Hello all,
I am new to IXFR feature and I found an example for using IXFR by
Cricket Liu at http://www.acmebw.com/resources/papers/bind82.pdf.
I tried to use IXFR feature in BIND 8.2.4 (release build) and after
working for a while, I get this error message in the log file.
====
Jul 19 04:42:24 ns3 named-xfer[1277]: Unexpected serial number for
zone domain.com: 479315
Jul 19 04:42:24 ns3 named[949]: Zone "domain.com" (file
domain.com.zone): no SOA RR found
Jul 19 04:42:24 ns3 named[949]: slave zone "domain.com" (IN) rejected
due to errors (serial 479743)
====
When this happen, the database file on the slave server is completely
wrong, I have to use named-xfer to do an AXFR and restart NAMED.
Has any one experienced the same problem?
Here is my named.conf files:
On Master:
options {
version "Not Available";
directory "/var/named";
check-names master warn; /* default. */
datasize 20M;
recursion No;
pid-file "/var/named/named.pid";
maintain-ixfr-base yes;
};
server x.x.x.x { /* our NS3 slave server */
transfer-format many-answers;
support-ixfr yes;
};
zone "domain.com" IN {
type master;
file "domain.com.zone";
check-names fail;
notify no;
allow-transfer {x.x.x.x; }; /* same as the slave above */
ixfr-base "domain.com.zone.ixfr";
};
======
On the slave:
options {
directory "/var/named";
check-names master warn; /* default. */
datasize 40M;
recursion No;
pid-file "/var/named/named.pid";
maintain-ixfr-base yes;
};
server Y.Y.Y.Y { /* Master server IP */
transfer-format many-answers;
support-ixfr yes;
};
zone "domain.com" IN {
type slave;
file "domain.com.zone";
masters {Y.Y.Y.Y; };
ixfr-base "domain.com.zone.ixfr";
};
======
Any helps would be greatly appreciated,
TIA.
