Re: how to check if peering truly works

I've found why peering was not syncing up tables - I must indicate the peers by IP address, not by hostname. If I list peers by hostname, HAproxy will try to connect to peers, but it refuses any peering requests sent to itself (does not even listen to the peering TCP port). So I made it work
