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.
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.
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. Regards 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.
