[resolver-conf] Default msg_buffer_size too small for Unbound
In the default config, msg_buffer_size
is set to 4096. According to Unbound manual, this option limits the size of DNS messages unbound can handle and default should be set to 65552.
Such low value makes some domains unresolvable, for instance www.aquapark-uh.cz
, as reported here and confirmed by me.
Also please note that the very same option msg_buffer_size
is mapped to option net.bufsize
in Knot resolver, which is incorrect – option net.bufsize
of Knot Resolver is similar to edns-buffer-size
option of Unbound.
