|---|---|
| Description: | Configures list of Jabber IDs, which has ability to use Admin Interface. |
| Context: | server-mode and gateway-mode |
| Type: | list of Jabber IDs |
| Default: | empty list |
This option configures list of Jabber IDs, which has ability to use Admin Interface. In server-mode, you also have to specify service.admin_password to set password for Admin Interface. In gatewa-mode, you just specify the list of Jabber IDs, Spectrum 2 does not check any password in gateway-mode.

| Type: | list of JIDs |
| Default: | empty list |
Configures list of servers from which users can connect and register Spectrum 2 transport. This option is used together with registration.enable_public_registration option. If registration.enable_public_registration is set to 0, you can use this option as a white-list, to enable users from particular domain to use your Spectrum 2 instance, but disallow it to any other users.
Following part of config file disables public registrations and allows only users from xmpp.org and jabber.org to use this Spectrum 2 instance:
[service]
allowed_servers=xmpp.org
allowed_servers=jabber.org
[registration]
enable_public_registration=0
service.backend
| Key | val |
|---|---|
| Description: | Configures path to backend executable. |
| Context: | server-mode and gateway-mode |
| Type: | string |
| Default: | empty string |
This option configures path to backend executable. When user connects, Spectrum 2 spawns new backend process to handle this user's session. Usually single backend is shared by more users. This can be configured using service.users_per_backend.
service.backend_host
| Key | val |
|---|---|
| Description: | Configures hostname or IP to which backend connects. |
| Context: | server-mode and gateway-mode |
| Type: | string |
| Default: | localhost |
This option configures hostname or IP to which backend connects. When Spectrum 2 is started, it listens on service.backend_port to communicate with backends. When new backend is started, it connects to the hostname configured by this option and starts handling new users sessions.
service.backend_port
| Key | val |
|---|---|
| Description: | Configures port on which Spectrum 2 listens on for backends connections. |
| Context: | server-mode and gateway-mode |
| Type: | integer |
| Default: | 0 |
This option configures port on which Spectrum 2 listens on for backends connections. If the value of this option is 0, then Spectrum 2 uses randomly generated port number.
service.cert
| Key | val |
|---|---|
| Description: | Configures certificate to be used for SSL encryption in server-mode. |
| Context: | server-mode |
| Type: | string |
| Default: | empty string |
This option configures full path to PKCS#12 certificate which is used for SSL in server-mode. To find out, how to create such certificate, please read Using SSL in server mode.
service.cert_password
| Key | val |
|---|---|
| Description: | Configures password for certificate which is used for SSL encryption in server-mode. |
| Context: | server-mode |
| Type: | string |
| Default: | empty string |
This option configures password which is used to decrypt PKCS#12 certificate (if it is encrypted). For more information about SSL with Spectrum 2, read service.cert option description.
service.group
| Key | val |
|---|---|
| Description: | Configures group under which Spectrum 2 instance runs. |
| Context: | server-mode and gateway-mode |
| Type: | string |
| Default: | empty string |

service.jid
| Key | val |
|---|---|
| Description: | Configures Jabber ID of Spectrum 2 instance |
| Context: | server-mode and gateway-mode |
| Type: | string |
| Default: | empty string |
This option configures Jabber ID of particular Spectrum 2 instance. Usually it is a hostname on which this Spectrum 2 instance
runs, so for example icq.domain.tld. Note that you have to have DNS records configured for this hostname, so clients will be able
to find out your Jabber server (in case you are running Spectrum 2 in gateway-mode) or the Spectrum 2 itself (if you are running
Spectrum 2 in server-mode).
service.password
| Key | val |
|---|---|
| Description: | Configures password to be used to connect XMPP server |
| Context: | gateway-mode |
| Type: | integer |
| Default: | 0 |
This option configures port on which Spectrum listens to in server-mode or to which connects in gateway-mode. In server-mode the default port for XMPP servers is 5222, so you should use this port. In gateway-mode, you have to at first configure your server to allow Spectrum 2 to connect it as its component. On many servers, the default component port is 5347, but this option depends on particular XMPP server and its configuration.
service.pidfile
| Key | val |
|---|---|
| Description: | Configures path to file when Spectrum 2 stores its process ID. |
| Context: | server-mode and gateway-mode |
| Type: | string |
| Default: | /var/run/spectrum2/$jid.pid |
This option configures path to file when Spectrum 2 stores its process ID. This file is later used by spectrum2_manager to determine,
if this particular Spectrum 2 instance runs.
service.port
| Key | val |
|---|---|
| Description: | Configures port on which Spectrum listens to in server-mode or to which connects in gateway-mode. |
| Context: | server-mode and gateway-mode |
| Type: | integer |
| Default: | 0 |
This option configures port on which Spectrum listens to in server-mode or to which connects in gateway-mode. In server-mode the default port for XMPP servers is 5222, so you should use this port. In gateway-mode, you have to at first configure your server to allow Spectrum 2 to connect it as its component. On many servers, the default component port is 5347, but this option depends on particular XMPP server and its configuration.
service.server
| Key | val |
|---|---|
| Description: | Configures hostname or IP address of server to which Spectrum 2 connects to. |
| Context: | gateway-mode |
| Type: | string |
| Default: | empty string |
This option configures hostname or IP address of server to which Spectrum 2 connects to. It is used only in gateway-mode and you should configure it to point to hostname or IP of your XMPP server.
service.server_mode
| Key | val |
|---|---|
| Description: | Configures if Spectrum 2 works in server mode or gateway mode |
| Context: | server-mode and gateway-mode |
| Type: | boolean |
| Default: | 0 |
If this option is true, Spectrum 2 works in server-mode and acts as standalone server.
User then logins legacy networks by logging XMPP account like this one: my_msn_name%hotmail.com@msn.domain.tld.
Advantages:
- Passwords are not stored on server.
- Roster synchronization is easy, because Spectrum 2 acts as normal server.
- If you want to use Spectrum 2 as wrapper between different networks, you don't need database or Jabber server as another layer.
- Using SRV records you can easily run Spectrum 2 on different machines to scale it.
Disadvantages:
- Clients have to support more accounts to connect more legacy networks (Therefore they will need have to use more TCP connections).
If this option is false, Spectrum 2 acts as normal XMPP component (gateway).
You then have to configure an external XMPP server (like Prosody or Ejabberd) to serve the subdomain you want to use for Spectrum 2 (for example "icq.domain.tld"). Spectrum 2 in gateway mode then connects the XMPP server as its component and users are able to find out "icq.domain.tld" in Service Discovery, register it and use it.
Advantages:
- Users can use more legacy networks using single XMPP account (and using single TCP connection).
- It's easy to extend existing XMPP servers using gateway mode.
Disadvantages:
- Passwords are stored (even in encrypted form) on server.
- Roster (contact list) synchronization can be problematic, because it depends on the client user uses. This can be improved by usage of Remote Roster protoXEP.
- You have to setup XMPP server and use database even if you only want to use Spectrum 2 as a tool to connect legacy networks using XMPP protocol.
service.user
| Key | val |
|---|---|
| Description: | Configures user under which Spectrum 2 instance runs. |
| Context: | server-mode and gateway-mode |
| Type: | string |
| Default: | empty string |
This option configures name of user under which Spectrum 2 instance runs. When Spectrum 2 is started, it switches from current user (usually root) to this user.
service.users_per_backend
| Key | val |
|---|---|
| Description: | Configures maximum number of users who share single backend process. |
| Context: | server-mode and gateway-mode |
| Type: | integer |
| Default: | 100 |
This option configures maximum number of users who share single backend process. Value of this option depends on number of online
users on your Spectrum 2 instance in the same time. There is no strict consensus on what is the best value. Every backend is separated
process and you probably want to keep the number of processes per Spectrum 2 instance less than 30. So if you have 1000 users, it
could be sane to use users_per_backend=50. Another idea is to have the same number of backends as the number of CPU cores of the
machine where Spectrum 2 is running.
If you have too big value of users_per_backend, you have just single backend process for all users and Spectrum 2 will not perform so well as if you have more backends running for the same user-base. Also, if there is some problem with single backend, it will affects only users connected using this particular backend, so it is good idea to have more backends running. However, the more backends you have the more processes the machine has and since some point, it will become less useful. There is also some memory overhead, so if you run 500 users on single backend, it will take little bit less memory than 500 users on 5 backends (but it is not significant unless you decide to have hundreds of backends).
If you presume to have just few users on your personal server, it can be useful to configure service.users_per_backend=1. Ever user will
get his own separated backend process.
For bigger user-base, you have to increase the service.users_per_backend value, but there is no optimal value to be suggested yet.
service.working_dir
| Key | val |
|---|---|
| Description: | Configures path to directory when Spectrum 2 stores its data files. |
| Context: | server-mode and gateway-mode |
| Type: | string |
| Default: | /var/lib/spectrum2/$jid |
This option configures path to directory when Spectrum 2 stores its data files like for example SQLite3 database.
