[knot-dns-users] Migration from djbdns/tinydns to knot-dns.cz

Hello all, we want to migrate to a state of the art nameserver software. Our startingpoint is djbdns/tinydns. Our first step should be to to use zone transfer from tinydns to knot-dns (2.7.6). I configure the knot-dns a slave: # knotc conf-read … acl.id = master acl[master].address = 5.28.40.220 acl[master].action = notify remote.id = master remote[master].address = 5.28.40.220 … zone.domain = vtnx.net. zone[vtnx.net.].master = master zone[vtnx.net.].acl = master and add a initial soa rr for that domain: vtnx.net. 0 SOA ns1.vtnx.net. hostmaster.vtnx.net. 1 16384 2048 1048576 2560 This the exact soa of the running vtnx.net domain, but a diffrent serial. After triggering the notification from the master, i got this logging: Jan 24 07:53:19 ns1-neu knotd[26299]: info: [vtnx.net.] notify, incoming, 5.28.40.220@38668: received, serial none Jan 24 07:53:19 ns1-neu knotd[26299]: info: [vtnx.net.] refresh, outgoing, 5.28.40.220@53: remote serial 1548307450, zone is outdated Jan 24 07:53:19 ns1-neu knotd[26299]: warning: [vtnx.net.] IXFR, incoming, 5.28.40.220@53: malformed response SOA Jan 24 07:53:19 ns1-neu knotd[26299]: warning: [vtnx.net.] refresh, remote master not usable Jan 24 07:53:19 ns1-neu knotd[26299]: error: [vtnx.net.] refresh, failed (no usable master) What about "malformed response SOA"? Why is this an IXFR and no AXFR? - Frank -- Frank Matthieß Mail: frank.matthiess(a)virtion.de GnuPG: 9F81 BD57 C898 6059 86AA 0E9B 6B23 DE93 01BB 63D1 virtion GmbH Stapenhorster Straße 42b, DE 33615 Bielefeld Geschäftsführer: Michael Kutzner Handelsregister HRB 40374, Amtsgericht Bielefeld, USt-IdNr.: DE278312983
