Hello all, I don't know how to solve this : I have set up a master and a slave DNS. Two servers seem OK ... Configuration data are perfectly copied to slave, everything is fine . When I stop the master DNS deamon, the slave is able to respond to queries. But after some days the slave doesn't respond to queries anymore. Is this behaviour usual ? Many thanks,
This is a normal function of secondary DNS servers. The time until it stops answering queries is set by the "expire" parameter in the SOA RR. This page might help explain it a little more for you. http://www.zytrax.com/books/dns/ch8/soa.html
