安装远程打印机错误，请帮忙解决
两台机器，一台hostname为server76，一台hostname为printsvr，在printsvr上安装了一台名为print的本地打印机。现在想在server76上安装一台远程打印机，指向printsvr上的print打印机。

使用scoadmin->;printers->rinter Manager->;printer->;Add Remote->;unix增加，host选择printersvr，在选择打印机的时候，出现错误：

Failed to retrieve list of local printers and their descriptions.

detail信息为:

Failed to retrieve list of local printers and their descriptions.
server76 failed to connect to server76.

Please check the following:
   * your network configuration
   * your network connection
   * rhost permissions on the remote site
   * that SCOadmin is installed at the remote site
Failure with connection to server.
Remote child on machine printsvr has terminated.
The child program /etc/sysadm.d/bin/osaserver has terminated.
Server process exited with exit(1).
Error with server process: Permission denied.

请问怎么解决？
如果是信任关系
需要将/.rhosts的属性应为600 ，请问rhosts 在什么目录下？该文件里应包含什么内容？
