My tftpd-hpa file :

/etc/default/tftpd-hpa

FOG Modified version

TFTP_USERNAME=“fog”
TFTP_DIRECTORY=“/tftpboot”
TFTP_ADDRESS=“172.16.192.5:69”
TFTP_OPTIONS=“-s”

My tftpboot directory:
~fog:/tftpboot$ ls -la
total 860
drwxr-xr-x 3 fog root 4096 mai 26 15:54 .
drwxr-xr-x 26 root root 4096 mai 26 15:54 …

-rw-r–r-- 1 fog root 147728 mai 26 15:54 vesamenu.c32

And an extract of my dhcpd3.conf: (ubuntu server) :
next-server 172.16.192.5;
filename “undionly.kpxe”;

The message error :
PXE-T01 : File not Found
PXE-E3B : TFTP error - File Not Found

Thank you for your help…
