hi i am new to Alfresco,I tried to walk my way through the WCM-Tutorial, but got stuck on page 20.
When I click on preview of index.jsp i am facing the following error on my browser.

Unable to connect
Firefox can't establish a connection to the server at www-alfresco-www–bob.avm.127-0-0-1.ip.alfrescodemo.net:8180.

Hi, I`m not sure but I think your problem is that you must start the alfresco Virtualization Sever and then it must work.
I think so and I hope that I can help you so.

Sirclueless,

    Good clue!

imemyself,

   Also, be sure to read the docs within
    $VIRTUAL_TOMCAT_HOME/conf/alfresco-virtserver.properties

Alsp please make sure that the hostname resolves to correct IP address by adding something like below to your hosts file

www-alfresco-www–bob.avm.127-0-0-1.ip.alfrescodemo.net 127.0.0.1

Pranshu & imemyself,

There is no need to alter your 'hosts' file in any way at all.
Only in the very earliest pre-pre-pre-release version of Alfresso
was this ever necessary (even then, it was just a quick hack to
demonstrate a "proof of concept" and nothing more).

Wildcard-DNS name resolution is now handled in a very scalable way;
I strongly suggest upgrading your server to a supported release.

To configure the virtualization server properly, see:

Hi Jcox,
Agree with you about that - if we configure proper name server and make client machine point to that, there is no need for hosts file.
For a developer who just want to do a temporary but entire configuration on their laptops - and work behind firewalls and proxies - possibly hosts file is an easier way - but with the addition pain of having to add a hosts file entry per .

Is it possible to change the preview URL from

admin.www-alfresco-www–bob.avm.127-0-0-1.ip.alfrescodemo.net:8180
to something like

admin.pranshu.com:8180

update -
I think the link you posted already answers the above question so please ignore.

Pranshu,

If you want to work on a machine with no access to the internet
(thus precluding using  XXX-XXX-XXX-XXX.ip.alfrescodemo.net
as your virtualization domain),  then you should set up your own
name server (or reconfigure your existing one)  so that it  includes
a wildcard domain for virtualization.  If you rely on a hack like
editing /etc/hosts with some pain you'll be able to set things up
for a static set of users & staging areas, but reviewers will *never*
be able to preview content that comes to them via a workflow.
This is because workflows use ephemeral AVM stores with
ephemeral DNS names – it's an ever-changing set of GUIDs.
Unfortunately, there's no way to create a DNS wildcard in  the
"hosts" file… you must use a nameserver (e.g.: Djbdns,  or BIND).

As mentioned in:
http://wiki.alfresco.com/wiki/Configuring_the_Virtualization_Server
you can configure BIND on windows or UNIX to create a wildcard
DNS domain for virtualization.   If you're on a UNIX platform,
you have at least two free/common options:   BIND and Djbdns.

My own preference on UNIX is to use Djbdns (tinydns + dnscache)
because it's more secure, stable, better designed, and elegant.
A fresh set of horrible security issues are discovered with each
new release of BIND, but not a single security flaw has been
seen in Djbdns for the past few years – despite a $500 reward.

If you go with Djbdns, be warned that the docs are only so-so,
and the config  may strike you as a little strange at first
(Daniel Bernstein has a different approach to daemons than
most folks in the world of UNIX).  It may take you a day or two
in order to feel like you've got the whole thing under your belt. 

There's no denying one thing:  DJB's programs are well thought-through
and executed with a level of care that has won him a devoted following.
If you try it, I think you'll like it.
