can not restart samba
Solution 1:
sudo /etc/init.d/smbd restart
Rather than invoking init scripts through /etc/init.d, use the service(8) utility, e.g. service smbd restart
Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the stop(8) and then start(8) utilities, e.g. stop smbd ; start smbd. The restart(8) utility is also available.
smbd stop/waiting
smbd start/running, process 7831
So the commands to start/stop samba:
sudo stop smbd
sudo start smbd
For systemd related systems (ie. Ubuntu 16.04):
systemctl start smbd.service
systemctl stop smbd.service
Solution 2:
if you have installted samba package. you can find smbd, nmbd in the folder(/etc/init.d)
if not, it mean that your installation failed.
if yes, you can start the service via --
sudo /etc/init.d/smbd start
sudo /etc/init.d/nmbd start
or
sudo service smbd start
sudo service nmbd start
