You can connect to Indymedia IRC server through a Tor Hidden Service, instead of just using Tor to connect to the normal
irc.indymedia.org address (which is also possible, by the way).
The hidden service has the address
If your tor software is too old and can’t connect to the previous address, you can use the following address:
h7gf2ha3hefoj5ls.onion — however, if it is possible to upgrade your tor software to a more recent version we strongly recommend that you do this and use the first address mentioned above.
You should connect to it without SSL on port 6667. The SSL/TLS is already present in Tor, so it’s not necessary here.
Warning: SSL/TLS connections are currently allowed through the hidden service (only the “old” v2 onion service), however the service will present to you a certificate that is only valid for host name
irc.indymedia.org, thus not for the onion host name. Because of this we recommend not to use SSL/TLS with the hidden service since it’s impossible to trust the certificate in this situation.
