|
Waits for a given port to become accessible (or inaccessible) on a local or remote server.
|
||
|
|
||
|
This is useful for when services are not immediately available after their init scripts return -- which is true of certain
|
||
|
Java application servers. It is also useful when starting guests with the virt module and
|
||
|
needing to pause until they are ready.
