[root@clovem ~]
# yum install telnet-server -y //安装telnet服务端
[root@clovem ~]
# cat /etc/xinetd.d/telnet //开启telnet的托管服务
# default: on
# description: The telnet server serves telnet sessions; it uses \
#unencrypted username/password pairs for authentication.
service telnet
{
flags= REUSE
socket_type= stream
wait= no
user= root
server=
/usr/sbin/in
.telnetd
log_on_failure+= USERID
disable= no
//
将
yes
改为no
}
[root@clovem ~]
# service xinetd restart //重启托管服务使配置文件生效

如下操作使root用户登录生效
[root@clovem ~]# mv /etc/securetty /etc/securetty.bak
这样, root 就可以直接进入 Linux 主机了。不过,建议不要这样做。也可以在普通用户进入后,切换到root用户,拥有root的权限。
