ｂｕｉｌｄｒｏｏｔ学习（九）——ａｔ９１ｓａｍ９ｇ４５软件平台更新

(117)ptpd、ptpd2
PTPd is an open source implementation of the Precision Time Protocol for Unix-like computers.
(118)ｐｕｒｅｆｔｐｄ
PureFTPd ^[1]  是一款专注于程序健壮和 软件安全的免费FTP服务器软件（基于BSD License）。其可以在多种类Unix操作系统中编译运行，包括 Linux、 OpenBSD、 NetBSD、 FreeBSD、 DragonFly BSD、 Solaris、 Tru64、 Darwin、 Irix and HP-UX。PureFTPd还有Android移植版本。
（１１９）ｐｕｔｔｙ
PuTTY是一个Telnet、SSH、rlogin、纯TCP以及串行接口连接软件。较早的版本仅支持Windows平台，在最近的版本中开始支持各类Unix平台，并打算移植至Mac OS X上。除了官方版本外，有许多第三方的团体或个人将PuTTY移植到其他平台上，像是以Symbian为基础的移动电话。PuTTY为一开放源代码软件，主要由Simon Tatham维护，使用MIT licence授权。随着Linux在服务器端应用的普及，Linux系统管理越来越依赖于远程。在各种远程登录工具中，Putty是出色的工具之一。Putty是一个免费的、Windows x86平台下的Telnet、SSH和rlogin客户端，但是功能丝毫不逊色于商业的Telnet类工具。目前最新的版本为0.67 Beta
（１２０）quagga
Quagga is a routing software suite,providing implementations of OSPFv2, OSPFv3, RIP v1 and v2, RIPng and BGP-4for Unix platforms, particularly FreeBSD, Linux, Solaris and NetBSD. Quaggais a fork of GNU Zebra which wasdeveloped by Kunihiro Ishiguro. The Quagga tree aims to build a moreinvolved community around Quagga thanthe current centralised model of GNUZebra.
强大的路由器软件
（１２１）radvd
The router advertisement daemon (radvd) is run by Linux or BSDsystems acting as IPv6 routers. It sends Router Advertisement messages,specified by RFC2461, to a local Ethernet LAN periodically and when requested by anode sending a Router Solicitation message. These messages are requiredfor IPv6 stateless autoconfiguration.
(122)rp-pppop

PPPoE (Point-to-Point Protocol over Ethernet) is a protocol used by many ADSL Internet Service Providers. Roaring Penguin has a free PPPoE client for Linux and Solaris systems to connect to PPPoE service providers.

Dubbed RP-PPPoE, this open-source product is ideal for Linux users with a DSL “modem” whose Internet service provider uses PPPoE. Before you download this software, check whether or not you really need it. If your ISP uses PPPoE, but has given you a router, you may not need a PPPoE client on your Linux box. DHCP may work fine.

(123)rsh-redone

（１２４）ｒｐｃｂｉｎｄ

RPC即Remote Procedure Call Protocol（远程过程调用协议），RPCBIND用于取代旧版本中的portmap组件。 简单说，RPCBIND就是为了将不同服务与对应的端口进行绑定，以便支持机器间的互操作

（１２５）ｒｓｙｎｃ

rsync是类unix系统下的数据镜像备份工具——remote sync。一款快速增量备份工具 Remote Sync，远程同步 支持本地复制，或者与其他SSH、rsync主机同步。

（１２６）rtottent

rTorrent is a quick and efficient BitTorrent client that uses, and is in development alongside, the libTorrent (not to be confused with libtorrent-rasterbar) library. It is written in C++ and uses the ncurses programming library, which means it uses a text user interface. When combined with a terminal multiplexer (e.g. GNU Screen or Tmux) and Secure Shell, it becomes a convenient remote BitTorrent client

(127)rtptools

The rtptools distribution consists of a number of small applicationsthat can be used for processing RTP data.

(128)samba4

Samba是在Linux和UNIX系统上实现SMB协议的一个免费软件，由服务器及客户端程序构成。 SMB（Server Messages Block，信息服务块）是一种在 局域网上共享文件和打印机的一种 通信协议，它为局域网内的不同计算机之间提供文件及打印机等资源的共享服务。SMB协议是客户机/服务器型协议，客户机通过该协议可以访问服务器上的共享文件系统、打印机及其他资源。通过设置“NetBIOS over TCP/IP”使得Samba不但能与局域网络主机分享资源，还能与全世界的电脑分享资源。

（１３０）ｓｅｒ２ｎｅｔ
串口转网络，这个功能在工控领域很有用之前的很多设备多有串口，现在要组网了，就需要串口网关了
（１３１）shairport-sync
Shairport Sync is an AirPlay audio player — it plays audio streamed from iTunes, iOS devices and other AirPlay sources such as Quicktime Player and ForkedDaapd, among others.Audio played by a Shairport Sync-powered device stays synchronised with the source and hence with similar devices playing the same source. In this way, synchronised multi-room audio is possible without difficulty. (Hence the name Shairport Sync, BTW.)

Shairport Sync does not support AirPlay video or photo streaming.

This is the stable “master” branch. Changes and updates are incorporated into this branch relatively slowly. To access the development version, where all the latest changes are made first, please switch to the “development” branch.

（１３１）smcroute

SMCRoute is a command line tool to manipulate the multicast routes inthe UNIX kernel. It supports both IPv4 and IPv6 multicast routing.

SMCRoute can be used as an alternative to dynamic multicast routers like or in setups where static multicast routes should bemaintained and/or no proper IGMP or MLD signaling exists.

Multicast routes exist in the UNIX kernel only as long as a multicastrouting daemon is running. Only one multicast routing daemon can beactive at a time, so it’s impossible to run SMCRoute and, e.g., at the same time. Linux does however support multiple routingtables, which SMCRoute not yet supports.

SMCRoute is maintained collaboratively at GitHub. Previously thecode was hosted and maintained by Debian at Alioth and before thatby Carsten Schill, the original author.

（１３２）socat (133)Socketcand

Socketcand is a daemon that provides access to CAN interfaces on a machine via a network interface. The communication protocol uses a TCP/IP connection and a specific protocol to transfer CAN frames and control commands. The protocol specification can be found in ./doc/protocol.md

应该是通过网络控制ＣＡＮ接口，现在做的部分设备，要求有ＣＡＮ转以太网功能

（１３４）softether

该软件是一个能虚拟网卡和集线器（HUB）的工具，只要可以访问互联网，都可以使用它来组建远程局域网。在此虚拟的局域网上能进行所有物理局域网上的操作。可以互相访问，可以联网玩只支持局网的游戏（TCP/IP）。该软件能够突破防火墙拦截，信息包都经过加密，安全上不存在问题。SoftEther分为虚拟集线器(HUB)和虚拟网卡两部分，使用服务器/客户端的方式工作，虚拟集线器就是服务器，虚拟网卡就是客户端。连接时利用SoftEther提供的连接管理工具将虚拟网卡连接到远端的虚拟集线器上，这样你的计算机就相当于与该虚拟集线器上连接的其他计算机处于同一个局域网之内。

（１３５）spawn-fcgi
原来很多人都用 Lighttpd 的 Spawn-fcgi 进行 FastCGI 模式下的管理工作，不过有不少缺点。而 PHP-fpm 的出现多少缓解了一些问题，但 PHP-fpm 有个缺点就是要重新编译，这对于一些已经运行的环境可能有不小的风险(refer)。 原来 spawn-fcgi 版本也比较乱的，期待独立后的项目能更稳定一些。这会给很多 Web 站点带来便利。
