NAME
rwalld — network rwall server
SYNOPSIS
/usr/lib/netsvc/rwall/rpc.rwalld
[-l
log_file]
[-e|-n]
DESCRIPTION
rwalld
is an RPC server that handles
rwall
requests (see
rwall(1)).
rwalld
calls
wall
to send a message to all users logged into the host on which
rwalld
is running (see
wall(1)).
inetd
invokes
rwalld
through
/etc/inetd.conf
(see
inetd(1M)).
Options
rwalld
recognizes the following options and command-line options:
- -l log_file
Log any errors to
log_file.
Errors are not logged if the
-l
option is not specified.
Information logged to the log file
includes date and time of the error,
the host name, process ID and name of the function generating the error,
and the error message.
Note that different services can share a single log file
because enough information is included
to uniquely identify each error.
- -e
Exit after serving each RPC request.
Using the
-e
option, the
inetd
security file
/var/adm/inetd.sec
can control access to RPC services.
- -n
Exit only if:
portmap
dies (see
portmap(1M)),
another
rpc.rwalld
registers with
portmap,
or
rpc.rwalld
becomes unregistered with
portmap.
The
-n
option is more efficient
because a new process is not launched for each RPC request.
Note, this option is the default.
