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
Sent 722 bytes in 0.0 seconds
atftp> quit
ls -l /tftpboot/
total 4
-rwxrwxrwx 1 ruchi ruchi 707 2008-07-07 23:07 hda.txt

Great job!
Just a little mistake, maybe this command “tftp 192.168.1.2″ should be “atftp 192.168.1.2″.

Very helpful - have achieved transfer from Ubuntu client to Ubuntu server (named UbuntuServer_2 with address 192.168.1.2) on in-house LAN.
Next step is to be able to transfer from Windows XP to Ubuntu server.
Results so far, using ‘ftp http://ftp.hostname‘ as suggested in Windows X Help:
ftp http://ftp.UbuntuServer_2 -> Unknown host
ftp http://ftp.192.168.1.2 -> Uknown host
ftp 192.168.1.2 -> connected to 192.168.1.2, then after a few secs, connection closed by remote host.
Question: any suggestions.
Eventual aim is to be able to upload files from NuSphere phpEd (Standard) which only supports ‘passive’ FTP, installed on the Windows XP PC to the Ubuntu sever.
