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. -- Jeff
