Adding and Starting an NTP Server
Someprotocols,suchasKerberos,musthaveaccurateinformationaboutthecurrenttime.Inthosecases,you
canaddanNTP(NetworkTimeProtocol)servertoyourESXihost.

To manage an NTP Server

--add toaddanNTPservertothehostspecifiedin<conn_options>anduseahostname
orIPaddresstospecifyanalreadyrunningNTPserver.
vicfg-ntp <conn_options> -a 192.XXX.XXX.XX
2Runvicfg-ntp --starttostarttheservice.
vicfg-ntp <conn_options> --start
3Runvicfg-ntp --listtolisttheservice.
vicfg-ntp <conn_options> --list
4Runvicfg-ntp --stoptostoptheservice.
vicfg-ntp <conn_options> --stop
5Runvicfg-ntp --deletetoremovethespecifiedNTPserverfromthehostspecifiedin<conn_options>.
vicfg-ntp <conn_options> --delete 192.XXX.XXX.XX

ForIPv4networks,noadditionaloptionsarerequired.
vicfg-route <conn_options> --add <network_ip> <netmask_IP> <gateway_ip>
Forexample,toaddarouteto192.XXX.100.0through192.XXX.0.1:
vicfg-route <conn_options> -a 192.XXX.100.0/24 192.XXX.0.1
or
vicfg-route <conn_options> -a 192.XXX.100.0 255.255.255.0 192.XXX.0.1
ForIPv6networks,use--family v6
vicfg-route <conn_options> -f V6 --add <network_ip_and_mask> <gateway_ip>
Forexample:
vicfg-route <conn_options> -f V6 --add 2001:10:20:253::/64 2001:10:20:253::1
