REXD(1M)            RISC/os Reference Manual             REXD(1M)



NAME
     rexd - RPC-based remote execution server

SYNOPSIS
     /usr/etc/rpc.rexd

DESCRIPTION
     rexd is the Sun RPC server for remote program execution.
     The daemon must be started from the system startup scripts.

     For noninteractive programs, the standard file descriptors
     are connected directly to TCP connections.  Interactive pro-
     grams involve pseudo-terminals, in a fashion that is similar
     to the login sessions provided by rlogin(1).  This daemon
     may use the NFS to mount file systems specified in the
     remote execution request.

FILES
     /dev/ttyqn          pseudo-terminals used for interactive
                         mode
     /etc/passwd         authorized users
     /tmp_rex/rexd?????? temporary mount points for remote file
                         systems.

SEE ALSO
     on(1), in the User's Reference Manual, and rex(3R),
     exports(4), in the Programmer's Reference Manual.

     rsh
     provides similar functionality.

DIAGNOSTICS
     Diagnostic messages are sent to the system log, and returned
     to the requestor.

BUGS
     Should be better access control.

RESTRICTIONS
     Root cannot execute commands using rexd client programs such
     as on(1).

     The exit status of programs which voluntarily terminated
     abnormally cannot be distinguished from those which were
     externally terminated with signals.

ORIGIN
     NFS 4.0
