Hi!
I am planning to test a service for availability and if the service
is not
available anymore, fence the node and start the service on another
node.
Therefore, i need a clue how to probe a port with system tools.
Sure, with telnet there is a possibility to check. But i have no
idea to
avoid the interactivity. So it is too difficult for me to implement
and
usually not allowed in this environment.
On Solaris, there is the "ping -p" command to test the availability
of a
application waiting on a port. But for Redhat, i have no clue.
Could you please help?
Net Cat? (man nc ) ?
