writesrv Daemon

Purpose

Allows users to send messages to and receive messages from a remote system.

Syntax

writesrv

Description

The writesrv daemon allows users to send messages to users on a remote system and receive responses from users on a remote system with the write command.

The writesrv utility receives incoming requests from a write command and creates a server process to handle the request. This server process communicates with the client process (write) and provides whatever services are requested.

To perform these services, the writesrv daemon creates a socket that is attached to the port defined in the /etc/services file. All requests for service are sent as messages to this socket.

Note: If the writesrv daemon terminates abnormally (such as a system crash, power failure, or the kill -9 command), the /var/spool/writesrv directory must be manually cleaned out to remove any files left behind by the writesrv daemon.

Examples

1. To start the writesrv daemon from the /etc/rc script, enter:

   /usr/sbin/writesrv

   The writesrv daemon is started from the /etc/rc script. This is the usual way the daemon is started.
2. To start the writesrv daemon using the System Resource Controller (SRC), enter:

   startsrc -s writesrv &

   The writesrv daemon is started using SRC.
