Requires Optional NFS Services Software

NAME

rwalld − network rwall server

SYNOPSIS

/usr/etc/rpc.rwalld [−l log_file] [−e | −n]

DESCRIPTION

rwalld is an RPC server that handles rwall(1) requests. rwalld calls wall(1) to send a message to all users logged into the host on which rwalld is running. 

inetd(1M) invokes rwalld through /etc/inetd.conf. 

Options

−l log_file Log any errors to the named log file, log_file. Errors are not logged if the −l option is not specified. 

Information logged to the 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 since enough information is included to uniquely identify each error. 

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

−n Exit only if:

• portmap(1M) dies,

• another rpc.rwalld registers with portmap(1M), or

• rpc.rwalld becomes unregistered with portmap(1M).

The −n option is more efficient since a new process is not launched for each RPC request.  Note, this option is the default.
