Dear Ben,
Yes, this is on my laptop, which is running Ubuntu 14.04. The command
results are
agrebe@agrebe-laptop:~$ service zhm status
Usage: /etc/init.d/zhm {start|stop|restart|force-reload}
agrebe@agrebe-laptop:~$ pgrep zhm
[returns nothing]
This is the case both before and after I run renew.
Thank you,
Anthony
