如何在SuSE Linux下安装配置telnet服务

1。如果安装了telnet、telnet-server的rpm包，就跳到2。，否则安装这个包。

2。修改telnet服务配置文件

vi

/etc/xinetd.d/telnet

service

telnet{disable

=

yes

flags

=

REUSE

socket_type

=

streamwait

=

nouser

=

root

server

=

/usr/sbin/in.telnetd

log_on_failure

+=

USERID}将disable=yes行前加#，或者改为disable=no

3。重新启动xinetd守护进程

由于telnet服务也是由xinetd守护的，所以安装完telnet-server，要启动telnet服务就必须重新启动xinetd

[root@localhost

root]#service

xinetd

restart

4。关闭系统的防火墙

linux系统默认的防火墙是“high”。

（方法：[root@localhost

root]#

setup

选择：“firewall

configuration”

选择：security

level——“no

firewall”）

5。如果想允许root以telnet登入linux主机？因为

telnet

不是很安全，自然预设的情况之下就是无法允许

root

以

telnet

登入

Linux

主机！想要开放

root

以

telnet

登入

Linux

主机的话，可以这样做：

在

auth

required

/lib/security/pam_securetty.so

这行前加

#

，即把这行注释掉就行

最简单的方法是新建一个不允许登陆的系统用户：

useradd sydsftp -s /sbin/nologin

passwd sydsftp设置密码

再给/var/ftp目录授权

chown sydsftp:sydsftp /var/ftp

修改vsftp配置文件，允许匿名用户可读，允许本地用户可读可写：

vi /etc/vsftp/vsftpd.conf

anonymous_enable=YES

anon_upload_enable=NO

local_enable=YES

write_enable=YES

chroot_local_user=YES 将FTP本地用户禁锢在宿主目录中

anon_root=/var/ftp 设置主目录

local_root=/var/ftp 设置本地用户主目录

回答这个问题很蛋疼啊

有一部分参考了插件calendar.vm

将下面2个函数放入vimrc或者在plugin文件夹新建一个.vim文件

调用：

:call Reply_Baidu()<cr>
