DESCRIPTIONgnuspool.hosts is used to inform the GNUspool spooler and document management system, and in particular spshed(8) and xtnetserv(8), which other host machines are to be attached.
The host machines should in general be provided for in the standard file /etc/hosts or via the DNS.
The file consists of comment lines introduced by the # character, and of lines consisting of up to 4 fields, of which only the first is mandatory. These fields are as follows:
Host nameThis is the name of the host as given in the /etc/hosts file.
Alternatively an internet address of the form 18.104.22.168 may be given if necessary and an alias is provided on the next field, but this is not recommended.
Alias nameThis is the name of an alias to be used in preference to the host name to refer to the machine. To be particularly beneficial, this should be shorter than the host name.
If this field is not required, but subsequent fields are required, then the alias name may be replaced by a single - sign.
FlagsThis is a comma-separated list of markers to denote information about the connection. The currently-supported markers are probe, dos(username) and manual, any or all of which may be specified.
- Indicates that a datagram should be sent, and a reply awaited, from the host, before a full-blown connection is attempted. This is recommended wherever possible, or it is not sure in which order machines are booted.
- indicates that no connection at all is attempted. To connect to the machine in question, then gspl-conn(1) should be invoked.
- indicates that the host is ``trusted'' by the current machine, which transmits information about Windows clients and their password validations, so the other host need not make such enquiries.
indicates that no connection is attempted; the current machine is
acting as a server for Windows clients. The specified username is to be
considered as the owner of any jobs submitted, and the user to whom
charges should be applied and to which privileges apply; see
If (username) is omitted, then the Windows user is assumed, which should correspond to a user name on the host system.
Indicates that the whole entry identifies a ``roaming user'' who might
be using one of several Windows clients, possibly with IP addresses
assigned via DHCP. The host name in this case is replaced by the
Windows user name, and the alias gives the Unix user name if
If (machine) is specified, then a password is demanded at the Windows client if the client's IP address does not match that of machine.
- Is a synonym for client(username) kept for historical reasons.
- Is a synonym for clientuser(username) kept for historical reasons.
- Is a synonym for client (no username) kept for future extensions.
- Always demand the user's Unix password when first starting up.
TimeoutThis gives a timeout value in seconds after which the interface is to be considered closed following a connection or alternatively to await a connection after a probe request.
A default of 1000 seconds applies if none is specified.
In the case of Windows clients, the ``login'' is considered to be dropped after this time, and the user may be asked for a password again.
LOCAL ADDRESSOn some machines, the ``local'' host address may be different from that obtained by looking at the result of gethostname(3). To specify a different address for ``this'' machine, a line of the form:
may be specified, but this must precede all other host names in the file.
