Update the Local Hosts file for data collection

Add the Portal IP Address to the Local Hosts file on the Data Collector server or on any available client with web-browsing capabilities.
Note:
Only edit the local hosts file if a DNS entry hasn't already been set up in your enterprise to resolve both http://aptareportal.yourdomain.com and http://aptareagent.yourdomain.com to the Portal IP address.
Login to the Data Collector server.
On a Linux server:
```
vi /etc/hosts
```
Add entries for itanalyticsportal.yourdomain.com and aptareagent.yourdomain.com, both resolving to the Portal server IP address.
On a Windows server:
```
edit C:\Windows\System32\drivers\etc\hosts
```
Add entries for itanalyticsportal.yourdomain.com and itanalyticsagent.yourdomain.com, both resolving to the Portal server IP address.
On the Data Collector server, add entries to the local hosts file, both resolving to the Portal server IP address.
Example:
- 172.16.2.2 itanalyticsportal.<yourdomain>.com
- 172.16.2.3 itanalyticsagent.<yourdomain>.com
