55 | <title>Description</title> | |
56 | ||
57 | <para>The <filename>/etc/hostname</filename> file | |
58 | configures the name of the local system that is set | |
409dee2e | 59 | during boot using the |
6a7e63ef LP |
60 | <citerefentry><refentrytitle>sethostname</refentrytitle><manvolnum>2</manvolnum></citerefentry> |
61 | system call. It should contain a single | |
e9dd9f95 JSJ |
62 | newline-terminated hostname string. The |
63 | hostname may be a free-form string up to 64 characters | |
64 | in length; however, it is recommended that it consists | |
65 | only of 7-bit ASCII lower-case characters and no spaces or dots, | |
7640a5de | 66 | and limits itself to the format allowed for DNS domain |
6a7e63ef | 67 | name labels, even though this is not a |
7640a5de | 68 | strict requirement.</para> |
6a7e63ef | 69 | |
e9dd9f95 | 70 | <para>Depending on the operating system, other |
6a7e63ef | 71 | configuration files might be checked for configuration |
e9dd9f95 | 72 | of the hostname as well, however only as fallback.</para> |
