Configuration
Creating a config file
To generate a basic configuration file, run znc --makeconf
after installation.
It is NOT a good idea to create a new config file manually, please use znc --makeconf
!
File locations
- Configuration - ZNC gets its configuration by reading the file
~/.znc/configs/znc.conf
. - Misc - Other files are also stored in the
~/.znc
directory, such as the SSL certificate (znc.pem) and the PidFile (znc.pid). - Local Modules - Stored in
~/.znc/modules
. ZNC will look in the local module directory first when trying to load a module. - Global Modules - Stored in
/usr/local/lib/znc
by default (where/usr/local
is the prefix you chose). This is/usr/lib/znc
if you used the Debian package. - Binaries -
znc
,znc-config
, andznc-buildmod
are all stored in/usr/local/bin
(or in/usr/bin
) by default. You can change this when you configure by using./configure --prefix=/whatever/path/you/want
.
Editing config
In most cases you should NOT edit znc.conf directly. Use webadmin instead.
If you really need to edit znc.conf by hand, do the following:
- pkill -SIGUSR1 znc
- to save current runtime configuration to znc.conf
- pkill znc
- to shutdown running ZNC instance
- Edit znc.conf
- znc
- to start it again with new configuration
Config file structure
This is outdated!
Basically, a configuration file consists of the following settings:
- AnonIPLimit - Limits the number of unidentified connections per IP.
- ConnectDelay - The time every connection will be delayed, in seconds. Some servers refuse your connection if you reconnect too fast. This affects the connection between ZNC and the IRC server; not the connection between your IRC client and ZNC.
- MaxBufferSize - Sets the global Max Buffer Size a user can have.
- ProtectedWebSessions - ...
- SSLCertFile - It's the TLS/SSL certificate file from which ZNC reads its server certificate.
- SSLCiphers - Allowed SSL ciphers. For example
SSLCiphers = ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+3DES:DH+3DES:RSA+AESGCM:RSA+AES:RSA+3DES:!aNULL:!MD5:!DS
- ServerThrottle - The time between two connect attempts to the same hostname.
- Skin - ...
- Motd - The "message of the day" which is sent to clients on connect via notice from *status. Can be specified multiple times.
- TrustedProxy - ...
- LoadModule - ...
- StatusPrefix - The prefix for the status and module queries. This setting may be overwritten by users.
- Version - The ZNC version that wrote this file.
- PidFile - Make ZNC write a pid file. ZNC does not need this itself. See the FAQ on info how to crontab ZNC.
- BindHost - This is a list of allowed bindhosts. It is used by the webadmin module for users to select one. (Set different bindhosts in "Settings" on your Webadmin-Interface first - one per line - to make them appear in users configs afterwards)
- Listener - Definition of a port that znc should listen on.
- Host - The host or IP on which ZNC listens.
- URIPrefix - Prefix that ZNC should make the web interface available under. This can be used to make ZNC available behind a reverse proxy.
- Port - The port number used.
- IPv4 - If this port is listening using IPv4.
- IPv6 - If this port is listening using IPv6.
- SSL - If this port is listening using SSL.
- AllowIRC - If IRC connections are allowed on this listener.
- AllowWeb - If web connections are allowed on this listener.
- User - The user definition, you can have more than one. Each user may only connect to one network, so you need a separate user for each network. This is intended behavior! (See the FAQ about multiple networks)
- Admin - If set to
true
, the user has admin rights (e.g. in the webadmin module). - Pass - Used by the client to connect to ZNC. A hash may be generated using
znc --makepass
.- Salt - ...
- Method - ...
- Hash - ...
- Allow - By default everyone is able to connect to ZNC as this user. With an Allow line you can restrict access to the specified IPs. Wildcards (*) are supported and multiple Allow lines can be set up.

- AppendTimestamp - Whether to append the timestamps to the message or not
- RealName - ...
- Bindhost - ...
- AutoClearChanBuffer - If set to
false
, it will buffer channels even while you are attached, and play the whole buffer back to you each time you connect. If set totrue
, it won't buffer channels while you are attached, and the buffer will be reset upon each playback. - AutoClearQueryBuffer - If set to
false
, it will buffer queries even while you are attached, and play the whole buffer back to you each time you connect. If set totrue
, it won't buffer queries while you are attached, and the buffer will be reset upon each playback. - Buffer - ...
- CTCPReply - A request-reply-pair for CTCP-requests. Format:
<request> <reply>
, e.g.VERSION unknown v1.0
- ChanModes - Default modes ZNC will set when you join an empty channel.
- Buffer - This is the amount of lines that the playback buffer will store before dropping off the oldest line. The buffers are stored in the memory by default.
- DCCBindHost - ...
- DenyLoadMod - If set to
true
, the user isn't able to load modules. - DenySetBindHost - If set to
true
, the user isn't able to change his vhost. - Ident - ...
- JoinTries - How often should ZNC try to join if the first join failed, e.g. due to channel mode +i/+k or if you're banned.
- LoadModule - Load a module for this user on startup.
- MaxJoins - How many channels should ZNC join at once. Lower this if you get disconnected for 'Excess flood.
- MaxNetworks - Maximum number of networks a user is allowed to have.
- MaxQueryBuffers - Maximum number of query buffers that are stored.
0
is unlimited. - MultiClients - Set this to
true
, if you want to be able to connect with multiple clients at once. - Nick - Your primary nick.
- PrependTimestamp - Whether to prepend the timestamps to the message or not

- StatusPrefix - The prefix for the status and module queries.
- TimestampFormat - The format for the timestamps used in buffers, for example
[%H:%M:%S]
- Timezone - Set this to your local setting, so you'll get correct times in your timestamps. Format is Europe/Berlin, and is case sensitive, dropdown box will not work in IE.

- FloodRate - How many lines per second ZNC sends after the FloodBurst
- IRCConnectEnabled - If set to
false
, user doesn't connect to IRC servers. - LoadModule - Load a module for this network on startup.
- Server - Adds a server to the list of servers this user will be able to connect to. If you want ZNC to connect to the IRC server using SSL, put '+' in front of the port number. The IP can be IPv6. If the server requires a password, just add it as the third argument. Format:
Server = <IP-Address/Host> [+]<Port> [<Password>]

Old versions
TODO:
- DCCVHost - This is the IP address used for DCC bouncing.
- BounceDCCs - If set to
true
, the DCCs will be bounced by ZNC. - DCCLookupMethod - If set to
default
, ZNC will use the IP the clients sends for the DCC connections; if set toclient
, ZNC will use the IP the client connects from. - Listener = [web_only|irc_only] [host or IP] [+]port - Configuration of listening port. Use web_only or irc_only, if you don't want port to be universal. Put host/IP before the port with a space between to bind to a specific IP (notice that in this case the listener can't listen on both ipv4 and ipv6). Then goes the port ZNC will listen on. If the port is prepended with a '+' (without space) then ZNC listens using SSL. You can have several listeners in one ZNC. (Introduced in 0.090, see next chapter for older versions)
- Listener4 or Listener6 - Exactly the same as Listener, but will use only IPv4 or IPv6.
- ISpoofFile - ZNC will write the ident of the user trying to connect to this file. Very useful if your shell supports oidentd.
- ISpoofFormat - The format of the ISpoofFile.
Before 0.096
- BindHost was named vHost
Before 0.090:
- Listen was similar to Listener4 from last version, without irc_only/web_only support.
- Listen6 was similar to Listener or Listener6 (depending on your OS) from last version, without irc_only/web_only support.
- TODO: When did Listeners become their own substructure?
