Hallo,
I have a machine which serves as NTP server. This machine has more (3) Network interfaces (+ loopback). By default NTP "binds" itself to all available interfaces, i.e. it listens on port 123 on all interfaces:
netstat -an|grep 123
udp 0 0 127.0.0.1.123 *.*
udp 0 0 1.2.3.4.123 *.*
udp 0 0 *.123 *.*
udp 0 0 1.2.5.4.123 *.*
udp 0 0 1.2.6.4.123 *.*
I would like to "bind" NTP to only one interface, say the 1.2.3.4. Is it possible? I do not find any hint on the net.
Thanks.
p.s. I am interested in a solution for linux and HP-UX, in case of OS dependency.
