dig
和命令host
给出不完整的结果,或者(有时)给出核心转储Ubuntu 22.04. 两个命令均在版本“9.18.1-1ubuntu1-Ubuntu“”。
当我像这样运行它们时:
$ dig google.com +nssearch
$ host -C google.com
大多数时候输出是不完整的(没有输出或只有一行),其他时候它们核心转储. 这发生在x86_64系统。在一个arch64系统,它们输出一些行,然后它们悬挂。
所有系统均为 Ubuntu 22.04,命令版本与上述相同。以前的版本不会出现此问题。
示例运行:
$ dig google.com +nssearch
$ dig google.com +nssearch
$ dig google.com +nssearch
