[[Categorytags: Apps]]IRC Chat mIRC bounce Chatzilla server<br><br>[http://www.amahi.org/apps/znc ZNC] is an Internet Relay Chat (IRC bounce with many advanced features such as ) network bouncer or BNC. It can detach the client from the actual IRC server, and also from selected channels. Multiple clients from different locations can connect to a built-single ZNC account simultaneously and therefore appear under the same nickname on IRC. It supports Secure Sockets Layer (SSL) secured connections and IPv6. == About ZNC in Amahi ==* Currently '''BETA''' for Amahi 7.* The application makes use of your HDA first admin user. To log in to the web interface, persistent connection (detaching), multiple usersenter that user name and the password is ''admin''. You can change the password once logged in to anything you desire.* ZNC appears in the '''Servers''' tab so you can stop, per channel playback buffer, SSL, IPv6, transparent DCC bouncingstart, and c++ module support, to name restart as needed.* There is a [http://wiki.znc.in/FAQ FAQ] on the ZNC web site which may help with common questions. == Initial Configuration ==There are a fewsteps you need to complete before ZNC is ready.# Log into the web interface using credentials as noted in the Special Instructions on the Applications Installed tab. Expand the ZNC app and you will see them displayed.# Once logged in, select User Settings from the menu on the left.# To be continued... == IRC Client Setup ===== mIRC ===*When using the mIRC client you will need to connect to ZNC using the following command:<!--<nowiki>/server -m <yourHdaIp> -p 26244 -g gZNC -w <username>:<password> -d ZNC</nowiki>--> /server -m <yourHdaIp> -p 26244 -g gZNC -w <username>:<password> -d ZNC

== ZNC Commands = Chatzilla (FireFox Add-on) ===Commands are given to ZNC by messaging After installation of Chatzilla Add-on you can enter the virtual user *status. Likewisefollowing in your browsers address bar: irc://<YouHdaIp>:26244/<channel>/?pass=<ZncUser>:<ZncUserPass>or irc://<YourHdaIp>:26244/, modules are communicated to by messaging *modname as well. needpass?pass=<ZncUser>:<ZncUserPass>or SSL ircs://<YourHdaIp>:26244/,needpass?pass=<ZncUser>:<ZncUserPass>

== Client Commands ==Commands are given to ZNC by messaging the virtual user *status. Likewise, modules are communicated to by messaging *modname as well. Alternatively you can use ''/znc command '' instead of ''/msg *status command '' and ''/znc *module command '' instead of ''/msg *module command ''. <br />

When you add new servers, ensure you precede the port number with a '''+''' (the pre-installed server is already set for SSL communication).  '''NOTE:''' See [http://en.znc.in/wiki/Configuration ZNC Configuration] for more guidance on customization. == Generating a SSL Certificate ==You can use the following openssl commands to generate a certificate: openssl req -nodes -newkey rsa:2048 -keyout znc.key -x509 -days 365 -out znc.crtcat znc.crt znc.key > znc.pemCopy this file to your '''/home/username/.znc''' directory (replace ''username'' with your first admin user name) and restart ZNC: systemctl restart znc.service  '''NOTE:''' See [http://wiki.znc.in/Cert ZNC Cert] for more guidance on certificates. == Backup Personal Settings ==You can have your setting automatically backed up or do it manually. This script will email them to you as a compressed file. * Install a few dependencies: yum install p7zip mailx* Create <b>znc-backup.sh</b> and place it in /var/hda/web-apps/znc/html directory (ensure you change the USER as noted below):<pre>vi /var/hda/web-apps/znc/html/znc-backup.sh</pre><pre>#!/bin/bash### You can change this if you wantUSER=`/var/hda/platform/html/script/first-admin`MAILADRESSE1=rootYOUREHOST=localhost### Facultatif change :DIR=/home/$USER/.zncTAR_PATH=`whereis tar | cut -d ' ' -f 2`p7zip_PATH=`whereis 7za | cut -d ' ' -f 2`SendEmail_PATH=`whereis mailx | cut -d ' ' -f 2`DATEI1=$(date +%Y-%m-%d)_znc_backup.tarDATEI2=$(date +%Y-%m-%d)_znc_backup.tar.7zDATUM=$(date +%Y-%m-%d)sevenzp="a -t7z -m0=lzma -mx=9 -mfb=64 -md=32m -ms=on -mhe=on"### no Change after hereif [ ! -d "$DIR" ]; then echo "You MUST change DIR variable.

For '''''chat.freenode.net''''' this IP is:'''''140.211.166.3'''''* Go to your ZNC webadmin page* Login using your username and password* Click on "Your Settings" * Edit the server name in the '''''Servers:''''' text box.ZNC will pickup this new server name the next time trying to connect (wait a minute or so). === Install Fails ===If you have installed ZNC multiple times without success, perform the following as '''root''' user: yum -y erase znc** Once the RPMs have been removed, perform install.* Check ''/var/log/amahi-app-installer.log'' for details.<br>[[Category: Apps]]
