tftpd-hpa service must be restarted before working after fresh boot
- by Steve
I'm running Ubuntu 12.04 inside a VirtualBox VM. I've installed tftpd-hpa so I can boot an embedded Linux device via tftp.
My problem is that after a fresh boot of the VM, tftpd doesn't seem to work until I restart the service, after which is works great until the system is rebooted. The transcript below should explain the situation.
EDIT: After the fresh boot, I execute netstat -a | grep tftp and find nothing. After restarting the service, the same command returns udp 0 0 *:tftp *:* (whitespace removed). I think this might be the key to the problem, I'm just not sure how to resolve it.
I don't think it's related to this specific issue, but I had another problem with tftpd that was asked and answered in this question.
