NAME

writesrv − Lets users send messages to and receive messages from a remote system

SYNOPSIS

/usr/sbin/writesrv

DESCRIPTION

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

The writesrv command 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 on the port defined in the /etc/services file.  All requests for service go as messages to this socket. 

The writesrv daemon is started automatically by the /sbin/init.d/write program during system boot if the WRITESRV environment variable is defined properly in the /etc/rc.config file. To start writesrv automatically during system boot, edit the /etc/rc.config file as superuser to include the following entry:

rcmgr set WRITESRV   yes

To prevent writesrv from starting automatically during system boot, edit the file to include the following entry:

rcmgr set WRITESRV   no

By default, the WRITESRV environment variable is not set in the /etc/rc.config file and therefore the writesrv daemon does not start automatically when the system is booted. 

You can start the writesrv daemon manually with the following command:

 /sbin/init.d/write   start

You can stop the writesrv daemon manually with the following command:

/sbin/init.d/write   stop

NOTES

If the writesrv daemon terminates abnormally (that is, because of a system crash, a power failure, or the kill -9 command), someone must manually clean out the /usr/spool/writesrv directory to remove any files left behind.
