"Ignoring invalid proxy protocol query" with dnsdist and recursor

[karelbilek]

I am not sure if this is an issue or I am holding it wrong. I think I am holding it wrong, that's why I put it here and not to issues.

I start a new server with pdns-recursor and dnsdist, and on the same server, hook them up together. I put proxy protocol there. The recursor backend then shows "down" status.

The configs:

/etc/dnsdist/dnsdist.conf:

setACL({'0.0.0.0/0', '::/0'})

addLocal('<the IP address of this server>:53')
newServer({address="127.0.0.1:5300", enableProxyProtocol=true})
webserver("0.0.0.0:8083")

setWebserverConfig{acl="0.0.0.0/0",    dashboardRequiresAuthentication=false,
    statsRequireAuthentication=false}

/ect/powerdns/recursor.conf:

recursor:
  hint_file: /usr/share/dns/root.hints
  include_dir: /etc/powerdns/recursor.d
incoming:
 listen:
 - 127.0.0.1:5300 # default
 allow_from:
 - 0.0.0.0/0
 proxy_protocol_from:
 - 0.0.0.0/0
logging:
  trace: "yes"

The server then shows up "down" in dnsdist, and I see this in journal:
msg="Ignoring invalid proxy protocol query" subsystem="in" level="0" prio="Error" tid="1" ts="1755163035.141" length="36" proto="udp" remote="127.0.0.1:47201"

The versions are all latest stable from your debian repo; that is

ii  pdns-recursor  5.2.5-1pdns.debian12 amd64        PowerDNS Recursor
ii  dnsdist        2.0.0-1pdns.debian12 amd64        DNS loadbalancer

I am using bookworm debian.

When I remove enableProxyProtocol=true from dnsdist config, all works, but without proxy protocol.

Hi,

newServer({address="127.0.0.1:5300", enableProxyProtocol=true})

That's wrong. It works like this:

newServer({address="127.0.0.1:5300", useProxyProtocol=true})

enableProxyProtocol is the setting in addLocal().

Ahh that's it. Thanks, I confused the two settings
