Identifying the bot to services

The different methods are listed in order which I (Mikaela) recommend. You can use all of these methods or only some of them. I (Mikaela) personally use SASL, CertFP and Server password.

Please also note that SASL and CertFP are only supported on Limnoria.

SASL

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.
