edit (nano or vi) " /etc/default/tftpd-hpa " and add “sleep 30” on the top line so it looks like :
[I][B]sleep 30[/B][/I]
[I][B]# /etc/default/tftpd-hpa[/B][/I]
[I][B]# FOG Modified version[/B][/I]
[I][B]TFTP_USERNAME=“root”[/B][/I]
[I][B]TFTP_DIRECTORY=“/tftpboot”[/B][/I]
[I][B]TFTP_ADDRESS=“0.0.0.0:69”[/B][/I]
[I][B]TFTP_OPTIONS=“-s”[/B][/I]
