There are one or more missing IP addresses on the system message

[eglwolf]

For the last week I have been getting an email notice on this.

I checked what was suggested above in the thread:
"The ethernet device onto which new IP addresses are added. Devices detected with at least one IP are listed in the drop-down, or you may specify another device." and both options only have eno16780032

My email notification does state: "(XID u9fzav) The “ipaliases” service is down: The 'ipaliases' service has determined there are one (my server IP) or more missing IP addresses on the system."

It seems that in the logs this is what the errors are:

I am seeing a lot of these:

Not sure what I need to check or why this is happening.

Bump... Anyone?

Hello,

I am sorry to hear that you are experiencing this issue. It seems to me that this error might relate specifically to DHCP. Please note that we do not support DHCP and only support cPanel server's using a static IP. It may be best to ensure that your IP and netmask are "static" in your server's network configurations. If eno16780032 is the main networking device then the network configuration file should be located at: /etc/sysconfig/network-scripts/ifcfg-eno16780032

Are these errors and emails being sent to you frequently, or are they sent at a specific time? It may be likely that these emails are only being sent to you when the DHCP client is trying to renew the DHCP and failing.

Can you please check the configuration settings for the network device at the file I mentioned above and let us know if DHCP was enabled? Also, has DHCP always been enabled for this server?
