Hello,
Environment: Solaris10 SPARC, BIND 9.8.1
Anomaly: In our logs, we have been noticing "open_socket... permission denied..." entries. For example,
named[15910]: [ID 873579 daemon.warning] dispatch 2bcf50: open_socket(::#2049) -> permission denied: continuing
named[15910]: [ID 873579 daemon.warning] dispatch 2bcb58: open_socket(0.0.0.0#2049) -> permission denied: continuing
named[15910]: [ID 873579 daemon.warning] dispatch 2bcb58: open_socket(0.0.0.0#4045) -> permission denied: continuing
I believe 2049 and 4045 are considered privileged ports (beyond the standard <1024 ones).
According to the OS, we have these for TCP:
# ndd /dev/tcp tcp_extra_priv_ports
2049
4045
6112
And we have these for UDP:
# ndd /dev/udp udp_extra_priv_ports
2049
4045
I'm not sure what the cause is and what a fix should be, if any.
Anyone?
