從ejabberd服務器上的單個設備註冊多個用戶？

Question

我正在smack chat library上ejabberd服務器上工作。 ejabberd配置後，我可以同時註冊多個設備的用戶同時登錄多個用戶和用戶可以正確聊天，但問題是，當我從同一個移動設備快速註冊多個用戶。它越來越錯誤，如：

org.jivesoftware.smack.sasl.SASLErrorException: SASLError using DIGEST-MD5: not-authorized 

和ejabberd.log文件，我發現：

<error code='500' type='wait'><resource-constraint xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'/><text xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'>Users are not allowed to register accounts so quickly</text></error> 

但是，當我要去的一段時間它工作正常後，註冊從同一臺設備的用戶。 我在互聯網上搜索很多，但我找不到合適的解決方案，所以請給我適當的解決方案，並有什麼辦法來減少單個設備的用戶註冊時間。我ejabberd.yml文件：

### 
###'   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: 5 

## 
## 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 

## 
## watchdog_admins: Only useful for developers: if an ejabberd process 
## consumes a lot of memory, send live notifications to these XMPP 
## accounts. 
## 
## watchdog_admins: 
## - "admin@TT_CPU_076" 

###. =============== 
###' 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: 
    - "TT_CPU_076" 

## 
## 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

###' DATABASE SETUP 

## ejabberd by default uses the internal Mnesia database,

## sql_password: "password" 
## 
## If you want to specify the port: 
## sql_port: 1234 
## 
## If you use PostgreSQL, have a large database, and need a 
## faster but inexact replacement for "select count(*) from users"

Answer 1

查找registration_timeout標籤在你ejabberd.yml文件&值設置爲無窮。

例：

## By default the frequency of account registrations from the same IP 
## is limited to 1 account every 10 minutes. To disable, specify: infinity 

registration_timeout: infinity 

你應該能夠在同一個設備註冊多個用戶。雖然出於安全原因建議禁用帶內註冊。
