Viewing Rails from non-localhost using WEBrick server

During development, I'd like to see my Rails app from a computer other than localhost on a Linux system and also want to change the default port#. I thought this would do it:

Linux server: $ script/server -b 10.4.1.84 -p 5432 => Booting WEBrick... => Rails application started on http://10.4.1.84:5432 => Ctrl-C to shutdown; call with --help for options ...

Windows browser URL: http://10.4.1.84:5432/

BUT, the browser can't find this and the WEBrick server on Linux shows no activity.

Anyone know what gives?

Did you open that port (5432) under iptables?

Don't know for sure but I'll check. I'm primarily a Windows developer, just starting to move initial development over to Linux. The sys admin gave me the port #.

(I'm in-between systems at the moment which is why I wanted to view the app from my Windows system.)

btw, SHOULD the script work?

To test open up lynx or some other console based web browser from the Linux command line and point it to http://localhost:5432/ if that works then it's most likely iptables.

--R

then it's most likely iptables.

Yes. Thanks for the help.

I dunno if this helps but I added another domain in /etc/hosts.

127.0.0.1 localhost 127.0.1.1 [other mock domain name]

This indeed works great for testing two domains. Or at least it appears. request.domain is correct [and different] for both.

This one had me stumped for a while too but I have found if you modify Webrick config.rb and change the entry :DoNotReverseLookup => 'nil,' to 'true,' your non-local host will be able to connect with the Webrick server.

You can find the config.rb file for Rails 1.9.1 and 1.9.2 in this directory .../usr/lib/ruby/1.9.1/webrick/config.rb

Then the sysadmin needs a cluebat to the head. 5432 is the standard port for PostgreSQL and probably shouldn't be used for other purposes...

I'm not sure if you need the -b.

Best,
