Starting from version 11 the TruView appliances ship with a firewall called Firewalld. Firewalld is by default available when using CentOS 7. The default configured listener ports at TVF are udp/2055 and udp/6343. If other ports are configured the firewall configuration has to verified and altered.

Commands

Switch user:

# sudo su -

Verify firewall:

# firewall-cmd --zone=public --list-ports

Alter firewall:

# firewall-cmd --zone=public --add-port=2056/udp
# firewall-cmd --zone=public --add-port=2056/udp --permanent

Several internal processes on TruView version 11 appliances are being monitored by a small utility called Consul. Consul only monitors local processes and is also available TVC and TVP.

This utility is configured to look for the listener ports that the Tracker ships with; udp/2055 and udp/6343. In case different listeners are used the utility will show a warning. Configuring this utility to look after the right listener ports will make these warning disappear.

Altering Consul configuration

# vi /opt/tv/manager/consul.d/nftracker.json

Restarting Consul

When this is done, restart the utility.

# systemctl restart tv-manager-client

Within a few moments all warings should be gone.
