我可以使用 SSH 别名作为主机名的一部分吗？

Question

我在一个域下有一堆我经常连接的机器； apollo.my.university.edu hades.my.university.edu zeus.my.university.edu 我对它们中的每一个都使用相同的配置设置。而不是在我的.ssh/config,

Host apollo
    Hostname apollo.my.university.edu

Host hades
    Hostname hades.my.university.edu

Host zeus
    Hostname zeus.my.university.edu

是否有一种 makefile-esque 方式使用别名同时完成所有主机名？就像是

Host apollo hades zeus
    Hostname *.my.university.edu

Answer 1

尝试

Host apollo hades zeus
    Hostname %h.my.university.edu

如果我man ssh_config正确阅读，这应该可以满足您的需求。

HostName
         Specifies the real host name to log into.  This can be used to specify nicknames
         or abbreviations for hosts.  If the hostname contains the character sequence
         `%h', then this will be replaced with the host name specified on the command
         line (this is useful for manipulating unqualified names).  The default is the
         name given on the command line.  Numeric IP addresses are also permitted (both
         on the command line and in HostName specifications).
