再遇灵异事件：Oracle 云主机无法允许端口的问题

再遇灵异事件：Oracle 云主机无法允许端口的问题

有句古话叫做：“常在河边走，哪有不湿鞋”，也句话叫做“夜路走多了总会遇见鬼”，我推及一下得出结论：常常和Linux主机打交道，总会遇到灵异问题。 (图源：pixabay) 话说大概是十多个月以前，我历尽千辛万苦终于申请下来一个Oracle云主机的账户，之所以不辞辛劳地弄这个账户，是因为Oracle云主机账户有些终身免费的福利——比如两台低配云主机(VPS)。

每天进步一点点: 将node.js 应用绑定到80端口的方法

每天进步一点点: 将node.js 应用绑定到80端口的方法

历尽千辛万苦，我终于将node.js的应用运行了起来，看起来貌似一切正常的样子。可是新的问题来了，别人的网站都直接可以通过域名访问，并且一般都是80或者443(HTTPS)端口，而我这个是8080端口又是怎么回事？又该如何解决呢？ (图源：pixabay) 直接换端口的方式肯定是行不通的啦，因为Linux下是不允许普通用户应用绑定特权端口(0至1023)的，那就要想别的方法了。 iptables转发

每天进步一点点: Linux普通用户下程序绑定特权端口(iptables转发)

每天进步一点点: Linux普通用户下程序绑定特权端口(iptables转发)

我在Linux的普通用户下运行一组程序，想让其中的一个程序监听1024以下的端口，结果运行程序提示权限不足，无法绑定端口。 (图源：pixabay) 难道需要我把这组程序复制到root用户下，以root权限执行？那这样的话，为了安全我特意搞了个普通用户岂不是就没有意义了。想了想，最简单的办法就是使用iptables转发啦，执行下列指令即可： sudo iptables -t nat -A PREROUTING

基于无预置IP list的GFW IP解锁方法

基于无预置IP list的GFW IP解锁方法

在以往的基于路由、iptables解锁GFW IP封锁的方法中，均需要一份国内或国外的IP地址列表，然后进行策略路由。基于这种方案的解锁，需要人工去维护一张IP地址列表，其中基于chnroutes方案生成的国内IP地址列表就有8000多条记录,在加载的时候会比较耗时，同时给路由器带来一定负担。本文给出一种基于无IP列表的自动IP访问监测及路由更变策略。 1.

The firewall of Linux: IPTables

If you own a Linux server, you know how important securing it is. A server is available to the whole world, when it's connected to the internet, and soon bad guys will try to break in. Without a firewall

linux iptables 설명

iptables 란? iptables는 리눅스상에서 방화벽을 설정하는 도구로서 커널 2.4 이전 버전에서 사용되던 ipchains를 대신하는 방화벽 도구이다. iptables는 커널상에서의 netfilter 패킷필터링 기능을 사용자 공간에서 제어하는 수준으로 사용할 수 있다. 패킷필터링이란 지나가는 패킷의 해더를 보고 그 전체 패킷의 운명을 결정하는 것을 말한다.

I've been watching my connection, as usual, and I noticed some strange addresses that keep coming up. Some of them are new but a few I have seen before. When I block these addresses it actually enhances
