PAR Technologies V5 manual Port

Page 32

Changing the default ports for psid(8)

and change the default port number 888.

Modify the entry

port

= 888

within the file /etc/xinet.d/psidstarter to reflect the newly assigned port numbers.

In addition, the ParaStation daemon psid(8) uses the UDP port 886 for RDP connections. To change this port, use the RDPPort directive within parastation.conf. See parastation.conf(5) for details.

The port numbers must be identical on all cluster nodes! Restart xinetd and psid on all nodes to activate the modifications.
