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
provide the directory
/srv/tftp
service tftp
{
protocol
port
socket_type
wait
user
server
server_args
disable
}
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
copy the file myapp to your TFTP directory on the host system:
$ cp ./myapp /srv/tftp/
The host system is assumed to have the ip address 192.168.1.100. On the target system, type:
root@vincell:~# tftp -g 192.168.1.100 -r myapp -l /usr/bin/myapp
3.5 Uploading files with SFTP
You can exchange files between the host system and the target system using an SFTP (Secure FTP) client on
