Testing our tftp server Create a file named test with some content in /tftpboot path of the tftp server Obtain the ip address of the tftp server using ifconfig command Now in some other system follow the following steps.

The installation is done by: # apt-get install tftpd-hpa Server Configuration The TFTP server can be started by one of two ways: directly as daemon, or via inetd. In the first case, running as daemon, the line starting with tftp in /etc/inetd.conf has to be commented (described here for openbsd-inetd or compatible): Excerpt: /etc/inetd.conf #tftp dgram udp http://askubuntu.com/questions/201505/how-do-i-install-and-run-a-tftp-server wait root /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /var/lib/tftpboot and it has to be enabled in the init script's configuration: Excerpt: /etc/default/tftpd-hpa RUN_DAEMON="yes" In the second case, running via inetd, the line starting with tftp in /etc/inetd.conf has to be uncommented (for Debian's default inet daemon openbsd-inetd): Excerpt: /etc/inetd.conf tftp dgram udp wait root /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /var/lib/tftpboot and it has to be disabled in the http://chschneider.eu/linux/server/tftpd-hpa.shtml init script's configuration: Excerpt: /etc/default/tftpd-hpa RUN_DAEMON="no" The root directory from where files can be downloaded by a client defaults to /var/lib/tftpboot. It can be changed to, e.g., to /new/tftp/root, if required: Excerpt: /etc/default/tftpd-hpa OPTIONS="-l -s /new/tftp/root" Files can be put into this directory and downloaded from a client without passing this root directory in its requests. Finally, restart openbsd-inetd and tftpd-hpa: # /etc/init.d/openbsd-inetd restart # /etc/init.d/tftpd-hpa restart Server Testing Put a file foo into the root directory of the TFTP server. Install a TFTP client: # apt-get install tftp and download the file (not neccessarily as root): $ tftp server.example.com tftp> get foo tftp> q The file should now exist into your current working directory. Networking Requirements Prerequisite: Shorewall In case of a packet filter (Shorewall), you will have to permit access from the clients. The difficulties resulting from changing source/destination ports in TFTP are automatically handled by the netfilter NAT/Conntrack helper modules that are loaded by Shorewall by default. Excerpt: /etc/shorewall/rules # TFTP # ACCEPT net $FW udp 69 # and restart the packet filter: # shorewall restart Back to index. 2015-07-20 09:00 Christian Schneider http://www.chschneider.eu/linux/server/tftpd-hpa.shtml
