OS：Ubuntu8.10-intrepid

Ubuntu8.10 网络基本设置

 

//配置IP

sudo vi /etc/network/interfaces  

auto l1
iface l1 inet loopback
auto eth0
iface eth0 inet static
address 192.168.0.220   //这里填IP地址
netmask 255.255.255.0   //这里填掩码
gateway 192.168.0.3     //这里填网关

 

//配置DNS
sudo vi /etc/resolv.conf
改为
domain domain
search domain
nameserver 202.114.0.242
nameserver 202.114.20.131

//重启网络服务
/etc/init.d/networking restart

// 解决网络连接被重置的问题（新浪博客比较明显）:
   ubuntu默认的网络连接mtu为576，我们所在网络环境通才情况下mtu是1500，因此做如下修改：
   i.网络连接管理器里“编辑连接”设定MTU值
   ii./etc/network/interfaces加上这样一句：
      post -up /sbin/ifconfig mtu 1500

 

//关闭IPV6：
sudo gedit /etc/modprobe.d/aliases
然后修改这一行:
alias net-pf-10 ipv6
为:
alias net-pf-10 off #ipv6

 

sudo vi /etc/modprobe.d/bad_list

最后添加

alias net-pf-10 off

//注释掉 hosts 文件中所有与 IPV6 的行：

sudo vi /etc/hosts
 

 

//安装ssh

apt-get install openssh-server openssh-client

 

停止/启动/重启ssh：

/etc/init.d/ssh stop/start/restart

 

//配置ssh 密码认证

sudo vi /etc/ssh/sshd

#RSAAuthentication yes
#PubkeyAuthentication yes  添加#注销

PasswordAuthentication yes 减去#生效

sudo ps -aux |grep sshd

sudo Kill -HUP sshd_pid

sudo ssh

 

 

Ubuntu8.10 基本应用设置

 

// 如何让终端不显示完整路径的解决办法：

编辑用户主目录的.bashrc文件,eg:(~/.bashrc),修改其PS1参数中的\w为\w,如下例子
if [ "$color_prompt" = yes ]; then
   PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\W\[\033[00m\]\$ '
else
   PS1='${debian_chroot:+($debian_chroot)}\u@\h:\W\$ '
fi

 

//KDM模式切换成GDM模式：

移除原先启动画面： sudo aptitude --purge remove usplash
安装上ubuntu默认启动画面： sudo aptitude install usplash-theme-ubuntu

//更改登录模式

KDE的登录模式：sudo dpkg-reconfigure kdm
GONE的登录模式：sudo dpkg-reconfigure gdm

 

//启用root用户登录：
　$sudo gedit /etc/gdm/gdm.conf

  AllowRoot=false  改成：AllowRoot=true

//禁用 root 帐号
$sudo passwd -l root

 

// 用ubuntu 的root登录也能出中文

sudo vi /root/profile

LANG="zh_CN.UTF-8"
LANGUAGE="zh_CN:zh"

 

配置/etc/apt/sources.list
sudo cp /etc/apt/sources.list  /etc/apt/sources.list.backup

代码:

sudo rm -rf /etc/apt/sources.list
sudo vi /etc/apt/sources.list
