NTP服务器和客户端的设置及使用(EN版)

clients. Normally these packets are sent every 64 seconds. Both

xntpd and ntpdate have debug options but be aware that if you use

ntpdate -d it will only "go through the motions" and not actually

poll the network.

In this example we are using the ntp.client for ntp.conf and have

turned on xntpd -d

# /usr/lib/inet/xntpd -d &
20743
# Solaris tick = 10000
kernel vars: tickadj = 625, tick = 10000
adj_precision = 1, tvu_maxslew = 61875, tsf_maxslew = 0.0fd70a37
create_sockets(123)
bind() fd 19, family 2, port 123, addr 00000000, flags=1
bind() fd 20, family 2, port 123, addr 7f000001, flags=0
bind() fd 21, family 2, port 123, addr 8194c097, flags=1
init_io: maxactivefd 21
report_event: system event 'event_restart' (0x01) status

'sync_alarm, sync_unspec,
1 event, event_unspec' (0xc010)
input_handler: fd=19 length 48 from 8194c093 129.148.192.147
input_handler: fd=19 length 48 from 8194c093 129.148.192.147
input_handler: fd=19 length 48 from 8194c093 129.148.192.147
input_handler: fd=19 length 48 from 8194c093 129.148.192.147
input_handler: fd=19 length 48 from 8194c093 129.148.192.147
input_handler: fd=19 length 48 from 8194c093 129.148.192.147
input_handler: fd=19 length 48 from 8194c093 129.148.192.147

(129.148.192.147 is the host "jedi")

And at the same time we started snooping the ntp client on port 123

(ntp) we are expecting to see either multicast or broadcast NTP

packets.

# snoop -d le0 port 123
