List of TCP and UDP Port Numbers from Wikipedia, the Free Encyclopedia
List of TCP and UDP port numbers From Wikipedia, the free encyclopedia This is a list of Internet socket port numbers used by protocols of the transport layer of the Internet Protocol Suite for the establishment of host-to-host connectivity. Originally, port numbers were used by the Network Control Program (NCP) in the ARPANET for which two ports were required for half- duplex transmission. Later, the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) needed only one port for full- duplex, bidirectional traffic. The even-numbered ports were not used, and this resulted in some even numbers in the well-known port number /etc/services, a service name range being unassigned. The Stream Control Transmission Protocol database file on Unix-like operating (SCTP) and the Datagram Congestion Control Protocol (DCCP) also systems.[1][2][3][4] use port numbers. They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist. The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses.[5] However, many unofficial uses of both well-known and registered port numbers occur in practice. Contents 1 Table legend 2 Well-known ports 3 Registered ports 4 Dynamic, private or ephemeral ports 5 See also 6 References 7 External links Table legend Official: Port is registered with IANA for the application.[5] Unofficial: Port is not registered with IANA for the application. Multiple use: Multiple applications are known to use this port. Well-known ports The port numbers in the range from 0 to 1023 are the well-known ports or system ports.[6] They are used by system processes that provide widely used types of network services. -

Bitcoin 2: Freedom of Transaction
Bitcoin 2: Freedom of Transaction Sid Angeles and Eric Gonzalez [email protected] AF76 05E5 EB15 2B00 AB18 204C 11C9 1C8B EA6C 7389 [email protected] 3A85 7ABC 9453 96E4 B9DB 2A11 7370 E15E 8F60 2788 Donations: 1btctwojvohHSLaXaJAHWebZF2RS8n1NB Revision 2 July 23, 2013 Abstract We propose a set of changes to the original Bitcoin protocol (called Bitcoin 2) that allows Bitcoin to evolve into a system that is future-proof against developing threats to its original vision – an alternative, decentralized payment system which allows censorship-resistant, irreversible transac- tions. Bitcoin 2 strives to be a minimal set that lays the foundations for a long-lived system capable of delivering the original Bitcoin vision, with enough room for growth to layer additional im- provements on top of it. These changes include a sliding blockchain with fixed block sizes, the redistribution of dead coins with an unforgeable lottery, enforced mixing, and miner ostracism. The proposed changes require a proactive fork of the original Bitcoin block chain, but they allow final transfers of existing coins into Bitcoin 2 and a reuse of the existing Bitcoin infrastruc- ture. 1 Introduction The Bitcoin peer-to-peer electronic cash system [11] was introduced in 2009 and it proved to be a remarkable piece of work which found widespread adoption. The system was started with the explicit goal of providing a completely alternative payment system without a single point of failure that allows anonymous, but not untraceable, transactions. However, certain shortcomings in the original protocol and unforeseen developments inside and outside of the growing Bitcoin ecosystem threaten these very goals and there is good reason to believe that Bitcoin could develop into a system that is a complete perversion of the original vision – a com- pletely transparent payment system with very few points of control which has been totally absorbed by the established financial and regulatory environment. -
Terabyte Sneakernet: the Carry-On Data Center by Drew Hamre
December 2007 Terabyte SneakerNet: The Carry-on Data Center By Drew Hamre I recently helped relocate a data center for a US government agency, moving system images from Virginia to a consolidated facility in Minnesota. During ‘cutover’ weekend, production systems in Virginia were dropped and remained unavailable until data could be refreshed at the Minnesota data center and the new systems could be brought online. To minimize downtime, the time allotted for refreshing data across locations was extremely brief. email This data transfer was daunting for two reasons: the amount of data being moved was large (as much as two-terabytes would be moved during cutover weekend), and the network between the two sites was slow. Portable media were the only viable alternative, but these devices would need to meet extremely difficult requirements. They would need to be fast (due to the brief transfer window), inexpensive (no hardware funds were budgeted) and portable (devices needed to be hand-carried by agents to meet security mandates). Ideally, the team needed to find fast, cheap transfer devices that could be stowed in an airliner’s overhead bin. This paper reviews alternatives for the transfer, focusing on the latest generation of commodity Network Attached Storage (NAS) devices that allowed agents to transfer as much as 12-terabytes in a single carry-on duffle bag. Background: Transitioning Data Centers At the time of the transition, both data centers were fully functional: Virginia supported production, while Minnesota (a parallel environment running pre-staged system images on new hardware) supported acceptance testing. Minnesota’s parallel environment included a full snapshot of Virginia’s file system and databases (roughly 10-terabytes in total).
