Start Squid via `service squid start`
Now that we have flask and jinja, we can create a mock DGA service to
deploy with MaaS:
-* Download the files in
[this](https://gist.github.com/cestella/cba10aff0f970078a4c2c8cade3a4d1a) gist
into the `/root/mock_dga` directory
-* Make `rest.sh` executable via `chmod +x /root/mock_dga/rest.sh`
+* Download the files in
[this](https://gist.github.com/cestella/cba10aff0f970078a4c2c8cade3a4d1a) gist
into the `$HOME/mock_dga` directory
+* Make `rest.sh` executable via `chmod +x $HOME/mock_dga/rest.sh`
This service will treat `yahoo.com` and `amazon.com` as legit and
everything else as malicious. The contract is that the REST service exposes an
endpoint `/apply` and returns back JSON maps with a single key `is_malicious`
which can be `malicious` or `legit`.
## Deploy Mock DGA Service via MaaS
+The following presumes that you are a logged in as a user who has a
+home directory in HDFS under `/user/$USER`. If you do not, please create
one
+and ensure the permissions are set appropriate.

Would it be good to add the following example steps picking 'metron' as a
user?
```
su - hdfs -c "hadoop fs -mkdir /user/metron"
su - hdfs -c "hadoop fs -chown metron:metron /user/metron"
```
