Hi teor, Thank's for your answer with good explanation. yes it worked for (Authority.getN(3) + Relay.getN(1) + Client.getN(1) ) . For this i have installed tor-0.2.6.2-alpha-dev and download newest chutney where exit-v4.i or exit-v6.i don't exist . now i can see thorough wire-shark that which server i'm queering. But i got "Couldn't launch test003c (tor --quiet -f chutney/net/nodes/003c/torrc): 255" when i use (Authority.getN(3) + Client.getN(1) ) as you mentioned. and is it also possible to find which authority is acting exit-node?
