對(duì)于Linux新手來(lái)說(shuō)，在各發(fā)行版之間困惑得進(jìn)行選擇和不斷增加的數(shù)量實(shí)在令人頭暈，這就是寫作本文的原因，其中列出的10個(gè)（附加一個(gè)值得一提的FreeBSD，BSD一族中最為流行的）是被全世界的Linux玩家最廣泛使用的發(fā)行版。沒有數(shù)據(jù)來(lái)支持這個(gè)結(jié)論，而且對(duì)于人們特殊的需求也許會(huì)有其它更好的版本來(lái)滿足，但作為一般原則，這些版本都使用廣泛還有活躍的論壇或者郵件列表來(lái)讓你在遇到問(wèn)題卡住的時(shí)候求救。 Ub

Linux掃盲篇：CentOS、Ubuntu、Gentoo

Linux最早由Linus Benedict Torvalds在1991年開始編寫。在這之前，Richard Stallman創(chuàng)建了Free Software Foundation（FSF）組織以及GNU項(xiàng)目，并不斷的編寫創(chuàng)建GNU程序（此類程序的許可方式均為GPL: General Public License）。在不斷的有杰出的程序員和開發(fā)者加入到GNU組織中后，便造就了今天我們所看到的Lin

iftop是什么？iftop是類似于top的實(shí)時(shí)流量監(jiān)控工具。iftop有什么用？Iftop工具主要用來(lái)顯示本機(jī)網(wǎng)絡(luò)流量情況及各相互通信的流量集合，如單獨(dú)同哪臺(tái)機(jī)器間的流量大小，非常適合于代理服務(wù)器和iptables服務(wù)器使用，這樣可以方便的查看各客戶端流量情況。iftop可以用來(lái)監(jiān)控網(wǎng)卡的實(shí)時(shí)流量（可以指定網(wǎng)段）、反向解析IP、顯示端口信息等，詳細(xì)的將會(huì)在后面的使用參數(shù)中說(shuō)明。安裝iftop使用
