Description Ralf Germann 2015-11-04 14:45:41 UTC
Description of problem: 
On RHEL 7 there seems to be a problem if you define more then one listening ip in /etc/named.conf. If you restart service named, everything looks fine. Listening on all available and configured ip addresses. But if you reboot your server it could be, that named is started, before all configured ip addresses / interfaces are ready to use and because of this named is only listening on some ips or in worst case only on localhost 127.0.0.1.

Temporary workaround which worked for me:
cp /usr/lib/systemd/system/named.service /etc/systemd/system/.
Add Wants=network.target to /etc/systemd/system/named.service
systemctl daemon-reload


Version-Release number of selected component (if applicable): bind-9.9.4-29.el7.x86_64


How reproducible: always, if you have a server with at least 2 interfaces. eth0 looks to the internet and eth1 is the one should listening on port 53.


Steps to Reproduce:
1. yum install bind-* -y
2. vi /etc/named.conf, edit line listen-on port 53 { 127.0.0.1; }; to
listen-on port 53 { 192.168.14.5; 127.0.0.1; }; (or use another ip)
3. systemclt enable named; systemctl start named
4. netstat -anp | grep 53 (everything should be fine)
5. systemctl reboot
6. netstat -anp | grep 53 (only listeing on 127.0.0.1)

Actual results:
Only listening on 127.0.0.1 after reoobt

Expected results:
Should listen also on 192.168.14.5
