# ZNC Modules

Suppose you want to install [clientbuffer](/https://github.com/CyberShadow/znc-clientbuffer/archive/master.zip), a 3rd party module. Download the source code:

    $ cd
    $ ftp https://github.com/CyberShadow/znc-clientbuffer/archive/master.zip
    $ unzip master.zip
    $ mv znc-clientbuffer-master/{Makefile,clientbuffer.cpp} znc-1.8.2/modules/
    $ cd znc-1.8.2/modules/
    $ gmake
    $ doas su mkdir /home/znc/home/znc/.znc/modules
    $ doas cp clientbuffer.so /home/znc/home/znc/.znc/modules/
    $ doas chown -R znc:daemon /home/znc/home/znc/.znc/modules/


## Tips

Please don't use fail2ban for znc; one team tried to do it and immediately              

broke their web panel because fail2ban banned 127.0.0.1 (which relayd uses):

I had to unload the module to restore web panel access.                                 



Znc has some extra modules like tcl, python etc, if you want to active one or more of these modules for your znc the command would be

./configure.sh  --enable-tcl  --enable-python 

for help or list of the options you can use 

./configure --help

NB. you got to be in znc directory to issue this command.
