**NOTE: This might be heavily freenode-specific, but these things should
|
|
|
|
|
work with other networks too, at least SASL and CertFP.**
|
|
|
|
|
|
2014-05-23 12:36:52 +02:00
|
|
|
I will document the four different methods to identify to services which I
|
2014-05-23 12:57:31 +02:00
|
|
|
use by myself. **I use all of these at the same time.**
|
2014-05-23 12:36:52 +02:00
|

|
|
|
## SASL
|
|
|
|
|
|
|
|
|
|
There isn't much to say about SASL as it's easy to configure as long as
|
|
|
|
|
your IRC client supports it. SASL identifies you before logging in, but it
|
|
|
|
|
won't help you in case services are down. The easiest way to check does
|
|
|
|
|
the network where you are support SASL is probably to whois or message or
|
|
|
|
|
both to the SaslServ.
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
/whois SaslServ SaslServ
|
|
|
|
|
/msg SaslServ help
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
If the network does support SASL, you should see something like this
|
|
|
|
|
which freenode gives:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
XX:XX:XX -- [SaslServ] (SaslServ@services.): SASL Authentication Agent
|
|
|
|
|
XX:XX:XX -- [SaslServ] services. (Atheme IRC Services)
|
|
|
|
|
XX:XX:XX -- [SaslServ] is a Network Service
|
|
|
|
|
XX:XX:XX -- [saslserv] End of WHOIS
|
|
|
|
|
XX:XX:XX -- SaslServ: This service exists to identify connecting clients to the network. It has no public interface.
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
There are different mechanisms for use with SASL. I personally use them in
|
|
|
|
|
this order with ZNC: `PLAIN DH-AES DH-BLOWFISH and EXTERNAL`.
|
|
|
|
|
|
|
|
|
|
This is what ZNC 1.5-git-3b01efc says about them:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
XX:XX:XX < *sasl> +-------------+----------------------------------------------------+
|
|
|
|
|
XX:XX:XX < *sasl> | Mechanism | Description |
|
|
|
|
|
XX:XX:XX < *sasl> +-------------+----------------------------------------------------+
|
|
|
|
|
XX:XX:XX < *sasl> | EXTERNAL | TLS certificate, for use with the *cert module |
|
|
|
|
|
XX:XX:XX < *sasl> | DH-BLOWFISH | Secure negotiation using the DH-BLOWFISH mechanism |
|
|
|
|
|
XX:XX:XX < *sasl> | DH-AES | More secure negotiation using the DH-AES mechanism |
|
|
|
|
|
XX:XX:XX < *sasl> | PLAIN | Plain text negotiation |
|
|
|
|
|
XX:XX:XX < *sasl> +-------------+----------------------------------------------------+
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Some notes:
|
|
|
|
|
|
|
|
|
|
* PLAIN is plain text as it says, so if you use it like I do, you should
|
|
|
|
|
use SSL.
|
|
|
|
|
* EXTERNAL is supposed to be used together with CertFP, but it doesn't
|
|
|
|
|
work with most of networks.
|
|
|
|
|
* It's not supported even by freenode.
|
|
|
|
|
* I don't know any network that supports it.
|
2014-05-23 12:57:31 +02:00
|
|
|
* This won't help you if services go down.
|
2014-05-23 12:36:52 +02:00
|
|
|
|
|
|
|
|
## CertFP
|
|
|
|
|
|
2014-05-23 13:26:30 +02:00
|
|
|
CertFP identifies you using SSL certificate which you must generate and
|
|
|
|
|
add to your NickServ account.
|
|
|
|
|
|
|
|
|
|
You can use this command at IRC to check if the network supports certfp.
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
/msg NickServ help cert
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
I am not sure how this happens on Windows, so you might need to look for
|
|
|
|
|
that information elsewhere unless someone decides to help me and tell
|
|
|
|
|
how does it happen. I am going to tell about OpenSSL.
|
|
|
|
|
|
|
|
|
|
### Generating the certificate
|
|
|
|
|
|
|
|
|
|
Open terminal and run this command and replae YOURNICKNAMEHERE.pem with
|
|
|
|
|
your nickname or something else which makes you know what it is
|
|
|
|
|
(**DO NOT SET PASSWORD FOR IT OR YOUR CLIENT MIGHT NOT BE ABLE TO USE IT**):
|
|
|
|
|
|
|
|
|
|
```
|
2014-06-04 16:43:47 +02:00
|
|
|
openssl req -nodes -newkey rsa:4096 -keyout YOURNICKNAMEHERE.pem -x509 -days 24855 -out YOURNICKNAMEHERE.pem -subj "/CN=Your Nickname"
|
2014-05-23 13:26:30 +02:00
|
|
|
```
|
|
|
|
|
|
|
|
|
|
This gives us file `YOURNICKNAMEHERE.pem` which you must give to your IRC
|
2014-06-04 16:43:47 +02:00
|
|
|
client.
|
|
|
|
|
|
|
|
|
|
**NOTE: This certificate is valid for 24855 days which is the maximum on
|
|
|
|
|
32-bit systems. This might not be very wise, but as we only use this cert
|
|
|
|
|
in IRC and we don't want to worry about regenerating it too often so we
|
|
|
|
|
have a very long time when it's valid. You should regenerate your
|
2014-06-04 17:10:23 +02:00
|
|
|
cert as often as you change your password or more even more often…**
|
|
|
|
|
|
|
|
|
|
Oh, and **don't close your terminal yet** as you will need it for HexChat.
|
2014-06-04 16:43:47 +02:00
|
|
|
|
|
|
|
|
### Telling your client (or bouncer to use the cert).
|
|
|
|
|
|
|
|
|
|
#### HexChat
|
|
|
|
|
|
2014-06-04 17:10:23 +02:00
|
|
|
Create a folder "certs" to your HexChat config and copy the .pem file
|
|
|
|
|
there and copy and rename it as `client.pem`.
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
mkdir -p ~/.config/hexchat/certs/
|
|
|
|
|
cp YOURNICKNAMEHERE.pem ~/.config/hexchat/certs/client.pem
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Now open your HexChat and press `CTRL + S` or go to `HexChat --> Network list` and check the settings for the networks that you use.
|
|
|
|
|
|
|
|
|
|
* Use SSL for all the servers on this network.
|
|
|
|
|
* Acccept invalid SSL certificates.
|
|
|
|
|
* Make sure that the login method **IS NOT** `SASL EXTERNAL (cert)`, as
|
|
|
|
|
said previously, it won't work.
|
|
|
|
|
* It appears that HexChat started to want to use it when I added the
|
|
|
|
|
certificate.
|
|
|
|
|
* If you use something that wants username, uncheck the `Use global user informtion`
|
|
|
|
|
or you must specify the username in the Network List and ZNC won't like
|
|
|
|
|
it.

|
|
|
|
2014-06-04 17:10:23 +02:00
|
|
|
Insert your .pem file somewhere where the bot can read it and tell your
|
|
|
|
|
bot to read use it while connecting with
|
2014-06-04 16:43:47 +02:00

|
|
|
|
2014-06-04 17:37:32 +02:00
|
|
|
I recommend you to `/script install iset.pl` for easier configuring when
|
|
|
|
|
you aren't following this.
|
2014-06-04 16:43:47 +02:00
|
|
|
|
2014-06-04 17:37:32 +02:00
|
|
|
Put the .pem file somewhere where your WeeChat can access it, preferably
|
|
|
|
|
`~/.weechat` or whenever your "WeeChat home" is and run the following
|
|
|
|
|
commands in WeeChat:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
/set irc.server_default.ssl_cert %h/YOURNICKNAMEHERE.pem"
|
|
|
|
|
/set irc.server_default.ssl on
|
|
|
|
|
/set irc.server_default.ssl_dhkey_size 1024
|
|
|
|
|
/set irc.server_default.ssl_verify off
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
1. Specifies where is the .pem file for all networks that don't have it
|
|
|
|
|
invidually specified.
|
|
|
|
|
2. Enables SSL for all networks by default unless otherwise configured.
|
|
|
|
|
3. Sets `dhkey_size` to `1024` (required by some networks like freenode).
|
|
|
|
|
4. Disables verifying the certificates (required for self-signed
|
|
|
|
|
certificates and I think that applies to our certificate too).

### Telling NickServ about your key
|
|
|
|
|
|
|
|
|
|
NickServ wants to know the fingerprint which you can get with the following
|
|
|
|
|
command:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
openssl x509 -sha1 -noout -fingerprint -in YOURNICKNAMEHERE.pem | sed -e 's/^.*=//;s/://g;y/ABCDEF/abcdef/'
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
which returns your fingerprint (**WHICH YOU MUST NOT SHARE WITH ANYONE**)
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
05dd01fedc1b821b796d0d785160f03e32f53fa8
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Now you can tell to NickServ about it.
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
/msg NickServ CERT ADD 05dd01fedc1b821b796d0d785160f03e32f53fa8
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
(replace that with your own fingerprint!) And nickerv replies to you
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
14:13:39 -- NickServ: Added fingerprint 05dd01fedc1b821b796d0d785160f03e32f53fa8 to your fingerprint list.
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### Testing
|
|
|
|
|
|
|
|
|
|
Now when you connect to freenode and have configured your IRC client to
|
|
|
|
|
use your new certificate, you should get identified automatically and
|
|
|
|
|
you should see your certificate by whoising yourself and running cert list
|
|
|
|
|
with NickServ.
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
/WHOIS YOURNICK YOURNICK
|
|
|
|
|
/MSG NickServ CERT LIST
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
replies
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
<...>
|
|
|
|
|
XX:XX:XX -- [YOURNICK] has client certificate fingerprint 05dd01fedc1b821b796d0d785160f03e32f53fa8
|
|
|
|
|
<...>
|
|
|
|
|
XX:XX:XX -- NickServ: Fingerprint list for YOURNICK:
|
|
|
|
|
XX:XX:XX -- NickServ: - 05dd01fedc1b821b796d0d785160f03e32f53fa8$$
|
|
|
|
|
XX:XX:XX -- NickServ: End of YOURNICK fingerprint list.
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### Notes
|
|
|
|
|
|
|
|
|
|
* You must recreate your certificate yearly.
|
|
|
|
|
* This will identify you with immediately so you are still visible to
|
|
|
|
|
/monitor.
|
|
|
|
|
* This will identify you after services return unlike other methods if you
|
|
|
|
|
happen to be on splitted server without services.
|
|
|
|
|
* Supported networks which I am on:
|
|
|
|
|
* freenode
|
|
|
|
|
* oftc
|
|
|
|
|
* piratenet
|
|
|
|
|
|
2014-05-23 12:36:52 +02:00
|
|
|
## Server password
|
|
|
|
|
|
2014-05-23 12:57:31 +02:00
|
|
|
This might not work with some networks, but this works with freenode.
|
|
|
|
|
All IRC clients should support settng password which to use while
|
|
|
|
|
connecting to server. Set it as `username:password` for freenode and you
|
|
|
|
|
are automatically identified when you connect.
|
|
|
|
|
|
|
|
|
|
Some notes:
|
|
|
|
|
|
|
|
|
|
* This is only known to work with freenode.
|
|
|
|
|
* You aren't identified immediately so as shown in the embedded gist,
|
|
|
|
|
your real host is visible for people who have you on `/monitor`.
|
|
|
|
|
* This won't help you if services go down.
|
|
|
|
|
|
2014-05-23 12:36:52 +02:00
|
|
|
## Automatic command
|
2014-05-23 12:05:31 +02:00
|
|
|
|
2014-05-23 12:57:31 +02:00
|
|
|
This works with probably every client. They support setting commands that
|
|
|
|
|
are automatically run as you connect and you can set the command
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
/msg NickServ identify username password
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
or whatever syntax the services on your network use.
|
|
|
|
|
|
|
|
|
|
Some notes:
|
|
|
|
|
|
|
|
|
|
* Your real host is still visible for /monitor ing people.
|
|
|
|
|
* Your client might send that command too late to prevent you from getting
|
|
|
|
|
to redirect channels for unidentified users and show your real host to
|
|
|
|
|
everyone.
|
|
|
|
|
* You might annoy people by joining twice and quitting once with "Changing
|
|
|
|
|
host".
