Connecting to freenode

The freenode network can be accessed via the freenode webchat or using an IRC client such as irssi, WeeChat, ERC, HexChat, Smuxi, Quassel or mIRC.

You can connect to freenode by pointing your IRC client at chat.freenode.net on ports 6665-6667 and 8000-8002.

Accessing freenode Via SSL

freenode provides SSL client access on all servers, on ports 6697, 7000 and 7070. Users connecting over SSL will be given user mode +Z, and is using a secure connection will appear in WHOIS (a 671 numeric). Webchat users will not currently appear with +Z or the 671 numeric, even if they connect to webchat via SSL.

In order to verify the server certificates on connection, some additional work may be required. First, ensure that your system has an up-to-date set of root CA certificates. On most linux distributions this will be in a package named something like ca-certificates. Many systems install these by default, but some (such as FreeBSD) do not. For FreeBSD, the package is named ca_root_nss, which will install the appropriate root certificates in /usr/local/share/certs/ca-root-nss.crt.

Certificate verification will generally only work when connecting to freenode.net. If your client thinks the server's certificate is invalid, make sure you are connecting to chat.freenode.net rather than any other name that leads to freenode.

For most clients this should be sufficient. If not, you can download the root certificate from IdenTrust.

Client SSL certificates are also supported, and may be used for identification to services. See this kb article. If you have connected with a client certificate, has client certificate fingerprint f1ecf46714198533cda14cccc76e5d7114be4195 (showing your certificate's SHA1 fingerprint in place of f1ecf46...) will appear in WHOIS (a 276 numeric).

Accessing freenode Via Tor

freenode is also reachable via Tor, bound to some restrictions. You can't directly connect to chat.freenode.net via Tor; use the following hidden service as the server address instead:

freenodeok2gncmy.onion

The hidden service requires SASL authentication. In addition, due to the abuse that led Tor access to be disabled in the past, we have unfortunately had to add another couple of restrictions:

If you haven't set up the requisite SASL authentication, we recommend SASL EXTERNAL. You'll need to generate a client certificate and add that to your NickServ account. This is documented in our knowledge base.

Note that due to the SSL certificates not matching the hidden service, you might have to disable the verification in your client. If your client supports key pinning, you can verify our Tor server's public key fingerprint:

E0:1B:31:80:56:D9:78:C4:2B:2D:3F:B2:DB:81:AB:03:15:59:BF:04:7E:31:E8:60:5F:98:07:A1:BB:8F:A3:0D

You'll then want to tell your client to try the EXTERNAL mechanism. We lack comprehensive documentation for this, but it's a feature in most modern clients, so please check their docs for instructions for now.
