rex(1)
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 re
- mote 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 certifica
- tion 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
- 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 be
- low. Rex only recognizes the escape character `~' after a new
- line.
- · . terminate connection
- · ^Z suspend connection
- · ? help message
- · ~ send the escape character
