-- Written in python -- Releases its IP, waits a specified time in configuration file, and then renews its IP from the DHCP lease. Repeat this process if you aren't in a different class C when you renew. Keep repeating until you are in a different class C than you were originally _AND_ the class C does not exist for a different computer in HOP_CONNECTION table Example: 126.96.36.199 current IP Release [wait X minutes] Renew New IP: 188.8.131.52 [This is in the same class C, so it should release and renew again] and log this 184.108.40.206 into the HOP_LOG database, with the proper status code as mentioned in the Schema Release [wait X minutes] Renew New IP: 220.127.116.11 [This is a different class C. It should stop running release and renew and log the new IP to HOP_CONNECTION, as long as this class C does not exist in HOP_CONNECTION. If it does, release and renew again.] - Local configuration file, which allows you to tune - Length of time to wait while renewing DHCP lease - Number of attempts that result in the same IP before reporting the failure in the log, see below - A unique name for each install -- Uses two database tables: - HOP_CONNECTION table - stores all current IPs -- When starting a hop, remove our current IP, but remember it so we aren't in the same class C as our current IP. -- When completing a hop, check against all other IPs - if any other IPs are in the same class C, hop again, otherwise record our new IP. - HOP_LOG table - stores history of hop activity -- No matter what happens w/ HOP_CONNECTION, also record that activity in HOP_LOG Schema: -- HOP_CONNECTION - id - timestamp - install name - ip -- HOP_LOG - timestamp - install name - status (1 = success, 2 = collides with previous class C, 3 = collides with another servers class C, 4 = too many failed attempts to change ip) - ip
