I am running tftp-hpa server which was installed as shown below on Ubuntu 15.04
sudo apt-get install tftpd-hpa
The configuration file name tftp-hpa is located in
/etc/defaults as shown
# /etc/default/tftpd-hpa RUN_DAEMON="yes" TFTP_USERNAME="tftp" TFTP_DIRECTORY="/var/lib/tftpboot" TFTP_ADDRESS="[::]:69" TFTP_OPTIONS="--secure"
The problem is that I can transfer files from
/var/lib/tftpboot only once. In order to perform further transfer I have to issue the restart on the server as follows.
sudo /etc/init.d/tftpd-hpa restart
Failure to issue above command means that the tftpd server no longer respond to any tftp client request.
