I installed tftpd-hpa and tftp in Ubuntu 12.04 LTS.
when I check the status of tftpd-hpa with service command, it shows running.
zlf@ubuntu:~$ service tftpd-hpa status
tftpd-hpa start/running
But when I check its process, there is no running PID to show.
zlf@ubuntu:~$ ps -ef |grep ftp
zlf 5607 5397 0 15:02 pts/1 00:00:00 grep --color=auto ftp
zlf@ubuntu:~$ ps -ef |grep hpa
zlf 5609 5397 0 15:02 pts/1 00:00:00 grep --color=auto hpa
what happened? Is tftpd-hpa not a process or other reason?
By the way, I test tftpd-hpa by localhost, it doesn't work.
zlf@ubuntu:~$ tftp localhost
tftp> get test
Transfer timed out.
