Install atftp Server in Ubuntu
sudo aptitude install atftpd
This will complete the installation
Using atftpd
By default atftpd server starts using inetd so we need to tell atftpd to run as a server directly, not through inetd.Edit /etc/default/atftpd file using the following command
sudo gedit /etc/default/atftpd
Change the following line
USE_INETD=true
to
USE_INETD=false
save and exit the file
Now you need to run the following command
sudo invoke-rc.d atftpd start
Configuring atftpd
First you need to create a directory where you can place the files
sudo mkdir /tftpboot
sudo chmod -R 777 /tftpboot
sudo chown -R nobody /tftpboot
sudo /etc/init.d/atftpd restart
Security configuration for atftp
Some level of security can be gained using atftp libwrap support. Adding proper entry to /etc/hosts.allow and /etc/hosts.deny will restrict access to trusted hosts. Daemon name to use in these files is in.tftpd.
/etc/hosts.allow /etc/hosts.deny
in.tftpd : FQD or IP
atftp client installation
Advance Trivial file transfer protocol client,atftp is the user interface to the Internet ATFTP (Advanced Trivial File Transfer Protocol), which allows users to transfer files to and from a remote machine. The remote host may be specified on the command line, in which case atftp uses host as the default host for future transfers.
sudo aptitude install atftp
That’s it you are ready to transfer your files using tftp clients
Testing tftp server
Tranfering file hda.txt from 192.168.1.100 (Client using tftp) to 192.168.1.2 (Server 192.168.1.100). Get an example file to transfer (eg. hda.txt)
touch /tftpboot/hda.txt
chmod 777 /tftpboot/hda.txt
ls -l /tftpboot/
total 0
-rwxrwxrwx 1 ruchi ruchi 223 hda.txt
atftp 192.168.1.2
atftp> put hda.txt

sudo chmod ugoa+w /srv/tftp
echo hello > /srv/tftp/hello.txt
atftp –verbose -g -l local_hello.txt -r hello.txt 127.0.0.1

thats a dash dash in front of verbose
“atftp –verbose -g -l local_hello.txt -r hello.txt 127.0.0.1″
and it does not auto start atftpd in Ubuntu12.10

One other thing in 12.10
edit /etc/default/atftpd to contain INET_ANY (0.0.0.0) as the IP to make ports on…….
USE_INETD=false
OPTIONS=”–tftpd-timeout 300 –bind-address 0.0.0.0 –retry-timeout 5 –mcast-port 1758 –mcast-addr 239.239.239.0-255 –mcast-ttl 1 –maxthread 100 –verbose=5 /srv/tftp”

Thank you.

Hi, I am running Ubuntu Studio 12.04. I configured atftd and can start it by running invoke-rc.d command and file transfer works perfectly well. However, it does not start at boot time. The log has an error message saying that it cannot bind to my ip interface. Still I can start it by running invoke-rc.d command manually.
No other process is using port 69. I have also changed the /etc/rcX.d to start up atftpd after rlinetd is started just to make sure that the port is available for binding but still no success.
It is not a major issue but interesting find out why this is happening. Would appreciate any suggestions to resolve this.
thanks
