Spectrum Network Configuration Manager (NCM) utilizes tftp file transfers for some host configuration captures. By default, on most Linux OS installs, tftp is disabled. If Spectrum is installed on a Linux server and NCM is part of the Spectrum install, tftp will need to be enabled to ensure proper functionality.
Enabling tftp on Linux
tftp is an xinetd-based service; start it with the following commands as root:
/sbin/chkconfig --level 345 xinetd on
/sbin/chkconfig --level 345 tftp on
These commands configure the xinetd and tftp services to immediately turn on and also configure them to start at boot time in runlevels 3, 4, and 5.
