Server Preparation and Software Tools

set of parameters that the remote server delivers. By default, the phone resynchronizes on power-up and at
intervals that are configured in the profile. When the user connects the phone at the customer premises, the
device downloads the updated profile and any firmware updates.
This process of preprovisioning, deployment, and remote provisioning can be accomplished in many ways.
Server Preparation and Software Tools
The examples in this chapter require the availability of one or more servers. These servers can be installed
and run on a local PC:
• TFTP (UDP port 69)
• syslog (UDP port 514)
• HTTP (TCP port 80)
• HTTPS (TCP port 443).
To troubleshoot server configuration, it is helpful to install clients for each type of server on a separate server
machine. This practice establishes proper server operation, independent of the interaction with the phones.
We also recommend that you install these software tools:
• To generate configuration profiles, install the open source gzip compression utility.
• For profile encryption and HTTPS operations, install the open source OpenSSL software package.
• To test the dynamic profile generation and one-step remote provisioning using HTTPS, we recommend
• To verify secure exchanges between provisioning servers and the phones, install an Ethernet packet

sniffer (such as the freely downloadable Ethereal/Wireshark). Capture an Ethernet packet trace of the
interaction between the phone and the provisioning server. To do so, run the packet sniffer on a PC that
is connected to a switch with port mirroring enabled. For HTTPS transactions, you can use the ssldump
utility.
