Domain name fails when I'm offline

[dynaum]

When there is no internet connection the domain name of azk apps fail to respond.

@dynaum,

Unfortunately, this is an issue related with OS X, since it ignores /etc/resolver when disconnected.

The same issue occurs in http://pow.cx/ and is discussed in #104. The troubleshooting Can't access hosts while offline on OS X purposes the following solution:

This is due to a bug in the OS X resolver system. As a workaround, you can create an Ad-Hoc Wifi Network or add the hosts to your /etc/hosts file (perhaps with powder). See the discussion about this issue.

We're trying to figure out an alternative solution, but this is a kind of complex problem and we want to solve it in an elegant way, so it shouldn't be available so soon.

for now this solution is working for me:

$ brew install dnsmasq
# Create dnsmasq configuration file (using sample)
$ cp "$(brew --prefix dnsmasq)"/dnsmasq.conf.example /usr/local/etc/dnsmasq.conf
# add dnsmasq to startup
$ sudo cp -fv "$(brew --prefix dnsmasq)"/*.plist /Library/LaunchDaemons
$ sudo chown root /Library/LaunchDaemons/homebrew.mxcl.dnsmasq.plist
# launch dnsmasq
$ sudo launchctl load /Library/LaunchDaemons/homebrew.mxcl.dnsmasq.plist

to test, disable all networks and run:

$ azk agent start
$ dig dev.azk.io
$ ping -c 4 dev.azk.io

if someone can test and if it works without problems, we can see a way to implement this. cc/ @alexferreira

hi @gullitmiranda tested the solution offline and not had any problems, I had to offline thoroughly test because I need some stuff online, I am using online and already there was the problem twice efetuei the request for api and has failed, or came in api then sent the same request again and passed, it happened at two different points of application. to put a log on the api to confirm that this not getting

thanks for the feedback @alexferreira. I'll try to replicate this problem. Perhaps it will be necessary to make a restart in the application or Agent when there are changes in the network.

This problem can also be related to issue #588.

@gullitmiranda Added the dnsmas as reported, the problem still persisted, only ended when I added the local dns configuration of the machine ip 127.0.0.1 making before it get on an external dns first verificasse on site
