rwalld — network rwall server


/usr/lib/netsvc/rwall/rpc.rwalld [-l log_file] [-e|-n]


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)).


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.


Exit after serving each RPC request. Using the -e option, the inetd security file /var/adm/inetd.sec can control access to RPC services.


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.


rwalld was developed by Sun Microsystems, Inc.
