Hi! One of our customers uses Knot 2.6.7 as hidden master which sends NOTIFYs to our slave service. He reported that Knot can not send the NOTIFYs, ie:
knotd[10808]: warning: [example.com.] notify, outgoing, 2a02:850:8::6@53: failed (connection reset) It seems that Knot sometimes tries to send the NOTIFY with TCP (I see also NOTIFYs via UDP). Unfortunatelly our NOTIFY-receiver only supports UDP. So, this is the first time seeing a name server sending NOTIFYs over TCP. Is this a typical behavior in Knot? Can I force Knot to send NOTIFYs always over UDP? Thanks Klaus -- https://lists.nic.cz/cgi-bin/mailman/listinfo/knot-dns-users
