Specifications of a contract

A flat pricing with ETH: USD - $0.02 per token (50 tokens to 1 USD)
Coin rate should be $0.02 (can just use the live feed from www.oraclize.it or similar)
Token supply: 1 billion, selling 150 million e.g. $3M cap.
Token: 8 decimals
Multisig wallet for the proceeds, as per gnosis (as that doesn't seem to have had any issues vs. parity)
Ensure tokens are reserved and allocated by a certain date when they unlock to subscribers
No ETH cap: Anyone can buy as many tokens as they like until all tokens are sold
Sale ends when 150m tokens (out of 1bn) allocated to contract run out or a certain date is reached
Ideally the smart contract should verify in etherscan and fit into the token tracker

Write contracts
Study zeppelin in depth and then learn to test for this: logic bugs, failed sends, recursive calls, overflow, poison data, exposed functions, exposed secrets, dust spam, replay attack, miner vulnerabilities, malicious creator, off-chain safety, cross-chain attacks, tx-origin problems, stack depth exhaustion, etc.

1- Connection Timeout Added

Issues Resolved: #72, #59
Description Glutton support number of services (protocol handlers) so each service mean number of connection on that service. So It crash after some time with error: [user.tcp] accept tcp [::]:5000: accept4: too many open files, and this error was due to the allowance of limited number of open file descriptors by the operating system. There was no deadline set for opened connections so most of the connections never get closed. In result, the number of opened connections gradually cross the maximum open file descriptors limit and cause panic. So I added connection timeout = 72 second, number of opened connection will never reach the open file descriptor limit. Another reason was Freki; Glutton useses freki as a networking core so frek
