Hi everyone,
We currently use dnsdist 1.4 and have a PowerDNS Recursor configured as
downstream server. Everything has a standard minimum configuration, with
..
client-tcp-timeout=60
..
configured on the PDNS Recursor.
The point is that in PDNS Recursor we can see the following entry log:
..
pdns_recursor: Timeout from remote TCP client <IP_DNSDIST>
..
We have been investigating and apparently the dnsdist does not close the
TCP sessions with the configured downstream server (PDNS Recursor),
having to close them the PDNS Recursor.
Is there a setting in dnsdist to set idle time of a TCP connection to a
backend server?
What is the default lifetime of a TCP session in dnsdist, once it is
waiting and not being used?
Thank you.
Kind regards,
Christian J. Calva
