Nothing in Iptables on Ubuntu 13.04

[wyaeld]

I've tried getting this to work on my machine, and not having any luck getting it to work. No errors or issues came up.

However running sudo iptables --list shows nothing. My expectation is that I would see prax's rules to redirect the :80 and :433 to its own ports.

running http://myapp.dev/ fails to resolve in either Chrome or FF.

Any ideas where I'm going wrong?

This command doesn't output all the tables, the rules are stored in the nat table, what about: sudo iptables -L -t nat

[wyaeld]

$ sudo iptables -t nat -L -n -v

Does this look correct? I can see what looks like the expected redirects, but again Prax doesn't work. It could be corporate network proxies getting in the way, but I moved prax up in the resolve.conf to before dns and it didn't change anything

Dumb questions:

• is prax started?
• what does "getent hosts myapp.dev" say in CLI (it should point to localhost)?
• check your app's log:

$ cd path/to/myapp
$ prax log -f

$ bin/prax start
Starting prax in the background.

$ getent hosts

127.0.1.1       brad-datacom
127.0.0.1       ip6-localhost ip6-loopback

$ getent hosts doc_genie.dev
::1             doc_genie.dev

$ bin/prax list
doc_genie  ~/rails_projects/doc_genie
docgenie   ~/rails_projects/doc_genie

does that help?

[ysbaddaden]

I meant to check that getent is capable to resolve .dev domains to localhost, for instance:

$ getent hosts docgenie.dev
::1             docgenie.dev

You may start Prax in debug mode, then use cURL in another terminal to check:

$ PRAX_DEBUG=1 prax start --foreground
D, [2013-11-06T14:30:08.571769 #19682] DEBUG -- : Starting HTTP server on port 20559

I, [2013-11-06T14:30:16.271132 #19682]  INFO -- : Starting app docgenie (path/to/doc_genie)

curl -vv http://docgenie.dev/
[... expected HTML ...]

You may also want to check your app's log (maybe there was an error starting your app):

$ cd ~/rails_projects/doc_genie/
$ prax log
[... log of doc_genie app ...]

The log is also in ~/.prax/_logs/doc_genie.log
