Set up linux slave

In some folder (probably the home folder), do:

sudo apt-get buildbot buildbot-slave
buildslave create-slave slave 10.0.2.2:9989 example-slave pass
buildslave start slave

slave is the folder that the configuration will go into, example-slave is the name of the slave, pass is the password, 10.0.0.2 is the IP address of the host that the VM uses (shouldn't need to change it, see OSX host instructions below)

This should start the Twisted server, yielding output like:

ian@ian-VirtualBox:~$ buildslave start slave/
Following twistd.log until startup finished..

Configuration of OSX Virtualbox host

Thanks to http://stackoverflow.com/questions/1261975/addressing-localhost-from-a-virtualbox-virtual-machine and the comment of spsaucier you basically need to do the following, copied verbatim:

To enable this on OSX I had to do the following:

1. Shut your virtual machine down.

2. Go to VirtualBox Preferences -> Network -> Host-only Networks -> click the "+" icon. Click OK. 3.Select your box and click the "Settings" icon -> Network -> Adapter 2 -> On the "Attached to:" dropdown, select "Host-only Adapter" and your network (vboxnet0) should show up below by default. Click OK. 4. Once you start your box up again, you should be able to access localhost at http://10.0.2.2/

You can refer to it by localhost and access other localhosted sites by adding their references to the hosts file (C:windowssystem32driversetchosts) like the following:

10.0.2.2    localhost
10.0.2.2    subdomain.localhost
