  • Deploying play! 2.0 application on an apache server with a reverse proxy

    - by locrizak
    I'm trying to deploy my play! 2.0 application on an Ubuntu 11.10 server and I have been running into error after error and hope someone can help me here. I am try to deploy my Play! application using a reverse proxy on Apache 2. I have enabled the apache proxy modules and configured the proxy.conf file in mods_enabled. The vhost for my domain looks like this: <Directory /var/www/stage.domain.com AllowOverride None Order Deny,Allow Deny from all </Directory <VirtualHost *:80 DocumentRoot /var/www/stage.domain.com/web ServerName stage.domain.com ServerAdmin [email protected] # ProxyRequests Off # ProxyPreserveHost On <Proxy * Order allow,deny Allow from all </Proxy # ProxyVia On # ProxyPass /play/ http://localhost:9000/ # ProxyPassReverse /play/ http://localhost:9000/ ErrorLog /var/log/ispconfig/httpd/stage.domain.com/error.log ErrorDocument 400 /error/400.html ErrorDocument 401 /error/401.html ErrorDocument 403 /error/403.html ErrorDocument 404 /error/404.html ErrorDocument 405 /error/405.html ErrorDocument 500 /error/500.html ErrorDocument 502 /error/502.html ErrorDocument 503 /error/503.html <IfModule mod_ssl.c </IfModule <Directory /var/www/stage.domain.com/web Options FollowSymLinks AllowOverride All Order allow,deny Allow from all </Directory <Directory /var/www/clients/client2/web7/web Options FollowSymLinks AllowOverride All Order allow,deny Allow from all </Directory # Clear PHP settings of this website <FilesMatch "\.ph(p3?|tml)$" SetHandler None </FilesMatch # mod_php enabled AddType application/x-httpd-php .php .php3 .php4 .php5 php_admin_value sendmail_path "/usr/sbin/sendmail -t -i [email protected]" php_admin_value upload_tmp_dir /var/www/clients/client2/web7/tmp php_admin_value session.save_path /var/www/clients/client2/web7/tmp # PHPIniDir /var/www/conf/web7 php_admin_value open_basedir /var/www/clients/client2/web7/:/var/www/clients/client2/web7/web:/va$ # add support for apache mpm_itk <IfModule mpm_itk_module AssignUserId web7 client2 </IfModule <IfModule mod_dav_fs.c # Do not execute PHP files in webdav directory <Directory /var/www/clients/client2/web7/webdav <FilesMatch "\.ph(p3?|tml)$" SetHandler None </FilesMatch </Directory # DO NOT REMOVE THE COMMENTS! # IF YOU REMOVE THEM, WEBDAV WILL NOT WORK ANYMORE! # WEBDAV BEGIN # WEBDAV END </IfModule # <Location /play/ # ProxyPass http://localhost:9000/ # SetEnv force-proxy-request-1.0 1 # SetEnv proxy-nokeepalive 1 # </Location ProxyRequests Off ProxyPass /play/ http://localhost:9000/ ProxyPassReverse /play/ localhost:9000/ ProxyPass /play http://localhost:9000/ ProxyPassReverse /play http://localhost:9000/ # SetEnv force-proxy-request-1.0 1 # SetEnv proxy-nokeepalive 1 </VirtualHost This vhost file was generated by ispconfig and I have not touched anything that was there before just added onto. As you can see by the commented out parts I have tried a lot of different things based on random tutorials I have found but all of them have ended up in Internal Server Error, 503 and most often a '502 Bad Gateway`. I can start play and it does connect successfully to my database. I can get a page to show up when there is an error and the play! stack trace error pages comes up but where everything is fine I get one of the errors above. My application.conf file looks like this: db info ....... application.mode=PROD logger.root=ERROR # Logger used by the framework: logger.play=INFO # Logger provided to your application: logger.application=DEBUG http.path="/play/" XForwardedSupport="127.0.0.1" And my hosts file looks like this (I have never changed or added anything to the host file): 127.0.0.1 localhost 127.0.1.1 matrix # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters Any insights onto what I might be doing wrong or if theres anything I can try please let me know! Thanks!! Edit Again the reverse proxy will work (I checked with sending to to google.com). Its when there is a successful connection to Netty. It's like Netty refuses the connection to the page. Edit 2 output from apachectl -S _default_:8081 127.0.0.1 (/etc/apache2/sites-enabled/000-apps.vhost:10) *:8090 is a NameVirtualHost default server 127.0.0.1 (/etc/apache2/sites-enabled/000-ispconfig.vhost:10) port 8090 namevhost 127.0.0.1 (/etc/apache2/sites-enabled/000-ispconfig.vhost:10) *:80 is a NameVirtualHost default server 127.0.0.1 (/etc/apache2/sites-enabled/000-default:1) port 80 namevhost 127.0.0.1 (/etc/apache2/sites-enabled/000-default:1) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7) port 80 namevhost stage.domain.com (/etc/apache2/sites-enabled/100-stage.domain.com.vhost:7) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7)

  • Reverse-engineer SharePoint fields, content types and list instance—Part2

    - by ybbest
    Reverse-engineer SharePoint fields, content types and list instance—Part1 Reverse-engineer SharePoint fields, content types and list instance—Part2 In the part1 of this series, I demonstrated how to use VS2010 to Reverse-engineer SharePoint fields, content types and list instances. In the part 2 of this series, I will demonstrate how to do the same using CKS:Dev. CKS:Dev extends the Visual Studio 2010 SharePoint project system with advanced templates and tools. Using these extensions you will be able to find relevant information from your SharePoint environments without leaving Visual Studio. You will have greater productivity while developing SharePoint components and you will have greater deployment capabilities on your local SharePoint installation. You can download the complete solution here. 1. First, download and install appropriate CKS:Dev from CodePlex. If you are using SharePoint Foundation 2010 then download and install the SharePoint Foundation 2010 version If you are using SharePoint Server 2010 then download and install the SharePoint Server 2010 version 2. After installation, you need to restart your visual studio and create empty SharePoint. 3. Go to Viewà Server Explorer 4. Add SharePoint web application connection to the server explorer. 5. After add the connection, you can browse to see the contents for the Web Application. 6. Go to Site Columns à YBBEST (Custom Group of you own choice) and right-click the YBBEST Folder and Click Import Site Columns. 7. Go to ContentTypesà YBBEST (Custom Group of you own choice) and right-click the YBBEST Folder and Click Import Content Types. 8. After the import completes, you can find the fields and contentTypes in the SharePoint project below. Of course you need to do some modification to your current project to make it work. 9. Next, create list instances using list instance item template in Visual Studio 10. Finally, create lookup columns using the feature receivers and the final project will look like this. You can download the complete solution here.

  • configure Reverse DNS for VPS with amazon route 53, ISP or Amazon Route 53 issue?

    - by Oscar Cabrero
    i have a VPS hosted with myhosting.com, the domain is hosted in godaddy and the DNS records are managed in AMAZON route 53. i was told by myhosting support that i should create a PTR record on my DNS but i have read that in order to reverse DNS for an IP this record should be created in the ISP records wich sounds have sense. because if i want to get the domain name via an IP the request will never be forwarded to AMAZON instead it will ask the ISP for it am i rigth or MyHosting support is correct and i should setup PTR record on Amazon which i already did THANKS Oscar

  • Why does using nginx as a reverse proxy break local links?

    - by tsvallender
    I've just set up nginx as a reverse proxy, so some sites served from the box are served directly by it and others are forwarded to a Node.js server. The site being served by Node.js, however, is displayed with no CSS or images, so I assume the links are somehow being broken, but don't know why. The following is the only file in /etc/nginx/sites-enabled: server { listen 80; ## listen for ipv4 listen [::]:80 default ipv6only=on; ## listen for ipv6 server_name dev.my.site; access_log /var/log/nginx/localhost.access.log; location / { root /var/www; index index.html index.htm; } location /myNodeSite { proxy_pass http://127.0.0.1:8080/; proxy_redirect off; proxy_set_header Host $host; } } I had thought perhaps it was trying to find them in /var/www due to the first entry, but removing that doesn't seem to help.

  • sshd warning, "POSSIBLE BREAK-IN ATTEMPT!" for failed reverse DNS

    - by rking
    Whenever I SSH somewhere I get something like this in the logs: sshd[16734]: reverse mapping checking getaddrinfo for 1.2.3.4.crummyisp.net [1.2.3.4] failed - POSSIBLE BREAK-IN ATTEMPT! And it is right: if I do host 1.2.3.4 it returns 1.2.3.4.crummyisp.net, but if I do host 1.2.3.4.crummyisp.net it is not found. I have two questions: What security threat is there? How could anyone fake a one-way DNS in some threatening way? Do I have any recourse for fixing this? I'll send my ISP a bug report, but who knows where that'll go.

  • How do you cache web pages with a personalized header using caching reverse proxy such as Squid, Var

    - by Continuation
    Pretty much every page of my website is dynamically generated. However they don't change that frequently (kinda similar to a forum page). So I'd like to cache them using a caching reverse proxy such as Squid, varnish or Nginx. The problem is that for my logged-in users, each of them will see a personalized header saying "Welcome John Doe. Logout" on the upper right corner of the page (just like serverfault). While users who aren't logged in will see a header that says "Login" instead. So basically even though every user will see the same page in general, they all slightly different version due to that personalized header. Is there any way so that I can cache the "main" part of the page and serve it from cache while generate the personalized header dynamically for each individual user? This must be a very common problem. How is it solved in general?

  • ubuntu 12.04.3 - Reverse DNS issue - slow ping interval but normal ping value

    - by McArthor Lee
    i'm running ubuntu 12.04.3 x86 desktop in my corporation environment. I join the corp domain by Likewise open. But when I ping another pc, say hostname is pc-test, "ping pc-test" or "ping pc-test.domain.name" returns slow interval (about 5 seconds) but the ping value is below 1 ms. When I use "ping -n pc-test", everything works well. So I conclude this is about reverse DNS issue. how to fix this issue? many thanks! Edit: In my understanding, reverse DNS issue is related to DNS server or Wins server, not only an ubuntu issue, is this right? if I wanna fix this issue as much as possible on ubuntu but not on network servers, what to do?

  • Reverse rendering of Urdu fonts

    - by Syed Muhammad Umair
    I am working on a project that is based on Urdu language in Ubuntu platform. I'm using Python language and have almost achieved my task. The problem is that, the Urdu text is rendered in reverse order. For example, consider the word ??? (which means work) consisting of the three letters: ? , ? , and ? The output is rendered in reverse order as ??? consisting of the three letters: ?, ?, and ? When copying this text to Open Office or opening the generated XML file in Firefox, the generated result is absolutely desired. How can this problem be solved?

  • Reverse proxying only a specific URL

    - by Bart Silverstrim
    I have a web server at www.ourcompany.com running Apache2. Using the proxy modules, I am able to (for example) get 172.16.0.5, an internal IP device, to be accessed on www.ourcompany.com/device. The trouble is that anyone can play with or explore the device using strings sent to www.ourcompany.com/device/change/settings/here.html. I'd like the reverse proxy to only work for a specific URL; www.ourcompany.com/device/you/must/use/this while anything else will be rejected if requested. Is there a setting that can be used to do this, or is it a simple rewrite condition placed in the virtualhost for the site under sites-enabled? What is the simplest, most maintainable way to sanitize requests to the internal device through the reverse proxy? Running Apache2 on Ubuntu.

  • Calling a web service through a reverse proxy

    - by Ken
    I had a w/s that when I first read the WSDL in test, was http, but needed to be accessed from behind a reverse proxy with https.  Here are the steps: Change the app.config, <httpTransport> to <httpsTransport> Change the app.config and the url address in the <endpoint>to the reverse proxy address Add System.Net.ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };  to disable certificate validation.  This will validate all certificates (including invalid, expired or self-signed ones).

  • What are the right reverse PTR, domain keys, and SPF settings for two domains running the same appli

    - by James A. Rosen
    I just read Jeff Atwood's recent post on DNS configuration for email and decided to give it a go on my application. I have a web-app that runs on one server under two different IPs and domain names, on both HTTP and HTTPS for each: <VirtualHost *:80> ServerName foo.org ServerAlias www.foo.org ... </VirtualHost> <VirtualHost 1.2.3.4:443> ServerName foo.org ServerAlias www.foo.org </VirtualHost> <VirtualHost *:80> ServerName bar.org ServerAlias www.bar.org ... </VirtualHost> <VirtualHost 2.3.4.5:443> ServerName bar.org ServerAlias www.bar.org </VirtualHost> I'm using GMail as my SMTP server. Do I need the reverse PTR and SenderID records? If so, do I put the same ones on all of my records (foo.org, www.foo.org, bar.org, www.bar.org, ASPMX.L.GOOGLE.COM, ASPMX2.GOOGLEMAIL.COM, ..)? I'm pretty sure I want the domain-keys records, but I'm not sure which domains to attach them to. The Google mail servers? foo.org and bar.org? Everything?

  • Nginx as reverse proxy: how to properly configure gateway timeout?

    - by user1281376
    We have configured Nginx as a reverse proxy to an Apache server farm, but I'm running into trouble with the gateway timeouts. Our Goal in human readable form is: "Deliver a request within one second, but if it really takes longer, deliver anyway", which for me translates into "Try the first Apache server in upstream for max 500ms. If we get a timeout / an error, try the next one and so on until we finally succeed." Now our relevant configuration is this: location @proxy { proxy_pass http://apache$request_uri; proxy_connect_timeout 1s; proxy_read_timeout 2s; } [...] upstream apache { server 127.0.0.1:8001 max_fails=1 fail_timeout=10s; server 10.1.x.x:8001 max_fails=1 fail_timeout=10s backup; server 10.1.x.x:8001 max_fails=1 fail_timeout=10s backup; server 10.1.x.x:8001 max_fails=1 fail_timeout=10s backup; } The problem here is that nginx seems to misunderstand this as "Try to get a response from the whole upstream cluster within one second and deliver a 50X error if we don't - without any limit on how long to try any upstream server", which is obviously not what we had in mind. Is there any way to get nginx to do what we want?

  • Is there a solution that lets Node.js act as an HTTP reverse proxy?

    - by Igor Zinov'yev
    Our company has a project that right now uses nginx as a reverse proxy for serving static content and supporting comet connections. We use long polling connections to get rid of constant refresh requests and let users get updates immediately. Now, I know there is a lot of code already written for Node.js, but is there a solution that lets Node.js act as a reverse proxy for serving static content as nginx does? Or maybe there is a framework that allows to quickly develop such a layer using Node.js?

  • How to invalidate nginx reverse proxy cache in front of other nginx servers?

    - by Olivier Lance
    I'm running a Proxmox server on a single IP address, that will dispatch HTTP requests to containers depending on the requested host. I am using nginx on the Proxmox side to listen to HTTP requests and I am using the proxy_pass directive in my different server blocks to dispatch requests according to the server_name. My containers run on Ubuntu and are also running a nginx instance. I'm having troubles with caching on a particular website that is fully static: nginx keeps on serving me stale content after files updates, until I: Clear /var/cache/nginx/ and restart nginx or set proxy_cache off for this server and reload the config Here's the detail of my configuration: On the server (proxmox): /etc/nginx/nginx.conf: user www-data; worker_processes 8; pid /var/run/nginx.pid; events { worker_connections 768; # multi_accept on; use epoll; } http { ## # Basic Settings ## sendfile on; #tcp_nopush on; tcp_nodelay on; #keepalive_timeout 65; types_hash_max_size 2048; server_tokens off; # server_names_hash_bucket_size 64; # server_name_in_redirect off; include /etc/nginx/mime.types; default_type application/octet-stream; client_body_buffer_size 1k; client_max_body_size 8m; large_client_header_buffers 1 1K; ignore_invalid_headers on; client_body_timeout 5; client_header_timeout 5; keepalive_timeout 5 5; send_timeout 5; server_name_in_redirect off; ## # Logging Settings ## access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; ## # Gzip Settings ## gzip on; gzip_disable "MSIE [1-6]\.(?!.*SV1)"; gzip_vary on; gzip_proxied any; gzip_comp_level 6; # gzip_buffers 16 8k; gzip_http_version 1.1; gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; limit_conn_zone $binary_remote_addr zone=gulag:1m; limit_conn gulag 50; ## # Virtual Host Configs ## include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } /etc/nginx/conf.d/proxy.conf: proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_hide_header X-Powered-By; proxy_intercept_errors on; proxy_buffering on; proxy_cache_key "$scheme://$host$request_uri"; proxy_cache_path /var/cache/nginx levels=1:2 keys_zone=cache:10m inactive=7d max_size=700m; /etc/nginx/sites-available/my-domain.conf: server { listen 80; server_name .my-domain.com; access_log off; location / { proxy_pass http://my-domain.local:80/; proxy_cache cache; proxy_cache_valid 12h; expires 30d; proxy_cache_use_stale error timeout invalid_header updating; } } On the container (my-domain.local): nginx.conf: (everything is inside the main config file -- it's been done quickly...) user www-data; worker_processes 1; error_log logs/error.log; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; #tcp_nopush on; keepalive_timeout 65; gzip off; server { listen 80; server_name .my-domain.com; root /var/www; access_log logs/host.access.log; } } I've read many blog posts and answers before resolving to posting my own questions... most answers I can see suggest setting sendfile off; but that didn't work for me. I have tried many other things, double checked my settings and all seems fine. So I'm wondering whether I am not expecting nginx's cache to do something it's not meant to...? Basically, I thought that if one of my static files in my container was updated, the cache in my reverse proxy would be invalidated and my browser would get the new version of the file when it requests it... But I now have the sentiment I misunderstood many things. Of all things, I now wonder how nginx on the server can know about a file in the container has changed? I have seen a directive proxy_header_pass (or something alike), should I use this to let the nginx instance from the container somehow inform the one in Proxmox about updated files? Is this expectation just a dream, or can I do it with nginx on my current architecture?

  • Managing multiple reverse proxies for one virtual host in apache2

    - by Chris Betti
    I have many reverse proxies defined for my js-host VirtualHost, like so: /etc/apache2/sites-available/js-host <VirtualHost *:80> ServerName js-host.example.com [...] ProxyPreserveHost On ProxyPass /serviceA http://192.168.100.50/ ProxyPassReverse /serviceA http://192.168.100.50/ ProxyPass /serviceB http://192.168.100.51/ ProxyPassReverse /serviceB http://192.168.100.51/ [...] ProxyPass /serviceZ http://192.168.100.75/ ProxyPassReverse /serviceZ http://192.168.100.75/ </VirtualHost> The js-host site is acting as shared config for all of the reverse proxies. This works, but managing the proxies involves edits to the shared config, and an apache2 restart. Is there a way to manage individual proxies with a2ensite and a2dissite (or a better alternative)? My main objective is to isolate each proxy config as a separate file, and manage it via commands. First Attempt I tried making separate files with their own VirtualHost entries for each service: /etc/apache2/sites-available/js-host-serviceA <VirtualHost *:80> ServerName js-host.example.com [...] ProxyPass /serviceA http://192.168.100.50/ ProxyPassReverse /serviceA http://192.168.100.50/ </VirtualHost> /etc/apache2/sites-available/js-host-serviceB <VirtualHost *:80> ServerName js-host.example.com [...] ProxyPass /serviceB http://192.168.100.51/ ProxyPassReverse /serviceB http://192.168.100.51/ </VirtualHost> The problem with this is apache2 loads the first VirtualHost for a particular ServerName, and ignores the rest. They aren't "merged" somehow as I'd hoped.

  • ODI 11g - Scripting a Reverse Engineer

    - by David Allan
    A common question is related to how to script the reverse engineer using the ODI SDK. This follows on from some of my posts on scripting in general and accelerated model and topology setup. Check out this viewlet here to see how to define a reverse engineering process using ODI's package. Using the ODI SDK, you can script this up using the OdiPackage and StepOdiCommand classes as follows;  OdiPackage pkg = new OdiPackage(folder, "Pkg_Rev"+modName);   StepOdiCommand step1 = new StepOdiCommand(pkg,"step1_cmd_reset");   step1.setCommandExpression(new Expression("OdiReverseResetTable \"-MODEL="+mod.getModelId()+"\"",null, Expression.SqlGroupType.NONE));   StepOdiCommand step2 = new StepOdiCommand(pkg,"step2_cmd_reset");   step2.setCommandExpression(new Expression("OdiReverseGetMetaData \"-MODEL="+mod.getModelId()+"\"",null, Expression.SqlGroupType.NONE));   StepOdiCommand step3 = new StepOdiCommand(pkg,"step3_cmd_reset");   step3.setCommandExpression(new Expression("OdiReverseSetMetaData \"-MODEL="+mod.getModelId()+"\"",null, Expression.SqlGroupType.NONE));   pkg.setFirstStep(step1);   step1.setNextStepAfterSuccess(step2);   step2.setNextStepAfterSuccess(step3); The biggest leap of faith for users is getting to know which SDK classes have to be used to build the objects in the design, using StepOdiCommand isn't necessarily obvious, once you see it in action though it is very simple to use. The above snippet uses an OdiModel variable named mod, its a snippet I added to the accelerated model creation script in the post linked above.

  • Refactoring this code that produces a reverse-lookup hash from another hash

    - by Frank Joseph Mattia
    This code is based on the idea of a Form Object http://blog.codeclimate.com/blog/2012/10/17/7-ways-to-decompose-fat-activerecord-models/ (see #3 if unfamiliar with the concept). My actual code in question may be found here: https://gist.github.com/frankjmattia/82a9945f30bde29eba88 The code takes a hash of objects/attributes and creates a reverse lookup hash to keep track of their delegations to do this. delegate :first_name, :email, to: :user, prefix: true But I am manually creating the delegations from a hash like this: DELEGATIONS = { user: [ :first_name, :email ] } At runtime when I want to look up the translated attribute names for the objects, all I have to go on are the delegated/prefixed (have to use a prefix to avoid naming collisions) attribute names like :user_first_name which aren't in sync with the rails i18n way of doing it: en: activerecord: attributes: user: email: 'Email Address' The code I have take the above delegations hash and turns it into a lookup table so when I override human_attribute_name I can get back the original attribute name and its class. Then I send #human_attribute_name to the original class with the original attribute name as its argument. The code I've come up with works but it is ugly to say the least. I've never really used #inject so this was a crash course for me and am quite unsure if this code effective way of solving my problem. Could someone recommend a simpler solution that does not require a reverse lookup table or does that seem like the right way to go? Thanks, - FJM

  • multiple godaddy domains to home router then reverse proxy to multiple internal servers [closed]

    - by Dan
    I need someone to steer me correctly... advising on all required components. I have multiple domains with godaddy, say site1.com , site2.com, site3.net I have multiple home LAMP servers... one on say, lampsrv1 = 192.168.0.2:8080 (windows) and lampsrv2 = 192.168.0.3:9080 (linux srv2) I would like to have server1.site1.com point to lampsrv1 and server2.site1.com point to lampsrv2 . I may also want server1.site2.com also point to my lampsrv1 as an option. My thinking is - I have a dedicated linux srv1 with a reverse proxy server behind the router, ie Apache or NGINX or equivalent directing to appropriate LAMP server. It's the godaddy subdomains, cnames or redirections, etc I'm having a challenge with for starters... I have tested apache with virtual servers but can't get proxying to work based on host header info... seems to go to one address making me think its actually the apache reverse proxying that's not quite working. Finally to add to this, my router has a dynamic IP but does lease for quite a while but that would be my final piece. So, I'm sure this might be a popular question but can't seem to piece this together. I need someone who has actually configured this scenario to advise but will take other suggestions.... please indicate if you have successfully configured this.
