input, apart from the regular paper tray), and have tried this at the left side, in the centre and at the right side, in both landscape and portrait format.
I have even tried putting a sheet of portrait A4 paper through, and the printing shows up two thirds towards the bottom of the sheet, across the narrow dimension of the sheet. This makes me think that the machine is 'printing' after the paper has passed through.
Any idea what I am missing? Thanks, Geoff
Your trial with a full size paper tells the story, I think. Your ink is missing the post card. Try again with a small card. After initiating the Print function, make sure you are seeing the expanded Print dialog with the preview on the left side of the dialog window. Does everything look OK there? Paper correct size and orientation? Text showing where it should in the preview?

Reverse Proxy Configuration - Apache as an SSL reverse-proxy

Hi,
We have EP 6.0 SP 14 installed with SSL configured.
We are in need to open the application to internet.
For the same we have set up a reverse proxy server (Apache as SSL
Reverse Proxy).
Our requirement is to open the application to the internet with
web address https://abc.domain.com.
The issue is we are able to access the application from internet only when
https://abc.domain.com/irj/potal is typed.
(ie.) Mapping is working fine for
https://abc.domain.com/irj/portal to
our EP Portal address https://abc2.domain.com:50001/irj/portal
And not working for mapping https://abc.domain.com to our EP Portal
address https://abc2.domain.com:50001/irj/portal
We have been working on to resolve this issue for days together but have been really unsuccessful
Kindly help us in resolving the same asap.
Note : The references we used are:

Thanks much for the feedback. We're using the default settings on the HTTP rule we have set up for the portal on the ISA server. We'll be looking into the details of what the default rule settings are, however we did find a note in the Microsoft Knowledge base detailing with the ISA server screening high bits in URL strings for Outlook Web Access (OWA). This generates a similar error message. Here is the link to the detailed note on the Microsoft web site:
http://support.microsoft.com/?scid=kb;en-us;837865
Also,we are going to be applying the SP1 upgrade to the ISA server (released in March) to see if this might be some type of issue that may have been identified and corrected by the service pack. We'll see what happens with that.
One area where we can recreate the problem at will is when we set up the system landscape configuration. We can navigate to a system configuration object, however when we attempt to right click to edit the object we get the error. There are other circumstances where we get errors but that is one that occurs for sure. Anyone have any idea as to what might be special about that type of transaction??
Thanks again.

Forward parameters in reverse proxy configuration

Hi,
Looking at the detailed configuration in a reverse proxy rule in SJSWS, I have derived the following conclusions:
1) Where the SJSWS listener has SSL-enabled, reverse proxy works on a HTTPS in, HTTP out basis.
2) Details in the incoming request's SSL header, such as User DN, will be stripped out and remapped into the outgoing request as a custom header, e.g. "Proxy-user-dn".
Can anybody tell me if I have gotten anything wrong above?
We are currently switching over from an Apache/mod_proxy/mod_ssl --> Apache/mod_jk --> Apache Tomcat server setup to a hybrid model where SJSWS is the web server reverse proxying to Tomcat (old apps) and SJSAS (new apps).
My question:
All our apps use the User DN string as the user ID. Previously, we developed a custom module in Apache to read the DN at the Apache level and then rewrite it into the Basic Auth user name header in the outgoing request. The Tomcat webapp will then authenticate the user based on the Basic Auth user name property. Is it possible for me to remap it into something similar here in the SJSWS reverse proxy configuration?
Thanks!
Wong

I am not a reverse proxy expert, but this Object-type SAF should forward userdn
http://docs.sun.com/app/docs/doc/820-1062/6ncoqnq3b?l=en&a=view&q=forward-user-dn
You can look for more such SAFs in this document.

Problem with Apache reverse proxy after applying SP13 NW

Hello,
we have a NW04 EP Portal and a Apache reverse proxy in the DMZ. After applying SP 13 for the portal we get the following error from the reverse proxy:
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /irj/.
Reason: Error reading from remote server

Load balance with a reverse proxy in front

I have a CSS11501 load balancing 2 web servers. We want to use an Aventail in front of it as a reverse proxy, to control access to these servers. How can I ensure that the two servers will be load balanced, and make sure that an end user always hits the same server during his session since the client will always be the Aventail? thanks in advance

Is your proxy spoofing client ip address ?
If yes, nothing special needs to be done.
If not, the problem is to sticky client to the same server.
We can't use sticky srcip because all traffic comes from a single ip.
The only solution is to use cookies.
You can use arrowpoint cookies.
You can find a sample config at :

Cannot print coupons from SmartSource with FireFox 3.6.14

I was just upgraded to Firefox 3.6.14 and suddenly I cannot print coupons from SmartSource. I keep getting the message that Java is disabled but it is not. I uninstalled Java and reinstalled it and still get the problem. I can successfully print from Internet Explorer.
I've never had a problem with this until the 3.6.14 upgrade. On the Java web site, it said if you're getting an error message and you recently upgraded Firefox, download an update so I did that too. No help. I've restarted Firefox after each change.

There's a Bug in 3.6.14 with Java. A quick patch is being tested for a 3.6.15 release, but no date is set for that release. Probably early next week.

The solution for this problema was put the proxy server name and IP in the database hosts.
In Oracle portal it's essencial that database could resolve the name of all componentes, like portal mid-tier, web cache, sso, proxy server, etc.

Trouble with Basic Reverse Proxy to an IIS machine

Hi All,
          I am a bit new at this, so bear with me. I am attempting to use Weblogic 8.1 SP3 as a Reverse Proxy to an IIS server. I have configured the HttpProxyServlet and it is the default servlet in my server.
          The kicker here is that it works to google.com or cnn.com, but it fails with a 404 to my internal IIS server. Could IIS be doing something to prevent this?
          My web.xml looks like this:
          <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">

Yes, you are able to do this using IIS.
          have you checked the settings on your IIS Server?
          also i notice in your proxy servlet that you don't have url mapping for web page extensions? Will this affect it?
          <servlet-mapping>
          <servlet-name>ProxyServlet</servlet-name>

Goods Issue from ECP with Batch Management

Hi experts,
I would like to make a Goods Issue from Execution Services in Easy Cost Planning. But the material has Batch Management active and I am not able to inform the batch.
I know I can make the same movement from MB1B but I would like to do it from the Easy Cost Planning environment.
Is it possible?

Dear,
I think you can solve this through your Characteristics in the Costing Model. In the Characteristic Edit Screen, Goto Values tab, Select your material and click on Object Dependecies Button, see if you can use or create a new Dependency for your material for picking or suggesting batch number.
Hope this helps...

SAPUI5 app and Reverse proxy configuration

Hi
Im trying to configure proxyserver for Cross origin resource sharing issue.
The below steps i have configured in my machine.
1. I have developed an application which consumes data through odata.
2. Download and configured Apache server and enabled proxy module as per this url
http://scn.sap.com/community/developer-center/front-end/blog/2013/06/29/solving-same-origin-policy-issue-in-different-ways
3. In httpd.config file added the below reverse proxy setup
ProxyPass /poodata http://HOSTNAME:8000/sap/opu/odata/sap/Z_PORDER_SRV/
ProxyPassReverse /poodata http://HOSTNAME:8000/sap/opu/odata/sap/Z_PORDER_SRV/
4. Changed my service url as
var serviceUrl = "proxy/http/localhost/poodata";
5. Also i have added java-property-utils-1.9.jar and cors-filter-1.8.jar then
in web.xml i have added Eventhough its seems not neccessary.
<filter>
<display-name>CacheControlFilter</display-name>
<filter-name>CacheControlFilter</filter-name>
<filter-class>com.sap.ui5.resource.CacheControlFilter</filter-class>
</filter>
<filter>
<filter-name>CORS</filter-name>
<filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class>
</filter>
6. Finally when i am executing the application throgh http://localhost:9080/SamplePO/ Its working. But Instead of localhost when im using IP address it shows NO DATA and throws the "500 internal server error - only allowed for local testing"
also the application is trying to fetch data from 'http://10.130.41.158:9080/SamplePO/proxy/http/localhost/poodata/$metadata' where the location should be 'http/localhost/poodata/$metadata'.
I want to access this application in my iPAD through WIFI by passing IP address followed by application name (http://10.130.41.158:9080/SamplePO).
Please help me to fix this issue.
