To start your znc, simply type:
[~]# znc
If you receive an error message saying your ZNC is already running such as this:
[~]# znc
[ .. ] Checking for list of available modules...
[ >> ] ok
[ .. ] Opening config [/home/username/.znc/configs/znc.conf]...
[ !! ] ZNC is already running on this config.
[ ** ] Unrecoverable config error.
This means you need to first stop your running ZNC process and then start it with the new <Pass> entry.
To find the PID # of your running ZNC type "ps x":
[~]#
ps x
PID TTY STAT TIME COMMAND
16650 pts/19 S 0:00 -bash
20721 ? Ss 0:09 SCREEN irssi
20722 pts/12 Ss+ 3:26 irssi
24068 ? Ssl 0:00 znc
24344 pts/19 R+ 0:00 ps x
Find the corresponding PID# in the PID column on the same line as your znc, and then kill it:[~]#
kill -9 24068
Then start your ZNC again:
[~]# znc
