writesrv(8)						      System Manager's Manual						       writesrv(8)

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 with 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. STARTING AND STOPPING writesrv. You can cause the writesrv daemon to be started during system boot with /sbin/init.d/write. The writesrv daemon starts automatically if the WRITESRV variable is defined properly in /etc/re.config. To start writesrv automatically during system boot, do the following as superuser. rcmgr set WRITESRV yes To prevent writesrv from starting automatically during system boot, do the following as superuser: rcmgr set WRITESRV no By default, writesrv is not set and therefore /usr/sbin/writesrv does not run. You can start the writesrv daemon manually as follows: /sbin/init.d/write start You can stop writesrv manually as follows: /sbin/init.d/write stop NOTES
If the writesrv daemon terminates abnormally (that is, for 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. RELATED INFORMATION
