Identifying the bot to services
|
|
*******************************
|
|
|
|
The different methods listed here are in the order how they are usually recommended
|
|
by network operators.
|
|
|
|
Please also note that SASL and CertFP are only supported on Limnoria.
|
|
|
|
SASL PLAIN
|
|
----------
|
|
|
|
*To use SASL EXTERNAL, you must only configure CertFP and it's attempted automatically.*
|
|
SASL PLAIN is identifying using username and password, SASL EXTERNAL is identifying by
|
|
using CertFP which is explained later on this document. It doesn't need
|
|
username or password to be configured.
|
|
|
|
Note that SASL isn't supported on all networks. You can easily test if it's
|
|
supported with ``/msg SaslServ help`` and if you get response, SASL is
|
|
probably supported, if you don't get reply or get error about no such nick,
|
|
SASL isn't supported.
|
|
|
|
SASL is widely agreed as the best method to identify to services as it
|
|
identifies you before anyone (other than IRC operators) can see that you
|
|
are connected. To enable SASL, simply::
|
|
|
|
config networks.<network>.sasl.username AccountName
|
|
config networks.<network>.sasl.password P455w0rd
|
|
|
|
where you of course replace AccountName and P455w0rd with your actual
|
|
NickServ account name and password. Remember to replace ``<network>`` with
|
|
the real network name like ``freenode``.
|
|
|
|
CertFP
|
|
------
|
|
|
|
You can test if CertFP is supported by services simply by doing
|
|
``/msg NickServ cert``. If you get an error about "Insufficient parameters
|
|
for CERT", CertFP is supported, and if you get an error about unknown
|
|
command, it's not supported.
|
|
|
|
CertFP identifies you to services using a client (SSL) certificate and
|
|
naturally requires an SSL connection. It doesn't identify you as soon as
|
|
SASL, but unlike SASL, it identifies you even when services return from a
|
|
netsplit, unlike any other mechanism.
|
|
|
|
First you must generate a certificate, and the easiest method is probably
|
|
using OpenSSL which you should have even on Windows if you installed with pip::
|
|
|
|
openssl req -nodes -newkey rsa:4096 -keyout <BOT>.pem -x509 -days 3650 -out <BOT>.pem -subj "/CN=<BOT>"
|
|
|
|
Now you should have a ``<BOT>.pem`` file in the directory where you ran
|
|
the command, presumably your home directory and you only tell your
|
|
bot where to find it and tell NickServ that it belongs to you.
|
|
Note that you should replace ``<BOT>`` with the account name of your bot.
|
|
|
|
You have two choices, using the same certificate on all networks::
|
|
|
|
config protocols.irc.certfile /home/<username>/<BOT>.pem
|
|
|
|
or only on one or more network where it's manually configured::
|
|
|
|
config networks.<network>.certfile /home/<username>/<BOT>.pem
|
|
|
|
And lastly, you must tell the services what is your certificate
|
|
fingerprint, which you can find out with::
|
|
|
|
openssl x509 -sha1 -noout -fingerprint -in <BOT>.pem | tr -d ':' | tr 'A-Z' 'a-z'
|
|
|
|
This results in something like
|
|
``05dd01fedc1b821b796d0d785160f03e32f53fa8`` which you tell your bot to
|
|
tell services::
|
|
|
|
owner ircquote PRIVMSG NickServ :cert add 05dd01fedc1b821b796d0d785160f03e32f53fa8
|
|
|
|
Or if your bot identifies as you, you can do that by yourself with::
|
|
|
|
/msg NickServ cert add 05dd01fedc1b821b796d0d785160f03e32f53fa8
|
|
|
|
|
|
Remember to replace ``05dd01fedc1b821b796d0d785160f03e32f53fa8`` with your
|
|
own fingerprint! Next time your bot connects, it should get identified
|
|
automatically.
|
|
|
|
Server password
|
|
---------------
|
|
|
|
Many networks support identifying using ``username:password`` as server
|
|
password. If this is the case with your network (anything that uses a
|
|
charybdis-like IRCd), this should work for you. Note that this identifies
|
|
you after SASL so, your real host might be seen. To do this, simply::
|
|
|
|
config networks.<network>.password username:password
|
|
|
|
Replace ``<network>`` with the name of network, for example ``freenode``
|
|
and username:password with your real username and password.
|
|
|
|
ZNC users: since ZNC 1.0, ZNC's identification format has been
|
|
``username/network:password``.
|
|
|
|
Services plugin
|
|
---------------
|
|
|
|
The Services plugin comes with Supybot and should be an easy way to
|
|
identify your bot, but SASL and ``username:password`` as server password
|
|
are recommended over it. Start by loading Services with::
|
|
|
|
load Services
|
|
|
|
and then tell it what NickServ and ChanServ are called::
|
|
|
|
config plugins.services.nickserv NickServ
|
|
config plugins.services.chanserv ChanServ
|
|
|
|
Remember to replace NickServ/ChanServ with their real names if they have a
|
|
different name on any network. Note that they must have the same name on
|
|
all networks, and you must have the same password on all networks.
|
|
|
|
Now you can set your password::
|
|
|
|
services password Bot P455w0rd
|
|
|
|
makes the bot attempt identifying as Bot using password P455w0rd. Replace
|
|
them with your real nickname and password. Note that if you have multiple
|
|
nicknames, you must run ``services password`` for them all.
|
|
|
|
If your bot happens to get a nickname that isn't configured, it won't
|
|
know how to identify. You might be able to avoid this issue by loading
|
|
NickCapture, (``load NickCapture``) which attempts to regain the primary
|
|
nick, when it's possible, and when it regains the primary nick, the
|
|
identification should work.
