I am cross-posting this from the CentOS list - there have been plenty
of views but no answers and I'm not sure exactly where to post...
So I have CentOS 6 (x64) - apparently nptd "Ver. 4.2.4p8". My problem
is that I have too many IPs for ntpd to do a listen on every one. So I
tried restricting both with adding -I eth0 on the command line
parameters (in /etc/sysconf/ntpd) and with the interface instruction
in /etc/ntp.conf. Neither works, and ntpd refuses to start.
May 3 09:40:57 MyHost ntpd: Listening on interface #1005
eth1:132235, 10.132.235.1#123 Enabled
May 3 09:40:57 MyHost ntpd: Listening on interface #1006
eth1:132236, 10.132.236.1#123 Enabled
May 3 09:40:57 MyHost ntpd: Listening on interface #1007
eth1:132237, 10.132.237.1#123 Enabled
May 3 09:40:57 MyHost ntpd: Too many sockets in use, FD_SETSIZE
