I'm seeing a lot of timeout messages for the daemon trying to connect to peers on port 7333 for some reason, which isn't an i0coin port? I have port 7337 in my conf file, so not sure why it's still trying to use that port.
According to the code, 7333 is the usual listening port and 7332 is the RPC port. But you are free to configure any other port as well in the config file (including 7337).
Apart from that, auxpow seems to be working fine & I'm receiving payments as usual.
Sounds good! The "old-client" branch, however, is only a minor change necessary to upgrade the network to the new client in the future. So no big surprise that auxpow still works ... but it is a good step, we need as many of the new nodes running as possible. Thanks for testing!
