为何重装系统后，远程磁带机无法使用

lhz750320

用下面命令备份：
ufsdump 0uf 192.168.1.201:/dev/rmt/0 /dev
出现提示：
DUMP: Writing 32 Kilobyte records
DUMP: Date of this level 0 dump: Tue May 27 16:44:01 2008
DUMP: Date of last level 0 dump: the epoch

里面的两个IP地址不一样，你没看出来吗？

不好意思，其实IP地址是一致的，我上传时，未改成一致，抱歉。

1.确认两台主机均在/.rhosts、/etc/.rhosts、/etc/hosts.equiv三个配置文件中，是否正确了配置互相信任的对方主机名(或IP地址)。例如：

#more /.rhosts
hostA

#more /etc/.rhosts
hostA

#more /etc/hosts.equiv
hostA root

2.检查/etc/pam.conf配置是否正确，PAM负责安全认证，如果未作正确设置，r系列命令(或其他远程操作)会出现信任问题，如果重装系统前备份了该文件，可以直接恢复到原来的配置，具体请参考如下配置：
