root@changeme:/# cat /lib/systemd/system/proftpd.service [Unit] Description=ProFTPD FTP Server Wants=network-online.target After=network-online.target nss-lookup.target local-fs.target remote-fs.target [Service] Type=forking Environment=OPTIONS= CONFIG_FILE=/etc/proftpd/proftpd.conf EnvironmentFile=-/etc/default/proftpd ExecStartPre=/usr/sbin/proftpd --configtest -c $CONFIG_FILE ExecStart=/usr/sbin/proftpd -c $CONFIG_FILE $OPTIONS ExecReload=/bin/kill -HUP $MAINPID PIDFile=/run/proftpd.pid [Install] WantedBy=multi-user.target root@changeme:/# We can see test string: ExecStartPre=/usr/sbin/proftpd --configtest -c $CONFIG_FILE And we can see start string: ExecStart=/usr/sbin/proftpd -c $CONFIG_FILE $OPTIONS In the start string, it uses $CONFIG_FILE and $OPTIONS, but in the test string, it does not use $OPTIONS. So, options in the /etc/default/proftpd do not work, when proftpd testing config before start. When the server haven't correct hostname or it is unable to resolve the hostname, proftpd can't start. For solve this, we can add in the /etc/default/proftpd: OPTIONS="-S 0.0.0.0" Now, proftpd can be start successfully and not require of hostname resolving, but proftpd still can't start, because $OPTIONS is not using in ExecStartPre. If i open /lib/systemd/system/proftpd.service and find string: ExecStartPre=/usr/sbin/proftpd --configtest -c $CONFIG_FILE And change this to: ExecStartPre=/usr/sbin/proftpd --configtest -c $CONFIG_FILE $OPTIONS And save changes via "systemctl daemon-reload" All's good, proftpd correctly work. Well, i think that it correct, if $OPTIONS testing in ExecStartPre and this should be added by default. P.S. Unfortunately, this can't be overridden via /etc/systemd/system/proftpd.service.d/override.conf -- Best regards, Victor Simon FastVPS LLC
