This lens parses /etc/inetd.conf. The current format is based on the
syntax documented in the inetd manpage shipped with Debian's openbsd-inetd
package version 0.20080125-2. Apologies if your inetd.conf doesn't follow
the same format.
Each top-level entry will have a key being that of the service name (the
first column in the service definition, which is the name or number of the
port that the service should listen on). The attributes for the service all
sit under that. In regular Augeas style, the order of the attributes
matter, and attempts to set things in a different order will fail miserably.
The defined attribute names (and the order in which they must appear) are as
follows (with mandatory parameters indicated by [*]):
address -- a sequence of IP addresses or hostnames on which this service
should listen.
socket[*] -- The type of the socket that will be created (either stream or
dgram, although the lens doesn't constrain the possibilities here)
protocol[*] -- The socket protocol. I believe that the usual possibilities
are "tcp", "udp", or "unix", but no restriction is made on what you
can actually put here.
sndbuf -- Specify a non-default size for the send buffer of the connection.
rcvbuf -- Specify a non-default size for the receive buffer of the connection.
wait[*] -- Whether to wait for new connections ("wait"), or just terminate
immediately ("nowait").
max -- The maximum number of times that a service can be invoked in one minute.
user[*] -- The user to run the service as.
group -- A group to set the running service to, rather than the primary
group of the previously specified user.
command[*] -- What program to run.
arguments -- A sequence of arguments to pass to the command.
In addition to this straightforward tree, inetd has the ability to set
"default" listen addresses; this is a little used feature which nonetheless
comes in handy sometimes. The key for entries of this type is "address"
, and the subtree should be a sequence of addresses. "*" can
always be used to return the default behaviour of listening on INADDR_ANY.
