#Rhel 8 tftp server how to#

You’ll need to know how to use the correct options in order to get the tftpd server listening in stand-alone mode (that is to say, listening without xinetd). If you still insist on running tftpd without xinetd, consult the man pages for in.tftpd. The default settings work just fine and the config file already comes configured once you download xinetd and tftp-server via yum. That’s the default xinetd config file for the tftpd service. you can run tftpd without xinetd however, the xinetd config file keeps all the important tftpd options nice and tidy for you as we can see here: # cat /etc/xinetd.d/tftp When the server receives a request, xinetd will launch tftp with the necessary options so that files can be downloaded by the tftp client as requested.

In this post, xinetd will be used to listen for any tftp requests that come in from clients. Xinetd brings efficiency and security by being a single service that runs as needed– as opposed to having multiple, dormant services running needlessly in the background for most of their run time. You can launch xinetd once and have it wake up other intended services as needed. Why the need for xinetd? The xinetd daemon is a “super-daemon” or “super service” that listens for connection requests on behalf of other daemons and services. Log on to 192.168.100.5 and download the necessary programs make sure they survive reboots:

You will need superuser privileges on both your server and client in order to successfully perform all of these commands. We’ll designate our tftp server and tftp test client as 192.168.100.5 and 192.168.100.105 respectively. Let’s say we’re dealing with a private network– 192.168.100.0/24. Knowing how to setup a tftp server comes in quite handy when circumstances like these arise. tftp can also be used for network based installs or for booting up diskless systems. Many network devices such as Cisco routers and switches use tftp in order to download their IOS config updates.
