我正在尝试将mail.aliases映射添加到我的NIS / YP服务器上的Makefile中。 我已经添加了“邮件”到要build立的地图列表，并确保它指向正确的别名文件（/ etc / aliases）。
我得到的问题是，当我运行make，我得到一个“callback超时”错误，如下所示：
mail.aliases – >“SlaveNisServer”：回叫超时
其他地图似乎build立成功。
有没有人知道这里可能会出现什么问题？
有可能你的从服务器设置不正确 – 尝试在SlaveNisServer上运行ypinit，并确保NIS（和rpcbind）守护进程正在运行：
/usr/lib/yp/ypinit -s MasterNisServer 谢谢。 帮助解决这个问题：

If there were warnings, please figure out what went wrong, and fix it.
此时，请确保/etc/passwd和/etc/group已被编辑，以便在激活NIS时使用您刚创build的数据库，而不是/etc ASCII文件。
