ox_launch()invokes a process to execute command on a host host and enables Asir to communicate with that process. If the number of arguments is 3, `ox_launch' in dir is invoked on host. Then `ox_launch' invokes command. If host is equal to 0, all the commands are invoked on the same machine as the Asir is running. If no arguments are specified, host, dir and command are regarded as 0, the value of
get_rootdir()and `ox_asir' in the same directory respectively.
ox_launch()invokes `xterm' to display standard outputs from command. If
X11is not available or one wants to invoke servers without `xterm', use
ox_launch_nox(), where the outputs of command are redirected to `/dev/null'. If the environment variable
DISPLAYis not set,
Abe the host on which Asir is running, and
Bthe host on which the peer process will run.

Awithout supplying a password.
Xis also used, let
Xserverauthorize the relevant hosts. Adding the hosts can be done by command
