REXD(8C)                                                              REXD(8C)



NAME
       rexd, rpc.rexd - RPC-based remote execution server

SYNOPSIS
       /usr/etc/rpc.rexd [-s]

DESCRIPTION
       rexd  is  the Sun RPC server for remote program execution.  This daemon
       is started by inetd(8C) whenever a remote execution request is made.

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

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

OPTIONS
       -s     Secure.  When specified, requests must have  valid  des  creden-
              tials.   If  the  request  does  not have a DES credential it is
              rejected.  The default publickey credential is  rejected.   Only
              newer on commands send DES credentials.

              If  access  is denied with an Authentication error, you may have
              to set your publickey with the chkey(1) command.

SEE ALSO
       chkey(1), on(1C), rlogin(1C), rex(3R), exports(5), inetd.conf(5),  pub-
       lickey(5), inetd(8C)

DIAGNOSTICS
       Diagnostic  messages  are normally printed on the console, and returned
       to the requestor.

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