I have a full node that has been running for quite a while and everything is running fine. On a second machine on my private network, I start up a second full node and I use the connect option to specify that I am only connecting to my public node (using the internal address), like so: zcashd -conf=zcash.conf -connect=192.168.17.105 Everything looks normal and the node has only one connection and it gets all the latest blocks. However after some period of time has past, I notice that it has two connections. An outgoing connection to an external address has been added. I did not issue any commands between startup and noticing that there were two connections. Am I misunderstanding the -connect option with a single IP? I was expecting that the daemon would not initiate any connections besides to that one IP. When I do “zcash-cli getpeerinfo” I see: [ { “id”: 1, “addr”: “192.168.17.105”, “services”: “0000000000000005”, “lastsend”: 1526144103, “lastrecv”: 1526144103, “bytessent”: 6592, “bytesrecv”: 690177, “conntime”: 1526143684, “timeoffset”: 50, “pingtime”: 0.000849, “version”: 170005, “subver”: “/MagicBean:1.1.0/”, “inbound”: false, “startingheight”: 322072, “banscore”: 0, “synced\_headers”: 322075, “synced\_blocks”: 322075, “inflight”: [ ], “whitelisted”: false }, { “id”: 4, “addr”: “104.236.180.231:8233”, “addrlocal”: “xx.xxx.xx.xxx:xxxxx”, “services”: “0000000000000001”, “lastsend”: 1526144103, “lastrecv”: 1526144053, “bytessent”: 5561, “bytesrecv”: 80892, “conntime”: 1526143925, “timeoffset”: 50, “pingtime”: 0.026707, “version”: 170003, “subver”: “/MagicBean:1.0.15/”, “inbound”: false, “startingheight”: 322073, “banscore”: 0, “synced\_headers”: 322075, “synced\_blocks”: 322075, “inflight”: [ ], “whitelisted”: false } ] I am running zcashd version v1.1.0 on Ubuntu 16.04. ---

Do you have `addnode` set in your config file? ---

I do, to mainnet. But if it goes by what’s in the config file, then what’s the purpose of the -connect option? ---

I don’t know but I am guessing it uses both so just set the `connect` option and not `addnode` and see if that works? ---

> [@TO99](#): > > 104.236.180.231:8233 This IP address resolves to `mainnet.z.cash`. As @garethtdavies points out, you probably have `addnode=mainnet.z.cash` in your `zcash.conf`. I think the help information for `-connect` is misleading by saying it will “connect _only_ to the specified node(s)”. Looking at the source code (the best way to figure these things out!) – it is clear that it will also open connections to “added nodes”, i.e. those nodes specified using `addnode` either in the configuration file, command line, or RPC. It will not open additional _unspecified_ connections automatically if `-connect` is used. ---

Thanks for the clarification and thanks for taking time to look at the source! ---

Also by default zcashd will contact the dns seeders to try and find peers. To disable this behaviour, launch as `zcashd -dnsseed=0` or place this option in your config file.
