Changing the default ports for psid(8)
28 ParaStation5 Administrator's Guide
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.
