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


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


DESCRIPTION
      rpc.rexd is the Sun RPC server for remote program execution.
      This daemon is started by inetd(1M) whenever a remote execu-
      tion request is made.
 
      For non-interactive 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 NFS to mount file systems specified  in  the  remote
      execution request.
 
 SECURITY
      rpc.rexd uses pam(3PAM) for account and session  management.
      The  PAM configuration policy, listed through /etc/pam.conf,
      specifies the modules to be used for  rpc.rexd.  Here  is  a
      partial  pam.conf file with rpc.rexd entries for account and
      session management using the UNIX module.
 
      rpc.rexd      account       required      /usr/lib/security/pam_unix.so.1
      rpc.rexd      session       required      /usr/lib/security/pam_unix.so.1
 
 
      If there are no entries for the rpc.rexd service,  then  the
      entries  for the "other" service will be used. rpc.rexd uses
      the getpwuid() call to determine whether the given user is a
      legal user.
 


OPTIONS
      -s    Secure. When specified, requests must have  valid  DES
            credentials.  If  the  request  does  not  have  a DES
            credential  it  is  rejected.  The  default  publickey
            credential is rejected. Only newer on(1) commands send
            DES credentials.
 
            If access is denied with an authentication error,  you
            may  have to set your publickey with the chkey(1) com-
            mand.
 
            Specifying the -s  option  without  presenting  secure
            credentials  will result in an error message: Unix too
            weak auth (DesONly)!
 


FILES
      /dev/ptsn
            pseudo-terminals used for interactive mode
