  61                 system call. It should contain a single
  62                 newline-terminated host name string. The
  63                 host name may be a free-form string up to 64 characters
  64                 in length, however it is recommended that it consists
  65                 only of 7bit ASCII lower-case characters and no spaces or dots,
  66                 and limits itself to the format allowed for DNS domain
  67                 name labels, even though this is not a
