|
|
This module uses a valid administrator username and password to execute an
|
|
arbitrary command on one or more hosts, using a similar technique than the "psexec"
|
|
utility provided by SysInternals. Daisy chaining commands with '&' does not work
|
|
and users shouldn't try it. This module is useful because it doesn't need to upload
|
|
any binaries to the target machine.
