Noodle verifies redirects it sends to your browser.
If you are accessing Noodle through one IP/domain this will not effect you.
If you use multiple IP/domains via NAT etc you will need one of 3 solutions:

  1. Add the IP/domains to the hosts file
  2. Add the IP/domains to your DNS (as A/CNAME and PTR) pointing to the Noodle server
  3. Add the following to noodle.properties: URLOverride = "https://noodle.domain.tld , or just: URLOverride = "/"

Be sure to update the "URL for Noodle" in the settings so that links in emails will resolve properly.
If you use multiple IPs without a domain name links in emails can not be expected to work reliably.
If you use multiple IPs on the same server you must bind to one of them.

Safari (GET/POST) requests sometimes block other requests.
In order to keep Noodle responsive we have disabled the instant features of Noodle on Safari.
We don't recommend using Safari; we do recommend Chrome, Firefox, and Internet Explorer.

If the Noodle log contains something like this:

2012.01.24 13:48:51: .intranet,ALERT: ConnectionAllocator: failed to allocate a new connection

SQL to list all error codes for your MSSQL version:

SELECT error,description FROM sysmessages where msglangid='1033' order by error;

All quiz answers should be quite short (no setup or output, many assumptions)

  1. In IE with JavaScript get an xml object (as sent from the server) from an iframe
  2. Dynamically call a java Class and method from within java
  3. List the values of a column that have a 2nd column who's value is not in any other row with SQL
  4. From a POISX CLI in one line individually compress all iso files in all sub directories using no loops and with the date inserted into the filenames
  5. Output a Git histoy from the beginning of the year in the format "graph tab date tab message"

For each question:

1 point for doing something logical
1 point for understanding/answering the question asked
1 point for getting a working answer
1 bonus point for being concise or explaining why the question/answer is useful

If your server has more than one (non lo) IP you will need to bind Noodle to one of them for the license key to work.
Add the address to the connection In server.xml

Restart the service for changes to take effect.

•

Clearing the DNS cache on your computer:
windows:

ipconfig /flushdns

OS X:

dscacheutil -flushcache

linux:

/etc/init.d/nscd restart

You can't clear the cache on your ISPs DNS servers but you can use different servers (opendns, googledns, etc)

Noodle works with PostgreSQL and uses the contributions which are included in the windows installer but installed separately with package management systems like apt and yum.

before PGSQL-v9 will need:

CREATE LANGUAGE plpgsql;

All versions need a user, database and rights and the following to load the lo-manage triggers (the Noodle installer for Windows will do this for you):

ALTER USER noodleuser WITH SUPERUSER;

You will need these SQLs if you are upgrading from an old version.

Noodle uses 4 things on the server

  1. The Noodle folder (older versions are named IntraNet)
  2. The database folders (can be on a different server)
  3. The Java Folder
  4. Optional tools; ffmpeg, anything used by custom search filters, etc

On Windows the Noodle folder is in %PROGRAMFILES(x86)% by default.

On Linux the Noodle folder is in /opt/ by default.

Among other things the Noodle folder contains the following of potential interest:

  1. conf/server.xml (connection settings)
  2. conf/noodle.properties (application settings)
  3. logs
  4. optional files like MOTD.html/custom.js/noodle.jks

You need custom scripts enabled.

var doc=top.noodle.headWindow().document;
var el=doc.getElementById("helpLink");
el.style.fontSize="";
el=doc.getElementById("feedback");
el.style.fontSize="";
el=doc.getElementById("logout");
el.style.fontSize="";
el=doc.getElementById("logout").parentNode.parentNode;
el.style.fontSize="14px";
