温习一下telnet

/etc/init.d/./ipchains stop
/etc/init.d/./xinetd restart //重起xinetd

rpm -qa|grep telnet-server 查看是否安装了telnet服务
rpm -hiv telnet-server-***.***.rpm 安装telnet

/etc/xinetd.d/telnet文件，将disable=yes 改成no

vi /etc/securetty
pts/0
pts/1

vi /ect/security/access.conf 指定允许登录的终端IP

vi /etc/hosts
ip win2k-client client //允许win客户登陆

推荐用SSH
