Hello
I build my own bind9 RPM for RHEL6 and RHEL7.
With the new version I get two errors when starting named.
Mar 25 16:41:56 dnsserver named[1348]: using default UDP/IPv4 port
range: [1024, 65535]
Mar 25 16:41:56 dnsserver named[1348]: listening on IPv4 interface lo,
127.0.0.1#53
Mar 25 16:41:56 dnsserver named[1348]: listening on IPv4 interface eth0,
192.168.10.100#53
Mar 25 16:41:56 dnsserver named[1348]: unable to set effective uid to 0:
Operation not permitted
Mar 25 16:41:56 dnsserver named[1348]: generating session key for
dynamic DNS
Mar 25 16:41:56 dnsserver named[1348]: unable to set effective uid to 0:
Operation not permitted
Mar 25 16:41:56 dnsserver named[1348]: sizing zone task pool based on 10
zones
From what I understand, the process named is running as user named already.
After it writes /var/run/named/named.pid, it tries to set the uid back to 0.
The same again after /var/run/named/session.key is written.
Bind is running in a chroot environment and the files are created with
the uid/gid of named.
As far as I can see, everything is working fine.
Why does named want to set the uid of itself back to 0?
Has anyone seen this as well?
Kind Regards
Stephan
