This is a story about developing and using a system to manage 10000 wifi routers used by
The Cloud - http://www.thecloud.co.uk/

Essential logic that enabled us to do it was that of Unix: many small tools and processees
working together in asynchronous manner eg not depending on each other to perform
the tasks that each component was built to do. Other than Perl, it was an extensive use
of shell scripts (including grep/awk/sed/cut) and filesystem that was key.

Each of these routers was connecting into the core network on an ADSL line, with PPP,
inside few LT2P tunnels which contained all the sessions. Core routers were 7200 class
Cisco. Edge routers were mostly Ericsson and Speedtouch, with later addition of Cisco
and other vendors for more sophisticated edge applications and protocols.

FreeRADIUS was another key component. Mechanism we used to capture events which would
enable us to manage routers was via radius proxy (see RFC 2865 Proxy-State). We transparently
intercepted radius accounting packets and created an event from each PPP login from the edge
into the core. These events were then stored locally on radius proxy servers as XML files, using
our own implementation of maildir (http://cr.yp.to/proto/maildir.html), written as a Perl Library.

Events were delivered to servers which managed routers using Beep protocol.

Notes on next componet in the system coming soon ...

Back: How do I find my way around?

Here are some more advanced workspace navigation techniques. If you like, you can go back to the basic page, called How do I find my way around?

You can use tags to group pages that are related. Anyone can put a tag on a page by clicking the Add tag button in the sidebar. You can find pages with a given tag by clicking the tag if it appears in the sidebar, or by going to the dashboard, then clicking on the "All tags" link.

Next: Can I change something?

Back: What's the funny punctuation?

Making links in Socialtext is very simple.

To add a link to a page in the workspace, first double-click to enter editing mode. Alternatively, click the Edit button.

Type the name of the page you want to link to, and turn it into a link simply by selecting it and clicking on in the toolbar.

If you make a link to a page that doesn't exist yet, your link will appear with a dotted underline. When you click on the link, the page will be created.

How do I make a new page?

Up: Workspace Tour - Table of Contents
Back: How do I make links?

Visit the dashboard and click on the New Page Button. You will see a new page to edit. Change the name of the page by editing the title in the field on top. Put the text of the page in the larger space below. Click the green Save button.

You can also create a new page by making a link on an existing page. While editing, select the text to link and click on in the toolbar. You can also put the name of the page you wish to create in square brackets, like this: [Title of New Page].

After saving, the link will appear with a dashed underline, which means the link refers to page that does not exist. Whenever you click on a dashed link, you can create the missing page.

To practice, try making a new page with your name as a title using either method.

Congratulations! You know how to use a workspace
