rex
reference guiderex
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:
-T
-A
sfsagent
running on the remote machine, rex
will
forward agent requests back the sfsagent
running on the
local machine (e.g., when a user accesses an SFS file system or runs
sfskey
).
-X
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
environment variable appropriately on the remote side.
Furthermore, X connections are authenticated using a `spoofed'
MIT-MAGIC-COOKIE-1.
-p
rex
to connect to the destination even if
it cannot be resolved into a valid self-certifying path name.
-v
-R port:lport
The rex
command supports the escape sequences listed below.
Rex only recognizes the escape character `~' after a newline.
