rsh命令配置于使用

安装环境：一台centos6.10虚拟机，一台centos7.5虚拟机，全部使用root用户登录。

两台机器上都要安装rsh、rsh-server、xinetd包。

两台机器都要关闭防火墙并配置/etc/hosts映射。

修改/etc/xinetd.d/下的三个文件，rlogin，rexec，rsh，将里面的disable=yes改为disable=no。如果没有这三个文件，创建即可。

如下：

rexec

# default: off

# description: Rexecd is the server for the rexec() routine.  The server \

# provides remote execution facilities with authentication based \

# on user names and passwords.

service exec

{

  socket_type   = stream

  wait      = no

  user      = root

  log_on_success    += USERID

  log_on_failure    += USERID

  server      = /usr/sbin/in.rexecd

  disable     = no

}

rlogin

# default: on

# description: rlogind is the server for the rlogin() program.  The server \

#       provides a remote login facility with authentication based on \

#       privileged port numbers from trusted hosts.

service login

{

        socket_type             = stream

        wait                    = no

        user                    = root

        log_on_success          += USERID

        log_on_failure          += USERID

        server                  = /usr/sbin/in.rlogind

        disable                 = no

}

rsh

# default: on

# description: The rshd server is the server for the rcmd() routine and, \

#       consequently, for the rsh() program.  The server provides \

#       remote execution facilities with authentication based on \

#       privileged port numbers from trusted hosts.

service shell

{

        disable = no

        socket_type             = stream

        wait                    = no

        user                    = root

        log_on_success          += USERID

        log_on_failure          += USERID

        server                  = /usr/sbin/in.rshd

}

然后修改/etc/pam.d/下的rlogin、rexec、rsh三个文件，将里面的#auth       required     pam_securetty.so这行注释掉，使得root用户可以远程登录。

然后再两台机器上重启xinetd服务即可互相登录了。
