VoIP Hopper 1.0 has been released, with several new features, and a
new project website:
http://voiphopper.sf.net

What is VoIP Hopper?
VoIP Hopper is a GPLv3 licensed security tool, written in C, that
rapidly runs a VLAN Hop into the Voice VLAN on specific Ethernet
switches. VoIP Hopper does this by mimicking the behavior of an IP
Phone, in Cisco, Avaya, and Nortel environments. VoIP Hopper is a VLAN
Hop test tool but also a tool to test VoIP infrastructure security.

New Features:
* *Nortel Support:* VoIP Hopper can now automatically discover the
Voice VLAN ID used in Nortel IP Phone networks and VLAN Hop!
* *DHCP client:* A fully integrated DHCP client! VoIP Hopper now
implements DHCP messaging as function calls instead of relying on the
old 'dhcpcd' client. This opens up the door for future VLAN Discovery
mechanisms for other vendors, such as Alcatel.
* *New CDP mode:* A new CDP Spoof mode that uses a pre-constructed IP
Phone packet of a Cisco 7971G-GE! Now you can VLAN Hop faster by
spoofing CDP and don't have to construct your own CDP Packet!
* *Error correction with VLAN Interfaces:* Implemented a feature that
checks to see if the IP address is already configured for the voice
interface before running the VLAN Hop and DHCP request
* *Bug fix 1:* Fixed an important libpcap bug with pcap_next_ex read
timeout when CDP sniff mode was used (-c 0)
