[root@f27k system]# systemctl status tftp.socket ● tftp.socket - Tftp Server Activation Socket Loaded: loaded (/usr/lib/systemd/system/tftp.socket; enabled; vendor preset: dis Active: active (listening) since Sun 2018-01-21 21:49:54 CST; 3s ago Listen: [::]:69 (Datagram) [root@f27k system]# ps -eaf | grep tftp root 2983 1909 0 21:50 pts/2 00:00:00 grep --color=auto tftp So, the socket is activated but no in.tftpd service is running. Now, I do an "nc" on a remote system to activate.... [egreshko@meimei ~]$ nc -u 192.168.1.191 69 helo And now we see.... [root@f27k system]# ps -eaf | grep tftp root 2984 1 0 21:51 ? 00:00:00 /usr/sbin/in.tftpd -s /var/lib/tftpboot root 2987 1909 0 21:52 pts/2 00:00:00 grep --color=auto tftp [root@f27k system]# systemctl stop tftp.socket [root@f27k system]# ps -eaf | grep tftp root 2991 1909 0 21:52 pts/2 00:00:00 grep --color=auto tftpand to answer the question : of course systemctl <verb> mytftp.service like any other systemd servicesSo, really, your exercise wasn't need.
Thanks a lot for info!! Adrian
