方圆快捷用的是WAYOS~~~

回老家去了,在方圆快捷住,正好带了笔记本上网,习惯性的看下网络拓扑,DHCP,DNS,和网关都是192.168.2.1
登陆一下网关,发现是WAYOS,默认密码自然登陆不上去。
开了23端口
,也登不上去,不知道是BCM还是X86的系统。这边大概几百个房间,猜想可能是X86的版本

4443端口是不是跟远程服务器连接的后门端口哦?

关掉lighttpd目录浏览

装了lighttpd,发现lighttpd 目录浏览功能默认是打开的,如果找不到 index 文件就允许目录浏览(也就是 apache 的index,在lighttpd 叫  virtual directory listings)这样不安全,还是关掉的好。

关掉某个目录(比如下面例子的 download 目录)的浏览功能,ubuntu 下在 /etc/lighttpd/lighttpd.conf 后面添加

dir-listing.activate = "enable"
$HTTP["url"] =~ "^/download($|/)" {
dir-listing.activate = "disable"
}
关闭所有目录浏览直接用 dir-listing.activate = "disable" ,/etc/init.d/lighttpd force-reload 重启lighttpd,搞定!

ncdu-磁盘目录占用空间分析工具

安装ncdu
目前的最新版本是1.6,下载地址:http://soft.vpser.net/manage/ncdu/ncdu-1.6.tar.gz

下载后执行:

tar zxvf ncdu-1.6.tar.gz
cd ncdu-1.6/
./configure
make && make install

即可安装,如果是Debian/Ubuntu的话更简单直接执行apt-get install ncdu,即可安装上。

使用方法:
执行ncdu会提示选择目录,输入目标目录,回车,即可列出当前目录下的文件及目录的大小,默认按照大小进行排序,如图

可以使用数字键,1、2、3进行切换,1为快捷键,2为显示格式说明,3为ncdu版权信息。

常用快捷键
n :按文件名进行排序
s :按文件大小进行排序
r :重新统计当前文件夹大小
g :用#或百分比显示各文件/目录的大小所占的百分比,例如:

关于hi-vps的VPS

买了HI-VPS
256MB的openvz,突发512MB内存,看了下系统里面默认装了一堆东西,我喜欢纯净系统,全干掉吼吼。

apt-get remove apache*
apt-get remove sendmail*
apt-get remove bind9
apt-get remove fetchmail
apt-get remove procmail
这下清净了~~~
