NTP and Alias IP
Hello,
I have configured NTP (ntp-4.1.2-4) on REDHAT (2.4.21-15).
Clients and server, have same OS and NTP ver.
I want to use an alias IP address as NTP server to make it portable in
any failure case.
But I was not able to use Alias IP while the main IP is working.
[root@backupserver etc]# ntpq -np
remote refid st t when poll reach delay offset
jitter
==============================================================================
*192.168.210.33 127.127.1.0 11 u 63 64 375 0.152 -5.593
0.103
192.168.210.63 0.0.0.0 16 u - 128 0 0.000 0.000
4000.00
127.127.1.0 127.127.1.0 12 l 57 64 377 0.000 0.000
0.004
I have copied and modified ifcdg-eth0 to ifcfg-eth0:0 to make a alias
IP addr (210.33 is main and 210.63 is alias).
Please let me know whether I can use alias IP, as NTP server IP.
Best regards,
Shabahang Elmian,

Re: NTP and Alias IP
Hello,
