|
# USAGE
|
|
# Create a link to this script. The link name should be the name of the remote
|
|
# program to execute on the remote_machine. Modify the workspace_dir and
|
|
# remote_machine variables below as needed.
|
|
|
|
# The first time a program is remotely executed, this script will automatically
|
|
# generate the keys needed to perform password-less connections between the
|
|
# local machine and the remote machine and vice versa. The remote machine
|
|
# password will only need to be entered once.
|
|
|
|
# remote_machine is the network address of the machine on which the
|
|
# remote_program is setup. remote_user is the username to log into the
|
|
# remote_machine as.

|
# remotely. The default value of "$HOME" assumes the files required by the
|
|
# remote_program are someplace in the $HOME directory. If the files reside
|
|
# outside of the $HOME directory change $HOME to reflect the correct location.
|
|

|
|
# need changing unless the network interface is not eth0 or the line below fails
|
|
# to determine the correct ip address.
