[Gluster-devel] CLIENT_PORT_CIELING (sic)

[Raghavendra G]

Hi,

How many protocol/client translators are you using? Can you mail the volume
specification file? glusterfs tries to bind to privileged ports which are
free. It cannot bind to ports which are already being used. No need to
change the value of CLIENT_PORT_CEILING, since if the client cannot bind to
any privileged ports it will try to bind to non privileged ones. But If the
authentication being used on server side is ip based, it requires client to
be bound to a privileged port.

regards,
