The issue is caused because the tftpd-hpa --secure flag is not being used. I've added it to /etc/default/tftpd-hpa: TFTP_OPTIONS="-s" Now I see: sudo tcpdump -ni eth0 -v -T tftp 'udp' tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes 18:25:50.528436 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto UDP (17), length 47) 10.254.251.51.42972 > 10.254.251.2.69: 19 RRQ "pxelinux.0" octet 18:25:50.551265 IP (tos 0x0, ttl 64, id 31434, offset 0, flags [none], proto UDP (17), length 544) 10.254.251.2.44414 > 10.254.251.51.42972: 516 DATA block 1 18:25:50.553521 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto UDP (17), length 32) 10.254.251.51.42972 > 10.254.251.2.44414: 4 ACK block 1 ... ** Summary changed: - PXe Error: Only absolute filenames allowed + PXE Error: Only absolute filenames allowed ** This bug has been marked a duplicate of bug 531123 pxe boot with tftpd-hpa failed with error: Forbidden Directory -- PXE Error: Only absolute filenames allowed https://bugs.launchpad.net/bugs/544377 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to tftp-hpa in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
