Setting up a TFTP server (OpenWrt WhiteRussian RC6)

1. edit /etc/ipkg.conf and include the RC6 backports repository if not already done

src backports http://downloads.openwrt.org/backports/rc6

2. install the atftpd package (the dependency bug is already reported, ticket #1022) -- atftpd and all dependencies require about 150k space on the flash

ipkg update
ipkg install atftpd libpthread

3. create a directory and a test file for your TFTP server

mkdir /atftpboot
echo "TFTP test" > /atftpboot/test.txt

4. start the TFTP server with

atftpd --daemon --port 69 /atftpboot

4.1. check if the TFTP server process is running and listening on port 69/UDP

ps ax | grep atftpd
548 nobody      412 S   atftpd --daemon --port 69 /atftpboot

netstat -an | grep "0:69"
udp        0      0 0.0.0.0:69              0.0.0.0:*

Everything is ok.

5. Test the server with a TFTP client
We test the TFTP server by receiving the test.txt file we created in step 3.

5.1. Windows TFTP client (Start -> Run -> CMD)

C:\>tftp <ip_of_router> GET test.txt
Transfer successful: 11 bytes in 1 second, 11 bytes/s

5.2. Linux atftp client

atftp --get --remote-file test.txt <ip_of_router>

6. create a simple start script /etc/init.d/S50atftpd and make it executable

#!/bin/sh
atftpd --daemon --port 69 /atftpboot

chmod +x /etc/init.d/S50atftpd

Add this to the OpenWrt wiki if you like.
