Well, I'm not sure what is cause this:

$ aorta -c -t telnet abcd1234abcd1234.onion 80

WARNING NOT testing if Tor handles all Internet traffic.

RUNNING telnet abcd1234abcd1234.onion 80
telnet: connect to address Connection timed out
Trying fa93:ac5e:c801:b104:ad21:2e27:0f18:b4f...
telnet: connect to address fa93:ac5e:c801:b104:ad21:2e27:0f18:b4f:  
Invalid argument


OTOH this works fine:

$ torsocks telnet abcd1234abcd1234.onion 80
Connected to abcd1234abcd1234.onion.
Escape character is '^]'.

Why is AORTA failing, also why is result of trying to connect on IPV6  
"Invalid argument"?
