You can check to see if a TFTP server is set up with the following command:
- host $ rpm -q tftp-server 
You should expect to see output similar to:
- tftp-server-0.39-2 
NOTE: Your version may be different than the one listed above. This is OK, the version above is just an example.
If it is not setup, you can follow these steps:
- Download a TFTP server for your Linux host. You can search the internet for "tftp-server". You can find the RPM package for download here
- Install the TFTP server package 
- host $ rpm -ivh <tftp-server package name> 
 
- Confirm that TFTP is installed 
- host $ /sbin/chkconfig --list | grep tftp 
 
- Turn on the TFTP server 
- host $ /sbin/chkconfig tftp on 
 
The default root location for TFTP files is /tftpboot.
