###
###'              ejabberd configuration file
###
###

### The parameters used in this configuration file are explained in more detail
### in the ejabberd Installation and Operation Guide.
### Please consult the Guide in case of doubts, it is included with
### your copy of ejabberd, and is also available online at
### http://www.process-one.net/en/ejabberd/docs/

### The configuration file is written in YAML.
### Refer to http://en.wikipedia.org/wiki/YAML for the brief description.
### However, ejabberd treats different literals as different types:
###
### - unquoted or single-quoted strings. They are called "atoms".
###   Example: dog, 'Jupiter', '3.14159', YELLOW
###
### - numeric literals. Example: 3, -45.0, .0
###
### - quoted or folded strings.
###   Examples of quoted string: "Lizzard", "orange".
###   Example of folded string:
###   > Art thou not Romeo,
###     and a Montague?

###.  =======
###'  LOGGING

##
## loglevel: Verbosity of log files generated by ejabberd.
## 0: No ejabberd log at all (not recommended)
## 1: Critical
## 2: Error
## 3: Warning
## 4: Info
## 5: Debug
##
loglevel: 4

##
## rotation: Describe how to rotate logs. Either size and/or date can trigger
## log rotation. Setting count to N keeps N rotated logs. Setting count to 0
## does not disable rotation, it instead rotates the file and keeps no previous
## versions around. Setting size to X rotate log when it reaches X bytes.
## To disable rotation set the size to 0 and the date to ""
## Date syntax is taken from the syntax newsyslog uses in newsyslog.conf.
## Some examples:
##  $D0     rotate every night at midnight
##  $D23    rotate every day at 23:00 hr
##  $W0D23  rotate every week on Sunday at 23:00 hr
##  $W5D16  rotate every week on Friday at 16:00 hr
##  $M1D0   rotate on the first day of every month at midnight
##  $M5D6   rotate on every 5th day of the month at 6:00 hr
##
log_rotate_size: 10485760
log_rotate_date: ""
log_rotate_count: 1

##
## overload protection: If you want to limit the number of messages per second
## allowed from error_logger, which is a good idea if you want to avoid a flood
## of messages when system is overloaded, you can set a limit.
## 100 is ejabberd's default.
log_rate_limit: 100

###.  ===============
###'  NODE PARAMETERS

##
## net_ticktime: Specifies net_kernel tick time in seconds. This options must have
## identical value on all nodes, and in most cases shouldn't be changed at all from
## default value.
##
## net_ticktime: 60

###.  ================
###'  SERVED HOSTNAMES

##
## hosts: Domains served by ejabberd.
## You can define one or several, for example:
## hosts:
##   - "example.net"
##   - "example.com"
##   - "example.org"
##
hosts:
  - "localhost"

##
## route_subdomains: Delegate subdomains to other XMPP servers.
## For example, if this ejabberd serves example.org and you want
## to allow communication with an XMPP server called im.example.org.
##
## route_subdomains: s2s

###.  ============
###'  Certificates

## List all available PEM files containing certificates for your domains,
## chains of certificates or certificate keys. Full chains will be built
## automatically by ejabberd.
##
## certfiles:
##   - "/etc/letsencrypt/live/example.org/*.pem"
##   - "/etc/letsencrypt/live/example.com/*.pem"
##
## If your system provides only a single CA file (CentOS/FreeBSD):
## ca_file: "/etc/ssl/certs/ca-bundle.pem"

###.  =================
###'  TLS configuration

## Note that the following configuration is the default
## configuration of the TLS driver, so you don't need to
## uncomment it.
##
## define_macro:
##   'TLS_CIPHERS': "HIGH:!aNULL:!eNULL:!3DES:@STRENGTH"
##   'TLS_OPTIONS':
##     - "no_sslv3"
##     - "cipher_server_preference"
##     - "no_compression"
##   'DH_FILE': "/path/to/dhparams.pem" # generated with: openssl dhparam -out dhparams.pem 2048

    ##
    ## If TLS is compiled in and you installed a SSL
    ## certificate, uncomment this line:
    ##

  ## Direct-TLS for C2S (XEP-0368). A good practice is to forward
  ## traffic from port 443 to this port, possibly multiplexing it
  ## with HTTP using e.g. sslh [https://wiki.xmpp.org/web/Tech_pages/XEP-0368],
  ## so modern clients can bypass restrictive firewalls (in airports, hotels, etc.).

## ===============
## API PERMISSIONS
## ===============
##
## This section allows you to define who and using what method
## can execute commands offered by ejabberd.
##
## By default "console commands" section allow executing all commands
## issued using ejabberdctl command, and "admin access" section allows
## users in admin acl that connect from 127.0.0.1 to  execute all
## commands except start and stop with any available access method
## (ejabberdctl, http-api, xmlrpc depending what is enabled on server).
##
## If you remove "console commands" there will be one added by
## default allowing executing all commands, but if you just change
## permissions in it, version from config file will be used instead
## of default one.
##

###.  ====
###'  ACME
##
## In order to use the acme certificate acquiring through "Let's Encrypt"
## an http listener has to be configured to listen to port 80 so that
## the authorization challenges posed by "Let's Encrypt" can be solved.
## 
## A simple way of doing this would be to add the following in the listening
## section and to configure port forwarding from 80 to 5280 either via NAT
## (for ipv4 only) or using frontends such as haproxy/nginx/sslh/etc.
##   - 
##    port: 5280
##    ip: "::"
##    module: ejabberd_http

acme:

   ## A contact mail that the ACME Certificate Authority can contact in case of
   ## an authorization issue, such as a server-initiated certificate revocation.
   ## It is not mandatory to provide an email address but it is highly suggested.
   contact: "mailto:example-admin@example.com"


   ## The ACME Certificate Authority URL.
   ## This could either be:
   ##   - https://acme-v01.api.letsencrypt.org - (Default) for the production CA
   ##   - https://acme-staging.api.letsencrypt.org - for the staging CA
   ##   - http://localhost:4000 - for a local version of the CA

  ##   The module for S2S dialback (XEP-0220). Please note that you cannot
  ##   rely solely on dialback if you want to federate with other servers,
  ##   because a lot of servers have dialback disabled and instead rely on
  ##   PKIX authentication. Make sure you have proper certificates installed
  ##   and check your accessibility at https://check.messaging.one/
