ntpd listening on alias interfaces seems non-trivial
I have been attempting, without success, to get ntpd listening on an
alias interface on one of my general purpose boxes. It seems that ntpd
prefers to listen on localhost:ntp and eth0addr:ntp. It opens a socket
for *:ntp as well, but does not respond to queries on other addresses.
Here is some LSOF output demonstrating this..:
# lsof -p 16667 |grep UDP
ntpd 16667 root 4u IPv4 4493134 UDP *:ntp
ntpd 16667 root 5u IPv4 4493135 UDP localhost:ntp
ntpd 16667 root 6u IPv4 4493136 UDP hostname:ntp
I checked the archives, and it seems another poster had similar trouble
in Dec'02, but there were no apparent follow-up posts. Google has also
been less than revealing on this topic. All suggestions entertained.
