Thank you very much! Very useful. But is necessary for the server? No problem. Yes, it is necessary. If you're running a Slimcoin node at home and want it to be a listening client, then you'll need to ensure that your router supports UPNP and that the router is configured to allow incoming connections to the port and ipaddress of your node. UPNP allows your local host to connect via the default Slimcoin port, then you can advertise your ip address as a listening node for addnode inclusion. Do bear in mind that running a listening node at home will impact your upload usage if the size of the network is significant, as other nodes access your node for data which your node then uploads. Overloading your upload channel can nuke your download channel as the upload channel carries sync information for both up- and down-stream and a maxed-out upload channel can bring your download channel to a halt. Of course "up" and "down" are entirely perceptual. I once used the term "download from" in conversation with a network hardware engineering friend of mine. He cocked an eyebrow and said that he always thought of the net as below him, not above him, so he downloaded to the net and uploaded from it. I thought that was an excellent perception and have followed it ever since. Cheers Graham

So my idea that by PoBing at home one automatically provides a listening node to the net is completely wrong, right?

Not a listening node unless configured with listen=1 and UPNP-connected via the standard port. Cheers Graham

Not a listening node unless configured with listen=1 and UPNP-connected via the standard port. Edit: I configured my local node to listen=1 and ensured that the router was UPNP-enabled. My incoming IP address is 51.148.146.204 and this is what my restarted (old) server (configured with connect=51.148.146.204) RPC/API getpeerinfo call reports: "addr" : "185.150.190.19:41682", "inbound" : false, "height" : 2364810,
"addr" : "185.68.67.37:41682", "inbound" : false, "height" : 109603,
"addr" : "144.76.118.44:41682", "inbound" : false, "height" : 2364810,
"addr" : "51.148.146.204:41682", "inbound" : false, "height" : 2364810,
"addr" : "178.223.10.23:57705", "inbound" : true, "height" : 2364810,
"addr" : "178.223.10.23:63870", "inbound" : true, "height" : 2364810,
My local node is now listening. Cheers Graham

Not a listening node unless configured with listen=1 and UPNP-connected via the standard port. Cheers Graham I believe listen=1 is assumed when the parameter is missing from the .conf file. At least it was this way with all the wallets I used (and with slimcoind v5 too I get inbound connections in complete absence of any listen= setting). Not trying to be a smartass (well maybe a little bit ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif) ) Otherwise my node is still synching, I remember it takes quite some time but I hoped to get more than 300k blocks in 24 hours.

You are not using Grahams snapshot, are you? No, I am trying to synch from scratch again. While I understand loading the snapshot would make stabilize the network much faster, I want to see my node synched the traditional way. I tried with snapshot on a (much) earlier occasion and ended up synching from the network so I thought I'd go that way again.

My linux host 185.150.190.19 is on block 2365695 now, and so is my home minting wallet on windows. But the 22 connections of my linux host are all back a lot of blocks, why?

I found that if you stop and restart the node, the list of peers gets refreshed with updated heights. Yes, the node is very lazy about updating the heights of the peers, maybe that was a design trade-off at the time. Cheers Graham

Yes, the node is very lazy about updating the heights of the peers, maybe that was a design trade-off at the time. Cheers Graham I am not sure (and haven't checked in the code), but the height shown at getpeerinfo should probably be labeled "startingheight" as it is in other wallets. This would imply that the height shown is the height the peer node had when a connection was made. I don't think that it is getting updated after initial connection was made. (A quick test shows that these numbers do not seem to update after connect, though beware I have a talent for being totally wrong..)

Hi emrgohff, this issue is a bit hard for me to understand so I hope someone more senior will help us. I've found this conversation about the same message in bitcoin-qt: https://bitcointalk.org/index.php?topic=218447.0Can it be useful for you? Edit: Here is a bit late, so I'll be back tomorrow to see what has happened and whether I can go on supporting you.
