  • 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(3) 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(1) 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(3) routine and, 
    #       consequently, for the rsh(1) 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。
