The purpose of this tutorial is to provide a sample DHCP configuration for auto discovery of the PCoIP Management Console 2.x and newer.

In this set up the following were deployed:
  • CentOS 7.4 VM hosted on ESXi 5.5 server.
  • Configured the CentOS VM with two NICs (one on the corporate network and one on an isolated network for testing. This is not necessary as it is just to test on an isolated network and still have full access to the VM.)
  • As CentOS 7.4 VM was a fresh install, yum update was ran to ensure it had the latest patches and fixes.
  • Next, DHCP was installed - yum -y install dhcp
  • A 2nd NIC was assigned to DHCP for dhcpd to listen on. To do this modify /etc/sysconfig/dhcpd and add the following line - DHCPDARGS=ens192 replacing 192 with your NIC ID
  • Next, edit the default dhcpd.conf file located at /etc/dhcp. The exact configuration below.

NOTE: This is a sample configuration you will have to modify your file accordingly, cat was used to display the file contents.
[root@localhost ~]# cat /etc/dhcp/dhcpd.conf

#The fingerprint provided is the default Teradici SHA256 fingerprint.
#The PCoIP.URI is the IP address of the management console converted from ASCII to Hexidecimal
#wss://10.0.161.31 converted to hexidecimal = 77:73:73:3a:2f:2f:31:30:2e:30:2e:31:36:31:2e:33:31

}

To start and enable the dhcpd service run the commands below:
systemctl start dhcpd
systemctl enable dhcpd

Modify the firewall rule and reload:
firewall-cmd --add-service=dhcp --permanent
firewall-cmd --reload
