修改/etc/vsftpd/vsftpd.conf

问题出在了设置被动模式上

一上手直接加了下边几行。

pasv_addr_resolve=YES
pasv_address=myhostname
pasv_min_port=60000
pasv_max_port=61000

然后给iptables加了20跟60000-61000的端口段。

本机测试，没问题，本以为OK了

结果，其他内网机器都访问不了被动模式，自己用另外一台机子通过filezilla访问居然返回的是：

Response: 227 Entering Passive Mode (127,0,0,1,235,14)
Command: LIST
Error: Transfer channel can’t be opened. Reason: 対象のコンピュータによって拒否されたため、接続できませんでした。
Error: Could not retrieve directory listing

iptables没问题
那就出在vsftpd的配置了。
搞来搞去，把pasv_address改成ip地址，结果好使了，但是俺这机子IP是自动获取啊。
上边几个关于被动模式的参数也改了改试试，没啥进展。

最后一怒，把
pasv_addr_resolve=YES
pasv_address=myhostname

都给注释掉了，重启服务，居然好了。。

汗了一会，码字留念。

PS:

如果是

pasv_addr_resolve=NO           
pasv_address=myhostname
的话，报500错误。
返回消息为 500 OOPS: invalid pasv_address

yum install scim-lang-japanese

然后更改前端全局变量 热键 为CTRL+SPACE

2，sudo gedit /etc/apt/sources.list
在文件中加入一行
deb http://morgoth.free.fr/ubuntu feisty-backports main
3，sudo apt-get update
4， $ sudo apt-get install audacious audacious-mac audacious-plugins

OK了

2，安装mplayer：
sudo apt-get update
sudo apt-get install mplayer
3，取得钥匙
sudo wget http://www.medibuntu.org/sources.list.d/gutsy.list -O /etc/apt/sources.list.d/medibuntu.list
wget -q http://packages.medibuntu.org/medibuntu-key.gpg -O- | sudo apt-key add -
4，更新系统
sudo apt-get update
5，安装w32codecs
sudo apt-get install w32codecs libdvdcss2

终于他妈的出来正式版了。

不过发现sony的本装linux那个不舒坦，老死机，fedora，ubuntu，opensuse，centos，统统不好使

看来还是老老实实给老婆当小说阅读器吧。

1，先搜索了一下，得到以下解释
IP                       IP地址
Netmark           子网掩码
Gateway            默认网关
HostName         主机名称
DomainName   域名
DNS                   DNS的IP

2，需要修改的文件常有

/etc/sysconfig/network
/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/resolv.conf
/etc/hosts

以下是我的设置
/etc/sysconfig/network
这里主要是指定了网关

NETWORKING=yes
NETWORKING_IPV6=no
GATEWAY=192.168.1.1
HOSTNAME=localhost.localdomain

/etc/sysconfig/network-scripts/ifcfg-eth0
这里主要指定IP获得方式（static），ip地址，子网掩码，网络类型

# Broadcom Corporation NetXtreme BCM5721 Gigabit Ethernet PCI Express
DEVICE=eth0
#BOOTPROTO=dhcp
BOOTPROTO=static
IPADDR=192.168.1.21
NETMASK=255.255.255.0
TYPE=Ethernet
HWADDR=XX:XX:XX:XX:XX:XX
ONBOOT=yes

/etc/resolv.conf
指定DNS（我在这里就吃了亏，没设置前网络地址怎么也无法解析）

search localdomain
nameserver 192.168.1.1

/etc/hosts
我没设置，是用来定义主机名的。

Problem

Installing Ruby on Rails on CentOS (or Redhat), the RubyGems part of the official installation instructions (or the instructions listed in this excellent SitePoint book which I’m working through at the moment) may yield this result:

# cd /usr/local/src/rubygems-0.9.2
# ruby setup.rb

< --- lib
/usr/local/lib/ruby/site_ruby/1.8/rubygems/remote_fetcher.rb:4:in `require': no such file to load — zlib (LoadError)

Solution

A zlib error? Hrm. Double check zlib and zlib-devel are installed (I’m not sure if zlib-devel is needed but I installed it for good measure).

# yum install zlib zlib-devel

Then:

# cd /usr/local/src/ruby-1.8.5-p2/ext/zlib/
# ruby extconf.rb --with-zlib-include=/usr/include --with-zlib-lib=/usr/lib
# make
# make install

Next, install RubyGems. Note that running “ruby setup.rb” on it’s own doesn’t seem to work, try this:

# cd /usr/local/src/rubygems-0.9.2/
# ruby setup.rb config
# ruby setup.rb setup
# ruby setup.rb install

All’s good in the hood. Now continue with the rest of the installation.

# gem install rails --include-dependencies

Enjoy.
