3.4 Uploading files with TFTP
You can copy files from the host system to the target system using the target’s TFTP client. Please note that
a TFTP server has to be installed on the host system. Usually, a TFTP server can be installed on every Linux
distribution. To install the TFTP server under Debian based systems with apt, the following command must be
executed on the host system:
$ sudo apt-get install xinetd tftpd tftp
The TFTP server must be configured as follows in the /etc/xinetd.d/tftpd file on the host system in order to
provide the directory /srv/tftp as TFTP directory:
service tftp
{
protocol = udp
port = 69
socket_type = dgram
wait = yes
user = nobody
server = /usr/sbin/in.tftpd
server_args = /srv/tftp
disable = no
}
The /srv/tftp directory must be created on the host system with the following commands:
$ sudo mkdir /srv/tftp
$ sudo chmod -R 777 /srv/tftp
$ sudo chown -R nobody /srv/tftp
After the above modification the xinetd must be restarted on the host system with the new TFTP service with the
following command:
$ sudo service xinetd restart
From now on, you can access files in this directory from the target.
Example: Copying the file myapp from the host system to the target’s /usr/bin directory. To achieve this, first
copy the file myapp to your TFTP directory on the host system:
