Hello, I'm Ziyu Yu, a gsoc applier.
I'm banned from the irc:
* alapagos.oftc.net NOTICE AUTH :*** Looking up your hostname...
* *** Checking Ident
* *** Your forward and reverse DNS do not match, ignoring hostname.
* *** No Ident response
* *** Banned autokilled: We suspect this host of participating in a
botnet. Mail support at oftc.net if you feel this in error. (2008-03-15

* Closing Link: 85.31.186.104 (Banned)

How could I do solve it? I use tor to do port mapping.
