I am trying to get Tor working with Irssi.

The directions at the bottom of this page Freenode Install Link say to

:~/.irssi$ tor MapAddress p4fsi4ockecnea7l.onion
Feb 12 04:26:51.101 [notice] Tor v0.2.1.29 (r318f470bc5f2ad43). This is experimental software. Do not rely on it for strong anonymity. (Running on Linux x86_64)
Feb 12 04:26:51.101 [warn] Command-line option 'p4fsi4ockecnea7l.onion' with no value. Failing.
Feb 12 04:26:51.101 [err] Reading config failed--see warnings above.

Or add it to the torrc file and reload irssi

.irssi$ cat /etc/tor/torrc  |grep 10.40.40
mapaddress  p4fsi4ockecnea7l.onion

This is a paste from within irssi after running $torify irssi

[04:33] Math::BigInt: couldn't load specified math lib(s), fallback to Math::BigInt::FastCalc at /usr/local/share/perl/5.10.1/Crypt/ line 6
[04:33] *** Irssi: Loaded script cap_sasl

So I thought it was a CPAN module issue.

cpan[1]> install Math::BigInt

This was also done for FastCalc and retried with force install.

What am I doing wrong?

You should put that mapaddress line to torrc file, not to tor command line.

After that, you must restart tor by running


or init script

/etc/init.d/tor restart

After that "torify irssi" should work. BigInt warning shouldn't be problem, as it is falling back to Math::BigInt::FastCalc.

...which, despite its name, is damn slow. Install Math::BigInt::GMP. (Although technically it is not necessary to use SASL DH-BLOWFISH when connecting over Tor or SSL; SASL PLAIN is enough. Still I couldn't stand seeing the warning every time.) – grawity Feb 12 '11 at 18:58
