NAME

        rex - remote execution
 

SYNOPSIS

        rex [-TAXpv] [-R port:lport] destination [command]
 

DESCRIPTION

        rex is a remote execution facility which is integrated with SFS.  The
        program allows users run to run programs on a remote machine or obtain
        a shell.  Like SFS file systems, remote execution servers can be named
        by self-certifying path names.
 
        The usage is as follows:
 
        rex [-TAXpv] [-R port:lport] destination [command]
 
        destination is one of the following:
 
        ·   a self-certifying hostname (location:hostid)
 
        ·   a self-certifying pathname (/sfs/... or /symlink-to-sfs/...)
 
        ·   any identifier which when processed through certification programs
            will yield a self-certifying pathname
 

OPTIONS

        -T  Disable pseudo-tty allocation.
 
        -A  Disable SFS agent forwarding.  By default, if there is no sfsagent
            running on the remote machine, rex will forward agent requests back
            to the sfsagent running on the local machine (e.g., when a user
            accesses an SFS file system or runs sfskey).
 
        -X  Disable X forwarding.  By default, the rex client will set up a
            dummy X server which receives connections from clients on the
            remote machine.  These connections are forwarded over the encrypted
            rex channel to the local X server.  rex sets the DISPLAY environ‐
            ment variable appropriately on the remote side.  Furthermore, X
            connections are authenticated using a ‘spoofed’ MIT-MAGIC-COOKIE-1.
 
        -p  Force rex to connect to the destination even if it cannot be
            resolved into a valid self-certifying path name.
 
        -v  Verbose mode.
 
        -R port:lport
            Forward TCP connections made to port on the remote host to lport on
            the local machine.
 
        The rex command supports the escape sequences listed below.  Rex only
        recognizes the escape character ‘~’ after a newline.
 
        ·   . terminate connection
 
        ·   ^Z suspend connection
 
        ·   ? help message
 
        ·   ~ send the escape character
        dirsearch(1), newaid(1), sfsagent(1), sfskey(1), ssu(1), sfs_config(5),
        sfs_hosts(5), sfs_srp_params(5), sfs_users(5), sfsauthd_config(5),
        sfscd_config(5), sfsrosd_config(5), sfsrwsd_config(5), sfssd_config(5),

        The full documentation for SFS is maintained as a Texinfo manual.  If
        the info and SFS programs are properly installed at your site, the com‐
        mand info SFS should give you access to the complete manual.
