我们已限制 NTP 仅监听 eth0，其余的将忽略。但是，我们可以看到，在对 ntp.conf 进行更改后，它尝试监听广播，但无法绑定地址并出现意外错误。
ntpd[89217]: ./../lib/isc/unix/ifiter_ioctl.c:617: unexpected error:
ntpd[89217]: eth2:6: getting broadcast address: Cannot assign requested address
ntpd[89217]: i/o error on routing socket No buffer space available – disabling
ntpd[5410]: ./../lib/isc/unix/ifiter_ioctl.c:617: unexpected error:

ntpd[5410]: ntpd exiting on signal 15
ntpd[1508]: ntpd exiting on signal 15
以下是来自客户服务器的 ntp.conf：-
猫ntp.conf
fudge 127.127.1.0 层 10
Authentication stuff
keys /etc/ntp.keys
path for keys file
trustedkey 1
define trusted keys
requestkey 1
server 172.23.5.8 iburst
server 172.23.5.9 iburst
restrict 172.23.5.8
restrict 172.23.5.9
key (7) for accessing server variables
controlkey 15 # key (6) for accessing server variables
extra lines to fix issue about NTP Daemon
interface listen eth0
interface ignore wildcard
您可以看到这个是 /var/lib/NTP 日志文件。

希望你有所收获。
谁能告诉我如何修复这个错误？
